Abstract: Unsatisfied with the loosening effect of traditional feeder, therefore a reconstituted tobacco feeder with automatic loosening function was designed, which was composed of a feeding belt, an automatic loosening device, a hopper and an elevating belt. Reconstituted tobacco was conveyed to the automatic loosening device via the feeding belt, the loosened tobacco entered hoper and was uniformly blended by elevating belt, which could be adjusted according to the flow of tobacco. The results of application showed that there was no obvious tobacco breakage, the loosen rate reached 99.7%, and the loosening effect of reconstituted tobacco and the blending of tobacco were improved.
