Description

Technical Field

[0001] The utility model belongs to the technical field of optical cable processing, and in particular relates to a bundled optical cable twisting device. Background Art

[0002] Optical fiber cable is manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical cables placed in a sheath as the transmission medium and can be used individually or in groups. Optical cable is mainly composed of optical fibers (glass fibers as thin as hair) and plastic protective casing and plastic outer skin. There is no gold, silver, copper, aluminum or other metals in the optical cable, and it generally has no recycling value. Optical cable is a communication line in which a certain number of optical cables are arranged in a certain way to form a cable core, which is covered with a sheath and some are also covered with an outer sheath to realize the transmission of optical signals. That is: a cable formed by an optical cable (optical transmission carrier) through a certain process. The basic structure of the optical cable is generally composed of several parts such as the cable core, reinforcing steel wire, filler and sheath. In addition, there are components such as waterproof layer, buffer layer, insulated metal wire, etc. according to needs.

[0003] A document with a publication number of (CN213240608U) was retrieved and disclosed a bundle optical cable twisting tooling, which specifically relates to the field of optical cable production; the bundle optical cable twisting tooling includes a threading plate, a threading seat, a centering die and a connecting rod, the threading seat and the centering die are respectively fixed on the main body of the production line, and the threading plate is fixed on the threading seat, and the purpose of adjusting the twisting pitch is achieved by adjusting the distance between the threading seat and the centering die; the tight-buffered optical cable passes through the threading holes distributed in an array on the threading plate, thereby realizing orderly twisting of the tight-buffered optical cable and avoiding tangled wires; by adding a connecting rod structure, the relative position of the threading plate and the connecting rod is made more accurate, thereby avoiding scratches on the surface of the tight-buffered optical cable.

[0004] The above-mentioned device passes several tight-buffered optical cables through the threading plate respectively to avoid tangled wires, and then passes them through the centering die and controls the diameter and roundness of the outer circle of the several tight-buffered optical cables after twisting through the core inside the centering die, which is convenient for the subsequent extrusion process. The twisting pitch of the several tight-buffered optical cables can be adjusted by adjusting the distance between the threading plate and the centering die. At the same time, the core and the threading sleeve are made of flexible material and have chamfered corners, which can reduce scratches on the tooling sleeve optical cable and aramid.

[0005] The above device passes the optical cable through the threading plate and then through the centering mold and through the core inside the centering mold. However, due to the size mismatch between the optical cable and the threading plate, the optical cable shakes left and right during the twisting process, which affects the stress of the optical cable after twisting, and there is a problem of wire explosion after twisting.

[0006] In view of this, the present utility model is proposed. Utility Model Content
