Description

Technical Field

[0001] The utility model relates to the technical field of casting machines, in particular to a scraper structure for a casting machine. Background Technique

[0002] The casting machine is a key device in the production process of sheet materials such as plastic films, papers, and metal foils. The scraper structure is a crucial component in the casting machine, which is used to directly contact and level the molten material, directly related to the product quality and production efficiency. The existing scrapers cannot be adjusted according to the thickness requirements of the casting film, reducing the applicable range of the scrapers.

[0003] The Chinese patent discloses a scraper for a casting film machine for production (authorization publication number CN212736744U). This patented technology can accurately adjust the up and down position of the scraper by rotating the adjusting screw and according to the scale bar, and can be used for processing casting films of different thicknesses. While ensuring the processing quality of the casting film, it improves the applicable range of the scraper, and the structure design is reasonable and the operation is convenient.

[0004] However, it has certain drawbacks: it adjusts the height of the scraper by rotating the adjusting screw to make it rise and fall. In actual production, the adjusting screw will rotate unnecessarily due to vibration, mechanical vibration, or accidental touch during operation, resulting in a change in the height of the scraper, thereby affecting the product quality.
