Application range and working principle of Strip steel slitting machine
The Strip steel slitting machine is a kind of equipment for longitudinal cutting of wide roll material when it is used. Therefore, many of the industries have the word in use, and the strip machine can be used for dividing the paper. Packaging equipment in the mainstream products, packaging market is often visible.
Strip steel slitting machine can also be used in the use of sub-strip leather, cloth, plastic, film and so on the industry, sub-metal coil such as strip strip, stainless steel, copper ... its main for steel processing Plant pod steel market operators, rolling mill manufacturers, electrical industry, cars, stamping parts, and so on.
The essence of the constant tension control in the process of rewinding and winding is the need to know the change in the diameter of the load during operation. As a result of the change of the winding diameter, in order to maintain the load, the machine needs the motor The output torque is changed as the diameter changes.
For the V-series frequency converter, since the torque control can be performed, it is possible to complete the control of the constant tension of the winding. V series inverter provides three analog input port, AUI, AVI, ACI. This three-way analog input port can be defined as a variety of functions, so you can choose any way as a torque reference, another way as a speed limit.
We know that the inverter work at low frequencies, the Strip steel slitting machine AC asynchronous motor characteristics are not good, the activation torque is low and sub-linear, so the whole process of winding up to try to avoid winding motor work in 2HZ below. So the winding motor has a minimum speed limit.
