Automatic iron box feeding mechanism

The utility model provides an automatic iron box feeding mechanism, and relates to the technical field of packaging stations. Comprising a guide rail and a sliding seat moving front and back along the guide rail, a first electric cylinder is fixedly mounted on the lower surface of the sliding seat, a mounting plate is fixedly mounted at the top end of a piston rod of the first electric cylinder, an adjusting rail is fixedly mounted on the lower surface of the mounting plate and movably connected with two sliding blocks moving relatively, and a plurality of second electric cylinders are fixedly mounted on the lower surfaces of the sliding blocks; a piston rod jacking pipe of the second electric cylinder is fixedly provided with a magnetic attraction structure, the center of the adjusting rail is provided with a separation structure, and the two sliding blocks are symmetrically arranged relative to the separation structure. When the device is used for adsorbing and grabbing, the distance between the magnetic at
