Description
Technical Field
[0001] This utility model belongs to the field of electrical engineering technology, specifically an anti-interference cable metal layer wrapping device. Background Technology
[0002] The main purpose of using anti-interference cables is to ensure the quality of signal transmission in harsh electromagnetic environments, improve the reliability of electrical equipment, and reduce the impact of electromagnetic interference and radio frequency interference on the equipment. The metal layer wrapping device can effectively prevent external electromagnetic interference from entering the cable, thereby ensuring the clarity and stability of the signal inside the cable.
[0003] The anti-interference cable metal layer wrapping device wraps the outer surface of the cable with the metal material to be wrapped. The metal material wrapped around the outside of the cable effectively blocks external electromagnetic interference from entering the inside of the cable, thereby avoiding interference from external electromagnetic waves on the signals transmitted inside the cable and providing strong support for the use of the cable.
[0004] Existing wrapping devices often take the cable out of the wire roller when wrapping it with a metal foil layer. However, because the cable will bend after being wound around the outside of the wire roller for a long time, when wrapping the bent cable, the wrapping device cannot evenly wrap the metal foil layer on the surface of the cable, causing electromagnetic interference. Therefore, an anti-interference cable metal layer wrapping device is proposed to address the above problems. Utility Model Content
[0005] To overcome the shortcomings of existing technologies, existing wrapping devices often take the cable out of the wire roller when wrapping the cable with metal foil. However, due to the cable being wound around the outside of the wire roller for a long time, it will bend. When wrapping the bent cable, the wrapping device cannot evenly wrap the metal foil layer on the surface of the cable, causing electromagnetic interference. This utility model proposes an anti-interference cable metal layer wrapping device.
[0006] The technical solution adopted by this utility model to solve its technical problem is an anti-interference cable metal layer wrapping device, including an operating table. Multiple supports are installed at both ends of the top of the operating table. A receiving roller and a feeding roller are respectively arranged between the multiple supports. An installation base and a fixing plate are respectively located at the center of the top of the operating table. An opening is formed inside the operating table, and the outside of the fixing plate is installed inside the opening. Multiple installation slots are formed at one end of the top of the installation base. Movable blocks are arranged inside each of the multiple installation slots. Multiple fixing rods are fixedly installed on the top of the installation base and the moving blocks. A straightening roller is rotatably installed on the top of each of the multiple fixing rods. Rotating blocks are rotatably installed at all four ends of one side of the fixing plate. The rotating blocks contain... A limiting groove is provided in the part, and an internal toothed turntable is provided between the multiple rotating blocks. The four outer ends of the internal toothed turntable are respectively located inside the limiting groove. The sawtooth end of the internal toothed turntable is meshed with a gear. A first drive motor is provided on the outer side of the gear. The output end of the first drive motor is installed on the outer side of the gear. The cable is driven to move by the take-up roller. During the movement, the cable is straightened by multiple straightening rollers. After the straightening is completed, the rotation of the internal toothed turntable drives the rotation of the rotating cylinder with the outer metal foil roller to wrap the outer surface of the cable. By straightening the cable during the wrapping process, uneven tension is avoided when wrapping the metal layer, ensuring that the metal layer is evenly wrapped on the surface of the cable and providing a good electromagnetic shielding effect.
[0007] Preferably, a first connecting plate is fixedly installed on the outer side of the internal gear turntable, and an internal threaded cylinder is fixedly installed on the outer side of the first connecting plate. A rotating cylinder is rotatably installed on the outside of the internal threaded cylinder, and the top of the rotating cylinder is tightly attached to a second connecting plate. A second threaded rod is rotatably installed inside the second connecting plate, and one end of the second threaded rod passes through the internal thread of the second connecting plate and is installed inside the internal threaded cylinder. The second connecting plate is removed by rotating the second threaded rod. When the second connecting plate is removed, the rotating cylinder is removed. The rotating cylinder can be removed to replace the metal foil after it is used up.
[0008] Preferably, one side of the mounting base is provided with a plurality of first threaded rods. One end of the first threaded rod passes through the internal thread of the mounting base and is installed inside the movable block. The end of the first threaded rod passes through the movable block and is rotatably installed inside the mounting base. The first threaded rod drives one of the two sets of straightening rollers to move. When the straightening roller moves to be close to the cable, the effect of straightening cables of different widths is achieved.
[0009] Preferably, a fixing plate is fixedly installed on the outer side of the fixing plate, the bottom of the first drive motor is fixedly installed on the top of the fixing plate, a fixing cylinder is fixedly installed on the bottom of the fixing plate, a plurality of springs are fixedly installed inside the fixing cylinder, and an arc-shaped plate is fixedly installed on the outer side of the spring away from the fixing cylinder. The plurality of arc-shaped plates are arranged in a circle. Through the elasticity of the plurality of arc-shaped plates inside the fixing cylinder and the springs themselves, the effect of fixing cables of different widths is achieved, preventing downward displacement before winding and resulting in uneven wrapping.
[0010] Preferably, multiple sliding blocks are fixedly installed on one side of both ends of the operating table. The outer side of the sliding blocks is slidably installed inside the bracket. The sides of two brackets are closely attached to baffles. The bottom end of the baffle is slidably installed inside the operating table. By pulling out the baffle, the bracket is driven to move backward. The backward movement of the bracket achieves the effect of removing the inserted receiving roller and one end of the receiving roller.
[0011] Preferably, a second drive motor is fixedly installed on the side of one of the brackets. The output end of the second drive motor passes through the interior of the bracket and is installed with a fixed rotating shaft. Multiple connecting rods are fixedly installed on the outer side of the fixed rotating shaft. Multiple connection ports are opened on one side of the receiving roller. The outer side of the connecting rod is located inside the connection port. When the receiving roller needs to be disassembled after receiving the material, the connection between the connecting rod and the connection port enables the receiving roller to rotate while pushing the receiving roller backward to achieve the effect of pulling out the receiving roller.
[0012] The advantages of this utility model are:
[0013] This invention addresses the problem of electromagnetic interference caused by unevenly wrapping the metal foil layer on the cable surface during the cable wrapping process using a wrapping device. The device uses a take-up roller to move the cable, and multiple straightening rollers straighten the cable during this movement. After straightening, an internal gear turntable rotates, driving an external rotating cylinder with a metal foil roller to wrap the cable surface. This solves the problem that existing wrapping devices often remove the cable from the roller for wrapping, which can lead to bending due to prolonged winding. When wrapping a bent cable, the device cannot evenly wrap the metal foil layer on the cable surface. By straightening the cable during the wrapping process, uneven tension is avoided during metal foil wrapping, ensuring the metal layer is evenly wrapped on the cable surface and providing good electromagnetic shielding.

[0022] 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 scope of protection of the present utility model.
[0023] Please see Figure 1-6As shown, an anti-interference cable metal layer wrapping device includes an operating table 1. Multiple supports 2 are mounted on both ends of the top of the operating table 1. A receiving roller 3 and a feeding roller 4 are respectively arranged between the multiple supports 2. An mounting base 5 and a fixing plate 6 are respectively located at the center of the top of the operating table 1. An opening is formed inside the operating table 1, and the outside of the fixing plate 6 is installed inside the opening. Multiple mounting slots 7 are formed on one end of the top of the mounting base 5. Movable blocks 8 are arranged inside each of the multiple mounting slots 7. Multiple fixing rods 11 are fixedly mounted on the top of the mounting base 5 and the moving blocks 8. A straightening roller 12 is rotatably mounted on the top of each of the multiple fixing rods 11. Rotating blocks 13 are rotatably mounted on all four ends of one side of the fixing plate 6. Limiting grooves are formed inside the rotating blocks 13. An internal gear turntable 14 is arranged between the multiple rotating blocks 13. The four ends of the internal gear turntable 14 are respectively located inside the limiting grooves. Gears 15 are meshed with the serrated ends of the internal gear turntable 14. The gear 15 has a first drive motor 17 on its outer side, and the output end of the first drive motor 17 is installed on the outer side of the gear 15. During operation, the existing wrapping device causes uneven wrapping when wrapping a bent cable due to the cable's tilt angle. In order to make the wrapping device wrap the cable more evenly, the device starts the second drive motor 21 to drive the fixed rotating shaft 22 to rotate. The rotation of the fixed rotating shaft 22 drives the take-up roller 3 to rotate. The take-up roller 3 retracts the cable outside the feed roller 4. During the retraction process, multiple straightening rollers 12 straighten the bent cable. Then, the first drive motor 17 is started to drive the gear 15 to rotate. The rotation of the gear 15 drives the internal gear turntable 14 to rotate. When the internal gear turntable 14 rotates, it drives the rotating cylinder 27 installed on one side to rotate in a circle. The metal foil roller located outside the rotating cylinder 27 wraps the outer surface of the cable being retracted into the take-up roller 3.
[0024] A first connecting plate 25 is fixedly installed on the outer side of the internal gear turntable 14. An internal threaded cylinder 26 is fixedly installed on the outer side of the first connecting plate 25. A rotating cylinder 27 is rotatably installed on the outside of the internal threaded cylinder 26. The top of the rotating cylinder 27 is tightly attached to a second connecting plate 28. A second threaded rod 29 is rotatably installed inside the second connecting plate 28. One end of the second threaded rod 29 passes through the internal thread of the second connecting plate 28 and is installed inside the internal threaded cylinder 26. During operation, existing wrapping devices cause uneven wrapping when wrapping curved cables due to the cable's tilt angle. To make the wrapping device wrap the cable more evenly, this device rotates the second threaded rod 29 to move and remove the second connecting plate 28. The removal of the second connecting plate 28 allows the rotating cylinder 27 to be removed, enabling the replacement of the metal foil roller.
[0025] The mounting base 5 has multiple first threaded rods 10 inside one side. One end of the first threaded rod 10 passes through the internal thread of the mounting base 5 and is installed inside the moving block 8. The end of the first threaded rod 10 passing through the moving block 8 is rotatably installed inside the mounting base 5. During operation, existing wrapping devices cause uneven wrapping when wrapping bent cables due to the tilt angle of the cable. In order to make the wrapping device wrap the cable more evenly, this device rotates the first threaded rods 10 to drive the moving block 8 to move back and forth. The back and forth movement of the moving block 8 drives one side of the two straightening rollers 12 to move, thereby achieving the effect of adjusting the straightening width.
[0026] A fixing plate 16 is fixedly installed on the outer side of the fixing plate 6. The bottom of the first drive motor 17 is fixedly installed on the top of the fixing plate 16. A fixing cylinder 18 is fixedly installed on the bottom of the fixing plate 16. Multiple springs 19 are fixedly installed inside the fixing cylinder 18. An arc-shaped plate 20 is fixedly installed on the outer side of the end of the spring 19 away from the fixing cylinder 18. The multiple arc-shaped plates 20 are arranged in a circle. During operation, the existing wrapping device causes uneven wrapping when wrapping curved cables due to the tilt angle of the cable. In order to make the wrapping device wrapping the cable more evenly, the multiple arc-shaped plates 20 and springs 19 inside the fixing cylinder 18 fix the moving cable and prevent it from shifting downwards before being wrapped.
[0027] Multiple sliding blocks 30 are fixedly installed on one side of both ends of the operating table 1. The outer side of the sliding block 30 is slidably installed inside the bracket 2. Both sides of the bracket 2 are tightly attached to the baffle 31. The bottom end of the baffle 31 is slidably installed inside the operating table 1. During operation, the existing wrapping device causes uneven wrapping when wrapping curved cables due to the tilt angle of the cable. In order to make the wrapping device wrap the cable more evenly, this device removes the baffle 31 inserted inside the operating table 1 to release the restriction on the bracket 2.
[0028] A second drive motor 21 is fixedly installed on the side of one of the brackets 2. The output end of the second drive motor 21 passes through the interior of the bracket 2 and is fitted with a fixed rotating shaft 22. Multiple connecting rods 23 are fixedly installed on the outer side of the fixed rotating shaft 22. Multiple connection ports 24 are opened on one side of the receiving roller 3. The outer side of the connecting rods 23 is located inside the connection ports 24. During operation, existing wrapping devices cause uneven wrapping when wrapping curved cables due to the inclination angle of the cables. In order to make the wrapping device wrapping cables more evenly, this device achieves the effect of rotating the receiving roller 3 by driving the receiving roller 3 through the second drive motor 21 while the receiving roller 3 is detachable, through the connection between the connecting rods 23 and the connection ports 24.
[0029] Working principle: During the cable wrapping process, when the wrapping device wraps a metal foil layer around the outer surface of the cable, the second drive motor 21 is activated to drive the fixed rotating shaft 22 to rotate. The rotation of the fixed rotating shaft 22 drives the take-up roller 3 to rotate, and the take-up roller 3 retracts the cable outside the feed roller 4. During the retraction process, multiple straightening rollers 12 straighten the bent cable. When it is necessary to straighten cables of different widths, the rotation of multiple threaded rods 10, which are threaded inside the moving block 8, drives multiple straightening rollers 12 on one side to move back and forth. The back and forth movement of multiple straightening rollers 12 on one side adjusts the straightening rollers. The effect of correcting the width between 12 is achieved by starting the first drive motor 17 to drive the gear 15 to rotate. The rotation of the gear 15 drives the internal gear turntable 14 to rotate. When the internal gear turntable 14 rotates, it will drive the rotating cylinder 27 installed on one side to rotate in a circle. The metal foil roller located outside the rotating cylinder 27 will wrap the outer surface of the cable that is being recycled into the take-up roller 3. When the take-up roller 3 has finished collecting the wrapped cable, the effect of limiting the bracket 2 is released by pulling out the baffle 31. Then, the take-up roller 3 and the feed roller 4 inserted inside the bracket 2 can be taken out by the sliding installation between the sliding block 30 and the bracket 2, so as to facilitate the winding of the next group of cables.
