[0002] Cable laying refers to the process of releasing materials such as wires, cables, and optical fibers from a cable reel or drum during industrial production or construction, and laying or connecting them to designated equipment along a certain path. Cable laying operations are widely used in power, communications, construction, and manufacturing. During the cable laying process, cable laying devices are required to ensure that the cables are released in an orderly manner and to avoid tangling or knotting.
[0003] In traditional wire feeding devices, the wire feeding reel is installed on the upper part of the wire feeding frame. Then, during wire feeding, the wire feeding reel is first installed on the upper part of the wire feeding frame. Next, one end of the cable is passed through the middle of the guide wheel and then through the tension wheel. Finally, it is installed on the equipment to be connected to complete the wire feeding operation.
[0004] Although existing cable-laying devices can complete the cable-laying operation, they cannot adjust the cable tension during the laying process. This results in the cable-laying device being unable to stably control the tension, causing the tension to fluctuate and thus affecting the laying efficiency. Utility Model Content

[0028] Reference Figures 1-5 This utility model provides an embodiment of a tension-stable cable feeding device structure, including a cable feeding frame 1. A horizontal plate 4 is fixedly connected to the right side of the cable feeding frame 1. A motor 6 is installed on the rear side of the cable feeding frame 1. A rotating rod 7 is fixedly connected to the output end of the motor 6. An installation cavity 21 is opened inside the rotating rod 7, and a disassembly assembly is installed inside the installation cavity 21. The disassembly assembly facilitates the replacement of the cable feeding reel 8. The cable feeding reel 8 is installed on the outside of the rotating rod 7. An installation plate 11 is fixedly connected to the outside of the horizontal plate 4. A tension adjustment assembly is provided on the upper part of the installation plate 11. The tension adjustment assembly facilitates the adjustment of the cable tension. A mounting ring 5 is fixedly connected to the rear side of the wire frame 1. A motor 6 is fixedly connected to the outside of the mounting ring 5. Guide blocks 9 are fixedly connected to both sides of the horizontal plate 4. Guide rings 10 are installed inside the two guide blocks 9. The guide rings 10 guide the cable. The two guide rings 10 are made of rubber. Rubber is soft and elastic, which can effectively reduce the friction between the cable and the guide rings 10. Fixing plates 2 are fixedly connected to both sides of the inside of the wire feeder 1. Mounting holes 3 are opened on both sides of the inside of the two fixing plates 2. The fixing plates 2 and mounting holes 3 facilitate the fixing of the wire feeder 1.
[0029] The tension adjustment assembly includes a mounting block 12, with a second motor 14 mounted on the outside of the mounting block 12. A gear 15 is fixedly connected to the output end of the second motor 14, and the gear 15 is rotatably connected inside the mounting block 12. A rack plate 16 is slidably connected inside the mounting block 12, meshing with the gear 15. Slider blocks 17 are fixedly connected to both sides of the rack plate 16. A connecting plate 19 is fixedly connected to the bottom of the rack plate 16, and a tension roller 20 is rotatably connected to the lower part of the connecting plate 19. The tension roller 20 facilitates adjustment. The tension of the cable is controlled by a fixing ring 13 fixedly connected to the outside of the mounting block 12. The motor 14 is fixedly connected inside the fixing ring 13. Both the mounting plate 11 and the mounting block 12 have through holes 29 inside. The rack plate 16 is slidably connected inside the through holes 29. The rack plate 16 can move by setting the through holes 29. Both sides of the mounting block 12 and the mounting plate 11 have sliding grooves 18. Two sliders 17 are slidably connected inside the two sliding grooves 18. The sliding grooves 18 facilitate the movement of the sliders 17.
[0030] Specifically, during cable laying, the cable laying reel 8 is first installed outside the rotating rod 7. Then, one end of the cable is pulled from the cable laying reel 8 and passes through the inside of the left guide block 9. The guide block 9 guides the direction of the cable, ensuring a stable path during laying and preventing deviation or tangling. Next, the cable passes under the tension roller 20. Finally, the cable exits through the inside of the right guide block 9, completing the cable laying path. When adjusting the cable tension, motor 2 14 is first started. Motor 2 14, through the gear 15 fixed at its output end, drives the externally meshing rack plate 16 downwards. The movement of the rack plate 16 causes the bottom-fixed connecting plate 19 to move downwards synchronously. A rotatable tension roller 20 is installed at the lower part of the connecting plate 19. As the connecting plate 19 moves downward, the tension roller 20 also moves downward, thereby driving the cable passing through it downward. In this way, the tension of the cable can be adjusted. When the cable tension is adjusted to a suitable level, the adjustment can be stopped by turning off the motor 14. This design realizes convenient adjustment of cable tension and solves the problem that traditional cable feeding devices cannot stably control cable tension during the feeding process. Through the design of motor 14, gear 15, rack plate 16, connecting plate 19 and tension roller 20, the tension of the cable can be controlled to ensure that it remains stable during the feeding process, thereby improving the efficiency of cable feeding.
[0031] Reference Figures 2-6 The assembly and disassembly components include a fixing rod 22, which is fixedly connected inside the mounting cavity 21. Sliding blocks 23 are slidably connected to both sides of the fixing rod 22. A spring 24 is fixedly connected to the middle of the two sliding blocks 23 and is sleeved on the outside of the fixing rod 22. Insert blocks 26 are fixedly connected to the outside of the two sliding blocks 23. A crossbar 25 is fixedly connected to the front side of the two sliding blocks 23. The crossbar 25 facilitates the use of the operator. A through hole 28 is opened on the front side of the rotating rod 7. The two crossbars 25 are slidably connected inside the two through holes 28. The through holes 28 facilitate the movement of the crossbars 25. Slots 27 are opened on both sides of the inside of the pay-off reel 8. The two insert blocks 26 are inserted into the two slots 27, which improves the stability of the pay-off reel 8 during installation.
[0032] Specifically, when the pay-off reel 8 needs to be replaced, firstly, the two crossbars 25 are moved relative to each other. The relative movement of the two crossbars 25 causes the two sliding blocks 23 fixed at the bottom to slide relative to each other outside the fixed rod 22. The movement of the sliding blocks 23 further causes the two insert blocks 26 fixed on both sides of their outer sides to move synchronously. During this process, the relative movement of the two sliding blocks 23 will compress the spring 24 fixed in the middle, causing the spring 24 to undergo elastic deformation under force. As the insert blocks 26 gradually disengage from the inside of the two slots 27, the connection between the pay-off reel 8 and the rotating rod 7 is released. At this time, the pay-off reel 8 can be removed from the rotating rod 7. The external part of the rotating rod 7 can be easily removed to complete the disassembly operation. When installing the new pay-off reel 8, first put the new pay-off reel 8 on the outside of the rotating rod 7. Then, loosen the two crossbars 25. At this time, the spring 24 returns to its original shape under the action of the reaction force, pushing the two sliding blocks 23 to move in the opposite direction. The movement of the sliding blocks 23 drives the two inserts 26 to re-insert into the two slots 27, thereby firmly fixing the pay-off reel 8 on the rotating rod 7 and completing the installation operation. The above method facilitates the disassembly and assembly of the pay-off reel 8. The operation is simple, convenient, time-saving and labor-saving, thereby improving the replacement efficiency of the pay-off reel 8.
[0033] Working principle: During cable feeding, firstly, the cable feeding reel 8 is installed outside the rotating rod 7. Then, one end of the cable is passed through the inside of the left guide block 9, then through the lower part of the tension roller 20, and finally out through the inside of the right guide block 9. Then, when adjusting the tension, firstly, the second motor 14 is started. The second motor 14 drives the gear 15 fixed at the output end to rotate. The rotation of the gear 15 drives the externally meshing rack plate 16 to move downward. The movement of the rack plate 16 drives the bottom fixed connecting plate 19 to move downward synchronously. The downward movement of the connecting plate 19 drives the lower rotating tension roller 20 to move synchronously. The downward movement of the tension roller 20 drives the lower cable to move downward. By moving the cable downward, the tension of the cable can be adjusted. When the appropriate force is reached, the second motor 14 is turned off. This makes it easy to adjust the tension of the cable and avoids the problem of unstable control of the cable tension during feeding, which leads to the problem of tension fluctuating. This improves the cable feeding efficiency.
[0034] When the pay-off reel 8 needs to be replaced, firstly, the two crossbars 25 are moved relative to each other. The relative movement of the two crossbars 25 causes the two sliding blocks 23 fixed at the bottom to move relative to each other outside the fixed rod 22. When the two sliding blocks 23 move relative to each other, the two insert blocks 26 fixed on the outer sides move synchronously. At the same time, the relative movement of the two sliding blocks 23 compresses the spring 24 fixed in the middle, causing the spring 24 to deform under force. Then, when the two insert blocks 26 disengage from the inside of the two slots 27, the pay-off reel 8 can be removed from the outside of the rotating rod 7 for replacement. During installation, the new pay-off reel 8 is placed on the outside of the rotating rod 7. Then, the two crossbars 25 are released, and under the reaction force of the spring 24, the two insert blocks 26 are inserted into the inside of the two slots 27 to complete the installation. This makes it easy to disassemble and assemble the pay-off reel 8, and the operation is simple, convenient, time-saving and labor-saving, thereby improving the replacement efficiency of the pay-off reel 8.
[0035] 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.
