[0002] A coating scraper is a long strip with a certain curvature on the blade. It is used in coating machines to apply a layer of glue, paint or ink with specific functions on materials such as paper, cloth, leather, aluminum foil, and plastic film. It is a special mechanical blade.

[0003] When a conventional coating scraper is used to scrape the paint, the paint needs to be placed on a support plate first, and a large amount of paint is attached to the cloth after the moving cloth passes through the paint on the support plate, and then the paint is scraped off with the scraper. Therefore, this method has the following defects: the paint placed on the support plate will be exposed to the outside world and contact with the outside air for a long time, causing the paint to adhere to dust and affect the quality after coating. To this end, we propose a coating machine scraper. Utility Model Content
