[0033] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0034] like Figures 1 to 6As shown, a cooling and forming device for producing polymer PE pipes is mainly used to cool the produced polymer PE pipes; of course, it can also be used to cool other types of pipes. This cooling and forming device for producing polymer PE pipes includes a base frame 1, a cooling box 2, a pipe track conveyor line 3, a pipe hook frame 4, a first arc spray assembly 5, a second arc spray assembly 6, a first water-cooling supply device 8, and a second water-cooling supply device 9. The pipe track conveyor line 3 is horizontally positioned at the top of the cooling box 2, relative to the front of the cooling box 2. This changes the traditional method of linearly conveying pipes within the cooling box 2, reducing obstruction of the pipes during spray cooling, facilitating smooth entry and exit from the cooling area, and resulting in a more uniform cooling effect. The cooling box 2 has a first water-cooling chamber 21 and a second water-cooling chamber 22 connected sequentially, further ensuring the cooling effect of the pipes through segmented cooling. The pipe hook frame 4 is connected to the pipe track conveyor line 3 and is driven by the pipe track conveyor line 3 to move in and out of the first water-cooled cooling chamber 21 and the second water-cooled cooling chamber 22. Two first arc-shaped spray components 5 are positioned opposite each other on both sides of the pipe hook frame 4 and within the first water-cooled cooling chamber 21; two first arc-shaped spray components 5 are positioned opposite each other on both sides of the pipe hook frame 4 and within the second water-cooled cooling chamber 22. The encircling and arc-shaped designs of the first arc-shaped spray components 5 and the second arc-shaped spray components 6 in the first and second water-cooled cooling chambers 21 and 22 respectively not only increase the spray area but also ensure that the spray water can evenly cover the pipe surface, effectively improving cooling efficiency. The first water-cooled water supply device 8 and the second water-cooled water supply device 9 are connected to the first arc-shaped spray components 5 and the second arc-shaped spray components 6 respectively, providing a stable water flow to the spray system and ensuring the continuity and stability of the cooling process.

[0035] This cooling and molding device for producing high-polymer PE pipes utilizes a design where a horizontal pipe track conveyor line 3 is positioned at the top of the cooling chamber 2. Pipe hooks 4 support the pipes as they move sequentially within the first water-cooling chamber 21 and the second water-cooling chamber 22. This minimizes obstruction of the pipe area, increasing the spray area and effectively reducing obstruction caused by the pipe track conveyor line 3 during cooling. This results in more uniform spray cooling. Furthermore, the device incorporates a first arc-shaped spray assembly 5 and a second arc-shaped spray assembly 6 within the first and second water-cooling chambers 21 and 22, respectively. These components utilize a first water-cooling supply device 8 and a second water-cooling supply device 9 to supply cold water at different temperatures. The circumferential and arc-shaped design, compared to direct spraying, ensures that the spray water evenly covers the pipe surface, avoiding quality problems caused by uneven cooling. This increases the spray area, resulting in more uniform spraying and improving the quality and efficiency of pipe cooling.

[0036] The pipe hook frame 4 includes a vertical support rod 41, a horizontal support rod 42, and support hooks 43. The upper end of the vertical support rod 41 is connected to the pipe track conveyor line 3. The horizontal support rod 42 is connected to the lower end of the vertical support rod 41 and extends relative to the front-rear direction of the cooling box 2. At least two support hooks 43 are evenly distributed on the horizontal support rod 42 along its length. The pipe hook frame 4 is formed by combining the vertical support rod 41, the horizontal support rod 42, and the support hooks 43. The pipe hook frame 4 adopts a support rod design, which has a small contact area with the pipe, thus reducing the area obstructed by the pipe. This design results in more uniform spray cooling of the pipe, which is beneficial to improving the quality and efficiency of pipe cooling.

[0037] Preferably, the number of support hooks 43 is 3 or 4. A reasonable design of 3 or 4 support hooks 43 ensures stable support of the pipe during the cooling process. Of course, the number of support hooks 43 can be reasonably designed according to requirements, but at least two are required.

[0038] To minimize the contact area with the pipe and thus reduce the obstructed area, resulting in more uniform spray cooling, the vertical support rod 41, horizontal support rod 42, and support hook 43 are all made of stainless steel bars. Using stainless steel bars to construct the pipe hook frame 4 not only ensures more uniform spray cooling of the pipe but also provides structural stability, good strength and rigidity, and better support for the pipe.

[0039] In this embodiment, the first arc spray assembly 5 includes mounting strips 51, arc strips 52, mounting columns 53, nozzles 54, and water pipes 55; the mounting columns 53 are connected to the side wall of the cooling box 2; the mounting strips 51 extend along the length of the cooling box 2 and are connected to the mounting columns 53; a plurality of arc strips 52 are evenly distributed on the mounting strips 51 along the length of the mounting strips 51 and are all concave towards the pipe hook 4; a plurality of nozzles 54 are evenly distributed on the arc strips 52 along the arc surface extension direction and are all connected to the water pipes 55; one end of the water pipe 55 passes through the mounting columns 53 and the side wall of the cooling box 2 and is connected to the first water-cooled water supply device 8. By combining mounting strips 51, arc-shaped strips 52, mounting columns 53, nozzles 54, and water pipes 55, cold water is supplied to the water pipes 55 using the first water-cooling supply device 8. The cold water passes through the water pipes 55 and each nozzle 54, converging in an arc shape to spray the pipes. Compared with direct spraying, this ensures that the spray water can evenly cover the surface of the pipes, avoiding quality problems caused by uneven cooling, increasing the spraying area, making the spraying more uniform, and improving the quality and efficiency of pipe cooling.

[0040] For simplified manufacturing and design, the first arc-shaped spray assembly 5 is identical to the second arc-shaped spray assembly 6. Both the first arc-shaped spray assembly 5 and the second arc-shaped spray assembly 6 are connected to the first water-cooled water supply device 8 and the second water-cooled water supply device 9, respectively. Since the first arc-shaped spray assembly 5 and the second arc-shaped spray assembly 6 are the same size and specifications, manufacturing and design are simpler, requiring only one assembly method to complete application assembly, thus saving costs.

[0041] In this embodiment, the first water-cooled water supply device 8 includes a first water supply tank 81 and a first water pump 82; the first water supply tank 81 is connected to the first arc-shaped spray assembly 5 through the first water pump 82; the second water-cooled water supply device 9 includes a second water supply tank 91 and a second water pump 92; the second water supply tank 91 is connected to the second arc-shaped spray assembly 6 through the second water pump 92. The design of the first water-cooled water supply device 8 and the second water-cooled water supply device 9 enables the supply of cold water to the first water-cooled cooling chamber 21 and the second water-cooled cooling chamber 22, which is beneficial for the rapid cooling of the pipes.

[0042] Based on the above embodiment, the bottom end of the cooling box 2 has a water collection trough 10 corresponding to the lower part of the pipe hook 4; the water collection trough 10 extends in the front-rear direction relative to the cooling box 2; the front end of the water collection trough 10 is higher than its rear end; a water collection tank 11 is connected to the lower part of the rear end of the water collection trough 10. The cooling box 2 also has a third water cooling chamber 23 connected to the second water cooling chamber 22; specifically, the water collection trough 10 passes through the first water cooling chamber 21, the second water cooling chamber 22 and the third water cooling chamber 23 in sequence. Two third arc spray assemblies 7 are connected to the cooling box 2, which are located on both sides of the pipe hook 4 and within the third water cooling chamber 23; the third arc spray assembly 7 is connected to the water collection tank 11 through a third water pump 12; the third arc spray assembly 7 is the same as the first arc spray assembly 5. The system utilizes a water collection tank 10 and a water collection container 11 to recover cold water. A third water pump 12 then draws water from the water collection container 11 to a third arc-shaped spray assembly 7. The third arc-shaped spray assembly 7 further sprays cooling water onto the pipes, accelerating cooling and recycling water resources, thereby shortening the cooling time and providing more uniform cooling. Combined with the first arc-shaped spray assembly 5 and the second arc-shaped spray assembly 6, this system improves the efficiency and quality of cooling the plastic pipes, enhancing its practicality. However, it should be noted that the spray system formed by the third arc-shaped spray assembly 7, the third water pump 12, and the water collection container 11 is designed for flexible use; the structure should be used appropriately based on specific needs.

[0043] In order to achieve a good filtration and separation effect and prevent debris from entering the water collection tank 10, a filter separation net 13 is laid at the upper opening of the water collection tank 10.

[0044] In addition, the pipe track conveyor line 3 and the control system of the cooling and forming device for producing the polymer PE pipe are general standard parts or components known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. The specific implementation of this application may involve the use of software, but the software used is the most commonly used software by those skilled in the art and is not within the scope of protection of the claims of this patent application.

[0045] In summary, this utility model provides a cooling and forming apparatus for producing polymer PE pipes, which has the following advantages:

[0046] 1. By designing the pipe track conveyor line 3 horizontally at the top of the cooling box 2, and using the pipe hook frame 4 to support the pipes to move sequentially in the first water cooling chamber 21 and the second water cooling chamber 22, the area of ​​the pipes obstructed is small, thereby increasing the spray area and effectively reducing the problem of the pipes being obstructed by the pipe track conveyor line 3 during the cooling process, resulting in more uniform spray cooling of the pipes.

[0047] Second, a first arc-shaped spray assembly 5, a second arc-shaped spray assembly 6, and a third arc-shaped spray assembly 7 are designed sequentially in the first water-cooling chamber 21, the second water-cooling chamber 22, and the third water-cooling chamber 23, respectively. The three components supply cold water at different temperatures for spraying. The design is circumferential and arc-shaped. Compared with direct spraying, this ensures that the spray water can evenly cover the surface of the pipe, avoids quality problems caused by uneven cooling, increases the spraying area, makes the spraying more uniform, and improves the quality and efficiency of pipe cooling.

[0048] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
