1. The single color pad printing machine power adjustment
Air supply device is a combination of pneumatic valve, it ensures the opening of the gas source on and off, and clean air source pressure stability.The 110 v power source is 220 v power supply (special circumstances) power supply voltage should be stable.
2. The installation of the steel plate
Steel is the source of substrates by, so the key to adjust for pad printing technology, graphic monochrome version and chromatograph.
A. monochrome version: the steel plate, plastic head fixed in the middle of the oil pot, glue head first combination, make the glue head is roughly in the middle of alignment design, oil pot, workbench, pipe again, make the rubber head on the substrates were printing position.
B. chromatograph: installed steel plate, plastic top again after adjusting the adjustable oil basin, plastic head combination and workbench, so that the graphic overprint accurate.Can be adjusted the first piece of steel plate and the location of the substrates, and then to consult individually adjust its tablets.
Multi-color overprint color block overprint color overprint (including four-color overprint).Pad printing process printing depending on the color of the substrates, can jump a layer of white, multi-color overprint, again in order to improve the degree of colorful color graphic, for four color overprint (folding color overprint) should pay special attention to the steel plate graphic printing sequence, the general department to arrange for the green, magenta, yellow, black,Color piece of multi-color overprint (color overprint), the general requirements of shallow first printing, printing after dark, if quality is bad arrangement to print out the required effect.Part of the installation of the chromatograph are divided into coarse and fine tune two step, to all kinds of graphic overprint overlap, can print out the clear picture and text shall prevail.
Installing a steel plate, also should pay attention on long, fine lines, and the scraper should as a certain Angle, avoid the scraping blade whereabouts to the steel plate by sunken place, ink is too much away, affected by quality.
3. The blade adjustment
Is the role of scraper by residual ink scrape on the steel plate, scraper bad contact with steel plate, therefore, squeegee pressure stroke adjustment improper and so on will affect the graphic print effect.
A..Blade: its width, compared with steel plate by unilateral should be more than 3 mm wide, but not more than the steel plate width.Blade toughening mouth not sharp fine sandpaper grinding are available, and if the gap to replace, the blade should be in steel plate above 3-5 mm.
B. pressure: too small cannot will ink scrape, too much could scrape blade, steel plate or damage to the concrete numerical value depending on the model, monochrome machine the required pressure is lesser, two-color, three color will increase in turn.Before starting, pressure regulating valve must be zero.
C. schedule: will be subject to steel plate by size.
4. Glue head adjustment
Pressure is too small, cannot print the graphic to produce defects, stress is likely to cause in the process of stained with ink printing ink extrusion, mobile, uniform ink cannot be attached to the rubber head the resulting in printing graphic fuzzy or with white dots.
In addition, the center of the rubber head pressure in no or less best line of steel in the graphic, in order to avoid the glue head center, due to the large pressure to form a white dot.
Pad printing pressure in the adhesive and the ink amount of compression head, generally choose the graphic to complete the transfer printing, rubber head of longitudinal compression quantity should be about 10 mm.
5. Ink deployment
Should see a circumstance to the original ink and thinner in allocate, after mixing ink concentration dilution degree and has much to do with the graphic effect after printing.If the concentration is too thin will make talk and fuzzy graphic color, too thick will cause shortage of graphic lines and adhesion to drop again.
In India, the following three points should be pay attention to:
A. ink deployment should be fully dissolved after just can use,
B. after mixing the original ink deposit shall cover and a cool and dry place,
C. if oil machine, because the oil basin of the leakage evaporating faster, so according to need timely and diluent.
On the issue of the ink dry, as a result of the pad printing speed stalwart, so ink can rapid drying.In 2 to 5 seconds, dry ink called quick dry ink;Drying should be more than 5 seconds it is called a slow dry ink.If the ink drying speed is slow can't meet the printing speed will produce with color, which affects the printing effect, such as requirements overprint speed, when necessary, through the method of the wind cold (or hot) to dry ink in a timely manner.
6. A positioning device (substrates) tube
D. tube production: shape the rules substrates (workpiece) through a pin, border and USES the way such as fast clamping clamp;Irregular workpieces by using crystal made of rubber and gypsum plaster to locate.
E. pipe a correction: a qualified, use testing-run to test to pass, when it is necessary to for repair and correction, to meet the requirements of printing house need positioning.
7. Pay attention to the single color pad printing machine installed correctly
Single color pad printing machine installed correctly and the use of science, can prolong the service life of it, you can ensure that pad printing machine to maintain good state and keep high precision printing.
Single color pad printing machine during installation to leveling, workbench plane as a benchmark to install in formation on solid ground, in order to reduce the vibration stability.
