Description

Technical Field

[0001] This utility model relates to the field of pipe processing equipment technology, and in particular to a rapid cooling and shaping device for thermoplastic elastomer extruded pipes. Background Technology

[0002] Thermoplastic elastomers are materials that combine the processing characteristics of thermoplastics with the properties of vulcanized rubber. At room temperature, they possess the elasticity of rubber, undergoing elastic deformation and returning to their original shape like rubber. At high temperatures, they can melt and flow like thermoplastics. They can be molded using thermoplastic processing methods such as injection molding, extrusion, and blow molding. Due to their excellent wear resistance, elasticity, and weather resistance, they are widely used in the pipe manufacturing industry. In the production process of thermoplastic elastomer extruded pipes, the pipes are at a high temperature after extrusion and require rapid cooling and shaping to ensure the dimensional accuracy and surface quality of the pipes.

[0003] Although existing cooling and shaping devices are widely used in processing, they still have some shortcomings and limitations. For example, existing cooling and shaping devices have low cooling efficiency and uneven cooling, which makes the pipes prone to deformation and rough surfaces during processing, affecting product quality and production efficiency.

[0004] Therefore, it is necessary to design a rapid cooling and shaping device for thermoplastic elastomer extruded pipes. Utility Model Content

[0005] In order to overcome the shortcomings of existing cooling and shaping devices, such as low cooling efficiency and uneven cooling, which leads to defects such as deformation and rough surface of the pipe during processing, affecting product quality and production efficiency, this utility model provides a rapid cooling and shaping device for thermoplastic elastomer extruded pipes.

[0006] Technical Solution: A rapid cooling and shaping device for thermoplastic elastomer extruded pipes, comprising a base plate, a spray frame, a servo motor, a first transmission roller, a second transmission roller, a transmission assembly, a spur gear, a water tank, a water pump, connecting pipes, a spray ring, and connecting pipes. A water tank is fixedly connected to the top right side of the base plate. Multiple connecting pipes are fixedly connected to the top of the water tank. A spray frame is fixedly connected between the tops of the multiple connecting pipes. A servo motor is installed on the front side of the spray frame. Multiple first transmission rollers are rotatably connected between the front and rear sides of the lower end inside the spray frame. The output shaft of the servo motor is connected to the rightmost first transmission roller. The spray frame is connected to the moving rollers. Multiple second drive rollers are rotatably connected between the front and rear sides of the upper part of the spray frame. Multiple first drive rollers are symmetrically distributed with multiple second drive rollers. Both the first and second drive rollers pass through the spray frame. A transmission component is provided between the front sides of every two adjacent first drive rollers. A spur gear is fixedly connected to the rear side of each first and second drive roller. Every two symmetrically distributed spur gears mesh with each other. A connecting pipe is fixedly connected to the front side of the water tank. A water pump is installed on the connecting pipe. Multiple spray rings are fixedly connected to the connecting pipe.

[0007] In one embodiment, a soaking frame is also included, which is fixedly connected to the top left side of the base plate.

[0008] In one embodiment, the device also includes a placement rack and an electric push rod, with the electric push rod mounted on the front side of the base plate and the placement rack connected to the telescopic rod of the electric push rod.

[0009] In one embodiment, a limiting shell is also included, with the limiting shell fixedly connected to the rear side of the soaking frame, and the placement rack slidably connected to the limiting shell.

[0010] In one embodiment, a filter screen is also included, and the connecting pipes are all fixedly connected to the filter screens.

[0011] In one embodiment, the water tank also includes a cooler, a cooling pipe, and a protective shell. The cooler is installed at the rear of the water tank, and the cooling pipe is fixedly connected to the top of the water tank. The cooler is connected to the cooling pipe, and the protective shell is fixedly connected to the top of the water tank. The cooling pipe is located inside the protective shell, and its rear side penetrates the protective shell and is fixedly connected to it.

[0012] Beneficial effects: 1. By starting the water pump, the coolant in the water tank is drawn out and transported to the spray ring through the connecting pipe. The spray ring surrounds the pipe and sprays the coolant evenly on the surface of the pipe, absorbing the heat of the pipe and rapidly reducing the surface temperature of the pipe. This solves the problems of low cooling efficiency and uneven cooling of existing cooling and shaping devices, which lead to defects such as deformation and rough surface of the pipe during processing, affecting product quality and production efficiency.

[0013] 2. This utility model, by setting up a cooler, a cooling pipe and a protective shell, cools the cooling pipe through a cooling medium when the cooler is started. The cooling pipe transfers the cooling energy to the connecting pipe, keeping the connecting pipe at a low temperature. During the spray cooling process, the coolant flowing over the surface of the pipe will be cooled by gravity and then flow back into the water tank after being filtered by the filter screen to remove impurities. This achieves the circulation and cooling of the coolant and ensures a continuous supply of coolant. Attached Figure Description

Detailed Implementation

[0022] Example: A rapid cooling and shaping device for thermoplastic elastomer extruded pipes, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and 7As shown, the system includes a base plate 1, a spray frame 6, a servo motor 7, a first transmission roller 8, a second transmission roller 9, a transmission assembly 10, a spur gear 11, a water tank 12, a water pump 13, a connecting pipe 14, a spray ring 15, and a connecting pipe 16. A water tank 12 is welded to the top right side of the base plate 1. Four connecting pipes 16 are welded to the top of the water tank 12. A spray frame 6 is welded between the tops of the four connecting pipes 16. A servo motor 7 is installed on the front side of the spray frame 6. Five first transmission rollers 8 are rotatably connected between the front and rear sides of the lower end inside the spray frame 6. The output shaft of the servo motor 7 is connected to the rightmost first transmission roller 8. A connecting pipe 14 is rotatably connected between the front and rear sides of the upper end inside the spray frame 6. Five second drive rollers 9 and five first drive rollers 8 are symmetrically distributed vertically with the five second drive rollers 9. The first drive rollers 8 and the second drive rollers 9 both pass through the spray frame 6. A transmission assembly 10 is provided between the front sides of every two adjacent first drive rollers 8. A spur gear 11 is welded to the rear side of each first drive roller 8 and each second drive roller 9. Every two symmetrically distributed spur gears 11 mesh with each other. A connecting pipe 14 is welded to the front side of the water tank 12. A water pump 13 is installed on the connecting pipe 14. Four spray rings 15 are welded to the connecting pipe 14, which can reduce the surface temperature of the pipe over a large area and quickly, laying the foundation for subsequent cooling steps.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it also includes a soaking frame 2, a placement rack 3, a limiting shell 4, and an electric push rod 5. The soaking frame 2 is welded to the top left side of the base plate 1. Soaking and cooling can continuously cool the pipe in a relatively stable low-temperature environment, which helps to stabilize the internal structure of the pipe and further improves the cooling and shaping effect. An electric push rod 5 is installed on the front side of the base plate 1. The placement rack 3 is connected to the telescopic rod of the electric push rod 5. The limiting shell 4 is welded to the rear side of the soaking frame 2. The placement rack 3 is slidably connected to the limiting shell 4, which can limit and guide the movement of the placement rack 3, ensuring that the placement rack 3 moves smoothly and preventing deviation.

[0024] like Figure 7 As shown, it also includes a filter screen 17. The inside of the connecting pipe 16 is welded with a filter screen 17 to filter impurities in the coolant, prevent impurities from clogging the connecting pipe 16, ensure the normal circulation and spraying of the coolant, and ensure the stable operation of the cooling system.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7As shown, it also includes a cooler 18, a cooling pipe 19 and a protective shell 20. The cooler 18 is installed on the rear side of the water tank 12, and the cooling pipe 19 is welded to the top of the water tank 12. The cooler 18 is connected to the cooling pipe 19. The protective shell 20 is welded to the top of the water tank 12. The cooling pipe 19 is located inside the protective shell 20, and its rear side penetrates the protective shell 20 and is welded to it.

[0026] When rapid cooling and shaping of thermoplastic elastomer extruded pipes is required, first pour coolant into the soaking frame 2, then insert the thermoplastic elastomer extruded pipe into the spray frame 6 from the right side. Start the servo motor 7, water pump 13, and cooler 18. The output shaft of the servo motor 7 rotates, driving the first transmission roller 8 connected to it to rotate. The rotation of the first transmission roller 8 drives the spur gear 11 on it to rotate, thereby driving the second transmission roller 9 on it to rotate in the opposite direction through the meshing spur gear 11. At the same time, the rotation of the rightmost first transmission roller 8 is driven by the transmission assembly 10. It will also drive other first drive rollers 8 to rotate. Multiple first drive rollers 8 and second drive rollers 9 together form a transmission system, clamping the pipe between the first drive rollers 8 and the second drive rollers 9. Through the friction generated by the rotation, the pipe is driven from the right end to the left end of the spray frame 6. During the transportation process, the water pump 13 starts to extract the coolant from the water tank 12. The coolant is transported to the spray ring 15 through the connecting pipe 14. The spray ring 15 surrounds the pipe and can spray the coolant evenly on the surface of the pipe, absorb the heat of the pipe, and make the surface temperature of the pipe drop rapidly for preliminary cooling treatment.

[0027] When the cooler 18 is started, it cools the cooling pipe 19 through the cooling medium. The cooling pipe 19 transfers the cooling capacity to the connecting pipe 16, keeping the connecting pipe 16 at a low temperature. During the spray cooling process, the coolant flowing over the surface of the pipe will be cooled by gravity and pass through the connecting pipe 16. After the filter screen 17 filters impurities, it flows back into the water tank 12, realizing the circulation and cooling of the coolant. After the cooling is completed, the extrusion pipe is sent out from the left end of the spray frame 6 and falls into the immersion frame 2. The pipe is immersed in the coolant, and the heat inside is further dissipated into the coolant through heat transfer, achieving more thorough cooling.

[0028] After the pipe has cooled and set, the servo motor 7, water pump 13, and cooler 18 are turned off. The electric push rod 5 is started, and the extension rod of the electric push rod 5 extends, driving the placement frame 3 to move upward on the limiting shell 4 to catch the cooled and set pipe. After the pipe is no longer in contact with the coolant, the electric push rod 5 is turned off, and the cooled and set pipe can be taken out for subsequent processing. Finally, the extension rod of the electric push rod 5 is controlled to retract so that the placement frame 3 returns to its original position. This completes the process of rapid cooling and setting of thermoplastic elastomer extruded pipe by this device.
