[0002] Logistics includes the transportation, distribution, warehousing, packaging, handling, loading and unloading, circulation and processing of goods as well as related logistics information.

[0003] Usually after the goods are packed, they are delivered to different places, so they need to be sorted. The goods in the same place are sorted together and then they can be delivered.

[0004] Usually, a slider sorter or a cross-belt sorter is used in the existing sorting system to sort these goods.

[0022] The lifting member and the cleaning structure are driven by the lateral moving member to move to the top of the bidirectional balance wheel structure, so that multiple cleaning parts correspond to multiple circular holes. Then the lifting member drives the cleaning structure to descend, and the arc-shaped brush moves into the circular hole. The arc-shaped bristles on the arc-shaped brush contact the inner wall of the circular hole. At the same time, the strip bristles on the strip brush contact the rotating wheel.
