A sheet-striping, strip-gathering, rod-forming mechanism based on a cigarette filter forming machine is disclosed. The present invention relates to tobacco processing machines, and more particularly to a sheet-striping, strip-gathering, rod-forming mechanism based on a cigarette filter forming machine. The mechanism has a set of active roll release device for tobacco sheet roll additionally installed behind releasing rollers of the filter forming machine, which has a linear velocity of the released paper sheet matching a rod-forming linear velocity of the mechanism; a pair of releasing rollers near a pipe is replaced by stripping rollers replacing, with interrupted roller pattern along respective circumference; and a strip-guiding horn-shaped mouth is replaced by a tapered and collapsed horn-shaped mouth with an inlet diameter of 80-120mm. The mechanism is simple in structure and only requires moderate additional costs, while being suited for on-line stripping of tobacco sheet roll that is less tough and fragile, and effective in gathering and forming the strips.
