What Is a Cleaning Roller?
A cleaning roller is a rotating roller designed for the removal of dust, dirt, and other foreign particles from board or sheet products.
Products with a flat or sheet-like form, such as circuit boards or paper, are often transported on rollers. The use of a cleaning roller allows for the inline removal of foreign particles without interrupting the product’s movement along the conveyor.
When compared to non-contact dust removal methods, cleaning rollers excel in their ability to eliminate even firmly adhered foreign matter.
Uses of Cleaning Rollers
Cleaning rollers are employed as part of a dust removal system for the conveyance of board-shaped products and the rolling conveyance of sheet-shaped products (web handling).
Examples of sheet products include paper and plastic items.
Cleaning rollers are frequently utilized in clean room environments because the adhesive roller collects foreign particles that may adhere to the roller, thereby minimizing the release of dust.
Principles of Cleaning Rollers
Cleaning rollers consist of a clean roller, which captures foreign particles like dust and dirt, and an adhesive roller, which transfers these particles from the clean roller to itself. Both rollers possess adhesive properties to ensure efficient particle collection, with the adhesive roller exhibiting a higher adhesive force.
After a certain amount of use, the outermost layer of these rollers can be peeled off to reveal a fresh inner adhesive surface. Periodic replacement of the adhesive roller is necessary to remove accumulated foreign particles. Increasing the diameter of the adhesive roller can extend the replacement interval.
Compared to systems that use compressed air to blow off dust or employ a dust collection nozzle for suction, the cleaning roller operates as a contact-based dust removal system, offering the advantage of securely removing dust and other particles that may be strongly attached due to static electricity. However, for delicate products susceptible to scratches, such as materials prone to quality deterioration upon contact with the cleaning roller, non-contact dust removal systems are preferred.
