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

Embodiment 1

[0044] Such as figure 1 As shown, this embodiment provides a method for producing a two-color pattern color steel plate, which includes the following steps:

[0045] A. Prepare the steel strip to be printed. In this step, the uncoiler is used to uncoil the steel coil and carry out edge trimming, and the uncoiled steel strip is stitched by a sewing machine;

[0046] B. Using the first roller coating unit to carry out a roller coating transfer to the steel strip to be printed;

[0047] C. After a certain period of time, the second roller coating unit is used to carry out the second roller coating transfer on the steel strip, and the second roller coating transfer and the first roller coating transfer form the specific surface of the steel strip to be printed. background pattern;

[0048] D. placing the steel strip forming the background pattern on the printing table for screen printing, so as to form a pattern code of a specific shape on the steel strip with a specific backgro...

Embodiment 2

[0064] This embodiment provides a method for producing a patterned steel plate that integrates roller coating printing and screen printing. This production method is a deformation based on the production method provided in Example 1, and it is the only difference from Example 1. The difference is that the methods of leveling the steel strips are different. In this embodiment, the specific method of leveling the steel strip is as follows: a plurality of through holes are provided on the printing platform corresponding to the placement position of the steel strip, and a plurality of through holes are provided at the bottom of the printing platform. There is a fan, and when leveling, the fan sucks air through the through hole, thereby forming a negative pressure in the gap space formed between the steel belt and the printing table, and then pressing the steel belt to the The printing table realizes the leveling of the steel strip.

Embodiment 3

[0066] In this embodiment, a structure of the roller coating transfer unit used in steps B and C in Embodiment 1 and Embodiment 2 is provided. For the specific structure, see figure 2 , the roller coating unit includes feeding equipment 1 for providing coating; suction roller 2, whose peripheral surface is connected with the feeding equipment 1, and has an image area formed when filling with the coating on the peripheral surface a plurality of depressions; the rubber coating roller 3, whose peripheral surface is connected with the suction roller 2, is used to accept the image area formed by the coating on the coating roller 3, and transfer the image area onto the steel plate; also includes a first scraper 4, installed on the first scraper bracket, contacting the suction roller 2 at a specific angle, for scraping off the paint outside the image area of ​​the suction roller 2 The second scraper 5, installed on the second scraper bracket, is in contact with the coating rolle...

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...
