Automatic paper feeding mechanism

Abstract

The utility model discloses a kind of paper automatic feeding mechanism, comprising: rack, the tray assembly is slidably arranged in the vertical direction in the rack, the tray assembly is driven by driving assembly, the top of the tray assembly is provided with negative pressure sucking disc, the outer side of the negative pressure sucking disc is provided with the anti-offset component for limiting the movement range of paper, the side of the negative pressure sucking disc is provided with vacuum air blowing plate mounted on the rack.The utility model drives tray assembly to move in vertical direction by driving assembly, so that the top surface of paper held on tray assembly is always located within a certain range from negative pressure sucking disc, ensure that the adsorption of the uppermost layer paper by negative pressure sucking disc, realize the self-adaptive adjustment of negative pressure sucking disc and tray assembly, so design, so that equipment can be loaded in large quantities at one time, reduce the time and labor cost of manual feeding, greatly improve production efficiency, while reducing the labor intensity of manual feeding.
