Threading mechanism for warping machine

Abstract

The invention relates to the field of warping operation assisting equipment and discloses a lease thread threading mechanism for a warping machine. The threading mechanism is fixedly arranged on a warping machine frame and positioned between a yarn guide roller and an adjustable reed structure of the warping machine and comprises supporting seats on left and right ends of the frame, pulleys identical in height are horizontally and rotationally arranged on the supporting seats, a closed pull thread loop sleeves the pulleys at the left and right ends, two ends of the closed pull thread loop bypass outer end faces of the two pulleys respectively, and portions, between the two pulleys, of the pull thread loop are two linear sections in horizontal arrangement at the same height. When one of thepulley rotates, the linear sections of the pull thread loop are driven to move linearly while the other pulley is driven to rotate through the pull thread loop, the pull thread loop penetrates warpsof the warping machine, each warp bypasses the upper end or the lower end of the pull thread loop, and adjacent warps are positioned at different ends of the pull thread loop. The threading mechanismis structurally simple and practical and quick and convenient to thread, labor intensity is reduced, and operating efficiency is improved.

Description

technical field [0001] The invention relates to the field of warping operation auxiliary equipment, in particular to a threading, splitting and stranding mechanism used on a warping machine. Background technique [0002] The purpose of warping is to wind a certain number of cheeses in parallel on the warp beam with appropriate and uniform tension according to the length and width required by the process design, so as to prepare for warp yarn sizing and weaving beams; in order to facilitate It is easy to separate the beams and sizing on the sizing machine to avoid yarn twisting when the yarn is sizing. It is necessary to add a split line to each warp beam during warping so that the warp yarns on the warp beam are divided into upper and lower parts. The sub-strands are axial lines. At present, there is no convenient device for the warping machine to thread the sub-strands. When threading the sub-strands, manual threading operation is required. Generally, there are many warp ya...

[0002] The purpose of warping is to wind a certain number of cheeses in parallel on the warp beam with appropriate and uniform tension according to the length and width required by the process design, so as to prepare for warp yarn sizing and weaving beams; in order to facilitate It is easy to separate the beams and sizing on the sizing machine to avoid yarn twisting when the yarn is sizing. It is necessary to add a split line to each warp beam during warping so that the warp yarns on the warp beam are divided into upper and lower parts. The sub-strands are axial lines. At present, there is no convenient device for the warping machine to thread the sub-strands. When threading the sub-strands, manual threading operation is required. Generally, there are many warp yarns in each warp beam. The yarns are separated one by one, which means that the sub-skeins have to pass through a large number of yarns one by one, and the action is repeated many times, so that wearing a sub-skein requires the workers to concentrate very much, causing workers to be very nervous. Fatigue, quite time consuming, inefficient threading, and at the same time, one warp beam often involves the need to thread multiple sub-strands, so that repeated inefficient operations are required
