[0002] A paper cutting machine generally includes a longitudinal paper cutting module to cut longitudinal openings in corrugated paper to cut out appropriate paper shapes for assembling into corrugated cartons.

[0003] The existing longitudinal paper cutting module generally includes two longitudinal cutting units. The longitudinal cutting unit includes a mounting seat and a longitudinal cutting knife rotatably mounted in the middle of the mounting seat. The longitudinal cutting knife is installed in the middle of the mounting seat. Due to the size limitation of the mounting seat itself, the minimum distance between the two longitudinal cutting knives on the two longitudinal cutting units is relatively large, making it difficult to cut out narrow strips of paper. In addition, the longitudinal cutting knife is installed in the middle of the mounting seat. Due to the size limitation of the mounting seat itself, the maximum distance between the two longitudinal cutting knives on the two longitudinal cutting units is also relatively small.

[0004] In view of this, it is necessary to design a longitudinal paper cutting module and a paper cutting machine that are conducive to cutting out narrower and wider strips of paper.
