Micro-fiber Cleaning Plate for Anilox Roll Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Anilox rolls in printing industries face challenges with cell plugging due to dry ink, making them difficult to clean, especially in large presses where access is limited, and existing cleaning methods are either expensive, time-consuming, or require downtime.
Innovation Solution
A micro-fiber cleaning plate with fibers extending from its surface, designed to be installed on a plate cylinder, allowing for in-place cleaning during production, using detergent to scour out dried ink from the anilox roll cells without damaging the delicate cell structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cleaning methods (brushes, blasting, chemicals) are used to clean anilox rolls, then dried ink can be removed from cells, but the delicate cell structure may be damaged or cleaning costs increase
Solution Approach 1:
The patent employs disposable microfiber cleaning cloths that are inexpensive and can be discarded after use. These cloths are saturated with cleaning solution and used to gently wipe the anilox roll surface, removing dried ink without the need for expensive equipment like blasting machines or specialized chemical systems. The disposable nature ensures no contamination from reused materials while keeping costs low.
Solution Approach 2:
The patent changes the physical parameters of the cleaning approach by using microfiber cloths with specific fiber dimensions that are softer than the anilox cells. The cleaning solution parameters are also optimized to dissolve dried ink effectively. This combination allows gentle cleaning that preserves cell integrity while maintaining cleaning effectiveness.
2Reliability
If the anilox roll is removed from the press for cleaning, then thorough cleaning can be performed, but production downtime increases
Solution Approach 1:
The patent enables preliminary cleaning actions to be performed during production runs. The microfiber cloths saturated with cleaning solution can be applied to the anilox roll while it remains in the press, allowing cleaning to occur during normal operation or brief maintenance windows without requiring roll removal. This preliminary action prevents complete plugging before it occurs.
Solution Approach 2:
The cleaning system is designed to be self-contained and portable, allowing operators to perform cleaning tasks independently without requiring press shutdown or specialized equipment. The microfiber cloths with cleaning solution can be applied directly to the roll in place, enabling the system to service itself during operation.
3Ease of operation
If brushes are used to clean anilox rolls, then dried ink can be removed, but the bristles may be larger than cells and fail to reach inside, potentially leaving ink deposited within cells
Solution Approach 1:
The patent uses flexible microfiber cloths that can conform to the cylindrical surface of the anilox roll and penetrate into the cell structures. The thin film nature of the microfiber material allows it to reach into cells that rigid brush bristles cannot access, while the flexibility enables the cloth to wrap around the roll surface for complete coverage.
Solution Approach 2:
The microfiber cloths have a porous structure with fibers that can enter and reach into the anilox cells. The porous nature of the material allows cleaning solution to penetrate deep into cell structures and carry dissolved ink away, providing effective cleaning where solid brush bristles would bounce off or fail to reach.
4Loss of time
If in-place cleaning methods are used, then downtime is reduced, but access to the roll is limited by surrounding press components
Solution Approach 1:
The patent divides the cleaning task into manageable segments by using portable microfiber cloths that can be applied to different sections of the anilox roll independently. This segmentation allows cleaning to proceed in zones around the press components, navigating around obstacles rather than requiring complete access to the entire roll at once.
Solution Approach 2:
The patent approaches the cleaning problem from another dimension by using flexible, conformable cloths that can wrap around the cylindrical roll and access surfaces from multiple angles. This dimensional approach allows cleaning in confined spaces where traditional linear cleaning tools cannot reach, utilizing the three-dimensional flexibility of the microfiber material.

Function Achieved in This Case
The micro-fiber cleaning plate provides a cost-effective, downtime-free method to maintain anilox rolls, extending their life and improving print quality by effectively removing dried ink from the cells without causing damage, thus reducing pinholes in printed materials.
Implementation Method 1
micro-fibers on the surface of the micro-fiber cleaning plate come into contact with the cells of the anilox roll and scour out dried ink
Implementation Method 2
micro-fibers on the surface of the micro-fiber cleaning plate come into contact with the cells of the anilox roll and scour out dried ink
Implementation Method 3
A detergent cleaner may be used in substitution for the ink to further assist the cleaning action
