Among them, corrugated boxes are made of corrugated cardboard after printing, slotting, creasing, nailing or gluing. They have the advantages of protecting goods, facilitating warehousing and transportation, beautifying goods, and being green and environmentally friendly.

[0003] In the related art, during the production process of corrugated paperboard, the staff first prints the finished paperboard through a printing machine. After printing the pattern on the surface of the paperboard, the staff slots the printed paperboard through a slotting machine, so that six slots are opened on the paperboard to facilitate creasing the paperboard. After that, the staff creases the slotted paperboard through the creasing machine, and then the staff nails or glues the creasing paperboard through a nailing machine or a gluer, thereby forming a finished corrugated paperboard.

[0004] With respect to the above-mentioned related technologies, the inventor believes that after printing the cardboard, workers need to collect it and carry it to a slotting machine for slotting, and then carry the slotted cardboard to a creasing machine for creasing, which increases the labor intensity of the workers.
