Embodiment Construction
[0033] see figure 2 , the structure of an embodiment of the double-sided paper feeding mechanism of the present invention includes: a paper feeding roller unit 20, a damping transmission unit 30 and an electromagnetic clutch 40, wherein the damping transmission unit 30 and the electromagnetic clutch 40 are all connected to the power of the business machine Source connection, an implementation of the power source is usually composed of a motor and a transmission assembly (such as a gear). In an embodiment of the present invention, the power source system provides rotational power in a single direction, and the damping transmission unit of the present invention 30 and the electromagnetic clutch 40 are driven by the power source to rotate in opposite directions.
[0034] One embodiment of the paper feeding roller unit 20 includes a roller shaft 21, at least one driving roller 22 and a driven roller 23, the roller shaft 21 can drive the driving roller 22 to rotate, and then the d...

The invention discloses a two-surface paper advancing mechanism and a two-surface paper feeder. The two-surface paper advancing mechanism comprises a paper advancing roller unit, a damping transmission unit and an electromagnetic clutch, wherein the paper advancing roller unit has a roller shaft, a driving roller and a driven roller; the roller shaft drives the driving roller and links the driven roller to rotate for conveying papers; the damping transmission unit is respectively connected with a power source and the roller shaft, and has a damping transmission component connected with the roller shaft through coupling force, and enables the power source to drive the roller shaft to rotate towards a first direction; the electromagnetic clutch is respectively connected with the power source and the roller shaft, and is driven by the power source to rotate towards a second direction; the electromagnetic clutch is combined with or separated from the roller shaft; and the connecting force of connecting the electromagnetic clutch with the roller shaft is greater than the coupling force for connecting the damping transmission component with the roller shaft, so that the roller shaft can be driven to rotate towards the second direction when the electromagnetic clutch is connected with the roller shaft. The two-surface paper advancing mechanism can realize the two-surface paper advancing without changing the rotating direction of a motor or the power source, and can prevent the influence on other parts caused by reverse rotation.
Description
technical field [0001] The invention relates to a paper feeding mechanism of an office machine, in particular to a double-sided paper feeding mechanism capable of supporting double-sided paper feeding. Background technique [0002] In order to support the numerous and complicated clerical affairs in the modern industrial and commercial society, business machines have become one of the necessary equipment in modern offices, especially multi-functional business machines that integrate fax (Fax), scanning (Scanning) and printing (Print). Popular, in order to provide faster and more convenient document paper processing functions, the new generation of business machines are usually equipped with automatic document feeder (Automatic Document Feeder, ADF), which can automatically and continuously feed multiple sheets of paper into the business machine, based on environmental protection and For the purpose of making full use of paper, another duplex paper feeder that supports the do...
