Description

Yarn breaking automatic stop device for warping machine

Technical Field

The utility model relates to the technical field of yarn breakage detection of a warping machine, in particular to a yarn breakage automatic stop device of the warping machine.

Background

Most of the yarn breakage automatic stop devices of the existing warping machine are photoelectric sensors of lead terminals, and the working principle is that when yarns pass through the sensors at a warping set speed, the sensors look at the yarns to work normally. When the yarn is disconnected, the yarn breakage sensor sends out a stop signal, so that the warping machine stops running; however, when the yarn is knotted after being disconnected and wound on the yarn guide roller, the yarn still normally passes through the sensor, the warping machine still normally works, no stop signal is sent, a large number of warp yarns are wound on the yarn guide roller, and therefore the broken yarn cannot be detected, the warp beam yarn is collapsed, and then broken ends and defects appear in warp knitting.
