Slitting machine develops towards digital

With the continuous development of information technology, digital technology is playing an increasingly important role in different fields. The same is true in the packaging industry. After continuous improvement of domestic film slitter technology, there have been significant breakthroughs in speed, width, control and comprehensive performance. Digitalization has also become an important direction for the development of domestic slitter. Many packaging materials are often subjected to cutting-printing (or coating) -composite-cutting and other processes before being used to package items, but the cutting methods in each cutting process are different. Common cutting The methods are: (1) trimming, cutting off the process margins reserved for the previous procedure, mostly used for the processing of composite films and other materials; (2) cutting, cutting wide coils into multiple rolls of narrow specifications (3) Dividing the volume, dividing the large diameter material into several small diameter materials, which is equivalent to rewinding and so on. These methods are sometimes mixed. Regardless of the process used, the material after cutting should meet the corresponding technical indicators: size requirements (refers to the width and length of the cutting material) and quality requirements (flatness of the coil, Surface quality, etc.). Manufacture and purchase of qualified slitting equipment must not only meet these technical indicators, but also must consider the following two factors: operating efficiency, which mainly includes the working speed, stability, and ease of operation of the machine; economic performance, which refers to the The applicable range of materials, the processing limit size, and the price and energy consumption of equipment. With the continuous development of packaging technology and the improvement of packaging grades, the performance requirements of packaged materials on packaging materials have become increasingly prominent. Many materials with special properties have emerged, such as aluminized films with light shielding effects and high surface quality requirements. CPP film with large rate, multi-material composite film with high barrier properties, etc. The continuous application of various new materials has promoted the rapid development of the flexible packaging market. With the growth of market demand and the development of special application fields, the requirements for packaging material slitting are getting higher and higher, and the requirements for slitting equipment are becoming more and more demanding.
