Description

Technical Field

[0001] This utility model relates to the field of wire and cable technology, and in particular to a device for stabilizing the core of a wrapped cable in cable production. Background Technology

[0002] Cable wrapping machines are widely used in the wire and cable industry, primarily to wrap one or more layers of dielectric material around cables to improve their performance. The quality of the wrapping significantly impacts cable performance and production costs. Concentric wrapping machines ensure complete alignment of the cable's central axis and the wrapping tape axis, resulting in a compact wrapping head structure, low rotational inertia, and high wrapping efficiency. To ensure tight wrapping of the conductor, the wrapping tape is tensioned. Therefore, during the wrapping process, the conductor experiences a radial force, causing radial displacement and unstable wrapping angles. This results in an uneven surface on the conductor after wrapping, ultimately affecting the quality of the finished wire and cable. Summary of the Invention

[0003] The purpose of this invention is to provide a device for stabilizing the core of a wrapped cable in the production of cables, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The bottom of the jacket is provided with an opening, and a countersunk hole is provided on the side wall of the jacket corresponding to the opening. The countersunk hole is provided with internal threads, and a screw is installed on the countersunk hole through the internal threads.

[0007] The guide rod is parallel to the wire core.

[0008] The sleeve and screw are both perpendicular to the guide rod and the wire core.
