Description

Technical Field

[0001] This utility model relates to the field of textile automation equipment technology, and in particular to a high-efficiency doffing device for a twisting machine. Background Technology

[0002] A doubling twister is a twisting device, also known as a yarn-combining device (combining multiple strands into one), which can achieve two twists in one turn, increasing the twisting efficiency several times over compared to traditional twisting devices. The doubling twister consists of two layers. The bottom layer contains the raw yarn bobbin. The doubling twister uses a yarn-drawing device to draw the raw yarn, and then uses a twisting device to twist the drawn yarn into a single strand, which is then wound onto the twisting bobbin to complete the twisting process.

[0003] In textile enterprises, manual doffing is still the method used, which involves removing the full yarn bobbins from the bobbin frame of the twisting machine. The labor intensity of doffing workers is high, the efficiency is low, and too much manpower is wasted. Doffing workers need to work in high-intensity labor all year round, which can easily cause damage to their health.

[0004] Therefore, the development of a high-efficiency doffing device is of great significance for textile factories to improve production efficiency, reduce the labor intensity of workers, and enhance the automation and continuity of production.

[0005] This application discloses a doffing device for a doubling machine that can efficiently deliver the doffing coil, reducing the labor intensity of workers and improving production efficiency. Utility Model Content
