Description

Technical Field

[0001] This utility model relates to the technical field of PE pipe production, specifically a PE pipe production traction device. Background Technology

[0002] PE pipe production typically employs a continuous extrusion process. The extruder continuously extrudes molten polyethylene, which is then shaped through a sizing drum and a vacuum chamber. During this continuous production process, a traction device is required to pull the PE pipe forward at the front end to prevent blockage at the extruder.

[0003] For example, a PE pipe production traction device with authorization announcement number "CN222794362U" solves the problem that the threads on the surface of threaded pipes are easily worn when the existing PE pipe production traction device is used for a long time. The above-mentioned device places a part of the PE pipe inside the two rotating drums, which are concave. This allows the PE pipe to be transported stably when transporting PE pipes of different sizes, preventing the PE pipe from shaking back and forth during transportation and avoiding bending during traction. Considering that the existing PE pipe production traction device lacks flexibility due to its interconnected structure, the adjustment and adaptation process is time-consuming and laborious, and the PE pipe is prone to displacement or surface damage during traction. Utility Model Content

[0004] The purpose of this invention is to solve the problems of time-consuming and labor-intensive adjustment and adaptation processes in existing PE pipe production traction devices, and the easy occurrence of PE pipe deviation or surface damage during traction. Therefore, this invention proposes a PE pipe production traction device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PE pipe production traction device, comprising a mounting plate and a base, wherein the outer side of the base is fixedly connected to the mounting plate, the inner wall of the base is rotatably connected to a round rod, the outer wall of the round rod is fixedly connected to a silicone sleeve, and a limit mechanism is connected to the upper end of the base.

[0006] The addition of the silicone sleeve increases the friction between the silicone sleeve and the PE pipe, ensuring the stability of the traction.

[0007] Preferably, the limiting mechanism includes a mounting frame, which is threadedly connected to the base by bolts. The inner wall of the mounting frame is fixedly connected to the slide bar, the outer wall of the slide bar is slidably connected to the limiting bar, and the upper end of the limiting bar is threadedly connected to the mounting frame by bolts.

[0008] This limiting mechanism effectively positions the PE pipe, preventing it from shifting during traction. Preferably, the inner wall of the limiting strip is fixedly connected to the arc-shaped plate, and the upper end of the base is connected to a traction mechanism.

[0009] The curved plate design allows for better contact with the outer wall of the PE pipe, further enhancing the positioning effect while reducing damage to the pipe surface. The addition of a traction mechanism provides stable tension, ensuring the PE pipe maintains a uniform speed during production.

[0010] Preferably, the traction mechanism includes a fixed frame, the lower end of which is fixedly connected to the base, the inner wall of which is rotatably connected to the straight rod, and the outer wall of which is fixedly connected to the traction block.

[0011] The design of this traction mechanism aims to achieve stable traction of the PE pipe through the cooperation of the straight rod and the traction block.

[0012] Preferably, a motor is mounted on the outer wall of the fixing frame, and the output shaft of the motor is fixedly connected to the straight rod.

[0013] This motor setting provides a power source for the traction mechanism. The motor drives the straight rod to rotate, thereby driving the traction block to pull the PE pipe, ensuring the continuity and stability of the traction process.

[0014] Preferably, the inner wall of the mounting plate is machined with threaded holes.

[0015] The threaded hole design facilitates quick connection and fixation of the mounting plate to other equipment, improving the installation efficiency and flexibility of the entire device.

[0016] Preferably, the outer wall of the traction block is fixedly connected to the silicone roller.

[0017] The inclusion of the silicone roller further increases the friction between the roller and the PE pipe while preventing damage to the pipe surface, ensuring stability and safety during the traction process. Furthermore, the silicone material possesses excellent wear resistance and flexibility, maintaining good performance over extended use and extending the device's lifespan.

[0018] The PE pipe production traction device proposed in this utility model has the following advantages: through the cooperation of the sliding strip and the limiting strip, it can be flexibly adjusted to adapt to PE pipes of different sizes. At the same time, the arc plate further enhances the positioning effect and reduces wear on the pipe surface. In addition, the dual setting of silicone sleeve and silicone roller not only increases the friction but also avoids damage to the PE pipe surface, thereby improving the overall production stability. It has strong adaptability and practicality, and reduces the likelihood of PE pipes shifting or being damaged during the traction process. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings: Please see Figure 1-6 In this embodiment, A PE pipe production traction device includes a mounting plate 1 and a base 2. The outer side of the base 2 is fixedly connected to the mounting plate 1, the inner wall of the base 2 is rotatably connected to a round rod 3, the outer wall of the round rod 3 is fixedly connected to a silicone sleeve 4, and a limit mechanism 5 is connected to the upper end of the base 2.

[0022] The limiting mechanism 5 includes a mounting frame 501. By changing the limiting strip 503 on the mounting frame 501 and controlling its height, the lower end of the limiting strip 503 can achieve the limiting effect. The mounting frame 501 is threadedly connected to the base 2 by bolts. The inner wall of the mounting frame 501 is fixedly connected to the slide bar 502. The outer wall of the slide bar 502 is slidably connected to the limiting strip 503. The upper end of the limiting strip 503 is threadedly connected to the mounting frame 501 by bolts. The combination of slide bar 502 and limit bar 503 allows for flexible adjustment to accommodate PE pipes of different sizes. Meanwhile, the arc plate 6 further enhances the positioning effect and reduces wear on the pipe surface. In addition, the dual setting of silicone sleeve 4 and silicone roller 10 not only increases friction but also avoids damage to the PE pipe surface, thereby improving the overall production stability. It has strong adaptability and practicality, reducing the likelihood of PE pipes shifting or being damaged during traction.

[0023] The inner wall of the limiting strip 503 is fixedly connected to the arc plate 6. The upper end of the base 2 is connected to the traction mechanism 7. The traction mechanism 7 includes a fixed frame 701. The lower end of the fixed frame 701 is fixedly connected to the base 2. The inner wall of the fixed frame 701 is rotatably connected to the straight rod 702. The outer wall of the straight rod 702 is fixedly connected to the traction block 703.

[0024] A motor 8 is mounted on the outer wall of the fixed frame 701. The output shaft of the motor 8 is fixedly connected to the straight rod 702. A threaded hole 9 is machined on the inner wall of the mounting plate 1. The outer wall of the traction block 703 is fixedly connected to the silicone roller 10.

[0025] Working principle: During assembly, the base 2 is first fixedly connected to the mounting plate 1 to ensure its stability. Then, the round rod 3 is installed on the inner wall of the base 2, and a silicone sleeve 4 is fitted on the outer wall of the round rod 3 to ensure flexible rotation and no looseness. Next, the limiting mechanism 5 is installed, and the mounting frame 501 is fixed to the upper end of the base 2 with bolts. At the same time, the slide bar 502 and the limiting bar 503 are installed into the inside of the mounting frame 501 in sequence. The position of the limiting bar 503 is adjusted to accommodate PE pipes of different specifications. Finally, the traction mechanism 7 is installed, and the fixing frame 701 is fixed on the base 2. The straight rod 702 is combined with multiple evenly arranged traction blocks 703 and installed on the inner wall of the fixing frame 501. A motor 8 is added to the outside to complete the assembly of the overall structure.

[0026] During the preparation process, each component is inspected and debugged to ensure that all parts are undamaged and function properly. Special attention should be paid to whether the surfaces of the silicone sleeve 4 and the silicone roller 10 are smooth and free of defects to avoid scratching the PE pipe. In addition, it is necessary to confirm that the connection between the output shaft of the motor 8 and the round rod 703 is firm, and whether the position of the arc plate 6 of the limiting mechanism 7 can accurately limit the offset of the PE pipe. After the preparation work is completed, the smooth operation of the device can be tested by manually rotating the round rod 3.

[0027] During operation, the starter motor 8 drives the straight rod 702 to rotate, thereby driving the traction block 703 and the silicone roller 10 on its outer wall to apply a stable traction force to the PE pipe. At this time, the arc-shaped plate 6 in the limiting mechanism 5 plays a crucial role in ensuring that the PE pipe remains centered during the traction process, preventing bending or deformation. Operators should observe the equipment operation in real time, adjust the position of the limiting strip 503 in a timely manner to accommodate PE pipes of different diameters, and monitor the wear of the silicone sleeve 4 and the silicone roller 10 for timely replacement.

[0028] The cleaning process mainly focuses on the post-use maintenance of the equipment. First, turn off the power and wait for the equipment to completely stop operating. Then, disassemble the vulnerable parts in the limit mechanism 5 and traction mechanism 7, such as the silicone sleeve 4 and silicone roller 10, and clean the surface with a mild detergent to remove polyethylene residue or other impurities. For metal parts such as the base 2, mounting bracket 501, and fixing bracket 701, wipe them clean with a dry cloth. If necessary, apply rust-preventive oil to prevent rusting during long-term storage. Finally, reassemble all parts and store them properly in a dry and ventilated place, preparing them for the next use.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
