Abstract
Description
Technical Field
[0001] This utility model belongs to the field of plastic pipe traction technology, and in particular relates to a plastic pipe synchronous traction machine. Background Technology
[0002] In the production and processing of plastic pipes, the traction machine plays a crucial role. Its core function is to pull newly produced plastic pipes at a preset speed and direction, laying a solid foundation for subsequent processes such as cutting and packaging. However, most traditional plastic pipe traction machines use belt-driven traction mechanisms, a design that has revealed several problems in practical applications.
[0003] Specifically, when a belt pulls plastic tubes, especially flexible plastic hoses, these tubes are prone to lateral displacement. This displacement not only leads to instability in the traction process but also has a direct negative impact on product quality, such as tube deformation and surface scratches. Furthermore, traditional belt-driven traction machines present significant difficulties in adjusting belt tension. Insufficient tension can cause belt slippage, affecting traction efficiency; while excessive tension can accelerate belt wear, shorten its lifespan, and increase equipment maintenance costs.
[0004] Therefore, it is essential to invent a synchronous traction machine for plastic pipes. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a synchronous traction machine for plastic pipes, including a traction workbench, a mounting plate, a lower traction mechanism, an upper traction mechanism, a manual lifting frame, rotating seats, bolts, and a limiting shaft. The mounting plate, fixedly installed above the traction workbench, is fixed to the lower traction mechanism, which is located below the upper traction mechanism. The upper traction mechanism is connected to the manual lifting frame installed on the traction workbench. Two rotating seats are provided at one end of the lower and upper traction mechanisms, and the rotating seats are fixedly installed on the traction workbench by bolts. A limiting shaft is rotatably installed on each rotating seat.
[0006] The lower traction mechanism and the upper traction mechanism have the same structure. The side plate of the lower traction mechanism is fixed to the mounting plate. One of the side plates of the upper traction mechanism is connected to the manual lifting frame, which is a linear screw lifting frame.
[0007] Preferably, the lower traction mechanism includes a side plate, a drive wheel, a drive component, an adjustment slot, and an adjustment block. There are two side plates, and a drive wheel is rotatably mounted on the inner side of one end of each side plate. The output end of the drive component fixedly mounted on the outside of one of the side plates is fixed to either end of the drive wheel. An adjustment slot is opened through each of the other ends of the two side plates, and an adjustment block is slidably mounted in each adjustment slot.
[0008] Preferably, an adjusting wheel is rotatably mounted on the two adjusting blocks, the adjusting wheel is located on the inner side of the other end of the two side plates, and a thick-walled belt is rotatably mounted on the drive wheel and the adjusting wheel, with a limit recess provided in the middle of the thick-walled belt.
[0009] Preferably, an adjusting screw is rotatably installed in one of the adjusting slots, and the adjusting screw is connected to the corresponding adjusting block by thread engagement; a sliding rod is fixedly installed in the other adjusting slot, and the sliding rod is slidably connected to the corresponding adjusting block.
[0010] Preferably, either end of the adjusting screw rotates outward and is fixed to its handwheel. The handwheel is located on the outside of one end of the handwheel, and the position of the handwheel does not interfere with the normal operation of the thick-walled belt.
[0011] Preferably, the limiting recess in the middle of the thick-walled belt is an arc-shaped recess, which is used to limit the lateral displacement of the plastic tube product.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] This utility model relates to a synchronous traction machine for plastic tubes. It innovatively employs a design in both the lower and upper traction mechanisms, using a drive wheel and adjusting wheel in conjunction with a thick-walled belt. A unique arc-shaped limiting recess is specially designed in the middle of the thick-walled belt. This unique design effectively solves the problem of lateral displacement that easily occurs in plastic tubes, especially soft plastic hoses, during traction. The arc-shaped limiting recess fits tightly against the tube body, ensuring stable movement of the plastic tube during traction. This not only significantly improves traction stability but also effectively reduces quality problems such as tube deformation and surface scratches caused by lateral displacement. This improvement not only enhances the structural integrity and appearance quality of the product but also ensures product consistency and high quality, laying a solid foundation for subsequent cutting, packaging, and other processes, thereby comprehensively improving overall production efficiency and product quality.
[0014] This utility model's traction machine also excels in adjusting belt tension. Through the flexible sliding of the adjusting block within the adjusting slot and the precise engagement of the adjusting screw and slide rod, the operator can easily and accurately adjust the belt tension according to specific parameters such as the material and diameter of the plastic tube and the traction speed. This design not only avoids belt slippage due to insufficient tension but also effectively reduces excessive belt wear caused by over-tensioning, thus significantly extending the belt's service life.

[0022] As attached Figure 1 To be continued Figure 3 As shown:
[0023] This utility model provides a synchronous traction machine for plastic pipes, including a traction workbench 1, a mounting plate 2, a lower traction mechanism 3, an upper traction mechanism 4, a manual lifting frame 5, a rotating seat 6, bolts 7, and a limiting shaft 8. The mounting plate 2, which is fixedly installed above the traction workbench 1, is fixed to the lower traction mechanism 3. The lower traction mechanism 3 is located below the upper traction mechanism 4, and the upper traction mechanism 4 is connected to the manual lifting frame 5 installed on the traction workbench 1. Two rotating seats 6 are provided at one end of the lower traction mechanism 3 and the upper traction mechanism 4. The rotating seats 6 are fixedly installed on the traction workbench 1 by bolts 7. A limiting shaft 8 is rotatably installed on each of the rotating seats 6.
[0024] Furthermore, the lower traction mechanism 3 and the upper traction mechanism 4 share the same structural design, ensuring synchronization and stability during the traction process. The side plate 31 of the lower traction mechanism 3 is firmly fixed to the mounting plate 2, forming a stable support structure. One side plate 31 of the upper traction mechanism 4 is connected to the manual lifting frame 5, which is a linear screw lifting frame, allowing the height of the upper traction mechanism 4 to be flexibly adjusted as needed to accommodate the traction requirements of plastic pipes of different diameters.
[0025] Furthermore, the lower traction mechanism 3 includes side plates 31, drive wheels 32, drive components 33, adjustment slots 34, and adjustment blocks 35. Drive wheels 32 are rotatably mounted on the inner side of one end of each of the two side plates 31; these drive wheels 32 are the main components for traction of the plastic tube. A drive component 33 is fixedly mounted on the outside of one of the side plates 31, with its output end connected to one end of the drive wheel 32, providing power to the drive wheel 32. Adjustment slots 34 are formed at the other ends of both side plates 31, and adjustment blocks 35 are slidably mounted within these slots 34, allowing for subsequent adjustments.
[0026] Furthermore, adjusting wheels 36 are rotatably mounted on the two adjusting blocks 35. These adjusting wheels 36 are located on the inner side of the other end of the two side plates 31, cooperating with the drive wheel 32. A thick-walled belt 310 is fitted onto the drive wheel 32 and the adjusting wheels 36. The thick-walled belt 310 is the direct medium for traction of the plastic tube. Specifically, a limiting recess 311 is provided in the middle of the thick-walled belt 310. This limiting recess 311 is arc-shaped, and its function is to effectively limit the lateral displacement of the plastic tube product during traction, ensuring the stability and accuracy of traction.
[0027] Furthermore, to achieve flexible adjustment of the tension of the thick-walled belt 310, an adjusting screw 37 is rotatably installed in one of the adjusting slots 34, and the adjusting screw 37 is connected to the corresponding adjusting block 35 via threaded engagement. A sliding rod 38 is fixedly installed in the other adjusting slot 34, and the sliding rod 38 is slidably connected to the corresponding adjusting block 35. This design allows the operator to move the adjusting block 35 by rotating the adjusting screw 37, thereby adjusting the distance between the drive wheel 32 and the adjusting wheel 36, and thus adjusting the tension of the thick-walled belt 310.
[0028] Furthermore, one end of the adjusting screw 37 extends outwards and is fixed to its handwheel 39. This handwheel 39 is positioned on the outer side of one end, its location being rationally designed to avoid interfering with the normal operation of the thick-walled belt 310. Operators can easily adjust the tension of the thick-walled belt 310 by rotating the handwheel 39, making the traction process more stable and efficient.
[0029] The working principle is as follows: First, the plastic tube passes through two vertically parallel limiting shafts 8. These two limiting shafts 8 initially limit and guide the plastic tube to ensure that it is in the correct position and state before entering the traction mechanism.
[0030] Next, the plastic tube enters between the lower traction mechanism 3 and the upper traction mechanism 4. When the drive component 33 is activated, the drive wheel 32 begins to rotate, transmitting power to the adjusting wheel 36 via the thick-walled belt 310, thereby achieving traction of the plastic tube. The thick-walled belt 310 is the direct medium for traction of the plastic tube, and a limiting recess 311 is provided in its middle. This limiting recess 311 is arc-shaped and fits tightly against the surface of the plastic tube, effectively limiting the lateral displacement of the plastic tube during traction. This design not only improves the stability of traction but also reduces quality problems such as tube deformation and surface scratches caused by lateral displacement.
[0031] Meanwhile, to achieve flexible adjustment of the tension of the thick-walled belt 310, an adjusting screw 37 is rotatably installed in one adjusting slot 34 of the lower traction mechanism 3 and the upper traction mechanism 4. The adjusting screw 37 is connected to the corresponding adjusting block 35 via threaded engagement. A sliding rod 38 is fixedly installed in the other adjusting slot 34, and the sliding rod 38 is slidably connected to the corresponding adjusting block 35. The operator can rotate the adjusting screw 37 to push or pull the adjusting block 35, thereby adjusting the distance between the drive wheel 32 and the adjusting wheel 36, and thus achieving precise adjustment of the tension of the thick-walled belt 310.
[0032] Finally, through the synchronous traction of the upper and lower traction mechanisms, the plastic tube is stably transported to subsequent cutting, packaging, and other processes, completing the entire production process. Throughout the traction process, innovative designs such as the limiting shaft 8, the thick-walled belt 310 and its limiting recess 311, and the flexible tension adjustment mechanism make the traction process more stable and efficient, and significantly improve product quality.
[0033] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
