Paper feeding assembly used for printer

Abstract

The invention discloses a paper feeding assembly used for a printer, comprising support feet, a working table and an electrostatic generator, wherein the working table is arranged on the upper side ofthe support feet; the electrostatic generator is arranged on one side of the working table away from the support feet. According to the invention, the beneficial effects of the paper feeding assemblyare: by arranging the electrostatic generator, conductive brush heads and a discharging brush, a paper and a conveyor belt are tightly coupled, so that the separation phenomenon of the paper can be avoided; by arranging a displacement sensor, an electric stretching shaft and a side baffle, the deviation of the paper can be timely corrected, so that the normal transportation and printing of the paper can be ensured; and by arranging an ultrasonic thickness detector, the overlapping phenomenon of the paper can be avoided, so that the waste caused by wrong paper printing is reduced.

Description

technical field [0001] The invention relates to the field of printing machines, in particular to a paper feeding device for printing machines. Background technique [0002] When the printing machine is working, it needs to transport the printed matter to the printing equipment end, and then print. The device that transports the printed matter is called a paper feeder. The existing paper feeder has certain deficiencies in the paper conveyance during the paper feed process, making the paper feed process unable to be accurately controlled. In the process of paper feeding, the existing paper feeding device relies on the suction cup to absorb the paper to ensure the closeness between the paper and the conveying device, but the suction cup cannot absorb all the paper, so that the paper may be separated from the conveying device. , At the same time, the paper will deviate during transportation. There is no corresponding correcting device for the deviated paper, which causes proble...

The device that transports the printed matter is called a paper feeding device. The existing paper feeding device has certain deficiencies in paper feeding during the paper feeding process, which makes the paper feeding process unable to be accurately controlled.

In the process of paper feeding, the existing paper feeding device relies on the suction cup to absorb the paper to ensure the closeness between the paper and the conveying device, but the suction cup cannot absorb all the paper, so that the paper may be separated from the conveying device. , At the same time, the paper will deviate during transportation. There is no corresponding correcting device for the deviated paper, which causes problems in paper printing. Moreover, the phenomenon of overlapping paper will occur when the paper is transported. The existing device lacks a corresponding The detection device causes waste of paper during printing, so a new type of device is needed to solve the existing problems
