The invention discloses cigarette filter online flavoring molding equipment, and specifically relates to the technical field of cigarette processing. The cigarette filter online flavoring molding equipment is characterized in that a flavor spraying device, an adjusting assembly, a cloth cutting assembly and a tobacco shred coiling device are designed, the amount of flavor liquid adsorbed by non-woven cloth can be adjusted conveniently through control of a liquid spraying tube, and liquid sprayed from a liquid spraying head is in the form of mist, so that the flavor can be fully attached to thenon-woven cloth, and fragrance sheets are more fragrant. During implementation, the non-woven cloth is conveyed into a slicing device through an adjusting wheel and a steering wheel, the non-woven cloth with flavor can be cut to a required length more conveniently through control of the slicing frequency of a slicing tool and the speed of a crawler belt, and filter tobacco shreds, the non-woven cloth and filter sticks are conveyed into the tobacco shred coiling device coiling device through the adjusting assembly to be molded integrally by coiling, so that the flavoring effect can be kept constant and even improved without the need of controlling the speed of the non-woven cloth and filter stick adjusting assembly; the operation is convenient; meanwhile the cigarette filter processing project becomes easier.
