Limiting plates 32 are fixed on both sides of the bottom of the storage box 31. The bottoms of the two limiting plates 32 are fixed to the top of the fixed seat 2. The height of the limiting plate 32 from the fixed seat 2 is the thickness of a steel plate. The reason for this design is that only one steel plate will fall down at a time, so that the stacked steel plates can be processed in sequence. A motor 33 is fixed at the bottom of the fixed seat 2, and the motor 33 is controlled by an external The output end of the motor 33 passes through the fixed seat 2 and extends to the top of the fixed seat 2.
