Description

Technical Field

[0001] The utility model relates to the technical field of wire rope manufacturing, in particular to a polyester wire rope twisting mechanism. Background Technique

[0002] In the textile industry, polyester wire ropes are widely used due to their excellent physical and chemical properties. However, traditional polyester wire rope twisting methods are difficult to process multiple strands of wire ropes simultaneously. To solve this problem, a new type of polyester wire rope twisting mechanism needs to be developed. By optimizing the structural design and working principle, efficient twisting of multiple strands of polyester wire ropes can be achieved.

[0003] A polyester wire rope twisting mechanism with the reference publication number CN217896050U has a first motor fixedly arranged inside a protective shell on the upper end face of the machine body. A first rotating shaft is fixedly arranged at the output end of the first motor. A runner is fixedly arranged at one end of the first rotating shaft away from the first motor. A plurality of through holes are spaced apart near the edge of the runner. Shaft wheels are rotatably arranged in a plurality of through holes. In this twisting mechanism, the polyester wire rope passes through the runner through the shaft grooves on the shaft wheels in the plurality of through holes. The first motor drives the runner to rotate to twist and form the polyester wire rope. The third motor drives the wire collecting cylinder to rotate, and the air cylinder drives the wire collecting cylinder to reciprocate up and down to rotate and collect the twisted polyester wire rope. The runner is provided with a plurality of through holes, and multiple strands of polyester wire ropes can be placed according to needs to meet the twisting of multiple strands of wire ropes. The overall device has a simple structure and is easy to operate, and can realize the twisting and forming of multiple strands of polyester wire ropes. According to the above, although this twisting mechanism can be well applied, it usually twists multiple polyester wire ropes together by rotating the runner for winding and collecting, and the position of the wire shaft is in a fixed area, which makes the polyester wire ropes extremely prone to entanglement and knotting, often bothering users.
