The slitting unit is actually a machine, electrical, hydraulic and integrated equipment which is used to cut wide strip steel into narrow strips according to the specification requirements. The electrical system of the sliver unit mainly controls the motors, hydraulic system and pneumatic system of the unit. The whole electrical system with PLC programmable controller as the core, with intuitive man-machine interface and high precision, high performance S120 frequency conversion speed regulation system and other ac drive control and various detection sensors.
First of all, we have a brief understanding of the main applications of the slitting machine. In the process of using the equipment for longitudinal shear, it has obvious advantages, including convenient operation, high cutting quality, high material utilization rate, cutting speed stepless speed and other advantages, the equipment is actually mainly by uncoiling (uncoiling), lead positioning, slitting longitudinal shear, coiling (winding) and other components.
Combining with the actual production situation analysis, the article points the unit of the main production process can be summarized as: prepare the volume - - open book - shovel head, head straight to pinch, leveling, the vertical roll (double) in the head and tail (cross) and shear - the vertical roll (double) in the - slitting cutting (disc) - loop - steel band separation and tension control to the waste edge coiling, coiling to discharge volume, collection.
So, in the sliver unit, what kind of role does the electrical system play? In fact, the electrical system is used to operate and control the whole sub-unit of each single equipment, is a non-standard design electrical control system. Control range is very wide, such as winding car and unloading car. The electronic control system is composed of PLC automatic control system, ac speed control system and digital display system. The system design and components are in accordance with IS9001 and CCC standards.
In addition, in the operation process of the sliver unit, the staff can adjust the speed parameters in the electrical system by adjusting the automatic balance adjustment, manual continuous adjustable function. At the same time, the electrical system is equipped with automatic speed detection and automatic display system. The ac frequency conversion device equipped with the system is equipped with an input reactor to reduce the pollution on the side of the power supply network.
