新型胶印机递纸吸嘴机构动态性能分析

为了满足胶印机高速生产时平稳输送纸张的要求,针对正处于研制的新型共轭凸轮递纸吸嘴机构进行了高速工况下的理论动态分析.在将递纸吸嘴机构看成是一个弹性系统的条件下,以动力学理论为基础,通过适当的假设,建立了机构的简化动力学模型及其运动微分方程.根据企业提供的基本数据运用数值算法,经过计算得出了机器在最高运行速度下机构的动态响应和动态运动误差.结果表明,在高速工况下这种具有几何封闭的递纸机构不能满足高速印刷机输纸的要求,可通过参数优化改进机构的设计.本研究可为高性能的印刷机研制提供参考.

Dynamic Analysis of a New Forwarder Sucker Mechanism

In order to meet requirements of paper-transfusion in high-speed production,dynamic analysis of high-speed state on forwarder sucker mechanism of conjugate cam in offset is made.The concise dynamic model and differential eguation of this mechanism based on dynamic theoretics and elasticity system are set up.According to basic data that the enterprise had provided and numerical arithmetic method,dynamic output and dynamic error in highest speed on offset are obtained.The result shows that this late-model forwarder sucker mechanism with close power can not stably feed papers in high-speed.Optimum parameters could improve the performance.This research provides reference for design and improvement of the mechanism.
