Method for rapidly matching specifications of flattening disc and flattening groove of cigarette making machine for thin cigarettes

The invention discloses a method for rapidly matching specifications of a flattening disc and a flattening groove of a cigarette making machine for thin cigarettes. The method comprises the followingsteps: (1) determining a density mean value Tj of ends of a plurality of cigarette samples and a density mean value MJ of non-compaction sections of the cigarette samples according to the density of the thin cigarettes; (2) calculating a density distribution characteristic value Y of end sections of the thin cigarettes; (3) judging whether the Y value obtained by step (2) is in a range of (1.20, 1.30) or not; if the Y value is in the range of (1.20, 1.30), determining that the specifications of the flattening disc and the flattening groove of the cigarette making machine for the thin cigarettes are proper; when the Y value is closer to (1.20+1.30)/2, determining that the matching degree of the specifications of the flattening disc and the flattening groove of the cigarette making machine for the thin cigarettes, a
