Yarn tensioning mechanism of water-jet loom

Abstract

The invention discloses a yarn tensioning mechanism of a water-jet loom. The mechanism comprises a rack which is U-shaped, wherein a first rotating shaft, a second rotating shaft and a third rotatingshaft are rotationally connected to the inner wall of the rack from left to right in sequence; the second rotating shaft and the third rotating shaft are both higher than the first rotating shaft, andthe second rotating shaft and the third rotating shaft are the same in height; a first transmission roller is fixedly connected to the outer side of the first rotating shaft in a sleeving manner, a second transmission roller is fixedly connected to the outer side of each of the second rotating shaft and the third rotating shaft in a sleeving manner; a gantry support corresponding to the second rotating shaft and the third rotating shaft is fixedly connected to the outer side wall of the rack; a driving motor is fixedly connected to the side wall of the gantry support; and the driving motor isconnected to the second rotating shaft and the third rotating shaft via transmission mechanisms. The yarn tensioning mechanism of the water-jet loom is suitable for adjusting yarn tension of a water-jet loom, and is simple in structure; and the transmission mechanisms can achieve the auxiliary conveying effect, which is beneficial to yarn transportation.

Description

technical field [0001] The invention relates to the technical field of water jet looms, in particular to a yarn tensioning mechanism of a water jet loom. Background technique [0002] When the loom is weaving, it generally uses many kinds of warp yarns to weave some desired cloth. In traditional crafts, especially for yarn-dyed, silk, and woolen weaving, due to the complex fabric structure, large warp density, and many varieties, the threading process is complicated, with hundreds of threads per cycle. [0003] The water-jet loom is a shuttleless loom that uses a jet of water to pull the weft through the shed. Water-jet weft insertion has greater friction and traction on weft yarn than air-jet weft insertion, and has less diffusivity, which is suitable for weft insertion of filaments such as synthetic fibers and glass fibers with smooth surfaces. When the loom is working, because the warp yarn is small, it is easy to break during the weaving process of the loom. After the ...

AI Technical Summary

Problems solved by technology

When the loom is working, because the warp yarn is small, it is easy to break during the weaving process of the loom. After the warp yarn is broken, the yarn needs to be loosened, and then the disconnected yarn should be connected, and then the yarn needs to be loosened during the weaving process. The tension of the yarn is adjusted, but the existing tension mechanism is more complicated and inconvenient to adjust. Therefore, we propose a yarn tension mechanism of a water jet loom to solve the above-mentioned problems
