The slitting unit is actually a mechanical, electrical, hydraulic, and integrated equipment that cuts the wide strip material into narrow strips according to the specifications, and is used to cut the strip to the required width specifications. The electrical system of the slitting unit mainly controls each motor, hydraulic system and air system of the unit. The entire electrical system is based on PLC programmable controller, equipped with intuitive human-machine interface and high-precision, high-performance S120 variable frequency speed regulation system and other AC drive control and various detection sensors.

First of all, let's briefly understand the main application situation of the current slitting unit. In the process of using this equipment for longitudinal shearing, it has obvious advantages, including convenient operation, high cutting quality, high material utilization, and stepless speed regulation of the cutting speed. In fact, the equipment is mainly used for unwinding (unwinding). ), lead positioning, slitting and slitting, coiling (rewinding) and other components.

Based on the analysis of the actual production situation, the main production process of the slitting unit can be summarized as: preparing coil → rewinding → unwinding → shovel head, straight head → pinch, leveling → centering (double-row vertical roll) → shear Cutting head and tail (cross-cutting) → centering (double-row vertical roll) → slitting (disc shear) → looper → strip separation and tension control → scrap coiling → coiling → unwinding → collection.

So, what role does the electrical system play in the slitting unit? In fact, the electrical system is used to operate and control the individual equipment of the entire slitting unit, which is a non-standard design electrical control system. The control range is very wide, such as rolling trolley and unloading trolley. The electric control system is composed of PLC automatic control system, AC speed regulation control system, and digital display system. System design and component selection comply with IS9001 and CCC standards.

In addition, during the operation of the slitting unit, the staff can adjust the speed parameters of the electrical system by adjusting the automatic balance adjustment and manual continuous adjustment functions. At the same time, in the slitting unit, its electrical system is also equipped with an automatic detection and automatic display system for the board speed. The AC frequency conversion device equipped with the system is equipped with an input reactor to reduce pollution on the power supply network side.
