The invention discloses a suspension-type paper pressing ear breaking device. The suspension-type paper pressing ear breaking device is characterized in that the device comprises an upper paper pressing plate structure and a lower paper pressing plate structure; the upper paper pressing plate structure comprises an air cylinder, an upper floating plate, an upper fixing plate and upper paper pressing blocks; and the lower paper pressing plate structure comprises a lower floating plate, a lower fixing plate, a wallboard and lower paper pressing blocks. A working method includes the steps that the upper floating plate moves downwards along with the air cylinder, the position, where deformation is not required, of a cigarette label makes contact with the upper floating plate and the lower floating plate, and the cigarette label is fixed; the position, where deformation is required, of the cigarette label does not make contact with parts and is in a free state; and the position with deformation required makes contact with the upper paper pressing blocks and the lower paper pressing blocks in the ear breaking process so that deformation can happen. The suspension-type paper pressing ear breaking device and the working method thereof have the advantages that the effect that the cigarette label is not side-tipped or deflected in the ear breaking process can be guaranteed through the structure, the cigarette label is evenly stressed in the ear breaking process, and the phenomenon that the cigarette label and an upper plate and lower plate form dents to damage paper can be avoided; and meanwhile, greater deformation of the cigarette label can be achieved in the ear breaking process by the adoption of the fixing mode, and the ear breaking effect is made better.
