Abstract

The utility model relates to an automatic stopping device of a steel wire bunching machine when wire breakage occurs. The utility model is characterized in that a powerdown detecting wire TCS of the device is positioned at the outer side of a stranded steel wire, when wire breakage phenomenon of one of the steel wires occurs, the broken steel wire contacts the powerdown detecting wire TCS, a triode BG1 switches into conduction when being power on, while a triode BG2 quits the state of saturation and enters a cut-off state, and then, an electric relay J1 releases when losing electricity, so that connection points 5 and 6 of the electric relay J1 return to original positions, and as a result, a circuit turns into a self-holding state. Furthermore, connection points 3 and 4 of the electric relay J1 also return to original positions, an electric relay J2 is attracted to start when getting electricity, the connection points 3 and 4 of the electric relay J2 are switched off, and then an electric machine controller loses electricity, and stops the output of exciting voltage, and as a result, a slip motor stops running as well as the bunching machine is out of action. Meanwhile, connection points 6 and 8 of the electric relay J2 are closed, so that a buzzer FM is power on and sounds to remind operating staffs to deal with the matter in time, so that the bunching quality of the product is ensured and rejected products which are processed with less strands can be avoided.
