The frame 1 has a control terminal (not shown in the figure). An extrusion rod 3 is slidably connected within the housing 2 and electrically connected to the control terminal. The extrusion rod 3 is used to extrude materials. A rotating frame 4 is detachably connected to the frame 1. Before using the device, the rotating frame 4 is opened, and materials are inserted into the housing 2. The rotating frame 4 is equipped with a cutting blade 401 and a fixed cylinder 5. The cutting blade 401 is electrically connected to the control terminal. The rotation of the cutting blade 401 cuts the extruded material into segments. The fixed cylinder 5 contains interconnected chambers 501 and channels 502. The vertical cross-section of the channel 502 is rectangular, used for shaping the material. The vertical cross-sectional shape of the channel 502 remains unchanged from its left to right end, and the vertical cross-sectional area of ​​the channel 502 gradually decreases from left to right to pressurize the moving material. The cutting blade 401 is attached to the right side of the fixed cylinder 5. A sliding frame is slidably connected within the chamber 501. 8. A limiting frame 6 is provided inside the fixed cylinder 5. The limiting frame 6 has several through holes 601, the diameter of which gradually decreases from left to right to pressurize the moving material. An elastic telescopic rod 7 is fixedly connected to the limiting frame 6. A sliding frame 8 is provided with a connecting hole 801. An electromagnet is provided inside the fixed cylinder 5 to attract the sliding frame 8 so that the connecting hole 801 moves to fit against the channel 502. The electromagnet is electrically connected to the control terminal. The telescopic part of the elastic telescopic rod 7 is located inside the connecting hole 801 so that the sliding frame 8 can slide on the telescopic part of the elastic telescopic rod 7. The diameter of the connecting hole 801 gradually decreases from left to right. A first elastic element, which is a compression spring, is fixedly connected between the sliding frame 8 and the fixed cylinder 5. The sum of the flow areas at the smallest diameter of all through holes 601 is greater than the maximum flow area of ​​the connecting hole 801. The minimum flow area of ​​the connecting hole 801 is greater than the maximum flow area of ​​the channel 502 so that the material is gradually pressurized as it moves to the right.

[0027] The specific working principle is as follows:

[0028] When the operator needs to use the device to produce the lower rubber pad, the operator opens the rotating frame 4, puts the material (rubber roll) into the shell 2, and then closes the rotating frame 4. The material is heated to soften, the control terminal is turned on to drive the extrusion rod 3 to move to the right to extrude the material, the material is softened and passes through all the through holes 601, the gas in the shell 2 is extruded to the connecting hole 801 through all the through holes 601, the gas extrusion sliding frame 8 moves to the right, the first elastic member of the sliding frame 8 is compressed, the resistance to the movement of the material on the left side of the sliding frame 8 is increased, after the sliding frame 8 moves to the right and loses contact with the telescopic part of the elastic telescopic rod 7, the gas is discharged to the cavity 501 through the connecting hole 801, and finally the gas is discharged through the channel 502. When the material moves to contact the sliding frame 8, the operator turns on the electromagnet through the control terminal, the electromagnet attracts the sliding frame 8 to move to the right, and the material moves to the right through the connecting hole 801 into the channel 502 (the operator can also turn on the electromagnet intermittently to make the first elastic member and the electromagnet drive the sliding frame 8 to move back and forth, and the sliding frame 8 extrudes the material on the left side back and forth to further extrude the gas in the material to the connecting hole 801), the resistance to the movement of the material on the left side of the sliding frame 8 is increased through the blocking of the sliding frame 8, the softened material between the limiting frame 6 and the sliding frame 8 is gradually compacted to reduce the amount of gas in the material, so that the pore volume in the rubber pad after production is reduced, thereby ensuring the uniformity of the density and quality of the rubber pad and improving the quality of the rubber pad after production.

[0029] In the process of moving the softened material to the right by the extrusion rod 3, the material passes through all the through holes 601, the connecting hole 801 and the channel 502 in turn, the operator turns on the cutting knife 401 through the control terminal, and the material discharged from the channel 502 is cut into several rectangular rubber pads by the cutting knife 401. In the process of passing through the through holes 601, the connecting hole 801 and the channel 502, the space for the material to flow gradually decreases to pressurize the movement of the material and make the material more compact, thereby ensuring the quality of the extruded rubber pad.

[0030] When the material is cut into several rectangular rubber pads by the cutting knife 401, the operator turns off the cutting knife 401 through the control terminal, moves the extrusion rod 3 to the left to reset, and then turns off the extrusion rod 3 and the electromagnet through the control terminal. The electromagnet no longer attracts the sliding frame 8, the first elastic member rebounds and drives the sliding frame 8 to reset, and then the rotating frame 4 is rotated to open for cleaning the residual material in the fixed cylinder 5 and the shell 2.

[0033] As shown in the figure, Figure 6 As shown in the figure, Figure 7 As shown, the limiting frame 6 is slidably connected with a plurality of sliding plates 12 distributed at intervals, when the limiting frame 6 rotates, the limiting frame 6 is used to drive all the sliding plates 12 to rotate, the sliding plates 12 rub and extrude the edges of the material to crush the material, and the second elastic member is fixedly connected between the sliding plates 12 and the limiting frame 6, wherein the second elastic member is a compression spring, during the process that the extrusion rod 3 pushes the material to move from left to right, the operator opens the motor 9 through the control terminal, the output shaft of the motor 9 drives the limiting frame 6 to rotate through the gear 10 and the gear ring 11, all the through holes 601 rotate, so that the material passing through all the through holes 601 is uniformly mixed, the amount of pores in the material is reduced, and the limiting frame 6 drives all the sliding plates 12 to rotate, all the sliding plates 12 crush the softened edges of the material, further improving the uniformity of the softened material, thereby improving the quality of the rubber pad after extrusion, and when the extrusion rod 3 moves to the right and abuts against the limiting frame 6, the motor 9 is turned off through the control terminal.
