Research on printing machinery design based on virtual prototype technology

Die-cutting machine is an important postpress processing equipment for surface decoration of printed matter. After speed of die-cutting machine increased, insufficient position time during the course of paper transferring is an important factor constraining die-cutting accurate improvement. For original shortcoming about paper-transferring mechanism design, performance of new paper-transferring mechanism may be predicted based on virtual prototype technology. By solidworks software, solid model of the paper-transferring mechanism can be established and the model can be imported into simulation analysis software ADAMS. With the mechanism simulated and the performance tested, the maximum positioning error of the paper-transferring mechanism at high-speed is 0.01 mm that it is far lower than the present error, so the design can meet the requirements of the machine. By applying virtual design method, the performance of the mechanism will be designed, analyzed and evaluated in early design in order to set and optimize prototype parameters. Thus the risk and the development cycle of new product exploitation will be reduced and the product performance will be increased.
