Weft insertion mechanism of jet loom
technical field
[001] the utility model belongs to the field of textile machinery, in particular to a weft insertion mechanism of a jet loom.
Background technology
[002] weft insertion of jet loom is mainly completed by the pressure medium ejected from the main nozzle and several auxiliary nozzles. The solenoid valve controls the on and off of the pressure medium source on the main and auxiliary nozzles to ensure the smooth weft insertion of the jet loom.

The existing weft insertion mechanism of jet looms usually uses one solenoid valve to control multiple auxiliary nozzles. The working principle of the solenoid valve is to control the opening of the valve core by the coil.

The electromagnetic force generated by the electrified coil is used to push the valve core to move away from the valve port. The solenoid valve is in the open state. When the coil is powered off, the spool is reset and compressed by the spring elasticity, The solenoid valve is closed. When the solenoid valve is opened, it needs to overcome the spring force by the electromagnetic force to push the valve core to move, so the spring force is generally not too large, then the valve core moves slowly when the solenoid valve is closed, resulting in the waste of pressure medium.

However, the energy consumption of jet loom pressure medium preparation is relatively large, so the waste of pressure medium also causes large energy consumption.

[003] the purpose of the utility model is to overcome the defects of slow closing of the electromagnetic valve of the existing weft insertion mechanism of the jet loom, resulting in waste of pressure medium and large energy consumption, and to provide a weft insertion mechanism of the jet loom which can reduce energy consumption.
