s4, after S3 is completed, aligning the fourth conveyor belt 231 and the third conveyor belt corresponding to the turnover mechanism 24, and moving the sheet bundle with the upside down to the fifth conveyor belt after separating from the fourth conveyor belt 231;

s5, moving the paperboard stacks to the bearing seat 45 after being separated from the fifth conveyor belt, and adjusting the height position of the bearing seat 45 to enable the paperboard stacks to be continuously stacked in the height direction;

specifically, after the paper boards with the right side facing upwards move onto the bearing seat 45, the height position of the bearing seat 45 is adjusted through the lifting driving assembly, so that the paper boards on the uppermost layer of the bearing seat 45 are approximately flush with the height of the fifth conveyor belt, and then the paper boards with the right side facing upwards move onto the paper boards with the right side facing upwards, so that the paper boards are stacked in a mode of aligning the paper boards with one pile and stacking the paper boards with the other pile; when the paper boards are stacked, the two arranging plates 51 are close to or far away from each other along the longitudinal direction so as to continuously flap the paper boards on the bearing seat 45, thereby achieving the purpose of arranging the paper boards.

In this embodiment, can pile up the cardboard pile with the form of positive pile and reverse pile through corrugated container board pile device, prevent to lead to the cardboard to take place to warp and warp the deformation because of depositing for a long time, guaranteed the quality of cardboard.

The corrugated board stacking device comprises two fourth conveying mechanisms, the turnover mechanism can turn over the paper board stack on one of the fourth conveying mechanisms, the paper board stack is turned over by the turnover mechanism, in the process that the paper board stack is turned over from the front side to the reverse side, and the other fourth conveying mechanism can convey the paper board stack from the front side to the reverse side, so that the conveying of the paper board stack in the form of one paper board stack and one paper board stack is realized. The in-process tilting mechanism has almost no downtime, and the processing efficiency of the processing line can be further improved while the utilization rate of the tilting mechanism is improved.

The bearing seat for bearing the paperboard stack can be displaced in the height direction, and no part is arranged at the bottom of the bearing seat, namely, the bearing seat can be directly contacted with the ground after the stacking is finished. This can raise the maximum stacking height of the cardboard.
