The invention discloses a fixed-point cutoff device for cigarette inner frame paper. The fixed-point cutoff device comprises an inner frame paper guide rail, a rear paper feeding wheel and a front paper feeding wheel. The shaft of the front paper feeding wheel and a shaft of the rear paper feeding wheel are each provided with a driving gear located on one side of the guide rail. An intermediate wheel is connected between the two driving gears. A lengthened input shaft stretching to the other side of the guide rail is mounted on the front driving gear, wherein a geneva wheel is mounted at the end, close to the corresponding driving gear, of the input shaft, and an internal-tooth gear is mounted on the part, between the geneva wheel and the corresponding driving gear, of the input shaft. A sleeve shaft is mounted on the part, on the other side of the guide rail, of the lengthened input shaft, and an inner frame paper differential compensation device is mounted at the outer end of the lengthened input shaft and the sleeve shaft. A shear type cutter is mounted at the paper discharge end of the guide rail outside the front paper feeding wheel. The fixed-point cutoff device has the advantages that fixed-point cutoff is accurate, and product quality is improved.
