[0002] A printer is a common printing device that can print different patterns and texts on the surface of paper. When an existing printer is in use, it usually relies on a paper feeding mechanism to transport the paper to be printed to the bottom of the printing device, and then the printing device can print text patterns on the surface of the paper.

[0003] In order to ensure that the paper remains flat during printing, the existing printer paper feeding mechanism usually uses a supporting plate to support the paper. Although the supporting effect is good, due to the large contact area with the paper, the friction between the paper and the supporting plate is also large when feeding the paper, which may generate dust and may affect subsequent operations. The dust prevention effect is poor. Therefore, a paper feeding mechanism with a dust prevention effect is proposed to solve the above problem. Utility Model Content

When it is adjusted to a suitable position, the lever 46 can be released, and the fixing spring 44 will push the side plate 43 to drive the fixed block 42 to move backward and re-enter the fixed slot 45. At this time, the fixed plate 41 will be fixed and cannot move up and down.

[0033] When it is necessary to adjust the distance between the two sets of paper feed shafts 6, the pull rod 58 can be pushed backward to drive the adjustment block 51 to move backward, and the adjustment block 51 will drive the adjustment rod 53 to move backward synchronously. The adjustment rod 53 moves backward and enters the vertical groove 55 from the inside of the horizontal groove 56. At this time, the arc groove plate 54 will be able to move up and down. By moving the arc groove plate 54 up and down, the arc groove 57 can be used to squeeze the rotating shaft 7 to drive the two sets of paper feed shafts 6 to move closer or farther away. When the distance between the two sets of paper feed shafts 6 is adjusted, the pull rod 58 can be released, and the adjustment spring 52 will push the adjustment block 51 outward to drive the adjustment rod 53 to re-enter the inside of the horizontal groove 56.
