Plastic Cup Screen Printing Machine

A: The plastic cup screen printing machine can print a variety of plastic cups, such as the common disposable water cups made of polypropylene (PP) and polyethylene (PE), and milk tea cups made of polystyrene (PS).

A: The daily maintenance of the plastic cup screen printing machine should focus on the cleaning of the screen, and clean the residual ink in time after use to prevent the mesh from clogging and affecting the next printing. Check the scraper wear regularly and replace it in time to ensure uniform ink coating. Mechanical parts need to be lubricated regularly, such as guide rails, transmission chains, etc., to ensure smooth operation of the machine. In addition, the circuit system should also be checked to avoid failures caused by aging of the line.

A: The plastic cup screen printing machine can achieve multi-color printing. Complex patterns are completed by overprinting different color inks multiple times. After each color is printed, it is necessary to wait for the ink to dry or use a quick curing method before accurately aligning the next color.

A: The thickness can be controlled by adjusting the scraper angle, pressure and ink viscosity. When the scraper angle is small and the pressure is high, the ink thickness is relatively thin; otherwise, it is thick. The ink viscosity is high and the thickness increases. The appropriate ink thickness can ensure that the pattern is full of color and the drying speed is reasonable, avoiding problems such as ink accumulation and slow drying due to excessive thickness, or unsaturated color and insufficient covering power due to excessive thinness.

A: The working environment of the plastic cup screen printing machine should be kept clean, dry and well ventilated. Too much dust may mix into the ink and affect the printing quality. A humid environment may change the ink performance or rust the machine parts. The suitable temperature range is generally 20-25℃. Too high or too low temperature may affect the fluidity and drying speed of the ink. Ventilation helps the ink smell to be dispersed and the gas to be discharged during the drying process.

A: The plastic cup screen printing machine can print on the surface of a curved plastic cup. It is equipped with a special fixture or turntable that can fix and rotate the cup so that the screen plate and the cup surface maintain a suitable contact angle and pressure during printing. By adjusting these devices, it can adapt to cups of different curvatures, ensure that the ink is evenly attached to the surface of the cup body, and achieve complete and clear pattern printing.

A: If ink leakage occurs, first check whether the screen plate of the plastic cup screen printing machine is damaged or the mesh is too large. If so, it needs to be repaired or replaced. Secondly, check whether the scraper is flat and the pressure is uniform. Uneven pressure may cause ink leakage, and the scraper needs to be adjusted or the pressure parameters need to be reset.

A: The plastic cup screen printing machine can print special effect patterns. By using special inks, such as luminous ink, luminous effect can be presented in the dark; the use of metallic texture ink can simulate the metallic luster.

A: When operating the plastic cup screen printing machine, prevent the ink from contacting the skin and eyes, and wear protective gloves and goggles. When the machine is running, it is strictly forbidden to put your hands or other objects into the printing area to avoid injury. Regularly check the insulation of electrical equipment to prevent leakage accidents. Properly store flammable items such as inks and solvents, away from fire and heat sources, ensure the safety of the production environment, and avoid dangerous situations such as fire.

A: LED UV drying for plastic cup screen printing machine uses LED light source of specific wavelength to stimulate UV ink curing, which has low energy consumption, less heat, fast curing speed and environmental protection. Electric UV drying usually uses traditional mercury lamps to generate ultraviolet rays, which has stable curing effect but relatively high energy consumption and high heat generation.
