[0003] As is known to all, cardboards need to go through the process of paper lamination during the production process, and after the paper lamination is completed, the cardboards generally need to be stacked in order to save storage space. The existing stacking method of cardboards requires first stacking a preset number of cardboards in a first direction, and then stacking a preset number of cardboards in a direction opposite to the first direction (a second direction) on top of the first bundle of cardboards, that is, stacking the preset number of cardboards in the positive and negative directions one front and one back.

In the actual working process, after the turning device turns the cardboard, the paper is pushed away from the turning device by the paper pushing mechanism, and the cardboard is pushed down and falls onto the paper receiving frame, and then the sliding device drives the paper receiving frame to slide toward the bottom of the frame, and then the paper is unloaded by hand; then the sliding device drives the paper receiving frame to slide toward the top of the frame, so that the paper receiving frame is close to the turning device to receive the paper. However, there are the following problems in such a paper receiving process: since the paper receiving frame is driven to move toward the bottom of the frame, even if the turning mechanism completes the turning of the paper, it must wait until the paper receiving frame is driven again and approaches the turning mechanism, and the paper pushing mechanism can continue to work so as to push the turned paper and drop it onto the paper receiving frame, which makes the paper receiving efficiency of the existing paper receiving mechanism low.
