Description

Technical Field

[0001] The utility model relates to a coating machine, in particular to a medical tape coating machine. Background Art

[0002] Analyzing the development in recent years, the future development of coating technology may present the following three important characteristics: blade coating will remain the main coating method for some time in the future, and is developing in the direction of high speed and high solid content; metered sizing press coating is widely accepted and developing rapidly; new coating methods such as spray coating and curtain coating have received widespread attention, indicating a bright development prospect; however, the above development cannot be smooth sailing and must face many technical challenges. High-solid content blade coating will produce operational problems such as blade marks, high blade pressure, coating precipitation on the blade (commonly known as flipping) and fast blade wear; metered sizing press coating must face many difficulties brought about by high-speed, high solid content and high coating amount coating.
