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%.%针对现有的干果包装机多为功能单一、占地面积大、对人工依赖程度高等问题,设计一种旋转式多工位自动干果包装机,该机器集干果的定量收集、装袋、热塑封袋、纸袋整齐装箱、自动封箱等功能于一体.该机器结构紧凑,功能齐全,主要包括3个系统,即:旋转式可控定量投料系统,集抓袋、开袋、装袋、封袋于一体的打包系统,装箱、封箱系统.经实验验证,该机器每小时能包装720袋(合360 kg)干果,损失率≤2%.
