Centrifugal paper cutting mechanism

The utility model relates to the technical field of centrifugal paper production. The invention relates to a cutting mechanism, in particular to centrifugal paper. The device comprises a cutting machine, a frame, a dust collection roller, a suction pipe, a suction nozzle, an air suction pipe, a suction fan and a purification box, wherein the frame is fixedly connected to the top of the cutting machine, the dust collection roller is arranged at the top of the frame, the suction pipe is fixedly communicated to the bottom of the dust collection roller, the suction nozzle is fixedly communicated to the bottom of the suction pipe, and the suction fan is fixedly connected to one side of the inner wall of the cutting machine through a supporting plate. When the suction fan works, certain adsorption force can be generated; instant vacuum is formed in the dust collection roller through the air suction pipe; the air pressure in the dust collection roller is greatly lower than the external air pressure; under the action
