Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of roll coater relates to a paint steel glue dual -purpose roll coater. BACKGROUND

[0002] The most important step in the production process of color-coated aluminum coil is coating the aluminum coil, so that the surface is covered with paint with protective function, improving the weather resistance and aesthetics of aluminum materials.

[0003] At present, the industry has different specifications of color-coated aluminum coil, which usually uses different equipment according to the thickness. The aluminum coil with a thickness of 0.016-0.15mm is coated with a steel roller, and the aluminum coil with a thickness of 0.15-3mm is coated with a rubber roller. Because the two ways of coating have advantages and disadvantages, many customers hope to have a coating machine that can coat both ways, so that thick and thin aluminum coils can share a production line. At present, the production line for thin aluminum is coated with a steel roller, and the production line for thick aluminum is coated with a rubber roller, which inevitably causes resource waste and increased investment.

[0004] A Chinese utility model patent discloses a two-in-one coating machine of steel coating roller and rubber coating roller, which comprises an L-shaped rack, a control roller is arranged on the front table of the rack, a steel coating roller is arranged above the control roller, a rubber coating roller is arranged above the steel coating roller, a paint lifting roller is arranged on the front side of the steel coating roller, a pressing roller one is arranged on the rack behind the steel coating roller, a pressing roller two is arranged on the rack behind the rubber coating roller, an aluminum coil is arranged between the steel coating roller and the pressing roller one and between the rubber coating roller and the pressing roller two, the pressing roller one and the pressing roller two move forward and backward under the drive of a power device, and the rubber coating roller moves up and down under the drive of the power device.
