The screen printing machine is also one of the screen printing machines, and it is also the latest type of equipment in the printing enterprise. It is a machine for printing text and images. The screen printing machine is a representative printing equipment in the stencil printing machine. In the process of use, the accuracy of the adjustment directly affects the accuracy of the printing position of the substrate, so what are the adjustment methods of the screen printing machine? The following is introduced by everyone:

1. Adjustment of the parallelism between the three layers of the guide rail, printing plate and working platform. If these three layers are not parallel, the screen printer will almost not work. Generally, the guide rail or platform is used as a reference for adjustment.

①The platform and the guide rail should be parallel, and the squeegee plate moves along the guide rail. If the two are not parallel, the squeegee will not always contact the platform with a certain pressure, or even a gap occurs. This adjustment has been adjusted before the machine leaves the factory.

②The screen printing plate and the platform should be parallel, otherwise the screen distance is inconsistent, causing the scraper printing pressure and the screen printing plate deformation to be inconsistent. Therefore, the flatness of the screen frame itself should be guaranteed. Jianyu screen printing is generally proposed by the user according to needs Specific requirements.

2. Squeegee adjustment

① The adjustment of the parallelism of the squeegee to the platform can be adjusted separately by the screw rods on the left and right; the left and right top screws can be adjusted on the left and right of the intermediate shaft. The essence is to adjust the low position of the squeegee on the left and right.

②The adjustment amount of the inclination angle of the scraper is generally within the range of 65-85 degrees, which can be selected according to the needs.

③ The adjustment of printing pressure should be coordinated with the adjustment of printing plate and printing table distance. In screen printing, the adjustment of printing pressure is actually the adjustment of the height of the squeegee.

④The length of the scraper board cannot be adjusted. Generally, it is supplied as a kit. There are several different lengths for each set.

3. Adjust the scraping speed.

Generally, the adjustment handle of the stepless speed change device is used to adjust the size of the entire working cycle. It is guaranteed that the speed of each link is consistent. Each kind of adjustment is equipped with a corresponding locking mechanism, and the printing operation of the doctor blade must be carried out in a locked state. The installation and maintenance of the screen printing machine generally have specific regulations and requirements in the user manual of the machine, and the user can refer to the implementation. Stroke adjustment. Including adjustment of stroke size and stroke position. The screen printing machine adopting the crank mechanism and the swing lever mechanism can realize the stroke adjustment by adjusting the radius positions of the crank and swing lever, and the ruler increases and the stroke increases. The screen printing machine adopting the pneumatic mechanism can realize the stroke adjustment by adjusting the position of the stroke switch. The stroke of a screen printer driven by a chain cannot be adjusted.
