[0016] The above technical solution of the utility model has the following beneficial technical effects:

[0017] The cardboard is placed on the conveyor belt, which continuously transports the cardboard and contacts the creasing disk first for creasing treatment. After creasing, the cardboard passes through the suction tube, which is driven to rotate. The rotation of the suction tube drives the exhaust bucket and the fan blades to rotate. The rotation of the fan blades extracts gas from the inside of the suction tube. The air pressure inside the suction tube decreases, and the waste chips on the cardboard are sucked through the suction holes, thereby achieving the effect of sucking the waste chips. The threaded groove is provided to level the support plate and increase the molding quality. BRIEF DESCRIPTION OF THE DRAWINGS
