[0029] Working principle:

[0030] When using the cardboard cutting machine of the utility model, the cardboard raw material is laid flat on the support plate 202, and the cardboard raw material enters between the active roller 201 and the pressing roller 203. The active roller 201 rotates under the drive of external force, and the pressing roller 203 is lifted upward by the cardboard raw material according to the thickness of the cardboard raw material. The pressing roller 203 presses the cardboard raw material against the active roller 201 under the action of its own gravity, so that the active roller 201 can drive the cardboard raw material to move forward. When the cardboard raw material reaches the position where it needs to be cut, the external force driving the active roller 201 to rotate is stopped, and the air is controlled to The output end of the cylinder 401 extends, and the output end of the cylinder 401 drives the pressure bar 402 to move downward to press the paperboard material onto the support plate 202, and then the motor 305 is controlled to start, and the output end of the motor 305 drives the driving pulley 302 to rotate, and the driving pulley 302 drives the driven pulley 303 to rotate through the belt 304, and the belt 304 drives the slider 307 to slide along the guide rail 306 from one end to the other end of the guide rail 306. During the sliding process of the slider 307, the circular cutter 308 rolls along the edge of the support plate 202, thereby cutting the paperboard material into paper pieces;

[0031] Then the output end of the cylinder 401 is controlled to contract, and the output end of the cylinder 401 drives the pressure strip 402 to move upward and reset. The external force drives the active roller 201 to continue to rotate and drive the subsequent cardboard material to continue to move forward. After reaching the position where cutting is required again, the active roller 201 stops again, and the cylinder 401 drives the pressure strip 402 again to press the cardboard material tightly against the support plate 202. Then the motor 305 is controlled to start reverse rotation, and the belt 304 drives the slider 307 and the circular cutter 308 to slide along the guide rail 306 to return to the initial position. During the returning process, the circular cutter 308 cooperates with the edge of the support plate 202 to cut the cardboard material into paper pieces. Repeating the above operations can quickly cut the cardboard material into multiple paper pieces of the required size.
