[0039] Preferably, the model of the PLC controller 63 is CPM1A-10CDR-A-V1.

[0040] A specific embodiment of the present invention is:

[0041] like Figure 1 As shown, plastic particles are melted in the furnace 12 and enter the conveying cylinder 1 through the feed pipe 11. When the motor 33 is working, it drives the conveying shaft 3 and the conveying blades 31 to rotate. The conveying blades 31 convey the molten plastic from left to right and pass through the transition portion 14 into the space between the central tube 2 and the extrusion portion 15. A plastic hose is formed between the central tube 2 and the extrusion portion 15.

[0042] During this process, the pumping mechanism delivers the coolant to the liquid inlet pipe 25 and the first chamber 23 , the coolant flows in the flow pipe 210 , and flows back to the storage tank 13 through the second chamber 24 and the return pipe 26 .

[0043] like Figure 4 As shown, when the coolant is located in the heat insulating portion 201, the heat insulating portion 201 itself and the heat insulating cotton 28 prevent the transfer of heat, thereby avoiding the cooling of the molten plastic at this time, so that the molten plastic can be smoothly extruded and molded. When the coolant is located in the heat conducting portion 202, the heat of the plastic hose is absorbed by the heat conducting portion 202 itself and the oil 29, thereby cooling the molded plastic hose.

[0044] like Figure 2 As shown, when the conveying shaft 3 rotates, the driving wheel 46 fixed thereto rotates, and under the action of the belt 47, the driven wheel 45 and the driving shaft 41 rotate. Since the piston 42 is engaged with the reciprocating thread groove 44 on the driving shaft 41, the piston 42 reciprocates left and right. The setting of the vent hole 48 allows the piston 42 to move smoothly. When the piston 42 moves, the coolant is extracted through the liquid extraction pipe 49 and the coolant is transported to the liquid inlet pipe 25 through the liquid outlet pipe 410 and the connecting pipe 411.

[0045] like Figure 2 As shown, when the drive shaft 41 rotates, the fan blade assembly 53 fixed thereon rotates, so that air flows in the heat dissipation pipe 51, thereby cooling the coolant.

[0046] like Figure 3 and 8 As shown, under normal circumstances, the coolant can be cooled by the arrangement of the fan blade group 53 and the heat dissipation pipe 51. When the cooling is not timely, the temperature sensor 62 detects the temperature rise of the coolant and transmits the temperature rise signal to the PLC controller 63. The PLC controller 63 controls the operation of the semiconductor refrigeration plate 61, thereby further cooling the coolant.
