Hand-operated and easy-to-adjust warp yarn pulling device

Abstract

The invention provides a hand-operated and easy-to-adjust warp yarn pulling device, which comprises a lifting pull bar. The lifting pull bar is in the form of a horizontally arranged straight bar. The lifting pull bar is provided with more than two vertical hole ducts arranged side by side. Warp yarns are arranged to pass through the vertical hole ducts. The left side edge of each lifting pull bar is in hinged connection with a pressing key corresponding to one vertical hole duct. Each vertical hole duct, corresponding to the left part of the lifting pull bar, is machined with a horizontal tightening groove. The inner side of a lower pressing plate is provided with a horizontally extending tightening raised head. The vertical hole ducts vertically pass through the tightening groove. When the lower pressing plate of the pressing key is pressed down, the tightening raised head goes deep into the tightening groove. The warp yarns in corresponding vertical hole ducts are pressed tightly onto the lifting pull bar. By means of the device, the corresponding warp yarns can be pulled up easily only through pressing the key on the lifting pull bar. Therefore, by means of the device, the pulling operation of the warp yarns is faster in speed and more efficient.

Description

technical field [0001] The invention relates to the technical field of fabric processing, in particular to a manually adjustable warp thread pulling device. Background technique [0002] Fabric is woven from yarn through warp and weft structure, and fabric is an important material for people's production and life. Therefore, the processing of fabrics is an important production and management activity for people. Although most of the current fabrics are completed by electric and automated looms, many traditional craft textile processes can only be completed by hand weaving. For example, some weaving techniques used in traditional Song brocade, Yun brocade, and Shu brocade can only be done by traditional hand-weaving. In the traditional artificial loom, the weft thread passes back and forth between the open warp threads through the shuttle equipped with thread balls, so as to realize the weaving of the weft thread to the warp thread. In order to make the warp and weft struct...

AI Technical Summary

Problems solved by technology

The warp lifting process of hand looms is usually done manually by pulling with both hands, which is relatively laborious, and the process of selecting warp threads is relatively cumbersome and time-consuming, which greatly affects the efficiency of hand-looming. It is difficult to ensure the same tension force on the warp threads during the warp lifting process, and it is easy to cause warp leakage, which affects the quality of the weaving pattern
