Abstract
The invention discloses a paper feeding mechanism. The mechanism comprises: a shell, a first rotating shaft and a second rotating shaft, wherein the first rotating shaft and the second rotating shaft are installed in the shell. The shell comprises: a base, a first sidewall, a second sidewall, a first end wall and a second end wall. The first end wall is provided with a plurality of installing holes. The first sidewall is provided with a first inclined hole and a second inclined hole. The second sidewall is provided with a third inclined hole and a fourth inclined hole. The first rotating shaft is installed in the first inclined hole and the third inclined hole. The second rotating shaft is installed in the second inclined hole and the fourth inclined hole. Two ends of the first rotating shaft and two ends of the second rotating shaft are provided with springs respectively. The paper feeding mechanism is installed on a paper inlet of a printer. The printing paper should passes through the paper feeding mechanism before enters into the printer. When the printing paper is transmitted to the two rotating shafts, the rotating shafts press the paper evenly. After being pressed for two times, the paper becomes flat when entering into the printer. Therefore, a printer paper jam phenomenon caused by paper wrinkling can be effectively prevented.
