[0002] In the processing of textile fabrics, cable production, and the handling of continuous materials such as plastic films and metal foils, tension control devices are a crucial component in ensuring smooth material transport, dimensional accuracy, and surface quality. These devices typically employ multiple tension guide rollers to guide the material along a predetermined path, and, in conjunction with a tension detection and adjustment system, achieve stable tension control throughout the entire production process.

[0003] With the diversification of manufacturing processes, different batches of products exhibit significant differences in parameters such as size, thickness, and flexibility, placing varying requirements on the position, angle, and surface friction characteristics of the guide rollers. However, most existing tension control devices employ a universal tension guide roller structure, lacking a mechanism for rapid adjustment and replacement. This makes it difficult to quickly adapt to new material properties when changing products, thus affecting tension control accuracy and production efficiency. This problem is particularly prominent in flexible manufacturing scenarios requiring frequent changes in product specifications. Therefore, a tension control device is proposed to address these issues. Utility Model Content

[0033] 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.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a tension control device, including a back plate 1. A cooling pool 20 is fixedly connected to the bottom of the back plate 1, and the cooling pool 20 contains coolant for cooling the product. A cooling assembly is installed on the outside of the cooling pool 20, and a traction mechanism 2 is installed on the outside of the back plate 1. The traction mechanism 2 is used to traction the product to achieve product transportation. A tension adjustment assembly is installed inside the back plate 1. Multiple sets of guide assemblies are installed on the front of both the back plate 1 and the tension adjustment assembly. A processing part 26 is sleeved on the outside of the guide assembly. The processing part 26 can be a cable or fabric. The guide assembly and tension adjustment assembly are changed according to different products.

[0035] Reference Figures 3-4 The guide assembly includes a rotating block 3, which is rotatably connected to the front side of the back plate 1. A rotating rod 4 is fixedly connected to the front side of the rotating block 3. A guide ring 7 is sleeved on the outer side of the rotating rod 4. The workpiece 26 is wound around the outer side of the guide ring 7. The guide assembly guides the workpiece 26. After being guided by multiple sets of guide assemblies, it can ensure that the workpiece 26 can be effectively tensioned. A snap-fit ​​assembly is installed inside the rotating rod 4. The snap-fit ​​assembly allows the guide ring 7 to be quickly replaced to accommodate different workpieces 26. The snap-fit ​​assembly includes a pressure rod 8, which is slidably connected inside the rotating rod 4. A locking block 10 is slidably connected to the outer side of the rotating rod 4. A connecting rod 9 is rotatably connected to the inner side of the locking block 10. The other end of the connecting rod 9 is rotatably connected to the outer side of the pressure rod 8. When the guide ring 7 needs to be replaced, simply press the pressure rod 8 inward to move it. While moving, the connecting rod 9 rotates, and the locking block 10 is retracted into the rotating rod 4. At this time, the guide ring 7 can be pulled out from the outside of the rotating rod 4 to complete the replacement of the guide ring 7. A second spring 11 is fixedly connected to the end of the pressure rod 8. The other end of the second spring 11 is fixedly connected to the inside of the rotating rod 4. The second spring 11 is used to reset the locking block 10. After the new guide ring 7 is installed on the outside of the rotating rod 4, the pressure rod 8 is released and the locking block 10 is pushed out again under the action of the second spring 11 to complete the positioning of the guide ring 7.

[0036] A spring 5 is fixedly connected to the outside of the rotating block 3. A top block 6 is fixedly connected to the other end of the spring 5. The top block 6 is slidably connected to the outside of the rotating rod 4. After the guide ring 7 is sleeved on the outside of the rotating rod 4, it will first contact the top block 6 and squeeze the spring 5. At this time, when the other end of the guide ring 7 protrudes from the locking block 10, the guide ring 7 can be restricted by the locking block 10. The spring 5 and the top block 6 can keep the guide ring 7 stable. A positioning rod 12 is fixedly connected to the outside of the rotating rod 4. The guide ring 7 and the top block 6 are both slidably connected to the outside of the positioning rod 12. The positioning rod 12 restricts the position of the guide ring 7 and the top block 6 to ensure that the guide ring 7 and the rotating rod 4 rotate synchronously.

[0037] Reference Figures 1-2 The tension adjustment assembly includes an adjustment block 14, which is slidably connected to the middle of the back plate 1. A guide roller is mounted on the outer side of the adjustment block 14. When the adjustment block 14 moves, the guide roller changes the stroke of the workpiece 26, thus adjusting the tension of the workpiece 26. A servo motor 15 is fixedly connected to the rear side of the back plate 1. A worm gear 17 is fixedly connected to the output end of the servo motor 15. A threaded rod 13 is rotatably connected to the middle of the back plate 1. A worm wheel 16 is fixedly connected to the top of the threaded rod 13. The worm wheel 16 and the worm gear 17 mesh with each other. The adjustment block 14 is threadedly connected to the outer side of the threaded rod 13. By driving the servo motor 15, the worm gear 17 rotates, which, in conjunction with the worm wheel 16, causes the threaded rod 13 to rotate, thus changing the position of the adjustment block 14. Simultaneously, the worm gear 17 and worm wheel 16 also reduce the speed of the servo motor 15, further improving the adjustment accuracy to adapt to different tension adjustments of the workpiece 26. The back plate 1 has a positioning groove 19 inside, and a positioning block 18 is fixedly connected to the outside of the adjusting block 14. The positioning block 18 is slidably connected in the middle of the positioning groove 19. The positioning groove 19 and the positioning block 18 restrict the position of the adjusting block 14 to ensure the stability of the movement of the adjusting block 14.

[0038] Reference Figure 1 and Figure 5The cooling assembly includes an aeration plate 23, which is fixedly connected inside the cooling pool 20. The cooling pool 20 contains coolant. When the workpiece 26 needs to be cooled, it is passed around the outside of the guide roller inside the cooling pool 20, allowing the traction mechanism 2 to perform the cooling operation. A cooling box 21 is fixedly connected to the outside of the cooling pool 20, and an air pump 22 is fixedly connected to the outside of the cooling box 21. The output end of the air pump 22 is connected to the inside of the cooling box 21. After prolonged use, the temperature of the coolant gradually increases. At this time, the air pump 22 pumps gas into the cooling box 21, which is then transported to the aeration plate 23 through the cooling box 21, thus aerating the coolant inside the cooling pool 20 and accelerating its cooling. Multiple thermoelectric coolers 24 are fixedly connected to the outside of the cooling box 21. The cooling side of the thermoelectric coolers 24 is located inside the cooling box 21. The operation of the thermoelectric coolers 24 cools the air inside the cooling box 21, thereby further improving the heat dissipation of the coolant inside the cooling pool 20. A cooling fan 25 is fixedly connected to the top of the cooling box 21. The exhaust side of the cooling fan 25 faces the heat-generating side of the thermoelectric coolers 24. The cooling fan 25 handles the heat generated by the thermoelectric coolers 24 during operation, thereby improving the working efficiency of the thermoelectric coolers 24 and ensuring the long-term operation of the cooling components.

[0039] Working principle: In use, the workpiece 26 requiring tension control passes sequentially around the outside of multiple guide rings 7, and is then pulled by the traction mechanisms 2 on both sides for tension control. When tension adjustment is required, the servo motor 15 is driven to rotate the worm gear 17, which in turn rotates the worm wheel 16. At this time, the worm wheel 16 drives the threaded rod 13 to rotate, causing the adjusting block 14 to move up and down along the positioning groove 19. This adjusts the up and down movement of one set of guide rollers, thereby adjusting the tension of the entire device to adapt to the thickness and flexibility requirements of different batches of products. Secondly, a tension sensor can be installed on the front side of the back plate 1, and the workpiece 26 passes through the outside of the tension sensor to detect the tension of the workpiece 26 in real time, and adjust the tension in conjunction with the servo motor 15. The tension sensor is existing technology and is used as a supplement to the solution in this application, so it will not be described in detail here.

[0040] In the production of cables, fabrics, etc., cooling equipment is used. At this time, the workpiece 26 is passed through the guide roller inside the cooling pool 20. The coolant inside the cooling pool 20 is used to cool the workpiece 26. Air pump 22 is used to fill the cooling box 21 with air, and semiconductor refrigeration chip 24 is used to cool the air inside the cooling box 21. The cooled air enters the aeration plate 23 from the bottom pipe of the cooling box 21 and is injected into the cooling pool 20 from the top of the aeration plate 23. In this way, the coolant is cooled to improve the cooling effect on the workpiece 26.

[0041] When changing product batches or products, the pressure rod 8 can be pressed in the direction of the rotating rod 4, causing the pressure rod 8 to move inward and drive the connecting rod 9 to rotate. This causes the locking block 10 to retract into the rotating rod 4, at which point the guide ring 7 can be removed from the outside of the rotating rod 4 to replace it with a new guide ring 7. After the new guide ring 7 is inserted from the outside of the rotating rod 4, it can be quickly installed with the spring 5 and the top block 6. This can better adapt to the tension adjustment and conveying requirements of the new product.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
