The invention discloses an anti-scattering feeding device of a cigarette making machine. Left and right body side uppers are arranged at the upper end of a rack, a sealed skirt is arranged on the inner side of each body side upper, a conveying roll shaft is arranged at the middle upper end of the rack, a conveying roller is arranged on the inner side of the conveying roll shaft, a conveyor belt ismounted on the conveying roller, skirts are arranged on the left and right sides of the conveyor belt, a hairbrush roll shaft is arranged at the lower end of the conveyor belt, a hairbrush roll is arranged on the hairbrush roll shaft, a hairbrush is arranged on the hairbrush roll, and eccentric wheels are arranged on the left and right roll shafts of the hairbrush roller. A conventional panel conveyor belt equipment for the machine is transformed to a novel conveyor belt provided with a stripping skirt, the edge gap of the conveyor belt is sealed by the sealed skirt on the side upper of the body, and the hairbrush mechanism on the head cleans and the eccentric vibrating wheel shakes, so that cut tobacco materials attached to the conveyor belt are cleaned thoroughly and vibrated to fall and recover, and therefore, leakage of the materials is prevented effectively, and the loss of cut tobacco is reduced.
