[0034] Referring to the accompanying drawings, the principle of this utility model is as follows: The paper stack 8 moves along the paper separating conveyor line and is blocked at the paper stop mechanism. The friction between the paper separating conveyor line and the bottom cardboard 9 of the paper stack causes the cardboard to separate from the paper stack and pass through the first paper exit gap. Then the cardboard passes through the second paper exit gap and is separated out. Under normal circumstances, only the bottom cardboard passes through the first paper exit gap. When the previous cardboard sticks to the bottom cardboard and passes through the first paper exit gap together, the previous cardboard will be restricted by the second paper exit gap and cannot pass through the second paper exit gap, thereby ensuring that a cardboard can be stably separated each time, resulting in better overall stability.
