Description

Technical Field

[0001] The utility model relates to the technical field of steel strip cold rolling oil scraping mechanisms, in particular to an oil scraping mechanism for steel strip cold rolling processing. Background Art

[0002] Cold rolling of strip steel is a production process when processing steel. It uses the cold extrusion method. There will be a large amount of lubricating oil on the steel strip coming out of the cold rolling mill. In order to save costs and protect the environment, the lubricating oil on the surface of the steel strip needs to be recovered and reused, and an oil scraping mechanism is needed to scrape it off.

[0003] According to the description of an oil scraping mechanism for cold rolling of steel strip disclosed on the patent website (authorization announcement number: CN218798210U), "The utility model discloses an oil scraping mechanism for cold rolling of steel strip, including a chassis, a spring and an infrared sensor. A controller is provided on one side wall of the chassis, a discharge port is provided on the other side wall of the chassis, and a feed port is provided on the side wall of the chassis opposite to the discharge port. The beneficial effect is that the utility model can freely adjust the oil scraping distance through the electric telescopic rod, spring, mounting frame, scraper and waste bin, and the scraper can float freely up and down, which is suitable for scraping oil from steel strips of different thicknesses, thereby improving the convenience of the oil scraping mechanism when in use. The infrared sensor, electric hydraulic rod, lower pressure roller, electric push rod and upper pressure roller can be provided to freely adjust the tightness of the steel strip, so that the oil stains on the steel strip can be fully scraped off, thereby improving the oil scraping quality of the oil scraping mechanism."

[0004] In view of the above description, the applicant believes that there are the following problems:

Therefore, it is necessary to improve an oil scraping mechanism for cold rolling of steel strips to solve the above problems. Utility Model Content
