Description

Technical Field

[0001] This invention relates to the field of cable manufacturing technology, specifically to a cable stabilizer that prevents cable scratches. Background Technology

[0002] During cable winding, the incoming cable may sway, so a cable stabilizer is needed to keep it stable to ensure stable winding later.

[0003] Patent application number 202321212192.3 discloses a cable forming and stabilizing device for a cable forming machine. This device uses stabilizing rollers on both sides inside a guide frame. When cable bundles of different specifications pass through the stabilizing rollers, a fixed clamp and a movable block compress a spring. The reaction force of the compressed spring pushes the fixed clamp through the movable block, thus causing the fixed clamp to drive the stabilizing rollers to limit and stabilize the cable bundles of different specifications. However, for cables with larger diameters, a single guide roller is not well-suited and can easily lead to issues such as... Figure 13 The condition shown indicates that the cable's sheath is easily scratched during stable cable transmission, ultimately affecting the cable's quality. Summary of the Invention

Detailed Implementation

[0038] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0039] Example 1

[0040] Traditional cable stabilization devices are difficult to adapt to the stable transmission of cables of various sizes. Due to unsuitable dimensions, they may scratch the cable sheath, affecting the normal use of the cable. For details, please refer to... Figure 13 When the cable cross-sectional diameter is larger than the concave area of ​​the guide roller, the contact area between the edge of the concave area and the cable sheath is small, making it easy to scratch during transport. This embodiment provides a cable stabilizer to prevent cable scratches, such as... Figures 1-8 As shown, the system includes a base 1, on which at least two sets of lifting mechanisms 2 are installed. A housing 3, a through rectangular shell, is mounted on each lifting mechanism 2 for cable passage. Two sets of conversion mechanisms 4 are symmetrically arranged inside the housing 3. Adjusting the conversion mechanisms 4 allows for the stable transport of cables of various sizes. Based on the cable size, the conversion mechanisms 4 can be adjusted in advance to fit the required cable size before the cable is wound up. This effectively avoids scratches on the cable sheath caused by contact between the recessed edge and the cable sheath, better meeting actual production needs.

[0041] To better adapt the rotating roller 44 to the cable, a conversion mechanism 4 is provided, including a housing 41. A power mechanism 6 is mounted on the housing 41 to drive the connecting shaft 45 to rotate and change the position of the rotating roller 44. A notch a is provided on the housing 41 corresponding to the position of the power mechanism 6, facilitating manual operation of the worm gear 63. The connecting shaft 45 is rotatably mounted inside the housing 41, and a top plate 42 and a bottom plate 43 are sequentially fixed to the connecting shaft 45. Several sets of rotating rollers 44 are rotatably mounted between the top plate 42 and the bottom plate 43, centered on the connecting shaft 45. These sets of rotating rollers 44 are arranged in a circular pattern, and the degree of surface concavity varies among the sets. The edges of the concave areas on the rotating roller 44 are designed with arc-shaped surfaces 46 to prevent scratching the cable surface. The height and depth of the recesses on different rollers 44 are different, which can better adapt to cables of different thicknesses, ensure the stable conveying of cables of corresponding sizes, and avoid the situation of scratching the cables due to size mismatch, thus better meeting the actual production needs. In actual use, controlling the power mechanism 6 can drive the connecting shaft 45 to rotate, thereby driving the top plate 42 and the bottom plate 43 to rotate simultaneously, so that several sets of rollers 44 rotate until the corresponding roller 44 rotates to the appropriate position.

[0042] Specifically, the power mechanism 6 includes a protective shell 61 fixed to the housing 41, and a worm gear 62 sleeved on the connecting shaft 45. A worm 63, rotatably mounted to the protective shell 61, meshes with the worm gear 62, with its end extending out of the protective shell 61. When the position of the rotating roller 44 needs to be changed, the operator can manually rotate the worm 63, causing the meshing worm gear 62 to rotate, which in turn rotates the connecting shaft 45, causing several sets of rotating rollers 44 to rotate until the corresponding roller 44 reaches the appropriate position. The overall structure is simple and easy to operate.

[0043] Taking stable cable winding as an example, the height of the winding frame varies. During the winding process, ensuring that the output cable is approximately at the same height as the winding end of the winding frame ensures more stable cable winding. To this end, the lifting mechanism 2 includes a support sleeve 21 fixed to the base 1. A hydraulic rod 22 is installed inside the support sleeve 21. A sliding sleeve 23, fixed to the housing 3, is installed at the movable end of the hydraulic rod 22 and fits onto the surface of the support sleeve 21. Depending on the height of the winding end of the winding frame, the hydraulic rod 22 is activated. Through the extension and retraction of the hydraulic rod 22, the sliding sleeve 23 rises or falls, ensuring that the output cable is approximately at the same height as the winding end, thus improving the stability of cable delivery and winding.

[0044] Due to variations in cable production lines, the sway amplitude of cables entering the cable stabilizer also differs. An adjustment mechanism 5 is installed on the housing 3 to regulate the cable tension caused by the two sets of conversion mechanisms 4. The adjustment mechanism 5 includes a screw 54 threaded onto the housing 3 and guide rods 55 fixed to the housing 41 and slidably mounted on the housing 3. Two sets of guide rods 55 are provided, located on either side of the screw 54. The end of the anti-deviation rod 52 facing away from the housing 41 does not extend into the cylinder 51. The cylinder 51 is rotatably mounted at the end of the screw 54. By rotating the screw 54, the cylinder 51 can be moved under the constraint of the guide rods 55. A spring 53 is fixed between the cylinder 51 and the housing 41. An anti-deviation rod 52 is fixed at the position on the housing 41 corresponding to the spring 53 to prevent the spring 53 from deviating from its original position. The anti-deviation rod 52 is located inside the spring 53. Here, we take a cable with a large sway amplitude being conveyed as an example. To reduce this oscillation amplitude, the squeezing force of the rotating roller 44 on the cable must be increased. The following is an example of increasing this squeezing force:

[0045] Rotating the screw 54 causes the cylinder 51 to move inward, which in turn causes the conversion mechanism 4 to move inward, continuously clamping the cable. The spring 53 is also continuously compressed, increasing the squeezing force on the cable, reducing its swing amplitude, and ensuring stable cable transmission, but it will increase the wear on the cable surface.

[0046] For cables with small swing amplitude entering the cable stabilizer, the screw 54 can be rotated in the opposite direction to reduce the squeezing force on the cable and reduce wear on the cable surface.

[0047] Example 2

[0048] refer to Figures 9-10 The method is basically the same as in Embodiment 1, except that the power mechanism 7 includes a reducer 72 mounted on the connecting shaft 45, and a motor 71 mounted on the reducer 72. The motor 71 drives the connecting shaft 45 to rotate through the reducer 72. Starting the motor 71 drives the connecting shaft 45 to rotate through the reducer 72, which in turn drives the rotating roller 44 in the conversion mechanism 4 to rotate and adjust its position. Compared to Embodiment 1, the use of electrified operation can reduce the workload of the staff and simplify the operation, but it increases the cost.

[0049] Example 3

[0050] refer to Figures 11-12The method is basically the same as in Embodiment 1, except that: the power mechanism 8 includes an elastic telescopic rod 81 fixed to the end of the connecting shaft 45, a rotating plate 82 is fixed to the end of the elastic telescopic rod 81 away from the connecting shaft 45, and a locking rod 83 is fixed on the rotating plate 82. The locking rod 83 is a columnar rod, and the top of the housing 41 has several sets of locking slots 84 that cooperate with the locking rod 83. The locking slots 84 are columnar slots. The housing 3 has an opening b corresponding to the position of the power mechanism 8, which is convenient for manual adjustment by the operator. When it is necessary to adjust the position of the rotating roller 44 in the conversion mechanism 4, the rotating plate 82 is lifted upward, so that the locking rod 83 moves upward and disengages from the locking slot 84. Then the rotating plate 82 can be rotated, thereby driving the connecting shaft 45 to rotate, thereby driving the rotating roller 44 to rotate to the appropriate position. Then, the operator slowly releases the lever, and under the elastic force of the elastic telescopic rod 81, the locking rod 83 moves downward and engages in the corresponding locking slot 84, thereby realizing the adjustment of the position of the rotating roller 44.
