Description

Automatic cleaning device for anilox rolls {AUTOMATIC CLEANING APPARATUS OF ANILOX ROLL}

The present invention relates to a roll automatic washing machine capable of washing various types of rolls.

Printing or coating using an anilox roll can be performed by uniformly applying a printing liquid (or coating liquid) to an anilox roll in a printing or coating operation and transferring it by contacting it with a printing engraving or the like.

When the printing or coating operation is finished, it is necessary to wash and remove the ink or coating solution from the anilox roll. Generally, a cleaning solution (eg, N-methyl-2-pyrrolidone solution) is used to clean the surface of the anilox roll. will do

However, in the case of an anilox roll, countless fine cells are formed on the surface, and the ink or coating solution flowing into the cell is not easily removed by simply immersing the roll in a cleaning solution.

In order to wash the ink or coating liquid that has entered the cell, a device for cleaning the anilox roll using ultrasonic waves has been developed, but these devices may cause damage to the roll due to the ultrasonic wave.
