[0028] Working principle: During the processing stage, the motor 31 in the drive assembly 3 is started. The drive end of the motor 31 drives the reducer 32 to run. The reducer 32 drives the rotating shaft 33 to rotate. When the rotating shaft 33 rotates, the two eccentric wheels 34 fixed on its outside rotate accordingly. The eccentric wheels 34 drive the connecting block 36 to move through the rotating linkage block 35. The connecting block 36 transmits power through the connecting shaft and the fixing rings 37 at both ends. Due to the movement of the connecting shaft, the movable connecting ring 313 will slide back and forth vertically on the guide rod 312. The cutter head assembly 4 fixed inside the movable connecting ring 313 will also reciprocate. Under the fixing action of the cutter head mounting shell 41 and the fixing bolt 42, the slicing blade 43 in the cutter head assembly 4 performs a cross-sectional slicing operation on the plastic part positioned below. The fixing plate 38 and counterweight plate 39 on the right side of the rotating shaft 33, as well as the fixing plate 38 on both sides of the shaft 51 and the counterweight plate 39 at both ends, all play the role of balancing the rotating parts and stabilizing the operation of the device. In the frame assembly 2, two mounting plates 21 are fixed on the top two sides of the base plate 1, providing a support foundation for the entire device. The connecting fixing plate 22 and the stabilizing plate 23 further enhance the connection stability between the mounting plates 21. The support plate 24 provides a platform for the motor 31 to be installed and fixed. After processing, the plastic slices are detached from the auxiliary positioning assembly 5 under their own weight or the push of subsequent plastic parts, completing the discharge process. If it is necessary to collect the slices, a collection device can be placed at the discharge position. No additional packaging-related parts are required to directly collect the slices.

[0029] Under the elastic action of the spring 55, the limiting slide plate 54 in the auxiliary positioning component 5 drives the baffle 57 to move inward through the connecting rod 56. The two baffles 57 are used to initially clamp and position the plastic part, ensuring that the position of the plastic part is stable in the horizontal direction. At the same time, the shaft 51 can rotate inside the two mounting plates 21, and the auxiliary feeding roller 52 fixed in the middle of its outer side contacts the plastic part, providing auxiliary support for subsequent feeding.
