[0002] A paper box cutting device is a specialized piece of equipment used to process paper packaging materials. Its main function is to precisely cut materials such as cardboard and paperboard using mechanical or CNC methods to produce paper boxes or packaging cartons that meet specific requirements. This device is widely used in the packaging, printing, logistics, and food industries and is one of the core pieces of equipment in the paper box forming process.

[0003] Patent CN220808669U discloses a cardboard box cutting device. When the brake motor is running, it will cause the movable shaft to rotate through the rotating shaft. The rotation of the movable shaft will cause the circular block to move inside the connecting plate, thereby causing the two connecting plates to move towards each other. This will reduce the distance between the two movable plates, thus limiting the width of the cardboard and preventing the subsequent cardboard box production from being affected by the tilt of the cutting part. However, when using this cutting device, the cardboard is prone to bulging or displacement during the cutting process, which will affect the normal cutting process of the cardboard and reduce the cutting efficiency.
