How to debug the screen printing machine?

Today, screen printing machines are the most common in the industry and the latest type of printing equipment in the modern printing industry. Maybe you don’t know the screen printing machine. When we operate the screen printing machine, we should carry out debugging work, so as to ensure the quality of the screen printing product. The accuracy of the adjustment directly affects the accuracy of the printing position of the substrate, then you think the screen printing machine How to debug?

1. Squeegee adjustment

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

2. The adjustment of the parallelism of the ink board to the platform can be adjusted by the screw rods on the left and right respectively. The left and right of the middle rotating shaft with the top screw can adjust the left and right top screw.

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

4. The length of the board can not be adjusted, generally supplied as a kit, each set has several different lengths to choose from.

2. 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.

1. The table and the guide rail should be parallel, and the ink 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 a gap occurs. 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 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.

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.

4. Itinerary 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, the ruler is increased, and the stroke is increased. 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.
