[0002] Plastics are macromolecular compounds polymerized from monomers through addition polymerization or polycondensation reactions. In the process of plastic particle processing, a cold pelletizer is required to cut plastic strips into pellets.

[0003] A Chinese patent discloses a cold pelletizer for plastic particle processing, with the publication number CN214000132U, which includes a mounting frame. The front surface of the mounting frame is fixedly connected with a tool box by bolts, and a second motor is installed on the front surface of the tool box. One side of the second motor is provided with a main shaft, and one end of the main shaft extends into the tool box. A tool disc is installed on the main shaft, and blades are fixedly connected to the outer wall of the tool disc by bolts; a first roller frame is installed on the front surface of the mounting frame near the tool box, and a second roller frame is installed below the first roller frame. Rollers are rotatably connected to the first roller frame and the second roller frame through rotating shafts. By providing a guide plate, a first roller frame and a second roller frame on the mounting frame, the feeding speed is increased. By installing a knife sharpening frame inside the tool box, the blades are polished during the process of cutting plastic rods, improving the service life of the blades.
