Cleaning Device for Coating Rollers

Technical Field The utility model belongs to the technical field of coating equipment, and particularly relates to a cleaning device for coating rollers.

Description of Related Art Coating rollers are used to coat various substrates, such as paper, paperboards, plastic films, foil, metal plates, glass plates, and wooden boards, with coating to prepare different substrate films. There are many types of coating rollers, and anilox rollers are the most common ones. The anilox rollers, as the core part of ink delivery o devices of presses and the "heart" of flexographic presses, are initially and most widely applied to printing equipment to determine the quantity of transferred ink, and are key components for controlling the ink film thickness. As a matter of fact, the anilox rollers are also used in various coating apparatus industries. For example, in the pressure-sensitive adhesive industry, the anilox rollers are used to supply pressure-sensitive adhesives to be applied to surface materials. The anilox rollers need to be cleaned after being used for certain times or when coating roller consumables are changed. At present, the coating rollers are typically cleaned in such a manner: the coating rollers are directly placed in a container containing a cleaning solution, then adhesives on the surfaces of the coating rollers are manually removed with non-dust cloth, and after being cleaned, the coating rollers are wiped with non-dust cloth and are then vertically hanged on supports. Meanwhile, in consideration of the high price of the coating rollers, the surface of the coating rollers is generally wrapped with a flexible buffer layer in the cleaning process to prevent the coating rollers against dust and to protect the coating rollers against deformation or surface scratches caused by other objects or mutual collisions, which may otherwise scratch the film and affect product quality.
