The application forms of carbon fiber composite materials in the industrial field are gradually becoming diversified, and carbon fiber composite material rolls are one of the application forms with great development potential. Recently, carbon fiber rollers have been used in various industrial machinery such as papermaking machinery, printing machinery, textile machinery, and film machinery, but in general, the application advantages of carbon fiber rollers are very high, and compared with traditional metal rollers, they show weight Lightweight, low inertia, low deflection angle, high natural vibration frequency, etc., then let's learn about the application of carbon fiber rollers in industrial machinery!
Raising roller for textile machinery:
The raising machine is a spinning machine that pulls the end of the fiber out of the yarn and evenly covers the surface of the fabric with fluff. The raising roller is an important roll body in the raising machine, and the traditional raising roller is made of steel. In order to meet the high speed requirements of the raising machine, the steel raising roller needs sufficient wall thickness to ensure sufficient rigidity, but this rigidity sacrifices the increase in self-weight and energy consumption. Nevertheless, the fatigue resistance of steel napping rollers is not enough. Due to the certain ductility of metal, the longer the steel roll shaft is, the easier it is to distort and deform during high-speed operation, which affects the quality and effect of fluffing. Therefore, in order to avoid obvious deformation of the steel raising roller, the length is mostly limited, usually no more than 2 meters.
The roller part of the raising roller is manufactured by rolling method. Among them, the layup design of carbon fiber prepreg is very flexible, and the layup method of prepreg can be reasonably designed according to the strength requirements of the raising roller in all directions, and the layup design can be carried out according to the size and performance requirements of the product, which is convenient for controlling the layup thickness, extending the roll surface.
The napping roller made of carbon fiber composite material is 70%-80% lighter than the traditional steel roller. It has low vibration, low noise, high strength and good straightness during operation. The critical speed is greatly increased, and the time required for start-up is reduced. From the perspective of long-term application, carbon fiber composite materials have high rigidity and better fatigue resistance. equipment maintenance costs.
Non-woven equipment cross pad moving roller:
Special equipment for non-woven fabrics includes carding machines, netting machines, coilers, etc. With more and more applications, this type of non-manufacturing equipment is developing in the direction of increasing width, improving process speed and equipment reliability.
The roller structure in non-woven equipment mostly uses metal materials, but as the width of the equipment increases, the deflection deformation of the roller body increases several times, which hinders the high-speed operation of the equipment. In theory, increasing the diameter of the roll body can reduce deflection, but in practice it inevitably increases the weight of the device, making installation and operation difficult for the user. The application of carbon fiber composite material roller can solve the above problems well, and also help to improve the overall performance of the equipment. The cross pad machine is a special machine in the non-woven equipment. It overlaps the thin web output by the carding machine with the cross pad to obtain a thick web. It is not limited by the working width of the carding machine and can reduce or increase the width of the mat. To put it simply, the process of laying nets is completed by several rollers working horizontally to drive the curtains laying nets back and forth. In this process, these rollers have rotary motion and horizontal reciprocating motion. In order to increase the speed of laying, it is necessary to increase the rotation speed and reciprocating speed of the drum. However, if the moment of inertia and the overall inertia of the rollers increase, it will be difficult to control the deceleration and acceleration process of the net car when turning at both ends, and the two sides of the net will be thicker than the middle.
In this case, the roller used in the center of the screen is fully upgraded. After the replacement, the weight of the carbon fiber roller is reduced by 80%, the moment of inertia and overall inertia are significantly reduced, and the screen speed is doubled. At the same time, the carbon fiber roller body has the characteristics of high strength and high shape.
