With the continuous development of technology, rotary flexographic printing machines have become an indispensable equipment in the printing industry. However, in order to ensure the normal operation of the printing machine and extend its service life, regular inspection and maintenance are necessary. This article will introduce how to clean and maintain rotary flexographic printing machines after printing, including the cleaning and maintenance of ink rollers and water rollers, as well as the regular inspection and maintenance of the machine.

I. Cleaning and Maintenance of Ink Rollers and Water Rollers

1. Cleaning ink rollers: During the printing process, ink rollers accumulate a large amount of ink. To ensure printing quality, it is necessary to clean the ink rollers regularly. Firstly, use a specialized cleaning agent to thoroughly clean the surface of the ink roller, then wipe it clean with a clean cloth. Note: Avoid using sharp tools to scratch the surface of the ink roller during the cleaning process to prevent damage.

2. Cleaning water rollers: Water rollers play a role in moistening paper during printing, so they also need regular cleaning. Firstly, turn off the water source, then gently wipe the surface of the water roller with a clean cloth or soft brush to remove moisture and impurities. Finally, open the water source and let the water roller air dry naturally.

3. Maintenance of ink rollers and water rollers: To extend the service life of ink rollers and water rollers, regular maintenance is required. The maintenance methods are as follows:

(1) Use a specialized lubricant to lubricate the ink rollers and water rollers to reduce wear and extend their service life.

(2) Apply a protective film on the surface of the ink rollers and water rollers to prevent ink and moisture from corroding their surfaces.

II. Regular Inspection and Maintenance of Machines

1. Check printing quality: Regularly inspect the quality of printed products, such as color and clarity, to ensure that the printing effect meets expectations.

2. Check machine operating conditions: Observe whether there are abnormal sounds, vibrations, or other phenomena during the operation of the machine. If any abnormalities are found, stop the machine immediately for inspection and troubleshooting.

3. Clean machine surfaces: Use a clean cloth or sponge to wipe the surface of the machine, remove dust and stains, and keep it clean.

4. Check electrical systems: Regularly inspect whether the wiring, switches, etc. of the electrical system are in normal condition to avoid damage to the machine caused by electrical faults.

5. Replace wearable parts: According to the usage situation of the equipment, replace wearable parts such as blades and bearings regularly to extend the service life of the equipment.

In summary, the maintenance of rotary flexographic printing machines is crucial. We need to regularly clean, maintain, and inspect them to ensure the normal operation of the equipment and improve production efficiency.
