Pad printing machine basic operating procedures

1. Before starting the pad printing machine each time, check the scraper part and the glue head part, which must be in the starting position; check the circuit part for no leakage; check the air circuit for no air leakage;

2. Turn on the circuit switch, the display on the panel should be able to display normally; turn on the air switch to ensure that the pressure of the air pressure gauge of the whole machine reaches 5~7 kg/cm², and the pressure gauge of the scraper barometer should be able to display normally.

The pressure reaches about 2 kg/cm² (subject to the pad printing blade being able to scrape off the ink);

3. During the operation of the pad printing machine, it is strictly forbidden to put your hand between the relatively moving parts to prevent pinching;

4. When placing the pad printing steel plate in the oil pan, the anti-rust oil on the steel plate must be wiped clean, and the contact surface between the steel plate and the oil pan must be checked so that the two can be fully fitted;

After using the pad printing plate, the ink must be wiped clean, and anti-rust oil should be applied on the surface to prevent rust;

5. After installing the ink roller for applying ink, the pad printing plate must be placed in the oil pan, otherwise it will be hung up during the running process;

6. It must be ensured that when the pad printing blade moves back and forth on the steel plate, both the front drop knife and the rear start knife must be on the surface of the steel plate, and are not allowed to fall outside the steel plate to prevent the knife edge from being injured;

7. The amount of ink added to the oil pan must be enough to completely cover the pattern on the steel plate when the ink roller returns to ink;

8. The ink must be diluted with solvent. Too thick or too thin will affect the printing effect. According to the climate and the process characteristics of the workpiece, choose slow-drying water or fast-drying water;

9. According to the shape of the printed workpiece, select the appropriate pad printing pad, including the shape and hardness of the pad;

10. Use the two knobs on the side of the beam on the right to adjust the height of the glue head above the steel plate and the workpiece: Above the steel plate, the height of the glue head should be able to completely cover the pattern ink.

The height of the glue head should be able to completely deprint the pattern ink on the workpiece, and the deformation of the glue head should not be too large;

11. The mode value on the panel must be set correctly, the wrong setting will make the pad printer unable to operate normally;

 12. The front, rear, upper and lower guide posts on the pad printing machine must be lubricated with oil once every 6 months to ensure that the moving parts can operate easily;

13. Most of the parts used on the pad printing machine are aluminum products, so when tightening the screws, you should use appropriate force, any excessive force may cause the screws to slip;
