Wherein, the flake can be sanitary towel flake, and the stacking device 1 is arranged between a main machine of a production line of the sanitary towel flake and a middle packaging machine. The sanitary towel small pieces are piled into stacks by the piling device 1 and then sent into a packing machine for packing. The stacking device 1 stacks the sanitary towel small pieces from the feeding hole A to form a transverse piece stack.
Therefore, according to the stacking device 1 of the invention, when the feeding hole A is in the stacking of a group of stacks by the cooperation of the two circulating conveyors 102 on the stacking part and the stacking tables formed by the supporting plates 101, the stacks move downwards, new stacking tables are formed, and chips can be continuously stacked on the new stacking tables, so that the equipment does not need to be stopped, the full automation of the packaging equipment is realized, and the packaging efficiency is improved.
Referring to fig. 1 and 2, in some examples, the conveying section includes a negative pressure conveyor 202 and a waste discharging mechanism 203 that are horizontally disposed, and the bottom surface of the negative pressure conveyor 202 is a conveying surface.

Then, a plurality of pallets 101 are vertically fixed on the conveyor belt 1024, and two pallets 101 on the same horizontal plane and on opposite sides of the two conveyor belts 1024 on the two-cycle conveyor 102 can support the stack, whereby the stacking table can follow the movement while the conveyor belt 1024 is circularly moved, so that the stacking table can follow the increase in the number of sheets to perform the downward movement to complete the stacking operation, move the stack to the discharge port B, and form a new stacking table at the feed port a. 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 sliding blocks, the guide rails and the adjusting knob, so that the adjusting knob is adjusted to enable the sliding blocks to slide on the guide rails to adjust the distance between the two supporting 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.
