Problems solved by technology
[0004] In order to completely solve the traditional two-roller coating of color-coated metal sheets, only low-viscosity coatings can be used and the lack of corresponding adjustment and control technology causes poor coating surface decoration effects and traditional three-roller and four-roller coating process systems and technologies. High labor intensity, low production efficiency and color difference between front and back of the same product caused by complexity, coating with solid content coatings of different particle sizes and transparent, translucent bright color coatings are prone to roll marks, horizontal lines and coating molecular agglomeration back to coarse particle pull lines etc., the present invention provides a combination of the advantages of simple and efficient two-roller coating and three-roller and four-roller coating with exquisite surface coating decoration effect, and overcomes the traditional two-roller coating and three-roller and four-roller coating at the same time. High-precision two-roller coating system and coating method for color-coated metal sheets with technical defects in roller coating

Embodiment Construction
[0014] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0015] On the one hand, the present invention provides a kind of high-precision two-roller coating system of color-coated metal plate, such as Figure 1 ~ Figure 2 As shown, in the space on the side of the metal strip that needs to be painted, a paint tray 1, a fine thread paint pick-up roller 2 and a coating roller 3 are arranged in sequence along the paint conveying direction, and a scraper 4 is arranged on the fine thread paint pick-up roller 2 ; The space behind the coated surface of the metal sheet is provided with a backing roller 5 . During coating production, the coating roller 3 acts on the backing roller 5 with an appropriate pressing force, so that the paint on the coating roller 3 is transferred to the metal that passes through the gap betwee...

The invention discloses a high-precision two-roller coating system for a color coated metal plate and a coating method of the high-precision two-roller coating system, and belongs to the technical field of metal plate strip color coating. The high-precision two-roller coating system for the color coated metal plate is sequentially provided with a coating plate, a fine threaded coating picking roller and a coating roller in the direction of coating conveying in the space of the side, to be coated, of a metal plate strip. A backing roller is arranged in the space of the reverse side of the coated side of the metal plate strip. The fine threaded coating picking roller is provided with a scraper, rigid material and flexible material of the scraper can be interchanged according to the coating property, and the scraping angle, clearance and pressure of the scraper with the roller surface of the fine threaded coating picking roller can be adjusted arbitrarily. The diameter of the coating roller is smaller than that of the backing roller, and the backing roller is the coating pressure bearing roller when the metal plate strip is coated. The advantages of simplicity and high-efficiency of two-roller coating and exquisite decoration effects of surface coatings of three-roller and four-roller coating are combined, and defects of respective processes of the traditional two-roller coating and three-roller and four-roller coating are overcome.
Description
technical field [0001] The invention relates to the technical field of color coating of metal strips, in particular to a high-precision two-roller coating system for color-coated metal plates and a coating method thereof. Background technique [0002] Color-coated metal sheets are more and more widely used in all walks of life and fields because of their light weight, anti-corrosion, toughness and durability, excellent craftsmanship and beautiful decorative effects. However, the most simple and efficient two-roller coating technology currently available is only suitable for low-viscosity coatings due to its simple process technology, lack of necessary adjustment and control means, and poor leveling effect of high-viscosity coatings. It is used for the primer coating of color-coated products or the back-coating and printing of very thin paint films, as well as the production of general color-coated products that require less decorative effects on the coating surface. For col...
