Objective The automatic bagging equipment for rotary cement packing machine was developed. Methods According to the steps of manual operation, the automatic bagging equipment had the functions of automatic bag feeding, fetching and clipping. The mechanism structures of equipment were designed by using SolidWorks software. Results On the basis of parameter optimizations, the three-dimensional mechanism structures of the modules were designed, and virtual system assembly was conducted. It turned out the design of automatic bagging equipment conformed to the equipment requirements. Conclusion Compared to manual bagging, the equipment could reduce the labor intensity and protect the personal safety, and realize the complete automation of cement packaging.
