Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a coating roller device. Background Art

[0002] At present, in the process of steel production, a variety of roller coating machines are used, including single-roller coating machines, two-roller coating machines and three-roller coating machines, such as single-roller coating machines are used to coat silicon steel with magnesium oxide in silicon steel production, two-roller coating machines and three-roller coating machines are used to coat insulation layers, and roller coating machines are used to coat passivation liquid in carbon steel galvanizing units. The structure of the single-roller coating machine in silicon steel production is: there is a coating roller on the upper and lower sides of the strip steel, the lower coating roller rises during production, contacts the upper coating roller, sprays the coating liquid at the entrance of the strip steel, there is a coating liquid pan filled with coating liquid under the lower coating roller, the lower part of the lower coating roller is immersed in the coating liquid of the coating liquid pan, and the thickness of the coating film on the strip steel is adjusted by adjusting the extrusion force of the upper coating roller and the lower coating roller. However, the height of the coating pan of a single-roll coater is generally fixed. Over time, magnesium oxide will deposit and agglomerate in the coating pan. When the agglomerates reach a certain height, they will interfere with the lower coating roller, causing friction and damage to the rubber layer of the lower coating roller. At the same time, the immersion depth of the lower coating roller in the coating pan will also affect the dipping of the lower coating roller. If the lower coating roller is immersed too shallowly in the coating pan, the lower coating roller will dip less and affect the coating film thickness. If the immersion is too deep, the coating pan and its accessories will easily interfere with the lower coating roller and its accessories that are lifted up and down. Similar problems also exist in other roller coaters such as two-roll coaters and three-roll coaters, namely, whether the immersion depth of the dipping roller and the coating pan is reasonable, and because the roller is close to the coating pan, interference may occur when the roller is replaced. Therefore, it is necessary to make improvements to properly solve the above problems. Utility Model Content
