A loom broken yarn capture device

Abstract

The invention provides a weaving machine broken yarn catching device. The weaving machine broken yarn catching device comprises a catching platform which is arranged on one side of a warp yarn conveying plane in parallel, warp yarns are provided with presser sensors for monitoring whether the warp yarns are broken, each warp yarn is correspondingly provided with a catching groove in the catching platform, the two ends of each catching groove are provided with an air nozzle and an extraction opening, the spraying direction of each air nozzle is consistent with the conveying direction of the warp yarns, the spraying quantity of each air nozzle is equal to the extraction quantity of the corresponding extraction opening, and a presser controls each air nozzle. According to the weaving machine broken yarn catching device, pressure intensity on one side of each warp yarn is reduced by means of air flow sprayed through the corresponding air nozzle, the broken yarns enter the catching grooves by being sucked by the air flow, and meanwhile tension of the warp yarns is kept by means of friction between the air flow and the weft yarns and the warp yarns are prevented from flying.

Description

Technical field [0001] The invention relates to the field of textile machinery, in particular to a broken yarn capture device suitable for looms. Background technique [0002] The looms are all equipped with a warp break self-stop device, the purpose of which is to detect warp break and send a stop signal. Their types: photoelectric (far-infrared detection), stop-and-go rack, carding and rotating. At present, the stop frame type is mostly used, and its working principle: the stop frame is installed between the back beam and the heald frame, and there are several rows of stop bars on it. The warp stop strip is a combination of inner and outer conductors separated by a thick plastic film to form an open circuit. Many warp stop pieces are set on the warp stop strip, and each warp yarn passes through a warp stop piece alone. When the loom is running, the warp yarn tension will pull up the warp stop piece so that it does not contact with the inner conductor of the warp stop pie...

AI Technical Summary

Problems solved by technology

[0003] The warp breakage self-stop device detects warp yarn breakage only after the warp yarn breaks, so this device has a certain delay and cannot be stopped in time. However, modern high-speed looms have high requirements for speed, delayed shutdown, and random flying after breakage. The warp will affect the safety of loom operation
