2. Screen printing machine working process:
Manually place the jig at the feeding end → Print on the front → Dry → Turn the plate → Return to the bottom → Print on the back → Dry → Manually take the jig.

When the whole machine is in continuous production, each plate is coated once, the production cycle is 10-15S/plate to complete the curing, and the equipment can work continuously for 24 hours.
3. Single disk film consistency: Under the condition of sufficient slurry, the relative standard deviation of weight gain in the disk (standard deviation/mean) is ≤5%.
4. Consistency of film layer between each plate: Under the condition of sufficient slurry, the relative standard deviation of weight gain between plates (standard deviation/mean) is ≤10%, or the repeatability of printing is ≤±5um.
5. Applicable product specifications: flat products, product thickness 1-30mm.
6. Parameter control: The angle control accuracy of the scraper and the ink return knife is ≤5 degrees, the height control accuracy of the scraper and the ink knife is ≤0.3mm, and the screen positioning control accuracy is ≤0.5mm.
7. Automation expansion: It can be expanded to automatic material placement, automatic turning, and automatic loading and unloading.
8. Jig: Can be used in continuous production for 1 year without deformation or warping.
9. Transmission control accuracy ≤ 0.1m/min.
10. All conveyors and flip machines can pass through a height of ≥80mm.
11. Maximum printing size: 200×400 mm.
12. Fixture size: 250×460mm (height depends on product thickness)

8. Machine maintenance
① Before going to work, you should clean up the debris on the machine and wipe it clean. Regularly add lubricating grease to the guide rails, guide columns, bearings and other moving parts.
② The work table is a key component that affects the printing quality. It should be prevented from being hit by hard objects. When printing, ink, thinner and other organic solvents should not be dripped onto the work table.
③ The electronic control panel and buttons should be prevented from direct or indirect contact with solvents such as thinner and oil water to prevent damage.
④ The purpose of frame paint is to keep the machine from rusting and to prevent damage caused by direct or indirect contact with solvents such as thinner and oil-opening water.
⑤ The sewage and dirt in the oil mist combiner should be discharged in time to prevent it from entering the pneumatic components and affecting the normal operation. The cup body should be cleaned regularly and lubricating oil should be added to the oil cup of the oil mist combiner .
⑥ When adjusting the flow limiting valve, you must first loosen the locking nut before adjusting it by hand. The handle screw on the machine is used for positioning. After it is firmly positioned, there is no need to tighten it too much.
⑦ After work, turn off the power supply / gas source, clean the screen, and keep it properly to prevent dust / pressure / puncture from hard objects.
