摘　　要：复印机的卡纸现象是影响复印机复印速度的主要因素,卡纸问题也存在于传真机、ATMs、冲印机等介质传送系统中。为了提高复印机进纸单元中纸张位置的准确性,研究了仅在重力作用下纸张进给过程中在纸道出口处的无约束动态变形。在Recury Dyn仿真软件中建立纸张通过纸道出口的运动模型,通过仿真分析不同速度对纸张变形的影响。结果表明,进给辊轮角速度由70 rad/s增加到130 rad/s时,纸张的弯曲变形量随着进给速度的增加而减小,纸张下降高度由62.8 mm减小到22.5 mm。通过调整纸张进给速度改变纸张端部的运动位置,为纸张能在进给过程中准确到达预定位置提供设计依据。Paper jam is the main factor effects the copy velocity and this problem also exists in media transfer system such as fax,ATMs,film developed machines,etc. In order to improve the accuracy of paper location in the feeding unit,study of unconstrained dynamic of paper under feeding process was performed. The paper motion model through the exit was built in Recury Dyn software. The impact of velocity on paper deformation was analyzed. When the rolling angle increases from 70 rad / s to130 rad / s,the dynamic deformation decreases with feeding speed,at the meanwhile,the height decreases from 62. 8 mm to 22. 5 mm. Adjusting the terminal motion location through paper feeding speed can provide design evidence for accurate pre-location in paper feeding process.
