Improved screen print production line of figure-number steel plates

Abstract

The invention provides an improved screen print production line of figure-number steel plates. The improved screen print production line combines the screen print and the roller coating print, and therefore not only can acquire comparatively accurate underpainting patterns but also can acquire comparatively massive and highly three-dimensional printing layers; and meanwhile a servo control system, which is used for controlling the rotational speed and starting time of the material adsorbing roller and the coating roller of a roller equipment component, is added to a roller painting section, so that the consistency of linear velocity of a practical roller face and the rotational speed of the technology is ensured. Thus, the production line does not need to be stopped for an adjustment in the production process and the 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 ...

AI Technical Summary

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 speed of the cover roller is adjusted on-line by the control system, which often needs to stop and adjust after the entire production line has been running for a period of time, which affects the efficiency of the entire production line; and if the adjustment is not stopped, the speed of conveying the steel strip will be different from the The roller surface line speed of each roller is inconsistent, which often leads to the inability to carry out roller coating transfer printing on the steel strip according to the predetermined position; in addition, in order to print multi-color patterns, it often requires several groups of roller coating equipment components to work together, while the prior art The above-mentioned roller coating equipment assembly lacks a kind of control system that makes the continuous production of adjacent roller coating equipment components, that is, it needs the staff to observe whether the first roller coating equipment assembly has finished coating a color by human eyes, and determine whether the coating is completed. After the coating is completed, the adjacent roller coating equipment components are manually started, 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, This makes it impossible to correct errors when the patterns printed by adjacent roller coating equipment components are misaligned
