A kind of flexible cable for drag chain

Abstract

The invention provides a flexible cable for a tow chain. The flexible cable is characterized by comprising conductors, insulation layers, polypropylene fillers, a non-woven fabric band, an inner covering, a metal braided shielding layer and an oversheath, wherein the conductors are extruded by the insulation layers to form insulation cores, a cabling core is formed by twisting the multiple insulation cores around the multiple polypropylene fillers, the non-woven fabric band wraps the cabling core, and the non-woven fabric band is successively externally provided with the inner covering, the metal braided shielding layer and the oversheath. The flexible cable for the tow chain has the advantages of quite high mechanical tensile strength, wear resistance, corrosion resistance, interference immunity, reciprocating high-speed bending resistance, safety, environmental protection, improved processing performance and the like.

Description

[0001] 【Technical field】 [0002] The invention relates to a flexible cable for drag chains. [0003] 【Background technique】 [0004] With the continuous advancement of science and technology, mechanical automation technology has been widely used in my country's machinery manufacturing industry, realizing continuous, effective and automated production in the manufacturing process, and speeding up the process of production and processing. Mechanical automation has become an important part of contemporary advanced mechanical manufacturing technology. However, the cables used in machinery as signal control and power transmission cannot meet their special requirements, and the phenomenon of cable entanglement, wear, pull-off, and scatter occurs, resulting in frequent equipment failures. The advent of drag chains in 1953 played a role in traction and protection for cables used in machinery, reducing the frequency of equipment failures. The entire production line was shut down, cau...

AI Technical Summary

Problems solved by technology

However, most of the existing towline cables are ordinary cables or slightly modified ordinary cables. Most of the production uses nitrile polyvinyl chloride as the insulation and sheath material. Destruction affects the performance of the cable and has a shorter service life

It is easy to produce toxic halogen gas during production and disposal, causing harm to human body and environment

And most towline cables are not strong enough. In the occasion of reciprocating high-speed movement, the cables often "spin" and "break". A towline often needs to replace the cable several times.
