Gravure / die-cutting question and answer

Q: What if the computer operation panel shows a blank?
A: The main problem is the computer hardware. Please contact our factory in time for after-sales service.
Q: Why does a certain color match one direction?
Answer: The problem is mainly longitudinal correction. It may be that the key is not installed or the plate is not loaded during loading. Please reinstall or relock the plate.

Q: Why do you print horizontally?
Answer: The main reasons are:
1. Film printing performance is not good. 2. The guide roller is stained with ink. 3. Printing drying temperature setting is too high. 4. The amount of hot air is too high.
5. Improperly set the print tension. 6. The machine is faulty.
The solution is:
1. Use specifications printed film. 2. Scrub the guide roller. 3. Set the appropriate printing drying temperature. 4. Adjust the appropriate printing air volume.
5. Set the appropriate printing tension. 6. Contact with our factory, maintenance and debugging.

Q: Why is the trapping motor not operating and how to solve it?
A: The main reasons are: 1. The power of the trapping motor is not turned on. 2. The chromatographic driver board is damaged. 3. Bad connection of the chromatographic connector. The solution is: 1. Turn on the color filter motor power. 2. Replace the color drive plate. 3. Connect the color connector connector.

Q: Why does the main motor not start and how to solve it?
Answer: The main reasons are: 1. Emergency stop self-locking did not open. 2. The inverter start switch is broken.
The solution is: 1. Loosen the emergency stop self-locking. 2. Switch on the inverter start switch wiring.

Q: Why does the automatic stop and automatic start of the main motor run and its solution?
A: The main reason is that the inverter's speed control potentiometer is used with poor performance.
The solution is: replace the new frequency control potentiometer.

Q: The cause of the instability of printing tension and the solution?
A: The reasons are: 1. The inflation shaft is not inflated and the film is not locked. 2. The film itself has poor tensile properties or the film has too much eccentricity.
The solutions are: 1. Air inflation shaft seals the printed film. 2. Use the printed film to install the film.

Q: Why does the temperature of the temperature control switch not reach the set printing temperature and the solution?
A: The reasons are: 1. The solid state relay is damaged. 2. Set the temperature below ambient temperature.
The solution is: 1. Replace the solid state relay. 2. Set above ambient temperature.

Q: The temperature control switch can't reach the temperature and the solution to set the high temperature?
Answer: The reasons are: 1. The misoperation setting exceeds the ambient temperature °C. 2. Temperature control switch gear setting is low. 3. The throttle is too big. The solution is: 1. Set at an ambient temperature of 30-40 °C. 2. Improve the temperature control switch gear. 3. Adjustable
