[0030] The working principle of this utility model is as follows: After the paper cups are produced by the paper cup forming machine, they are conveyed by the feeding conveyor mechanism 1 and positioned by the positioning mechanism 2, so that the paper cups are regularly arranged between the positioning plate body 21 and the limiting plate 24. Then, the suction mechanism 3 is activated, the electric telescopic rod 64 drives the suction head 54 to move down, the air pump 51 is activated to pump air, and the suction head 54 sucks up multiple paper cups. Then, the electric telescopic rod 64 drives the paper cups to rise, and the moving component 7 moves the paper cups to the top of a stacking mechanism 4. Then, the electric telescopic rod 64 moves down, the air pump 51 is turned off, and the paper cups fall into the stacking hole 42. Then, the moving component 7 drives the suction mechanism 3 to return, and the suction operation is repeated. Then, it moves to the top of the stacking mechanism 4 again to stack the paper cups until the paper cups are stacked to a specified height. After the last paper cup falls on the already stacked paper cups, the electric telescopic rod 64 is activated to move down and press down on the paper cups. This improves the tightness of the connection between paper cups. Since the lifting mechanism 6 is equipped with a shock-absorbing component, it can slowly apply pressure to the paper cups to avoid damage caused by excessive pressure. Then, the electric telescopic rod 64 moves upward, and the suction mechanism 3 moves to the initial position to continue suctioning the paper cups. The paper cups are placed on another stacking mechanism 4 via the moving component 7. At the same time, the cylinder 46 is activated, which pushes the stacking platform 41 with stacked paper cups to move above the unloading conveyor 9. The unloading conveyor 9 moves intermittently. When the unloading conveyor belt 92 stops moving, the second motor 45 is activated. The second motor 45 drives the two baffles 43 to open, and the paper cups fall onto the positioning post 96 of the unloading conveyor belt 92, completing the unloading of the paper cups. After that, the cylinder 46 drives the stacking platform 41 back to the initial position to wait for the next round of paper cup stacking operation. Setting up two stacking mechanisms 4 can save the time of paper cup stacking and unloading, and improve production efficiency.
