Description

TECHNICAL FIELD

[0001] The utility model relates to a textile machine technical field, specifically, a warp yarn breakage detection device for textile machine. BACKGROUND

[0002] At present, when weaving, the radial yarn breakage detection usually adopts the cooperation of the warp stop motion and the warp stopper, specifically, the warp yarn passes through the warp stopper and lifts up the warp stopper, when the warp yarn breaks, the warp stopper naturally falls down and contacts the warp stop motion to form a power loop, and the electric control system receives the signal and automatically stops in time.

[0003] When weaving filament fabrics, the filament fabrics cannot rub against the warp stopper (rubbing can damage the fibers and the yarn can be raised), so when weaving filament fabrics, the automatic radial yarn breakage detection mechanism is usually not set, but the manual method is adopted, that is, when the warp yarn breaks, the stopper is manually stopped and handled by the naked eye when the stopper patrols each machine, which often causes large-area fabric defects due to long-time failure to find the broken warp, and the fabric is downgraded or even scrapped.
