Description

Low-pressure alarm device of air jet loom Technical Field The utility model relates to the technical field of air jet looms, in particular to a low-pressure alarm device of an air jet loom. Background The air jet loom requires stable air pressure during operation to ensure that the weft yarn can be accurately and timely drawn to the fell. When the air pressure is too low, it may cause a weft yarn to be drawn out of position or a time lag for the weft yarn to reach a prescribed position, thereby causing weft insertion failure. This not only affects the normal operation of the loom but also reduces the production efficiency. The low-pressure alarm can give an alarm in time when the air pressure is lower than a set value, and remind operators to take measures to adjust, so that weft insertion faults are avoided, and production efficiency is improved. The current chinese patent with bulletin number CN218711232U discloses a low-voltage alarm device for air-jet loom, which comprises an air pipeline, the periphery of the air pipeline is fixedly provided with a support ring, the middle of the support ring is rotatably provided with a rotating ring, the light is refracted towards a plurality of directions by mounting the light on the rotating ring, the light irradiation range is wider, people at different positions can find the light more easily, thus the machine can be stopped for the first time, accidents are avoided, and the safety is improved.
