[0032] Refer to Figure 1 、 Figure 2, A pipe cooling device according to an embodiment of the present utility model includes a housing 100 and a cooling assembly 200. The housing 100 is provided with a cooling chamber 110. The cooling chamber 110 has a first opening 120 and a second opening 130 oppositely arranged along a first direction. The cooling assembly 200 is arranged in the cooling chamber 110. The cooling assembly 200 includes a connecting member 210, a first spray head group 220, and a second spray head group 230. The connecting member 210 is provided with an avoidance hole 211 and a water inlet channel 212. The avoidance hole 211 is used for a pipe to pass through. The avoidance hole 211 communicates with the first opening 120. The water inlet channel 212 extends along the circumferential direction of the first opening 120. The first spray head group 220 and the second spray head group 230 are arranged at intervals along the first direction, and both the first spray head group 220 and the second spray head group 230 are arranged on the side wall of the avoidance hole 211. Among them, the first spray head group 220 includes a plurality of first spray heads 220 arranged at intervals along the circumferential direction of the avoidance hole 211, and the second spray head group 230 includes a plurality of second spray heads 230 arranged at intervals along the circumferential direction of the avoidance hole 211. The plurality of first spray heads 220 and the plurality of second spray heads 230 are both communicated with the water inlet channel 212. In the circumferential direction of the avoidance hole 211, the second spray head 230 is located between two adjacent first spray heads 220. Thus, when the pipe enters the cooling chamber 110 through the first opening 120, the pipe passes through the avoidance hole 211, and the plurality of first spray heads 220 and the plurality of second spray heads 230 both spray cooling water onto the outer surface of the pipe. When the pipe moves, all positions on the outer surface of the pipe can be cooled, which can not only improve the cooling effect of the pipe but also ensure uniform cooling of the pipe to improve the production quality of the pipe.

[0033] Specifically, when cooling the pipe, the pipe passes through the first opening 120 and enters the cooling chamber 110. At this time, the pipe passes through the avoidance hole 211. Since the plurality of first spray heads 220 and the plurality of second spray heads 230 both face the axis of the avoidance hole 211, the plurality of first spray heads 220 and the plurality of second spray heads 230 both spray cooling water onto the outer surface of the pipe. When the pipe moves, all positions on the outer surface of the pipe can be cooled, which can not only improve the cooling effect of the pipe but also ensure uniform cooling of the pipe to improve the production quality of the pipe.

[0034] It should be noted that the water inlet channel 212 can be connected to a water pump to provide water source for the first spray head 220 and the second spray head 230, so that the first spray head 220 and the second spray head 230 can continuously spray water to cool the pipe, which will not be elaborated here.

[0035] It should be noted that by setting the first spray heads 220 and the second spray heads 230, the water spray volume of the water inlet channel 212 can be increased within the limited space of the avoidance holes 211, thereby improving the cooling effect of the pipe cooling device. Moreover, by arranging the second spray heads 230 between adjacent first spray heads 220, the water sprayed out of the avoidance holes 211 is more uniform, which can ensure uniform cooling of the pipe and will not be elaborated here.

[0036] It should be pointed out that the first spray heads 220 and the second spray heads 230 are in one-to-one correspondence, and one second spray head 230 is arranged between two adjacent first spray heads 220, which can improve the cooling effect of the pipe and will not be elaborated here.

[0037] It should be pointed out that both the first spray heads 220 and the second spray heads 230 can convert the water flow into fine water droplets, so that the water in the water inlet channel 212 can fully contact the outer surface of the pipe to improve the cooling speed of the pipe, thereby improving the cooling effect of the pipe, which will not be elaborated here.

[0038] Refer to Figure 3 、 Figure 4 In some embodiments of the present invention, a plurality of first spray heads 220 are evenly spaced along the circumferential direction of the avoidance holes 211, which can ensure uniform cooling of the pipe and improve the production quality of the pipe.

[0040] Refer to Figure 3 、 Figure 4 In some embodiments of the present invention, a plurality of second spray heads 230 are evenly spaced along the circumferential direction of the avoidance holes 211, which can ensure uniform cooling of the pipe and improve the production quality of the pipe.

[0041] Specifically, along the circumferential direction of the avoidance holes 211, a plurality of second spray heads 230 are equally spaced on the side walls of the avoidance holes 211, which can ensure uniform cooling of the pipe and improve the production quality of the pipe.

[0042] Refer to Figure 5, in some embodiments of the present utility model, the connecting member 210 includes a first plate body 213, a second plate body 214, a third plate body 215, and a fourth plate body 216.

The third plate body 215 and the fourth plate body 216 are arranged opposite to each other along the first direction. The avoidance hole 211 is provided on the first plate body 213. The first plate body 213, the second plate body 214, the third plate body 215, and the fourth plate body 216 enclose to form a water inlet channel 212, which is convenient for manufacturing the connecting member 210.

The plurality of second water outlet holes 242 are arranged at intervals along the first direction, and the first water outlet holes 241 and the second water outlet holes 242 are arranged at intervals along the circumferential direction of the pipe body 240, which can increase the water output of the pipe body 240 to improve the cooling effect of the pipe material cooling device.
