Improved flexible fireproof cable and wrapping device for production thereof

Abstract

The invention discloses an improved flexible fireproof cable and a wrapping device for production thereof, the cable comprises an inner rod, a plurality of unit wire bodies arranged on the periphery of the inner rod and a protection assembly wrapping the unit wire bodies, and the unit wire bodies are distributed on the peripheral side wall of the inner rod; the wrapping device comprises a base, a vertical mounting plate arranged on the base, a through hole formed in the center of the vertical mounting plate and used for allowing a conductor to penetrate through, and a wrapping assembly arranged on the vertical mounting plate and used for wrapping the conductor. A mica tape layer is additionally arranged on a conductor, a foaming ceramic silicon fire-resistant mica layer is arranged in a protection assembly, and the wrapping assembly composed of an installation circular ring, an installation column, driving teeth and a driving motor set is combined to achieve intelligent wrapping of a mica tape. The purposes of optimizing the overall structure of the cable, improving the performance of the cable, improving the wrapping quality and ensuring the production quality of the cable are achieved.

Description

technical field [0001] The invention relates to the field of cable production and manufacturing, in particular to an improved flexible fireproof cable and a wrapping device for production thereof. Background technique [0002] The cable is a kind of electric energy or signal transmission device, which is usually composed of several wires or groups of wires. During the preparation of the cable, it is necessary to wrap the surface of the cable with mica to better protect the cable. It is often necessary to use a wrapping machine, which is One of the special equipment for producing fireproof cables, control cables, communication cables, etc. However, the structure of the wrapping machine in the traditional process is complex, and at the same time, the cable is rotated during the production process, which is easy to cause damage to the cable, and the wrapping quality is not good. [0003] The information disclosed in this Background section is only intended to enhance the under...
