[0014] The beneficial effects of the present invention are as follows: 1. In the present invention, through the arranged processing seat, bottom table, Z-shaped seat, top plate, side seat, suction box, air pump, exhaust box and exhaust port, after placing the plastic, slicing operation is carried out. The cutting assembly cuts the plastic into plastics with uniform specifications. During this process, the suction box filters the external gas and transports it to the air pump for pressurization, and then discharges it through the exhaust port. The discharged gas blows the cut plastic to remove the debris adhering to the surface of the plastic, and at the same time assists the plastic to flatten and fall off, improving the slicing effect; the device uses the pressurized gas to blow the slicing process base, which can remove the debris adhering to the surface of the plastic, improve the quality of the plastic after forming, and at the same time assist the plastic to flatten and fall off, avoiding the adhesion of the plastic and affecting the subsequent cutting process.
[0015] 2. In the present invention, through the arranged cutting assembly, during the cutting process, the functional motor drives the cam to rotate, so that the driving plate on the Z-shaped seat changes its position as the cam presses. After the position of the cam changes, under the reverse acting force of the return spring, the driving plate returns to its original position. With the high-speed rotation of the cam, the two driving plates drive the cutting wire to do reciprocating up and down movements, so as to cut the plastic; the reciprocating movement state of the driving plate is realized by using the cam and the return spring, so that the cutting wire is in high-speed movement, improving the cutting effect of the cutting wire.
[0016] 3. In the present invention, through the arranged annular sliding seat, ring seat, connecting rod, sleeve gear, rotating motor and rotating gear, the rotating motor drives the ring seat to rotate on the bottom table, so as to realize the circular motion of each cutting assembly around the bottom table, realizing the rotary cutting of multiple plastics; by using the annular sliding seat, while ensuring the circular motion of the Z-shaped seat, the overall stability of the cutting assembly is improved, avoiding the excessive shaking of the cutting assembly and causing the non-uniform specifications of the sliced plastics.
[0017] 4. Through the provided conveying component and driving component, the plastic is placed into the bottom box. After the top cover is covered and fixed, the driving motor drives the I-shaped gear to rotate, so that the conveying gear meshes with the tooth bar to drive the tooth bar to move. During the movement of the tooth bar, the push plate pushes the plastic to move outwards, so that the cutting component cuts the plastic. During the movement of the plastic, the heating pads on the side plates will heat the plastic to improve the slicing efficiency. The plastic is fixed by using the method of turning over and covering and pressing the conveying cover plate, so as to ensure the stability of the plastic during the cutting process; the heating pads can preheat the plastic, which is convenient for subsequent cutting operations. The upper conveying cylinder and the lower conveying cylinder can ensure the smooth movement of the plastic in the conveying component.
[0018] 5. Through the provided shaft rod, movable socket, push rod, roller head, sleeve box, top seat, hydraulic rod, pulling socket and limit spring, after the plastic is placed, the hydraulic rod drives the movable socket to move downwards. The roller head on the push rod moves in the sleeve box and exerts pressure on the conveying cover plate. As the descending distance of the movable socket increases, the conveying cover plate turns over to contact the plastic and applies pressure to fix the plastic; the turning over of the conveying cover plate is realized by using the push rod and the roller head, which is convenient for the placement and fixation of the plastic and improves the convenience of using the device; the pulling socket and the limit spring can assist the reset of the push rod and play a buffering role at the same time.

[0025] Furthermore, as Figure 1 、 Figure 4 and Figure 6As shown in the figure, the upper outer wall of the bottom platform 2 is bolted with a bottom box 22.

[0026] Furthermore, as Figure 4 , Figure 5 and Figure 7 shown, the driving component includes four rack bars 33, four rod sleeves 34 and a driving motor 35. Two rod sleeves 34 are bolted to the upper outer wall of the bottom box 22, and the other two rod sleeves 34 are bolted to the lower outer wall of the top cover 23. The four rack bars 33 are respectively slidably connected to the inner walls of the four rod sleeves 34. And one end of each of the four rack bars 33 is bolted with a backing plate 32. On the other outer wall of the backing plate 32, a push plate 31 is bolted. The four push plates 31 are respectively located inside the four conveying components.

The two conveying gears 38 are respectively meshed with the tooth grooves of the two rack bars 33.
[0027] Furthermore, as Figure 5 and Figure 8As shown in the figure, a shaft rod 39 is connected to the outer wall of the upper side of the top cover 23 by bolts. An active socket 40 is slidably connected to the outside of the shaft rod 39. Four rectangular grooves are arranged on the active socket 40 at equal circumferential intervals. A push rod 41 is rotatably connected between the inner walls on both sides of the rectangular groove. Round holes are formed at the other ends of the push rods 41. A roller head 42 is rotatably connected to the inner wall of the round hole. And socket boxes 43 are connected to the outer wall of the upper side of the conveying cover plate 29 by bolts. The roller head 42 is in rolling connection with the inner wall of the socket box 43. The push rod 41 and the roller head 42 are used to realize the flipping of the conveying cover plate 29, so as to facilitate the placement and fixation of plastics and improve the convenience of using the device; The top end of the shaft rod 39 is connected to a top seat 44 by bolts.

The driving socket 46 and the limiting springs 47 can assist the push rod 41 to reset and play a buffering role at the same time.
[0028] Working principle: Put the plastic into the bottom box 22. The hydraulic rod 45 drives the active socket 40 to move downward. The roller head 42 on the push rod 41 moves in the socket box 43 and applies pressure to the conveying cover plate 29. As the downward movement distance of the active socket 40 increases, the conveying cover plate 29 flips to contact the plastic and applies pressure, and the plastic is fixed. Subsequently, the driving motor 35 drives the I-shaped gear 36 to rotate, so that the conveying gear 38 meshes with the rack 33 to drive the rack 33 to move. During the movement of the rack 33, the push plate 31 pushes the plastic to move outward, so that the cutting assembly cuts the plastic. During the movement of the plastic, the heating pads 27 on the side plate 26 will heat the plastic to optimize the slicing efficiency; During the cutting process, the rotating motor 20 drives the ring seat 17 to rotate on the base 2. Each cutting assembly moves in a circular motion around the base 2. The functional motor 14 drives the cam 15 to rotate. Thus, the driving plate 10 on the Z-shaped seat 3 changes its position with the extrusion of the cam 15. After the position of the cam 15 changes, under the reverse acting force of the return spring 13, the driving plate 10 resets. With the high-speed rotation of the cam 15, the two driving plates 10 drive the cutting wire 11 to move up and down reciprocally to cut the plastic, so that the plastic is cut into plastics with uniform specifications. During this process, the suction box 6 filters the external gas and conveys it to the air pump 7 for pressurization, and then discharges it through the exhaust port 9. The discharged gas blows the cut plastic to remove the debris adhering to the surface of the plastic, and at the same time assists the plastic to flatten and fall off to improve the slicing effect.
