Screen printing production line of image coding steel plate

Abstract

The invention provides a screen printing production line of an image coding steel plate. The screen printing production line of the image coding steel plate combines screen printing and roller painting, and not only can obtain accurate underpainting patterns, but also can obtain a thick and strong three-dimension printing layer. Meanwhile, a servo control system which controls rotate speed and starting time of a suction roller and a coating roller of a roller coating equipment element is added at a roller painting section to ensure that actual roller surface line speed is consistent with process rotate speed, accordingly line stopping adjustment is not needed in the process of production, and production efficiency is improved.

Description

technical field [0001] The invention relates to a silk-screen printing production line for pattern-coded steel plates, belonging to the field of pattern-coded steel plate production and manufacturing. Background technique [0002] 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. [0003] The basic process of printing with screen printing equipment components is: when printing, pour ink on one side of the screen printing plate, apply a certain pressure on th...

Problems solved by technology

[0007] 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
