[0002] Corrugated cardboard is a widely used packaging cardboard. After being made into continuous sheets of corrugated cardboard, the existing corrugated cardboard is generally pressed and cut according to the required size, and finally made into corrugated cardboard of predetermined specifications. For this reason, the equipment for pressing the corrugated cardboard is an important part of the production of corrugated cardboard. In the existing corrugated cardboard pressing equipment, the corrugated cardboard is rolled and indented with a scoring line by a scoring mechanism, and then the corrugated cardboard is folded and formed according to this scoring line. Therefore, the accuracy and quality of pressing the scoring line have a very important influence on the folding and gluing (stapling) of the corrugated cardboard.

[0051] When the line type of the required scoring line of the corrugated board needs to be changed, the line change driving module 212 drives the first rotating shaft 2111 to rotate slowly, and the line type changing roller 2112 slowly switches the rolling line type member 2021 used for rolling the scoring line, thereby changing the line type;

[0052] 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.
