The automatic bag sorting machine can be used alone in the production, or can be docked with the cartoning machine, to complete the whole process of arranging irregularly piled materials from centralised to decentralised and then to sequential placement. After the irregularly piled materials are poured into the storage bin, the bin conveyor belt moves and conveys the materials to the low-speed rollers. Through the operation of low, medium and high speed rollers, the materials will be sent out of the bagging machine one by one in sequence. The materials sent out according to the packaging needs of the form, order or stacked into the cartoning machine conveyor to complete the next process of cartoning process.
