The front end of the transfer plate 3 is fixedly connected with two groups of connecting blocks 639, and the two groups of connecting blocks 639 are rotatably connected with the front baffle frame 638. The insertion of the fork 5 will push the lower end of the front baffle frame 638, so that the front baffle frame 638 rotates and blocks the front of the transfer plate 3. In the process of moving the transfer plate 3, the corrugated cardboard 4 stacked on the transfer plate 3 can be prevented from falling, and the push of the front baffle frame 638 can make the corrugated cardboard 4 stacked on the transfer plate 3 more neatly.

[0042] When in use, the transfer plate 3 is placed at the output end of the transfer frame, and the bevel gear 1 605 and the bevel gear 2 626 are meshed with each other, then the corrugated cardboard 4 is placed on the transfer conveyor frame 1, and the corrugated cardboard 4 is transported to the specified position by the transfer conveyor frame 1, and the corrugated cardboard 4 moves on the transfer conveyor frame 1 until it moves below the downward pressure driving rubber roller 614. The downward pressure driving rubber roller 614 driven by the motor 604 can increase the thrust generated when the corrugated cardboard 4 moves, so that the corrugated cardboard 4 supports the short arm end of the driven plate 603 and pushes the driven plate 603 to move, until the rack 615 moves to mesh with the transmission gear 610 and drives the transmission gear 610 to rotate, thereby driving the bevel gear 1 605 and the bevel gear 2 626 to rotate, so as to make the prying plate on the transmission belt 2 630 When the prying plate 632 moves, and when the prying plate 632 near the side of the support plate 633 moves upward, it will push the support plate 633 to move downward, so that the stacking platform 627 on the support plate 633 falls into the next layer of the support plate 633, and as the driving spring 636 pulls the extrusion ring 634 to squeeze the support plate 633, the support plate 633 is quickly reset, and the stacking platform 627 can be supported by the next layer of the support plate 633. This reciprocating process can realize the stacking of corrugated cardboard 4, and can prevent the corrugated cardboard 4 from floating and failing to fall to the designated position due to the stacking height being too large. After the stacking of the corrugated cardboard 4 is completed, the fork 5 of the forklift 2 is inserted under the transfer plate 3, and as the fork 5 is inserted, the lower end of the front baffle frame 638 is pushed, so that the front baffle frame 638 rotates to block the front of the transfer plate 3.
