The image obtaining unit 100 needs to be arranged at a position where images of aluminum foil paper and an inner frame paper on the cigarette packet can be obtained at the same time, and obtains the image according to an instruction sent by the PLC controller. After the actual image of the cigarette packet is obtained, the actual image information can be processed through the image processing unit, for example, image feature recognition, image algorithm and the like, and the colleague can compare the processed actual image with a preset standard image and output a comparison result; the defect judging unit judges whether the aluminum foil paper and the inner frame paper on the cigarette packet have defects according to the comparison result, if so, the PLC can control the cigarette packet removing mechanism to remove the cigarette packet with quality problems from the cigarette packet removing cigarette packaging line so as to ensure the quality state of the cigarette packet flowing out.
