[0025] The specific operation is as follows: start the drive motor 6, drive the metal rod 7 and the stirring rod 8 to rotate through the drive motor 6, and use the rotating stirring rod 8 to stir the material in the material tank 2 to ensure that the material is uniform. At the same time, the gear 1001 rotates with the metal rod 7, and drives the gear 2 1003 to rotate through the meshing transmission of the transmission chain 1002, thereby driving the reciprocating screw 901 to rotate, and cooperate with the guide rail 11 and the guide groove 905 to limit the movement trajectory of the scraper ring 904, so that the movable block 903 and the scraper ring 904 can move around the reciprocating screw 901. 1 is driven by the rotation of the material tank 1 to reciprocate and rise and fall.

At the same time, the gear 1 1001 rotates with the metal rod 7, and drives the gear 2 1003 to rotate through the meshing transmission of the transmission chain 1002, thereby driving the reciprocating screw 901 to rotate, and the guide rail 11 and the guide groove 905 limit the movement trajectory of the scraper ring 904, so that the movable block 903 and the scraper ring 904 can be reciprocated and lifted under the rotation drive of the reciprocating screw 901, and the scraper ring 904 that is reciprocated can scrape and clean the inner wall of the material tank 2, and then the masterbatch enters the extrusion structure 1 from the material tank 2, and is pushed to the extrusion head 12 through the extrusion structure 1. Various products are extruded according to the shape of the extruder head 12 and enter the extension sleeve 13. At the same time, the water pump 1604 draws the coolant from the water tank 17 and sends it into the water tank 1601 along the connecting pipe 1603, and then sprays it to the outer surface of the extension sleeve 13 through the water distributor 1602. The coolant carries away the heat of the extension sleeve 13 to cool the product in the extension sleeve 13. Then the coolant flows along the outer surface of the extension sleeve 13 and falls into the drainage groove 15 below, and then enters the water tank 17 along the drainage groove 15. After the coolant enters the water tank 17, it will flow along the trajectory specified by the refrigeration plate 18. In this process, the refrigeration plate 18 can cool the coolant to restore its original temperature and return to the bottom position in the water tank 17 to realize the circulation of the coolant.
