Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable production technology, specifically to a tension adjustment device for cable production. Background Technology
[0002] During cable production, before wrapping the copper core with insulation and other protective layers, the cable tension needs to be adjusted to ensure that the cable tension is in a suitable state for installing the insulation layer, thereby improving the quality of cable production.
[0003] Utility model patent CN220564016U discloses a tension adjustment device for cable production equipment. It solves the problem of the complexity of adjusting multiple guide wheels required by existing tension adjustment devices, which typically involve placing a cable on multiple guide wheels, pulling the cable at one end while keeping the other end fixed, and then adjusting the position of the guide wheels to adjust the cable tension. The new device uses an electric telescopic rod that shortens until the first and second rotating wheels clamp the cable to a point where it can be driven to move. The motor's output shaft drives the first and second rotating wheels to rotate, thus moving the cable. When the distance between the cable and the sensor of the first detection mechanism is less than a set distance, the rotation speed of the first and second rotating wheels of the cable feeding mechanism is slowed down. This solves the problem of the complexity of adjusting multiple guide wheels. While this method has a simple structure, in actual use, the cable may shift in the front-to-back direction during transport, causing it to no longer be above the sensor, leading to reduced sensor measurement accuracy and poor tensioning effect.

[0019] 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.
[0020] like Figures 1 to 4As shown, a tension adjustment device for cable production includes a base 1. First support blocks 2 are fixedly connected to the front and rear sides of the top of the base 1. A second support block 3 is positioned above the first support blocks 2. A first rotating wheel 4 is rotatably connected between the two first support blocks 2, and a second rotating wheel 5 is rotatably connected between the two second support blocks 3. A first motor 6 is fixedly connected to the surfaces of both the first support blocks 2 and the second support blocks 3. The output end of the first motor 6 is fixedly connected to the first rotating wheel 4 and the second rotating wheel 5, respectively. An electric cylinder 7 is fixedly connected to the top of the first support block 2, and the output end of the electric cylinder 7 is fixedly connected to the second support block 3. A drive box 8 is fixedly connected to both sides of the top of the base 1. A threaded rod 9 with reverse threads is rotatably connected inside the drive box 8. Movable columns 10 are slidably connected to the front and rear sides of the drive box 8, and the movable columns 10 are threadedly connected to the threaded rod 9. A second motor 11 is fixedly connected to the front of the drive box 8, and the output end of the second motor 11 is fixedly connected to the threaded rod 9. A sensor 12 is fixedly connected to the top of the base 1.
[0021] refer to Figure 2 Rollers 13 are fixedly connected to the surface of the movable column 10.
[0022] As a technical optimization of this utility model, the setting of roller 13 can reduce the friction between the movable column 10 and the cable, thereby facilitating the cable to be transported to the right.
[0023] refer to Figure 2 The drive box 8 has a bearing fixedly connected inside, and the outer ring of the bearing is fixedly connected to the drive box 8, while the inner ring of the bearing is fixedly connected to the threaded rod 9.
[0024] As a technical optimization of this utility model, the friction between the drive box 8 and the threaded rod 9 can be reduced by setting the bearing, thereby facilitating the rotation of the threaded rod 9.
[0025] refer to Figure 4 The base 1 has a first fixing block 14 fixedly connected to the front and rear sides of the top two sides, and a first guide roller 15 rotatably connected between the two first fixing blocks 14. The base 1 has a second fixing block 16 fixedly connected to the front and rear sides of the top two sides, and a second guide roller 17 rotatably connected between the two second fixing blocks 16. The base 1 has a tension detector 18 fixedly connected to both sides of the top. The tension detector 18 has a limit rod 19 fixedly connected to the top. The limit rod 19 has a movable block 21 slidably connected to the surface of the limit rod 19. The movable block 21 has a third guide roller 22 rotatably connected to the surface of the movable block 21.
[0026] As a technical optimization of this utility model, through the arrangement of the first fixing block 14, the first guide roller 15, the second fixing block 16, the second guide roller 17, the tension detector 18, the limiting rod 19, the movable block 21, and the third guide roller 22, the cable passes sequentially through the top of the first guide roller 15, the bottom of the third guide roller 22, and the top of the second guide roller 17. When the cable is tensioned, the cable applies an upward tension to the third guide roller 22. The movable block 21 is slidably connected to the limiting rod 19, and the tension spring 20 is stretched, thereby playing a buffering role. When the third guide roller 22 is subjected to an upward tension, the tension detector 18 is indirectly subjected to an upward tension, thus indirectly reflecting the tension of the cable at this time. The greater the tension force on the cable, the greater the upward force detected by the tension detector 18. The aforementioned tension detector 18 is a common existing technology and is common knowledge to those skilled in the art, and will not be described in detail in this application.
[0027] refer to Figure 3 The second support block 3 is fixedly connected to both sides of the limit frame 23, and the first support block 2 is fixedly connected to both sides of the limit block 24. The top of the limit block 24 is provided with an opening, and the limit frame 23 is slidably connected to the opening.
[0028] As a technical optimization of this utility model, by setting up the limiting frame 23, the limiting block 24 and the opening, the limiting frame 23 slides up and down within the limiting block 24, thereby ensuring that the second support block 3 and the second rotating wheel 5 can move up and down stably.
[0029] refer to Figure 1 The base 1 has cylinders fixedly connected to all four sides of its bottom. The cylinders are threaded with a first threaded rod, and the bottom of the first threaded rod is fixedly connected with a support pad.
[0030] As a technical optimization of this utility model, by setting up a cylinder, a first threaded rod and a support pad, the operator can rotate the first threaded rod, thereby driving the first threaded rod and the support pad to move up or down, thereby adjusting the height or level of the base 1. The support pad is made of rubber material, and a level is fixedly connected to the surface of the base 1 (the level is not shown).
[0031] The working principle and usage process of this utility model are as follows: In use, the operator sequentially passes the cable between the left first rotating wheel 4 and the second rotating wheel 5, then through the left first guide roller 15, the third guide roller 22, and the second guide roller 17, then through the right second guide roller 17, the third guide roller 22, and the first guide roller 15, and finally between the right first rotating wheel 4 and the second rotating wheel 5. The operator can adjust the retraction of the electric cylinder 7, thereby causing the second support block 3 and the second rotating wheel 5 to move downwards, thus clamping the cable. Then, the first motor 6 is started to rotate, thereby causing the first rotating wheel 4 and the second rotating wheel 5 to rotate. The first rotating wheel 4 and the second rotating wheel 5 rotate in different directions, causing the cable to move to the right. In the side conveying process, sensor 12 can detect the distance between the cable and the sensor 12. For example, when the cable is not tensioned, the cable at the top of sensor 12 droops, and the distance between the top of sensor 12 and the cable is relatively close. This adjusts the rotation of the first motor 6 on the left, thereby adjusting the speed of the first wheel 4 and the second wheel 5 on the left, and thus adjusting the tension of the cable. The above cable tension adjustment principle and sensor 12 are similar to those of the cable tension adjustment principle and sensor 12 in the utility model patent with publication number CN220564016U, which discloses a tension adjustment device for cable production equipment. The same effect is achieved, and this application will not elaborate further.
[0032] The operator can start the second motor 11 to rotate, which will drive the positive and negative threaded rod 9 to rotate, thereby driving the two front and rear movable columns 10 to move closer to each other, and then driving the two front and rear rollers 13 to move closer to each other until the rollers 13 are in contact with the cable, thereby positioning the cable in the front and rear direction, thus ensuring that the sensor 12 can detect the cable in real time, thereby improving the tension adjustment effect of the device.
