Viscose refining machine

The utility model provides a viscose fiber refiner, which relates to the technical field of viscose fiber production equipment, and is characterized in that sight glass is arranged on a refiner door, so that related workers can observe the condition inside the refiner through the sight glass, and a sight glass scraper is arranged on one side, close to the inside of the refiner, of the sight glass; the rotating component is used for driving the sight glass scraping plate to rotate, so that the sight glass scraping plate can scrape the sight glass, water on the sight glass can be completely scraped without opening a door of the refiner, the conditions of water spraying, cotton laying and the like in the refiner can be more intuitively and clearly observed, and the problem that in the prior art, when the conditions in the refiner need to be observed, the working efficiency is high is solved. The door of the refiner needs to be opened for observation, and the door opening observation can cause harm to the environ
