A driving motor 7 is coaxially installed on the second pulley 5. The driving motor 7 is arranged on a support frame 8, and a feed hopper 9 is installed on the top of the cylinder 1 near one end of the first pulley 4. The plastic pellet production raw materials are added from the feed hopper 9 into the cylinder 1, the raw materials are melted under the heating of the heating plate, and as the spiral conveying shaft 2 rotates, the raw materials are pushed to the molding device for molding.

[0032] like Figure 3 and Figure 4 As shown, the molding device includes a first cylindrical seat 10, which is installed at the outlet of the extrusion device through a flange, that is, the first cylindrical seat 10 is installed on one end of the cylinder 1 close to the fixing frame 3, and a wide-mouthed conical cavity 11 is coaxially opened in one end of the first cylindrical seat 10 close to the extrusion device, and a strip-shaped first limiting groove 13 is opened at the other end of the first cylindrical seat 10, and a strip groove 12 is opened in the first limiting groove 13, and the strip groove 12 is connected with the conical cavity 11. After the raw material enters the conical cavity 11, the radius of the conical cavity 11 is gradually reduced to squeeze the raw material, thereby increasing the pressure of the raw material when entering the strip groove 12, which is helpful for the subsequent molding of the plastic tube;

[0033] A strip plate 14 is correspondingly arranged in the first limiting groove 13, and a plurality of first through holes 15 arranged at intervals are opened in the strip plate 14. A core rod 16 is coaxially arranged in the first through hole 15, and the core rod 16 is connected to the inner wall of the first through hole 15 through a connecting member 17, wherein the connecting member 17 is a plurality of arc-shaped plates arranged at intervals and inclined in the same direction, one end of the arc-shaped plate is fixed on the core rod 16, and the other end of the arc-shaped plate is fixed on the inner wall of the first through hole 15, so that the raw materials flowing out of the first through hole 15 can flow in a spiral shape, so that the raw materials can be better concentrated;

[0034] The utility model also includes a second cylindrical seat 18 coaxially arranged with the first cylindrical seat 10. In the second cylindrical seat 18, a second limiting groove 19 corresponding to the first limiting groove 13 is provided at one end of the second cylindrical seat 18 close to the first cylindrical seat 10. A second through hole 29 corresponding to the first through hole 15 is provided in the second limiting groove 19. A cooling cavity 20 is provided at the other end of the second cylindrical seat 18.

After the second cylindrical seat 18 is installed on the first cylindrical seat 10, the core rod 16 will be coaxially placed in the forming tube 21, so that a mold cavity for molding the plastic tube is formed between the core rod 16 and the forming tube 21. At this time, the raw material flowing out of the first through hole 15 will flow to the discharge port 27 in the forming tube 21, thereby forming a plastic tube.

The water cooling box 28 is installed on the support frame 8, and a water pump connected to the connecting pipe is installed on the water cooling box 28. The water pump is installed with a conduit placed in the water cooling box 28 to deliver the cooling water in the water cooling box 28 to the cooling chamber 20. In combination with the heat conduction of the forming tube 21, the plastic tube formed in the forming tube 21 is cooled, so that the plastic tube will not be excessively bent and damaged during discharge, or wrinkles will not occur on the inner and outer surfaces.

[0036] Specifically, when in use, the raw materials for producing plastic pellets are placed in the feed hopper 9. Under the heating of the heating plate and the conveying of the spiral conveyor shaft 2, the raw materials flow into the conical cavity 11, and then enter the forming tube 21, forming a tubular structure in the mold cavity formed by the core rod 16 and the forming tube 21. While forming, the water pump on the water cooling box 28 passes cooling water into the cooling cavity 20, thereby preliminarily cooling the extruded plastic tube, allowing the plastic tube to cool down and harden, and then squeezed from the discharge port 27 into the water tank for complete cooling, and finally the pelletizing is completed by the cutting device.

[0037] Furthermore, sealing rings are installed on the inner wall of the first limiting groove 13 and the inner wall of the second limiting groove 19 to improve the fastening effect of the strip plate 14 in the limiting groove and ensure the sealing at the edge of the strip plate 14.

[0038] Furthermore, a sealing gasket is installed along the outer wall of the connecting seat 26 to improve the airtightness of the cover plate 25 on the second cylindrical seat 18 .
