Online roller surface cleaning device

Abstract

The invention relates to an online roller surface cleaning device. A scraper structure controlled through mechanical transmission is designed on the basis of the rotating work of a to-be-cleaned roller (1), a movable plate (3) is rotated by erecting a matched rotating shaft (5) on the basis of a base (2), and under the control of inflation and deflation of an air bag (7), the movable plate (3) drives an arranged scraper (4) to mechanically rotate, the edge of an upper blade of the scraper (4) makes contact with or is separated from the surface of the to-be-cleaned roller (1), the surface of the to-be-cleaned roller (1) is automatically cleaned in combination with rotation of the to-be-cleaned roller (1) itself, one-key operation is achieved in the whole implementation process, cleaning operation can be stopped at any time, the whole design structure has a stable working process, and the working efficiency of cleaning work is effectively improved.

Description

technical field [0001] The invention relates to an online roller surface cleaning device, which belongs to the technical field of roller surface cleaning. Background technique [0002] In the cold rolling production process, the number of surface defects of finished products is very high, accounting for more than 100% of the total number of judgments. The main defects are gravure, roll marks, scratches, etc. The main factor causing such defects is the contact with the strip steel There are impurities and foreign matters on the surface of the roll, which are transferred to the surface of the strip to cause such defects. In order to remove impurities and foreign matters on the surface of the roll, the existing technology installs a scraper on the roll surface. The existing scraper in the cold rolling plant is made of carbon steel. It is easy to cause damage to the roller, and the design of the system device is old, the knife body has uneven pressure on the roller and the effec...

[0002] In the cold rolling production process, the number of surface defects of finished products is very high, accounting for more than 100% of the total number of judgments.

In order to remove impurities and foreign matters on the surface of the roll, the existing technology installs a scraper on the roll surface. The existing scraper in the cold rolling plant is made of carbon steel. It is easy to cause damage to the roller, and the design of the system device is old, the effect of scraping slag is not ideal due to the uneven pressure of the knife body on the roller, and the scraper action is manual operation, which increases labor intensity and is ineffective in dealing with sudden problems.
