Development of automatic cutting related technologies

From:Xionghua  Time:2017-06-08

With the development of information technology, digital technology is playing a more and more important role in different fields. The same is true in the packaging industry. With the continuous progress of domestic film slitting machine, there are obvious breakthroughs in speed, width, control and comprehensive performance, and digitization has become an important direction of the development of domestic slitter. Many packaging materials before being used for packing goods, often after cutting - printing (or coating) - composite - cutting multiple processes, but each cutting cutting process is not the same, the common cutting methods are: (1) the cutting edge, cut on the procedures of reservation process material, used for processing of composite membrane materials; (2) cutting, the wide membrane into multiple narrow size materials; (3) volume, the roll diameter material into several small roll diameter equivalent material, rewinder etc.. These sometimes mixed use, regardless of the kind of process, after cutting the material should meet appropriate specifications: size requirements (the width and length dimensions of cutting materials etc.) and quality requirements (flatness, roll surface quality etc.). Manufacturing and purchasing qualified cutting equipment should not only meet the technical indicators, but also must consider the following two factors: efficiency, including equipment working speed, stability and machine operation difficulty; economic performance, refers to the scope of material processing equipment, limit the size and price of equipment, energy consumption with the continuous development of packaging, improve packaging grades, packaging materials for packaging materials by performance requirements have become increasingly prominent, and there have been many special properties of materials, such as aluminum film with shading effect and surface quality is high, the elongation of CPP films is larger, with high barrier performance of multiple materials such as composite films. The continuous application of various new materials to promote the rapid development of flexible packaging market. With the increase of the market demand and the development of special application fields, the requirement for the cutting of the packing material is higher and higher, and the requirements of the slitting equipment are becoming more and more severe. On the other hand, with the gradual promotion of automated packaging equipment in the packaging industry, such as food packaging, cigarette packaging, quality of the slitting after the material very picky, this gave the cutting machine to high-grade, high precision control has brought a broad development space.
