For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field.

[0029] PE is the abbreviation of polyethylene. Generally, the application range of PE pipe water supply pipeline is below 40℃, and it cannot be used for hot water delivery pipeline. PE pipe is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and it is translucent to a certain extent in the thin section. At present, in the production process of antibacterial PE pipe, the pipe needs to be cooled and formed by a cooling device after being extruded by an extruder. The existing cooling device generally cools the pipe by spraying.

[0030] In the related art, a cooling box is generally used to pass the extruded PE water supply pipe through the cooling box. A spray pipe is arranged inside the cooling box to spray coolant on the surface of the PE water supply pipe to cool the PE water supply pipe. However, the existing spray device is generally fixed in design and its position cannot be adjusted according to the diameter of the PE water supply pipe.

[0031] In order to solve the problems in the related art to a certain extent, an embodiment of the present application provides a PE water supply pipe spray device. When the PE water supply pipe 13 needs to be cooled, the extruded end needs to be passed through the round tube on the cooling box, and then the water outlet pipe of the water pump is connected to the spray pipe 24. The turning knob 25 drives the bidirectional screw 23 to rotate. This is because the sliding rod 22 restricts the moving block 21, and the bidirectional screw 23 can push the two moving blocks 21 closer, so that the top spray pipe 24 is close to the outside of the PE water supply pipe 13. When the PE water supply pipe 13 passes through the cooling box 11, the spray pipe 24 can cool it.

[0032] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Combination Figure 1-Figure 5 The embodiment of the present application provides a PE water supply pipe spraying device, comprising: a cooling box 11, a cover 12 is arranged on the top of the cooling box 11; one end of a PE water supply pipe 13 passes through the interior of the cooling box 11; a spray assembly 2 is arranged inside the cooling box 11, and the spray assembly 2 comprises: a moving block 21, which is symmetrically arranged inside the cooling box 11; a sliding rod 22 symmetrically passes through the moving block 21 at one end, and is connected to the inner wall of the cooling box 11 at both ends; one end of a bidirectional screw 23 passes through the cooling box 11 and the moving block 21, and is rotatably connected to the cooling box 11 and threadedly connected to the moving block 21; a spray pipe 24 is arranged on the top of the moving block 21.

[0034] Specifically, the bottom of the spray pipe 24 is connected to the water outlet pipe of the water pump, which belongs to the existing well-known technology and is not shown in the figure.

[0035] During use, when the PE water supply pipe needs to be cooled, the extruded end is passed through the round tube on the cooling box, and then the water outlet pipe of the water pump is connected to the spray pipe 24, and the bidirectional screw 23 is rotated. This is because the sliding rod 22 restricts the moving block 21, and the bidirectional screw 23 can push the two moving blocks 21 closer, so that the top spray pipe 24 is close to the outside of the PE water supply pipe 13. When the PE water supply pipe 13 passes through the cooling box 11, the spray pipe 24 can cool it.

[0036] In some embodiments, the spray pipe 24 is arc-shaped.

[0037] When in use, the arc-shaped design allows the sprayed coolant to better wrap around the outer wall of the PE water supply pipe 13 .

[0038] In some embodiments, the two spray pipes 24 are staggered and disposed on the top of the moving block 21 .

[0039] When in use, the staggered arrangement can ensure that the coolants sprayed from the two spray pipes 24 do not affect each other.

[0040] In some embodiments, the spray assembly 2 further includes: a twisting knob 25 disposed at one end of the bidirectional screw 23 .

[0041] When in use, the setting of the knob 25 can make it easier to grip the bidirectional screw 23 and make it easier to rotate.

[0042] In some embodiments, the spray assembly 2 further includes: a rubber pad 26 disposed on one side of the moving block 21 .

[0043] When in use, the rubber pad 26 can mitigate the collision caused by the two moving blocks 21 moving closer to each other.

[0044] In some embodiments, the spray assembly 2 further includes: a plurality of balls 27 are provided, all of which are arranged at the bottom of the moving block 21 .

[0045] When in use, the provision of the balls 27 can reduce the friction between the moving block 21 and the inner wall of the cooling box 11, making the movement smoother.

[0046] In some embodiments, the spray assembly 2 further includes: a plurality of drainage holes 28 are provided, all of which are opened on the outer wall of the cooling box 11 .

[0047] When in use, the provision of the drainage hole 28 can prevent water from accumulating inside the cooling box 11 .

[0048] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

[0049] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
