[0032] (1)First, the plastic raw materials are fed into the screw extruder 1 through the raw material hopper 2, and the raw materials are heated and melted by the screw extruder 1 and then extruded. The extruded plastic material enters the cooling box 3. The first motor 401 is turned on, and the output shaft of the first motor 401 drives the first rotating rod 402 to rotate. The first rotating rod 402 drives the first transmission roller 403 to rotate, and the first transmission roller 403 drives the transmission net 404 to transmit. The transmission net 404 transmits the plastic material, which is then rapidly cooled by the cooling water in the cooling box 3. Then the transmission net 404 transports the plastic material out of the cooling water surface, and the transmission net 404 filters out the cooling water. At this time, the plastic material is cooled again by the fan 415, improving the efficiency of plastic material cooling and solidification.

Then the water outlet pipe 411 feeds the cooling water into the cooling box 3, making the cooling water in the cooling box 3 flow, improving the cooling effect. The cooling water after absorbing heat returns to the water tank 407, and the refrigeration fin 412 discharges the heat absorbed by the cooling water, making the cooling water circulate.

[0033] (2) After the cooling work is completed, the plastic material enters the mounting plate 501. At this time, the second motor 503 is turned on, and the first shaft 504 is driven to rotate by the second motor 503. The first pulley 505 is driven to rotate by the first shaft 504, and the transmission belt 506 is driven to rotate by the first pulley 505. The second pulley 507 is driven to rotate by the transmission belt 506, and the second shaft 508 is driven to rotate by the second pulley 507, so that the second shaft 508 rotates in the same direction as the first shaft 504. The second shaft 508 drives the feeding roller 509 to rotate, and the feeding roller 509 transports the solidified plastic material to the right side. At this time, the first shaft 504 drives the pelletizing roller 510 to rotate, and the pelletizing knife 511 is driven to rotate by the pelletizing roller 510. The plastic material moves to the pelletizing knife 511, and the pelletizing knife 511 cuts the plastic material into particles, which are convenient for storage and transportation.
