1. The parallelism of scraping plate and workbench, depending on the specific screen printing device structure, through adjusting screw around or on either side of the intermediate shaft wire to realize adjustment of scraping plate height position on both ends.The scraper slowly down, to that of the printing machine to contact, look left and then to adjust the interval.Or in the gap on either side of the scraper in thin paper, to keep its relative workbench level.Otherwise, if the clearance around different causes the ink film thickness and uneven spots such as fault.
2. The Angle of scraping board, generally in the range of 65 ~ 85 degrees, according to the specific needs which can adjust the Angle of.
3. The scraping scraping plate speed regulation is usually accomplished by the regulating handle of CVT device, due to the printing device coordination of different parts, so as to ensure the size up speed, large calendar work cycle time is long, the production efficiency is low, and small calendar working cycle time, high production efficiency.
4, scraping board placement location of the debugging
Scraping plate lifting mechanism operating the repeatability of increase is very important to control the alignment and branch.If every time scraping scraping board to a different position, the positioning of the each printing is different.Check whether the scraping board placement positioning is accurate, and can be printed 15 ~ 20 first paper, etc. After drying overprint again.If the image overprint very accurate, scraping board placement agreement;If it is due to shrinkage of paper, printed sheet should be in the front of the printing stroke overprint better, and throughout the entire image from before to after overprint situation worsened;Otherwise, if the other misregister is the case, should be scraping board placement caused by inconsistent.At this point, also can again for the first of two pressure "wet wet overprint operations, then to transfer under a magnifying glass to observe, if there is a double check, if there is a double image, can be sure down the location of the different printing scraping board, must be positioning adjustment again.
