A slitting knife is an industrial cutting tool specifically used to cut large sheet materials into narrow strips. Its working principle involves the precision cutting of materials by a high-speed rotating blade and is commonly used for processing materials such as film, paper, metal strips, and plastic film. The cutting method of a slitting knife generally uses rotary cutting, which offers higher precision and efficiency compared to traditional straight knife cutting methods. The working principle of a slitting knife mainly relies on the relative motion between the blade and the material. As the material passes through the blade, the rotating blade quickly makes contact with it, generating strong shearing forces that precisely cut the material to the desired width. To ensure cutting accuracy, slitting knives are usually equipped with high-precision adjustment systems, allowing the blade spacing and angle to be adjusted according to different cutting requirements. In practical applications, slitting knives are widely used in printing, packaging, paper processing, metal strip slitting, and other fields. For example, in paper processing, a slitting knife can cut large sheets of paper into rolls of different widths to meet various production needs.
