Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textile machinery, in particular to a yarn tension mechanism of a warp knitting machine. Background Art
[0002] A warp knitting machine is a machine used to produce knitted fabrics. It uses one or several groups of parallel arranged yarns to form loops on all the working needles of the warp feeding machine at the same time to form knitted fabrics. The warp knitting machine is mainly composed of a weaving mechanism, a comb slidable mechanism, a warp feeding mechanism, a pulling and winding mechanism and a transmission mechanism.
[0003] The warp knitting machine needs to adjust the tension during the weaving process to maintain the stability and consistency of the yarn. This is because the yarn is prone to stretching and deformation when subjected to warp tension, weft tension and the piercing force of the knitting needle. When the tension is too large, the yarn may even break. At the same time, in order to prevent problems such as uneven tightness and uneven fabric, the tension needs to be adjusted to keep it constant. In addition, different fabric specifications and production processes have different requirements for tension. Therefore, the warp knitting machine needs to have a flexible tension adjustment function to adapt to different production processes and fabric requirements. In order to solve the above problems, the yarn tension can be adjusted accordingly according to demand during the manufacturing process of the warp knitting machine, so as to avoid problems such as yarn breakage, uneven tightness and uneven fabric. For this reason, we propose a yarn tension mechanism for a warp knitting machine. Utility Model Content
