The blow molding mechanism includes compressor 7, gas blow pipe 8, sealing block 9,10, two springs 11 of movable plate and two cylinders12, two cylinders 12 are located at the two sides of compressor 7, and the cylinder body and compressor 7 of the cylinder 12 are each attached to lifting platform 4Top, the top of the gas bar of the cylinder 12 and movable plate 10 are sequentially connected, and the movable plate 10 and sealing block 9 are set in and blowOn tracheae 8, the gas blow pipe 8 is tightly connected with sealing block 9, and the bottom end of the gas blow pipe 8 is fixed on the top of compressor 7, instituteIt states gas blow pipe 8 to be connected to compressor 7, two springs 11 are located at the two sides of gas blow pipe 8, and the shape of the sealing block 9 is circleCylindricality is bored, the top of movable plate 10 is arranged in the underrun spring 11 of the sealing block 9, and the compressor 7 and cylinder 12 are equalIt is electrically connected with PLC.
When manufacturing plastic barrel using the blow moulding equipment, producers operate equipment operation by controller 2, by movingTwo molds 5 of mechanism controls are mobile, and after two molds 5 are separated, the plastic parison of softening is tipped upside down on gas blow pipe 8 from top to downOn, so that the top of the apical support parison of escape pipe, consequently facilitating placing parison, then mobile mechanism drives two molds 5It is mobile, so that elevating mechanism starting drives lifting platform 4 to move up, so that gas blow pipe 8 drives after two molds 5 are close to each otherAfter parison protrudes between the type chamber of two molds 5 formation, the top of lifting platform 4, PLC controls cylinder 12 and starts, by cylinder 12Gas bar drive movable plate 10 move up so that movable plate 10 by spring 11 drive sealing block 9 move up, sealing block 9 withThe distance of mold 5 is gradually reduced, and with gradually moving for sealing block 9, the inner wall of parison is gradually extruded in mold 5 by sealing block 9On, spring 11 is compressed at this time, upward support force is generated to sealing block 9, so that the inside of 9 extruded parison of sealing block, thusRealize the fixation and sealing to mold 5, then PLC controls compressor 7 and starts, and introduces external air and is compressed, by blowingTracheae 8 is blown into inside parison, is extruded in parison by inflation on 5 inner wall of mold, can be prepared by moulding by being cooled and shaped laterCharging basket, then mobile mechanism drives two molds 5 to separate, and elevating mechanism starting drives lifting platform 4 to move down, so that moldingPlastic barrel move down, personnel easy to produce take away production complete plastic barrel.
As shown in Figure 1, the mobile mechanism includes first motor 13 and two moving assemblies, the first motor 13 is fixedIn the lower section of crossbeam 3, the first motor 13 is electrically connected with PLC, and two moving assemblies are located at the two sides of first motor 13,The moving assembly and mold 5 correspond, and the moving assembly includes screw rod 14, translational block 15 and sliding block 16, and described firstOne end of motor 13 and screw rod 14 is sequentially connected, and the other end of the screw rod 14 is arranged in translational block 15, the translational block 15With the junction of screw rod 14 be equipped with the matched screw thread of screw rod 14, the sliding block 16 is fixed on the top of translational block 15, describedSliding block 16 is set on crossbeam 3, and the mold 5 is fixed on the lower section of translational block 15.
PLC controls first motor 13 and starts, and the screw rod 14 of two sides is driven to rotate, and screw rod 14 is by threaded function in translational blockOn 15, it is set on the crossbeam 3 by the fixed support of two struts 6 due to the sliding block 16 being fixedly connected with translational block 15, thus solidThe moving direction of translational block 15 is determined, so that casing is moved along the axis of screw rod 14, and then has driven mold 5 and movedIt is dynamic.
Preferably, in order to drive lifting platform 4 to carry out lifting moving, the elevating mechanism includes the second motor 17, firstConnecting rod 18 and second connecting rod 19, second motor 17 are fixed on the top of pedestal 1, and second motor 17 is electrically connected with PLC,Second motor 17 is sequentially connected with first connecting rod 18, and the first connecting rod 18 is hinged by second connecting rod 19 and lifting platform 4,The lifting platform 4 is set on strut 6.
PLC controls the starting of the second motor 17, and first connecting rod 18 is driven to rotate, and first connecting rod 18 is acted on by second connecting rod 19On lifting platform 4, so that lifting platform 4 carries out lifting moving along the axis of strut 6.
Preferably, being equipped with gas in the cylinder body of the cylinder 12 to detect whether sealing block 9 completes sealing to parisonPressure meter 20, the barometer 20 is electrically connected with PLC.After cylinder 12 starts, the air pressure in cylinder 12 is detected using barometer 20,And barometric information is passed into PLC, continue to increase air in the cylinder body of cylinder 12, the bar that makes to bring about the desired sensation drives movable plate 10 to moving upIt is dynamic, to support sealing block 9 to move up, when sealing block 9 drives parison to be extruded between two molds 5, due to cylinder 12The intracorporal capacity of cylinder be not further added by so that the intracorporal air pressure of the cylinder of cylinder 12 increased dramatically, PLC detects that barometric information increasesGreatly, so that it is determined that sealing block 9 is completed fixes to the sealing of parison, it is out of service to control cylinder 12 by PLC at this time.
Preferably, for the ease of detecting the position of movable plate 10, the top of the movable plate 10 is equipped with range sensor21, the range sensor 21 is electrically connected with PLC.The distance between movable plate 10 and mold 5 are detected using range sensor 21,And range data is passed into PLC, since the height and position of mold 5 immobilizes, PLC can determine shifting by range dataThe position of movable plate 10 carries out lifting moving convenient for accurate control movable plate 10.
Preferably, parison ruptures in order to prevent, the top of the gas blow pipe 8 is equipped with several brackets 22, the bracket 22It is circumferentially evenly distributed on the periphery of gas blow pipe 8, one end of the separate gas blow pipe 8 of the bracket 22 is equipped with supporting block 23, describedThe shape of supporting block 23 is spherical shape, and the height of the supporting block 23 is greater than the height on the top of gas blow pipe 8.Using bracket 22 to ballThe supporting block 23 of shape is supported, so that the height of supporting block 23 is higher than the top of gas blow pipe 8, parison is covered from top to down and is being blownWhen on tracheae 8, spherical supporting block 23 is contacted with parison, avoids the parison rupture of softening, when guaranteeing that gas blow pipe 8 is blown, parisonCompressed air impact and inflation abuts against on the inner wall of mold 5.
When the blow moulding equipment carries out plastic barrel production, parison is covered from top to down on gas blow pipe 8, to facilitate parisonPlacement, then moving assembly control two movements close to each other of mold 5, elevating mechanism drive lifting platform 4 move up so thatGas blow pipe 8 drives parison to extend upwardly between the type chamber of two molds 5 formation, then drives movable plate 10 to moving up from cylinder 12It is dynamic, so that sealing block 9 moves up, parison extruding is fixed between two molds 5, to realize the fixation of parison and closeEnvelope, compressor 7 are blown by gas blow pipe 8 into parison, abut against parison on 5 inner wall of mold by inflation, after being cooled down, i.e.,Plastic barrel can be made, then moving assembly separates two molds 5, and elevating mechanism drives lifting platform 4 to move down, thus convenientPeople remove the plastic barrel on gas blow pipe 8.
Compared with prior art, which passes through air blowingPipe 8 is set up, and is facilitated and is covered parison on parison from the top down, then makes sealing block 9 by parison by being blow molded mechanismInner wall is extruded between two molds 5, the fixing seal to parison is realized, then blow into parison by compressor 7, in parisonIt can be cooled and shaped after inflation, to ensure that the smooth production of plastic barrel, improve the practicability of the blow moulding equipment.
