The invention provides a tobacco bale group intermittent motion conveying system comprising a motor transmission module, a roller convey module, and tobacco bale group brake modules; the tobacco bales are driven by the motor transmission module and the roller convey module so as to move along a track; the tobacco bale group brake modules arranged on two sides of the track can use intermittence motions to clamp or loosen the tobacco bale group; the tobacco bale group brake module at least comprises forming plates, an airbag bottom cavity, and an airbag sheet; the forming plate is arranged in the track side and seals the airbag bottom cavity; the airbag sheet is arranged in the airbag bottom cavity; the airbag bottom cavity is connected with an air supply pipe and a fast exhaust path; the forming plate is provided with airbag forming holes; when the airbag sheet is swelled, partial the airbag sheet extrudes outside the airbag forming holes so as to make contacts with tobacco bales; the brake modules clamp the tobacco bales, so rigid impact is converted into soft impact, thus causing less damages on tobacco bale end faces. The tobacco bale group intermittent motion conveying system is simple in structure, stable in operation, low in fault rate, can satisfy cigarette production technology requirements, and thus providing high industry utilization values.
