Aluminum foil paper, cash register paper after printing coating needs to be on the cutting machine cutting after printing, the large volume of semi-finished cut to the desired size, cut on the cutting machine operation is a semi-finished roll with rolling release the process, which involves the operation of the machine speed control and tension control two parts.
The so-called tension to pull the standard aluminum foil and roll onto a core, must exert a certain tension to the foil and the tension of traction, which is tensioned foil tension control. Tension control refers to the ability to control persistent tension on the foil conveying device, which controls the speed of the machine must be maintained in any effective, including machine acceleration, deceleration and constant speed. Even in an emergency stop situation, it also has the ability to ensure that the aluminum foil does not produce the slightest damage. Slitting Tension Control basic manual tension control, automatic tension control. Manual tension control is in the process of winding or unwinding, when the roll diameter changes to a certain stage, by the operator manually adjusting the power supply device, so as to achieve the purpose of controlling the tension. Automatic tension control is the actual measurement value of the strip tension directly from the tension sensor, and then converts the data into a tension signal back tension of the tension controllers, tension by comparison of this signal with a preset control, the control signal is calculated, automatic control execution means, so that the actual value of the tension with a preset tension value are equal, in order to achieve a stable tone. Size of the device and the winding unwinding tension settings directly affect the product yield, the tension is too large, winding tight, aluminum foil is easy to produce wrinkles I insufficient tension foil prone to serious dislocation slip axle on the volume, as well as causing unable unloading and cause the discharge produced when cutting reel to swing, affecting the quality of the cutting, so cutting machine must have good tension detection system.
1. Slitting rewinding tension detection system:
Tension sensors detect that it is the direct detection of tension, and mechanical work closely together, with a detection method of moving parts. Usually paired with two sensors, they are mounted on the end of the shaft is detected on both sides of the guide rollers. Tape guide rollers by detecting a load applied to both sides, the tension sensor sensing element is displaced or deformed, and the actual tension detected value, and converts this data into a tension to the tension of the tension controller a feedback signal.
2. Slitting unwinding and rewinding tension and tension attenuation compensation:
It is generally believed that when aluminum foil unwinding and rewinding to maintain constant tension, conducive to performance quality finished aluminum foil, it is not. The best way is with the increase of the roll diameter or weight, according to certain rules to increase aluminum foil tension, the tension and the diameter of the smaller weight value also will be attenuated. Since the slitting operation with automatic tension control and manual tension control. Manual tension control requires the operator based on the weight of the masterbatch roll diameter size to constantly adjust.
