TECHNICAL FIELD

[0001] The present application relates to the technical field of five-color printing machines, in particular to a feeding and conveying device of a five-color printing machine. BACKGROUND

[0002] A five-color printing machine is a device for spraying color ink on the surface of paper to transmit literal information, and its basic colors are black, blue, red and yellow. Four-color printing in the printing industry is formed by superimposing these four primary colors. Five-color printing actually adds a special color, i.e., spot color, to the four primary colors. Five-color printing has a very obvious improvement in printing effect, with full and realistic effects. The feeding device of a five-color printing machine usually includes a feeding table that can be lifted on a rack and a tray on the feeding table, which carries the paper to be printed.

[0003] The existing feeding and conveying device raises the feeding table when feeding, and the feeding table drives the tray and the paper to be printed on the tray to move upwards until the feeding position. When the paper to be printed on the tray is completely fed, the printing is stopped, the feeding table drives the tray to descend, and a stack of paper to be printed is transported to the tray, arranged neatly, and then the printing starts. This process is time-consuming and inefficient, so the feeding and conveying device of a five-color printing machine needs to be improved. CONTENT OF THE INVENTION
