Automatic lifting and material distributing device

The invention discloses an automatic lifting and material distributing device which comprises a top plate, a first middle plate, a second middle plate and a bottom plate which are sequentially arranged from top to bottom. A lifting air cylinder is arranged in the middle of the second middle plate in the vertical direction in a penetrating mode, the top end of the lifting air cylinder is sleeved with a first ejecting pin, the upper end of the first ejecting pin is rotationally connected with the top plate, and a material receiving groove is formed above the top plate. Four second ejecting pins are arranged on the periphery of the first middle plate and are connected with the first middle plate through bearings. A limiting frame is arranged between the first middle plate and the second middle plate, and a material distributing air cylinder is arranged on one side of the limiting frame. Check blocks are arranged at the positions, corresponding to the second ejecting pins, of the upper and lower portions of the l
