Intelligent ink supply control system for metal sheet printing and method thereof

Abstract

The invention discloses an intelligent ink supply control system for metal sheet printing and a method thereof. The intelligent ink supply control system comprises a service expansion interface, an integrated controller, a control function module and a foundation database which are connected in sequence, wherein the service expansion interface has the function of completing communication with data of an external user and data of a local user and comprises a generic technology interface, a remote monitoring interface and a user interface; the integrated controller has the functions of completing driving control over 32 ink keys, driving control over a motor through a single chip microcomputer and real-time control over ink key opening degree; the control function module completes intelligent preset of the ink quantity, detection and monitoring of the thickness of an ink layer, fault diagnosis, maintenance and remote diagnosis which are achieved through an industrial PC; the foundation database has the functions of completing storing, invoking and editing of process parameters and printing standard patterns, and the functions are achieved by using a data server through a database programming language. According to the intelligent ink supply control system for metal sheet printing and the method thereof, the intelligent ink supply control system which is high in quality, low in consumption and fully automatic and intelligent in operation is provided for metal sheet printing equipment.

Description

technical field [0001] The invention belongs to the technical field of metal sheet printing and coating equipment, in particular to an intelligent ink supply control system for metal sheet printing and coating and a method thereof. Background technique [0002] Before metal sheet printing, it is necessary to determine the ink supply volume of the corresponding area according to the pattern distribution and color tone of the printed product, and adjust the gap between the ink knife and the ink roller (also called the opening of the ink key), which is called ink volume preset. At present, the ink volume preset adjustment of various domestic printing machines generally adopts manual methods. When starting up, the operator manually observes the proofs and combines operating experience to pre-set the ink key opening, then starts up for trial printing, and then decides to make further repeated adjustments according to the printing results. This adjustment method not only requires...

AI Technical Summary

Problems solved by technology

This adjustment method not only requires workers to have rich operating experience, but also the entire adjustment process needs to be repeated many times, the operation process is complicated, the efficiency is low, and it will also cause waste of resources such as printing time, equipment, printing ink and metal plates.

Even if the ink supply is carefully adjusted at the beginning of printing, the actual ink supply will change due to various factors during the actual printing process, which will affect the printing quality

At present, the quality tracking of this process is basically judged manually based on experience and feeling, and it is difficult to meet the continuous development of high-quality, high-speed printing needs.
