Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of weaving machine accessories, in particular to a yarn tension equalizer for a weaving machine. Background Art
[0002] When preparing stretch clothing fabrics, yarn is often used as the main raw material for processing. When using a weaving machine to prepare stretch clothing fabrics, yarn tension is one of the key factors affecting weaving quality and production efficiency. Traditional weaving machines have some shortcomings in yarn tension control, which leads to unbalanced yarn tension during the weaving process. This unbalanced tension not only affects the quality of the fabric, such as wrinkling of the base fabric, yarn breakage, and seersucker, but also reduces the production efficiency of the weaving machine.
[0003] Specifically, existing weaving machines rely primarily on mechanisms such as yarn guides and yarn pressure plates to control yarn tension. However, these mechanisms often present several challenges in practical applications. For example, improperly designed yarn guides can lead to uneven yarn tension distribution during the yarn guidance process. Furthermore, as the yarn diameter decreases, the pressure exerted by the yarn pressure plate decreases, reducing the friction between the yarn and the yarn pressure plate. This ultimately leads to greater variations in yarn tension, making it impossible to adjust the pressure according to actual needs and maintain appropriate tension. In light of this, we propose a yarn tension equalizer for weaving machines. Utility Model Content
