A printing and paper feeding device

Abstract

The invention discloses a printing paper conveying device. The device comprises a supporting plate, a conveying motor, a paper rubbing motor and a suction fan; and the conveying motor is arranged at the top end of one side of the supporting plate, the paper rubbing motor is arranged on one side of the conveying motor, the suction fan is arranged between the conveying motor and the paper rubbing motor, one end of the conveying motor is connected with a conveying motor transport disc, one end of the paper rubbing motor is connected with a paper rubbing motor transport disc, the conveying motor and the paper rubbing motor are in transmission connection through an arranged gear set, a supporting frame is arranged on one side of the gear set and located on the supporting plate, a conveying gear is arranged at the bottom of one end of the supporting frame, one end of the paper rubbing motor transport disc is connected with a connecting rod, one end of the conveying motor is connected with an air suction pipe, the middle of the connecting rod is connected with a paper rubbing mechanism, and through the arrangement of the conveying motor and the paper rubbing motor, paper is fed into a printer. The conveying motor and the paper rubbing motor are in transmission connection through the arranged gear set, and therefore stable conveying force can be stably provided; and the suction fan is arranged on the supporting plate, and is used for sucking the paper, and the stacked paper can be prevented from entering the printer.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a printing paper feeding device. Background technique [0002] Printing (Graphic Communications, that is, graphic communication) is to transfer the ink to the surface of paper, fabrics, plastics, leather and other materials through plate-making, ink application, and pressure on originals such as text, pictures, photos, and anti-counterfeiting, and to reproduce them in batches. The technology of original manuscript content usually includes flat paper printing (also known as sheet-fed printing, which is printed on flat paper) and web printing (also known as rotary printing, which uses web printing) in printing. These two kinds of printing all need the paper feeding device to supply paper for it, and the existing paper feeding device is easy to jam during printing due to the single function, which seriously affects the printing efficiency.
