Paper supply device capable of automatically replacing roll paper

Abstract

The invention discloses a paper supply device capable of automatically replacing roll paper. The paper supply device comprises a device body, wherein the device body consists of a paper supply box, arotating cylinder and a fixing block, wherein the paper supply box is arranged on the side surface of the device body; the rotating cylinder is arranged on the side surface of the paper supply box; the fixing block is arranged on the side surface of the rotating cylinder. According to the paper supply device capable of automatically replacing roll paper, a speed adjuster is controlled by rotatingan adjusting knob, the rotation speed of a Y2-90L-4 electromotor is further controlled by the speed adjuster, then the rotation speed of a roller is controlled, the paper supply speed is further adjusted, an optimal paper supply effect is adjusted conveniently, and very good practicability is achieved; meanwhile, rolls of which paper is used up are sucked through electromagnets, new rolls are pushed to the middle of the rotating cylinder through hydraulic rods, then paper can be supplied again, the paper supply efficiency is greatly improved, a great amount of labor resources are saved, and the workload of operators is alleviated; in addition, paper is pressed by a paper guide, then the paper can be moved in a correct direction, the paper is prevented from damage, and the paper utilizationrate is increased.

Description

technical field [0001] The invention relates to the technical field of paper feeding devices, in particular to a paper feeding device that can automatically replace roll paper. Background technique [0002] Generally, an image forming apparatus such as a stencil printer includes a paper feeding device for feeding printing paper to an image forming unit. Due to the locking mechanism of the guide guard, one or more guide guards are moved along the paper width direction according to the size of the printing paper. This kind of paper feeding device cannot automatically replace the roll paper. With the development of science and technology, given There are more and more paper devices, and their functions are becoming more and more powerful. Among them, there are more paper feeding devices that can automatically replace the roll paper. [0003] However, most of the existing paper feeding devices cannot adjust the paper feeding speed, resulting in poor applicability. At the same t...

Problems solved by technology

[0003] However, most of the existing paper feeding devices cannot adjust the paper feeding speed, resulting in poor applicability. At the same time, the roll paper cannot be replaced automatically, which consumes manpower and is very inconvenient. Moreover, it cannot press the paper, so that the paper cannot move in the correct direction.
