Non-contact type gas-liquid comprehensive cleaning device applied to digital printing machine

Abstract

The invention discloses a non-contact type gas-liquid comprehensive cleaning device applied to a digital printing machine, The non-contact type gas-liquid comprehensive cleaning comprises a base, a water storage cavity, a cleaning pump, a mounting seat, a mounting groove and a water outlet, wherein the water storage cavity is formed in the base and used for temporarily storing cleaning liquid, thecleaning pump communicates with the water storage cavity and used for pumping the cleaning liquid into the cleaning pump, the mounting seat is arranged on the surface of the base and used for abutting against the bottom surface of a printing spray head, the mounting groove is formed in the surface of the mounting seat and used for mounting a printing area on the printing spray head, and the wateroutlet is formed in the bottom surface of the mounting groove, communicates with the water storage cavity and is used for spraying the cleaning liquid on the printing area on the printing spray head.Therefore, the printing area on the printing spray head can be effectively prevented from being damaged in the cleaning operation due to the fact that a water outlet of a core cleaning part is not indirect physical contact with the printing area on the printing spray head, and meanwhile the cleaning liquid is automatically sprayed through the power of the cleaning pump, so that the cleaning operation on the printing spray head of the digital printing machine can be conveniently and efficiently completed.

Description

technical field [0001] The invention relates to the technical field of printing machines, in particular to a non-contact gas-liquid comprehensive cleaning device applied to digital printing machines. Background technique [0002] With the development of printing technology in China, more and more printing equipment has been widely used. [0003] A printing press is a machine used to print text and images. A modern printing press generally consists of mechanisms such as plate loading, ink application, embossing, and paper feeding (including folding). At present, digital printing machines have become the mainstream printing machines on the market. There are many types of digital printing machines. Among them, the single pass digital printing machine is specially used in the digital printing industry. It is generally composed of 4 groups of nozzles arranged in 4 rows. C, M, Y, K primary colors. [0004] The running time of the digital printing machine is generally long. In o...

Problems solved by technology

[0005] However, when using the first method in the prior art for cleaning operations, if the scraper used is not parallel to the nozzle, the belt is too loose or too tight, etc., it will cause cleaning problems, and it will take a long time to install and debug the belt and scraper. At the same time, the squeegee also needs to be replaced regularly to prevent the squeegee from being damaged for a long time and affect the cleaning effect, and the direct contact with the nozzle is easy to damage the printing area on the print head, and finally the cleaning effect of the squeegee is difficult to achieve a satisfactory cleaning effect, and the Single The number of nozzles in pass printing equipment is large and expensive, and direct contact cleaning is likely to increase the damage rate of nozzles

When using the second manual maintenance method in the prior art for cleaning operations, due to the large number of printing nozzles and the tight arrangement, the manual operation takes longer, and the operating space on the digital printing machine is limited, maintenance and cleaning operations It is cumbersome and difficult to operate
