As a versatile raw material in many aspects like household cooking, food packaging, battery, the sold aluminum foil sizes are usually large, that is, aluminum foil jumbo roll. It is usually of 12000 meter. Before reaching the final customer like household aluminum foil customer, it needs to be further processed.
Aluminum foil needs to be slit on a slitting machine. The aluminum foil jumbo roll is cut into the required specifications. Slitting on a slitting machine is a process of unwinding and rewinding. This process includes two parts: the machine's operating speed control and tension control.
The so-called tension means that in order to pull the aluminum foil and roll it onto the core according to the standard, a certain stretching and tensioning force must be applied to the aluminum foil, in which the control force of the tensioned aluminum foil is the tension.
Tension control refers to the ability to well control the tension of aluminum foil when it is transported on the equipment. This control must be effective at any operating speed of the machine, including the acceleration, deceleration and uniform speed of the machine. Even in the event of an emergency stop, it has the ability to ensure that the aluminum foil is not damaged at all.
Slitting machine tension control is basically divided into manual tension control and automatic tension control. Manual tension control means that during the winding or unwinding process, when the winding diameter changes to a certain stage, the operator adjusts the manual power device to achieve the purpose of controlling the tension.
Fully automatic tension control uses a tension sensor to directly measure the actual tension value of the material belt, and then converts the tension data into a tension signal and feeds it back to the tension controller. By comparing this signal with the tension value preset by the controller, the control signal is calculated. The automatic control execution unit makes the actual tension value equal to the preset tension value to achieve the purpose of stable tension.
