High-speed electronic axis rotary gravure printing machine in the maintenance need to pay attention to the following key matters to ensure the stable operation of the equipment and extend the service life:
1. Daily cleaning and maintenance
Regular cleaning: at the end of every day, a soft cloth or brush should be used to clean the printing plate, cavity and rotating parts to remove residual ink and impurities. At the same time, the filter and oil system should be cleaned regularly to keep the equipment clean.
Roller maintenance: pay attention to the amount of ink carried by the roller, often wipe or wash the roller with high pressure jet to prevent ink drying and blocking. For bad ink impurities are more likely to cause blockage problems, should be filtered before use.
2. Component inspection and replacement
Key parts inspection: Regularly check the key parts of the equipment, such as ink delivery device, printing unit, circuit system, etc., to ensure that it is in good working condition. Pay special attention to check the wear of the ink roller, rubber roller, scraper, press roller and other parts, and replace the badly worn parts in time.
Parallelism and gap adjustment: Regularly check the parallelism and gap of the gravure press, such as the gap between the ink roller and the rubber roller, which should usually be between 0 and 0.5mm. Keep the parallel degree of the scraper seat, and adjust by professional technicians when the accuracy requirements are high.
Three, lubrication system maintenance
Lubricating oil inspection: Check the condition of lubricating oil regularly to ensure the normal operation of the lubrication system. Replace the lubricating oil when necessary to maintain the smooth operation of the equipment.
Iv. Electrical systems and safety
Electrical circuit inspection: Check the electrical circuit of the equipment regularly to ensure its safety and reliability. Avoid equipment downtime or safety incidents caused by electrical faults.
Safety protection: Pay attention to safety during operation and wear relevant protective equipment to prevent accidental injury. Keep it clean around the machine and avoid the accumulation of combustible materials such as waste paper to prevent the occurrence of fire.
5. Reasonable operation and rest
Operation plan: Make a reasonable operation plan according to the actual situation and operation requirements of the equipment. Avoid equipment fatigue and failure caused by long-term continuous operation.
Cooling and relaxation: If the machine runs for too long, it should be cooled and relaxed to prevent damage or failure of the machine.
6. Professional training and exchange
Professional training: Maintenance personnel should receive relevant training to understand the structure and performance of the equipment, and master the knowledge and skills of maintenance.
Technical communication: Communication with suppliers and other maintenance personnel is also important. Keeping abreast of the latest maintenance technologies and experience sharing can help maintenance personnel better manage and maintain printing equipment.
7. Establish maintenance and maintenance system
Regular inspection system: Establish a regular inspection system every day, every week, every month and every year to carry out a comprehensive inspection of all parts of the equipment, and find and solve problems in time.
Maintenance and repair records: Establish detailed maintenance and repair records, record each maintenance and repair time, content, replacement parts and other information for future reference and tracking.
