TECHNICAL FIELD
[0001] The utility model relates to the field of rolling equipment cleaning technology, especially to a roller dust receiving assembly of a rolling loop. BACKGROUND
[0002] The environment of rolling construction is difficult to achieve dust-free, so the surface of the rolling roller is easy to accumulate oxide skin, dust and other impurities during the rolling process. If these accumulations are not cleaned, they may cause the surface quality of the product to decrease, such as scratches or unevenness. Especially when rolling very thin steel strips, a little dust or particulate matter can scratch the steel sheet and leave obvious marks, causing the entire roll of steel to be downgraded for processing, thereby reducing economic benefits.
[0003] To this end, the current conventional solution is to clean the rolling roller regularly or clean the rolling roller before each rolling. Generally, a scraper is used to scrape off the dust and other impurities. However, regardless of the method or tool used to clean the dust, the dust ultimately needs to be disposed of. Otherwise, the dust will fall on the ground or surrounding equipment, and a little wind or movement will easily cause the dust to be raised, making it more difficult to clean the dust adhering to the surface of the steel strip, affecting the appearance.
[0004] Since the dust cleaned from a rolling roller is not much and is very fine, and the workshop environment does not allow excessive moisture, the cleaned dust is very dry. This causes the moving equipment parts or tools to vibrate or bring a little air disturbance when handling the dust, which easily causes the falling dust to be raised again, causing adverse consequences.
