Abstract:

In order to reduce the design cost and manufacturing difficulty of complicated textile machinery and equipment, 3D printing technology was applied to develop scale medel of its function module. Digital prototype link beating-up and shedding mechanism was designed, and the model was translated into STL format for slice processing and model package calculating, and then the optimal parameters of its 3D printing process were confirmed by analyzing and comparing some factors, such as placement directionof the model, material cosage and molding time. Scale model of the mechanism was manufactured by industrial-grade 3D printer (Dimension Elite) , and a control platform of electromechanical integration system of it was successfully developed C langrage and single chip microcomputer. The technology advantages of 3D printing in one-step shapeng not only reduce development costs and experimental difficulty of physical prototype, but also provide a new idea and reference for model display, mechanism validation, performance evaluation and reliability analysis of the textile machinery and equipment.

Key words: 3D printing, textile machinery, bar beating-up and shedding mechanism scale model
