Why choose carbon fiber roller

Why choose carbon fiber roller：

New energy batteries, paper, film, aluminum foil and other industrial fields are facing the problem of increased web width and line speed. In order to further improve production efficiency, improve product quality, and reduce production costs, carbon fiber rollers with light weight and strong rigidity are used. Become one of the effective solutions.

First of all, when the paper slitter / rewinder is running at ultra-high speed, the length of the single roll surface is directly related to the critical speed of the roll: the critical speed of the roll is inversely proportional to the square of the roll length, when the length of the roll doubles At that time, the critical speed will become a quarter of the original. Now, the width of the roll paper is getting larger and larger, and the increase in the width has gradually become a development trend of similar machinery. To reach a higher critical speed when the length of the roller is longer, the weight of the roller must be Keep it as low as possible, and the elastic modulus of the roller shell must reach a certain standard. Carbon fiber rollers made of carbon fiber composite materials with an elastic modulus of 240 GPa can meet the above requirements.

Secondly, when the paper is running on the surface of the carbon fiber roller, their surfaces have sufficient frictional traction. When the speed changes, the force becomes unstable due to the entry of air, which may cause the paper to detach. Roll surface. In order to avoid the acceleration of the roller caused by the sliding of the paper during high-speed conversion, the wear resistance of the roller surface must be increased. However, the high hardness and rough surface can cause paper scratches and paper dust problems. This problem is particularly obvious on undriven idlers. The ideal way to solve this slippage is to use a low-inertia roller. Because the carbon fiber roller has extremely light weight and very small inertia, it can effectively reduce the tension of the web, better match high-speed movements and adapt to rapid changes in acceleration and deceleration.
