Description

Technical Field

[0001] The utility model relates to the technical field of aluminum plate surface treatment, in particular to surface treatment equipment for cold rolling of aluminum plates and strips. Background Art

[0002] Aluminum plates are widely used in aviation, aerospace, construction, printing, transportation, electronics, chemical industry, food, medicine and other industries. During the rolling process of aluminum plates, due to the large friction coefficient and large pressing force, a large amount of deformation heat and friction heat are generated. Therefore, rolling oil is needed to cool and lubricate the working rollers and aluminum plates and strips during the rolling process. Therefore, there is a lot of cold rolling oil on the aluminum plates and strips, which will affect the later processing of the aluminum plates. The existing surface treatment method for cold rolling of aluminum plates and strips is generally to remove the cold rolling oil by passing the aluminum plates through a vertical scraper through a conveyor belt. The cold rolling oil scraped off the upper surface of the aluminum plates accumulates on the front side of the scraper. The existing surface treatment for cold rolling of aluminum plates and strips cannot adjust the scraper inclination angle according to the different thicknesses of aluminum plates when scraping off the cold rolling oil from the aluminum plates. The scraper has a poor effect in scraping off the cold rolling oil when the aluminum plates are transmitted backwards, and the cold rolling oil accumulated on the front side of the scraper of the aluminum plates cannot be cleaned in time. For this reason, we propose a surface treatment device for cold rolling of aluminum plates and strips. Utility Model Content
