Gravure printing machine manufacturers talk about the inspection process of gravure printing machine
Many people know that after purchasing a gravure printing machine, the first thing is to inspect the equipment. Only after the inspection and inspection work is completed can the contract with the gravure printing machine manufacturer be valid. However, there are still many users who do not know what the inspection process of the gravure printing machine is. Today, gravure printing machine manufacturers will tell you in detail.
The inspection process of the gravure printing machine is mainly divided into two parts, one is the induction function of the whole machine, and the other is the trial operation item.
First, the gravure printing machine machine induction function request
1. The whole machine works smoothly, the transmission system works normally, and there is no abnormal noise.
2, the operating system is reliable, the actuator is accurate, no jamming or spontaneous movement.
3. The electrical system is safe, active and reliable. It is used to request for starting, working and braking during the printing process. The electrical equipment complies with the national standard GB5226.
4. Lubrication system is unblocked, and the gas path system is reliable.
5. The transmission system, boring system and electrical system should have safety protection equipment to ensure the safety of operators and production.
6. The feeding and feeding materials are stable, the traction tension is adjusted, the guiding roller is sensitive to rotation, and the receiving is regular.
7. The pipes and valves of the ink supply system and gas path system should be sealed and outstanding. Ink supply and gas supply are normal.
8. The operating noise is not more than 85dB (A).
9. Appearance quality: It should show that the non-processed appearance should not have stomata, convexity and sag; it should not have rust and bump marks on the surface; blue, electroplated parts, no smears, scratches, etc.; non-processed appearance The paint should be smooth and flat, with the same color.
10. The standard request for the machine is in conjunction with the contract description.
Second, the gravure printing machine trial operation project
1. The printing machine is trial run. Includes no-load test run and load test run.
2. The material roll is connected to the refueling test.
3. Project test of printed products.
