Abstract

The invention discloses a cord thread detection device, which comprises a diameter detection sheet. A circular detection hole for a cord thread to pass through is disposed in the diameter detection sheet. The circular detection hole comprises a first circular truncated cone hole, a first cylindrical hole and a second circular truncated cone hole. The first truncated cone hole, the first cylindrical hole and the second circular truncated cone hole are arranged coaxially in sequence according to the passing direction of the cord thread. The first truncated cone hole, the first cylindrical hole and the second circular truncated cone hole are of an integrated structure. The diameter of the first cylindrical hole is equal to the diameter of the smaller surfaces of the first and second truncated cone holes. The diameter of the first cylindrical hole is D1mm larger than that of the cord thread, and the D1 is 0.015-0.025. According to the invention, the cord thread detection device can detect defects of tiny broken wires, twisted defects and the like in the making process of the cord thread.

Description

technical field [0001] The invention relates to a device for cord generation, in particular to a cord detection device. Background technique [0002] Cords are also called cords, which can be used as reinforcing materials for rubber products such as tires, conveyor belts, and transmission belts, that is, skeleton materials, mainly for tires. Cord materials include cotton yarn, viscose fiber, polyamide fiber, polyvinyl alcohol fiber, glass fiber, aramid fiber and steel wire, etc., and their properties are different. It is often selected according to the performance requirements and cost of rubber products. Steel cords are mainly used in tires. [0003] The cord is made of multiple silk threads through drawing, twisting and other processes. In the production process, phenomena such as broken wires, bulging wires, bent wires, twisting defects, etc. occur from time to time, especially in the process of producing steel cords, the above phenomena are more prominent. This not on...
