By utilizing the cooperation between the pressing roller 116 and the corrugated cardboard, indentations of different depths can be pressed together.

[0039] Secondly, when the direction of the corrugated cardboard needs to be changed, the drive motor 205 is started to drive the roller 206 to rotate, and the roller 206 is used to drive the cylinder 207 to rotate. The cylinder 207 and the groove wheel 208 cooperate to achieve the bottom plate 210 rotating only 90 degrees each time to change the direction of the corrugated cardboard.
