Printing device combined with screen printing and digital printing and printing method thereof

Abstract

The invention relates to a screen printing and digital printing combined printing device and a printing method of the screen printing and digital printing combined printing device. At present, no printing method or printing method which is high in printing precision and printing speed exist. The printing device is characterized by comprising a machine frame, a rotating roller, a conveyer belt, a screen printing mechanism and a digital printing mechanism, the conveyer belt is installed on the rotating roller, the screen printing mechanism is installed on the machine frame, the digital printing mechanism is installed on the machine frame, and the screen printing mechanism is matched with the digital printing mechanism. The printing method is characterized in that shell fabric is driven to move through the conveyer belt, the shell fabric is printed through the screen printing mechanism and the digital printing mechanism, and if patterns needing to be printed on the shell fabric include large pieces of patterns, the patterns are printed through the screen printing mechanism; if the patterns needing to be printed on the shell fabric include high-precision patterns, the patterns are printed through the digital printing mechanism. The printing device and the printing method are reasonable in structural design, reliable in performance, high in printing precision and high in printing speed.

Description

technical field [0001] The invention relates to a printing device and a printing method thereof, in particular to a printing device combining screen printing and digital printing and a printing method thereof. Background technique [0002] Currently commonly used printing methods are divided into screen printing methods and digital printing methods. Among them, the screen printing method has the advantage of fast printing speed, but the printing accuracy is not high, and it is difficult to print fine patterns with high precision requirements; while digital printing Although the method has the function of being able to print fine patterns, the printing speed is slow, and it is difficult to print patterns of large color blocks, because it is difficult for the nozzles in the digital printing process to eject patterns of large color blocks conveniently and effectively. Under normal circumstances, the precision required for the pattern of large color blocks is low, and the method...

AI Technical Summary

Problems solved by technology

The printing accuracy can be improved to a certain extent through the independent servo motor control and vertical lifting device. However, the full servo control flat screen printing machine still belongs to screen printing, and the printing accuracy cannot reach the level of digital printing.

Another example is that the publication date is April 25, 2012, and the Chinese patent with the publication number CN102423959A discloses a horizontal wallpaper rotary screen printing machine, which includes a belt-type horizontal conveyor , a sizing device is installed in the middle, and at least two sets of rotary screen printing units are installed above it. Each set of rotary screen printing units includes a squeegee assembly, a rotary screen printing head assembly and a lifting mechanism. On the belt horizontal conveyor Located between every two sets of rotary screen printing units, equipped with a set of drying units; the rotary screen printing head assembly in the rotary screen printing unit includes left and right screen head seats, on the center line of the right screen head seat There is a horizontal chute, which is equipped with a guide shaft, and the guide shaft is fixed on the lifting seat of the lifting mechanism; on the left net head seat, there are horizontal chute and longitudinal chute respectively on both sides of the center line. The chute is respectively equipped with eccentric swing mechanism, and the two eccentric swing mechanisms are fixed in the lifting seat of the lifting mechanism. This horizontal wallpaper rotary screen printing machine solves the problem of low precision of gravure printing and flat screen printing speed However, the horizontal wallpaper rotary screen printing machine still belongs to screen printing, and the printing accuracy cannot reach the level of digital printing, and its structure is complicated, so it is mainly used in the printing process of wallpaper

[0004] In summary, there is no such thing as a printing device and printing method with reasonable structural design, reliable performance, high printing precision, and fast printing speed.
