When producing cables, tensioning equipment is usually required to tension and pull the cables in production so that the cables maintain a suitable tension for transportation and production. However, most of the tension adjustment devices currently used in cable production are fixed-point adjustment methods, which can usually only pull and tension the cables at a specified tension. The adjustment process does not have the ability to buffer and automatically adjust, which can easily cause the risk of breaking the cable. To this end, those skilled in the art provide a tension adjustment device for cable production to solve the problems raised in the above background technology. Utility Model Content

[0024] Please refer to Figure 1-5As shown, a tension adjustment device for cable production includes a support frame 1, and the support frame 1 is a T-shaped structure. Both ends of the cross frame of the support frame 1 are installed with a cable traction mechanism 2. The cable traction mechanism 2 includes a traction frame 21. The upper half of the traction frame 21 is symmetrically connected to two groups of traction rollers 22, and the lower half of the traction frame 21 is rotatably connected to a clamping screw rod 25. The outer side of the shaft rod of the clamping screw rod 25 is symmetrically sleeved with two groups of clamping slides 26 guided by the traction frame 21, and the upper end of the frame of each group of clamping slides 26 is connected There is a limiting roller 23 between the two groups of traction rollers 22, and an adjusting handle 24 is installed at one end of the shaft of the clamping wire rod 25. The clamping wire rod 25 is bounded by the center line, and positive and negative thread teeth that are compatible with the two groups of clamping slides 26 are symmetrically arranged on both sides of the center line. By rotating the adjusting handle 24, the clamping wire rod 25 is driven to rotate, and the positive and negative thread teeth are used to push the two groups of clamping slides 26 to slide symmetrically, and the spacing between the two groups of limiting rollers 23 is clamped and adjusted to clamp and limit cables of different thicknesses, so that they maintain a stable traction and transportation state.

[0025] The vertical frame of the support frame 1 is installed with a lifting and lowering adjustment mechanism, which includes a lifting guide rail 3 symmetrically installed at the front end of the support frame 1 and a fixed swivel seat 7 symmetrically installed on the back plate of the support frame 1. A lifting screw rod 8 is installed between the two sets of fixed swivel seats 7. A lifting motor 6 fixed to the support frame 1 is provided at the top end of the shaft of the lifting screw rod 8, and a lifting slide 4 guided by the lifting guide rail 3 is sleeved on the outer side of the shaft of the lifting screw rod 8. The support plate surface of the support frame 1 is horizontal to the shaft direction of the lifting screw rod 8 and is provided with a track groove 9 adapted to the lifting slide 4. By controlling the operation of the lifting motor 6, the lifting screw rod 8 is driven to rotate, and the lifting slide 4 is pushed to lift and slide along the track direction of the lifting guide rail 3, thereby driving the cable tensioning mechanism 5 to lift and slide, and dynamically adjusting the tension of the cable in production and transportation, so that the cable maintains appropriate tension for production and transportation.

[0026] The lifting platform of the lifting adjustment mechanism is equipped with a cable tensioning mechanism 5, which includes a tension frame 51. The bracket of the tension frame 51 is symmetrically equipped with an arm force guide rod 54. Both ends of the arm of the arm force guide rod 54 are slidably connected with a guide slide 53. The front end of each set of guide slides 53 is connected to a tension wheel 55. The outer side of the arm of the arm force guide rod 54 is sleeved with a guide slide 53. The guide slide 53 is elastically pressed against the arm force guide rod 54 by a compression spring 52. By using the compression spring 52 as a guide slide 53 and the arm The elastic supporting component between the force guide rods 54, when the tension wheel 55 is subjected to the tensioning force of the cable, its tensioning force can be transmitted to the guide slide 53 through the tension wheel 55, pressing the compression spring 52 to compress the elastic force, so that the two groups of tension wheels 55 maintain elasticity and dynamic tensioning performance, and adjust the tension of the cable in transportation. On the one hand, it has good elastic buffering performance, which can reduce the rigid tension in the production and transportation of the cable. On the other hand, it has good self-adjusting tension adaptation performance, which can keep the cable at appropriate tension during production and transportation.

[0027] The working principle of the utility model is as follows: when the tension of the cable in production is adjusted, the cable is pulled out from above the traction roller 22 in one group of cable traction mechanisms 2, then pulled out from the bottom of the tension wheel 55 in the cable tensioning mechanism 5, and then pulled out from above the traction roller 22 in the other group of cable traction mechanisms 2, so that it is pulled and hung on the tension adjustment device;

[0028] Furthermore, by rotating the adjustment handle 24, the clamping screw rod 25 is driven to rotate, and the positive and negative screw teeth thereof are used to push the two sets of clamping slides 26 to slide symmetrically, and the spacing between the two sets of limiting rollers 23 is adjusted to clamp and limit the cable on the traction roller 22, so that it maintains a stable traction and conveying state;

[0029] During the subsequent cable production and transportation, the lifting motor 6 can be controlled to drive the lifting screw 8 to rotate, and the lifting slide 4 can be pushed to lift and slide along the track direction of the lifting guide rail 3, thereby driving the cable tensioning mechanism 5 to lift and slide, so as to dynamically adjust the tension of the cable in production and transportation. During the lifting and moving process of the cable tensioning mechanism 5, when its tension wheel 55 is subjected to the tensioning force of the cable, its tensioning force is transmitted to the guide slide 53 through the tension wheel 55, and the compression spring 52 is compressed by the elastic force, so that the two groups of tension wheels 55 maintain elasticity and dynamic tensioning performance, and dynamically tension the cable in transportation is adjusted. It has good elastic buffering performance, which can reduce the rigid tensioning force in the production and transportation of the cable, and at the same time has good self-adjusting tensioning adaptation performance, which can keep the cable in suitable tensioning production and transportation, and is more flexible and adaptable to the tension adjustment of the cable.
