[0054] When the line type of the corrugated board needs to be changed, the line change drive module 212 drives the first rotating shaft 2111 to rotate slowly, and the pressing roller 2112 slowly switches the rolling line type member 2021 used for rolling the indentation line, thereby changing the line type;

[0055] After the creasing device is adjusted according to the size, thickness and line type of the corrugated cardboard, the corrugated cardboard is input from one end of the working chamber 11, and the creasing mechanism 20 cooperates with the supporting wheel mechanism 30. While the corrugated cardboard is transported to the other end of the working chamber 11, the corrugated cardboard is rolled, creasing and scored.
