Automatic paper feeding mechanism for copying machine

Abstract

The invention discloses an automatic paper feeding mechanism for a copying machine and relates to the technical field of copying machines. The automatic paper feeding mechanism for the copying machinecomprises a U-shaped support, a paper feeding assembly, a guiding mechanism, baffles, connecting plates and a moving assembly. Through grooves are formed in opposite inner walls of the U-shaped support correspondingly. A transverse plate is fixedly installed on the inner bottom face of the U-shaped support. A pair of vertical plates are arranged on the surface of the transverse plate. An inverted-L-shaped plate is fixedly installed between the vertical plates. A pair of sliding rods are fixedly installed on the lower surface of a protruding portion of the inverted-L-shaped plate. A paper-pressing plate is slidingly connected to circumferential side faces of the pair of sliding rods. The paper feeding assembly comprises a rotary shaft. One end of the rotary shaft and the output shaft of afirst motor are fixedly installed. A paper feeding wheel is fixedly installed in the middle of the rotary shaft. According to the automatic paper feeding mechanism for the copying machine, through action of the U-shaped support, the paper feeding assembly, the guiding assembly, the baffles, the connecting plates and the moving assembly, the effects that limiting of paper of different width is conveniently conducted, paper is prevented from deviating in the conveying process, clamping of paper is reduced, and the copying quality is improved are achieved.

Description

technical field [0001] The invention belongs to the technical field of copiers, in particular to an automatic paper feeding mechanism for copiers. Background technique [0002] Copier is a common office supplies, widely used in various office fields; the paper feeding mechanism of the existing copier is relatively complex, with many parts and cumbersome, some parts will become loose after long-term use, resulting in failure when feeding paper. Offset, which affects the quality of the entire copy; and when copying paper of different widths, it is difficult to fix the position of the paper, resulting in movement during copying. [0003] To solve the above problems, the present invention regulates the position of the auxiliary wheels to limit the position of papers of different widths through the functions of the U-shaped bracket, the paper feeding assembly, the guide assembly, the baffle, the connecting plate and the movable assembly; The plate is fixedly installed, and the r...
