With the increasingly fierce market competition, the demand for high efficiency and environmental protection in the industrial field has become increasingly clear. In the manufacture of roll products such as paper, film and aluminum foil, while meeting the requirements of large width and high line speed, it is also necessary to reduce energy consumption and production costs as much as possible. As an important mechanical part, the performance level of rollers directly determines the production efficiency ratio. Carbon fiber rollers have the advantages of light weight, small inertia, low deflection angle, and high natural frequency, which can bring more diversified advantages to different types of industrial machinery.
Modern and high-efficiency production equipment puts forward high requirements on the roll body material: the roll body material must have sufficient strength to withstand high-load operation; the roll body material must be as light as possible to effectively reduce the long-term production energy consumption; the corrosion resistance and fatigue resistance of the roller body material should be good, so as to reduce the maintenance and application cost of the roller body as a whole; the dynamic balance of the roller body must be good enough to maintain stable mechanical rotation at ultra-high speed; the surface of the roller body It must have good wear resistance in order to meet high-efficiency and high-volume production requirements and so on.
For large-width equipment, when the ratio of the length to the diameter of the roll is too large, and the rotation speed is high, it is very difficult for the roll body to maintain sufficient balance during operation, especially for metal rolls such as steel. Rollers are more prone to distortion and deformation during high-speed operation, and the faster the machine runs, the greater the amount of deformation, and the increase in energy consumption. Moreover, if the roller body vibrates too much, materials such as paper will wrinkle. When the material swings too much on the roller body, it will also put pressure on the cutter and other procedures. Using carbon fiber with light weight and high elastic modulus instead of metal materials to make the roller shell can not only help the equipment better realize high-speed movement, but also help accelerate or decelerate the movement quickly, because the lightweight roller body material can be effective Reduce the moment of inertia.
Carbon fiber rollers not only have unique application advantages in the production of web products, they can also play a special role in printing and other industries. The hardness of the carbon fiber roller is twice that of the steel roller, but the actual offset is only 10% of that of the steel roller. Only a small offset can ensure high-quality printing results. Therefore, the carbon fiber roller can effectively improve the printing level of the machine.
At present, Wuxi Coreco can customize various types of carbon fiber rollers, and the products can be used in different industries such as textiles, papermaking, printing, thin films, and lithium batteries. Because of rich experience and stable craftsmanship. The finished carbon fiber roller has high precision and good dynamic balance performance, giving full play to the advantages of high strength and light weight of carbon fiber. It opens up a new direction for the development of industrial manufacturing in the direction of "high efficiency and low energy consumption".
