Description

Technical Field

[0001] This utility model relates to the field of pipe rounding technology, specifically to a rounding device for processing engineering plastic pipes. Background Technology

[0002] Most plastic pipes are produced by extrusion. During the extrusion process, the freshly extruded plastic pipes are at high temperatures and are prone to deformation. Deformed plastic pipes need to be rounded, requiring the use of pipe rounding equipment.

[0003] An existing plastic pipe straightening device, such as Chinese patent application number CN215703983U, includes a base, on which a straightening cylinder is rotatably mounted via a support seat. The straightening cylinder is connected to a drive device for rotating it. Both ends of the straightening cylinder have openings for the pipe to pass through. Inside the straightening cylinder, rollers are installed via an adjustment mechanism. The rollers are arranged in a circular array around the central axis of the straightening cylinder, and the axial direction of the rollers is parallel to the central axis of the straightening cylinder. The adjustment mechanism is used to adjust the axial distance between the rollers and the straightening cylinder. The side wall of the straightening cylinder has fan blades arranged in a circular array along its circumference, and air outlets are located between adjacent fan blades. Although the existing pipe straightening device can achieve a good rounding effect, it cannot achieve active loading and unloading. After the rounding is completed, manual operation is required, resulting in low overall rounding efficiency.

[0004] Therefore, we propose a rounding device for processing engineering plastic pipes to solve the problems mentioned above. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 This utility model provides a technical solution: a rounding device for processing engineering plastic pipes, including a support platform 1, a first positioning frame 2 fixed to the upper left side of the support platform 1, first positioning rollers 3 installed on both sides of the first positioning frame 2, a transmission roller 4 installed at the lower end of the first positioning frame 2, a positioning frame 9 set at the upper end of the first positioning frame 2, and a second positioning roller 10 connected to the lower end of the positioning frame 9; the first positioning rollers 3 are symmetrically distributed on both sides of the first positioning frame 2, and both the first positioning rollers 3 and the transmission rollers 4 are rotatably connected to the inner wall of the first positioning frame 2; a transmission motor 6 is fixed to the upper end of the support platform 1, and a second pulley 7 is connected to the front axle end of the transmission motor 6; a first pulley 5 is connected to the front end of the transmission roller 4, and the first pulley 5 and the second pulley... A transmission belt 8 connects the 7 components; a positioning tube 11 is fixed to the inner wall of the upper end of the first positioning frame 2, and the upper end of the positioning frame 9 is slidably connected to the positioning tube 11. A threaded rod 12 is rotatably connected to the upper end of the first positioning frame 2, and the lower end of the threaded rod 12 is threadedly connected to the upper end of the positioning frame 9. Through the cooperation of the first positioning frame 2, the first positioning roller 3, the transmission roller 4, and the second positioning roller 10, the pipe can be limited and actively fed. The two sets of first positioning rollers 3 limit the two sides of the pipe, while the transmission roller 4 can support the lower end of the pipe and perform horizontal feeding transmission. The transmission motor 6 drives the second pulley 7 to rotate, and the second pulley 7 drives the first pulley 5 and the transmission roller 4 to rotate through the transmission belt 8, thereby realizing the feeding of the pipe. The transmission belt 8 is a synchronous belt with equally spaced toothed grooves on its inner surface. The outer surfaces of the first pulley 5 and the second pulley 7 are provided with convex teeth that are compatible with the transmission belt 8 to maintain stable transmission.

[0033] During the pipe feeding process, in order to maintain the transmission stability between the pipe and the transmission roller 4, the transmission roller 4 and the pipe need to maintain a large friction force. The second positioning roller 10 can be adjusted to press down on it. The rotating threaded rod 12 can drive the positioning frame 9 and the second positioning roller 10 to move downward and contact the upper end face of the pipe to achieve pressing and limiting. When the positioning frame 9 is raised and lowered, the positioning tube 11 can be used to improve its activity stability.

[0034] A second positioning frame 13 is fixed to the upper end of the support platform 1. A heating tube 14 is fixed to the upper end of the second positioning frame 13, and an electric heating wire 15 is installed on the inner wall of the heating tube 14. A third positioning frame 26 is fixed to the upper right side of the support platform 1. A straightening tube 16 is rotatably connected to the upper end of the third positioning frame 26, and a straightening roller 17 is set inside the straightening tube 16. The straightening roller 17 is designed with an inclination and is arranged in a ring array around the center of the straightening tube 16. The straightening roller 17 is rotatably connected to the inner wall of the straightening tube 16. A straightening motor 19 is fixed to the upper end of the support platform 1, and a drive gear 20 is connected to the left shaft end of the straightening motor 19. The straightening tube 1... 6. An external transmission gear ring 18 is connected, and the lower end of the transmission gear ring 18 meshes with the drive gear 20. The heating tube 14 and the heating wire 15 are positioned by the second positioning frame 13. After the heating wire 15 is heated to a suitable temperature, it passes through the inside of the heating tube 14 during the tube feeding process to soften the tube, which is convenient for subsequent rounding treatment. The softened tube moves into the rounding tube 16 and is driven by the rounding motor 19 to rotate the drive gear 20. The drive gear 20 drives the transmission gear ring 18, the rounding tube 16 and the rounding roller 17 to rotate synchronously. The rounding treatment of the tube can be achieved during the rotation of multiple sets of rounding rollers 17.

[0035] A cooling structure is installed on the upper right side of the support platform 1 to cool the pipe after rounding. A cooling hood 21 is fixed to the upper right side of the support platform 1, and cooling fans 22 are fixed to the inner walls of the upper and lower ends of the cooling hood 21. Ventilation holes are opened on all four sides of the cooling hood 21. After rounding, the pipe needs to be cooled. The rounded pipe is transported into the cooling hood 21, and the airflow is driven by two sets of cooling fans 22 symmetrically arranged on the upper and lower sides of the cooling hood 21 to achieve cooling. The airflow direction of the two sets of cooling fans 22 is the same.

[0036] Please see Figure 7 and Figure 8This utility model provides another technical solution. The difference between this embodiment and embodiment one is that the cooling method of the pipe is different. This embodiment adopts a water-cooling cooling method: a cooling box 23 is fixed at the upper right side of the support platform 1, and through holes are opened in the middle of both sides of the cooling box 23. A cooling nozzle 24 is installed on the inner wall of the upper end of the cooling box 23. A liquid storage tank 25 is set at the bottom of the cooling box 23, and a collection hole is opened at the upper end of the liquid storage tank 25. When the pipe moves into the cooling box 23, liquid is supplied to the cooling nozzle 24 by an external liquid supply device, and the cooling nozzle 24 sprays the coolant into the cooling box 23 to cool the pipe. The sprayed coolant can flow into the liquid storage tank 25 through the collection hole opened at the upper end of the liquid storage tank 25 for collection, reducing resource waste.
