Shuttle collision preventing device of netting machine

Abstract

The invention discloses a shuttle collision preventing device of a netting machine, which is used for changing the warp shading time of the netting machine and comprises a shuttle box (3). The shuttle collision preventing device is characterized in that a light receptor (2) is arranged at the upper part of the shuttle box (3), the position of the light receptor is higher than that of the shuttle tail of a copper shuttle (1), and a light projector is arranged at the other end of the shuttle box (3) and corresponds to the light receptor (2). The shuttle collision preventing device disclosed by the invention has simple structure, is used for advancing the warp shading time of the netting machine so as to be staggered with the abnormal shuttle jumping time of the copper shuttle, thereby ensuring that the netting machine stops operating when abnormal copper shuttles jump occurs to guarantee the normal operation of machine equipment.

Description

technical field [0001] The invention relates to a net weaving machine, in particular to an anti-collision shuttle device of the net weaving machine. Background technique [0002] At present, the anti-collision shuttle device of the weaving machine is controlled by a light emitter, a light receiver and a time-limited proximity switch. Since the light emitter and the light receiver are installed on the shuttle box, and their positions are in the middle of the holes of the shuttle discs at both ends, the time when the warp thread of the weaving machine is unhooked and the shading time is close to the time when the abnormal copper shuttle jumps, that is, when the warp thread of the weaving machine is unhooked normally. When the hook produces shading (the light receiver cannot receive the light source of the light emitter), the time-limited proximity switch is in working state, and the weaving machine does not stop running. And this moment, if encounter abnormal copper shuttle, ...

AI Technical Summary

Problems solved by technology

At this time, if there is an abnormal copper shuttle, it will cause the copper shuttle to jump out of its original position and need to be stopped. However, because the time-limited proximity switch is in working condition, the weaving machine cannot stop running.

Therefore, the lower hook plate of the weaving machine will damage the copper shuttle or even other parts of the weaving machine, which will affect the quality of the mesh and reduce the work efficiency.
