Abstract

[0002] Yarn tensioning is a very important link in the textile yarn manufacturing process. It is mainly used to provide the expected yarn tension and maintain the yarn surface tension. In the existing textile process, large-scale integrated equipment is generally used for assembly line production. Usually, a tensioning mechanism is set between each process to ensure the tension of various knitted products. For example, when the yarn is pulled off the warp beam and conveyed to the loop forming tool, a yarn tensioning mechanism is set between the warp beam and the loop forming tool to ensure the tension of the yarn during the conveying process and avoid the yarn from being too tight or too loose and slipping during the conveying process.

Moreover, the guiding method of the entire tensioning mechanism generally only uses an axis for guiding, which makes the stability of the yarn poor. Therefore, it is urgent to design a yarn guiding tensioning mechanism to solve the above problems. Utility Model Content
