Stacking device for corrugated board processing

The utility model relates to the technical field of paperboard processing, in particular to a stacking device for corrugated paperboard processing, which comprises a door-shaped frame, square openings are symmetrically arranged on two side plates of the door-shaped frame, a fixing rod is fixedly connected between the top and the bottom of an inner cavity of each square opening, a spring is sleeved on the outer wall of each fixing rod, and a support plate is slidably connected to the outer wall of each fixing rod. Two groups of supporting plates are arranged in the door-shaped frame, a pallet is placed between the two groups of supporting plates, the pallet is used for stacking paperboards, and an openable hinge door is hinged to one side between the two side plates of the door-shaped frame. And the pallets and the supporting plates can slowly descend along with the number of the paperboards during stacking, the stacking orderliness is guaranteed, meanwhile, after stacking is completed, the stacked paperboards
