Description

Technical Field

[0001] The present invention relates to the technical field of plastic processing machinery, and more particularly to a processing device for HDPE water supply pipes. Background Art

[0002] HDPE water supply pipes, full name high-density polyethylene water supply pipes, are pipes made of high-density polyethylene materials. The HDPE water supply pipe processing equipment realizes the precise processing and shaping of HDPE raw materials through a series of precise mechanical components and control systems. These devices not only have a high degree of automation, can significantly improve production efficiency, but also ensure the quality and stability of products.

[0003] The HDPE water supply pipe processing equipment is a special equipment for producing HDPE water supply pipes. These devices usually include components such as an extruder, a die, a cooling device, a traction device, a cutting device, etc., and can complete the whole process from raw material addition to finished product output. When processing HDPE water supply pipes, it is necessary to continuously pull the extruded pipe out of the die through a traction device to maintain the continuity of the production process. Most traction devices use rubber block caterpillar tractors. Rubber blocks are installed on the caterpillar chains of the tractor, and these rubber blocks are installed on the chains by fixing methods such as screws. When the caterpillar chain rotates, the rubber blocks also move and clamp the HDPE water supply pipe. The tractor realizes the continuous traction and conveying of the pipe through the continuous rotation of the caterpillar chain. The tractor is usually equipped with a speed controller and a traction force adjustment device, and can accurately adjust the traction speed and traction force according to the specifications, dimensions and processing requirements of the pipe.

[0004] In the existing technical solutions, most are to drive the rubber blocks to move through the caterpillar chain, and the rubber blocks clamp the HDPE water supply pipe to perform traction processing on the HDPE water supply pipe. However, the clamping contact area of the rubber blocks on the water supply pipe is relatively limited, and it is impossible to wrap and clamp the water supply pipe well, thereby affecting the traction effect of the HDPE water supply pipe processing. Summary of the Invention

[0005] The purpose of the present invention is to provide a processing device for HDPE water supply pipes. Through the expansion of the traction hydraulic bladder facing the HDPE water supply pipe, the clamping area of the traction hydraulic bladder on the HDPE water supply pipe can be increased. At the same time, when the traction hydraulic bladder expands towards the HDPE water supply pipe side, a plurality of limiting blocks arranged in cooperation can limit the traction hydraulic bladder, so that the expansion surface of the traction hydraulic bladder fully fits on the clamping end face of the HDPE water supply pipe, thereby being able to wrap and clamp the HDPE water supply pipe well, further improving the clamping and traction effect, and solving the problems raised in the above background art.

The output end of the servo motor penetrates through the bearing top cover and is fixedly connected with a bidirectional lead screw. The bottom end of the bidirectional lead screw is rotatably connected with the bearing base.

[0009] Preferably, a nut is threadedly connected to the outer wall of the bidirectional lead screw. A bearing sleeve is fixedly installed outside the nut. The bearing sleeve is fixedly connected with the bearing cross frame. A supporting cross plate is fixedly installed between two adjacent bearing cross frames on the left and right.

[0010] Preferably, the traction and driving assembly further includes a motor fixedly installed at the top left end of the left bearing cross frame. The output end of the motor penetrates through the bearing cross frame and is fixedly connected with the driving shaft. A limiting dial block is fixedly installed on the outer side of the toothed belt. The number of the limiting dial blocks is multiple.

[0011] Preferably, a pressure regulating and temperature guiding assembly is arranged on the right side of the upper end surface of the bearing base. The pressure regulating and temperature guiding assembly includes a hydraulic pump fixedly installed on the right side of the upper end surface of the bearing base. The output end of the hydraulic pump is fixedly communicated with a hydraulic conduit.

[0012] Preferably, the pressure regulating and temperature guiding assembly further includes a pressure regulating and temperature guiding bladder respectively fixed at the middle positions of the lower end surface of the bearing top cover and the upper end surface of the bearing base. A limiting ring plate is attached to the outside of the pressure regulating and temperature guiding bladder. The limiting ring plate is respectively fixed at the surrounding positions of the lower end surface of the bearing top cover and the upper end surface of the bearing base.

[0013] Preferably, a cooling and shaping assembly is arranged at the left rear of the upper end surface of the bearing base. The cooling and shaping assembly includes a water pump fixed at the left rear end of the upper end surface of the bearing base. The output end of the water pump is fixedly communicated with an infusion water pipe.

[0014] Preferably, the cooling and shaping assembly further includes an assembly groove opened at the rear end of the bearing cross-frame. An assembly bearing is provided inside the assembly groove. The outer ring of the assembly bearing is fixedly installed on the outer wall of the assembly groove. A cooling water pipe is fixedly installed between the inner rings of the two assembly bearings. The cooling water pipe is rotatably connected to the output end of the infusion water pipe.

[0015] Preferably, torsion springs are fixedly installed at both ends of the cooling water pipe within the assembly groove. An adjusting block is fixedly installed on the right side of the outer wall of the cooling water pipe.

[0016] Preferably, the number of the cooling water pipes is two. Second spray holes are opened on the adjacent end faces of the two cooling water pipes. First spray holes are opened on the end faces of the cooling water pipes close to the traction hydraulic bladder. A water collecting tank corresponding to the cooling water pipes is fixedly installed at the rear end of the bearing base.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. Through the expansion of the traction hydraulic bladder facing the HDPE water supply pipe, the present invention can increase the clamping area of the traction hydraulic bladder on the HDPE water supply pipe. At the same time, when the traction hydraulic bladder expands towards the HDPE water supply pipe side, the multiple limiting blocks provided can limit the traction hydraulic bladder, enabling the expansion surface of the traction hydraulic bladder to fully fit on the clamping end face of the HDPE water supply pipe, thereby better wrapping and clamping the HDPE water supply pipe and further improving the clamping and traction effect.

[0019] 2. The traction hydraulic bladder of the present invention is filled with liquid. By the fitting and clamping of the traction hydraulic bladder on the HDPE water supply pipe, the heat of the end face of the HDPE water supply pipe can be absorbed. During the processing of the HDPE water supply pipe, the rapid dissipation of the end face heat helps to shorten the cooling time, thereby accelerating the production rhythm and improving the overall processing efficiency. At the same time, through the fitting and extrusion of the pressure regulating and heat conducting bladder and the traction hydraulic bladder, the heat absorbed by the liquid inside the traction hydraulic bladder can be absorbed, thereby further improving the heat dissipation effect of the traction hydraulic bladder and ensuring the effect of the traction hydraulic bladder absorbing the heat of the end face of the HDPE water supply pipe.

[0020] 3. The traction hydraulic bladder provided by the present invention can fit with the HDPE water supply pipe to be towed, so as to clamp and tow the HDPE water supply pipe through the traction hydraulic bladders symmetrically arranged up and down. The traction hydraulic bladders symmetrically arranged up and down can uniformly apply clamping force to the HDPE water supply pipe, avoiding pipe deformation or damage caused by uneven clamping force. The stable clamping force can also ensure the stability and consistency of the pipe during the processing, thereby improving the processing accuracy and product quality.

[0021] 4. The present invention can squeeze the traction hydraulic bag through the expansion of the pressure-regulating temperature-conducting bag, so that the amount of liquid stored in the upper and lower areas of the traction hydraulic bag can be different. By increasing the liquid in the pressure-regulating temperature-conducting bag, the liquid on the side of the traction hydraulic bag facing the inside of the pressure-regulating temperature-conducting bag can be squeezed, so that the liquid in the traction hydraulic bag facing the inside of the HDPE water supply pipe is increased. In this way, the clamping force of the traction hydraulic bag on the HDPE water supply pipe can be adjusted. By accurately controlling the amount of liquid in the pressure-regulating temperature-conducting bag, the clamping force of the traction hydraulic bag can be fine-tuned. This fine adjustment capability helps to improve the processing accuracy of the HDPE water supply pipe and ensure that the size, shape and other parameters of the pipeline meet the design requirements.

[0022] 5. In the present invention, when the toothed belt drives the limiting block to rotate, the limiting block can drive the corresponding adjusting block to rotate, so that the cooling water pipe itself can rotate in the assembly groove, which can further increase the spraying range of the cooling water pipe, thereby achieving a better cooling effect on the pulled HDPE water supply pipe.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] The present invention provides a technical solution:

[0035] Please refer to Figures 1 to 6 , a processing device for HDPE water supply pipes, including a bearing base 1. A clamping drive assembly 2 is arranged on the upper end surface of the bearing base 1. The clamping drive assembly 2 includes support guide posts 201 fixedly installed at the four corners of the upper end surface of the bearing base 1. A guide sliding sleeve 208 is slidably sleeved outside the support guide post 201. A bearing cross frame 207 is fixedly installed between the outer parts of two adjacent front and rear guide sliding sleeves 208. The clamping drive assembly 2 further includes a bearing top cover 202 fixedly installed between the tops of multiple support guide posts 201. A servo motor 203 is fixedly installed on the left side of the upper end surface of the bearing top cover 202. The output end of the servo motor 203 penetrates through the bearing top cover 202 and is fixedly connected with a bi-directional lead screw 204. The bottom end of the bi-directional lead screw 204 is rotatably connected with the bearing base 1; a nut 205 is threadedly connected to the outer wall of the bi-directional lead screw 204. A bearing sleeve 206 is fixedly installed outside the nut 205. The bearing sleeve 206 is fixedly connected with the bearing cross frame 207. A support cross plate 209 is fixedly installed between two adjacent left and right bearing cross frames 207. A traction drive assembly 3 is arranged inside and outside the bearing cross frame 207;

[0036] The traction drive assembly 3 includes a drive shaft 302 rotatably mounted at the front of the left and right adjacent two bearing cross frames 207. A driven shaft 307 is rotatably mounted at the rear between the left and right adjacent two bearing cross frames 207. Drive gears 303 are fixedly mounted on the outer walls of the driven shaft 307 and the drive shaft 302. A toothed belt 304 is meshed and connected between the front and rear adjacent two drive gears 303. A traction hydraulic bladder 306 is fixedly mounted between the left and right adjacent two toothed belts 304. The traction drive assembly 3 further includes a motor 301 fixedly mounted at the left top end of the left bearing cross frame 207. The output end of the motor 301 penetrates the bearing cross frame 207 and is fixedly connected to the drive shaft 302. A limiting block 305 is fixedly mounted on the outer side of the toothed belt 304, and the number of the limiting blocks 305 is set to be multiple.

[0037] By adopting the above technical solution, during use, the equipment can be moved to a suitable position through the casters installed at the bottom end of the bearing base 1. At this time, the approximate distance between the two traction drive assemblies 3 is adjusted according to the processing dimensions of the HDPE water supply pipe. When adjusting, the servo motor 203 is started. The operation of the servo motor 203 can drive the bidirectional lead screw 204 to rotate. The rotation of the bidirectional lead screw 204 can drive the nut 205 connected by threads to move up and down. The nut 205 moving up and down can drive the fixedly connected bearing sleeve 206 and the bearing cross frame 207 to move up and down. The left and right bearing cross frames 207 are connected by a supporting cross plate 209. The bearing cross frame 207 arranged in this way can slide up and down on the support guide post 201 through the guiding sliding sleeve 208. The two traction drive assemblies 3 are arranged on the bearing cross frame 207. Thus, the position between the two traction drive assemblies 3 can be adjusted by the two bearing cross frames 207 moving closer to or away from each other. In this way, the position between the two traction drive assemblies 3 can be adjusted within a large range, facilitating the distance between the traction drive assemblies 3 to adapt to the dimensional requirements of the HDPE water supply pipe; the adjustability of the bearing cross frame 207 enables the equipment to process HDPE water supply pipes with different diameters and lengths, increasing the applicable range and flexibility of the equipment. It can adapt to different specifications of pipes without replacing the equipment or components, reducing the production cost and time cost; the position between the traction drive assemblies 3 can be quickly adjusted according to the pipe size, reducing the adjustment time and waiting time, and improving the production efficiency; the adjustability of the bearing cross frame 207 can also help the equipment better adapt to other equipment and process requirements on the production line, realizing the overall optimization of the production line.

[0038] When performing the processing and traction of HDPE water supply pipes, start the motor 301. The operation of the motor 301 can drive the drive shaft 302 to rotate. Drive gears 303 are fixed on the outer walls of both the drive shaft 302 and the driven shaft 307. In this way, the toothed belt 304 can be driven to rotate through the drive gears 303. The rotation of the toothed belt 304 can drive the traction hydraulic bladder 306 thereon to rotate synchronously. The provided traction hydraulic bladder 306 can be mutually attached to the HDPE water supply pipe to be tractioned. Thus, the HDPE water supply pipe is clamped and tractioned by the traction hydraulic bladders 306 symmetrically arranged up and down. It should be noted here that the clamping traction force generated at the end face of the traction hydraulic bladder 306 and the end face of the HDPE water supply pipe is greater than the resistance suffered by the extruded HDPE water supply pipe when continuously pulled out from the mold. The traction hydraulic bladders 306 symmetrically arranged up and down can uniformly apply a clamping force to the HDPE water supply pipe, avoiding pipe deformation or damage caused by uneven clamping force. The clamping by the traction hydraulic bladder 306 can also ensure the stability and consistency of the pipe during the processing, thereby improving the processing accuracy and product quality; the traction hydraulic bladder 306 realizes the traction of the pipe through the hydraulic principle, has efficient and stable traction force. The symmetrical arrangement up and down can ensure the uniform distribution of the traction force, enabling the pipe to move forward smoothly during the traction process, reducing the pipe shaking or deviation caused by uneven traction force. By ensuring that the device has sufficient traction force to meet the production and processing requirements of HDPE water supply pipes, the processing quality of HDPE water supply pipes is guaranteed.

[0039] Specifically, as Figures 1 to 3 shown, a pressure regulating and temperature guiding component 4 is arranged on the right side of the upper end face of the bearing base 1. The pressure regulating and temperature guiding component 4 includes a hydraulic pump 401 fixedly installed on the right side of the upper end face of the bearing base 1, and the output end of the hydraulic pump 401 is fixedly communicated with a hydraulic conduit 402; the pressure regulating and temperature guiding component 4 also includes a pressure regulating and temperature guiding bladder 403 respectively fixed at the middle positions of the lower end face of the bearing top cover 202 and the upper end face of the bearing base 1. A limiting ring plate 404 is attached to the outside of the pressure regulating and temperature guiding bladder 403, and the limiting ring plate 404 is respectively fixed at the surrounding positions of the lower end face of the bearing top cover 202 and the upper end face of the bearing base 1.

[0040] By adopting the above technical solution, during use, the hydraulic pump 401 can be externally connected to a hydraulic pipe. When the hydraulic pump 401 is started, it can work to extract liquid and pump the liquid into the hydraulic conduit 402. Through the hydraulic conduit 402, the liquid can be pumped into the upper and lower pressure-regulating and temperature-guiding bladders 403. When the internal pressure of the pressure-regulating and temperature-guiding bladder 403 increases, the pressure-regulating and temperature-guiding bladder 403 itself will expand. The set limiting ring plate 404 can limit the periphery of the pressure-regulating and temperature-guiding bladder 403. The set bearing top cover 202 can bear the limiting ring plate 404 at the top and the pressure-regulating and temperature-guiding bladder 403. It should be noted that the lengths of the left and right sides and the front and back sides of the limiting ring plate 404 are different. The end faces of the left and right sides of the limiting ring plate 404 are in mutual contact with the end face of the toothed belt 304, so as to prevent the corresponding sides of the traction hydraulic bladder 306 and the pressure-regulating and temperature-guiding bladder 403 from expanding to the left and right sides when being squeezed, so that the expansion direction of the pressure-regulating and temperature-guiding bladder 403 faces the traction hydraulic bladder 306. Through the expansion of the pressure-regulating and temperature-guiding bladder 403, the traction hydraulic bladder 306 can be squeezed, and then the amounts of liquid stored in the upper and lower regions inside the traction hydraulic bladder 306 can be made different. By the increase of the liquid inside the pressure-regulating and temperature-guiding bladder 403, the liquid on the side of the traction hydraulic bladder 306 facing the inside of the pressure-regulating and temperature-guiding bladder 403 can be squeezed, so that the liquid in the traction hydraulic bladder 306 facing the inside of the HDPE water supply pipe increases. In this way, the clamping force of the traction hydraulic bladder 306 on the HDPE water supply pipe can be adjusted. By precisely controlling the amount of liquid inside the pressure-regulating and temperature-guiding bladder 403, the fine adjustment of the clamping force of the traction hydraulic bladder 306 can be realized. This fine adjustment ability helps to improve the processing accuracy of the HDPE water supply pipe and ensure that parameters such as the size and shape of the pipe meet the design requirements; during the processing, a stable clamping force is crucial for ensuring the quality of the pipe. Through the adjustment of the pressure-regulating and temperature-guiding bladder 403, it can be ensured that the traction hydraulic bladder 306 applies a constant clamping force to the pipe, avoiding problems such as pipe deformation and dislocation caused by insufficient or excessive clamping force.

[0041] Meanwhile, the traction hydraulic bladder 306 is filled with liquid inside. By clamping and adhering to the HDPE water supply pipe through the traction hydraulic bladder 306, the heat at the end face of the HDPE water supply pipe can be absorbed. During the processing of the HDPE water supply pipe, the rapid dissipation of the end face heat helps to shorten the cooling time, thereby accelerating the production rhythm and improving the overall processing efficiency. The traction hydraulic bladder 306 absorbs and conducts heat through the liquid filled inside, which can effectively help the end face of the HDPE water supply pipe cool down quickly. The processing quality of the HDPE water supply pipe largely depends on the flatness and heat fusion effect of its end face. The clamping and adhering of the traction hydraulic bladder 306 can not only ensure the stability of the HDPE water supply pipe during processing, but also avoid deformation or cracks at the end face due to overheating by absorbing heat, thus ensuring the processing quality. At the same time, through the fitting and extrusion of the pressure regulating and temperature guiding bladder 403 and the traction hydraulic bladder 306, the heat absorbed by the liquid inside the traction hydraulic bladder 306 can be absorbed, thereby further improving the heat dissipation effect of the traction hydraulic bladder 306 and ensuring the heat absorption effect of the traction hydraulic bladder 306 on the end face of the HDPE water supply pipe.

[0042] When the pressure regulating and temperature guiding bladder 403 expands to squeeze the traction hydraulic bladder 306, the liquid inside the traction hydraulic bladder 306 facing the inside of the HDPE water supply pipe increases. In this way, the side of the traction hydraulic bladder 306 facing the HDPE water supply pipe can expand. Through the expansion of the traction hydraulic bladder 306 facing the HDPE water supply pipe, the clamping area of the traction hydraulic bladder 306 on the HDPE water supply pipe can be increased. At the same time, when the side of the traction hydraulic bladder 306 facing the HDPE water supply pipe expands, a plurality of limiting blocks 305 arranged in cooperation can play a limiting role on the traction hydraulic bladder 306, so that the expansion surface of the traction hydraulic bladder 306 fully adheres to the clamping end face of the HDPE water supply pipe, thereby being able to better wrap and clamp the HDPE water supply pipe, further improving the clamping and traction effect. The adhesion surface of the traction hydraulic bladder 306 for clamping the pipe increases to ensure that the pipe does not slip off stably during traction, thereby improving the processing quality of the HDPE water supply pipe.

[0043] Specifically, such as Figure 1 、 Figures 3 to 7As shown in the figure, a cooling and shaping component 5 is arranged at the left rear of the upper end surface of the bearing base 1. The cooling and shaping component 5 includes a water pump 501 fixed at the left rear end of the upper end surface of the bearing base 1, and the output end of the water pump 501 is fixedly communicated with an infusion water pipe 502; the cooling and shaping component 5 further includes an assembly groove 503 opened at the rear end of the bearing cross frame 207. An assembly bearing 507 is arranged inside the assembly groove 503, and the outer ring of the assembly bearing 507 is fixedly installed with the outer wall of the assembly groove 503. A cooling water pipe 504 is fixedly installed between the inner rings of the two assembly bearings 507, and the cooling water pipe 504 is rotatably connected with the output end of the infusion water pipe 502; torsion springs 506 are fixedly installed at both ends of the cooling water pipe 504 located in the assembly groove 503, and an adjustment block 505 is fixedly installed on the right side of the outer wall of the cooling water pipe 504; the number of the cooling water pipes 504 is two, second spray holes 509 are opened on the adjacent end faces of the two cooling water pipes 504, and first spray holes 508 are opened on the end faces of the cooling water pipes 504 close to the traction hydraulic bladder 306. A water collection tank 510 corresponding to the cooling water pipe 504 is fixedly installed at the rear end of the bearing base 1.

[0044] By adopting the above technical solution, when in use, the water pump 501 can be connected to an external water pipe, and the water pump 501 can be started. The water pump 501 can draw cold water when it is working. The cold water can be respectively transported to the two cooling water pipes 504 through the infusion water pipe 502. The cold water can be sprayed onto the HDPE water supply pipe to be clamped through the second spray hole 509 opened on the end surface of the cooling water pipe 504. The water spray cooling can quickly take away the heat generated by the HDPE water supply pipe during the processing, which helps to speed up the cooling speed and shorten the production cycle. By reducing the temperature of the pipe, the problem of material deformation and dimensional change caused by high temperature during the processing and traction process can be reduced. The yield and consistency of the product are improved; at the same time, the first spray hole 508 corresponding to the traction hydraulic bag 306 opened on the end face of the cooling water pipe 504 can spray cold water on the traction hydraulic bag 306, thereby further reducing the heat absorbed by the liquid inside the traction hydraulic bag 306 on the HDPE water supply pipe, ensuring the traction hydraulic bag 306 The clamping stability effect and cooling and heat absorption effect of the HDPE water supply pipe, the upper end of the water collecting tank 510 is opened, and the opening corresponds to the spraying range of the first spray hole 508 and the second spray hole 509, so that the cold water generated by the first spray hole 508 and the second spray hole 509 when spraying can be collected. The cooling water pipe 504 is rotatably installed in the assembly groove 503 at the rear end of the supporting cross frame 207 through the assembly bearing 507, so that when the toothed belt 304 drives the limiting block 305 to rotate, the limiting block 305 can drive the corresponding adjusting block 505 to rotate, so that the cooling water pipe 504 itself can rotate in the assembly groove 503, which can further increase the spraying range of the cooling water pipe 504, thereby achieving a better cooling effect on the pulled HDPE water supply pipe. When the limiting block 305 no longer drives the corresponding adjusting block 505 to rotate, the cooling water pipe 504 will return to the initial position under the action of the elastic force recovery of the torsion spring 506, so that the cooling water pipe 504 can be repeatedly rotated by the rotation cooperation of the limiting block 305, the adjusting block 505 and the torsion spring 506, thereby further improving the cooling effect of the cooling water pipe 504.

[0045] Working principle: During use, the casters installed at the bottom end of the bearing base 1 can move the device to a suitable position. At this time, the approximate distance between the two traction drive components 3 is adjusted according to the processing dimensions of the HDPE water supply pipe. When adjusting, the servo motor 203 is started. The operation of the servo motor 203 can drive the bidirectional lead screw 204 to rotate. The rotation of the bidirectional lead screw 204 can drive the nut 205 connected by threads to move up and down. The nut 205 moving up and down can drive the fixedly connected bearing sleeve 206 and the bearing cross frame 207 to move up and down. The bearing cross frames 207 on the left and right sides are connected by a supporting cross plate 209. The bearing cross frame 207 arranged in this way can slide up and down on the support guide post 201 through the guiding sliding sleeve 208. The two traction drive components 3 are arranged on the bearing cross frame 207. Thus, the position between the two traction drive components 3 can be adjusted by the two bearing cross frames 207 moving closer to or separating from each other. In this way, the position between the two traction drive components 3 can be adjusted within a large range, facilitating the distance between the traction drive components 3 to adapt to the size requirements of the HDPE water supply pipe. When performing the traction for the processing of the HDPE water supply pipe, the motor 301 is started. The operation of the motor 301 can drive the drive shaft 302 to rotate. Driving gears 303 are fixedly installed on the outer walls of the drive shaft 302 and the driven shaft 307. In this way, the toothed belt 304 can be driven to rotate through the driving gears 303. The rotation of the toothed belt 304 can drive the traction hydraulic bladder 306 thereon to rotate synchronously. The arranged traction hydraulic bladder 306 can be mutually attached to the HDPE water supply pipe to be tractioned. Thus, the HDPE water supply pipe is clamped and tractioned by the traction hydraulic bladders 306 arranged symmetrically up and down.

[0046] During use, the hydraulic pump 401 can be externally connected to a hydraulic pipe. When the hydraulic pump 401 is started, it can pump liquid and pump the liquid into the hydraulic conduit 402. Through the hydraulic conduit 402, the liquid can be pumped into the upper and lower pressure-regulating and temperature-guiding bladders 403. When the internal pressure of the pressure-regulating and temperature-guiding bladder 403 increases, the pressure-regulating and temperature-guiding bladder 403 itself will expand. The set limiting ring plate 404 can limit the periphery of the pressure-regulating and temperature-guiding bladder 403. The set bearing top cover 202 can bear the limiting ring plate 404 at the top and the pressure-regulating and temperature-guiding bladder 403. It should be noted that the lengths of the left and right sides and the front and back sides of the limiting ring plate 404 are different. The end faces of the left and right sides of the limiting ring plate 404 are in contact with the end face of the toothed belt 304, so as to prevent the corresponding sides of the traction hydraulic bladder 306 and the pressure-regulating and temperature-guiding bladder 403 from expanding to the left and right when being squeezed, so that the expansion direction of the pressure-regulating and temperature-guiding bladder 403 faces the traction hydraulic bladder 306. Through the expansion of the pressure-regulating and temperature-guiding bladder 403, the traction hydraulic bladder 306 can be squeezed, and then the amounts of liquid stored in the upper and lower regions inside the traction hydraulic bladder 306 can be made different. Through the increase of the liquid inside the pressure-regulating and temperature-guiding bladder 403, the liquid on the side of the traction hydraulic bladder 306 facing the inside of the pressure-regulating and temperature-guiding bladder 403 can be squeezed, so that the liquid facing the inside of the HDPE water supply pipe in the traction hydraulic bladder 306 increases. In this way, the clamping force of the traction hydraulic bladder 306 on the HDPE water supply pipe can be adjusted. At the same time, the traction hydraulic bladder 306 is filled with liquid. Through the fitting and clamping of the traction hydraulic bladder 306 on the HDPE water supply pipe, the heat on the end face of the HDPE water supply pipe can be absorbed. Through the fitting and extrusion of the pressure-regulating and temperature-guiding bladder 403 and the traction hydraulic bladder 306, the heat absorbed by the liquid inside the traction hydraulic bladder 306 can be absorbed, thereby further improving the heat dissipation effect of the traction hydraulic bladder 306 and ensuring the effect of the traction hydraulic bladder 306 absorbing the heat on the end face of the HDPE water supply pipe; when the pressure-regulating and temperature-guiding bladder 403 expands to squeeze the traction hydraulic bladder 306, the liquid facing the inside of the HDPE water supply pipe in the traction hydraulic bladder 306 increases, so that one side of the traction hydraulic bladder 306 facing the HDPE water supply pipe expands. Through the expansion of the traction hydraulic bladder 306 facing the HDPE water supply pipe, the clamping area of the traction hydraulic bladder 306 on the HDPE water supply pipe can be increased. At the same time, when the traction hydraulic bladder 306 expands on the side facing the HDPE water supply pipe, the cooperation of the set multiple limiting blocks 305 can limit the traction hydraulic bladder 306, so that the expansion surface of the traction hydraulic bladder 306 fully fits on the clamping end face of the HDPE water supply pipe, so as to better wrap and clamp the HDPE water supply pipe and further improve the clamping and traction effect.

[0047] When in use, the water pump 501 can be connected to an external water pipe, and the water pump 501 is started. The water pump 501 can draw cold water when it works. The cold water can be transported to the two cooling water pipes 504 respectively through the infusion water pipe 502, and the cold water can be sprayed onto the HDPE water supply pipe to be clamped through the second spray hole 509 opened on the end surface of the cooling water pipe 504; at the same time, the cold water can be sprayed on the traction hydraulic bag 306 through the first spray hole 508 opened on the end surface of the cooling water pipe 504 and corresponding to the traction hydraulic bag 306, thereby further reducing the heat absorbed by the internal liquid of the traction hydraulic bag 306 on the HDPE water supply pipe, ensuring the clamping stability effect and cooling and heat absorption effect of the traction hydraulic bag 306 on the HDPE water supply pipe, and the upper end of the water collecting tank 510 is opened, and the opening corresponds to the spraying range of the first spray hole 508 and the second spray hole 509, so that the first spray hole 508 and the second spray hole 509 can be collected. The cold water generated when the hole 509 is sprayed is used for the cooling water pipe 504 to be rotatably installed in the assembly groove 503 at the rear end of the supporting cross frame 207 through the assembly bearing 507. Therefore, when the toothed belt 304 drives the limiting block 305 to rotate, the limiting block 305 can drive the corresponding adjusting block 505 to rotate, so that the cooling water pipe 504 itself can rotate in the assembly groove 503, which can further increase the spraying range of the cooling water pipe 504, thereby achieving a better cooling effect on the pulled HDPE water supply pipe. When the limiting block 305 no longer drives the corresponding adjusting block 505 to rotate, the cooling water pipe 504 will return to the initial position under the action of the elastic force recovery of the torsion spring 506, thereby realizing the repeated rotation of the cooling water pipe 504 under the rotation cooperation of the limiting block 305, the adjusting block 505 and the torsion spring 506, thereby further improving the cooling effect of the cooling water pipe 504.
