1. The maintenance of the offset printing machine should be based on the machine's manual. Such as regular oil change, filter cleaning, regular inspection of machine accuracy, etc. 2. Strengthen the maintenance of important parts. Gears, cams, sprockets, rollers, and bearings are the most important parts of the printing press. Their maintenance should be different from other parts, because their accuracy changes will affect the final. Springs are the most commonly used parts for force balancing mechanisms on machines. Their working quality directly determines the accuracy of the matching of moving parts. The springs must be sensitive and elastic, and the aeroelasticity and irreversible plastic deformation affect the work of the spring. Extremely disadvantageous. If you find the above problems, you need to replace the spring immediately. The hazards of solvent residues in the printing process. 3. Carry out technical reforms and strengthen machine maintenance. Machine maintenance requires the convenience of machine maintenance in the design of the machine. However, due to the complexity of the printing press, it is obviously impossible to take every factor into account, and the content of machine maintenance will also change as the environment changes. Therefore, those structures that are not conducive to machine maintenance should be improved without affecting normal work.
