Background technique

Textile machine, also known as spinning machine, loom, cotton spinning machine, etc., the ancient textile machine is a loom driven by manpower. A textile machine is a device that processes raw materials such as thread, silk, and hemp into silk threads and then weaves them into fabrics. When weaving, we need to use a warp let-off device, which transports the warp yarns arranged on the weaving shaft into the machine, and mechanically synthesizes the warp yarns into cloth and winds them up. The traditional let-off device is inside the textile machine. Due to the limitation of space, less warp yarns are wound on the spool of the let-off device, so the spool is replaced more times, which affects the efficiency of production. Therefore, the existing In the technology, the let-off device is moved to the outside of the textile machine, which increases the length, width and height of the let-off device, so that more warp yarns can be stored on the spool of the let-off device, reducing the number of replacement spools and improving the production efficiency.

However, the structure of the existing warp let-off device is fixed and cannot be adjusted according to the length of the wire reel. The length of the wire reel is different. Therefore, different warp let-off devices need to be used when loading wire reels of different lengths. It is limited in use and has poor versatility.
