Description

Technical Field

[0001] This utility model relates to the field of cable production technology, specifically a steel strip armoring machine. Background Technology

[0002] In the field of wire and cable manufacturing, steel tape armoring is a key process that enhances the mechanical protection properties of cables, such as resistance to pressure, impact, and rodent bites. Traditional steel tape armoring equipment generally suffers from low automation and poor coordination between various process steps.

[0003] Specifically, firstly, in the steel strip wrapping process, most existing equipment uses fixed unwinding reels, requiring machine shutdown when changing steel strip coils, which severely impacts production efficiency and continuity. Secondly, traditional guiding and bending mechanisms are inconvenient to adjust, making it difficult to ensure the steel strip is always tightly wrapped around the cable with constant tension and a predetermined spiral angle, easily leading to quality defects such as loose armor layers, curling edges, or uneven overlap.

[0004] Secondly, in the post-wrapping processing, traditional processes typically treat heating and softening as separate steps, resulting in excessively long production lines and cumbersome equipment layouts. After wrapping, the seams of the steel strip need to be welded to form a closed armor layer, but existing welding methods mostly rely on manual operation or simple spot welding, making it impossible to achieve automatic tracking and precise welding of the weld seams during continuous cable movement. This not only leads to poor weld quality stability and dependence on operator experience, but also presents efficiency bottlenecks and safety risks.

[0005] Furthermore, the entire system lacks integrated intelligent control. Key parameters such as cable conveying tension, steel strip wrapping status, and weld location identification are isolated from each other, making real-time data interaction and coordinated adjustment impossible. This results in poor equipment adaptability to different cable specifications, cumbersome process parameter adjustments, and difficulty in achieving high-quality, integrated, continuous, and stable production. In view of this, in-depth research was conducted to address the above problems, leading to this case. Utility Model Content

[0012] Beneficial effects

[0013] This utility model provides a steel strip armoring machine.

[0017] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0019] Example

[0020] Please see Figure 1-2In the field of wire and cable manufacturing, traditional steel strip armoring equipment generally suffers from low automation and poor coordination among various processes. On the one hand, fixed unwinding reels require machine downtime for changing reels, severely restricting production efficiency. Furthermore, traditional guiding mechanisms cannot ensure that the steel strip tightly wraps the cable with constant tension and precise angle, easily leading to quality defects such as loose armor layers and warping. On the other hand, post-wrapping heating and softening and welding are mostly independent processes, resulting in excessively long production lines. Existing welding methods mostly rely on manual or fixed-point welding, making it impossible to achieve automatic weld tracking and precise welding in continuous production, resulting in poor quality stability. In addition, the entire system lacks integrated intelligent control. Parameters such as cable tension, wrapping status, and weld recognition are isolated and cannot be adjusted collaboratively, leading to poor equipment adaptability, cumbersome parameter adjustments, and difficulty in achieving high-quality, high-efficiency, continuous, and stable production.

[0021] Therefore, this application protects a steel strip armoring machine, which guides the cable to the inside of the limiting shaft tube 2, and drives the angle drive motor 16 on the processing bracket 1 to drive the angle bevel gear set 4 on the drive end of the angle drive motor 16. The angle bevel gear set 4 drives the sleeve shaft tube 3 on it, which drives the angle horizontal ring 5 on it. The angle horizontal ring 5 drives the multiple material troughs 6 on it. The replaceable hydraulic chuck 7 inside the multiple material troughs 6 and the material shaft cylinder on it rotate stably. At the same time, through the cooperation of the bending pulley group 8 and the packaging pulley group 9, the steel strip is rotated and wrapped around the wire, thereby wrapping the wire. After the steel strip is wrapped, it is guided to the electric heating sleeve 1. Inside the 0, the heating and softening are achieved by the coiled electric heating rod 11. At the same time, the angle drive motor 16 runs, driving the variable frequency gear set 18 inside the angle gear 15 box on the drive end of the angle drive motor 16. The variable frequency gear set 18 drives the angle gear 15 on the output end. The angle gear 15 drives the set ring rack 14 that meshes with the gear. The set ring rack 14 rotates stably along the convex ring slider 13, so that the convex ring slider 13 rotates stably along the inner side of the concave arc slide 12. The convex ring block drives the electric welder on it. The scanning camera on the processing bracket 1 scans the valve core of the steel strip. The rotating electric welder performs spot welding on the cable steel strip.

[0022] In summary, the cable, guided by the cable collector, is stably conveyed through the center of the limiting shaft tube 2. During this process, a non-contact diameter gauge inside the limiting shaft tube 2 monitors the cable's outer diameter in real time, while a tension sensor on the cable collector simultaneously monitors the conveying tension. Subsequently, the angle drive motor 16 on the processing bracket 1 starts, driving the sleeve shaft tube 3 and the angle horizontal ring 5 fixed thereon to rotate via the angle bevel gear set 4. Multiple raw material shafts mounted on the ring (quickly fixed by the automatic centering jaws of the replaceable hydraulic chuck 7) rotate accordingly, releasing the steel strip. The steel strip passes through the adjustable bending pulley set 8 and packaging pulley set 9 on the angle horizontal ring 5, and is precisely rotated and wrapped around the cable to form an armor layer. The wrapped steel strip armored cable is introduced into the electric heating sleeve 10, where it is heated and softened by the coiled electric heating rod 11 under the precise management of the temperature control module to enhance its ductility and weldability. Next, another angle drive motor 16 on the electric heating sleeve 10 starts, driving the angle gear 15 through the frequency conversion gear set 18 in the angle gear 15 box. This drives the meshing sleeve ring rack 14 and convex ring slider 13, causing the welder mounted on it to rotate stably around the cable along the concave arc slide 12. At the same time, the scanning camera on the processing bracket 1 captures the image of the steel strip weld in real time and feeds it back to the central control system. This system processes multi-source data from the diameter gauge, tension sensor and camera, dynamically adjusts the speed of the angle drive motor 16 and the start and stop of the welder and welding parameters, and finally realizes fully automatic, adaptive closed-loop control of the entire armoring process - from cable introduction, steel strip wrapping, heating and softening to weld tracking and precise welding, ensuring high-efficiency and high-stability production.
