It only needs to rotate one circle to cut out a plurality of plastic pellets, and the pelletizing rate is relatively high. Driven by the first servo motor 201, the rotating pelletizing blade 209 maintains a uniform rotation speed, so as to ensure the uniformity of pelletizing and provide a relatively uniform and stable plastic pellet feeding for subsequent packaging. The partition baffle 207 cooperates with the partition groove 210 to separate the plastic strips for cutting, so as to prevent the plastic strips from overlapping and affecting the cutting process.
