[0036] Brief description of the usage process:

[0037] Process 1, cardboard conveying: The operator starts the cardboard conveyor 2 to convey the cardboard that has not been folded into a carton to the tail end.

[0038] Process 2, cardboard suction: start the cardboard collection conveyor (4) and the vacuum suction cup (5), and suck the cardboard at the tail end of the cardboard conveyor 2 through the vacuum suction cup (5). The sucked cardboard is conveyed to the top of the scissor lift (3) through the cardboard collection conveyor (4). The vacuum suction cup (5) is controlled to release the suction force on the cardboard, so that the cardboard falls steadily onto the scissor lift (3).

[0039] Process three, cardboard pushing: after the cardboard falls onto the scissor lift (3), the first hydraulic cylinder 601 is activated to control the movement of the push plate 602 to push the cardboard to a neat state to ensure the stacking effect.

[0040] Process 4: Cardboard stacking is stable: infrared rays are emitted by the infrared transmitter (7) and cooperated with the infrared receiver (8) to monitor the cardboard stacking height. When the cardboard stacking height reaches the infrared blocking position, the infrared receiver (8) does not receive a signal, triggering the scissor lift (3) to automatically descend. When the infrared receiver (8) receives a signal again, the scissor lift (3) stops descending, maintaining the distance between the cardboard stacking position and the vacuum suction cup (5), ensuring the cardboard position is stable when falling, and preventing deviation.

[0041] Through the operations of process one, process two, process three and process four, the cardboards of the unfolded cartons can be automatically conveyed and neatly stacked.
