When using honeycomb cardboard to process cartons, indentations will be made at the folding position to facilitate bending.

[0003] A search revealed a utility model patent with publication number CN215040687U, which discloses a honeycomb paperboard creasing device. The device comprises a conveyor platform, with a transverse and vertical pressure rollers rotatably connected to the top of the platform. The sidewalls of both rollers are rotatably connected to an adjustable bottom cylinder, within which an adjustable inner rod is connected. A drive member is located between each roller, driving the rotation of the adjustable bottom cylinder. The ends of the adjustable inner rod are fixedly connected to an outer pressure plate. The outer pressure plate of the transverse roller has a mounting slot in the middle, in which a creasing strip is mounted. The outer pressure plate of the vertical roller has a creasing ring on its outer wall. This patent facilitates adjustment and replacement, has a wide range of applications, and can produce multiple creasing effects simultaneously, saving time and improving efficiency.
