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...
