[0021] When using the processing device, the staff first puts the blow-molded plastic bottles into the storage box 101, and then uses the driving motor 304 to drive the rotating cone 301 to rotate, so that the plastic bottles dropped into the storage box 101 are moved, and at the same time, the plurality of plastic bottles are moved by the shifting plate 102, so that the plastic bottles can enter the area separated by the plurality of partitions 303, thereby preventing the plastic bottles from piling up and avoiding the phenomenon of plastic sheets being crushed due to piling up, thereby further ensuring the integrity of the plastic bottles.

[0022] Since the rotating cone 301 is conical, when the plastic bottle falls into the area separated by the multiple partitions 303, the plastic bottle can automatically remain upright under the action of the inclined surface of the rotating cone 301, so that the plastic bottle can be subsequently transferred to the next production line.
