Problems solved by technology

However, in order to increase the paper-feeding speed, an office machine equipped with an automatic paper-feeding device will increase the speed at which the paper-feeding arm rotates from the standby position to the paper-feeding position, and at this time the strength of the paper-feeding arm hitting the paper inlet will also increase accordingly. , thus causing greater vibration and noise
If this situation is not improved, it may even reduce the life of the pickup arm

Embodiment Construction

[0035] According to a specific embodiment of the present invention, an automatic paper feeding device is provided, which can be applied to a multifunctional business machine or an automatic paper feeding scanner.

[0036] image 3 It is an exploded view showing an automatic paper feeding device according to a preferred embodiment of the present invention. The automatic paper feeding device 2 includes a paper picking module 20 and a floating shock-absorbing structure 21 . The paper-feeding module 20 is used to feed paper into the interior of the automatic paper feeding device 2, including a paper-feeding arm 201 and a rotating shaft 202, while the floating shock-absorbing structure 21 includes a groove 211 at the paper inlet 22, a foam 212 And a friction plate 213.

[0037] Continue to refer to image 3 , the foam 212 is set in the groove 211 (please also refer to Figure 4A ), and the foam 212 does not fill the groove 211, and the friction plate 213 covers the groove 211 (...

Abstract

The invention provides an automatic paper feeding device. The device comprises a paper taking module and a floating vibration absorption structure arranged on a paper inlet. The paper taking module is provided with a paper taking roller, and a paper separation roller. When the paper taking module is rotated to the paper taking position, the paper taking roller is contacted with the floating vibration absorption structure to ensure that paper is fed into the automatic paper feeding device. By arranging the floating vibration absorption structure, the impact force on the paper inlet and noise produced when the paper taking roller takes paper are reduced.

Description

technical field [0001] The invention relates to an automatic paper feeding device, in particular to an automatic paper feeding device which reduces vibration and noise generated when a paper picking arm picks up paper. Background technique [0002] Multifunctional business machines and scanners are common office tools nowadays. In order to increase the scanning speed by continuously feeding multiple sheets, there are multifunctional business machines and scanners equipped with automatic paper feeding devices. However, with the increase of scanning speed, the speed of paper picking is also accelerated, and greater vibration and noise will be generated during the paper picking process, which may even affect the service life of the machine. [0003] figure 1 It is an existing automatic paper feeding device disclosed by US Patent No. US6792241. figure 1 The automatic paper feeding device 1 includes a paper picking arm 10 , a paper picking roller 11 , a paper separating pad 12 ...
