Abstract
The utility model discloses a printer paper feeding correcting device, which comprises an upper roller shaft, a lower roller shaft, a transport roller wheel arranged on the upper roller shaft and the lower roller shaft and a paper stopping board, wherein, the outer diameter of one transport roller wheel is longer than the outer diameters of the other transport roller wheels. The outer diameters of the other transport roller wheels are equal. The utility model just conducts reconstruction simply on the structure of the original printer paper feeding. The outer diameter of one transport roller wheel is enlarged. The utility model has simple structure, convenient use and good correcting effect.
Description
[technical field]
The utility model relates to a kind of printer paper feed deviation correcting device.
[background technology]
Conventional printer paper feed deviation correcting device comprises roll shaft, lower roller shaft, is installed in paper-feeding roller, pressing board on the upper and lower roll shaft, and wherein the external diameter of all paper feed running rollers equates.It relies on pressing board that the barrier effect of paper feed is rectified a deviation.When paper is when tiltedly putting, behind the paper feed, have an end and run into pressing board earlier, all the paper feed running rollers on this moment roll shaft all are rotated further, and by pressing board paper are corrected.When paper heads on pressing board, all paper feed running rollers are still with the same stressed the rotation, all paper feed running rollers are all with pressure friction paper feed of a size like this, even when paper has an end to be withstood by pressing board, under all paper feed running roller same function power, paper is subjected to identical frictional force effect, and paper will be with same direction paper feed, will certainly cause paper to be squeezed wrinkle, thereby not reach good rectifying effect.
[summary of the invention]
The problem that the utility model need solve just is to provide a kind of printer paper feed deviation correcting device, and it has overcome the not good defective of rectifying effect in the prior art, can reach comparatively desirable rectifying effect.
For addressing the above problem, the utility model adopts following technical scheme:
The utility model printer paper feed deviation correcting device comprises roll shaft, lower roller shaft, is installed in paper-feeding roller, pressing board on the upper and lower roll shaft, and the external diameter of one of them paper feed running roller is greater than the external diameter of other paper feed running roller, and the external diameter of other paper feed running roller equates.
Preferably, big external diameter paper feed running roller described in the utility model is installed on the roll shaft middle position with respect to print media.
The utility model only allows this paper feed running roller contact paper rotate in the correction process by strengthening the external diameter of a paper feed running roller, and the unsettled or stressed minimizing of other paper feed running rollers, thereby reaches the purpose of correction.Because in the correction process of reality, have only a paper feed running roller rotating, be equivalent to so just avoid the phenomenon of crowded paper to central point that rotates around this paper feed running roller of paper feed medium.When paper is when tiltedly putting, behind the paper feed, have an end and run into pressing board earlier, have only a paper feed running roller friction paper feed this moment on the roll shaft, when paper had an end to be withstood by pressing board, paper was subjected to the effect of this running roller frictional force, rotate around this paper feed running roller, thereby reach good rectifying effect.
Advantage of the present utility model is that it just transforms simply on original printer paper feed structure, strengthen the external diameter of a paper feed running roller, and simple in structure, easy to use, rectifying effect is good, is particularly useful for bankbook and prints.
[description of drawings]
Fig. 1 is the utility model structural representation.
[specific embodiment]
As shown in Figure 1, the utility model printer paper feed deviation correcting device, comprise roll shaft 1, lower roller shaft 2, be installed in paper-feeding roller 3 on the upper and lower roll shaft, be installed in the pressing board in the paper feed channel of paper feed running roller back, the shelves scraps of paper that can raise and reduce are arranged behind the following paper feed Kun wheel, the external diameter of one of them paper feed running roller 3a is greater than the external diameter of other paper feed running roller, and the external diameter of other paper feed running roller equates.Print media 4 enters printer in the paper feed channel in the middle of the upper and lower paper feed running roller, big external diameter paper feed running roller 3a is installed on the roll shaft middle position with respect to print media.
Claims (3)
1, a kind of printer paper feed deviation correcting device, comprise roll shaft (1), lower roller shaft (2), be installed in paper-feeding roller (3), pressing board on the upper and lower roll shaft, it is characterized in that: the external diameter of one of them paper feed running roller (3a) is greater than the external diameter of other paper feed running roller, and the external diameter of other paper feed running roller equates.
2, the described deviation correcting device of claim 1 is characterized in that: described big external diameter paper feed running roller is installed on the roll shaft.
