AI Technical Summary
In single-filament and multi-filament looms, excessive tension during warp feeding causes warp yarns to break, and existing technologies cannot effectively adjust the tension.
A tension adjustment mechanism including a winding motor, a cycloidal support, and a winding drum is designed. The number of yarn winding turns and the height are controlled by the forward and reverse rotation of the winding motor. The tension of the warp yarn is adjusted by friction. The translation of the winding slider is achieved by the meshing of the circumferential gear and the winding toothed disc, thus avoiding cross-winding.
It effectively regulates the tension of the warp yarns, prevents warp yarn breakage, ensures stable conveying, reduces yarn wear, and improves the working reliability of the loom.
