The equipment is huge, the height of a plant is required to be higher, and the equipment cannot be applied to the plant with the limited installation height. Meanwhile, equipment maintenance is dangerous due to the fact that installation space is high. Meanwhile, in order to improve the working efficiency of the folding paperboard equipment, a mode of improving the swing speed is often adopted. However, because the flexibility of the paperboard material is limited, redundant creases can be generated in the high-speed swing process, so that the folding quality of the paperboard is reduced.
