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.
Description
Technical field
The present invention relates to a kind of paper advance mechanism.
Background technology
In the prior art; people often can run into the phenomenon of paperboard when using printer; the generation of this kind paper jam phenomenon is normally because printing paper compares fold; people usually need to be with the apparatus lid opening of printer after running into paper jam phenomenon; the paper that then will be stuck in the inside is taken out; then could continue to use printer, this greatly reduces people's operating efficiency.
Therefore, be necessary to provide a kind of paper advance mechanism that solves the problems of the technologies described above.
Summary of the invention
Technical problem to be solved by this invention is: a kind of paper advance mechanism that prevents paperboard is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of paper advance mechanism, it comprises: housing and be installed on first in the housing, the second rotating shaft, described housing comprises: base portion, both sides from base portion upwards bend first of extension, the second sidewall reaches and bends first of extension downwards from the two ends of base portion, the second end wall, described the first end wall is provided with several installing holes, described the first side wall is provided with the first inclined hole and the second inclined hole, described the second sidewall is provided with the 3rd inclined hole and the 4th inclined hole, one end of described the first rotating shaft is provided with the first installation portion, the other end of described the first rotating shaft is provided with the second installation portion, described the first installation portion is installed in the first inclined hole and protrudes out the first inclined hole, described the second installation portion is installed in the 3rd inclined hole and protrudes out the 3rd inclined hole, one end of described the second rotating shaft is provided with the 3rd installation portion, the other end of described the second rotating shaft is provided with the 4th installation portion, described the 3rd installation portion is installed in the second inclined hole and protrudes out the second inclined hole, described the 4th installation portion is installed in the 4th inclined hole and protrudes out the 4th inclined hole, the upper end of described the first side wall is bent with the first fold turn of bilge, the upper end of described the second sidewall is bent with the second bending part, between described first fold turn of bilge and the 3rd installation portion the first spring is installed, be provided with the second spring between described the second bending part and the 4th installation portion, be provided with the 3rd spring between described the second end wall and the second installation portion, be provided with the 4th spring between described the second end wall and the first installation portion.
The invention has the beneficial effects as follows: by paper advance mechanism being installed on the paper inlet place of printer, printing paper passes through first this paper advance mechanism before entering printer, when printing paper is transferred to two rotating shafts place, rotating shaft is flat letterweight, pressing through twice, make smooth that paper becomes when entering printer, therefore can effectively prevent the printer paperboard phenomenon that causes because of the paper fold.
