Plate feeding limiting structure

The utility model relates to the technical field of limiting structures, in particular to a plate feeding limiting structure which comprises a bottom plate, two supporting plates are fixedly connected to the top of the bottom plate, a limiting mechanism is arranged at the top of the bottom plate, and a limiting assembly is arranged at the top of the bottom plate. The limiting mechanism comprises a motor fixedly installed on the right side of the right supporting plate, an output shaft of the motor is fixedly connected with a first threaded rod, and the outer side of the first threaded rod is in threaded connection with two first threaded blocks. According to the plate feeding limiting structure, the limiting mechanism and the limiting assembly are arranged, so that the plate feeding limiting structure has a limiting function, the effect of limiting PS plates is achieved, the PS plates with different widths and different thicknesses are conveniently limited, the situation that follow-up procedures are affected
