[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of corrugated core paper interlayer and one layer of cardboard. It has high mechanical strength and can withstand collisions and falls during transportation. Cartons or boxes made of corrugated cardboard are widely used in social life. In order to facilitate the use of corrugated boxes and corrugated boxes, it is often necessary to punch holes in the corrugated cardboard, so a corrugated cardboard punching machine is needed.

[0003] The prior art discloses a corrugated cardboard punching device with a publication number of CN217669700U, which includes a chassis, an elastic bracket and a chip collecting bucket. A fan is installed on one side of the chassis, a controller is installed on the back side of the chassis through a bracket, an electric lifting frame is installed on the back side of the chassis through bolts, a cross arm is installed on the top of the electric lifting frame, a motor is installed on the top front end of the cross arm through bolts, a punching sleeve is installed on the output end of the motor, three groups of elastic brackets are installed around the bottom front end of the cross arm, and a protective pad is installed at the bottom of the elastic bracket. The utility model installs a protective pad at the bottom of the elastic bracket. When punching, the protective pad will contact the corrugated cardboard before the punching sleeve under the action of the elastic bracket. When the punching sleeve is pulled out, the protective pad can be used to limit the corrugated cardboard to avoid deformation at the punching position of the corrugated cardboard, thereby ensuring the processing quality of the corrugated cardboard.

[0004] The punching head used in the above utility model includes a punching sleeve and a tooth groove, and is driven to rotate by a motor to realize the punching processing operation on the corrugated cardboard.
