Description

Technical Field

[0001] The utility model relates to the technical field of drag chains, in particular to a harness protection drag chain for a textile machine arm. Background Art

[0002] A robot is a machine device that automatically performs work. It can accept human commands, run pre-programmed programs, or act according to principles formulated with artificial intelligence technology. Robots are becoming more and more common in the textile industry. They can replace humans in high-intensity work and can work 24 hours a day, greatly improving textile efficiency. At the same time, they reduce the number of people in the factory and can reduce textile costs. When the textile robot arm is working, the wiring harness on the robot arm will be rubbed, so a drag chain is needed to protect the wiring harness of the textile robot arm. At present, the existing wiring harness protection drag chain of the textile robot arm can only move in one direction. When the textile robot arm moves in multiple directions, in order to ensure the operation of the textile robot arm, there will be multiple sections of the wiring harness exposed outside. If it is not protected for a long time, the wiring harness is easily damaged. Utility Model Content
