The scraper system is a mechanical system widely used in many fields, mainly used to scrape off excess material on a specific surface to achieve a more stable and uniform transfer effect and better processing or printing quality.

​

The scraper system mainly consists of three parts: the scraper, the scraped object, and the relative movement.

In a printing press, the main function of the scraper system is to scrape off excess ink on the anilox roller to achieve a more stable and uniform ink transfer, thereby improving the printing effect.

The scraper is generally divided into two parts, namely the sealing scraper and the metering scraper. The function of the sealing scraper is to keep the ink in the chamber to prevent ink leakage, while the metering scraper is responsible for scraping excess ink from the anilox roller, so that the printer can control the ink thickness consistently and present a better printing effect.

In coating machinery, coating scrapers are mainly used to apply a layer of glue, paint or ink with specific functions on materials such as paper, cloth, and leather.

In addition, the scraper system can also be divided into two types: manual and electric, which are suitable for processing requirements of different scales and precisions. At the same time, the material and manufacturing process of the scraper will also affect its performance. For example, metal scrapers are widely used in certain high-precision processing occasions due to their high hardness and wear resistance.

During the operation of the scraper system, some problems may be encountered, such as the scraper movement is not smooth and produces noise, the scraper movement fails and stops at a certain position, and the scraper speed fluctuates, causing gaps or breakpoints in the pattern. These problems may be caused by problems with the ball rod screw mechanism, servo motor failure or controller problems, and need to be checked and repaired accordingly.

The scraper system is widely used in many fields, and its design and type will vary according to the needs of the application field. At the same time, the performance of the scraper system will also be affected by many factors, such as scraper materials, manufacturing processes and operating conditions.
