Description

Technical Field

[0001] This utility model relates to the technical field of cooling and shaping devices, specifically to a high-efficiency spray cooling and shaping device for CPVC pipes. Background Technology

[0002] CPVC is a new type of engineering plastic with broad application prospects. The resin is obtained by chlorination modification of polyvinyl chloride (PVC) resin. It is a new type of engineering plastic. The product is a white or light yellow, tasteless, odorless, and non-toxic loose granules or powder. After chlorination, the irregularity of molecular bonds and polarity of PVC resin increase, which increases the solubility and chemical stability of the resin. This improves the material's heat resistance, resistance to corrosion from acids, alkalis, salts, oxidants, etc., and makes it widely used in various industrial fields.

[0003] According to Chinese patent number CN 222061193 U, a PVC pipe shaping and cooling device is disclosed. This device includes an electric cylinder installed at the bottom of a water tank. The output end of the electric cylinder passes through the water tank and connects to a movable plate. A fixing rod is installed on the surface of the movable plate. Several slots are formed on the surface of the movable plate, and several slots are formed on one side of each slot. A rod is installed on the surface of one or two slots. An automatic bending mechanism is installed on the surface of the movable plate. This device, through the use of the water tank, electric cylinder, movable plate, slots, and slots, can quickly cool and shape the pipe. The water in the tank can be reused repeatedly, and it is applicable to pipes of different sizes, improving its applicability and practicality.

[0004] The tube shaping and cooling device described above, through the coordinated use of a water tank, electric cylinder, moving plate, slot one, and slot two, can quickly cool and shape the processed tubes, improving practicality. However, in actual use, the circular motion of the rotating rod, combined with the handheld heating gun, to heat and bend the bent parts of the tube requires a high degree of skill; otherwise, deformation of the bent parts of the tube will inevitably occur, affecting processing efficiency. Secondly, after the tubes are processed by this device, the moving plate controlled by the electric cylinder needs to be placed in the water tank for cooling after processing. However, if the tubes are light, they may not be able to fully enter the water for cooling. Furthermore, if cooling is performed after processing is completed, the tubes may spring back, affecting processing accuracy. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the problem that the existing pipe shaping and cooling device uses a rotating rod in circumferential motion in conjunction with a handheld heating gun to heat and bend the bent part of the pipe, which requires skilled movement and also affects the processing efficiency.

[0006] The technical solution adopted to solve the above technical problems is:

[0007] A high-efficiency spray cooling and shaping device for CPVC pipes includes a circulating water tank, a lifting mechanism, a lifting platform, and a rotating mechanism. The lifting mechanism and the lifting platform are both located inside the circulating water tank, and the rotating mechanism is located on top of the circulating water tank. A pressure wheel is rotatably connected to the output end of the rotating mechanism. A matching heat-conducting arc plate is provided on the inner side of the pressure wheel, and heating elements are evenly arranged on the outer wall of the heat-conducting arc plate for heating the heat-conducting arc plate. The rotating mechanism controls the pressure wheel to move in a circular motion around the central axis of the heat-conducting arc plate. A matching mold seat is provided at the entrance of the heat-conducting arc plate to prevent material deviation during processing.

[0008] As a preferred embodiment of the present invention, the rotating mechanism includes a drive device fixedly installed on the top of the circulating water tank. The output end of the drive device passes through the circulating water tank and extends into its interior. The output end of the drive device is connected to a connecting plate. The far end of the connecting plate is connected to a fixed shaft. The pressure wheel is rotatably connected to the shaft wall of the fixed shaft.

[0009] As a preferred embodiment of this utility model, the upper end of the fixed shaft is connected to a mounting plate, the far end of the mounting plate is connected to a head spray, and the input end of the head spray is connected to a water inlet pipe.

[0010] As a preferred technical solution of this utility model, the head spray is set on the outer side near the inlet end of the heat-conducting arc plate to pre-shape the heated and bent material.

[0011] As a preferred technical solution of this utility model, the top of the lifting platform is provided with a water inlet, and the top of the lifting platform is provided with a limiting strip for restricting the sinking of materials, and the limiting strip is fixedly connected to the lifting platform.

[0012] As a preferred embodiment of this utility model, the outer wall of the circulating water tank is provided with a retrieval port, and the retrieval port is located above the water level inside the circulating water tank.

[0013] As a preferred technical solution of this utility model, the lifting mechanism includes a telescopic cylinder and a limiting rod. The telescopic cylinder is fixedly connected to the bottom of the circulating water tank. The output end of the telescopic cylinder passes through the circulating water tank and is connected to the bottom of the lifting platform, controlling the lifting platform to move vertically up and down along the inside of the circulating water tank. The limiting rod is fixedly connected to the bottom of the lifting platform, and the lower end of the limiting rod passes through the circulating water tank and extends below it.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention uses a drive device to drive a pressure wheel to rotate around a heat-conducting arc plate, which can smoothly and evenly bend and shape the heated and softened pipe. It completely replaces the outdated operation method in the prior art that requires manual operation of a heating gun and a rotating rod to heat and bend at the same time. This structure effectively eliminates problems such as deformation and unstable quality of the pipe at the bending point caused by insufficient manual skills, significantly improves processing accuracy and production efficiency, and reduces the difficulty of operation and dependence on skilled workers.

[0016] This invention innovatively adopts a phased cooling and shaping scheme that combines spray cooling and immersion cooling. By installing a spray nozzle on a fixed shaft located outside the inlet of the heat-conducting arc plate, the newly bent pipe section can be sprayed immediately to achieve initial shaping and effectively prevent the pipe from rebounding due to the elastic memory effect. Subsequently, the lifting mechanism controls the lifting platform to smoothly lower the pipe into the cooling water in the circulating water tank for overall immersion cooling. The limit bar at the top of the lifting platform ensures that the pipe is completely submerged and in a fixed position. This process of first locally and quickly shaping and then fully cooling the whole overcomes the defects of uneven cooling, pipe deformation or rebound that may occur when uniform cooling is performed after processing in the prior art, ensuring the final shaping quality and dimensional stability of the CPVC pipe.

[0027] Example 1

[0028] exist Figures 1-4This utility model provides a technical solution: a high-efficiency spray cooling and shaping device for CPVC pipes, including a circulating water tank 1, a lifting mechanism 2, a lifting platform 3, and a rotating mechanism. The circulating water tank 1 can be connected to an external water source via a pump to achieve water circulation within the tank, ensuring stable water temperature. This is prior art. The lifting mechanism 2 and the lifting platform 3 are both located inside the circulating water tank 1, and the rotating mechanism is located on top of the circulating water tank 1. A guide gap exists between the top of the circulating water tank 1 and the lifting platform 3 for the output end of the rotating mechanism to be rotatably connected to a pressure wheel. The pressure roller 7 makes a circular motion, and a matching heat-conducting arc plate 5 is provided on the inner side of the pressure roller 7. Heating plates 6 are evenly arranged on the outer wall of the heat-conducting arc plate 5. Electric heating is commonly used in the market. After the heating plates heat up, they conduct heat to the heat-conducting arc plate 5. The heat-conducting arc plate 5 then transfers the heat to the surface of the material it is in contact with, making the surface of the material soft. In conjunction with the rotation mechanism, the pressure roller 7 is controlled to make a circular motion around the central axis of the heat-conducting arc plate 5, thereby causing the material to slowly bend around the inner wall of the heat-conducting arc plate 5, realizing automatic bending. Compared with the existing technology, it is more automated and improves production efficiency and quality.

[0029] Meanwhile, a matching mold seat 15 is provided at the entrance of the heat-conducting arc plate 5. Before processing, the tube is placed on the mold seat 15, so that the pressure roller 7 controls the bending of the material and the processing position does not shift.

[0030] In one aspect of this embodiment, the rotating mechanism specifically includes a drive device 9, such as a motor, fixedly installed on the top of the circulating water tank 1. The output end of the drive device 9 passes through the circulating water tank 1 and extends into its interior. The output end of the drive device 9 is connected to a connecting plate 8. The far end of the connecting plate 8 is connected to a fixed shaft 10. The pressure roller 7 is rotatably connected to the shaft wall of the fixed shaft 10. The drive device 9 controls the connecting plate 8 and the fixed shaft 10 to drive the pressure roller 7 to move in a ring motion, thereby controlling the degree of bending of the pipe material.

[0031] In one aspect of this embodiment, a mounting plate 11 is connected to the upper end of the fixed shaft 10, and a head spray 12 is connected to the far end of the mounting plate 11. The input end of the head spray 12 is connected to a water inlet pipe 13, so that during processing, the part of the tube material that has been bent first is initially shaped by the spray head 12 to prevent the material from rebounding and improve the processing quality. The spray head 12 can be connected to an external water pump to increase the water source in the water tank. The head spray 12 is set on the outside near the inlet end of the heat-conducting arc plate 5 to initially shape the heated and bent material.

[0032] In one aspect of this embodiment, a water inlet 4 is provided at the top of the lifting platform 3, so that the lifting platform 3 will not generate negative pressure during the lifting and lowering of the water tank, making the lifting and lowering more stable than the prior art. The top of the lifting platform 3 is provided with a limiting baffle 14 for restricting the sinking of materials. The limiting baffle 14 is fixedly connected to the lifting platform 3. During the lifting and lowering, the materials are limited to the top of the lifting platform 3 by the limiting baffle 14. As the lifting platform 3 moves into the water tank, comprehensive cooling is achieved.

[0033] In one aspect of this embodiment, the outer wall of the circulating water tank 1 is provided with a retrieval port 16, and the retrieval port 16 is located above the water level inside the circulating water tank 1.

[0034] In one aspect of this embodiment, the lifting mechanism 2 specifically includes a telescopic cylinder 21 and a limiting rod 22. The telescopic cylinder 21 is fixedly connected to the bottom of the circulating water tank 1. The output end of the telescopic cylinder 21 passes through the circulating water tank 1 and is connected to the bottom of the lifting platform 3, controlling the lifting platform 3 to move vertically up and down along the interior of the circulating water tank 1. The limiting rod 22 is fixedly connected to the bottom of the lifting platform 3. The lower end of the limiting rod 22 passes through the circulating water tank 1 and extends below it. The limiting rod 22 further improves the stability of the movement of the lifting platform 3.

[0035] The specific operating principle of the high-efficiency spray cooling and shaping device for CPVC pipes described in this utility model is as follows: First, the CPVC pipe to be processed is inserted into the mold seat 15 for positioning to ensure that it does not shift during subsequent processing. The device is then started, and the heating element 6 begins to work, transferring heat to the heat-conducting arc plate 5, raising its temperature and uniformly heating and softening the pipe parts in contact with it. Subsequently, the drive device 9 is started, driving the connecting plate 8 to rotate, which in turn causes the pressure roller 7 to rotate around the central axis of the heat-conducting arc plate 5 via the fixed shaft 10. The pressure roller 7 continuously applies pressure to the softened pipe, forcing it to tightly adhere to the inner wall contour of the heat-conducting arc plate 5, thereby achieving smooth bending and shaping of the pipe. This process is fully automated, replacing the unstable operation of the traditional manual handheld heating gun. Immediately after the material is bent and formed, the head spray 12 located at the far end of the mounting plate 11 on the fixed shaft 10 starts to work. The head spray 12 is connected to the cooling water through the water inlet pipe 13 and sprays the part of the pipe that has just been bent precisely to achieve rapid preliminary cooling and shaping. This instant cooling step effectively prevents the rebound of the pipe due to the material memory effect and ensures the accuracy of the bending angle. After a section of the pipe is bent and preliminarily shaped, the lifting mechanism 2 starts to move. The telescopic cylinder 21 retracts the lifting platform 3 and moves it vertically downward along the inside of the circulating water tank 1, so that the bent part of the pipe is immersed in the cooling water of the circulating water tank 1. The water outlet 4 at the top of the lifting platform 3 ensures that the lifting process is smooth, while the limit bar 14 prevents the pipe from shifting or floating in the cooling water, ensuring that it is completely submerged for sufficient and uniform final cooling and shaping.

[0036] After cooling is complete, the telescopic cylinder 21 unfolds, driving the lifting platform 3 and the pipe to move to the initial position to retrieve the material. Or, before it is raised, the operator can also take out the processed pipe through the retrieval port 16 on the outer wall of the circulating water tank 1. The entire processing process integrates automatic heating and bending, instant spraying and shaping, and overall immersion cooling, which significantly improves processing efficiency and product quality.

[0037] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
