Ferrite core (or soft ferrite) is a high-frequency magnetic conductive material (the principle is the same as silicon steel sheet, but only used in high-frequency environment), mainly used as high-frequency transformer (such as switch power supply, line output transformer, etc.), high-frequency magnetic ring (for anti-interference), etc., to increase magnetic conductivity and improve inductance quality factor, and used in the transformer.

At present, the common method for producing ferrite cores is powder metallurgy, i.e. dry forming, and the equipment used is called a core press equipment, or a core press, or powder metallurgy equipment. The magnetic core press can make powder preliminarily formed under strong pressure, and then subsequent sintering, grinding and sorting packaging are carried out, so that finished ferrite magnetic cores are produced.

When the ferrite core is produced, the ferrite core is usually E-shaped, F-shaped or PQ-shaped and is produced with an opening facing downwards; the subsequent process also needs to stack the pressed and formed green bodies, then the green bodies are stacked and sintered (the stacking and sintering efficiency is high), and meanwhile, in order to prevent the green bodies from being damaged, the green bodies of the magnetic cores need to be placed or placed with the openings facing upwards; however, the current method for turning over the green body is manual turning, or turning 180 degrees of a sliding rail (with a U-shaped opening) to carry out reverse side, but the green body is easy to damage in practice no matter manual turning or sliding rail turning, and the production effect is poor.

The magnetic core press-based conveying transfer unit provided by the invention is characterized in that after a magnetic core green body is produced, the magnetic core green body is transferred to theconveyor belt 9 positioned at thefirst turning roller 2, then a driving mechanism (not shown in the figure, preferably a speed reducing motor, is connected with one or more turning rollers, and then drives the turning roller(s) to rotate so as to drive theconveyor belt 9 and all the turning rollers to rotate) to drive theconveyor belt 9 to move, and the green body is transferred to thesecond turning roller 3, at the moment, a positioning magnet 10 (preferably an artificial strong magnet, which can generate a large enough suction force on the green body and prevent the green body from sliding or falling off from theconveyor belt 9, and can also generate strong magnetism by selecting an electromagnetic mode according to actual conditions) plays a role in attracting the green body, so that even if theconveyor belt 9 positioned between thesecond turning roller 3 and thethird turning roller 4 is inclined downwards, the position of the green compact is also stabilized by the attraction of thepositioning magnet 10.

With the rotation of the conveyor belt 9, the green body is transferred to the third turning roll 4 and moves to the lower side of the third turning roll 4, wherein the height difference (i.e. the set distance) between the conveyor belt 9 between the third turning roll 4 and the fourth turning roll 5 and the conveyor belt 9 between the fifth turning roll 6 and the sixth turning roll 7 is enough for the green body to make a turn, and the green body is slightly higher than the conveyor belt 9 below the green body after the turn is completed; the magnetic attraction of the positioning part 10a is large, so that the green bodies can be firmly fixed, and the green bodies are prevented from sliding or falling off from the conveyor belt 9, but the magnetic attraction of the transition part 10b is small, and the magnetic attraction applied to the green bodies is slightly larger than the gravity of the green bodies, so that with the movement of the conveyor belt 9, after the green bodies move to the outer side below the transition part 10b, the green bodies fall onto the conveyor belt 9 below due to the small magnetic attraction applied by the transition part 10b, and then move in the opposite direction with the conveyor belt 9, namely move in the direction of the sixth turning roller 7, wherein with the small magnetic attraction of the transition part 10b and the certain height difference between the green bodies and the transition part 10b, the green bodies are not attracted by the transition part 10b again in the process of moving towards the sixth turning roller 7; the conveyer belt 9 is preferred that static friction is big simultaneously, but softer material, when the transport unburned bricks that like this can be more stable moves about, when the unburned bricks fell down, can also be fine prevent that the unburned bricks from taking place to damage.

When the green bodies fall down from the upper conveyingbelt 9 to the lower conveyingbelt 9, the angle of the green bodies is turned by 180 degrees relative to the initial position, namely, the green bodies transferred from thesixth steering roller 7 are in a turned state, so that the green bodies do not need to be turned manually or by a sliding rail and the like, the labor cost is reduced, and meanwhile, the green bodies are softly carried out in the whole transfer process, so that the green bodies can be prevented from being damaged, and the yield is improved. Not so anxious, all turn to the rotation of roller can only need to have a actuating mechanism (be driving motor promptly, or driving motor adds chain or belt), consequently also make manufacturing cost lower, and all turn to the projection of roller in vertical direction almost is in same straight line, so can occupy better space, and the operation of each structure is only for setting up the position rotation simultaneously, also is difficult for producing the interact with external structure or workman, and the result of use is better.

In this application, the term "set distance", "set gap" or other similar terms, which is actually expressed, means that the two structures are not in a state of mutual contact, but the actual distance needs to be determined according to the actual situation, such as "set distance" needs to be determined according to the width and thickness of the green body, and "set gap" mainly means that the distance between the two structures is very small, such as 0.5cm or 0.3cm, and is not limited too much.

When the green bodies still move at the top of theconveyor belt 9, the green bodies are firstly under the action of the stabilizingpart 10c, the stabilizingpart 10c can adsorb and cling the green bodies to theconveyor belt 9 when the green bodies are turned over, and meanwhile, the inertial acting force of the green bodies when the green bodies are turned over at thesecond turning roller 3 can be borne, so that the position stability of the green bodies is improved; meanwhile, during the turning process of the green body, although the distance between the stabilizingpart 10c and the green body is long, the connection tightness between the green body and the conveyingbelt 9 can be improved to a certain extent, so that the stability of conveying the green body is further ensured.

Although the first and second avoidinggrooves 11 and 12 are respectively formed in the middle of the second andthird steering rollers 3 and 4, theconveyor belt 9 can be normally driven to move at both ends of the second andthird steering rollers 3 and 4, and theconveyor belt 9 can be properly supported by the first and second connectingportions 10d and 10e, so that theconveyor belt 9 can stably rotate and convey green bodies; meanwhile, the first connectingportion 10d and the second connectingportion 10e are also magnetic, and both ends of the first connectingportion 10d are respectively connected to thepositioning portion 10a and the stabilizingportion 10c, and both ends of the second connectingportion 10e are respectively connected to thepositioning portion 10a and thetransition portion 10b, so that thepositioning magnet 10 is formed as a whole by the first connectingportion 10d and the second connectingportion 10e, and more preferably, is in a ring shape in the drawings. Because first connectingportion 10d and second connectingportion 10e also can both play absorbent effect to the unburned bricks, and first connectingportion 10d and second connectingportion 10e are all the upset that is located the unburned bricks or the position department that turns to, so set up the improvement that first connectingportion 10d and second connectingportion 10e can also be better here or guarantee the position or the motion stability of unburned bricks, guaranteed that the process of shifting and upset unburned bricks can stably go on. Wherein the widths of thepositioning portion 10a, thetransition portion 10b and the stabilizingportion 10c are large, it is possible to further secure the stability of the green sheet position where the second andthird steering rollers 3 and 4 are absent.

Wherein when the green compact has been overturned 180 degrees to withtransition portion 10b separation (or dislocation) after, the green compact can drop to be located on theconveyer belt 9 of stabilizingmagnet 13 top at first, then carry out the conveying along withconveyer belt 9, because the distance between green compact and stabilizingmagnet 13 is close at this moment, and the distance betweentransition portion 10b is far away, add the weight of green compact oneself for the green compact only can open the mouth upwards (the state of having overturned 180 degrees) transmit, prevented that the green compact from being sucked up bytransition portion 10b once more. At the same time, the projection of the end of thetransition part 10b remote from thepositioning part 10a in the vertical direction is located on the stabilizingmagnet 13, so that it is ensured that both the green body can fall onto theconveyor belt 9 directly above the stabilizingmagnet 13 and the stabilizingmagnet 13 can ensure that the green body is conveyed to the outside of thetransition part 10 b.

As the service time increases, theconveyor belt 9 needs to be tensioned after the length of the total length of theconveyor belt 9 is increased, wherein the tensioning mode is as follows:

taking fig. 8 as an example of the specification, the operatingring 24 is first driven to the left, and theoperating ring 24 drives the operating and stabilizingteeth 18 to move to the left until the stabilizingteeth 18 are separated from thefitting grooves 21, and the stabilizingspring 20 is further compressed, in the process, the stabilizingbodies 19 on the stabilizingteeth 18 slide in the stabilizinggrooves 17. Then, the adjustingscrew rod 16 is rotated by the hand wheel, and two ends of the adjustingscrew rod 16 are rotatably connected with thebracket 1, so that the self position of the adjustingscrew rod 16 does not horizontally move and can only be carried out, and meanwhile, the stabilizingbody 19, the stabilizingteeth 18, the operation handle and the operationconvex ring 23 are also driven to rotate. The adjustingscrew 16 can drive the adjustingblock 15 to move towards the right in the rotating process until theconveyor belt 9 is tensioned, the operatingring 24 is released, the stabilizingteeth 18 move towards the matchinggroove 21 under the elastic acting force of the stabilizingspring 20 until the stabilizingteeth 18 are finally clamped (or meshed) in the matchinggroove 21, and theconveyor belt 9 is tensioned simply and conveniently.

During actual operation, after the position of the adjustingblock 15 is adjusted, the stabilizingteeth 18 may not be completely aligned with the stabilizingteeth 18, and then the adjustingscrew rod 16 needs to be finely adjusted, so that the stabilizingteeth 18 can be clamped into the matchinggroove 21, because theconveyor belt 9 has certain deformation and the tensioning is also a range value, and the number of teeth around the stabilizingteeth 18 is dense, the tensioning and subsequent normal use of theconveyor belt 9 are not affected after fine adjustment, and meanwhile, the stabilizingteeth 18 can also be clamped into the matchinggroove 21; because the stabilizingteeth 18 are clamped in the matchinggrooves 21 of the adjustingscrew rod 16 through the stabilizingbodies 19, the adjustingscrew rod 16 and the adjustingblock 15 cannot rotate relatively, namely the adjustingblock 15 limits the rotation of the adjustingscrew rod 16, so that the position of the adjustingscrew rod 16 is stable, and the position of the adjustingblock 15 is also stable, the tensioning effect of theconveyor belt 9 is ensured, and the adjustingblock 15 is prevented from moving towards the left spontaneously.

In the use process, the stabilizingspring 20 is continuously in a compressed state, so that the stabilizingteeth 18 can be prevented from being disengaged from the matchinggrooves 21, and meanwhile, when the adjustingscrew rod 16 is rotated, fingers of an operator can act on the operatingconvex ring 23 through the operatingring 24, so that relative friction between the rotation of the operatingconvex ring 23 and the fingers of a worker can be prevented, and the adjustment convenience and the use comfort are improved. The operatingring 23 and theoperating ring 24 are both raised at the end of the operatingbarrel 22, so that the operatingring 24 and theoperating ring 23 provide a point for a finger to apply a force to drive the stabilizingteeth 18.

When green bodies with different thicknesses are transferred, the height difference between theconveyor belt 9 between thethird steering roller 4 and thefourth steering roller 5 and theconveyor belt 9 between thefifth steering roller 6 and thesixth steering roller 7 needs to be adjusted to adapt to the green bodies with different thicknesses, wherein only the heights of thefifth steering roller 6 and thesixth steering roller 7 need to be adjusted during adjustment, and after the adjustment is completed, the top of thefifth steering roller 6 is still higher than that of thefourth steering roller 5, while the bottom of thefifth steering roller 6 is still as high as that of thesixth steering roller 7, so that the conveying process can be stably carried out.

When the fifth steering roller 6 is adjusted, firstly, the top of the fine adjustment screw 27 is rotated, and the bottom of the fine adjustment screw 27 is separated from the bottom of the fine adjustment groove 26, and then a larger number of fine adjustment pieces 28 or a reduced number of fine adjustment pieces 28 can be sleeved on the bottom of the fine adjustment screw 27; when the number of the fine tuning pieces 28 reaches a proper value, the fine tuning screw 27 is rotated to enable the fine tuning screw 27 to move downwards, and after the bottom of the fine tuning screw 27 is in threaded connection with the bottom of the fine tuning groove 26, the fine tuning screw 27 is continuously rotated downwards and moved to enable all the fine tuning pieces 28 to be in a tightly superposed state, and at the moment, the height difference between the bottom of the fine tuning block 25 and the bottom of the fine tuning groove 26 is the sum of the thicknesses of the fine tuning pieces 28; wherein the fifth steering roller 6 is rotatably connected to the middle of the fine adjustment block 25, so that when the position adjustment of the fine adjustment block 25 is completed, the position of the fifth steering roller 6 is fixed, and the fifth steering roller 6 can normally rotate and convey the conveyor belt 9.

When the height of thesixth turning roll 7 is adjusted, theadaptive screw 32 is firstly loosened, then thefine adjustment plate 30 can be moved upwards or downwards, after thefine adjustment plate 30 moves to a proper height along thefine adjustment hole 29, theadaptive screw 32 passes through the matchinghole 33 opposite to theadaptive hole 31 and then is in threaded connection with the corresponding threaded hole on theadjustment block 15, wherein the threaded hole on theadjustment block 15 corresponding to thematching hole 33 is at the same height, and theadaptive hole 31 is in a horizontal long strip shape, so that even if the height of thefine adjustment plate 30 is adjusted, two matchingholes 33 on eachfine adjustment plate 30 are always opposite to theadaptive hole 31, and therefore, all the matching holes 33 can be passed through by adjusting the position of theadaptive screw 32.

The reason why the two groups of matchingholes 33 are arranged in a shape like a Chinese character 'ji' is that the thickness variation of different green bodies is small, so that if all the matching holes 33 are vertically arranged, some matching holes 33 are possibly directly communicated, and thus the matching holes 33 can be mutually independent in a mode of dislocating the matching holes 33, so that the structural strength of the adjusting plate is ensured. It should also be understood that even if the threaded holes in theadjustment block 15 for corresponding engagement holes 33 are open, the effect is not significant because theadjustment block 15 is a single piece that is strong enough even if the threaded holes are open.

In actual use, theconveyor belt 9 is usually tensioned independently, namely by an adjustingscrew 16 and the like; or after the positions of the fifth andsixth steering rollers 6 and 7 are adjusted, the length of theconveyor belt 9 needs to be tensioned or loosened (the loosening is convenient for adjusting the heights of the fifth andsixth steering rollers 6 and 7) by the adjustingscrew rod 16. Meanwhile, the thickness (smaller) of each of thefine adjustment pieces 28 is equal to the height difference of the adjacent fitting holes 33, so that if onefine adjustment piece 28 is added, thefine adjustment plate 30 needs to be adjusted upward so that theaccommodating screw 32 passes through thefitting hole 33 located at the lower stage.

When the unburned bricks were in the activity onconveyer belt 9, it received the spacing of theguard plate 34 of both sides, can improve the positional stability of unburned bricks, and the limiting plate can also play the effect of rectifying to the unburned bricks simultaneously for better back that the unburned bricks can be put is followed up taking. Wherein thefeed opening 35 is mainly used for the green body to be placed, it can be carried out more easily, for example by a robot transfer (with electromagnets on the robot, the powder metallurgy in the green body is transferred to theconveyor belt 9 on the press by suction, and the green body is placed on theconveyor belt 9 by switching off the power supply after placing). Meanwhile, thedischarge opening 36 is convenient for the overturned green body to be transferred to other structures for subsequent processing, for example, an air cylinder is arranged on one side of thedischarge opening 36, a horizontal push plate is arranged on a piston rod of the air cylinder, and a support plate is arranged on the other side of the air cylinder; after the green body has moved to thedischarge opening 36, the cylinder and push plate push the green body onto the support plate for subsequent machining or treatment. It should also be understood that the structure for transferring the green body onto theconveyor belt 9 and the structure for transferring the green body off theconveyor belt 9 are not structures claimed in the present application and will not be described in detail herein.
