The invention relates to a rotating wheel cigarette packet tracking and sampling realization method of a cigarette packer, which is characterized by comprising the following steps: firstly, 40 mould boxes of a cigarette group conveying belt of a packer rotating wheel inlet are numbered, and one side of the conveying belt is provided with a sensor which can only sense the No. 1 mould box; secondly, the mould boxes on the 1 to 8 rotating wheels are numbered, and a corresponding relation between the mould boxes and sampling holes on the rotating wheels are established in a computer; thirdly, a set of sampling and cigarette-picking devices is arranged on the last rotating wheel; fourthly, the original coder or a newly installed coder of a machine is used as a foundation of calculating machineperiodicity; after the sensor senses the No. 1 mould box, the rotating wheel rotates one mould box position, and the coder rotates a circle; when the coder rotates a circle, the calculating machine obtains a counting signal; finally, the specific machine cycle of the action of an eliminating device is calculated according to the position of a sampling box, and the cigarettes can be automatically eliminated and can be manually detected. The invention is beneficial to realizing sampling with equal probability and quickly determining the fault positions of the machine.
