What kind of doctor blade knifes?

Doctor blade knife is divided into stainless steel blade and polyester plastic blade. Plastic blade are generally used in chamber doctor blade systems and are mostly used as positive blade with sealing action. The thickness of the plastic blade is generally 0.35mm and 0.5mm, and the blade is divided into flat blade and oblique blade. Commonly used steel blade thickness is 0.1mm, 0.15mm, 0.2mm, generally choose 0.15mm, the blade is divided into flat blade, oblique blade Knife edge, thin scraper edge.

What are the structural forms of the blade?

The structure of the doctor balde knife can be divided into two types: forward blade and reverse blade according to the angle of use; according to the assembly form, it can be divided into two types: single doctor blade and chamber doctor blade.

What is the function of the doctor blade knife?

In the inking device with a single doctor blade, the doctor blade is used to scrape off the excess ink on the surface of the ceramic anilox roller, so that a uniform ink layer is left on the surface of the ceramic anilox roller. The two blades in the chamber doctor blade device have different functions, one is reverse type, which scrapes off excess ink on the ceramic anilox roller; the other is forward type, which plays the role of sealing.
