The cutting machine of the tension system of professional knowledge |
The so-called tension for traction and the aluminum foil according to the standard volume to the volume of the core, to exert a certain tension and foil tension traction, the tensioning force is the tension control of aluminum foil. Tension control refers to the ability to control the lasting aluminum foil on the device when the tension, the control on the machine running speed of any must remain valid, including machine acceleration, deceleration and speed. Even in the emergency case, it also has the ability to ensure the foil does not produce the slightest damage. The cutting machine tension control basic manual tension control, automatic tension control. The manual tension control is in the winding or unwinding process, when the roll diameter changes to a certain stage, adjust by the operator manual power device, so as to achieve the purpose of tension control. Full automatic tension control is composed of a tension sensor for the direct determination of material with the actual tension value, and then the tension data into tension signals back to the tension controller, through the signal and controller predefined tension value contrast, calculates the control signal, automatic control execution unit, the actual tension value and preset tension values are equal, in order to achieve the purpose of stable tension. The equipment volume and tension set size directly affects the rate of finished products, tension is too large, coiling tight, aluminum foil is easy to produce wrinkles I insufficient tension, aluminum foil to on the volume produced shaft serious slip dislocation, even lead to the discharge volume and caused cutting unwinding shaft swing and influence the cutting quality, so cutting machine must have a good tension detection system.
1 Slitter rewinding tension detection system:
It is the tension tension sensor detection of direct detection, and combines with the machinery, detection methods with moving parts. Usually two sensors used, they are installed in the testing guide roller ends on both sides. Strip by testing guide and on both sides of the applied load, displacement or deformation of the tension sensor, to detect the actual tension value and the tension data into tension feedback signal to the tension controller, |
