When the first finger 71 continues to move down to reach the height of the second finger 81, the first finger 71 is horizontally drawn out by the first servo driving member 732, and the sheets stacked on the first finger 71 are transferred to the upper surface of the second finger 81; the first finger 71 is driven by the second servo driver to return to the waiting position to wait for the next insertion of the split stack. The second finger 81 continues to move down in accordance with the sheet folding speed under the control of the control means. When the number of stacked sheets reaches a set number, the insertion and stacking operation of the first finger 71 is triggered. The paper is repeatedly circulated, the machine does not need to be stopped in the production process, continuous automatic stacking production is realized, the production efficiency is greatly improved, and the guarantee is provided for realizing the automatic production of the paper.
