Then the conveying component 3 sends the cardboard to the unloading tray 502 of the unloading component 5. At the beginning, the bottom surface of the unloading tray 502 used to carry the cardboard is slightly lower than the position where the cardboard is sent out. When the cardboard on the unloading tray 502 gradually increases, the unloading tray 502 is driven to gradually move down by the lifting drive mechanism, so that all the cardboards can be smoothly received. The unloading tray can move down once at intervals, and each time it moves down a certain distance. The time interval for moving down can be set by degree. In addition, the work of the lifting drive mechanism can also be manually controlled by computer.
