Description

Technical Field

[0001] This utility model relates to the field of cable conductor stranding technology, and in particular to a cable conductor stranding tension control device. Background Technology

[0002] Conductor stranding is the most common process in cable conductor production. The conductors of most low-voltage, medium-voltage, high-voltage, and ultra-high-voltage cables are produced using this method. Conductor stranding involves twisting multiple circular monofilaments around the center line of the strand in layers to form a structure similar to hemp rope. In the existing cable conductor stranding process, tension control is the key factor affecting the stranding accuracy and stability.

[0003] Traditional devices require each conductor to be equipped with a tension component (such as an independent magnetic powder brake), and manual calibration is required for each conductor during debugging. This is cumbersome and can easily lead to uneven conductor tension and loose structure after stranding due to parameter differences. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies and provide a cable conductor stranding tension control device.

[0005] Therefore, this utility model provides a cable conductor stranding tension control device, including a base plate, a rotating shaft above the base plate, a first wire reel fixedly connected to the outer surface of the rotating shaft, a plurality of wire feeding rollers movably mounted on the side wall of the first wire reel, a second wire reel fixedly connected to the outer surface of the rotating shaft, a plurality of wire feeding grooves formed on the side wall of the second wire reel, a rotating disk movably mounted on the side wall of the second wire reel, a plurality of inclined grooves formed on the side wall of the rotating disk, a movable pin movably mounted inside the inclined groove, a pressing plate fixedly connected to the side wall of the movable pin, a connecting plate fixedly connected to the side wall of the second wire reel, a worm gear movably mounted on the side wall of the connecting plate, a lever fixedly connected to the side wall of the worm gear, and a plurality of worm gear teeth fixedly connected to the outer surface of the rotating disk, the worm gear teeth meshing with the worm gear.

[0006] Preferably, a motor is fixedly connected to the upper surface of the base plate, a gear is fixedly connected to the output end of the motor, an external gear ring is fixedly connected to the outer surface of the rotating shaft, the external gear ring meshes with the gear, and a bundler is fixedly connected to the upper surface of the base plate.

[0007] Preferably, the inner surface of the wire guide groove is provided with a first rotating groove, and there are two first rotating grooves. A first roller is movably installed on the inner wall of the first rotating groove.

[0008] Preferably, a fixed shaft is fixedly connected to the inner wall of the extrusion plate, and a second roller is sleeved on the outer surface of the fixed shaft.

[0009] Preferably, the end of the movable pin away from the extrusion plate is fixedly connected to a limiting plate, and the side wall of the limiting plate is in contact with the side wall of the rotating disk near the limiting plate.

[0010] Preferably, a support plate is fixedly connected to the upper surface of the base plate, and there are two support plates. A first sliding groove is formed on the outer surface of the first coil, and the support plate on the left side is located inside the first sliding groove.

[0011] Preferably, the outer surface of the second reel is provided with a second sliding groove, and the support plate on the right side is located inside the second sliding groove.

[0012] Preferably, the support plate has a second rotating groove inside, and there are multiple second rotating grooves. A third roller is movably installed on the inner wall of the second rotating groove.

[0013] This utility model provides a cable conductor stranding tension control device, which has the following beneficial effects:

[0014] Compared to existing technologies, this cable conductor stranding tension control device utilizes a lever, worm gear, worm wheel teeth, rotating disk, moving pin, inclined groove, rotating shaft, extrusion plate, and second roller. When it is necessary to increase the tension on the conductor, turning the lever drives the worm gear to rotate. Since the worm gear and worm wheel teeth mesh, they can drive the rotating disk to rotate. Because the moving pin is located inside the inclined groove, it can drive the adjacent moving pin to move closer to the rotating shaft, thus allowing the extrusion plate to move closer to the rotating shaft until the second roller contacts the conductor wire. At this point, continuing to move the second roller closer to the rotating shaft increases the conductor tension, and vice versa. Compared to existing tension control devices, which require a separate tension component (such as an independent magnetic powder brake) for each conductor and require manual calibration of each wire during debugging, making the operation cumbersome and prone to uneven conductor tension and loose structure due to parameter differences, this cable conductor stranding tension control device can achieve synchronous and precise control of the tension of multiple conductors by simply turning the lever, making the operation much simpler.

Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0026] Depend on Figures 1-9As shown, this utility model provides a cable conductor stranding tension control device, including a base plate 1, a rotating shaft 13 disposed above the base plate 1, a first wire reel 2 fixedly connected to the outer surface of the rotating shaft 13, a feeding roller 3 movably mounted on the side wall of the first wire reel 2, and multiple feeding rollers 3; a second wire reel 4 fixedly connected to the outer surface of the rotating shaft 13, a wire-passing groove 5 formed on the side wall of the second wire reel 4, and multiple wire-passing grooves 5; a rotating disk 6 movably mounted on the side wall of the second wire reel 4.

A pressing plate 7 is fixedly connected to the side wall of the movable pin 8. A connecting plate 16 is fixedly connected to the side wall of the second coil 4. A worm gear 17 is movably installed on the side wall of the connecting plate 16. A lever 18 is fixedly connected to the side wall of the worm gear 17. Multiple worm gear teeth 15 are fixedly connected to the outer surface of the rotating disk 6. The worm gear teeth 15 mesh with the worm gear 17. When it is necessary to increase the conductor load... When the tension is reached, turning the lever 18 drives the worm gear 17 to rotate. Since the worm gear 17 and the worm wheel teeth 15 mesh, the rotating disk 6 can be driven to rotate. Since the moving pin 8 is located inside the inclined groove 9, the adjacent moving pin 8 can be driven to move closer to the rotating shaft 13. Therefore, the extrusion plate 7 can be moved closer to the rotating shaft 13 until the second roller 22 contacts the conductor wire. At this time, continuing to move the second roller 22 closer to the rotating shaft 13 can increase the tension of the conductor, and vice versa, it will reduce the tension of the conductor. The upper surface of the base plate 1 is fixedly connected to the motor 11. The output end of the motor 11 is fixedly connected to the gear 12.

The bundler 10 is used to twist the conductors into a cable.

A fixed shaft 21 is fixedly connected to the inner wall of the extrusion plate 7. A second roller 22 is sleeved on the outer surface of the fixed shaft 21. The fixed shaft 21 can reduce the friction generated when the extrusion plate 7 contacts the conductor, reducing the occurrence of interference to the conductor caused by high temperatures generated by friction during stranding. A limiting plate 27 is fixedly connected to the end of the movable pin 8 away from the extrusion plate 7. The side wall of the limiting plate 27 is in contact with the side wall of the rotating disk 6 near the limiting plate 27. The limiting plate 27 can... The movement of the movable pin 8 is restricted. A support plate 23 is fixedly connected to the upper surface of the base plate 1. There are two support plates 23. The outer surface of the first wire reel 2 has a first sliding groove 24. The left support plate 23 is located inside the first sliding groove 24 and can support the first wire reel 2. The outer surface of the second wire reel 4 has a second sliding groove 28. The right support plate 23 is located inside the second sliding groove 28 and can support the second wire reel 4.
