Wire and cable cotton thread automatic cutting device and method for cutting cotton thread

Abstract

The invention discloses an automatic cutting and removing device for cotton threads on electric wires and cables. The device comprises a positioning plate provided with a limiting hole, a thread pressing air cylinder connected with a thread pressing rod is arranged on the positioning plate, the output end of the thread pressing air cylinder is connected with the thread pressing rod, and a cotton thread cutting mechanism in rotatable connection with a support is arranged on one side of the positioning plate and provided with a gas-blowing port connected with high-pressure gas. When the automatic cutting and removing device works, the ends of the electric wires and cables are placed into the limiting hole, a control module controls the high-pressure gas blown out of the gas-blowing port to blow the cotton threads to the other ends of the electric wires and cables to be bent, then the thread pressing air cylinder clamps and fixes the electric wires and cables and the bent cotton threads through the thread pressing rod, the cotton thread cutting mechanism with a blade clamps the bent positions of the cotton threads on the electric wires and the cables, then a drive motor drives the cotton thread cutting mechanism through a transmission component to rotate, and therefore the cotton threads are cut and removed. Due to the fact that the automatic cutting and removing device can automatically cut and remove the cotton threads on the electric wires and cables, the cutting efficiency is improved, and meanwhile the problems that when cut manually, the reinforcing threads are not uniform in length, and follow-up welding is affected are solved.

Description

technical field [0001] The invention relates to the technical field of electric wire and cable cutting, in particular to a cotton thread cutting device and a cotton thread cutting method with enhanced tensile strength in electric wires and cables. Background technique [0002] Existing multi-core wires and cables are usually provided with reinforcing ribs, such as cotton threads outside the outer insulation of the multi-cores, to enhance the tensile performance of the wires and cables. However, when this kind of wire and cable is welded, such as when welding with a USB terminal, the reinforcing rib needs to be cut off, otherwise the welding will be affected. Existing wires and cables are manually cut off the reinforcing ribs before welding. On the one hand, the efficiency is low. On the other hand, the lengths of the removed reinforcing ribs are different, and even the reserved reinforcing ribs are too long, which affects the welding operation. Contents of the invention ...
