Description

Technical Field

[0001] This utility model relates to the field of wire and cable manufacturing technology, and in particular to a cable armoring cabling device that prevents lateral displacement during twisting. Background Technology

[0002] The wire and cable manufacturing technology focuses on the design, processing, and equipment development of various wires and cables, covering conductor stranding, insulation coating, armor protection, and other aspects. It aims to improve the mechanical strength, environmental resistance, and conductivity of cables and cables, and is widely used in industries such as power transmission, communication networks, and rail transportation. It is a key technological support for ensuring energy and information transmission.

[0003] Cable armoring and cabling equipment is a specialized piece of equipment used for cable armoring and cabling processes. Its core function is to twist multiple insulated wire cores into a cable and wrap it with a metal armor layer (such as steel tape or steel wire). Through automated mechanisms, it achieves coordinated operations of processes such as wire feeding, twisting, armoring, and wire take-up. This not only enhances the cable's tensile and impact resistance but also improves cabling efficiency and precision, making it an important piece of equipment for achieving large-scale production of high-reliability cables.

[0004] However, in the existing technology, some cable armoring cabling devices are difficult to apply differentiated tension to wires with different tensions. As a result, slack wires often shift laterally during twisting due to insufficient tension, which leads to a decrease in the twisting accuracy of multiple wires. Furthermore, the tension cannot be adjusted in real time according to the wire parameters, which can easily cause wire deformation due to excessive pulling or affect the quality of cabling due to uneven tension.

[0005] Therefore, a cable armor cabling device to prevent lateral displacement during twisting is proposed to address the above problems. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a cable armoring cabling device to prevent lateral deviation during twisting. It aims to improve the problems in some existing cable armoring cabling devices that are difficult to apply differentiated tension to wires with different tensions, which can lead to easy deviation of slack wires, reduced twisting accuracy, difficulty in real-time tension adjustment, and resulting in wire deformation or poor cabling quality.

[0013] As a further description of the above technical solution:

[0014] A rotating roller is rotatably connected to the left side of the cable bundle tube, and the rotation direction of the rotating roller is consistent with the cable conveying direction.

[0015] As a further description of the above technical solution:

[0033] 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 protection scope of the present utility model.

[0034] Reference Figures 1 to 5 This utility model provides an embodiment of a cable armoring cabling device for preventing lateral displacement during twisting, comprising a support plate 1. The support plate 1 serves as the supporting foundation for the entire device, providing an installation carrier for each component. Multiple sliding grooves 2 are provided on both the left and right sides of the support plate 1 to provide sliding tracks for the cable bundles 8, ensuring that the cable bundles 8 can move stably along them and achieving synchronous adjustment of multiple cable bundles 8. The support plate 1 also has a cavity inside to accommodate internal components such as a motor 3 and a turntable 4, providing installation space for them. A motor 3 is fixedly connected to the right side of the inner wall of the support plate 1 to provide power output, driving the turntable 4 to rotate, providing a power basis for the coiling and adjustment of the cable bundles 8. The drive end of the motor 3 is fixedly connected to the turntable 4, which rotates under the drive of the motor 3, and transmits power to the slider 7 through a connecting rod 6, driving the slider 7 and the cable bundles 8 to move.

[0035] A support column 5 is fixedly connected to the left side of the turntable 4, providing radial support and ensuring the stability of the turntable 4 during rotation. The other end of the support column 5 is rotatably connected to the left side of the inner wall of the support plate 1, forming a stable connection between the support column 5 and the support plate 1, enhancing the stability of the turntable 4 during rotation. Multiple connecting rods 6 are rotatably connected to both sides of the turntable 4, connecting the turntable 4 and the slider 7, converting the rotational motion of the turntable 4 into the linear motion of the slider 7, thus transmitting force. The other end of the connecting rod 6 is rotatably connected to the slider 7. Driven by the connecting rods 6 and the slider 7... The cable bundle tube 8 slides along the inner wall of the slide groove 2, allowing the position of the cable bundle tube 8 to be adjusted. The inner wall of the slider 7 is fixedly connected to the cable bundle tube 8, which slides inside the slide groove 2, providing a passage for the wires to pass through. Differential tension is applied to wires with different tensions, so that slack wires are tightened and qualified wires are kept under appropriate tension, ensuring that the tension of the wires is balanced before twisting and avoiding lateral deviation. The inside of the cable bundle tube 8 is detachably connected to a rubber tube 9 made of elastic material, which can buffer the friction and compression during wire transportation, prevent damage to the outer insulation layer of the wires, and is detachable for easy replacement.

[0036] Multiple limiting strips 10, which slide against the inner wall of the cable bundle tube 8, are externally fixed to the rubber tube 9, stably restricting the rubber tube 9 within the cable bundle tube 8 to prevent it from shaking or shifting, ensuring stable protection. A rotating roller 11, made of highly wear-resistant material, is rotatably connected to the left side of the cable bundle tube 8. The roller guides the wire feeding through its arc-shaped surface, preventing wear between the wire and the opening of the cable bundle tube 8. The rotating roller 11 rotates in the same direction as the cable feeding, rotating synchronously with the wire feeding. A threaded sleeve 12 is threadedly connected to the right side of the cable bundle tube 8, fixing the position of the rubber tube 9 through the threaded connection to prevent it from falling off. It can also be easily replaced after being unscrewed. The inner wall of the threaded sleeve 12 covers the right end of the rubber tube 9, enhancing the fixing effect and ensuring the rubber tube 9 is securely installed. A supporting sliding component is installed at the bottom of the support plate 1 to support the support plate 1 and adjust its position along the axial direction, ensuring accurate wire feeding path.

[0037] The supporting sliding assembly includes a base 13 with a support plate 1 fixed at its top and a bottom end slidably connected to a slide rail 14. This allows the support plate 1 to move with the slide rail 14, thus adjusting its position. The top end of the base 13 is fixedly connected to the bottom end of the support plate 1, forming a stable connection and ensuring the support plate 1 moves synchronously with the base 13. The bottom end of the base 13 is slidably connected to the slide rail 14, providing a sliding track for the base 13. This, combined with a lead screw drive, enables fine-tuning of the support plate 1 along its axial direction, ensuring the optimal incident angle when the wire enters the stranding assembly. The bottom end of the slide rail 14 is fixedly connected to... The base plate 15 serves as the bottom support structure of the entire device, providing a stable installation platform for the slide rail 14, armoring machine 19, stranding assembly, etc. The top center of the supporting slide assembly is equipped with a stranding assembly for stranding multiple wires after tension adjustment, ensuring precise stranding. The stranding assembly includes a support plate 16 to provide installation support for the wire harness ring 17 and the micro motor, ensuring the structural stability of the stranding assembly. The bottom end of the support plate 16 is fixedly connected to the top center of the base plate 15, forming a stable connection between the support plate 16 and the base plate 15, providing a stable support foundation for the stranding assembly.

[0038] A wire harness ring 17 is rotatably connected to the top of the support plate 16 for twisting the wires, allowing multiple wires to be twisted together under its rotation. A micro motor is installed inside the support plate 16 to provide power, driving the wire harness ring 17 to rotate around the cable conveying direction, thus providing power for the wire twisting. The drive end of the micro motor is fixedly connected to the bottom of the wire harness ring 17, enabling the wire harness ring 17 to rotate around the cable conveying direction as an axis, achieving power transmission between the micro motor and the wire harness ring 17. This ensures that the wire harness ring 17 can rotate stably to complete the twisting operation. The internal moving connection of 17 has multiple ball bearings 18 that reduce friction between the wire and the wire harness 17 through their omnidirectional rolling characteristics, helping the wire to keep the axis of alignment during twisting and reducing the risk of lateral displacement. An armoring machine 19 is installed on the top left of the supporting sliding assembly to armor the twisted cable, improve the cable's compressive strength and structural stability, and suppress the release of internal twisting stress. The bottom end of the armoring machine 19 is fixedly connected to the top left of the base plate 15, so that the armoring machine 19 and the base plate 15 form a stable connection, ensuring the accuracy and quality of the armoring process.

[0039] Working principle: Multiple wires first pass through the rubber tube 9 inside the wire harness tube 8. The rubber tube 9 is stably embedded in the wire harness tube 8 by the limiting strip 10. Its elastic material can buffer the friction and compression during wire transport and prevent damage to the insulation layer. At this time, the threaded sleeve 12 on the right side of the wire harness tube 8 tightly covers the right end of the rubber tube 9, fixing the position of the rubber tube 9.

[0040] To address the lateral shift issue caused by differences in the tension of different wires, the device employs a motor 3 within the support plate 1 for precise adjustment. After the motor 3 starts, the turntable 4 rotates stably under the radial support of the support column 5. This rotation, via the connecting rod 6 and the slider 7, drives the wire bundle tube 8 to converge synchronously towards the center along the slide groove 2, applying differentiated tension to multiple wires. For slack wires with insufficient tension, the wire bundle tube 8 increases its convergence range to enhance the pulling force, while maintaining appropriate tension for wires with adequate tension. This dynamic adjustment ensures that all wires are in a state of balanced tension before entering the stranding process, fundamentally eliminating the potential for lateral shift caused by localized slack. This process can be adjusted in real-time based on parameters such as the wire's flexibility, diameter, and initial tension, preventing excessive pulling that could lead to wire deformation. Furthermore, the symmetrical distribution of multiple sets of wire bundle tubes 8 further ensures uniform force distribution on the wires.

[0041] After being guided by the rotating roller 11 on the left side of the wire bundle tube 8, the wire enters the next process. The rotating roller 11 is made of high wear-resistant polyurethane material, and its rotation direction is completely synchronized with the wire conveying direction. The arc-shaped roller surface prevents the wire from wearing with the opening of the wire bundle tube 8.

[0042] The wires then enter the stranding assembly. The micro motor inside the support plate 16 uses servo drive technology to adjust the rotation speed of the wire loop 17 in real time according to the wire material. Combined with the omnidirectional rolling characteristics of the ball bearings 18 inside the loop, the multiple wires always keep their axes aligned during stranding, significantly reducing the risk of lateral deviation. During the stranding process, the slide rail 14 at the top of the base plate 15 plays a crucial role—it adopts a high-precision linear guide structure, which, together with the lead screw drive at the bottom of the base 13, allows for fine adjustment of the support plate 1 along the axial direction. This ensures that the incident angle of the wires entering the stranding assembly is always optimal, perfectly matching the rotation trajectory of the wire loop 17, further consolidating the anti-deviation effect after tension adjustment.

[0043] The stranded cable then enters the armoring machine 19, which employs a dual-station steel strip armoring structure. A servo motor drives the feed rollers and forming mold to work in tandem, automatically adjusting the steel strip tension and winding angle according to the cable diameter. During the armoring process, the armoring machine 19 and the stranding assembly are linked by a PLC control system to ensure that the steel strip winding pitch error is kept within a minimal range. The resulting armor layer not only improves compressive strength but also further suppresses the release of stranding stress within the cable through a tightly fitted armor structure, preventing loosening or shifting during later use.

[0044] When the rubber tube 9 wears out due to long-term use, simply unscrew the threaded sleeve 12 to pull out the old rubber tube 9 along the inner wall of the cable tie tube 8, replace it with a new part, and then tighten the threaded sleeve 12 again to complete the maintenance. The whole process does not require special tools and can be completed quickly by a single person, which significantly improves the maintenance efficiency of the equipment.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
