Flat screen printing and digital printing combined printing device and method

Abstract

The invention provides a flat screen printing and digital printing combined printing device and method. The flat screen printing and digital printing combined printing device and method are good in printing precision and convenient to install and adjust. A spray head frame of a digital printing device is arranged above a conveying belt through a portal frame structure, and the portal frame structure stretches across the conveying belt. The portal frame structure comprises a stand column, a printing beam, a guide rail, beam up-down adjustment mechanisms and beam front-back adjustment mechanisms. The printing beam is installed on the stand column through the beam up-down adjustment mechanisms and the beam front-back adjustment mechanisms and horizontally arranged above the conveying belt. The spray head frame is installed on the printing beam in a sliding mode through the guide rail and can move left and right along the printing beam. The beam up-down adjustment mechanisms are connected with the left end and the right end of the printing beam and used for adjusting the up-down positions of the left end and the right end of the printing beam. The beam front-back adjustment mechanisms are connected with the left end and the right end of the printing beam and used for adjusting the front-back positions of the left end and the right end of the printing beam. Accordingly, flat screen printing mark symbols and digital printing mark symbols are completely overlapped.

Description

technical field [0001] The invention relates to a printing device and a printing method thereof, in particular to a printing device and a printing method combining flat screen printing and digital printing. 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 of...

Problems solved by technology

However, in this technical solution, the digital printing machine is set on the frame of the flat screen printing machine. Once installed, the position cannot be changed. For example, if it is installed before the flat screen, it can only be digitally printed first. The flat screen printing is performed first, and the adaptability is relatively small, and since the digital printing machine is set on the frame of the flat screen printing machine, it cannot be conveniently moved to other positions for other printing operations at ordinary times, and its expensive equipment investment is a waste, and how to realize the precise overprinting method of screen printing and digital printing in this patent application is not disclosed
