Core Component Maintenance
Transmission Gearbox: Monitor lubricating oil level and temperature. Replace the oil promptly if it becomes cloudy. Never operate the machine at high speed without lubrication to avoid gear damage.
Anilox Rollers: Prevent impacts. Clean immediately after printing to prevent ink clogging of the cells. Regularly check the wear of the bearings at both ends. Replace the bearings promptly if the circumferential runout exceeds the limit. Ensure the runout value of the three rollers does not exceed 0.02mm.
Shuttle Blade System: Replace promptly when worn. After each printing session, disassemble and clean the blade holder and pressure bar to remove residual ink. Wipe the blade edges with alcohol and allow them to dry to prevent rust and avoid uneven blade edges that may cause ink marks.
Lubrication and Maintenance: Select the appropriate lubricant according to equipment requirements: For high-speed bearings, choose a high-dropping-point grease (such as sodium soap or lithium soap-based grease) to improve high-temperature protection; Bearings that may come into contact with water must use a water-resistant calcium soap/lithium soap-based grease to prevent bearing corrosion and shorten lifespan; Strictly follow the manufacturer's requirements to select a grease with the appropriate hardness to avoid insufficient lubrication or increased resistance.
Precision Calibration: Regularly check and adjust the parallelism of the printing plate cylinder, impression cylinder, and guide rollers: The parallelism error of each roller in the same color group should not exceed 0.03mm, and the error between adjacent color groups should not exceed 0.05mm to avoid problems such as misregistration and wrinkling.
