The operation of brief description die arrangement 14.Fig. 7-A, 7-B, 7-C and 7-D are the cam characteristic curves, they are represented respectively: rising and the descending motion of the outer supportingmember 76 of going upmould assembly 72 under ring cam set 66 andcam bawl 90 act on simultaneously; Theinner bracing member 78 oflast mould assembly 72 acts in ring cam set 68 andcam bawl 104 and the rising and the descending motion of effect ring cam set 70 andcam bawl 106 time; Rising and descending motion under the outer supportingmember 180 oflower mould assembly 74 acts inring cam set 58 andcam bawl 192; Theinner bracing member 182 oflower mould assembly 74 acts inring cam set 60 andcam bawl 222 and the rising and the descending motion of effect ring cam set 62 andcam bawl 224 time.With reference to these characteristic curves, Fig. 1 and Fig. 8-A to 8-F as can be seen, when diemember 14 was in charging zone A shown in Figure 1,last mould assembly 72 andlower mould assembly 74 were separated from one another on the vertical direction shown in Fig. 8-A.In this case, quantitative inadvance plastics 278 as polyethylene or polypropylene are added in the diearrangement 14 frommaterial feeder 4 with molten state, specifically, be added in exactly on the diemember 240 of lower mould assembly 74 (following also will be described indetail material feeder 4).When diearrangement 14 forwarded compression moulding district B to the direction of arrow shown in Figure 1, because diearrangement 14 rotations, outer supportingmember 76 andinner bracing member 78 descended gradually, and the outer supportingmember 180 oflower mould assembly 74 andinner bracing member 182 rise gradually.Reach among Fig. 1 before the position shown in the B-1 at diearrangement 14, diemember 202 upper ends oflower mould assembly 74 are just withstood in the lower end of the diemember 140 oflast mould assembly 72, therefore, the diemember 140 oflast mould assembly 72 is with respect to outer supportingmember 76 and the diemember 138 that is fixed on above it, overcome spring assembly 156(Fig. 3) the elastic force impetus and be enhanced, and be reduced to above-mentioned retracted position (8-B with the aid of pictures) and stop with above-mentioned extended position (8-A with the aid of pictures).When diearrangement 14 forwarded position shown in the B-2 to the position shown in the B-1 of Fig. 1, because the outer supportingmember 76 oflast mould assembly 72 and diemember 138 and 140 descend, theouter support member 180 oflower mould assembly 74 and diemember 202 also descended.As a result, in the B-2 position, die member 138,140 and 202 presents the position shown in Fig. 8-B.On the other hand, when diearrangement 14 when position B-1 forwards position B-2 to,lower mould assembly 74inner bracing members 182 and diemember 240 are clamped in their uppermost positions, further do not rise.But the inner bracing member oflast mould assembly 72 78 continues to descend and the lower end of diemember 110 is pressed on the plastics 278.Therefore, diemember 110 is with respect toinner bracing member 78 and diemember 108, overcome spring assembly 134(Fig. 3) the resiliency urged effect, rise to the position shown in Fig. 8-B (in this position, the lower surface of themain part 126 of diemember 110 withstands the lower surface of diemember 108).In addition, shown in Fig. 8-B, plastics are compressed and distortion between diemember 110 and 240 a little.When diearrangement 14 forwards the end (initial end of cooling zone C) of compression moulding district B to from position B-2, theinner bracing member 78 oflast mould assembly 72, diemember 108 and 110 descend a little.As a result, compare with 8-C from Fig. 8-B, generally can understand,plastics 278 are compressed and are deformed into jar 252.About this point, with reference to figure 7-A and 7-C, comparison diagram 8-B and 8-C just will appreciate that, because in the above-mentioned compression moulding, the outer supportingmember 76 oflast mould assembly 72 and the diemember 138 and 140 that the is driven predetermined amount that risen, and, the outer supportingmember 180 oflower mould assembly 74 and thedie member 202 that the is driven predetermined amount that also risen, just quickenedplastics 278 flowing between the internal circular surfaces of the outer round surface of diemember 110 and die member 202,140 and 138, constituting perimeter wall, and be compression molded intojar 252 by the predetermined way precision.

Below further narration compression moulding operation.At charging zone A, regulate the plastics that are added on thedie arrangement 14 quite accurately and reach desired amount, even possible, but also be quite difficult, in general, the amount that is added to the plastics in thedie arrangement 14 has some change.Diearrangement 14 in thecompacting assembly 2 designed according to this invention, the amount ofplastics 278 changes can be by the thickness that changesjar 252 top board walls 254t(Fig. 6) Come proofreaies and correct, and need not change the effective depth from the inner surface oftop board wall 254 toperimeter wall 256 lower endsh(Fig. 6).Specifically, in the diearrangement 14 that illustrates, diemember 110 on theinner bracing member 78 oflast mould assembly 72 and 108 is in the position shown in Fig. 8-C, the outer supportingmember 76top die members 140 and 138 oflast mould assembly 72 in the position shown in Fig. 8-C (therefore, thedie member 202 oflower mould assembly 74 is in the position shown in Fig. 8-C), effect in the time of by ring cam set 68 andcam bawl 104, effect effect and ring cam set 66 andcam bawl 90 time mechanically is limited on the fixing position in the time of ring cam set 70 and cam bawl 106.Relative, in thelower mould assembly 74, effect effect and ring cam set 62 andcam bawl 224 time in the time of ring cam set 60 andcam bawl 222,inner bracing member 182 mechanically is limited on the fixing position in the position shown in Fig. 8-C, butspring assembly 236 is inserted betweeninner bracing member 182 and the die member 240.Spring assembly 236 makes flexibly upwards skew of diemember 240, with enoughbig plastics 278 of defeating, but the active force greater than the elastic thrust ofspring assembly 236 is added on the diemember 240, causes that diemember 240 overcomes the elastic reaction ofspring assembly 236 and moves down.Therefore, if the quantity of theplastics 278 that added is a bit larger tham the amount of being scheduled to, diemember 240 descends the thickness of top board wall 254 a little from the precalculated positiontBecome big, the amount that descends with diearrangement 240 is consistent.So just having offseted addedplastics 278 exceeds and neededly is.On the other hand, if the amount of addedplastics 278 is less than predetermined amount a little, diemember 240 rises a little from the precalculated position.As a result, the thickness oftop board wall 254tBecome thinner, the amount that rises with diemember 240 is consistent, so just to slightlyplastics 278 short amount.Usually, the effective depth ofjar 252hFor sealing property or the like is important, but the thickness oftop board wall 254tItself does not have bad influence to covering sealing property of 252 or the like.Therefore, no matter the quantity of addedplastics 278 has some to change, diearrangement 14 can pressing mold goes out to meet the jar that sealing property etc. requires.

The direction that continues press Fig. 1 arrow 10 at diearrangement 14 is rotated and when passing through cooling zone C, the die member 110,108,140 oflast mould assembly 72 and 138 and thedie member 202 and 204 oflower mould assembly 74 remain on the position shown in Fig. 8-C.During this, thejar 252 of mold pressing is sufficiently cooled.When diearrangement 14 had left cooling zone C and has been rotated further, theinner bracing member 76 and the outer supportingmember 78 oflast mould assembly 72 rose gradually, and the outer supportingmember 180 oflower mould assembly 74 andinner bracing member 182 descend gradually.At this moment, inlast mould assembly 72, diemember 110 drops to the extreme lower position shown in Fig. 8-D with respect toinner bracing member 78 and diemember 108, and diemember 140 drops to the extended position shown in Fig. 8-D with respect to outer supportingmember 76 and die member 138.As a result, diemember 110 and 140 is in the state shown in Fig. 8-D.In this case, diemember 108 and 138 andjar 252 break away from engagement.During situation in being in Fig. 8-D, 174 effects of 176 pairs of cam follower devices of fixed cam gear, take second angle position to being blocked the resiliency urged effect thatpart 158 overcomesspring 170, follow as mentioned above referring to Fig. 3 and Fig. 4, when moving to after the diemember 110 when leavingjar 252, diemember 140 is prevented from, and stops it to rise with respect to outer supportingmember 76 and diemember 138, and stops it to get back to retracted position from extended position.Therefore stoped the outer supportingmember 76 oflast mould assembly 72 and thedie member 140 that is driven and 138 to rise, but inner bracing member oflast mould assembly 72 78 and the diemember 110 and 108 that is driven are rotated further, and the outer supportingmember 180 oflower mould assembly 74 and thedie member 202 that is driven,inner bracing member 182 and the diemember 240 that is driven continue to descend.Really, die member 110,202 and 240 has leftjar 252 shown in Fig. 8-E.Then, the outer supportingmember 76 oflast mould assembly 72 and diemember 140 and 138 recover to rise, and shown in Fig. 8-F, diemember 140 also breaks away fromjar 252, on products discharging district D,jar 252 drops on thegoods conveying device 6 and (hereinafter will describe in detail).When diearrangement 14 continues when charging zone A rotates, the outer supportingmember 76 oflast mould assembly 72 andinner bracing member 78 continue to rise, the results that the outer supportingmember 180 oflower mould assembly 74 andinner bracing member 182 further descends, the die member 108,110,138 oflast mould assembly 72 and 140 and the diemember 202 and 204 oflower mould assembly 74 rotate back into the state shown in Fig. 8-A.

Now, referring to Fig. 9 and Figure 10, fixed pedestal 312 is arranged on the precalculated position.Pedestal 312 has pair of sidewalls 314, and the L-R direction of pressing Figure 10 each other is provided with, and horizontal base plate 316 is fixed between this pair of sidewalls 314.Be formed separately the guide wall 317 of inwardly stretching out in these pair of sidewalls 314 upper ends.Bracing frame 292 is contained in this between the guide wall 317, so that it can be free to slide by the L-R direction among Fig. 9 with perpendicular to the direction of Figure 10 paper.In more detail, on two sides of bracing frame 292, be formed separately the guide wall 318 of L type cross section, bracing frame 292 is the vertical form of plate on the whole, and guide wall 318 is separately fixed at by means of rolling bearing system 320 on the lower surface of guide wall 317 of pair of sidewalls 314.As a result, bracing frame 292 is dressed up slidably.As shown in Figure 9, between bracing frame 292 and fixing pedestal 312, a fluid pressure cylinder mechanism 322 is installed, so that bracing frame 292 slides.This fluid pressure cylinder mechanism 322 is made up of pneumatic cylinder, and it can extend by the L-R direction of Fig. 9.The a pair of fastening spike 326 of cylinder 324 usefulness that constitutes cylinder mechanism is fixed on the lower surface of bracing frame 292, and the piston that also constitutes pneumatic cylinder mechanism has a free end that is fixed on fixed pedestal 312 tail ends.Therefore, when fluid pressure cylinder mechanism 322 was in straight configuration, bracing frame 292 was in the operating position shown in Fig. 9, (using the operating position shown in the solid line among Fig. 1).When fluid pressure cylinder mechanism 322 was in retracted mode, the predetermined distance of bracing frame 292 motion was to the left end of Fig. 9 and be in the off-position shown in the double dot dash line among Fig. 1.If necessary, bracing frame 292 can manually slide, and does not use the drive unit as fluid pressure cylinder mechanism 322.

Also referring to Fig. 9 and Figure 10, supportingseat 338 is fixed on bracingframe 292 front ends (right end position among Fig. 9).Supportingseat 338 has individualhorizontal component 340 to stretch out (among Fig. 9 to the right) forward, and diehead 286 is contained on the horizontal component 340 (hereinafter will illustrate in greater detail diehead 286).In addition, be arranged on below thehorizontal component 340, be contained on the supportingseat 338 by the reinforced retention device (hereinafter will be described in more detail) of 342 said fingers.Big portion element (hereinafter will describe in detail) by the shearing device of 348 said fingers is contained on the bracing frame 292.Therefore, diehead 286, reinforcedretention device 342 andshearing device 348 most of members of forming move along with the motion of bracingframe 292 between the off-position shown in the operating position shown in Fig. 1 and 9 solid lines and Fig. 1 double dot dash line.

Describe die head 286 in detail referring to Figure 11.Die head 286 is made up of the module 350 of approximate parallelepiped and coldplate 351 and template 352, and coldplate 351 and template 352 are fixed on the front surface of module 350 successively.A side at module 350 and coldplate 351 has relatively large notch portion 354, and it is corresponding with this otch 354 to be formed with through hole 356 on template 352.Notch portion 354 and through hole 356 are passed in the rotating shaft 358 of shearing device 348, and rotary cutter 360 is contained in the front end in the rotating shaft 358, and it stretches out the rotating shaft 358 and the rotary cutter 360 that hereinafter will further specify shearing device 348 above template 352(forward).Also have an extrusion mouth 362 on the template 352.Have squeezing passage 364 on module 350 and the coldplate 351, extend to extrusion mouth 362 from above-mentioned inlet.Like this, the plastics 278 of fusing, flow through the inlet that squeezing passage 364 is added to die head 286 and are extruded extrusion mouth 362 by conduit 284 from extruder 282.The plastics of extruding from extrusion mouth 362 278 are cut off by the cut-out sword 368 of the cutting knife 360 of the direction rotation of pressing arrow 366, and drop on the die arrangement 14 that is among the charging zone A (Fig. 1), more particularly, drop on the die member 240 of lower mould assembly 74 of die arrangement 14 (8-A with the aid of pictures simultaneously).The mobile circulation canal (not showing) of circulating cooling medium (for example water) is arranged on coldplate 351 and by means of coldplate 351 and template 352, rotary cutter 360 is also cooled off by the cooling medium by circulation canal.

The inventor's experience explanation, when more relatively and rotatingspeed rotary cutter 360 of the quantity of the plastics of being cut 278 is relatively low, along withrotary cutter 360 rotates, theplastics 278 of fallingtemplate 352 lower limbs alongtemplate 352 surfaces that downcut Come by theblade 368 ofrotary cutter 360 certainly will be advanced to the lower surface oftemplate 352, and stick on thetemplate 352, do not leavetemplate 352 fully and fall.In order to hamper this situation of ending, the air-flow injection apparatus is housed also indie head 286.

Referring to Figure 12 and 13, in die head 286, the front end 372 of the lower surface of template 352 be forward with acclivitous chamfering.The air-flow injection apparatus includes gas channel 373 and many fumaroles 374, and gas channel 373 is opened on template 352, and in front end 372 back a bit.Air communication is crossed 373 sides from template 352 (right side Figure 12) horizontal expansion and is surpassed a predetermined length.These many fumaroles 374 are spaced from each other in the horizontal and extend vertically downward, and their adjacent front end 372 are also opened any place, on template 352 lower surfaces front end 372 back.Provide gas from gas supply station (not shown) to gas passage 373, it can be a compressed air, and from fumarole 374 ejections.Effect owing to the air-flow that sprays from fumarole 374 has prevented that effectively plastics from entering on the lower surface of template 352, and these plastics 278 are along with the rotation of cutting knife 360 falls Come, and the surface of crossing template 352 flows to template 352 lower edge.The effect of air-flow also helps plastics 278 to leave from the blade of rotary cutter 360.Then, plastics 278 along fully and the track that accurately forms fall, offer the die member 240(Fig. 8 of lower mould assembly 74 in the die arrangement 14-A).If desired, as shown in figure 14, fumarole 374 can be from gas channel 373 downward-sloping forward and them towards template 352 front ends 372 openings.In addition, as shown in figure 15, also may make two kinds of fumaroles 374, a kind of fumarole from gas channel substantially vertically downward, another kind of fumarole 374 tilts to the front lower place from gas channel 373.Replace form as another kind, fumarole 374 can be that horizontal continuous elongated narrow slit Come replacement is this at the many fumaroles 374 that laterally are provided with at certain intervals, as shown in figure 16.

Referring to Figure 17, describe reinforcedblocking mechanism 342 in conjunction with Fig. 9 and Figure 10 in detail.Reinforced blocking mechanism 342 comprises receivingmember 376 andpositioner 378, and receiving member is elongated rectangular channel, and positioner includes air cylinder device.Reception stand 380 is fixed on the supporting seat 338 (sees Fig. 9 and Figure 10), and supportingseat 338 is fixed on the bracingframe 292 by suitable connecting elements (not shown).Receivingmember 376 is placed on and receives on thestand 380, and removable.Mainly referring to Figure 17, thebrace 382 that level is stretched out is fixed on the side surface of receivingmember 376, and the upper end of vertically extendingpin 384 is fixed on the brace 382.Supportingmember 386 also is contained in (Fig. 9 and Figure 10) on the supportingseat 338, and the front end of supportingmember 386 has the pin-and-hole ofvertical direction.Pin 384 is inserted in the pin-and-hole of supportingmember 386, androtatable.Connector 390 is fixed on the lower end of thepin 384 that stretches out from pin-and-hole downwards, andconnector 392 andconnector 390 are pivotally connected.The front end ofpiston rod 394 is being fixedconnector 392 in the air cylinder device that constitutespositioner 378.

On the other hand, supportingmember 396 also is fixed on (Fig. 9 and Figure 10) on the supporting member 338.The bottom of thecylinder barrel 398 of the air cylinder device offormation detent mechanism 378 is pivotally connected by means of vertical connectingpin 400 with supporting member 396.Like this, when constituting the air cylinder device withdrawal ofpositioner 378, receivingmember 376 is around bearingpin 384 rotations.When air cylinder device withdrawal makes receivingmember 376 rotate by the direction shown in thearrow 402 and when being in off working state shown in Figure 17 solid line, a side of receivingmember 376 abuts against on thefirst stop sheet 404 that receives on thestand 380, rotates thereby stoped receivingmember 376 further to press the direction shown in the arrow 402.When being tightened to,cylinder receiving member 376 is rotated and when making it remain on operating position shown in Figure 17 double dot dash line by the direction of arrow 406, the another side of receivingmember 376 abuts against on thesecond stop sheet 408 that receives stand 380, rotates thereby stoped receivingmember 376 to continue to press the direction shown in the arrow 406.

As top mainly described referring to Figure 11, extrude and be rotated theplastics 278 that cuttingknife 360 downcuts from theextrusion mouth 362 ofdie head 286, thedie member 240 that leaves cuttingknife 360 and thelower mould assembly 74 in thedie arrangement 14 falls.When receivingmember 376 remained on above-mentioned operating position, the front end of receivingmember 376 was in the path thatplastics 278 fall.Therefore,plastics 278 drop on the receivingmember 376, have prevented that theseplastics 278 from dropping on thedie member 240 of lower mould assembly 74.On the other hand, when receivingmember 376 was in off-position, it left the path thatplastics 278 fall, soplastics 278 drop on thedie member 240.

Front end at receivingmember 376 has air-flow injection apparatus 410.Air-flow injection apparatus 410 includes thesquare body 412 that is contained in receivingmember 376 front ends.Square body 412gas channel 414 that has been shaped, it traverses across needed length from an end ofsquare body 412, many fumaroles that are horizontally arranged atinterval 416 extend back fromgas channel 414, and opening (can be made one or more elongated slot Come and replace this many fumaroles 416) on the rear surface of square body 412.Gas channel 414 links to each other with the air supply source (not shown) via the pipeline that contains by-pass valve control.When receivingmember 376 was in the operating position, by-pass valve control was opened compressed air is delivered togas channel 414 from air supply source.Gas sprays fromfumarole 416 then.The air-flow effect of ejection also drops on theplastics 278 of receivingmember 376 front ends, and force them to move towards the rear end of receivingmember 376.

Referring to Figure 17 and Fig. 9 and Figure 10, thepassage mechanism 418 that is made of pipeline that is provided among the embodiment that illustrates links to each other with receiving member 376.As shown in figure 10,passage mechanism 418 hasdismountable connection carriage 421 to be contained on the bracingframe 292,carriage 421 is fixed on the inner surface ofpassage mechanism 418 upper ends, also be fixed on and connect on thecarriage 419,carriage 419 is fixed on the lower surface of bracingframe 292, therefore, passage mechanism can be with the motion campaign of bracing frame 292.The inlet ofpassage mechanism 418 upper ends is positioned at the position with receivingmember 376 rear end correspondences.The lower end ofpassage mechanism 418 and fixingresin container 420 communicate.By the inlet of air-flow towards theplastics 278 of receivingmember 376 rear end reinforcings from receivingmember 376admission passage mechanisms 418,pass passage mechanism 418, enter resin container 420.In resin container 420.The water of the inside makes plastic cool and sclerosis.Be not bonded on its inwall by thispassage mechanism 418 for theplastics 278 that make fusing are fine, preferably provide the current (not shown) at the inlet ofpassage mechanism 418 with suitable mechanism, flow to outlet from inlet, carryplastics 278 in the current by thispassage mechanism 418.

Be also noted that the following fact about reinforced blocking mechanism 342.When extruder 282 operation began one section preset time, the action of extruder 282 is unsettled, and the amount and the temperature of the plastics of extruding from extrusion mouth 362 278 do not reach needed value.Be readily appreciated that,, make die arrangement 14 be subjected to injurious effects possibly if this moment is inferior the product quality that plastics 278 are added to compression moulding on the die arrangement 14, result's extrusion.Yet in the embodiment that illustrates, extruder 282 reach stable before, receiving member 376 is in the operating position, and the plastics 278 that provide to die arrangement 14 are provided.Therefore, can prevent bum pressing, and can effectively avoid die arrangement 14 is produced injurious effects.In addition, when the action of extruder 282 is stablized, but because some former figure requires to stop when die arrangement 14 feeds in raw material, for example, because some fault has taken place in rotation compression moulding device 2, make receiving member 376 be in the operating position, and the work that does not need to stop extruder just stoping add the work that in a single day plastics 278(has stopped extruder 282 in die arrangement 14, recover its work reach up to the action of extruder 282 stablize and need wait for a period of time).

Now, describe shearing device 348 in detail referring to Fig. 9 and Figure 18.Be fixed with the bearing block 422 and 424 that keeps at a certain distance away on (the L-R direction among Figure 18) at last rear each other on the supporting frame 292.Rely on these bearing blocks 422 and 424 rotating shafts 358 that shearing device 348 is installed, it can be rotated freely also can upwards move freely certain distance at last rear.Specifically referring to Figure 18, a circular port 426 that extend last back is arranged on the bearing block 422, bearing 428 is equipped with in the inside.Bearing 428 is installed on the cylindrical sleeve 430.Cover 430 is passed in rotating shaft 358.Rotating shaft 358 can anterior-posterior move freely with respect to cover 430, but prevents that by means of key 432 it from producing relative rotation with respect to cover 430.The circular port 434 that has fore-and-aft direction to extend on the bearing block 424 passes on the outer round surface of rotating shaft 358 of circular hole 434 bearing 436 is housed.Member 438 is fixed on the outer round surface of bearing 436.The diameter of member 438 outer cylinder surfaces and the internal diameter in hole 434 cooperate, and can be free to slide along fore-and-aft direction in hole 434.Stop up 423 and be screwed in the front end in hole 434 by screw thread, it has individual hole 440, can allow rotating shaft 358 pass.Between the rear end surface of obstruction 423 and the front end surface of member 438 spring assembly 425 being housed, can be compression helical spring.Spring assembly 425 leans on elastic force (left among Figure 18) mobile member 438 backward, so rotating shaft 358 also rotates backward.It must make the rotary cutter elasticity that is fixed on rotating shaft 358 front ends be pressed against on the template 352 of die head 286.

Obstruction 429 also is screwed in the rear end in the hole 434 on the bearing block 424 by screw thread, it has the hole 427 that can allow rotating shaft 358 pass.Be provided with a dish type movable member 433 in hole 434, it is in stops up 429 and be fixed between the bearing 436 in the rotating shaft 358, so that this disc-shaped component 433 can be free to slide along front-rear direction (the L-R direction among Figure 18).It has a hole 431 that can allow rotating shaft 358 pass.This mobile member 437 has constituted a device that makes the axle motion, so that axle 358 elastic reactions that overcome spring assembly 425 travel forward a little (dextrad of Figure 18).Referring to Figure 18 and 19, have gathering sill 435 at the upper wall of bearing block 424, bearing pin 437 passes gathering sill 435 and is fixed on the movable member 433.As shown in figure 19, gathering sill 435 has first position of engagement 435A and second position of engagement 435B, they rotating shaft 358 axially on separated by a distance, and axial vertical with rotating shaft 358, gathering sill 435 also has a skewed slot part 435C, and it extends between first and second position of engagement 435A and 435B.When the bearing pin that stretches out 437 on being fixed on removable part 433 in addition was in first position of engagement 435A of gathering sill 435, mobile member 433 was in off-position as shown in figure 18.In other words, movable member 433 is in the rear end of the bearing 436 in the rotating shaft 358, and the segment distance of being separated by.When catching the bearing pin 437 that stretches out, make it leave first position of engagement 435A, move to second position of engagement 435B by skewed slot part 435C, shown in double dot dash line among Figure 19, movable member 433 turn over certain angle and forward (dextrad among Figure 18) move a predetermined distance, so it is in the operating position.During mobile member 433 moved forward, it abutted against on the rear end surface of bearing 436, and therefore, the elastic force effect that bearing 436 and the rotating shaft 358 that is driven overcome spring assembly 425 also moves forward.Because the trend of second position of engagement 435B of gathering sill 435 is substantially perpendicular to the axial of rotating shaft 358, the elastic force effect of spring assembly 425 can not make mobile member 433 move backward from the operating position, and remains on the operating position.Therefore, rotating shaft 358 also remains on any position, front of position shown in Figure 18, and when rotating shaft 358 was positioned at this position, the rotary cutter 360 that is contained in rotating shaft 358 front ends also moved forward a bit from the surface of the template 352 of die head 286.Rotary cutter 360 can be dismantled and install so that check from the front end of rotating shaft 358 at an easy rate, keeps in repair and change like this.When catch be fixed on the removable in addition part 433 stretch out bearing pin 437 and when second position of engagement 435B turns back to first position of engagement 435A by skewed slot 435C, movable member 433 moves backward to off-position shown in Figure 180, rotating shaft 358 is moved backward by the elastic force effect of spring assembly 425, and the cutting knife 360 that is fixed on rotating shaft 358 front ends is pressed against by elastic force on the surface of template 352 of die head 286.

Be readily appreciated that referring to Figure 11 can more effectively cut off theplastics 278 that the extrusion mouth on thetemplate 352 362 is extruded fromdie head 286 in order to makerotary cutter 360, it well is very important that theblade 368 ofrotary cutter 360 contacts with the surface of template 352.For meeting this requirement, inshearing device 348, be pressed against the surface oftemplate 352 except makerotating shaft 358 passdrive cutting knife 360 elasticity backward byspring assembly 425, also used uniquemethod rotary cutter 360 to be installed in the front end ofrotating shaft 358.

Referring to Figure 20, at the front end of rotating shaft 358 through hole 442 is arranged, through hole 442 has a predetermined width dimensions W₁With than width dimensions W₁Big many axial dimension l₁It is the wall of the arcuate convex at center with axis 446 that the antetheca 444 of through hole 442 is one.Have individual along rotating shaft 358 axially extended slotting axis holes 448, its inner diameter d at the center of rotary cutter 360₂The outside diameter d of being a bit larger tham rotating shaft 358 front ends₁Rotary cutter 360 front ends also have a hole 450 that holds pin.This hole 450 that holds pin and slotting axis hole 448 are vertical and chip forward.The hole 450 width dimensions W that hold pin₂(that is, the internal diameter of semi-circular portions) thereafter is substantially equal to the width dimensions W of through hole 442₁Rotary cutter 360 usefulness bearing pins 452 are contained in the front end of rotating shaft 358.The outside diameter d of bearing pin 452₃Be substantially equal to the width dimensions W of through hole 442₁Therefore, also equal to hold the hole 450 width dimensions W of pin₂There are the part 453 under the arcuate concave and the antetheca 444 of through hole 442 arcuate convex to match at the front surface of bearing pin 452.If desired, the antetheca 444 of through hole 442 can be made the form under the arcuate concave, and the front surface of bearing pin 352 can be made the shape of arcuate convex.

Specifically, the front end thatrotary cutter 360 is contained inrotating shaft 358 carries out in the following manner.At first, the front end ofrotating shaft 358 is inserted in the slottingaxis hole 448 of rotary cutter 360.Then, bearingpin 452 is inserted on the throughhole 442 ofrotating shaft 358 and therotary cutter 360 and holds among thehole 450 of pin.As a result, by the resilient force ofspring assembly 425rotating shaft 358 is passed to the axle rear, simultaneously, cuttingknife 360 is compressed against on thetemplate 352, stops cuttingknife 360 to move to the axle rear.Therefore, antetheca 444 engagements of the arcuate convex of the arcuate concavelower part 453 of bearingpin 452 front surfaces and the throughhole 442 ofrotating shaft 358, and the rear wall engagement of holdingpin shaft hole 450 on the rear surface of bearingpin 452 and the rotary cutter 360.As a result,rotating shaft 358, bearingpin 452 androtary cutter 360 are clamped together by designed assembled state.

Also note that the following fact about above-mentioned assembly method.The first, because insert the inner diameter d of axis hole 448 on the rotary cutter 360₂The outside diameter d of being a bit larger tham rotating shaft 358 leading sections₁, rotary cutter 360 can with respect to rotating shaft 358 and pin 452 rotates freely and rotate in a predetermined angular range around the central axis 454 of pin 452, and (this angular range is by inner diameter d₂And outside diameter d₁Between poor Come determine).The second, the outside diameter d of being a bit larger tham rotating shaft 358 leading sections except the internal diameter of inserting axis hole 448₁Outside, the negative area 453 of the front surface of the front bulkhead 442 of through hole 442 and pin 452 cooperatively interacts with arc shape in the rotating shaft 358, and the axial dimension l of through hole 442₁Outside diameter d than pin 452₃Big is many.Therefore, pin 452 and cutting knife 360 can be with respect to rotating shaft 358 in predetermined angular ranges, and around central shaft 446, (being the axis of through hole 442 arcuate front 444) freely rotates.(by inner diameter d₂And outside diameter d₁Between poor Come determine).Like this, rotary cutter 360 with respect to rotating shaft 358 can around two be perpendicular to one another and with the axis of the axis normal of rotating shaft 358, promptly 454 and 446 freely rotate.Therefore, if template 352 surfaces cutting edge 368 very flat and cutting knife 360 is very straight, the error that no matter whether exists in fit on or manufacturing (for example, when rotating shaft 358 and the surperficial out of plumb with high-precision template 352), it is fully good that the surface of cutting blade 368 and template 352 contacts.

As top described referring to Figure 11, the cut-awayportions 354 that is shaped on thedie holder 350 ofdie head 286 is passed in therotating shaft 358 of shearing device 348.On dieholder 350, be processed with squeezingpassage 364, and theplastics 278 of fusing flow by this squeezing passage 364.So dieholder 350 reaches quite high temperature, thus,rotating shaft 358; Particularly its front end also reaches quite high temperature.The supporting construction of high like thistemperature countershaft 358 has deleterious effects.Simultaneously, heat passes to cuttingknife 360 from rotating shaft, and cuttingknife 360 may reach the high temperature that can not bear.In order to address this problem, in the embodiment that illustrates, adding in therotating shaft 358 ofshearing device 348 has cooling device.

Moreover, referring to Figure 18, a hole 456 is arranged in the rotating shaft 358, prolong forward from the rear end and be raised near the front end.On the other hand, be installed on the bracing frame 292 at the cooling medium common excretory duct 457 of rotating shaft 358 back locations, so that it also can freely move forward and backward (L-R direction among Figure 18).At cooling medium common excretory duct front end one outstanding coupling part 458 is arranged, the rearward end by the hole 456 in suitable jockey and the rotating shaft 358 links to each other, and can rotate relatively each other.In cooling medium common excretory duct 457, have one to introduce chamber 460 and discharge side 462.Discharge side 462 links by hole (not shown) in the outstanding coupling part 458 and the hole 456 in the rotating shaft 358.Rear end and the introduction chamber 460 of passing the pipe 465 in hole (not shown) in the outstanding coupling part 448 and the hole 456 in the rotating shaft 358 link to each other.Introduce chamber 460 and link to each other with cooling medium source (not shown) by introducing conduit 469, cooling medium can be the water or the cold water of room temperature state, introduces conduit 469, and the opening 467 that passes on the bracing frame 292 stretches out downwards.Passing the discharge pipe 471 that the opening 467 on the bracing frame 292 stretches out downwards links to each other with discharge side 462.Therefore, the cooling medium that provides from the supply station (not shown) is introduced into from introduction tube 469 and introduces chamber 460, flow into the front end that hole 456 in the rotating shaft 358 reaches rotating shaft 358 by managing 465.After this, cooling medium flows to the rear end in hole 456, discharges by discharge pipe 471.Above-mentioned cooling medium flows in rotating shaft 358 and has cooled off rotating shaft 358 well.

Referring to Fig. 9, the rotating shaft 358 of shearing device 348 links by driving jockey and drive source 52, the power drive system that will illustrate below jockey includes, drive source has dual-use function, drives rotation die arrangement 2 and drives shearing device 348 in the material feeder 4.The supporting walls 464 and 466 that stretches out is downwards arranged on the lower surface of bracing frame 292, and it separates each other at fore-and-aft direction (the L-R direction among Fig. 9).Power transmission shaft 468 is across being contained on supporting walls 464 and 466, and rotatable, and flywheel 470 is fixed on the front end (right-hand member among Fig. 9) of power transmission shaft 468.On the other hand, flywheel 472 is fixed on the cover 430 (Figure 18), and cover 430 is contained in the rotating shaft 358.The speed-governing belt 476 of circulation passes the opening 474 on the bracing frame 292, is enclosed within on flywheel 470 and 472.As a result, rotating shaft 358 drives with power transmission shaft 468 and has linked to each other.The second corner governor motion of being made a general reference by the 478 first angle position governor motions of being made a general reference and 480 is installed on the upper surface of horizontal base plate 316 of fixed pedestal 312.(the following detailed description first and second angle position governor motions 478 and 480).The 482 non-uniform rotation mechanisms of being made a general reference (following detailed description) are contained on the lower surface of horizontal base plate 316.Flywheel 486 is fixed on the output shaft 484 of the first angle position governor motion 478, and flywheel 488 is fixed on the afterbody (left end among Fig. 9) of power transmission shaft 468.Flywheel 488 is contained on the power transmission shaft 468 so that and power transmission shaft 468 as a unitary rotation.Yet power transmission shaft 468 can move forward and backward (the L-R direction among Fig. 9) with respect to flywheel 488.Supporting seat 490 is fixed on the upper surface of the first corner governor motion, 478 shells, and flywheel 488 links to each other with supporting seat 490, can not be last afterwards mobile so that its can freely rotate.As a result, placed restrictions on this flywheel 488 moving on fore-and-aft direction.Like this, when fluid pressure cylinder mechanism 322 drive supporting seat 292 front-rear directions (the L-R direction among Fig. 9) are mobile, power transmission shaft 468 moves with the flywheel 470 that is fixed on its front end also front-rear direction, but the flywheel 488 that is contained in power transmission shaft 468 rear ends can not move and be held on the position shown in the figure by front-rear direction.Circulation speed-governing belt 492 is enclosed within on flywheel 488 and 486, the result, the power transmission shaft 468 and the first angle position governor motion 478 output shaft 484 drive and link to each other.Flywheel 496 is fixed on the power shaft 494 of the first angle position governor motion 478, and flywheel 500 is fixed on the output shaft 498 of non-uniform rotation mechanism 482.Passing circulation that the opening 473 on the horizontal base plate 316 stretches out regulates belt 502 and is enclosed within on flywheel 496 and 500.As a result, the output shaft 498 of the power shaft 494 of the first corner governor motion 478 and non-uniform rotation mechanism 482 drives and links to each other.Flywheel 506 is fixed on the power shaft 504 of non-uniform rotation mechanism 482, and flywheel 510 is fixed on the output shaft 508 of the second angle position governor motion 480.The opening 512 that the speed-governing belt 514 of circulation passes horizontal base plate 316 is enclosed within on speed-regulating pulley 506 and 510.As a result, the walk around output shaft 508 of angle position adjusting mechanism 480 of the power shaft 504 and second of non-uniform rotation mechanism 482 drives and links to each other.The power shaft 516 of the second angle position governor motion 480 links to each other with drive source 52 by suitable drive system (not shown).The rotation of drive source 52 is by the second angle position governor motion 480 like this, and non-uniform rotation mechanism's 482, the first angle position governor motions 478 and power transmission shaft 468 are delivered on the turning cylinder 358, makes turning cylinder 358 and cutting knife 360 rotations that are contained in above it.

As shown in Figure 9,non-uniform rotation mechanism 482 has ashell 475 to be fixed on the lower surface of horizontal base plate 316.Output shaft 498 is contained on theshell 475 by bearing 477, and rotatable, andpower shaft 504 also is contained on theshell 475 by bearing 479, androtatable.Elliptic gear 481 is contained on theoutput shaft 498, andelliptic gear 483 is contained on the power shaft 504.Intermeshing a pair ofelliptic gear 481 and 483 converts the uniform rotation that is delivered topower shaft 504 to non-uniform rotation, and it is passed tooutput shaft 498.

Angular velocity omega referring to Fig. 9 and 21elliptic gears 481₂, be according to frank (flatnesses) e ofelliptic gear 481 and 483 and the angular speed W ofelliptic gear 483₁Come considers, the rotational angle theta ofelliptic gear 481₂Rotational angle theta with respect toelliptic gear 483₁As follows:

θ₂＝ 1/2 cos^-1( (k+cos2θ₁))/(1+kcos2θ₁)

K=(2e)/(1+e wherein²)

Here the angular velocity omega ofelliptic gear 481₂Uniform velocity ω withelliptic gear 483₁Ratio ω₂/ ω₁By under establish an equation definite:

$\frac{{\mathrm{<figure-callout\; label="\omega "\; filenames="85105550\_DRIMG1.png,85105550\_DRIMG15.png"\; state="\{\{state\}\}">\omega </figure-callout>}}_2}{{\omega }_1}=\frac{\sqrt{{\mathrm{1\; -<figure-callout\; label="k"\; filenames="85105550\_DRIMG1.png,85105550\_DRIMG15.png"\; state="\{\{state\}\}">k</figure-callout>}}^2}}{{\mathrm{1\; +<figure-callout\; label="kcos"\; filenames="85105550\_DRIMG1.png,85105550\_DRIMG15.png"\; state="\{\{state\}\}">k\; c\; o\; s</figure-callout>\; 2\; \theta }}_1}$

This proportionate relationship has been described in Figure 22.Rotatingshaft 358 and be contained inrotary cutter 360 above it like this with as shown in figure 22 non-at the uniform velocity angular speed rotation.

Should also be noted that the following fact about above-mentioned non-uniform rotation mechanism 482.Rotary cutter 360 cuts off that extrusion mouth 362(see Figure 11 from pressing mechanism 280) plastic material 278 extruded should see Fig. 1 with the die arrangement 14(the rotation compression mould device 2) rotational synchronization.Thereby rotary cutter 360 rotates the required time in a week and is determined uniquely by the rotating speed of the die arrangement 14 in the rotation compression mould device 2.On the other hand, the inventor's experience is pointed out, for mode is on demand cut off the plastic material of extruding 278 from extrusion mouth 362, importantly, regulates the angle speed ω of rotary cutter 360 in the time of inswept extrusion mouth 362₂Be transferred to a predetermined value, normally enough big value, however be appreciated that because above-mentioned non-uniform rotation mechanism 482 that from Figure 22 rotary cutter 360 crosses the angular velocity omega in time of extrusion mouth 362₂Get a reasonable numerical value between can be from the minimum of a value to the maximum.Usually get maximum ω₂, do not change rotary cutter 360 and circle the required time.Therefore do not destroy the rotation of die arrangement 14 and the synchronism between the cut-out plastic material 278, the angular velocity omega of cutting knife 360₂In the time of sweeping away extrusion mouth 362, can be transferred to needed

When if rotary cutter swept awayextrusion mouth 362, its angular velocity omega₂Get bigger value (normally getting peaked) and, should gradually reduce immediately, will obtain following advantage like this cutting off afterplastic material 278 swept away extrusion mouth 362.The angular velocity omega of rotary cutter₂Reduce immediately after cutting offplastics 278, theplastic material 278 of cutting-out is owing to inertia is tending towards keeping identical (the maximum ω normally of angular speed with rotary cutter 360₂), and the angular speed ofrotary cutter 360 reduces gradually, and therefore quickened to downcut the plastic material of Come and separating of rotary cutter.Can increase the rate of change of the angular speed ofrotary cutter 360 if desired with two couples or more elliptic gear Come.

In illustrating the embodiment of book, diearrangement 14 and downcutplastic materials 278 by cuttingknife 360 and regulate with respect to the strictness of the angle position ofpower shaft 516 byoutput shaft 508 by the second angleposition governor motion 480 in the rotationcompression moulding device 2 can keep synchronously by required mode formula.In addition, strictly regulate the angle position ofoutput shaft 484, make the angular velocity omega ofrotary cutter 360 wheninswept extrusion mouth 362 with respect topower shaft 494 by the first angleposition governor motion 478₂Be adjusted in minimum of a value ω in advance₁With maximum ω₂Between a suitable value, for example, for easy adjusting, the first and second angleposition governor motions 478 and 480 optimal forms are that the rotation that need not stop power shaft and output shaft just can be regulated the angle position of output shaft with respect to power shaft.

Describe the first spin angular position governor motion 478 in detail referring to Figure 23.The first angle position governor motion 478 that illustrates is made of shell or main body base 491 and end wall 493 and 495.Shell 491 is opened to (left-to-right direction among Figure 23) at last rear, and end wall 493 and 495 is separately fixed on two sides of main body base 491, and the hole of fore-and-aft direction is arranged respectively on end wall 493 and 495, comes on the straight line each other.Bearing 497 and 499 is placed in the hole.Back-up block 503 is fixed on the inner surface of end wall 493, and it has the hole 501 of front and back trend, and the front end of power shaft 494 promptly is supported on the bearing 497, can rotates, and stretch out forward in the hole 501 that it passes on the back-up block 503.The rear end that surpasses hole 501 output shafts 484 promptly is supported on the bearing 499 and can rotates and stretch out backward.Input gear 505 is fixed on the rear end of power shaft 494, and output gear 507 is fixed on the front end of output shaft 484.On the other hand, rotate other part 511 and be contained on the cylindrical of back-up block 503 by lining 509, and rotatable.To clearly illustrate, and rotate other part 511 and do not change when flat to have only when regulating output shaft 484 with respect to the angle position of power shaft 494 below, operating personnel just rotate it.The minor axis 513 that stretches out forward is inserted on the rotary body 511 securely, and input side power transmission gear 515 is contained on the minor axis 513 also rotatable.Input side power transmission gear 515 and 505 engagements of input gear.Be inserted with a minor axis 517 that stretches out backward from end wall 495 inner surfaces on end wall 495 securely, outlet side power transmission gear 520 is contained on the minor axis 517, and rotatable, outlet side power transmission gear 520 and output gear 507 engagements.Also have a sizable internal gear 522, it is enclosed in input side power transmission gear 515 and outlet side power transmission gear 520.Bearing 524 is placed between the internal circular surfaces of the outer round surface of internal gear 522 and main body base 491, therefore allows internal gear 522 to rotate with respect to main body base 491.The tooth of internal gear 522 internal circular surfaces and input side power transmission gear 515, outlet side power transmission gear 520 mesh simultaneously.

Referring to Figure 23 and 24 and the axle of power shaft 494 and output shaft 484 capwises 528 by means of bearing 524 and 526, be contained on the main body base 491, and rotation.Be formed with helical tooth 530 on the outer round surface of revolving part 511.Be fixed on the axle 528 with helical tooth 530 engaged worm 532.As shown in figure 24, an end of axle 528 stretches out from main body base 491, and manual operation turn-knob 534 is fixed on the end of stretching out of axle 528.Be bordering on columniform part 536 in addition and also be contained in this external part.Part 536 is contained on the axle 528 in addition, so that it can be moved with respect to axle 528 in the axial direction, but energy and axle 528 are as a unitary rotation.The in addition part 538 that is bordering on annular is fixed on the main body base 491, and a flange that radially stretches out inwardly 540 is arranged on the outer rim of other part 538, and is corresponding therewith, the flange 542 that has a radial outward to stretch out in the inner of other part 536.On the outer surface of part 536 external screw thread is arranged in addition, jam nut 544 is screwed on this external screw thread.Between locking nut 544 and other part 538, place a packing ring 546.The rotation lock nut makes it the right-hand motion in Figure 24, drives the right-hand rotation to Figure 24 of other part 536.As a result, in addition part 538 radially inwardly flange 540 be sandwiched in locking nut 544 and in addition between the flange outwardly 542 of part 536.Like this, stop the rotation of other part 536, therefore also stoped the rotation of axle 528.When the rotation of axle 528 is hindered and since worm screw 532 be fixed on the axle 528 on, and helical tooth 530 again with it the engagement, also just stoped the rotation of rotating other part 511.When the locking nut reverse rotation, it moves to the left of Figure 24, and in addition part 536 moves to left, and the result has been disengaged in radially inwardly the clamping of flange 540 of the flange 542 of radial outward and the part 538 in addition between the locking nut 544.By rotation manual operation turn-knob 534, axle 528 just can rotate.

The operation and the advantage of the following cutline first angle position governor motion 478.(when not regulatingoutput shaft 484 with respect to the angle position of power shaft 494) during the normal running, the effect of lockingnut 544 has stoped the rotation ofaxle 528, therefore, has also stoped the rotation of rotating other part 511.In this case, the rotation ofpower shaft 494 passes tointernal gear 522 throughinput gear 505 and input sidepower transmission gear 515, and the rotation ofinternal gear 522 passes tooutput shaft 484 through outlet sidepower transmission gear 520 and output gear 507.Therefore,output shaft 484 rotates.Because in the embodiment that illustrates,input gear 505 has the identical number of teeth with output gear 507.(therefore, input sidepower transmission gear 515 also has the identical number of teeth with outlet side power transmission gear 520),output shaft 484 andpower shaft 494 rotate with unequal angular velocity.Say for angleposition governor motion 478 Come if desired, suitably changeinput gear 505,output gear 507, the number of teeth of input sidepower transmission gear 515 and outlet sidepower transmission gear 520 just can realize reduction of speed or raising speed.

In the time will regulating output shaft 484 with respect to the angle position of power shaft 494, locking nut is with manually removing the obstructions that axle 528 rotates.Axle 528 rotates by handling manual operation turn-knob 534 then.As a result, rotated spinner member 511 through worm screw 532 and helical tooth 530.Input side power transmission gear 515 around minor axis 513 rotations also rotates around input gear 505.Such result temporarily quickens or has stoped the rotation of internal gear 522, therefore, temporarily quickens or stoped the rotation of outlet side power transmission gear 520 and output gear 507.Therefore, temporarily quicken or stoped the rotation of output shaft 484, changed the angle position of output shaft 484 with respect to power shaft 494.Output shaft 484 can illustrate from following example with respect to the degree of power shaft 494 angle positions change.The number of teeth that lets as assume that input gear 505 is Z_a, the number of teeth of input side power transmission gear 515 is Zb, the number of teeth of outlet side power transmission gear 520 is Z_c, the number of teeth of output gear 507 is Z_d, the number of teeth of internal gear 522 is Ze, and, (Ze)/3=Za=Zb=Zc=Zd.So, output shaft 484 increases or has reduced angle no with respect to corner ni, (that is, output shaft 484 changes with respect to the angle of power shaft 494).Provide by the following formula equation:

no＝± (Za+Ze)/(Zd) ·ni＝±4ni

(sign of no depends on the direction of rotation of rotating part 511).

The relational expression ofaxle 528 corners (nm) androtational parts 511 corner ni is got ni=(nm)/60, and then no is provided by following formula: no=± 4ni=(nm)/15.Therefore, for example, whenaxle 528 has rotated 30 °,output shaft 484 has changed 2 ° (=30/15) with respect to the angle position of power shaft 494.Therefore, the first angleposition governor motion 478 can suitably beregulated output shaft 484 with respect to the angle position ofpower shaft 494 and do not need to stop the rotation ofpower shaft 494 andoutput shaft 484.

The first angleposition governor motion 478 with above-mentioned is identical basically with respect to the second angleposition governor motion 490 ofpower shaft 516 angle positions to regulateoutput shaft 508, just no longer describes in detail here.
