Stacking machine for automatically stacking packing box bodies

The utility model discloses a stacking machine for automatically stacking packing box bodies. The machine is that two vertical supporting columns and a cross beam form a door shaped structure; a clamping driving device correspondingly controls a front clamping claw and a rear clamping claw in order to clamp and hold a box body on a conveying line or release the box body on a pallet, so that a forklift can conveniently carry the box bodies from the pallet to a warehouse or other specified position together; a transverse driving device controls a transverse moving seat to move leftwards and rightwards along the cross beam; a vertical moving seat, the front clamping claw and the rear clamping claw can move leftwards and rightwards together to be above the conveying line end or the pallet; a vertical driving device can control the vertical moving seat to move up and down along the transverse moving seat, the front clamping claw and the rear clamping claw so as to clamp or release the box bodies, so that the box bodies can be automatically carried and stacked; in addition, the machine is simple in structure, small in space used, and large in travel while moving leftwards and rightwards or moving up and down, and can be applied to automatic carrying of various box bodies with different specifications; therefore, the labor cost can be reduced, and the production efficiency can be increased.
