AI Technical Summary
The existing cable wrapping process suffers from unstable tension control, which leads to easy deformation and unstable concentricity of the wrapping tape, affecting cable performance.
A novel device is designed that integrates the tension control structure with the film release structure. It uses a hysteresis brake and a magnetic suction component to control the tape tension and generates braking force through magnetic attraction to stabilize the tape release tension.
This improved the stability of the tape tension, thereby enhancing the cable processing quality and product yield.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cable manufacturing technology, specifically relating to a novel device for controlling the tension of cable winding tape. Background Technology
[0002] Currently, in the power and signal cable processing industry, the wrapping process involves a different structure for the tape release and the tape winding. Instead, tension is transmitted to the tape shaft via a pulley for relative control. Due to numerous influencing variables during machine operation and the time lag required for electrical feedback, the tape tension control during production is consistently lagging, resulting in unstable tape tension, easy deformation, and inconsistent pitch and concentricity, which ultimately affect cable performance.
[0003] To address the issue of unstable tension in the cable wrapping process in existing technologies, it is necessary to improve the structure of the cable wrapping and unwrapping device to solve the current technical problem. Utility Model Content
[0004] The purpose of this invention is to provide a novel device for controlling the tension of cable wrapping tape. The tension control structure and the film-releasing structure are designed as a whole. By controlling the tension of the wrapping tape through the tension control module, the stability of the wrapping tape tension can be controlled more accurately.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a novel device for controlling the tension of cable wrapping tape, comprising a wire core, wrapping tape, a hollow drive shaft, a tension control module, and a film-laying structure. The wire core is movably threaded along the central axis of the hollow drive shaft. The tension control module is fixedly sleeved on the hollow drive shaft. The film-laying structure is rotatably sleeved on the hollow drive shaft. The tension control module can adjustably apply braking force to the film-laying structure. The film-laying structure is wrapped with wrapping tape. After the cable is pulled out from the film-laying structure, it spirally wraps around the surface of the wire core.
[0006] To better realize this utility model, the tension control module is a hysteresis brake.
[0007] To better realize this utility model, the membrane dispensing structure is embedded with a magnetic suction element close to the tension control module.
[0008] To better realize this utility model, a bearing is sleeved on the outer wall of the hollow drive shaft, and the film-laying structure is rotatably sleeved on the hollow drive shaft through the bearing.
[0009] Beneficial effects: Compared with other existing tape wrapping devices, this utility model is a passive tape release device. It controls the tape release tension through a tension control module, which avoids the tension instability that occurs in active tape release structures. This can improve the stability of tape release tension during cable wrapping processing, improve product quality, and increase product yield. Attached Figure Description

[0012] 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.
[0013] Example like Figure 1 As shown, a novel device for controlling the tension of cable wrapping tape includes a wire core 5, wrapping tape 4, a hollow drive shaft 1, a tension control module 2, and a film-laying structure 3. The wire core 5 is movably threaded along the central axis of the hollow drive shaft 1. The movement of the wire core 5 is usually controlled by a cabling machine. The hollow drive shaft 1 is driven to rotate by conventional structures such as a drive motor and a drive pulley. These structures are all conventional designs in existing wrapping tape structures and will not be described in detail here. The tension control module 2 is fixedly sleeved on the hollow drive shaft 1. A bearing is sleeved on the outer wall of the hollow drive shaft 1. The film-laying structure 3 is rotatably sleeved on the hollow drive shaft 1 through the bearing. The tension control module 2 can adjustably apply braking force to the film-laying structure 3. The film-laying structure 3 is wrapped with wrapping tape 4. After the cable is pulled out from the film-laying structure 3, it is spirally wound around the surface of the wire core 5.
[0014] The working principle of this utility model can be summarized as follows: The tension control module 2 of the hysteresis brake structure operates synchronously with the hollow drive shaft 1. The film-laying structure 3 rotates freely around the hollow drive shaft 1. The hysteresis brake is activated, and it magnetically attracts the alloy magnetic attractor embedded in the film-laying structure 3, generating braking force. At this time, the film-laying structure 3 rotates synchronously with the tension control module 2. During the production process, the wrapping tape 4 is spirally wound around the core wire 5. The moving core wire 5 continuously pulls the wrapping tape 4 out of the carrier. The direction of the pull is opposite to the rotation direction of the film-laying structure 3. The wrapping tape 4 generates a pulling force, which is the same as the braking force applied to the film-laying structure 3 by the hysteresis brake. The film-laying structure 3 no longer rotates synchronously with the hollow drive shaft 1. The two opposing forces keep the wrapping tape 4 in a taut state.
[0015] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
