Problems solved by technology

[0002] Office equipment such as printers or copiers are usually equipped with a paper conveying device for conveying paper. The paper conveying device usually includes a paper guide roller and a paper feed wheel. The paper wheel rotates to transport the paper, but when the tail of the paper breaks away from the paper guide roller and the feed roller, the tail of the paper will suddenly arch, especially when printing hard paper, the arch will be large, which will cause the paper and inkjet A sudden change in the distance between the heads, resulting in a sudden change in the color of the pattern printed on the paper

Embodiment Construction

[0012] see figure 1 , In a preferred embodiment of the present invention, a paper conveying device can be applied in a printer or a copier, and the paper conveying device includes a base 10, a paper feed wheel 20, a paper guide roller 30, a cam 40 and A pallet of 50.

[0013] The paper feeding wheel 20 and the paper guide roller 30 are arranged opposite but not in contact, and a paper conveying channel 21 is arranged between the two, and the paper conveying channel 21 is provided with a paper output direction, and the paper output direction is usually in line with the guide roller. The line connecting the central axis of the paper roller 30 and the central axis of the paper feed wheel 20 is vertical, and a paper 90 is positioned in the paper conveying path 21, and the paper feed wheel 20 and the paper guide roller 30 all rotate to make the paper 90 follow the output of the paper 90. The paper orientation is passed out.

[0014] The base 10 includes a connecting plate 11 and ...

Abstract

The invention discloses a paper conveying device. The paper conveying device comprises a paper guiding roller, a paper feeding wheel and a base body. The paper guiding roller is mounted on the base body. The paper guiding roller and the paper feeding wheel are oppositely arranged, and a paper conveying channel is formed between the paper guiding roller and the paper feeding wheel. The paper conveying channel has a paper discharging direction. A cam is adjacent to the base body. The cam rotates so as to push the base body. The base drives the paper guiding roller to move synchronously, so that the paper discharging direction of the paper conveying channel is changed.

Description

technical field [0001] The invention relates to a paper conveying device, in particular to a paper conveying device capable of adjusting the paper output angle. Background technique [0002] Office equipment such as printers or copiers are usually equipped with a paper conveying device for conveying paper. The paper conveying device usually includes a paper guide roller and a paper feed wheel. The paper wheel rotates to transport the paper, but when the tail of the paper breaks away from the paper guide roller and the feed roller, the tail of the paper will suddenly arch, especially when printing hard paper, the arch will be large, which will cause the paper and inkjet The distance between the heads changes suddenly, which causes sudden changes in the color of the pattern printed on the paper. Contents of the invention [0003] In view of the above, it is necessary to provide a paper conveying device that prevents the paper from suddenly arching. [0004] A paper conveyi...
