What is the cutting process of the paper cutting machine? Let's understand it together.
        1. Cutting, slitting wide-width coils into multiple rolls with narrow specifications;
        2. Trimming, cutting off the technological margins reserved for the previous process, mostly used for the processing of composite films and other materials;
        3. Separate rolls, divide the large roll diameter material into several rolls of small roll diameter materials, equivalent to rewinding and so on. These methods are sometimes mixed. No matter which process is used, the material after cutting should meet the corresponding technical indicators: size requirements (referring to the width and length of the cutting material, etc.) and quality requirements (flatness of the coil, Surface quality, etc.).
        Manufacturing and purchasing qualified slitting equipment must not only meet these technical indicators, but also must consider the following two factors: operating efficiency, mainly including the working speed, stability and difficulty of machine operation of the equipment; economic performance, refers to the equipment The scope of application of materials, the processing limit size, as well as the price of equipment and energy consumption. With the continuous development of packaging technology and the improvement of packaging grades, the performance requirements of packaging materials on packaging materials have become increasingly prominent, and many materials with special properties have appeared, such as aluminum coating with shading effect and high surface quality requirements. CPP film with high rate, multi-material composite film with high barrier performance, etc. The continuous application of various new materials promotes the rapid development of the flexible packaging market. The growth of market demand and the development of special application fields have made the requirements for packaging materials slitting higher and higher, as well as the requirements for slitting equipment. On the other hand, with the gradual promotion of automated packaging equipment in the packaging industry, such as food packaging, cigarette packaging, etc., these are very picky about the quality of the material after slitting, which gives the slitting machine high grade and high precision Control has brought vast room for development.

        After reading the above, I believe everyone has already understood the slitting process of the paper slitter.
