They are among the earliest plastic pipes developed and applied. During the PVC pipe production process, the PVC pipes produced by the extruder need to be cooled and shaped by a cooling device, which necessitates the use of a shaping production device.

[0019] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] like Figure 1 and Figure 3 As shown, a forming production device for PVC pipe production includes a water-cooled outer frame 1, a water-cooled cavity 2 and an air guide component 7. The water-cooled outer frame 1 is provided with a water-cooled cavity 2, and heat dissipation fins 6 are fixed in the middle of the front and rear sides of the water-cooled outer frame 1. The inner side of the water-cooled cavity 2 is connected to an annular water spray pipe 4 through a connecting water pipe 3, and the inner side of the annular water spray pipe 4 is evenly distributed with spray nozzles 5. The water-cooled cavity 2 is interconnected with the inner side of the annular water spray pipe 4 through the connecting water pipe 3, and the annular water spray pipes 4 are equidistantly distributed, and the transverse center line of the annular water spray pipe 4 coincides with the transverse center line of the water-cooled outer frame 1. A mounting seat 8 is provided below the water-cooled outer frame 1, and a hollow bearing plate 9 is fixed in the middle of the mounting seat 8. A water storage tank 10 is fixed below the mounting seat 8, and a water storage tank 10 is installed below the water storage tank 10. It is equipped with a support column 11; after the PVC pipe is discharged, it can be located in the middle of the inside of the water-cooled outer frame 1 and pass through the water-cooled outer frame 1. At this time, the low temperature environment inside the water-cooled outer frame 1 due to the water-cooling and air-cooling structure can promote the initial cooling of the PVC pipe. The cooling water inside the water-cooling cavity 2 can enter the inside of the annular water spray pipe 4 through the connecting water pipe 3, and is sprayed through the spray nozzles 5 evenly distributed in an annular radial shape, so as to evenly spray and cool the outside of the PVC pipe. The sprayed water flow can flow out of the water-cooling outer frame 1 and flow out through the hollow supporting plate 9 to the inside of the water storage tank 10 below, so as to facilitate the subsequent purification and cooling of this part of the water body and then return it to the water-cooling cavity 2 of the water-cooling outer frame 1 through the water pump for recycling. At the same time, the heat dissipation fins 6 facilitate heat dissipation of the water body in the water-cooling cavity 2.

[0021] like Figure 1-Figure 3As shown, an air guide assembly 7 is installed around the water-cooling outer frame 1, and the air guide assembly 7 includes an air guide cavity 701, a ventilation net 702, a connecting air duct 703, an air extraction pump 704 and an air cooling chamber 705. The air guide cavity 701 is located around the inner side of the water-cooling outer frame 1, and a ventilation net 702 is installed on the side of the air guide cavity 701 close to the inner center line of the water-cooling outer frame 1, a connecting air duct 703 is installed on the outer side of the air guide cavity 701, and an air extraction pump 704 is installed at the end of the connecting air duct 703, and an air cooling chamber 705 is installed on the other side of the air extraction pump 704, and the air cooling chamber 705 is respectively located on the upper and lower sides of the water-cooling outer frame 1, the air guide assembly 7 also includes an air supply pump 706, and an air supply pump 706 and a connecting air duct 703 are installed on the other side of the air cooling chamber 705, and the connecting air duct 703 and the air guide cavity 701 are connected to each other. The water-cooling chamber 2 and the inner side surface of the air-guiding air chamber 701 form a circular structure, and there are four air-guiding air chambers 701 symmetrically distributed; the air pump 704 on the right and the connecting air duct 703 are used to conveniently pump the air flowing in the air-guiding air chamber 701 into the interior of the air-cooling chamber 705. The air-cooling chamber 705 is equipped with a cooling structure to cool the incoming air flow, and the air supply pump 706 on the left and the connecting air duct 703 are used to facilitate the cooled air flow to be sent into the interior of the air-guiding air chamber 701. On the one hand, the cold air in the air-guiding air chamber 701 overflows through the ventilation net 702 to cool the PVC pipe in the middle of the water-cooling outer frame 1. On the other hand, the air flow inside the four air-guiding air chambers 701 can take away heat during the flow, thereby cooperating with the water-cooling structure to fully cool the PVC pipe to promote the production and shaping of the PVC pipe.

[0022] In summary, if Figure 1-Figure 3As shown, the shaping production device for PVC pipe production can be used. When the PVC pipe produced by the extruder is used, the PVC pipe material produced by the extruder can be located in the middle of the water-cooled outer frame 1 after being discharged and pass through the water-cooled outer frame 1 from left to right. At this time, the low temperature environment inside the water-cooled outer frame 1 due to the water-cooling and air-cooling structure can promote the initial cooling of the PVC pipe. In this process, the cooling water inside the water-cooling cavity 2 can enter the interior of the annular water spray pipe 4 through the connecting water pipe 3, and be sprayed out through the spray nozzles 5 evenly distributed in an annular radial shape, so as to evenly spray and cool the outside of the PVC pipe. At the same time, the air flowing in the air guide cavity 701 can be pumped to the interior of the air cooling chamber 705 through the exhaust pump 704 and the connecting air duct 703 on the right side. The built-in cooling structure can cool the incoming air flow, and then send the cooled air flow into the interior of the air guide cavity 701 through the air pump 706 and the connecting air duct 703 on the left, so that the heat can be taken away by the flowing wind while cooling the PVC pipe. The PVC pipe is fully cooled by the water cooling structure to promote the production and shaping of the PVC pipe. The sprayed water flow can flow out of the water-cooled outer frame 1 and flow out to the inside of the water storage tank 10 below through the hollow supporting plate 9, so that this part of the water body can be purified and cooled later and then returned to the water cooling cavity 2 of the water cooling outer frame 1 through the water pump for recycling, and the heat dissipation fins 6 can dissipate heat from the water in the water cooling cavity 2, thus completing the use process of the shaping production device for PVC pipe production.
