Description

Technical Field

[0001] This utility model relates to the field of cable stranding machine technology, and in particular to an anti-wear tension control device for cable stranding machines. Background Technology

[0002] In cable production, the stranding process is crucial for ensuring the stability and electrical performance of the cable structure. Tension control is one of the core technologies in stranding. Stable tension ensures a compact cable structure and uniform pitch after stranding, preventing quality problems such as loose strands, broken wires, or excessive stretching. However, during tension adjustment, the cable's contact with equipment components can easily generate friction and wear, affecting not only the cable's surface quality and lifespan but also accelerating equipment wear and increasing maintenance costs. Therefore, developing a cable stranding machine device that combines precise tension control with wear prevention is of great significance for improving cable production quality and reducing production costs.

[0003] Existing devices lack effective anti-wear structural design. During transmission and tension adjustment, the wires often experience rigid friction with the fixed guide components or tension adjustment components of the equipment. As the usage time increases, not only does the wear problem on the surface of the wires become more serious, but it also leads to accelerated wear of equipment components, shortens the service life of the equipment, and increases production and maintenance costs. In addition, the spacing of the adjustment components of some tension control devices is fixed and cannot be flexibly adjusted according to the number or specifications of the wires. Utility Model Content

[0004] Therefore, it is necessary to provide an anti-wear tension control device for cable stranding machines to address the aforementioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An anti-wear tension control device for a cable stranding machine, comprising:

[0007] A base plate, a winding device is installed on one side of the top of the base plate, a lifting device is located in the middle of the top of the base plate, a lifting tension adjustment frame is connected to the lifting device, and a roller is rotatably connected to one side of the inner wall of the lifting tension adjustment frame.

[0008] The inner wall of the lifting tension adjustment frame has a pair of movable holes at the top and bottom. T-shaped blocks are slidably connected to the inner wall of the movable holes. A connecting rod is fixedly connected between the two T-shaped blocks on the same side. An arc plate is provided on one side of the connecting rod. A roller is rotatably embedded in the arc surface of the arc plate. A spring is provided between the arc plate and the connecting rod. A spacing adjustment component is provided at the top of the lifting tension adjustment frame. A cable guide device is installed on the other side of the top of the bottom plate.

[0009] As a preferred embodiment of the anti-wear tension control device for cable stranding machine provided by this utility model, the spring member includes a crossbar fixed to the top and bottom of the inner wall of the arc plate, and one end of the crossbar slides through the surface of the connecting rod on the same side.

[0010] In a preferred embodiment of the anti-wear tension control device for a cable stranding machine provided by this utility model, a spring is sleeved on the portion of the crossbar located between the connecting rod and the arc plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The anti-wear tension control device for cable stranding machines provided by this utility model provides dual protection in anti-wear design. By rotatably embedding rollers on the arc surface of the arc plate, the rigid friction during wire transmission and tension adjustment is transformed into rolling friction of the rollers, which greatly reduces the wear on the wire surface and the wear of equipment components. At the same time, the rollers and the arc plate can restrict the left and right movement of the cable on the rollers, avoiding surface damage caused by additional friction due to cable deviation. The dual protection not only ensures the appearance and structural integrity of the cable, but also extends the service life of the equipment and reduces production and maintenance costs. The spring between the arc plate and the connecting rod can work with the rollers to form an elastic buffer.

[0017] 2. This utility model provides an anti-wear tension control device for a cable stranding machine. The spacing adjustment component drives the transmission block and T-block to slide along the moving hole through a bidirectional threaded rod, which can flexibly adjust the spacing between the two side arc plates and the roller, easily adapting to the processing requirements of different quantities and specifications of wires. It significantly improves the device's adaptability to diverse cable production processes, and the operation process is simple. It can improve the efficiency of cable stranding while ensuring processing quality, providing stable and reliable equipment support for cable production. Attached Figure Description

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] Example 1

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A wear-resistant tension control device for a cable stranding machine includes a base plate 1, and a winding device 2 is installed on one side of the top of the base plate 1 to wind up and store the stranded cable. Through a stable winding action, combined with a tension control system, it achieves orderly cable winding and unwinding, avoiding problems such as messy accumulation and tangling of cables after processing. A lifting device 3 is located at the top center of the base plate 1, driving the lifting tension adjustment frame 4 to move up and down. By adjusting the frame height, the tension reference value of the cable in the transmission path can be changed, adapting to the initial tension requirements of different cable specifications, thereby assisting in precise tension control and preventing cable stretching or slackness due to improper initial tension. This improves the flexibility and adaptability of tension adjustment. The lifting device 3 is connected to the lifting tension adjustment frame 4 via a transmission mechanism. A roller 5 is rotatably connected to one side of the inner wall of the lifting tension adjustment frame 4, providing rolling support for cable transmission and reducing direct friction between the cable and the frame. On the other hand, it works with the arc plate 9 to form a limiting structure, restricting the cable from moving left and right along the axis of the roller 5 during transmission, preventing cable deviation and additional friction that could cause surface damage. Simultaneously, its own rotation assists in smooth cable transmission, further reducing the risk of wear, making it an important component of dual wear protection.

[0029] The inner wall of the lifting tension adjustment frame 4 has a pair of movable holes 6 at both the top and bottom, providing sliding guide channels for the T-blocks 7. The precise hole design ensures that the T-blocks 7 slide along a fixed trajectory during spacing adjustment, preventing misalignment of the arc plate 9 and roller 10 due to T-block 7 displacement, thus ensuring the accuracy of spacing adjustment. This is the structural basis for flexible adjustment of the arc plate 9 spacing. T-blocks 7 are slidably connected to the inner wall of the movable holes 6, and a connecting rod 8 is fixedly connected between two T-blocks 7 on the same side. An arc plate 9 is provided on one side of the connecting rod 8, which, through its arc structure, cooperates with the roller 5 to form a wrapping limit on the cable, further restricting the cable's left movement. The rightward offset enhances the wear resistance. The arc surface of the arc plate 9 is rotatably embedded with a roller 10. During cable transmission and tension adjustment, the roller 10 contacts the cable surface and rotates synchronously with the cable movement, converting the rigid friction between the cable and the device into rolling friction, which greatly reduces the wear on the cable surface and the wear of its own components. A spring 11 is provided between the arc plate 9 and the connecting rod 8. A spacing adjustment component 12 is provided on the top of the lifting tension adjustment frame 4, which is the power component for flexibly adjusting the spacing of the arc plate 9. A cable guide device 13 is installed on the other side of the top of the base plate 1 to guide and position the cable before it enters the tension adjustment stage.

[0030] Preferably, the spring member 11 includes a crossbar 111 fixed to the top and bottom of the inner wall of the arc plate 9. One end of the crossbar 111 slides through the surface of the connecting rod 8 on the same side. A spring 112 is sleeved on the part of the crossbar 111 placed between the connecting rod 8 and the arc plate 9. A fixing block 113 is fixedly connected to one end of the crossbar 111 to provide elastic buffering. When the cable tension fluctuates, the pressure generated by the cable on the roller 10 pushes the arc plate 9 to squeeze the spring 112. The spring 112 absorbs the pressure through deformation, thereby buffering the tension fluctuation.

[0031] Preferably, the spacing adjustment component 12 includes top blocks 121 fixed to both sides of the top of the lifting tension adjustment frame 4. A bidirectional threaded rod 122 is rotatably connected between the two top blocks 121. Two opposite threads are distributed at both ends of the bidirectional threaded rod 122. Both ends of the bidirectional threaded rod 122 are threadedly connected to transmission blocks 123. The two transmission blocks 123 are respectively fixedly connected to the two T-shaped blocks 7 at the top. One end of the bidirectional threaded rod 122 passes through the surface of one top block 121 through a bearing, extends to its outer side, and is fixedly connected to a knob 124. Rotating the bidirectional threaded rod 122 realizes convenient adjustment of the spacing, ultimately adapting to the processing needs of different quantities and specifications of cables and improving the applicability of the device.

[0032] The operation of the anti-wear tension control device for a cable stranding machine provided by this utility model is as follows: First, the cable to be processed is guided and positioned by the cable guide device 13 on the other side of the top of the base plate 1, and then enters the lifting tension adjustment frame 4 at a stable angle. It first contacts and passes around the roller 5 on one side of the inner wall. The roller 5 provides rolling support for the cable by rotating on its own, and at the same time cooperates with the arc plate 9 to limit the left and right deviation of the cable. Then the cable passes between the two arc plates 9. The roller 10 embedded in the arc surface of the arc plate 9 contacts the surface of the cable. When the cable is transmitted, the roller 10 rotates synchronously with the cable movement, converting rigid friction into rolling friction. In the tension adjustment stage, if it is necessary to adjust the initial tension, the lifting tension adjustment frame 4 can be driven up and down by the lifting device 3 to change the tension reference value of the cable transmission path. When the cable tension exceeds the limit, the tension adjustment frame 4 can be adjusted up and down. When the cable fluctuates, the pressure of the cable on the roller 10 pushes the arc plate 9 to squeeze the spring 112 in the spring component 11. The spring 112 absorbs the pressure through deformation to achieve buffering, and the crossbar 111 provides extension and contraction guidance for the spring 112. The fixing block 113 prevents the crossbar 111 from disengaging from the connecting rod 8. If it is necessary to adapt to different quantities and specifications of cables, the knob 124 of the spacing adjustment component 12 can be rotated to drive the bidirectional threaded rod 122 to rotate. Because the threads at both ends of the bidirectional threaded rod 122 are opposite, the transmission block 123 on its surface will move synchronously towards or away from each other, thereby driving the top T-shaped block 7 to slide along the moving hole 6. The T-shaped block 7 drives the arc plate 9 and the roller 10 to adjust the spacing through the connecting rod 8. Finally, the cable after tension adjustment and anti-wear treatment is stably wound up by the winding device 2 on one side of the top of the base plate 1, completing the entire processing process.
