[0031] The overall action mode of the jaw automatic transmission equipment of the present invention is: the vibration plate is started, and the jaws in the hopper enter the spiral conveying track from the track feeding port; when passing through the first screening mechanism, the first screening baffle bar screens the jaws in the lying state and the upright state, and only the jaws in the lying state can pass through the first screening port, and the jaws in the upright state are blocked by the first screening baffle bar and fall back into the hopper; when passing through the second screening mechanism, the jaws with the jaw ends facing inwards will fall back into the hopper under the action of the second screening baffle bar, and the jaws with the cylindrical ends facing inwards will continue to move forward along the spiral conveying track, and under the movement limiting action of the guide rod, the gap between the jaws forms a matching press with the guide rod.

When each positioning sensing sensor detects that the jaws are in place, the feeding vibration plate stops vibrating, and the transverse cylinder drives the push guide tube to move horizontally, so that the push guide tube and the push rod are on the same axis. At the same time, the travel switch on the transverse cylinder triggers a signal, and the push cylinder drives the push rod to push vertically. The push rod passes through the push channel and pushes the jaws in the push channel to the next processing station. The push cylinder drives the push rod to reset to the initial position.
