Description

Technical Field

[0001] The utility model relates to the field of coating machines, in particular to a scraper adjustment structure for coating machines. Background Art

[0002] A coater is a device that coats a roll of substrate with a layer of adhesive, paint, or ink, drying it, cutting it into sheets or rewinding it. It is primarily used for coating the surfaces of films, paper, cloth, textiles, and electronic products to modify the substrate's properties, appearance, or functionality. The coating machine's blade adjustment mechanism is a crucial component, regulating the blade's distance to ensure accuracy and quality during the coating process.

[0003] The scraper adjustment structure of the existing coating machine can only adjust the distance of the scraper, and its function is relatively simple. The scraper is exposed to the outside, which will cause unnecessary friction and collision, increase surface wear, reduce service life, and increase safety hazards. In addition, the scraper will accumulate a lot of paint during the coating process. The accumulated paint will cause the paint to not be evenly distributed on the substrate during coating, and will also cause damage to the coating machine, increase the incidence of equipment failure, and increase maintenance costs.

[0004] Therefore, it is necessary to propose a new scraper adjustment structure for a coating machine to solve the above problems. Utility Model Content
