Background Along with the improvement of the health and harm reduction requirements of the tobacco industry, the addition of natural plant particles (such as herbal extracts, plant fibers and the like) into cigarette filters becomes an important technical direction. The particles can reduce harmful components in smoke through adsorption or slow release function, and simultaneously endow special fragrance to cigarettes. However, the prior art has certain technical defects: Firstly, the traditional vibrating screen only relies on horizontal vibration, so that the screening efficiency of light or wet plant particles is low, meshes are easy to be blocked, unqualified particles are mixed into a forming link, and the air permeability of the filter tip is affected; Second, existing roll-in molding machines often employ continuously rotating filling rolls, lacking an intermittent compaction mechanism. The particles are not fully compacted after being filled into the cavity, the density is low after being molded, and the particles are easy to crush in the filling process of the filter tip, so that the smoke resistance of the cigarette is fluctuated; Third, conventional curing relies on an external hot air oven, which is slow in heat transfer, needs long-time heating to shape, and is high in energy consumption and easy to cause activity loss on thermosensitive plant components (such as volatile oil).
