Description

Technical Field

[0001] The utility model relates to the technical field of coating equipment, in particular to a high-efficiency aramid paper coating equipment. Background Art

[0002] In recent years, with the rapid development of industries like electricity and electronics, demand for high-performance materials like aramid paper has continued to grow. Aramid paper offers excellent electrical insulation and high-temperature resistance, making it an ideal choice for electrical insulation. Furthermore, its lightweight, high-strength, and high-temperature stability make it a key material in the aerospace industry. Aramid paper is often not used directly, but rather processed. Some applications involve coating it with a material to enhance its performance, while others involve gluing it and further modifying its shape to meet application requirements. In the process of reprocessing aramid paper, the coating machine plays a very important role. By coating the aramid paper with the aramid paper coating machine, a layer of coating with special functions can be formed on the surface of the aramid paper, thereby enhancing the performance of the aramid paper, such as corrosion resistance and wear resistance, and improving the service life and performance of the material, or facilitating the reprocessing of the aramid paper to meet the use requirements. The anilox roller coating machine is mainly composed of anilox roller, doctor blade, pressure roller, etc. The anilox roller is the core part of the coating machine, and its surface has fine mesh holes for controlling the transfer and distribution of the coating.

[0003] The coating work of the anilox roller coater mainly depends on the micro-concave holes on the anilox roller. During the coating process, the anilox roller is first dipped in the paint, and then turned to the scraper to scrape off the excess paint, leaving only the paint in the mesh holes to be pressed onto the aramid paper by the pressure roller.

[0004] During use, the coating amount of the existing anilox roller coater is difficult to adjust, and the coating amount is directly related to the mesh size and depth of the anilox roller. As a result, once the coating amount needs to be adjusted, anilox rollers of different specifications need to be replaced, which increases the complexity and time cost of the operation. At the same time, only one-side coating can be performed on aramid paper during coating, thereby reducing the production efficiency of aramid paper. In order to solve the above problems, this application proposes a high-efficiency aramid paper coating equipment. Utility Model Content
