Carbon Fiber Floating Roller for Slitting

Introduction of Carbon Fiber Floating Roller for Slitting:

Carbon Fiber Floating Roller for Slitting is a specialized roller used in slitting processes. It is designed to provide precise and efficient slitting of various materials, such as films, papers, and foils. The floating feature allows the roller to adapt to variations in material thickness, ensuring consistent and accurate slitting results.

Controlling Principles of Carbon Fiber Floating Roller :

(1) Single floating roller tension control system

The single floating roller tension control system is mainly composed of floating roller 3 low friction cylinder 4 potentiometer 5 etc. When the upper chamber of the cylinder is supplied with compressed air, the tension acting on the film is the sum of the vertical component of gravity of the roller and the vertical force of the cylinder. Because the floating roller swing angle is small. The vertical component force is basically unchanged during the swing process, so the tension of the film can be adjusted by directly changing the pressure of the cylinder. The tension has nothing to do with the diameter of the film roll. During the winding process. When the tension changes, the corresponding swing potentiometer of the floating roller indirectly detects the tension change. After adjusting P and D, the winding speed is controlled to keep the film tension constant.In addition to the above-mentioned real-time tension control when applied to the center winding process, there is also an increase in the diameter of the film roll.

The process in which the angular velocity gradually decreases while the linear speed of the film roll remains unchanged. At the beginning, the pulling force of the web on the floating roller and the gravity of the roller itself. The thrust of the cylinder is balanced and the floating roller is in the middle balance position. As the diameter of the film roll 6 increases. The floating roller 3 swings upward, driving the potentiometer 5 to rotate, causing the feedback signal to deviate from the original balance point voltage value. This signal is compared with the given voltage signal to obtain the deviation value. After integral calculation, the motor speed is adjusted so that the motor speed decreases and the web tension returns to the given value. The floating roller returns to its original equilibrium position. During the entire winding process, as the diameter of the film roll increases, the motor speed is continuously adjusted to keep the film knife constant. Under normal circumstances, the change range of film roll diameter is generally 5-8 times. If the servo drive mode is used, the speed adjustment range can reach about 10 times.

2) Double floating roller control method

During high-speed operation or low-tension winding process. The requirements for tension are more prominent. Although single dancer roller control can absorb some tension fluctuations, the change in inertia caused by the weight of the dancer roller during movement will also cause changes in film tension. Compared with a single floating roller, the double floating roller method has a roller swing range of half that of a single floating roller. At the same time, the weight of each floating roller can be made lighter. The change in tension caused by inertia is also small. If the weight of each floating roller is 1/2 of the original, the tension change can be 1/4 of the original, making the knife opening more stable during the film winding process.
