Description

Technical Field

[0001] This utility model relates to the field of cable stranding technology, specifically to a cable stranding device. Background Technology

[0002] Most power cables consist of three parts: a conductor, an insulator, and an outer protective layer. Cables, also known as copper cables, are cables that use copper conductors as the information transmission medium. During cable production, multiple sets of copper conductors are typically twisted together to allow for the transmission of larger amounts of data. This twisting process also makes the cable more flexible and gives it strong tensile strength. When twisting waterproof composite cables, multiple sets of conductors are usually placed on a twisting machine and wound together. However, the twisting process can easily damage the surface of the copper conductors, affecting the cable's performance in the long run.

[0003] According to CN219303397U, a cable stranding device includes a workbench with a support fixedly connected to its center. Multiple sets of supports are provided in the center of the workbench. A first rotating plate is rotatably connected to the end of the support. A second rotating plate is rotatably connected to the end of the support. A stranding cylinder is rotatably connected to the end of the support. A conductor limiting hole is formed in the center of the first rotating plate. Multiple sets of conductor limiting holes are provided in the center of the first rotating plate. This device applies lubricating oil to the cable before stranding via the second rotating plate. By applying lubricating oil to the surface of the conductor, it reduces the possibility of external breakage of the conductor during stranding, thereby minimizing the impact on subsequent data transmission.

[0004] Although the aforementioned patent can protect the cable and reduce the impact on subsequent data transmission, some lubricant may spill out through the oil outlet during the application of lubricant, resulting in material waste. This is because the cable stranding process can also cause wear on the formed lubricant film, which will affect the subsequent data transmission of the cable. Utility Model Content

[0005] The purpose of this invention is to provide a cable stranding device to solve the problem mentioned in the background art where lubricating oil is spilled out through the oil outlet during the application of lubricating oil, resulting in material waste. This is because the cable stranding process also causes wear on the formed lubricating oil film, which in turn affects the subsequent data transmission of the cable.

[0006] To achieve the above objectives, this utility model provides the following technical solution: it includes a workbench and five supports fixedly mounted on the workbench. One of the supports is equipped with a transmission component. The transmission component includes a motor fixedly mounted on the support and a fixing plate fixedly mounted on the support. A first wheel is fixedly mounted on the output end of the motor. A first wheel and a second wheel are rotatably mounted on the upper and lower parts of the fixing plate. A gearbox is provided between the first wheel and the second wheel. Both of the supports are equipped with an oiling component for applying lubricating oil to the twisted cable.

[0007] Preferably, the oiling assembly includes a fixed rod fixedly mounted on a bracket and two support rods fixedly mounted on the bracket. A rotating shaft is rotatably mounted on the fixed rod, and a belt is provided between the rotating shaft and the second wheel. A gear is fixedly mounted on the axial side wall of the rotating shaft. An oil reservoir is fixedly mounted on both support rods. A plurality of oil outlet pipes are fixedly mounted on the axial side wall inside the oil reservoir. A plurality of sponges are provided inside the plurality of oil outlet pipes. A fixed cylinder is fixedly mounted on the axial side wall of the oil reservoir. A limit plate is fixedly mounted inside the fixed cylinder, and a trapezoidal block is slidably mounted thereon. The gear and the trapezoidal block are in contact during movement, and the trapezoidal block meshes with the gear. A spring is fixedly mounted between the trapezoidal block and the limit plate. An oil brushing assembly is provided on the side wall of the trapezoidal block.

[0008] Preferably, the brushing assembly includes square plates fixedly installed on both sides of the trapezoidal block, a limiting shaft rotatably installed between the two square plates, a strip block rotatably installed on the side wall of the limiting shaft, a sliding cylinder slidably installed at one end of the strip block, and a plurality of goat hairs fixedly installed on the inner wall of the sliding cylinder, wherein a twisted wire assembly is commonly provided on three of the brackets.

[0009] Preferably, the stranded wire assembly includes a sleeve fixedly mounted on two supports and a first and second rotating wheel rotatably mounted on the sleeve. A stranded wire box is fixedly mounted on the supports. The first rotating wheel has several wire-passing holes, and the second rotating wheel has several limiting holes.

[0010] Preferably, the gear teeth are located at the upper end of the trapezoidal block, and the diameter of the limiting plate is much smaller than the diameter of the fixed cylinder.

[0011] Preferably, the strip block, trapezoidal block, and sliding cylinder have a certain angular gap.

[0012] Preferably, the gap between the first wheel and the second wheel is exactly the thickness of the cable after it is twisted.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The cable is twisted together by the cooperation of the first rotating wheel, the second rotating wheel, and the twisted box. The rotating shaft and gears are driven to rotate clockwise by the motor, gearbox, second wheel and belt. With the cooperation of gear, trapezoidal block and oil reservoir, gas is compressed into the oil reservoir, and the lubricating oil is squeezed into the oil outlet pipe to wet the sponge. When the cable moves, the cable will squeeze the sponge, thus applying the lubricating oil to the surface of the cable. This not only reduces the impact on data transmission of the twisted cable, but also saves material waste by using sponge material.

[0015] 2. Under the action of gears, trapezoidal blocks and strip blocks, the sliding cylinder moves along the direction of the cable. The goat hair inside the sliding cylinder will scrape the lubricating oil on the surface of the cable, spreading the lubricating oil evenly around the cable, further protecting the cable.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1-3 The system includes a workbench 1 and five supports 11 fixedly mounted on the workbench 1. One of the supports 11 is equipped with a transmission assembly 3. The transmission assembly 3 includes a motor 31 fixedly mounted on the support 11 and a fixing plate 32 fixedly mounted on the support 11. A first wheel 33 is fixedly mounted on the output end of the motor 31. The fixing plate 32 is rotatably mounted with the first wheel 33 and the second wheel 35. A gearbox 34 is provided between the first wheel 33 and the second wheel 35. The model of the gearbox 34 is b2dh05. Both supports 11 are equipped with an oiling assembly 4 for applying lubricating oil to the twisted cable.

[0023] The oiling assembly 4 includes a fixed rod 41 fixedly mounted on a bracket 11 and two support rods 44 fixedly mounted on the bracket 11. A rotating shaft 42 is rotatably mounted on the fixed rod 41. A belt 43 is provided between the rotating shaft 42 and the second wheel 35. A gear 47 is fixedly mounted on the axial side wall of the rotating shaft 42. An oil reservoir 45 is fixedly mounted on both support rods 44. Several oil outlet pipes 46 are fixedly mounted on the axial side wall inside the oil reservoir 45. Several sponges 403 are arranged inside the oil outlet pipes 46. A fixed cylinder 49 is fixedly installed on the axial side wall of the oil reservoir 45. A limit plate 402 is fixedly installed inside the fixed cylinder 49 and a trapezoidal block 48 is slidably installed. The gear 47 and the trapezoidal block 48 are in contact during movement, and the trapezoidal block 48 meshes with the gear 47. A spring 401 is fixedly installed between the trapezoidal block 48 and the limit plate 402. An oil brushing assembly 5 is provided on the side wall of the trapezoidal block 48. The sponge 403 can effectively prevent lubricating oil from leaking out through the oil outlet pipe 46 without pressure, reducing material waste.

[0024] The stranded wire assembly 2 includes a sleeve 24 fixedly mounted on two brackets 11 and a first rotating wheel 21 and a second rotating wheel 22 rotatably mounted on the sleeve 24. A stranded wire box 23 is fixedly mounted on the brackets 11. The first rotating wheel 21 has several wire-passing holes 25 and the second rotating wheel 22 has several limiting holes 26.

[0025] The tooth block of gear 47 is located at the upper end of trapezoidal block 48. Trapezoidal block 48 meshes with gear 47. At the same time as contact, downward pressure is applied to trapezoidal block 48. The diameter of limiting plate 402 is much smaller than the diameter of fixed cylinder 49, which can ensure that enough gas is compressed into oil reservoir 45 and sufficient pressure is applied to lubricating oil.

[0026] The gap between the first wheel 33 and the second wheel 35 is exactly the thickness of the twisted cable, so that the cable can be pulled out by friction.

[0027] In this embodiment: the cable is placed inside the sleeve 24, and several copper wires are passed through the first rotating wheel 21 and the second rotating wheel 22 and twisted around the cable in the twisted wire box 23. Lubricating oil is poured into the oil reservoir 45 through the oil inlet hole. The motor 31 is turned on, and the output end of the motor 31 drives the gearbox 34 to start running. The gearbox 34 drives the first wheel 33 to rotate counterclockwise and drives the second wheel 35 to rotate clockwise, thereby dragging the twisted cable. The second wheel 35 drives the rotating shaft 42 and the gear 47 to rotate clockwise through the belt 43. When the teeth on the gear 47 rotate, they rotate on the trapezoidal block 48. The striking action causes the trapezoidal block 48 to slide within the fixed cylinder 49, compressing the spring 401. This compresses the air inside the fixed cylinder 49, which then enters the oil reservoir 45. The air compresses the lubricating oil within the oil reservoir 45, causing it to pass through the oil outlet pipe 46 and wet the sponge 403. As the cable moves, it comes into contact with and is compressed by the sponge 403, thus applying the lubricating oil to the stranded cable. When the gear 47 moves away from the trapezoidal block 48, the spring 401 returns the trapezoidal block 48 to its original shape. Repeated operation effectively applies the lubricating oil to the cable, reducing the impact on data transmission in the stranded cable and saving material waste by using the sponge 403 material.

[0028] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figures 3-4 The brushing assembly 5 includes square plates 51 fixedly installed on both sides of the trapezoidal block 48. A limiting shaft 52 is rotatably installed between the two square plates 51. A strip block 53 is rotatably installed on the side wall of the limiting shaft 52. A sliding cylinder 54 is slidably installed at one end of the strip block 53. Several goat hairs 55 are fixedly installed on the inner wall of the sliding cylinder 54. A stranded wire assembly 2 is provided on the three brackets 11.

[0029] The strip block 53 has a certain angular gap with the trapezoidal block 48 and the sliding cylinder 54 to ensure that the strip block 53 will not come into contact with the trapezoidal block 48 and the sliding cylinder 54 during the movement.

[0030] In this embodiment: During the rotation of gear 47, a downward force is applied to trapezoidal block 48, causing trapezoidal block 48 to drive strip block 53 to move downward. Since strip block 53, trapezoidal block 48, and sliding cylinder 54 are all rotatably connected, strip block 53 will drive sliding cylinder 54 to move along the cable in the direction of arrow 1. After the force is released, strip block 53 will move upward with trapezoidal block 48, thereby driving sliding cylinder 54 to move in the direction of arrow 2. There are several goat hairs 55 inside sliding cylinder 54. The goat hairs 55 will rub against the cable, spreading the uneven lubricating oil evenly, so that the twisted cable is evenly coated with lubricating oil.
