Specific embodiments

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0023] The following gives specific embodiments.

[0024] Please refer to Figures 1-4As shown in the figure, a forming and cooling device for PVC threading pipes includes a water tank 11. A water pump 12 is fixedly connected to the side of the water tank 11. The water inlet end of the water pump 12 is fixedly connected to a water inlet pipe 13, and the water inlet pipe 13 is inserted into the interior of the water tank 11. A storage body 15 is fixedly connected to the top of the water tank 11. A plurality of support rings 16 are fixedly connected to the inner side wall of the storage body 15. Through holes are formed on both sides of the storage body 15. A plurality of fixing seats 17 are provided on the support rings 16. The plurality of fixing seats 17 are arranged in a ring on the support rings 16. A spray head 18 is fixedly connected to the fixing seat 17. A flexible pipe 14 is fixedly connected to the spray head 18, and the flexible pipe 14 is fixedly connected to the output end of the water pump 12. During use, the water pump 12 extracts cooling water from the water tank 11 through the water inlet pipe 13 and conveys it to the flexible pipe 14, and then conveys and distributes it to each spray head 18 through the flexible pipe 14. The PVC threading pipe enters from the through holes on the side of the storage body 15 and enters the middle of the support rings 16. Then, relying on a plurality of spray heads 18 distributed in a ring, the PVC threading pipe located in the middle is cooled together, so as to improve the cooling uniformity and reduce the defects caused by uneven cooling, especially for large-diameter PVC threading pipes.

[0025] Further, as Figures 1-2 shown, an opening is formed on the side of the storage body 15. A storage door 21 is hinged at the opening. An observation glass 22 is fixedly connected to the storage door 21. The plurality of support rings 16 and spray heads 18 are located inside the storage body 15. During use, since the sprayed cooling water has a certain pressure and is distributed in a ring, the cooling water will splash everywhere. By providing the storage body 15 above the water tank 11 and the hinged and closable storage door 21, and the spray heads 18 are located inside the storage body 15, it can play a role in blocking the cooling water, thereby reducing the splashing of the cooling water and reducing waste. The observation glass 22 is used to conveniently observe the interior of the storage body 15.

[0026] Further, as Figures 4-5As shown in the figure, an annular slide rail 34 is fixedly connected to the support ring 16. The fixed seat 17 is slidably connected to the annular slide rail 34. A rotating shaft 31 is rotatably connected to the fixed seat 17. One end of the rotating shaft 31 is fixedly connected with a cam 32, and the other end of the rotating shaft 31 is fixedly connected with a handle. A rubber pad 33 is fixedly connected to the cam 32. When the rotating shaft 31 is rotated, the rotating shaft 31 drives the cam 32 to press the rubber pad 33 against the surface of the annular slide rail 34. In use, when cooling large-diameter PVC threading pipes, it is necessary to correspondingly increase the number of nozzles 18 and adjust the positions of the nozzles 18. In this embodiment, a plurality of nozzles 18 are slidably connected to the support ring 16 through the annular slide rail 34, and their positions can be adjusted by rotation according to requirements. Then, the nozzles 18 on the fixed seat 17 can be increased or decreased according to requirements. After the position adjustment of the fixed seat 17 is completed, by rotating the handle, the rotating shaft 31 and the cam 32 are rotated, and the cam 32 rotates to press the rubber pad 33 against the surface of the annular slide rail 34 to fix it.

[0027] Further, as Figures 2-3 shown, a support 41 is fixedly connected to the inner side wall of the bin body 15 at a position corresponding to the through hole. A pair of supports 42 are arranged above the support 41. A cotton wheel 43 is rotatably connected to the support 42. In use, the support 41 and the support 42 are used to fix the cotton wheel 43. The PVC threading pipe passes between the two cotton wheels 43. Relying on the two cotton wheels 43 can play a role in wiping and absorbing water from the PVC threading pipe, thereby reducing the water stains on the surface of the PVC threading pipe, further reducing the wetting of the working ground, and reducing the waste of cooling water.

[0028] Further, as Figures 2-3 shown, the bottom of a pair of the supports 42 is slidably connected to a base 51. The base 51 is fixedly connected to the support 41. A screw 52 is rotatably connected to the base 51. The screw 52 passes through the support 42 and is threadedly connected thereto. When the screw 52 is rotated, the screw 52 can make the two bases 51 approach each other. In use, the staff can rotate and adjust the screw 52 according to the thickness of the PVC threading pipe. The thread directions at both ends of the screw 52 are opposite, so as to drive the fixed seat 17 to move inside the bottom, so that they move away from or approach each other, so as to adjust the distance between the two cotton wheels 43.

[0029] Further, as Figure 2 shown, a filter cylinder 61 is threadedly connected to the end of the water inlet pipe 13. A water baffle 62 is fixedly connected to the top of the water tank 11. The water baffle 62 is inclined and located on the side of the filter cylinder 61. In use, the filter cylinder 61 can filter the cooling water sucked by the water pump 12, thereby reducing the situation that the nozzles 18 are blocked. The water baffle 62 is used to play a blocking role, and the pollutants floating on the water surface will be blocked.

[0030] Furthermore, as Figure 3 shown, a scraping rod 7 is fixedly connected to the side surface of the fixing base 17. The scraping rod 7 is in contact with the surface of the cotton wheel 43. During use, by means of the arranged scraping rod 7, the cotton wheel 43 can be extruded, so as to squeeze out the water in the cotton wheel 43, which is convenient for the cotton wheel 43 to wipe the surface of the PVC threading pipe.

[0031] Working principle: During use, the water pump 12 extracts cooling water from the water tank 11 through the water inlet pipe 13 and conveys it to the flexible pipe 14, and then conveys and distributes it to each nozzle 18 through the flexible pipe 14. The PVC threading pipe enters from the through hole on the side surface of the bin body 15 and enters the middle of the support ring 16. Then, relying on a plurality of nozzles 18 distributed in a ring, the PVC threading pipe located in the middle is cooled jointly, so as to improve the cooling uniformity and further reduce the defects caused by uneven cooling. Especially for large-diameter PVC threading pipes, because the sprayed cooling water has a certain pressure and is distributed in a ring, the cooling water will splash everywhere. By arranging the bin body 15 and the hinged and closable bin door 21 above the water tank 11, and the nozzles 18 are located inside the bin body 15, it can play a role in blocking the cooling water, so as to reduce the splashing of the cooling water and reduce waste. The observation glass 22 is used to conveniently observe the inside of the bin body 15. During use, when cooling large-diameter PVC threading pipes, it is necessary to correspondingly increase the number of nozzles 18 and adjust the positions of the nozzles 18. In this embodiment, a plurality of nozzles 18 are slidably connected to the support ring 16 through a circular slide rail 34, and they can be rotated according to requirements to adjust the positions of the nozzles 18. Then, according to requirements, the nozzles 18 on the fixing base 17 are increased or decreased. After the position of the fixing base 17 is adjusted, by rotating the handle, the rotating shaft 31 and the cam 32 are rotated, and the cam 32 rotates to squeeze the rubber pad 33 against the surface of the circular slide rail 34 to fix it. The brackets 41 and the supports 42 are used to fix the cotton wheels 43. The PVC threading pipe passes between the two cotton wheels 43. Relying on the two cotton wheels 43 can play a role in wiping and absorbing water from the PVC threading pipe, so as to reduce the water stains on the surface of the PVC threading pipe, further reduce wetting the working ground, and reduce the waste of cooling water. During use, the staff can rotate and adjust the screw rod 52 according to the thickness of the PVC threading pipe. The thread directions at both ends of the screw rod 52 are opposite, so as to drive the fixing base 17 to move inside the bottom, so that they move away from or close to each other, so as to adjust the distance between the two cotton wheels 43. The filter cartridge 61 can filter the cooling water inhaled by the water pump 12, so as to reduce the situation that the nozzles 18 are blocked. The water baffle 62 is used to play a blocking role, and the pollutants floating on the water surface will be blocked.
