[0033] Furthermore, the output shaft of the driving motor 9 passes through the motor bracket 8, and the double-groove pulley 10 is sequentially connected to the two single-groove pulleys 11 through two transmission belts 12;

[0034] Then, by setting the driving assembly, the feeding roller 4 and the pelletizing roller 5 can be controlled by the same driving motor 9, which makes the control more convenient, improves the utilization rate of the driving motor 9, and is conducive to reducing costs;

[0035] In the specific implementation of this embodiment: the double-groove pulley 10 is driven to rotate by the driving motor 9, and then under the transmission effect of the two transmission belts 12, the two single-groove pulleys 11 will drive the feeding roller 4 and the pelletizing roller 5 to rotate in turn, so that the plastic products fed from the feeding port can be automatically conveyed by the rotation of the feeding roller 4, and the plastic products fed in can be automatically cut by the rotation of the pelletizing roller 5.
