Embodiment Construction

[0012] together with reference figure 1 and figure 2 , the paper taking mechanism 1 comprises a main body frame 11, a transmission gear 12 fixed on the main body frame 11, two paper fetching rollers 13, two transmission shafts 14 and two planetary helical gears 15 fixed in the transmission gear 12, wherein the transmission gear 12 The center line of rotation of the two planetary helical gears is perpendicular to the center line of rotation of the two planetary helical gears 15. One end of each transmission shaft 14 is fixed with a helical gear 142 meshing with the planetary helical gear 15 , and the two paper pickup rollers 13 are fixedly connected to a transmission shaft 14 . In this way, the transmission gear 12 , the two transmission shafts 14 and the two planetary helical gears 15 constitute a differential device for adjusting the rotational speed of the two paper-fetching rollers 13 .

[0013] The main frame 11 includes two fixed frames 110 arranged parallel to each ot...

Abstract

The invention provides a paper taking mechanism comprising a main frame, a transmission gear which is fixed on the main frame, and two paper taking rollers which are fixed on the main frame; the paper taking mechanism is connected with a motor; the paper taking mechanism further comprises a transmission gear which transmits power to the two paper taking rollers from the motor; and the transmission gear is a differential gear which is capable of adjusting the rotation speed of the two paper taking rollers so as to adjust the deflection of the paper. With the adoption of the paper taking mechanism, the problem caused by the paper arranged in a paper box in a slanting mode is solved.

Description

technical field [0001] The invention relates to a paper fetching mechanism, in particular to a paper fetching mechanism capable of adjusting the speed of a paper fetching roller. Background technique [0002] The paper-feeding mechanism is arranged on target devices such as fax machines, scanners, printers, copiers, etc., and is used for conveying the paper placed in the paper tray. When the existing paper pick-up mechanism transports the paper, if the paper is placed crookedly in the paper cassette, when picking up the paper, the pick-up arm will directly send out the crooked paper and affect the printing quality; if the amount of skew is large, it is easy to cause paper jams. Contents of the invention [0003] In view of this, it is necessary to provide a paper picking mechanism that can solve the above-mentioned problems caused by the skewed placement of paper in the paper tray. [0004] The invention provides a paper-fetching mechanism, which includes a main body fra...
