无版烫印设备烫印头升降机构研究

摘要

无版烫印设备中的烫印头升降机构控制烫印头与烫印箔及承印物接触并适时调节压力，是无版烫印的关键部件。为了解决对烫印头压力检测的问题，采用一种优化的压力检测方法，保证了检测的精度、一致性和稳定性。同时，针对无版烫印设备承印物范围广、烫印压力变化范围大的问题，运用SolidWorks Simulation软件，对烫印头升降装置进行了有限元静力学分析，提出了结构改进方案。结果表明：该方案可有效减小烫印头与烫印头安装板螺钉连接处的应力。%The lifting mechanism controls the movement and the pressure of printing head to the foil belt and substrates, it is the key components of the digital hot stamping equipment. For the pressure detection of printing head, a kind of optimized method is used to ensure the accuracy, consistency and stability of pressure detect. Meanwhile, in order to guarantee the application of wide range of stamping pressure caused by the variation of substrates, this research uses SolidWorks Simulation software to do the finite element static analysis for the printing head lifting mechanism, a kind of structure improvement is proposed to reduce the stress of the bolted joint of printing head and the mounting plate effectively.
