An automatic lifting paper pick-up device

Abstract

The invention relates to an automatically lifted paper fetching device, comprising an upper cover, on which a paper fetching mechanism is arranged; the paper fetching mechanism includes a mounting frame, and a gear shaft, a paper separating shaft and a paper fetching shaft are arranged on the mounting frame; the paper fetching shaft The upper coaxial sleeve is provided with a one-way bearing, and the one-way bearing is coaxially fixedly connected with a circular gear; the sliding connection of the mounting frame is provided with a slider; There is a cushioning part for buffering when the slider slides under the pressing force of the upper cover; when the paper is empty, the gear shaft reverses, and the paper taking shaft and the one-way bearing are locked tightly, because the boss is stuck on the tooth of the circular gear at this time. In the mouth, the circular gear, the one-way bearing and the paper take-up shaft do not rotate, so that the paper take-up frame rotates around the gear shaft or the paper separation shaft to lift up. The slider first contacts with the upper cover and drives the upper cover to lift up, completing the empty The purpose of lifting the upper cover of the paper is to use the buffer to buffer, thereby reducing the knocking sound, and at the same time making the lifting action more stable.

Description

technical field [0001] The invention relates to the technical field of paper-fetching modules, and more specifically, relates to an automatically lifted paper-fetching device. Background technique [0002] In printers, scanners and other equipment, the paper-fetching module is one of the most important components; at present, the structure of using the paper-feeding module to pick up paper and lifting the upper cover of the printer or scanner when the paper is not enough, mostly involves Extremely complex or poor stability, and there will be obvious impact when the head is raised.
