Taking the semi-finished rice dumplings which have been filled as the research object, the paper studied the mechanical folding and wrapping of rice dumplings. The basic functions and requirements of movements for folding and wrapping rice dumplings were analyzed, and the technical principles and process were studied. Based on the operational requirements of wrapping rice dumplings including lifting, pressing leaves, folding wings and wrapping horns, integrated technical solutions of folding and wrapping were researched and the choosing and designing of key actuators were discussed. Parametric design and optimization were conducted for the key mechanisms. Automatic folding and wrapping of rice dumplings was realized by mechanisms such as crank slider and pendulum block, and the design of automatic rice dumpling wrapping device was completed. In conclusion, a new automatic folding and wrapping process was proposed based on the traditional manual wrapping process, and the mechanism design was completed, which provided a reference and basis for the design and development of similar special wrapping methods and relevant mechanisms.
