The invention discloses an 
airflow type dust prevention device used for a tipping paper printing 
production line. The device comprises an air suction cylinder and blowing cylinders, a filter net is arranged on an outlet in the front end of the air suction cylinder, the 
tail is fixedly connected with a motor bin, a driving shaft of a motor is fixedly connected with a first 
turbofan blade, a hopperportion of the air suction cylinder communicates with pump machines and dust collection pipelines through air suction pipelines, the dust collection pipelines are provided with absorbing balls and buffer balls, the edges of the buffer balls communicate with dust sticking bags, semispherical packages are embedded on the blowing cylinders, and are connected with blocking balls through first rotatingshafts, and the blocking balls are provided with brushes; second 
turbofan blades and second rotating shafts are arranged on outlets in the front ends of the blowing cylinders; and the invention further provides a dust prevention method used for the tipping paper printing 
production line. The method comprises the steps of 
airflow type dust prevention device placing, running, cleaning, 
drying and the like. A vortex type 
air change structure is adopted, close-distance 
air change treatment of tipping paper can be achieved, dust can be absorbed through the dust sticking bags and the blocking balls, the dust sucking and sticking process is achieved, a cleaning and 
drying process is convenient, and site cleaning is achieved.
