How to debug the automatic screen printing machine?

　　Around us, there are still many companies and individuals who need to use the products of the automatic screen printing machine. Next, let me tell you how to debug the automatic screen printing machine?

　　Squeegee adjustment

　　1. The adjustment of the brushing pressure should be carried out in cooperation with the adjustment of the distance between the printing plate and the printing table. In screen printing, the adjustment of printing pressure is actually the adjustment of the height of the squeegee.

　　2. For the adjustment of the parallelism of the ink plate to the platform, there are screw rods on the left and right to adjust the height and height respectively; those with top wires on the left and right of the middle shaft can adjust the left and right top wires, and the essence is to adjust the left and right positions of the squeegee respectively.

　　3. The adjustment amount of the plate inclination is generally within the range of 65-85 degrees, which can be selected according to the needs.

　　4. The length of the board cannot be adjusted, and it is generally supplied in complete sets, and each set has several different lengths for selection.

　　Adjustment of the parallelism between the guide rail\printing plate and the working platform and the three layers.

　　1. If the three layers are not parallel, the screen printer will hardly work. Generally, the guide rail or platform is used as the benchmark for adjustment. 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 touch the platform with a certain pressure, and even a gap will appear. This adjustment has been adjusted before the machine leaves the factory.

　　2. The screen printing plate and the platform should be parallel, otherwise the distance between the screen and the platform is inconsistent, which will cause inconsistent printing pressure of the squeegee and deformation of the screen printing plate. Therefore, the flatness of the screen frame itself should be guaranteed.

　　Wiping speed adjustment

　　Generally, the adjustment of the entire working cycle is realized through the adjustment handle of the continuously variable transmission device. The speed of each link is guaranteed to be consistent. Each operation adjustment is equipped with a corresponding locking mechanism, and the scraper printing operation must be carried out in a locked state. The installation and maintenance of screen printing machines generally have specific regulations and requirements in the machine instruction manual, and users can refer to the implementation of flat screen printing machines.

　　Stroke adjustment

　　Including the adjustment of stroke size and stroke position. The screen printing machine with crank mechanism and pendulum mechanism can adjust the stroke by adjusting the radius hole position of the crank and pendulum. The ruler increases and the stroke increases. The screen printing machine with pneumatic mechanism can realize stroke adjustment by adjusting the position of the stroke switch. The stroke of the screen printing machine driven by the chain cannot be adjusted.
