The small sanitary towel pieces are stacked into a stack by the stacking device 1 and then sent to a packaging machine for packaging. The stack stacked by the stacking device 1 is formed by stacking the small pieces of the sanitary napkins on the stacking platform from the feed opening A to form a transverse stack.

Therefore, according to the stacking device 1 of the present invention, the cooperation of the stacking platforms formed by the two-cycle conveyor 102 and the plurality of pallets 101 on the stacking portion enables the stacks to move down when the feed port a finishes stacking of a group of stacks, a new stacking platform is formed, the sheets can be continuously stacked on the new stacking platform, the equipment does not need to stop, the full automation of the packaging equipment is realized, and the packaging efficiency is improved.

With reference to fig. 1 and 2, in some examples, the conveying portion includes a horizontally disposed negative pressure conveyor 202 and a waste discharge mechanism 203, and a bottom surface of the negative pressure conveyor 202 is a conveying surface.

The circulating movement of the conveyor belt 1024 is driven by a transmission structure of a synchronous pulley, a synchronous belt and a motor connected to the driving roller 1022.

In addition, the two supports 1021 are assembled together through the slider, the guide rail and the adjusting knob, so that the adjusting knob enables the slider to slide on the guide rail and can adjust the distance between the two support plates 101 on the stacking table according to the size of the stack, and the stacking table is suitable for the sizes of various stacks.

In some examples, the discharging part includes a moving bracket 301 and a moving driver 302, the moving bracket 301 is disposed at the discharging hole B to receive the stack on the stacking table, and the moving driver 302 is connected to the moving bracket 301 to drive the moving bracket 301 to move to transfer the stack to the middle packing machine.
