[0015] The present invention provides a stacking device for corrugated paper packaging, which has the following beneficial effects:

[0016] (1) In this invention, when the lead screw drives the driving block and the placement plate to rise, the driving block squeezes the trapezoidal plate and the movable plate to move. When the movable plate moves, it drives the connecting plate and the push rod to move, so that the arc plate presses the hollow rod, the movable rod and the support rod to rotate downward. The support rod supports the base. When the connecting rod moves, it drives the piston plate to squeeze the liquid inside the hydraulic cylinder into the inside of the hollow rod. The liquid pushes the movable rod to move to the outside of the hollow rod, thereby increasing the support range of the support rod for the base and preventing the center of gravity of the support frame from rising and causing it to tip over after the placement plate drives the corrugated paper to rise.

[0017] (2) In the present invention, when corrugated paper is placed on a placement board, the guardrail will squeeze the corrugated paper so that the front and back of the corrugated paper are aligned, thereby preventing the front and back positions of the corrugated paper from being offset and prone to tipping over. After the height of the corrugated paper is increased, the guardrail will loosen its grip on the bottom of the corrugated paper to prevent the guardrail from affecting the bottom of the corrugated paper from detaching from the placement board when the pushing plate pushes the corrugated paper to detach from the placement board. At the same time, when the connecting block moves, the bending plate will hit the elastic sheet, thereby driving the guardrail to vibrate, thereby preventing the friction between the corrugated paper from being too large and making it difficult to align the front and back.

[0018] (3) In the invention, when the height of the placement plate is increased, the extrusion frame will drive the protrusion to squeeze the elastic plate, so that the height of the concave plate and the pulley is increased, and the pulley will contact the corrugated paper, thereby reducing the friction between the corrugated paper and the placement plate. At the same time, the L-shaped plate will push the rotating wheel and the friction plate to move, and the friction plate will push the pulley to rotate. The pulley will drive the corrugated paper to move toward the support frame to prevent the corrugated paper from moving to the left when the height of the placement plate and the corrugated paper is increased, affecting the stability of the corrugated paper. At the same time, when the pushing plate moves, it will intermittently contact the pulley, so that the pulley will move up and down and hit the corrugated paper, and when the pushing plate pushes the corrugated paper to move, the corrugated paper will shake up and down, so that the corrugated paper can be more easily detached from the placement plate.
