The screen printing machine is the latest type of equipment in printing enterprises. It is a machine for printing words and images. The screen printing machine is a representative printing equipment among the hole plate printing machines. In the process of use, the accuracy of plate adjustment directly affects the printing position accuracy of the substrate. The following is the version adjustment skills shared by the technicians of Shenzhen yibaolai manufacturer:
1、 Operation adjustment
1. Adjustment of parallelism between guide rail, printing plate and working platform. If the three layers are not parallel, the screen printer can hardly work. Generally, the guide rail or platform is used as the benchmark for adjustment.
a. The platform and the guide rail should be parallel, and the scraping plate moves along the guide rail. If the two are not parallel, the scraper will not always contact the platform with a certain pressure, or even have a gap. This adjustment has been adjusted before the machine leaves the factory.
b. The screen printing plate should be parallel to the platform, otherwise the distance between the screen and the platform is inconsistent, resulting in inconsistent scraper printing pressure and screen printing plate deformation Therefore, the flatness of the screen frame itself should be guaranteed, and the specific requirements of Jianyu screen printing are generally put forward by users according to their needs.
2、 Doctor blade adjustment
1. The adjustment amount of scraper inclination is generally in the range of 65-85 degrees, which can be selected according to needs.
2. The adjustment of printing pressure should be coordinated with the adjustment of the distance between printing plate and printing table. In screen printing, the adjustment of printing pressure is actually the adjustment of the high and low position of the ink scraper.
3. The length of the scraping plate cannot be adjusted. It is generally supplied as a kit, and each set has several different lengths to choose from.
4. The adjustment of the parallelism of the doctor blade to the platform can be adjusted respectively if there are screw rods on the left and right; The left and right jackscrews can be adjusted if there are jackscrews on the left and right of the middle rotating shaft, which is essentially to adjust the quotient low position on the left and right of the doctor blade respectively.
The above version adjustment skills are shared here. The accuracy of version adjustment directly affects the printing position accuracy of the substrate. The printing process is a dynamic process. Due to the changes of various factors, quality problems often occur
