Paper separating device having function of suppressing noise, automatic paper feed device and manufacturing method thereof

Abstract

The invention relates to a paper separating device having a function of suppressing noise, an automatic paper feed device and a manufacturing method thereof. The paper separating device is used for the automatic paper feed device, wherein the automatic paper feed device is provided with a paper separating roller arranged in a paper guide path. The paper separating device at least comprises a paper separating pad, a paper separating seat, an elastic element and a noise suppression element, wherein the paper separating pad is arranged in the paper guide path and is opposite to the paper separating roller for matching with the paper separating roller to separate paper passing through the paper guide path; the paper separating seat is provided with a first surface for arranging the paper separating pad; the elastic element is adjacent to the paper separating seat and is used for butting against or connecting the paper separating seat to ensure that the paper separating seat drives the paper separating pad to press the paper separating roller; and the noise suppression element is arranged on the paper separating seat and used for changing natural frequency dynamic response of a combination of the paper separating pad and the paper separating seat to ensure that the natural frequency dynamic response deviates from a working frequency of the paper separating roller and a resonant frequency. Therefore, the paper separating device can avoid resonance so as to achieve the effect of obviously suppressing the noise generated in operation.
