This packaging production task is mainly completed by three machines, namely, the pallet making forming machine, the several grain (zongzi) dispenser and the cartoning machine. This is an organic combination of rare machines and production lines, and the tacit cooperation between them is enough to meet the complete packaging needs of Wufangzhai from material preparation to mixing and even cartoning. Among them, due to the large floor area of the pallet, Hengli Packaging adopts a more flexible supporting supply form, folding the packaging box to form a pallet, which effectively saves space and labor for production. As the core technical advantage of Hengli Packaging, the automated mixed counting packaging form also needs to face the identification and counting difficulties of irregular shape and large volume of zongzi. However, after a series of improvements in optimizing the internal structure, while keeping accurate counting, the entire production process is not only faster, but also safer, making the benefits significantly increased.
