Spun yarn broken end automatic stop device suitable for spinning flax siro yarn

Abstract

The invention discloses a spun yarn broken end automatic stop device suitable for spinning flax siro yarns, a front mounting plate is arranged at one end of a middle mounting plate, a rear mounting plate is arranged at the other end of the middle mounting plate, and a laser detection head is fixedly mounted at the top end of the middle of the front side of the middle mounting plate; tension is actively applied to the yarn through continuous airflow, so that yarn breaking points are concentrated, when structural defects or weak strength points exist on a single yarn, the yarn will be broken preferentially when moving to the top of the extrusion sliding block, and the yarn breakage rate is increased. According to the yarn breakage automatic stop device, the detection process of the yarn breakage automatic stop device is optimized, original passive detection is changed into induced active detection, the randomness of the yarn breakage point is effectively reduced, a worker can rapidly determine the breakage point after the yarn is broken, and then the yarn connection repair efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a spun yarn breakage automatic stop device suitable for spinning flax siro yarn. Background technique [0002] Siro spinning, also known as parallel spinning, domestically known as A and B yarns, was officially named Siro spinning recently. Siro spinning is to feed two rovings with a certain distance on the spinning frame. The two single-yarn whiskers are output, and the single-yarn whiskers have a small amount of twist due to the transfer of twist. During the progress of the project, the yarn will break due to the influence of the tension change on the yarn and the strength of the yarn itself. In order to ensure the continuous operation of the yarn, it is necessary to use the yarn breakage detection device to detect the yarn breakage. And shut down the spinning equipment in time after the detected end breakage; [0003] However, at present, the end-break auto-stop device can ...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a spun yarn breakage automatic stop device suitable for spinning flax twin yarn, which can effectively solve the problem that the end breakage stop device proposed in the background technology can only passively detect broken ends during use, and the yarn breakage The position of the broken end appears randomly on the spinning equipment, so that after the detection of the broken end, the two broken ends are too far apart and cannot be connected quickly, which reduces the timeliness of the broken end detection device and also causes yarn reconnection. The problem of hindering and reducing the efficiency of yarn breakage wiring
