The invention discloses a cigarette packet sampler, relates to an automatic sampler for detecting the density, humidity and other indexes of the cigarette packet, which belongs to field of tobacco machinery. The invention provides a cigarette packet sampler which exerts a short-term pressure onto the top of the cigarette packet to avoid the lifting of the cigarette and the damage at the top layer when a sampling rod withdraws. The cigarette packet sampler comprises a machine frame, a cigarette packet transmission device, and a sampling device, wherein, the cigarette packet transmission device is provided with a cigarette packet sampling stay position, the sampling device comprises a driving oil cylinder, a main pressing head, the sampling rod, and a damping pressing packet device, the damping pressing packet device comprises a damping mechanism, and a follow-up pressing plate supported by the damping mechanism; the follow-up pressing plate is arranged above the cigarette packet stay position on the cigarette packet transmission device, and the position on follow-up pressing plate which corresponds to the position of the sampling rod in the sampling device is provided with a through hole which leads the sampling rod to pass through freely. The invention has advantages that: the structure is simple, and the sampling efficiency can be greatly increased.
