Description

Technical Field

[0002] In the textile industry, roving spinning is a crucial production link. Its quality and efficiency are directly related to the quality and production cost of textiles. As the core equipment for realizing this link, the design and performance of roving spinning device play a decisive role in improving spinning efficiency, reducing energy consumption and improving yarn quality. However, the roller shafts used in existing spinning equipment will have fibers and other impurities attached to their surfaces after long-term use. These attachments will not only reduce the operating efficiency of the roller shafts and increase energy consumption, but will also accelerate the wear of the roller shafts. When cleaning the roller shafts, they are mostly cleaned manually or cleaned by ultrasonic waves after being disassembled, but the efficiency is slow, which affects production efficiency. In addition, traditional spinning equipment is often unable to flexibly adjust the spacing between its roller shaft and the rubber roller shaft according to the different characteristics of the coarse yarn fibers and the requirements of spinning, resulting in the inability to fully control and stretch the fibers during the drafting process, and prone to problems such as fiber slippage or over-stretching.

[0003] In view of the above problems, the inventors propose a roving controllable feeding spinning device and a spinning method for solving the above problems. Summary of the invention
