Carbon fiber roller for film industry
In order to improve work efficiency, improve product quality, and reduce production costs, equipment in the industrial field faces the challenge of high-speed, wide-format operation. These challenges are particularly evident in the film and paper industry. Ordinary steel or aluminum guide rollers, which are affected by mechanical properties such as weight, strength, and rigidity, can no longer meet the conditions of use. In order to maintain competitiveness in the market, it is crucial to develop the guide rollers of film companies towards light weight. In order to meet these requirements, rollers made of carbon fiber composite (CFRP) have proved to be effective and feasible, and have been widely used in many industrial fields.
Because of the lightweight and high-strength performance of carbon fiber material, the guide roller made of carbon fiber composite material has the remarkable characteristics of light weight, high strength, low inertia, high rigidity, high speed, good vibration attenuation and so on.
JSOT can also provide customized carbon fiber rollers for various industrial purposes according to the special needs of customers. Now a series of surface treatment processes have been successfully developed to ensure the excellent performance of the guide rollers while extending the service life of the guide rollers. The surface of the guide roller can be covered with plastic, composite ceramic and metal layer (for example: chromium, stainless steel, copper, aluminum, etc.). At the same time, the surface of the guide roller can be grooved and processed into rhombic and spiral surfaces according to customer requirements.
Carbon fiber composite material roller for aluminum foil industry
During the speed-up process of the slitting machine, the driven guide roller completely relies on the angle formed by the strip and the guide roller, and relies on the front and back tension to tighten the strip. The winding device drives the strip to drive the driven guide roller to rotate. Due to the large weight of the core guide roller, the speed of the guide roller is slowly increased, and the linear speed of the strip cannot be reached in a short period of time. Especially when producing a thin strip, the speed increase is slow due to the small tension Because the linear speed cannot be synchronized, the surface of the strip is seriously scratched, which seriously affects the quality of the product. When the equipment is stopped and the speed is reduced, the linear speed of the guide roller exceeds the linear speed of the strip due to the excessive inertia of the guide roller. Injury, can not meet the quality requirements.
Due to the high strength and light weight of carbon fiber, the original solid steel roller was transformed into a hollow carbon fiber roller. The quality is only between 10-30% of the original steel roller. The larger the roller diameter, the more weight reduction. Due to the light weight, the linear speed of the driven guide roller can be kept the same as the linear speed of the strip, whether it is increasing or decreasing, which ensures the quality requirements of the product. At the same time, due to the excellent elastic modulus of carbon fiber, it has excellent creep resistance and good rigidity, and the vibration is very small under the premise of ensuring processing accuracy, which greatly improves the production speed.
Carbon fiber composite material roller for non-woven industry
In the non-woven equipment, the metal structure of the roller is often used, but as the width of the equipment continues to increase, the deflection of the roller body increases several times, which brings difficulties to the high-speed operation of the equipment. Although it is theoretically possible to reduce the deflection by increasing the diameter of the roller body, the resulting increase in equipment weight brings a series of problems to the processing, installation and use of parts. The application of carbon fiber rolls not only solves the above problems, but also brings the possibility of further innovation of the overall equipment. Carbon fiber composite materials have become an important engineering material due to their unique properties such as high strength, high modulus, and light weight. Their replacement metals and alloys have been used in key parts of nonwoven equipment such as carding machines, netting machines, and winding machines. So as to break the performance limit of traditional structural materials.
Carbon fiber composite material roller for paper industry
In industrial production, in order to increase the productivity of the roll paper (paper, film, aluminum foil, etc.) production process, improve quality, and reduce costs, there are challenges in increasing the width of the roll paper and increasing the line speed. This challenge is particularly significant in the paper industry. In order to remain competitive in the market, it is necessary for paper manufacturers to use light weight, high stiffness, and compact roll rings.
When the carbon fiber roller is used in a paper machine, the roller has two important technical characteristics: it can rotate stably under ultra-high speed and has a long service life. One important point is the manufacturing technology of the roller. In order to realize the stable rotation of the roller under ultra-high speed, the roller must have a high dynamic balance, and the other is the surface treatment technology of the roller. At the same time, the surface of the paper moving at high speed can be rough, so the key is that the surface of the drum should have high wear resistance. The surface treatment process can make the surface of the carbon fiber roller have high wear resistance. In order to exhaust and increase the wear resistance of the roller surface, the surface of the carbon fiber roller can be grooved and the surface is compounded with tungsten carbide, metal, ceramic, anti-sticking material, etc.
Carbon fiber composite material roller for packaging industry
In actual production, the roller usually bears a large pressing force, and produces a certain separation force relative to the product, so that the roller looks like a cylindrical beam supported on the bearings at both ends, so it cannot be calculated by the general beam bending theory formula For its deformation, use the formula of the total value of deflection to find its maximum deformation. The total deflection of the middle of the roller is far greater than the allowable tolerance of the product, so it must be compensated, otherwise the accuracy of the product will not be met, which will cause inconvenience to the processing of the roller.
The carbon fiber roller produced by JSOT has sufficient rigidity to ensure that the bending deformation does not exceed the allowable value under heavy load. The roller shell is a carbon fiber tube. The carbon fiber tube has a variety of molding methods, including winding molding, tube winding, and pultrusion. Taking into account the characteristics of the roller, the winding molding method is used.
Carbon fiber composite material roller for printing industry
In printing machinery, many types of guide rollers can be replaced by custom-designed carbon fiber rollers. The anilox roller is one of the most important parts in flexo printing machines. The deflection of the roller has a great influence on the uniformity of the ink layer. The anilox roller made of carbon fiber material has very low rotational inertia, high rigidity, light weight and low kinetic energy. After using this advanced material, the overall performance of the equipment is significantly improved, the printing speed and printing quality are improved, and a uniform ink film can be obtained on the printing material.
Carbon fiber composite material roller for energy storage flywheel
Carbon fiber is a fibrous carbon material, which has the advantages of high strength, high modulus, low density, low expansion, high temperature resistance, fatigue resistance, etc., and has good functional designability. The structure of carbon fiber composite material flywheel mainly includes solid structure, hollow structure, nearly hollow structure and so on. The mass of the hollow structure flywheel is mainly distributed on the rim, so that the energy stored by the flywheel is maximized, and the mass of the flywheel is reduced, which increases the energy storage density. Carbon fiber products have various molding methods, including winding molding, compression molding, resin transfer molding, and hot-pressing can molding. Taking into account the characteristics of the flywheel, the winding molding method is used.
