The aim of this study was to design a mechanism of label folding wrap. The parameters of the major execution module were designed based on the theory and the methods of the four-bar linkage design in combination with the AutoCAD assisted mapping. The structural model for the label folding wrapping mechanism was carried out using modeling module which was based on the software of SolidWorks. Aiming at rectangular paper label and specific requirement of wrapping, the design put forward the principle of label folding wrapping system. The parametric design of the key mechanism of label folding wrap was completed according to the minimum transmission angle theory. The structural model was accomplished to verify the feasibility of the mechanism. The mechanism of label folding wrap could be used to pack both rigid and flexible objects. This study provides a reliable theoretical guarantee for applying the label folding wrapping mechanism to the manufacturing.
