Description

Technical Field

[0001] The invention relates to the technical field of coating machines, in particular to a coating machine with an adjustable scraper. Background Art

[0002] Coating machines can coat fabrics. By applying coating agents with different functions on the surface of fabrics, such as waterproofing agents, fire retardants, UV protection agents, softeners, etc., the fabrics can be given various special properties. In the use of coating machines, the coating operation is mostly achieved by the rotation of the anilox roller, and the excess coating and impurities on the anilox roller are scraped off with a scraper to improve the coating effect. However, the existing coating machines have the following problems when used:

[0003] The scrapers of existing coating machines are mostly unidirectional. When scraping, the scraping pressure on the coating surface and the surrounding side surfaces is uneven, which can easily cause fluctuations in coating thickness. At the same time, conventional scrapers are forward scrapers, and foreign matter is easy to get stuck in the scraper, which can easily cause the risk of missing coating. Foreign matter is easy to pass through the scraper and be brought into the product, which can easily cause foreign matter risks, and thus it is inconvenient to improve the stability of coating. Furthermore, for coatings of different thicknesses and different effects, the position and angle of the scraper need to be adjusted. Existing coating machines are not convenient for conveniently adjusting the scraper effect according to the adjustment of the position and angle, and are prone to problems such as uneven scraping and poor impurity treatment, affecting coating efficiency.
