Paper feeding mechanism and paper file processing equipment with paper feeding mechanism

Abstract

The invention relates to a paper feeding mechanism and a paper file processing equipment with the paper feeding mechanism, in particular to a paper dividing opening used for limiting passing of a single piece of paper. The paper dividing opening comprises a guiding part and an elastic first blocking part, the guiding part comprises a guiding face, the guiding face is correspondingly arranged on the advancing path of paper, the guiding face is used for guiding the paper in contact with the guiding face to be more deviated to the first blocking part and enabling the first blocking part to deformunder the pressure of the paper, so that the first blocking part continuously applies downward pressure to the paper which continuously advances, the frictional resistance borne by the paper when thepaper passes through the paper dividing opening is further increased, and only a single piece of paper which is in direct contact with a paper conveying roller and has the maximum kinetic energy canovercome the frictional resistance to pass through the paper dividing opening.

Description

technical field [0001] The invention relates to a paper feeding mechanism and paper file processing equipment with the paper feeding mechanism, in particular to the improvement of the paper separating structure. Background technique [0002] Document processing equipment such as printers, fax machines, and scanners all have a paper feed mechanism to sequentially transport stacked recording paper to the work area. In this process, in order to prevent double-feeding, that is, two or more sheets of paper are sent in at the same time during paper feeding, a paper separation structure is usually provided, such as Figure 8 In the traditional paper feeding mechanism shown, the paper feeding rubber roller 103 drives the first recording paper 104 forward by its rolling, and the second recording paper 105 is also pushed forward by the frictional force generated when the first recording paper 104 advances. Driven by the front, a first limiter 100 and a second limiter 101 are provided ...

Problems solved by technology

[0003] However, this structure of paper separation by limiting the height of the paper feed is often unstable. On the one hand, it is affected by the dimensional tolerance of the parts, and on the other hand, it is affected by the tolerance of the machine assembly. There are many sources of error, resulting in the height of the paper separation port. It is very ideal to meet the requirements; and the smaller the thickness of the paper, the smaller the height of the required paper separation port, and the higher the precision requirements for the parts, which directly reflects the increase in machine production costs and the decrease in yield.
