Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of textile processing technology, and more specifically, to a cable-making device for wire and cable processing. Background Technology

[0002] Early cabling equipment was cumbersome and lacked precision when adjusting the position of components. Operators often had to spend a lot of time manually adjusting each component, making it difficult to quickly and accurately adapt to the cabling needs of different specifications of wires and cables. This resulted in low production efficiency and an inability to meet the ever-increasing order delivery speed. For example, when processing some special cables, the requirements for the angle and spacing of each core strand are extremely strict. Traditional equipment could hardly achieve the ideal process standards, resulting in a high product scrap rate.

[0003] In terms of limiting clamping, the clamping method of traditional equipment is relatively simple, using ordinary rollers or clamps. During the transmission of wires and cables, cable deviation, shaking, or even slippage can easily occur. This not only affects the stability and uniformity of the cable, but may also cause scratches on the cable surface, reducing the insulation performance and service life of the cable. Especially for some new cable materials with soft texture and smooth surface, traditional clamping methods are even more difficult to fix effectively.

[0004] The guiding and transmission structure also has defects. The design of the wire hole and wire groove is unreasonable, which makes the wires and cables easily encounter greater resistance when passing through, resulting in jamming. Moreover, when the position of the adjusting shuttle changes, it is not possible to ensure that the wires and cables are always on the right path, which often requires manual intervention and adjustment, further affecting the continuity of production and the degree of automation. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a cable-forming device for wire and cable processing, which solves the problem that the clamping method of traditional equipment is relatively simple, using ordinary rollers or clamps. During the transmission of wires and cables, cable deviation, shaking, or even slippage can easily occur. This not only affects the stability and uniformity of the cable formation, but may also cause scratches on the cable surface, reducing the insulation performance and service life of the cable. This is especially true for some new cable materials with soft texture and smooth surface, where traditional clamping methods are difficult to effectively fix.

[0006] According to one aspect, at least one embodiment of this disclosure provides a cable-forming apparatus for wire and cable processing, comprising: A placement tray, wherein an adjustment shuttle is provided on the placement tray; A position adjustment component, wherein the position adjustment component is disposed on the adjustment shuttle; A limiting clamping assembly is disposed on the side wall of the adjusting shuttle; The position adjustment assembly includes a drive shaft disposed on one side of the mounting plate. The side wall of the adjustment shuttle has an adjustment hole, and the drive shaft is inserted into the adjustment hole. The inner side wall of the adjustment hole is provided with a meshing thread, and the side wall of the drive shaft is provided with a turning thread. The meshing thread meshes with the turning thread. The side wall of the mounting plate is provided with a mounting shaft, and the end of the mounting shaft is provided with a fixing plate. The drive shaft has a rotation cavity inside, and the rotation cavity is fitted onto the fixing plate.

[0007] As a further technical solution, the side wall of the adjusting shuttle is provided with a linkage frame, and the number of linkage frames is several, with a rotating disc provided at the end of each linkage frame.

[0008] As a further technical solution, the limiting clamping assembly includes a limiting disk, which is disposed at the end of the adjusting shuttle. The side wall of the limiting disk has a clamping groove, and a rotating shaft is disposed inside the clamping groove. A clamping roller is fitted on the rotating shaft. There are two clamping rollers and two clamping rollers that are in contact with each other.

[0009] As a further technical solution, the mounting plate has a wire-passing hole, and the side wall of the adjusting shuttle is provided with a wire-passing mounting groove, with the wire-passing hole and the wire-passing mounting groove corresponding to each other.

[0010] As a further technical solution, the side wall of the adjusting shuttle is provided with a support frame, and the support frame is provided with a wire guide bracket, the wire guide bracket being positioned corresponding to the wire guide hole.

[0011] As a further technical solution, the adjusting shuttle has a conical structure, and the mounting plate is located at the end of the adjusting shuttle with a larger diameter.

[0012] As a further technical solution, the side wall of the mounting tray is provided with an expansion groove, which is connected to the wire hole.

[0013] As a further technical solution, the sidewall of the clamping roller is provided with an anti-slip pad, and the anti-slip pads between the two clamping rollers are in contact with each other.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the adjusting shuttle can be precisely moved axially along the drive shaft by rotating the rotating disc through the engagement threads and screw threads on the drive shaft and the adjusting shuttle. This design allows for quick and precise adjustment of the adjusting shuttle position according to the cabling requirements of different wires and cables, which is more efficient than manual adjustment in traditional equipment, improves production efficiency, and can meet the production requirements of various cable specifications. The limiting clamping is stable and reliable: the two clamping rollers in the limiting clamping assembly rotate through a self-rotating shaft, which can closely fit the wire and cable, limit its movement, and prevent the cable from shifting left or right during cabling. At the same time, the side walls of the clamping rollers are protected against... The sliding pad increases friction with the cable, preventing cable slippage and ensuring stability during transmission. This helps improve cabling quality and reduces cabling defects caused by cable misalignment or slippage. The smooth and unobstructed guiding transmission is achieved through the cooperation of the cable guide hole on the mounting plate, the cable guide slot on the adjusting shuttle, and the cable guide bracket. This provides a smooth guiding path for the wires and cables, ensuring that the cable remains on the correct path even if the adjusting shuttle position changes. This reduces resistance and jamming during cable transmission, promotes production continuity, and lowers the risk of equipment failure and product damage caused by cable jamming.

[0023] like Figures 1-3 As shown, it illustrates a cable-forming apparatus for wire and cable processing according to this disclosure, comprising: Placement tray 1, with an adjustment shuttle 2 installed on it; Position adjustment component 3 is mounted on adjustment shuttle 2; Limiting clamping component 4 is disposed on the side wall of adjusting shuttle 2; The position adjustment assembly 3 includes a drive shaft 3-1, which is located on one side of the mounting plate 1. The side wall of the adjustment shuttle 2 has an adjustment hole 3-2. The drive shaft 3-1 is inserted into the adjustment hole 3-2. The inner side wall of the adjustment hole 3-2 is provided with a meshing thread 3-3. The side wall of the drive shaft 3-1 is provided with a screw thread 3-4. The meshing thread 3-3 and the screw thread 3-4 mesh with each other. The side wall of the mounting plate 1 is provided with a mounting shaft 3-5. The end of the mounting shaft 3-5 is provided with a fixed plate 3-6. The inside of the drive shaft 3-1 is provided with a rotation cavity 3-7, which is fitted onto the fixed plate 3-6.

[0024] The limiting clamping assembly 4 includes a limiting disk 4-1, which is located at the end of the adjusting shuttle 2. The side wall of the limiting disk 4-1 has a clamping groove 4-2. A rotating shaft 4-3 is arranged inside the clamping groove 4-2. A clamping roller 4-4 is fitted on the rotating shaft 4-3. There are two clamping rollers 4-4 and two rotating shafts 4-3, and the two clamping rollers 4-4 are in contact with each other.

[0025] In some examples, the mounting plate 1 is first securely placed on a suitable working platform to ensure its stability and prevent displacement during cabling. The mounting plate 1 serves as the basic support component of the entire device, providing a foundation for the installation and operation of subsequent components. The adjusting shuttle 2 is then installed onto the mounting plate 1. The adjusting hole 3-2 on the adjusting shuttle 2 must be precisely aligned with the drive shaft 3-1 on one side of the mounting plate 1. The drive shaft 3-1 is slowly inserted into the adjusting hole 3-2. Because the inner wall of the adjusting hole 3-2 has a meshing thread 3-3, and the side wall of the drive shaft 3-1 has a turning thread 3-4, and the two mesh with each other, the rotation of the drive shaft 3-1 can drive the adjusting shuttle 2 to adjust its position along its axial direction. A fixed plate 3-6 is installed at the end of the mounting shaft 3-5 on the side wall of the mounting plate 1. The rotation cavity 3-7 inside the drive shaft 3-1 is fitted onto the fixed plate 3-6. This structural design ensures that the drive shaft 3-1 can rotate stably around the fixed plate 3-6 while driving the adjusting shuttle 2 to move, providing stable power transmission for subsequent cabling operations. A limiting plate 4-1 is installed at the end of the adjusting shuttle 2. A clamping groove 4-2 is opened on the side wall of the limiting plate 4-1. The rotating shaft 4-3 is installed inside the clamping groove 4-2. Then, a clamping roller 4-4 is fitted onto the rotating shaft 4-3. According to the design requirements, the two clamping rollers 4-4 are installed in the correct number and ensure that the two clamping rollers 4-4 fit tightly together.

[0026] When the wire and cable pass through the limiting clamping assembly 4, the two mating clamping rollers 4-4 can limit and clamp the wire and cable. On the one hand, it prevents the wire and cable from shifting left and right during the cabling process, ensuring the stability and accuracy of the cabling. On the other hand, the friction between the clamping rollers 4-4 and the wire and cable helps the wire and cable to be smoothly conveyed forward and participate in the cabling and stranding process.

[0027] like Figures 1-3 As shown in the figure, this embodiment proposes that the side wall of the adjusting shuttle 2 is provided with a linkage frame 3-8, the number of linkage frames 3-8 is several, and the ends of the multiple linkage frames 3-8 are provided with a rotating disc 3-9.

[0028] In some examples, a linkage frame 3-8 is installed on the side wall of the adjusting shuttle 2. The number of linkage frames 3-8 is set according to the actual operation convenience and adjustment accuracy requirements. A rotating disc 3-9 is uniformly installed at the end of these linkage frames 3-8. The operator can manually rotate the rotating disc 3-9 and use the linkage effect of the linkage frame 3-8 to drive the adjusting shuttle 2 to rotate synchronously. Because the adjusting shuttle 2 and the drive shaft 3-1 are engaged by a thread, the rotation of the adjusting shuttle 2 will be converted into its axial movement along the drive shaft 3-1, thereby realizing the precise adjustment of the position of the adjusting shuttle 2 to adapt to the position requirements of each component when different specifications of wires and cables are bundled.

[0029] For example, such as Figure 2 As shown, the mounting plate 1 has a wire hole 4-5, and the side wall of the adjusting shuttle 2 is provided with a wire insertion groove 4-6. The positions of the wire hole 4-5 and the wire insertion groove 4-6 are corresponding.

[0030] In some examples, wire-passing holes 4-5 are precisely drilled on the mounting plate 1 according to the design position, and wire-passing mounting grooves 4-6 are set on the side wall of the adjusting shuttle 2. The positions of the wire-passing holes 4-5 and the wire-passing mounting grooves 4-6 are strictly corresponding. The wires and cables first pass through the wire-passing holes 4-5 on the mounting plate 1, and then enter the wire-passing mounting grooves 4-6 on the side wall of the adjusting shuttle 2. The wire-passing holes 4-5 and the wire-passing mounting grooves 4-6 provide a preliminary guiding path for the wires and cables, enabling them to smoothly enter the subsequent processing components. They also limit the horizontal position of the wires and cables to a certain extent, preventing them from shaking significantly during equipment operation.

[0031] For example, such as Figure 1 As shown, the side wall of the adjusting shuttle 2 is provided with a support frame 4-7, and a wire guide bracket 4-8 is provided on the support frame 4-7. The wire guide bracket 4-8 corresponds to the position of the wire guide hole 4-5.

[0032] In some examples, a support frame 4-7 is installed on the side wall of the adjusting shuttle 2. The support frame 4-7 serves to support and fix the wire guide bracket 4-8. The wire guide bracket 4-8 is installed on the support frame 4-7, and its position is adjusted to correspond to the position of the wire guide hole 4-5 on the mounting plate 1. When the wire and cable pass through the wire guide hole 4-5, they will pass through the wire guide bracket 4-8. The wire guide bracket 4-8 further guides and supports the wire and cable. Especially when the position of the adjusting shuttle 2 changes, the wire guide bracket 4-8 can ensure that the wire and cable are always in the right position and smoothly enter the subsequent processing stage, reducing the cabling quality problems caused by the position deviation of the wire and cable.

[0033] For example, such as Figure 1 As shown, the adjusting shuttle 2 has a conical structure, and the mounting plate 1 is located at the end of the adjusting shuttle 2 with a larger diameter.

[0034] In some examples, the adjusting shuttle 2 is made with a conical structure according to the design requirements. During installation, the placement plate 1 is placed at the end of the adjusting shuttle 2 with a larger diameter. The conical structure of the adjusting shuttle 2 has unique advantages in the cabling process. As the adjusting shuttle 2 moves along the drive shaft 3-1, its different diameter positions can have a certain influence on the arrangement and twisting angle of the wires and cables. When processing wires and cables of different specifications, the position of the adjusting shuttle 2 can be adjusted to utilize its conical structure, so that the wires and cables can be better twisted during the cabling process, improving the tightness and uniformity of the cabling and meeting different cabling process requirements.

[0035] For example, such as Figure 2 As shown, the side wall of the mounting plate 1 is provided with an expansion groove 5, which is connected to the wire hole 4-5.

[0036] In some examples, an expansion slot 5 is provided on the side wall of the mounting tray 1, and the expansion slot 5 is connected to the cable passage hole 4-5. The presence of the expansion slot 5 provides more flexibility for the introduction and exit of wires and cables. In some special cabling processes, or when multiple wires and cables need to be processed at the same time, the wires and cables can be introduced into the cable passage hole 4-5 in a specific way through the expansion slot 5, which facilitates the grouping and management of wires and cables. It also helps to handle wires and cables more conveniently during equipment maintenance and debugging.

[0037] For example, such as Figure 3 As shown, anti-slip pads 6 are provided on the side walls of the clamping rollers 4-4, and the anti-slip pads 6 between the two clamping rollers 4-4 are in contact.

[0038] In some examples, anti-slip pads 6 are installed on the sidewalls of each clamping roller 4-4. After installation, ensure that the anti-slip pads 6 between the two clamping rollers 4-4 are in close contact with each other. The main function of the anti-slip pads 6 is to increase the friction between the clamping rollers 4-4 and the wires and cables. When the wires and cables are clamped between the two clamping rollers 4-4, the anti-slip pads 6 can effectively prevent the wires and cables from sliding on the surface of the clamping rollers 4-4, thereby ensuring that the wires and cables can be stably transported and stranded during the cabling process. The effect of the anti-slip pads 6 is more significant when dealing with wires and cables with relatively smooth surfaces or soft textures, which can greatly improve the quality and stability of the cabling.

[0039] When the equipment is started, the mounting plate 1 remains stationary as a basic support component. When the position of the adjusting shuttle 2 needs to be adjusted according to the specifications of the wires and cables, the operator rotates the rotating disc 3-9, which drives the adjusting shuttle 2 to rotate through the linkage frame 3-8. Since the meshing thread 3-3 on the inner side wall of the adjusting hole 3-2 of the adjusting shuttle 2 meshes with the rotating thread 3-4 on the side wall of the drive shaft 3-1, the rotation of the adjusting shuttle 2 is converted into axial movement along the drive shaft 3-1. At the same time, the rotation cavity 3-7 inside the drive shaft 3-1 is fitted onto the fixed disc 3-6. The fixed disc 3-6 is connected to the mounting plate 1 through the mounting shaft 3-5, ensuring that the drive shaft 3-1 can rotate stably around the fixed disc 3-6 when moving with the adjusting shuttle 2, providing stable power transmission and support for the position adjustment of the adjusting shuttle 2.

[0040] During the cabling process, the wires and cables pass sequentially through the wire-passing holes 4-5 of the mounting tray 1, the wire-passing mounting slots 4-6 of the adjusting shuttle 2, and the wire-passing brackets 4-8. The wire-passing holes 4-5 and the wire-passing mounting slots 4-6 correspond in position, providing initial guidance for the wires and cables and limiting their horizontal sway. The wire-passing brackets 4-8, supported by the support frame 4-7, further ensure that the wires and cables are on the appropriate path. Even if the position of the adjusting shuttle 2 changes, they can still stably enter the subsequent stages. The expansion slots 5 on the side wall of the mounting tray 1 are connected to the wire-passing holes 4-5, which can flexibly introduce multiple wires and cables or meet the wiring requirements of special processes, and facilitate group management.

[0041] When the wire and cable reach the limit clamping assembly 4, the two clamping rollers 4-4 on the limit plate 4-1 fit tightly together and rotate through the rotation shaft 4-3. The wire and cable pass between the two clamping rollers 4-4. Under the action of friction, the clamping rollers 4-4 rotate with the wire and cable, which can limit the movement and prevent left and right deviation, and also assist in the conveying. The anti-slip pads 6 on the side wall of the clamping rollers 4-4 increase the friction with the wire and cable, preventing the smooth surface or soft texture of the wire and cable from sliding and ensuring the stability of the transmission.

[0042] In addition, the adjusting shuttle 2, which has a conical structure, is connected to the mounting plate 1 at one end with a larger diameter. As the adjusting shuttle 2 moves along the drive shaft 3-1, the arrangement and twisting angle of the wires and cables are changed at different diameter positions. By adjusting the position of the adjusting shuttle 2, the conical structure is used to better twist the wires and cables of different specifications, improve the tightness and uniformity of the cabling, and finally complete the high-quality cabling process.
