Screen printing machine is also a kind of screen printing machine and the latest equipment in printing enterprises. It is a machine for printing words and images. Screen printing machine is a representative printing equipment in the hole plate printing machine. In the process of use, the accuracy of plate adjustment directly affects the printing position accuracy of the substrate. What are the adjustment methods of screen printing machine The staff of Shenzhen yibaolai factory introduced:


1、 Adjustment of parallelism among guide rail, plate and working platform. If these three layers are not parallel, the screen printing machine can hardly work. Generally, the guide rail or platform is used as the reference for adjustment.


① 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.


② The screen printing plate and the platform should be parallel, otherwise the screen platform distance 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 user generally puts forward specific requirements for Jianyu screen printing according to the needs.


2、 Scraper adjustment


① The adjustment of the ink scraper to the parallelism of the platform can be adjusted by adjusting the height of the left and right screw rods respectively; the adjustment of the left and right jackscrews with jackscrews on the left and right of the middle rotating shaft can be adjusted, which is essentially to adjust the quotient low position of the left and right ink scraper plates respectively.


② The angle adjustment of scraper is generally in the range of 65-85 degrees, which can be selected as required。


③ The adjustment of the printing pressure shall be carried out in coordination with the adjustment of the distance between the printing plate and the printing platform. In screen printing, the adjustment of printing pressure is actually the adjustment of the height position of the scraper.


④ The length of the scraper plate cannot be adjusted。 Generally, it is supplied as a set。 Each set has several different lengths to choose from。


3、 Adjustment of scraping speed.


Generally, the adjustment of the whole working cycle is realized by the adjusting handle of the CVT to ensure the speed of each link is the same。 Each kind of pushing adjustment is equipped with corresponding locking mechanism, and the scraper printing operation must be carried out in the locked state。 The installation and maintenance of the screen printing machine are generally specified and required in the operation manual of the machine。 Users can refer to it for implementation。 Travel adjustment。 Including stroke size and stroke position adjustment。 The screen printing machine with crank mechanism and swing bar mechanism can adjust the stroke by adjusting the radius and hole position of crank and swing bar。 The pneumatic screen printing machine can adjust the stroke by adjusting the position of the stroke switch。 The stroke of the screen printing machine driven by chain cannot be adjusted。
