Description

Technical Field

[0001] The utility model relates to the technical field of cardboard cutting, in particular to a cardboard cutting machine. Background Art

[0002] Cardboard is the main raw material for making bank cards, subway cards, SIM cards and other cards. Cards are formed by stacking and pressing. The raw materials for making cardboard include polyvinyl chloride resin, colorant and additives. After cardboard is processed into paper, it needs to be cut to size using a cutting machine. When cutting cardboard, it is necessary to cut the cardboard paper by size first, and then cut the edge of the cardboard paper to improve the quality of the cardboard.

[0003] At present, in order to improve the cutting efficiency of paper jams, after the paper jams are processed, the paper jams are mostly stacked and cut by a paper jam cutter.
