The work aims to design an automatic bagging system for cheese, in order to realize the automatic bagging and improve the packaging efficiency. The mechanical structure of this automatic bagging system was designed based on the process flow of manually loading cheeses into woven bag. The bagging system could realize three functions: supplying bags, opening bags and bagging functions. Three-dimension modeling of each function module of the bagging system was conducted using SolidWorks software. The virtual system assembly was conducted. The cheese automatic bagging system could achieve the packaging process that 3×4 cheeses were automatically loaded into woven bag. The system structure was simple and easy to operate. The application of cheese automatic bagging system greatly reduces the labor intensity of packaging workers and has important application value to the automatic packaging of cheeses.
