Ultrasonic Cleaning Machine For Roller

 

An ultrasonic cleaning machine for anilox rollers is a specialized piece of industrial equipment designed to clean the anilox roller and micro roll used in flexographic printing. Unlike standard cleaners, these machines are built to handle the specific shape, size, and delicate surface of rollers..

 

The machine operates on the principle of cavitation-using high-frequency sound waves to create and collapse millions of microscopic bubbles in a cleaning solution. For anilox rollers specifically, these machines have several key features:

Suspension Design: The roller is suspended or mounted on a swiveling wheel within the tank, allowing it to rotate and ensure all the tiny ink cells (which can be as small as a few microns) are evenly exposed to the cleaning action.

Dual-Frequency Capability: Many models offer both single and dual-frequency options. For example:

Single Frequency (e.g., 40 kHz): Provides stable, thorough cleaning for general maintenance.

Multiple Frequencies: Allows you to start with a lower frequency to dislodge stubborn, dried-in ink, and then switch to a higher frequency for a final, precision clean.

Heated Tanks: Built-in heaters (often around 1000W) warm the cleaning solution to an optimal temperature. Warm water and a specialized cleaning agent significantly enhance the cavitation effect and speed up the process.

Stainless Steel Construction: The tanks are typically made from robust materials like SUS304 stainless steel to resist corrosion from cleaning solvents and provide long-term durability

Key Features to Look For

*Adjustable Frequency: A machine with dual or multiple frequencies offers the most versatility for different levels of contamination and roller delicacy.

*Heating System: This is essential for effectively breaking down cured inks and solvents. A constant temperature system is a major plus.

*Roller Rotation Mechanism: Look for a model with a swiveling wheel or rotating mechanism to ensure the entire roller surface is cleaned evenly.

*Proper Sizing: Machines are often custom-built to accommodate the specific length and diameter of your anilox rollers

Before You Buy

*Inspect Your Rolls First: Closely examine your anilox rollers for any existing cracks, chips, or signs of wear. Do not use an ultrasonic cleaner on damaged rolls, as the process will likely ruin them.

*Use the Correct Solution: Tap water alone is not enough. Use a specialized cleaning agent or solvent designed for ultrasonic cleaning of anilox rolls.

*Consider Automation: For larger operations, look for models with PLC controls for automated, repeatable cleaning cycles
