The upper end of the delivery pipe 301 is connected to the water pump 5 by bolts. The circulation pipe 7 is connected between the right ends of the two water pipes 4. The water in the delivery pipe 301 is transported to the water inlet 3, the front water pipe 4, the circulation pipe 7 and the rear water pipe 4 in turn through the operation of the water pump 5.

[0026] See also Figure 1 and Figure 4-Figure 6 As shown, it also includes a motor 9, a front rotating wheel 11, a rear rotating wheel 1101, a pulley assembly 10, a connecting rod 12 and a controller 18. The motor 9 is connected to the left side of the outer surface of the water tank 201 by bolts, and the front rotating wheel 11 and the rear rotating wheel 1101 are rotatably connected on the left and right sides of the outer shell 2, and the inner walls of the front rotating wheel 11 and the rear rotating wheel 1101 are provided with oblique protrusions made of soft rubber material.

[0028] First, the staff puts the plastic pipe to be cooled into the shell 2, so that the plastic pipe is placed between the front and rear groups of nozzles 6. At this time, the left and right ends of the plastic pipe are in contact with the front rotating wheel 11 and the rear rotating wheel 1101 respectively. Then, the external pipe is connected to the water inlet 3, so that water flows from the water inlet 3 into the front water pipe 4, the circulation pipe 7 and the rear water pipe 4 in turn, and then sprays out from the nozzle 6 to the surface of the plastic pipe, thereby cooling the plastic pipe.
