A gear ring 2 405 is sleeved and fixed at the upper edge of the processing cylinder 402, and the two groups of gear rings 2 405 are respectively engaged with the two sides of the gear ring 1 206.

[0061] After the annular cavity 404 is opened by the fixing plate 406, the integrity of the processing cylinder 402 is ensured, and the annular cavity 404 can ensure that the raw materials enter the processing cylinder 402, and through the rotation of the gear ring 1 206, the gear ring 2 405 can be rotated, thereby rotating the processing cylinder 402.

[0076] S2: The raw material in the electric heating cylinder 201 is transported to the processing cylinder 402 through the electromagnetic valve tube 508, and the processing cylinder 402 needs to use an external cooling device to perform fixed-point cooling on the surface, such as fan cooling, so that the reciprocating internal thread cylinder 505 pushes the reciprocating screw 502 to move under the power of the motor 204, so that the extrusion cylinder 501 moves downward along the processing cylinder 402, so that the raw material passes through the holes in the sieve cylinder 701, so that the raw material is cylindrical;

[0077] S3: Since the mixing drum 203 drives the gear ring 2 405 to rotate through the gear ring 1 206, the gear ring 2 405 drives the processing drum 402 to rotate, so that the cylindrical strip of raw material slides along the cutting blade 705, thereby cutting the raw material and processing the raw material into plastic particles;

[0078] S4: The arc-shaped tooth plate 702 is driven to rotate by the sieve cylinder 701, so that the arc-shaped tooth plate 702 squeezes the protruding block plate 708, so that the guide hopper 703 swings, so that the processed plastic particles can be smoothly transported.

[0079] like Figure 1-12As shown, different raw materials are added into the two groups of feeding barrels 301, and the motor 204 is started at this time, so that the motor 204 drives the stirring barrel 203, the bevel gear four 205, the gear ring 1 206 and the stirring rod 207 to rotate, so that the threaded shaft 304 rotates, and the raw materials are added into the electric heating barrel 201, and the individual rotation of the two groups of threaded shafts 304 is controlled to achieve individual and accurate filling of the raw materials. At the same time, the stirring rod 207 stirs the various raw materials in the electric heating barrel 201 to achieve rapid mixing. The reciprocating screw 502 is driven to move by the reciprocating internal threaded barrel 505, so that one group of extrusion barrels 501 drives the touch block 504 to contact the touch switch 507, so that the solenoid valve tube 508 is opened, and the mixed raw materials are added into the processing barrel 402. At the same time, the other group is in a lifting state. When the touch block 504 that rises to this point contacts the touch switch 507, the solenoid valve tube 508 is opened, and the mixed raw materials are added into the processing barrel 402. 7, the electric push rod 603 drives the position of the rotating shaft 602 to move, so that the extrusion cylinder 501 above the processing cylinder 402 containing the raw material is lowered, so that the extrusion cylinder 501 extrude the raw material, and the raw material is extruded into a cylindrical strip through the sieve cylinder 701, and the rotation of the processing cylinder 402 can make the sieve cylinder 701 move along the cutting blade 705 to cut the extruded raw material into particles, and the shaking of the guide hopper 703 can ensure the transportation and packaging of the particle raw material to avoid material blockage. In this way, accurate filling of various materials can be achieved, thereby improving the filling efficiency of the raw materials, and particles of different sizes can be processed during the processing, and this cutting method ensures the quality of the finished particles, and can also use its own power to effectively avoid particle blockage, and this processing method is fully automatic, which effectively improves the quality and efficiency of particle processing.
