Production method of graph code steel plate integrating roller painting printing and silk-screen printing into whole

Abstract

The invention provides a production method of a graph code steel plate integrating roller painting printing and silk-screen printing into a whole. The silk-screen printing and the roller painting printing are combined. Not only can an accurate grounding decorative pattern be obtained, but also a printing layer which is thick, solid and strong in third dimension can be obtained. Simultaneously, a servo control system which controls the rotating speed of rollers in a roller painting equipment assembly and controls the starting time is additionally arranged in a roller painting segment, and thereby the actual roller surface linear speed is guaranteed to be consistent with the technology rotating speed. Then line-stop adjustment is not needed in the production process, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a production method of a picture-coded steel plate integrating roller coating printing and screen printing. [0002] It belongs to the field of picture code steel plate production and manufacturing. Background technique [0003] Screen printing, together with offset printing, embossing printing, and gravure printing, is called the four major printing methods. Screen printing needs screen printing components to complete. Screen printing equipment components are mainly composed of five major elements: screen printing plate, scraper, ink, printing table and substrate. Among them, the screen printing plate is provided with graphic and text Partial mesh and non-graphic part mesh, the mesh of the graphic part can pass through the ink, and the mesh of the non-graphic part cannot pass through the ink. [0004] The basic process of printing with screen printing equipment components is: when printing, pour ink on one side of the screen...

AI Technical Summary

Problems solved by technology

[0008] However, the applicant found in the process of using the above-mentioned roller coating equipment assembly that the surface speed of the coating roller and the suction roller is often inconsistent with the process speed of the entire production line, and the entire production line lacks the control of the suction roller and coating roller. The control system for online adjustment of the speed of the cover rollers leads to the frequent need to stop the line for adjustment after the entire production line has been running for a period of time, thereby affecting the efficiency of the entire production line; The surface speed of the roller is inconsistent, which often leads to the inability to transfer the roller coating to the steel plate according to the predetermined position; in addition, in order to print multi-color patterns, it often requires several sets of roller coating equipment components to work together, while the above-mentioned in the prior art Roller coating equipment components lack a control system that enables continuous production of adjacent roller coating equipment components, that is, workers need to observe whether the first roller coating equipment component has finished coating a color by human eyes, and determine that the coating is complete After that, the adjacent roller coating equipment components are started manually, so that continuous production cannot be realized between adjacent roller coating equipment components; at the same time, due to the lack of a control system for adjusting the speed of the suction roller and the coating roller, it is impossible to Error correction when patterns printed on adjacent roll coater components are misaligned
