A front-edge paper feeding device is applicable for automatically conveying a stack of cardboards one by one. During operation, the stack of cardboards is placed on a grid plate, and a control element is provided for controlling the grid plate to elevate and descend reciprocally. When the grid plate elevates, the cardboards are separated from a conveyor wheel. When the grid plate descends, the conveyor wheel is exposed, such that the conveyor wheel is in contact with the cardboard. A servomotor is provided for controlling intermittent rotations of the transmission shaft while driving the conveyor wheel, so that the conveyor wheel drives the cardboard to move in order to convey and output the cardboard smoothly. |
