Considering solution for existing nut packing machines on the market with the problems, including non-multifunction, high demanding in area occupation and human labor, a rotary multi-station automatic nut packing machine was designed. The machine combined the function of collecting quantitative and bagging the nuts, sealing with thermoplastic plastics, packing paper-bag and automatic sealing of the box. The machine mainly consisted of three systems, i.e., the feeding system with rotary controllable quantitative mechanism, the bagging system of catching and opening bags, bagging, sealing of the bags and the packing, and the sealing system for the boxes. It was verified that 720 bags (360 kg) of nuts could be packed using this machine in an hour, and the nut loss rate was less than 2%.
