By spraying evenly on the surface of the pipe through a circle of spray heads 12, the cooling effect is good, the water body flows, and the heat dissipation effect is better;

[0028] At the left end of the sump 3, a mounting plate 15 is fixedly installed. A front pressing plate 16 is slidably installed at the inner end of the mounting plate 15. A rear pressing plate 17 is fixedly installed at the rear end of the mounting plate 15. An electric telescopic rod 18 is fixedly installed at the rear end of the rear pressing plate 17.

[0029] Specific working principle:

[0030] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, when using the extrusion device for PVC pipe production, the raw materials are added through the feeding hopper 7. After being heated and conveyed by the conveying box 6, the PVC pipe is extruded through the extrusion box 4 and the extrusion head 5. The extruded PVC pipe enters the inside of the water-cooling box 2 through the opening 13, passes through the annular pipe 11. The water pump 9 pumps the water inside the water-cooling box 2 through the connecting pipe 10 into the inside of the annular pipe 11, and then sprays it evenly on the outside of the PVC pipe through the spray head 12 for cooling treatment. Then the water falls into the inside of the water-cooling box 2 and continues to be used. Water can be added or changed through the water inlet 14. The PVC pipe after water-cooling passes through the water-absorbing sponge cylinder 19, and the water-absorbing sponge cylinder 19 absorbs the water droplets on the surface of the PVC pipe. When the water-absorbing sponge cylinder 19 is saturated with adsorption, the electric telescopic rod 18 drives the front pressing plate 16 to move backward to squeeze the water-absorbing sponge cylinder 19. The front pressing plate 16 slides at the inner end of the mounting plate 15, and the rear pressing plate 17 remains stationary. The squeezed water falls into the inside of the sump 3 for collection and is discharged and cleaned regularly. The above completes a series of operations of the extrusion device for PVC pipe production.
