Automatic drafting machine and drafting method thereof

Abstract

The invention discloses an automatic drafting machine and a drafting method thereof. The machine comprises a heddle, a rail, a crochet hook and a wallboard. The rail is half-enclosed, is composed of an upper concave block and a lower concave block which are oppositely arranged, and one side of the rail is fixed to the wallboard. The heddle is arranged on one side of the rail. A heddle eye is arranged at the position, corresponding to the position of the rail, of the heddle. After the crochet hook hooks a warp yarn, the crochet hook passes through the heddle eye and the rail, and then the drafting is completed. Nozzles are uniformly distributed in the length direction of the rail. The beneficial effects of the machine are that the nozzles are uniformly mounted in the rail through which the crochet hook passes; the nozzles are connected to an external air compression device, and the nozzles inject air in the rail; and when the crochet hook normally hooks the yarn and passes through the rail, the yarn which is attached on the surface of the rail as static electricity is generated due to friction can be blown out of the rail, so that mistakes can be reduced.

Description

technical field [0001] The invention relates to the field of textiles, in particular to an automatic drawing-in machine and a drawing-in method thereof. Background technique [0002] At present, people pay more attention to the weaving, breaking strength, pilling and other conditions of chemical fiber products, but they do not pay enough attention to the condition of the chemical fiber products. Internationally, the automatic stitching machine produced by STAUBLI (Stäubli) can greatly improve production efficiency, change the original manual stitching method, and combine the stitching and reed stages into one process. The existing equipment production method is The upper end of the yarn is cut and clamped, and the lower end runs a crochet needle in the track. Through the reciprocating motion, the crochet needle hooks the yarn and passes through the heald and the reed to complete the reed threading project. However, at present, due to the market demand for chemical fibers Di...

Problems solved by technology

[0007] In order to overcome the problems of high threading error rate and difficult monitoring of fine denier yarns in the prior art, the present invention provides an automatic threading machine, which includes heddles, rails, crochet hooks and wall panels. The rails are half Closed type, the upper concave block and the lower concave block are set up and down opposite each other, and one side is fixed on the wallboard. The heddle is set on one side of the track, and a heald eye is provided at the position corresponding to the track. , the crochet hooks the warp thread and passes through the heald eye and the track to complete the heald threading. The track is provided with an air jet device near the side of the wallboard, and the air jet device is provided with an air jet hole. The air jet hole faces the gap between the upper concave block and the lower concave block on the side away from the wallboard
