20160052254 | METHOD FOR PRODUCING A PATTERNED STEEL PLATE BY USING ROLLER-COATING PRINTING AND SCREEN PRINTING - A method for producing a patterned steel plate by using roller-coating printing and screen printing, and a ground color pattern produced can be more accurate and a thicker and solider printing layer with a stronger stereo perception can also be obtained by using the roller-coating printing and screen printing, meanwhile in roller coating section, a servo control system is further included to control the rotate speed of each roller of the roller coating equipment and the preset time, thus ensuring that the actual roller surface linear velocity is consistent with the process rotation speed, so there is no need to stop the line for adjusting in the production process, thus increasing the production efficiency. | 02-25-2016 |
20150343479 | CONTROL METHOD AND CONTROL SYSTEM USED FOR ROLLER COATING PRINTING PRODUCTION LINE - The present invention provides a control method used in a roller coating production line, wherein by calculating and controlling the theoretical roll surface linear velocity and actual roll surface linear velocity of each roller in a roller coating unit, the rotational speed of each roller is kept consistent with the process speed, increasing production efficiency. At the same time, calculating a pattern misplacement distance in repeat printing by means of code recognition technology, thereby adjusting the rotational speed of each roller, achieves lifelike and holonomic patterning in multicolored printing and extends the printed length of the pattern. | 12-03-2015 |
