Abstract
A front edge paper feeding mechanism of a multi-servo drive system is provided. Paper plate data are input to a servo control computer; a servo drive controls the working length of four paper feeding shafts so as to extend the paper feeding distance, i.e. the length of the paper plate is equal to the paper feeding distance of the paper feeding shafts, the paper feeding precision is subsequently improved and the paper plate pulling resistance of a paper feeding rubber roller is reduced. In addition, a pressure buffer area is arranged below an adjusting valve plate of a paper feeding box; when a fan starts absorbing wind, the pressures of pipe mouths in the buffer area are equal; the breadths of the paper plate are different, when the starting or closing of a valve needs to be adjusted, the pressure and the flow rate of the opened parts are equal, so the absorbing force generated by a paper feeding table top is also equal, and the accuracy of paper feeding is further ensured.
