[0029] The working principle of the above embodiment is:

[0030] (1) When the waste plastic bottles are compressed before slicing, the waste plastic bottles are put into the machine through the feed port of the chassis 1 through the feed hopper 29. The waste plastic bottles slide into the compression frame 22 along the drainage pipe 210 at the bottom of the feed hopper 29.

The drive motor 34 is started, and the rotating shaft 32 drives the slicing knife 33 to rotate. The slicing knife 33 slices the portion of the waste plastic bottles extending out of the discharge pipe 28. As the drive motor 34 continues to operate, the slicing knife 33 achieves continuous slicing. The cut plastic sheets are discharged from the output end of the slicing mechanism 3 into the collection frame 36 for collection. After slicing is completed, the drive motor 34 is turned off, the rotation of the slicing knife 33 is stopped, and the equipment is cleaned and maintained.
