Description
Technical Field
The utility model belongs to the technical field of steel production, and particularly relates to an opening and closing control device of a drum-collecting flag switch.
Background
In the high-speed wire production, after the coil is connected in the upper coil collecting area, the descending speed of the core rod tray is quickly reduced after the flag switch signal is received, the tray is lowered in place, and after the coil rod is completely separated from the nose cone, the separating claw can be closed for next coil connection. However, because the rolling interval is influenced by non-human control factors, the distance between two rolls is possibly too short, so that an operator at the upper roll collecting station cannot successfully close the separating claw by means of the automatically-adjusted tray descending speed of the encoder, and the production accident of continuous rolls is caused. So that an operator lifts the flag switch by using a hook in the hand after the falling of the coil is about to be finished, ensures that the lowering speed of the core rod tray is regulated after the coil is collected in the collecting drum, and closes the separating claw. However, after the operator lifts the flag switch, the remaining time is short, and the hook in the hand can not be used for unhooking the coil tail ring, so that the coil blocking accident is caused, and the production yield is seriously affected.
