1.The printing rubber roller needs to be cleaned during use, which can not only improve its use effect but also extend its service life. The main steps of the entire cleaning work include:

• 1）First, make sure that there are no remaining work objects in the machine.
• 2）Check whether the paint between the printing rubber rollers and the rubber rollers has basically run out.
• 3）Pour alcohol into a clean empty paint bucket.
• 4）Put a splint or cardboard on the equipment conveyor to prevent alcohol or other solvents from dripping onto the conveyor belt during the cleaning process.
• 5）Start the machine, pump alcohol, and let the alcohol circulate in the machine.
• 6）Enlarge the gap between the two rollers (do not separate the rollers), and adjust the rotation speed to be consistent.
• 7）The alcohol cycle is pumped, and the scraper is manually cleaned after stopping the roller.

2. After shutting down, stop the alcohol cycle, let the alcohol flow on the machine clean, loosen the gap between the steel roller and the rubber roller, close the two rollers, and adjust the speed of the two rollers.
The safety precautions that need to be paid attention to during the whole process include: during the cleaning process of the printing rubber roller, since the paint is basically cleaned by alcohol, there is no lubricating substance between the two rollers, and the friction between the rollers is relatively large. There is a greater possibility of damage, so the gap between the two rollers must be enlarged, but the two rollers cannot be completely loosened. At the same time, in the case of cleaning operation, hands or other foreign objects should not be touched on the running rollers to prevent the running machine from turning hands or other foreign objects into the equipment, causing unnecessary equipment damage and personal injury.
