[0041] Please refer to Figures 1 to 7 The present application discloses a cooling device for plastic pipe production, which can be used to improve the uneven cooling effect of the single cross section of the existing plastic pipe during the cooling process. The cooling device for plastic pipe production includes at least a box body 100 and a first cooling assembly connected to the box body 100. It can be understood that the first cooling assembly can realize the cooling treatment of the pipe.

[0042] In one embodiment, the first cooling assembly includes a plurality of groups, and the plurality of groups of first cooling assemblies are connected to the mounting disc 120. At the same time, the plurality of first cooling assemblies are actually uniformly distributed around the circular hole 101. By uniform distribution, it can ensure that the cooling of the pipe is in a uniform state.

[0043] In one embodiment, the first cooling assembly includes a plurality of groups, and the plurality of groups of first cooling assemblies are connected to the mounting disc 120. At the same time, the plurality of first cooling assemblies are actually uniformly distributed around the circular hole 101. By uniform distribution, it can ensure that the cooling of the pipe is in a uniform state.

[0044] The first cooling assembly comprises a first cooling rod 125 and a plurality of first cooling nozzles 123. The first cooling rod 125 is movably connected to the mounting disc 120, and the moving direction of the first cooling rod 125 is along the radial direction of the circular hole 101. By movably connecting the first cooling rod 125 to the mounting disc 120, the device can be suitable for pipes of different diameters, thereby improving the use effect of the device in actual use.

[0045] For example, in an embodiment, a plurality of sliding blocks 1211 can be slidably connected to the mounting disc 120, and a screw rod 1212 is rotatably connected to the sliding block 1211. Therefore, by rotating the screw rod 1212, the sliding block 1211 can slide relative to the mounting disc 120. For example, a sliding groove 122 can be formed on the mounting disc 120, and the sliding block 1211 is slidably connected in the sliding groove 122.

[0046] The end of the screw rod 1212 can be fixedly connected with a rotating block 121, and the rotating block 121 is driven to rotate to realize the rotation of the screw rod 1212. It can be understood that the number of screw rods 1212 is the same as that of the first cooling rod 125, and they are uniformly distributed on the mounting disc 120. For the first cooling rod 125, it is fixedly connected to the sliding block 1211. By sliding the sliding block 1211, the position of the first cooling rod 125 can be adjusted. In order to improve the actual use effect of the device, the screw rod 1212 has a trapezoidal tooth structure. By the self-locking function of the trapezoidal tooth, the use effect of the device can be effectively improved, thereby avoiding the sliding of the first cooling rod 125 during cooling.

[0047] A plurality of first cooling nozzles 123 are fixedly connected to the first cooling rod 125, and a nozzle 124 is provided on the first cooling nozzle 123. At the same time, a cooling liquid supply assembly is also allowed to be connected to the first cooling rod 125, so that the cooling liquid can be sprayed out through the nozzle 124. The cooling liquid supply assembly can be determined according to actual needs, which is not limited.

[0048] It should be noted that the pipe for cooling is concentrically arranged with the circular hole 101, and the cooling liquid sprayed from the first cooling nozzle 123 is along the tangent direction of the pipe. Therefore, the nozzles 124 of the plurality of first cooling nozzles 123 can greatly improve the cooling effect of the pipe, and the tangential direction of the cooling liquid can be used to accelerate the heat exchange of the pipe, and the heat dissipation of the pipe in a single cross section is in a uniform state.

[0049] In an embodiment, the box 100 is also allowed to be connected with a second cooling assembly, which is located on the moving path of the pipe and behind the first cooling assembly. After the pipe is cooled by the first cooling assembly, the surface of the pipe is preliminarily solidified, so that the pipe is not easy to deform. Therefore, the pipe is further cooled by the second cooling assembly, so that the cooling effect of the pipe is further improved.

[0050] The second cooling assembly comprises at least one connecting bracket 130 and a plurality of second cooling nozzles 131 located on the connecting bracket 130. The connecting bracket 130 is fixedly connected to the box 100, and the plurality of second cooling nozzles 131 are uniformly connected to the connecting bracket 130. The second cooling nozzles 131 are in communication with the cooling liquid supply assembly, so that the cooling liquid supply process of the second cooling nozzles 131 is realized through the cooling liquid supply assembly. In order to improve the cooling effect of the second cooling nozzles 131 on the pipe, the second cooling nozzles 131 can be atomizing nozzles.

[0051] In an embodiment, a plurality of rolling shafts 111 are rotatably connected in the box 100, and the pipe to be cooled can move on the rolling shafts. Since the pipe and the circular hole 101 are coaxially arranged and are adapted to pipes with different diameters, the rolling shafts 111 can also slide along the inner wall of the box 100, so that the positions of the rolling shafts 111 can be adjusted according to pipes with different diameters.

[0052] Further, the bottom of the box 100 is also connected with a plurality of foot supports 110, which can effectively improve the stability of the device during actual use.

[0053] In summary, the cooling device for plastic pipe production disclosed by the utility model is characterized in that a plurality of first cooling assemblies are uniformly distributed around the circular hole 101. The uniform distribution ensures that the cooling of the pipe is in a uniform state. Meanwhile, the pipe to be cooled is concentrically arranged with the circular hole 101, and the cooling liquid sprayed from the first cooling nozzles 123 is along the tangent direction of the pipe. The tangential cooling liquid can accelerate the heat exchange of the pipe and make the heat dissipation of the pipe in a single cross section be in a uniform state.

[0054] Therefore, the utility model can be used for improving the problem that the cooling effect of the single cross section of the existing plastic pipe is uneven during the cooling process. Therefore, the utility model effectively overcomes some practical problems in the prior art, so that it has high utilization value and use significance.
