The invention discloses a cigarette feeding auxiliary device. The device comprises an upper cover, a lower cover, an adjustment mechanism and a control mechanism, wherein a cigarette cavity is formedby closing the upper cover and the lower cover; the adjusting mechanism is movably arranged in the upper cover plate in a penetrating mode; a limiting surface is arranged on the side, facing the lowercover plate, of the adjusting mechanism; the control mechanism is connected with the adjusting mechanism; and the control mechanism is used for controlling the adjusting mechanism to adjust the distance between the limiting surface and the lower cover plate after the upper cover plate and the lower cover plate are closed. According to the cigarette feeding auxiliary device, the filling and pre-clamping functions of cigarettes with different diameters such as conventional, medium and fine, the tedious steps of frequently replacing and adjusting gaskets according to the specification of the cigarettes in an existing operation process are simplified, and the working efficiency is improved.
