Paper feeding device for vertical printing machine

Abstract

The invention relates to the technical field of intelligent manufacturing, and discloses a paper feeding device for a vertical printing machine. The paper feeding device comprises a machine frame, a limiting groove is formed in one side of the front surface of the machine frame, the inner part of the limiting groove is movably connected with a clamping plate, one side of the top end of the machineframe is in threaded connection with a driving motor, and a transmission gear is arranged on the outer surface of a transmission screw rod. The paper feeding device for the vertical printing machinedrives a paper wrinkling roller and a friction belt to rotate synchronously and reversely through the arrangement of the transmission gear, the paper wrinkling roller, a driven gear and the friction belt; when the paper feeding device works, the upper side and the lower side of printing paper can generate a speed difference, so that printing paper overlapped together can be effectively separated,the printing paper which is adhered and adsorbed together is separated and adhered by adopting a speed difference mode compared with the prior art, the efficiency of the paper feeding device is high,the stability is good, the generated paper wrinkling force is large, the phenomenon that the paper cannot be separated due to too large friction force between the printing paper, or the paper is not fed and the paper wrinkling roller rotates idly due to too small friction force is avoided.

Description

technical field [0001] The invention relates to the technical field of intelligent manufacturing, in particular to a paper feeding device for a vertical printing machine. Background technique [0002] The paper feeding device of the printer is a device that feeds unprinted paper into the printer for printing, and since the printer prints one by one, the paper feeding device must ensure that the printed paper fed into the printer is There is only one piece of paper. [0003] Therefore, in order to ensure that there is one and only one piece of paper entering the printer, the currently used paper feeding devices use the different friction forces between the pickup roller, printing paper and friction plates to separate and feed the paper, so that Avoid the problem that two or more sheets of printing paper enter the printer at the same time, but because the friction between the printing papers is not constant, when the environment is relatively humid, the printing paper will be...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a paper feeding device for a vertical printing machine, which has the advantages of effectively separating printing paper, preventing the printer from feeding multiple sheets at a time, and preventing the printer from feeding paper due to too small frictional force. It solves the problem that when the environment is relatively humid, the printing paper will be damp and sticky, which will cause the printer to feed two or more sheets at a time, and eventually cause the printer to fail to eat normally and shut down. When the environment is relatively dry, the printing paper will Static electricity will be generated between them and they will be attracted to each other. It is difficult to separate them using the existing pickup rollers and friction sheets. There will also be a problem that the printer feeds multiple sheets at a time, and the dry paper will reduce its contact with the pickup roller. The friction between the roller and the friction plate, which causes the problem that the pickup roller is idling and does not feed the paper
