After printing and coating, the aluminum foil needs to be cut after printing on the slitting machine, and the large roll of semi-finished products must be cut into the required specifications. However, running the slit semi-finished product on the slitting machine is a process of unwinding and winding, which includes two parts: the machine's operating speed control and tension control.
How to control the tension of the slitter? First of all, choose an advanced model, and pay attention to which winding and unwinding tension detection and control system is used in the equipment during operation, understand its characteristics, and formulate a reasonable tension for the aluminum foil material used and the tension during the winding and unwinding process Attenuation and compensation to achieve soft start and soft stop of equipment tension to prevent quality problems.
During the slitting operation of the slitting machine, the operator should always pay attention to the change of the aluminum foil winding tension, because it is affected by the material quality, weight, thickness uniformity, and slitting speed changes. When setting the winding tension It must be compatible with these characteristics of aluminum foil.
At the same time, in order to ensure that the tension control of the slitting machine is accurate during rewinding and unwinding, dynamic balance treatment should be carried out when the tension detection roller of the rewinding and unwinding mechanism should be higher than the maximum speed per hour, and the surface should have enough space during use. The angle of wrapping can provide accurate running tension and ensure the stability of product quality.
