Digital control of the hottest Slitter

  • Detail

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 progress, the technology of domestic film slitter has made significant breakthroughs in speed, width, control and comprehensive performance. Digitalization has also become an important direction for the development of domestic film slitter

prodigy II cut the master roll with a film width of more than 1000mm into 20mm films at least. The cutting edge is neat under high-speed operation, and the cutting effect is good

before being used for packaging, many packaging materials often go through many processes, such as slitting printing (or coating), compounding and slitting, but the cutting methods in each slitting process are different. The common slitting methods are: (1) cutting edge, cutting off the process edge reserved in the previous process, which is mostly used for the processing of composite films and other materials; (2) Cut, cut the wide coil into multiple rolls of narrow size material 1 design idea; (3) Sub roll, which divides the large roll diameter material into several rolls of small roll diameter material, which is equivalent to rewinding, etc. These methods are sometimes used in combination. No matter which process is adopted, the material after slitting should meet the corresponding technical indicators: size requirements (refers to the width and length of the slitting material, etc.) and quality requirements (flatness of the coil, surface quality, etc.)

manufacturing and purchasing qualified slitting equipment should not only meet these technical indicators, but also consider the following two factors: operating efficiency, mainly including the working speed and stability of the equipment and the difficulty of machine operation; Economic performance refers to the scope of application of equipment to materials, the processing limit size, as well as the price and energy consumption of equipment

with the continuous development of packaging technology and the improvement of packaging grade, the performance requirements of packaged items on packaging materials are becoming increasingly prominent, and there are many materials with special properties, such as aluminum plating film with shading effect and high surface quality requirements, CPP film with large elongation, 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. With the growth of market demand and the development of special application fields, the requirements for the slitting of packaging materials are becoming higher and higher, and the requirements for the slitting equipment are becoming more and more stringent. Additional accessories can be used for tightening and tortuous experiments. On the other hand, with the gradual promotion of automatic packaging equipment in the packaging industry, such as food packaging, cigarette packaging, etc., these automatic packaging machines are very picky about the quality requirements of the materials after slitting, which brings a broad development space for the slitting machine to high-grade and high-precision control

in the past, the high-precision and high-speed slitter used by domestic enterprises was mainly monopolized by a few foreign manufacturers. As for the development of domestic slitting machine, there is such an image metaphor in the industry: in the early stage, the side wheel of the automatic car received a huge load. The structure of the slitting machine is simple, the speed is about 100m/min, and the mechanical friction mode of the winding tension is manual control, which people call it "machine"; Later, after some transformation, the winding is controlled by means of clutch, and the traction and winding are controlled by a single motor. The speed is less than 200m/min, which is called "Simulator"; Since then, the new full-automatic high-speed Slitter, using digital automatic control, has a speed of more than 300m/min, just like the "digital machine" in the field of modern communication that meets the requirements of deep drawing parts manufacturing standards

with the improvement of the technical capacity of domestic enterprises, different manufacturers have launched digital controlled high-speed slitting machines. The following introduces the high-speed digital control slitting machines produced by several domestic manufacturers to get a glimpse of the latest progress of domestic slitting technology

new concept of intelligent slitting

Hangzhou Dahua Industrial Control Technology Co., Ltd. developed a product tailored for mainstream users in the flexible packaging industry at the beginning of this year - little prodigy II slitting machine. The little prodigy II flexible packaging Slitter series has absorbed many advantages of Dahua Slitter in the past. It adopts the central winding mode and the latest digital control and drive technology, with a stable working speed of 300~400 meters/minute, a winding diameter of 800 mm, a winding diameter of 500 mm, and a minimum winding width of 30 mm. In addition, the film connecting table, waste edge treatment system and cutter conversion system specially designed for this machine have originality, and more options can meet the specific requirements of more customers. The man-machine dialogue system with digital control makes the operation more convenient. This Slitter can Slitter PE, PP, PVC and PET films, paper and composite films. The whole design takes high speed, high efficiency, high precision and high reliability as the basic requirements, so that customers can truly experience the excellent performance of high-quality and cost-effective Slitter with moderate price

through continuous innovation, Dahua Industrial control has successively developed a series of digital slitting machines. The slitting machines of XIAOBAWANG, oushen, xiaowutong II and other series are being used by more and more users. On the basis of digital slitting machine technology, Dahua Industrial control has recently introduced a new concept - intelligent high-speed slitting machine, a new generation of slitting machine that is more perfect, more practical and more powerful

intelligent high-speed slitting machine continues all the advantages of Dahua slitting machine in the past. On the basis of high speed, high efficiency and high reliability, it adds significant functions of slitting experts, including: process expert function, operation expert function and after-sales service expert function. Intelligent slitting machine solves the problem of complex operation of high-end slitting machine. The introduction of intelligence makes the performance of this new generation of slitting machine tend to be perfect

process expert function the film industry experience of Dahua Industrial Control R & D personnel enables this function to be realized. Through optimized parameters, the cutting can be achieved with one key. In short, just like a point and shoot camera, people without professional photography skills can take clear photos. It makes the operation very easy to use, so that people who are not familiar with the material can also finish the slitting well and cut out the film with good quality. At the same time, the mode of setting parameters by users is reserved

the function of operation expert endows the machine with intelligence. Experienced operators can set parameters to meet the special cutting needs of some enterprises, and realize the interaction of man-machine interface. The operators can effectively communicate with the cutting machine, which greatly reduces errors, essentially reduces the incidence of errors, and makes the operation orderly, just like an expert around

after sales service function Dahua Industrial control realizes this function through a series of measures, accurately displays machine faults, facilitates maintenance and repair, and makes the machine operate efficiently. Intelligent high-speed slitting machine has the characteristics of convenient operation, high slitting quality and improved efficiency. Dahua Industrial control has completed the above technical upgrading and provided customers with the upgrading service of Dahua Slitter in the past
