Dynamics Simulation And Analysis For Paper Feeding Mechanism Of Office

Printers,copiers,fax machines,etc.is a kind of important office automation equipment. on the one hand, the equipment improve work efficiency, on the other hand, trouble,such as paper jamed and paper stacked ,influence users and manufacturers. Especially in the high-speed printing and double-sided copying, there are also serious vibration and noise with the paper feeding mechanism, thus affecting quality and speed of process.This research is mainly about the paper feeding process in the mechanism. Applying the creep rate theory and linear theory of Kallker, this study built mathematical analysis model for the contact force between the sheet and feed rollers, and derived its motion equation. In this study, we formed the dynamic equations by the relations of the interacting force between the sheet and rollers. After dividing the feeding process into two types and four steps, we also be able to get function of kinetic equation by applying RungeKutta method.By applying the RecurDyn, firstly, we analysised the deflection characteristics of the sheet, then built the dynamic model of the paper feeding mechanism and simulated paper feeding process in different conditions, Finally, from the results, conclusions were drew to discuss about the affects of normal forces, friction coefficients, and velocity difference of the rollers on the velocity stability of the paper sheet in various feeding speeds. By simulation analysis, we got the dynamic parameters that we cared about, which can provide reference data for its FEM calculation, fatigue evaluation and the affects of some important mechanical parameters on the dynamic behavior of the sheet during the feeding process.
