A coating device for coloring with a combined color changing roller

Abstract

The invention discloses a coating device for coloring with a combined color changing roller, which comprises a coating distribution component, a coating component, a cleaning component, a drying component, a conveying component, a lower frame, an upper frame, and an upper frame The lower surface is tightly connected with the upper surface of the lower frame, the paint distribution component, the coating component and the side wall of the upper frame are fastened, the cleaning component is installed on the coating component, the drying component, the conveying component and the lower platen of the upper frame The upper surface is tightly connected, and the paint distribution assembly of the present invention promotes the uniform diffusion of the color masterbatch through the rotating ring, avoiding the local color depth of the paint colloid when the color masterbatch dissolves, and ensuring the color uniformity of the base film after coating . The coating assembly of the present invention avoids the need for multiple color coating rollers through the combined use of color changing rollers and color changing blocks, and realizes the color changing process on a single color changing roller, and at the same time realizes the smoothness of the color changing process. shutdown.

Description

technical field [0001] The invention relates to the technical field of coating, in particular to a coating device for coloring with a combined color-changing roller. Background technique [0002] Coating equipment is mainly used for the surface coating process of film and paper. Generally, the rolled substrate is coated with a layer of colloid, paint, ink, etc. with specific functions, and then dried and rolled. With the development of modernization, the requirements of industrial production on coating machines are getting higher and higher. The device for coating one color can no longer meet the market demand. At present, many types of coating machines need to have the function of changing colors, but The current color-changing coating device usually requires multiple color-changing rollers to be used alternately for color-changing, which not only increases the cost of the equipment, but also needs to be shut down when changing the rollers, and it is easy to cause color-cha...

With the development of modernization, the requirements of industrial production on coating machines are getting higher and higher. The device for coating one color can no longer meet the market demand. At present, many types of coating machines need to have the function of changing colors, but The current color-changing coating device usually requires multiple color-changing rollers to be used alternately for color-changing, which not only increases the cost of the equipment, but also needs to be shut down when changing the rollers, and it is easy to cause color-changing by changing the rollers Overlapping of colors, resulting in unqualified products

On the other hand, the traditional color coating equipment is prone to uneven distribution of color masterbatch when the raw materials are deposited for a long time and then used, which leads to uneven coating color and greatly affects product quality.
