Description

Technical Field

[0001] This utility model relates to the field of spray boxes, and in particular to a cooling spray box for PVC pipe production. Background Technology

[0002] PVC pipe is short for polyvinyl chloride pipe. It is a pipe made from polyvinyl chloride resin as the main raw material, with the addition of appropriate additives, through extrusion or injection molding. In the production process of PVC pipe, a cooling spray box is needed to cool and shape the extruded PVC pipe. When the PVC pipe enters the cooling spray box, the spray system sprays the cooling medium evenly onto the surface of the PVC pipe. Through heat exchange, the surface temperature of the PVC pipe drops rapidly. Then, the cooling medium absorbs heat and its temperature rises. Under the action of the circulation system, it returns to the bottom of the box, is cooled again, and is then transported back to the spray system to continue cooling the PVC pipe. Through this cyclic cooling method, the PVC pipe reaches the required cooling temperature when it leaves the cooling spray box, completing the shaping process.

[0003] Most existing cooling spray boxes use fixed nozzles, which may lead to inconsistent cooling rates on different parts of the PVC pipe surface. For example, excessive nozzle spacing or angle deviation may result in insufficient cooling water in some areas of the pipe, while other areas are over-cooled, causing uneven cooling of the pipe. This leads to inconsistent shrinkage on different parts of the PVC pipe surface, resulting in an uneven surface, affecting the appearance quality, dimensional accuracy, and performance stability of the pipe.

[0004] Therefore, since most of the existing cooling spray boxes use fixed nozzles, which may lead to inconsistent cooling rates on different parts of the PVC pipe surface, resulting in uneven cooling of the pipe and affecting the appearance quality, dimensional accuracy, and performance stability of the pipe, a cooling spray box for PVC pipe production can be designed with adjustable support components to drive the nozzles to adjust their angle. Utility Model Content

[0005] To overcome the problem that most existing cooling spray boxes use fixed nozzles, which may cause inconsistent cooling rates on different parts of the PVC pipe surface, resulting in uneven cooling of the pipe and affecting the appearance quality, dimensional accuracy, and performance stability of the pipe.

[0006] The technical solution of this utility model is as follows: a PVC pipe production cooling spray box, including a box body; a water supply tank for providing cold water for spraying is fixedly connected to the upper corner of the box body; a support plate is fixedly connected to the upper inner side of the box body; a slidable scraper is attached to the bottom inner side of the box body; a water outlet pipe passing through the box body is fixedly connected to one end of the water supply tank; a water storage main pipe is fixedly connected to the end of the water outlet pipe away from the water supply tank; multiple sets of spray pipes are horizontally fixedly connected to the lower end of the water storage main pipe; a fixing ring is fitted around the outside of the spray pipe; a rotating ring is horizontally fixedly installed on the support plate corresponding to the spray pipe; a drive motor is installed on the upper end of the rotating ring; a rotating shaft is fixedly connected to the output end of the drive motor; a U-shaped frame is fixedly connected to the lower end of the rotating shaft; a first rotating motor is installed on one side of the U-shaped frame; a rotating column is fixedly connected to the output shaft of the first rotating motor; a connecting block is provided below the U-shaped frame; and the fixing ring is fixedly connected to the connecting block.

[0007] Furthermore, the box has symmetrical perforations at both ends, and an arc-shaped perforated plate is fixed to the inside of the box below the perforations. The inner walls of the box have symmetrical strip grooves on the lower sides.

[0008] Furthermore, a connecting shaft is horizontally inserted through the upper side of one side of the box, and a sealing plate is provided on one side of the box. The sealing plate is rotatably connected to the box through the connecting shaft, and a handle is fixedly attached to the side of the sealing plate away from the connecting shaft.

[0009] Furthermore, a cooler is installed inside the water supply tank, a water pump is installed at one corner of the water supply tank, and an inlet pipe is fixedly connected at the upper corner of the water supply tank.

[0010] Furthermore, a circulating water pipe is fixedly connected to the end of the water supply tank away from the outlet pipe. The end of the circulating water pipe away from the water supply tank passes through the tank body. A circulating pump is installed at the connection between the circulating water pipe and the tank body. A filter is installed inside the end of the circulating water pipe away from the water supply tank.

[0011] Furthermore, the connecting block is rotatably connected to the U-shaped frame via a rotating column.

[0012] Furthermore, two sets of second rotating motors are longitudinally installed at one end of the housing. The output end of the second rotating motor is fixedly connected to a threaded rod. The threaded rod is rotatably installed on the housing through a bearing and is set along the extension direction of the strip groove. A rectangular threaded sleeve that is fixedly connected to the scraper is sleeved on the outside of the threaded rod.

[0013] The beneficial effects of this utility model are as follows: The rotating shaft and rotating column on the support plate work together to flexibly drive the spray pipe to change direction and angle in all directions. Based on this innovative dynamic spraying mechanism, the pipe can receive sprayed cold water evenly all over its body, ensuring that the cooling amount received by each part of the pipe is balanced during the cooling process. From the perspective of improving pipe quality, the above-mentioned uniform cooling method makes the shrinkage degree of each part of the PVC pipe consistent, effectively avoiding defects such as unevenness and wrinkles on the pipe surface caused by differences in cooling speed. This not only significantly improves the surface flatness of the pipe, giving it a smooth and delicate appearance, and greatly optimizes the visual effect and aesthetics of the pipe, but also ensures that the dimensional accuracy of the pipe is maintained at a very high level. The precise dimensional accuracy provides a solid guarantee for the tight and accurate fit of the pipe with various pipe fittings during subsequent installation and use, thereby effectively ensuring the performance stability and reliability of the pipe in actual application scenarios, and greatly reducing engineering hazards and economic losses caused by pipe quality defects.

During this process, the rotating shaft 303 and the rotating column 306 on the support plate 3 rotate, driving the spray water pipe to change direction and angle, so that the pipe is cooled evenly. The cold water with increased temperature is circulated through the circulating water pipe 207 on one side of the water supply tank 2 and reused.

[0022] Please see Figures 1-2 In this embodiment, the box body 1 has symmetrical perforations 101 at both ends. An arc-shaped hole placement plate 102 is fixedly connected to the inner side of the box body 1 below the perforations 101. The inner wall of the box body 1 has symmetrical strip grooves 103 on both sides below. The pipe to be cooled and shaped is passed horizontally through the perforations 101 through the box body 1 and placed on the arc-shaped hole placement plate 102.

[0023] Please see Figure 2 In this embodiment, a connecting shaft 104 is horizontally inserted above one side of the housing 1, and a sealing plate 105 is provided on one side of the housing 1. The sealing plate 105 is rotatably connected to the housing 1 through the connecting shaft 104. A handle 106 is fixedly connected to the side of the sealing plate 105 away from the connecting shaft 104. After a period of use, the handle 106 can be pulled, and the sealing plate 105 can be rotated and opened through the connecting shaft 104 to facilitate the operator to enter the housing 1 for maintenance.

[0024] Please see Figure 3 In this embodiment, a cooler is provided inside the water supply tank 2, a water pump 201 is installed at one corner of the water supply tank 2, and an inlet pipe 202 is fixedly connected at the upper corner of the water supply tank 2. Cold water is poured into the water supply tank 2 through the inlet pipe 202, and the cooler is activated to maintain the low temperature of the cold water.

[0025] Please see Figure 3 In this embodiment, a circulating water pipe 207 is fixedly connected to the end of the water supply tank 2 away from the outlet pipe 203. The end of the circulating water pipe 207 away from the water supply tank 2 passes through the tank body 1. A circulating pump 208 is provided at the connection between the circulating water pipe 207 and the tank body 1. A filter 209 is installed inside the end of the circulating water pipe 207 away from the water supply tank 2.

At the same time, driven by the circulating pump 208, the heated cold water enters the circulating water pipe 207 and returns to the water supply tank 2.

[0026] Please see Figure 4 In this embodiment, the connecting block 307 is rotatably connected to the U-shaped frame 304 via the rotating column 306. Driven by the first rotating motor 305, the connecting block 307 is rotatably connected to the U-shaped frame 304 via the rotating column 306.
