Cigarette detection mechanism with multiple stations

The utility model discloses a cigarette detection mechanism with multiple stations, which relates to the technical field of cigarette processing and comprises a support plate, a negative pressure adsorption roller group is mounted on the surface of the support plate, and a plurality of groups of cigarette pipes are adsorbed on local surfaces of the negative pressure adsorption roller group. A first detection assembly is connected to the side face of the supporting plate and located outside the conveying starting end of the negative pressure adsorption roller set, a plurality of second detection assemblies are connected to the top and the bottom of the side face of the supporting plate, the multiple sets of cigarette branch pipes are conveyed in an S-shaped route through the negative pressure adsorption roller set, and the angle of each set of cigarette branch pipes is discontinuously changed in the conveying process. The first light source is used for supplementing light, the first CCD camera is used for dete
