[0035] In the whole marking process, the transportation assembly first transports the carton board to the guide assembly, the guide assembly adjusts the distance between the guide rollers 17 according to the width of the carton board, and guides and positions the carton board. Then, the carton board enters the area of the marking assembly, the height adjusting assembly adjusts the height of the pressing roller 8 according to the thickness of the carton board, and the first motor 5 of the marking assembly drives the pressing roller 8 to perform the marking operation on the carton board. Each assembly cooperates with each other to realize efficient and accurate marking of carton boards of different thicknesses and widths. In addition, the framework composed of the side plate 1 and the top plate 2 and each moving assembly adopt a split structure, which is more convenient to install, maintain or replace the assembly, can be flexibly assembled and matched according to actual needs, and improves the use convenience of the equipment.
