Introduction to Decoiler cum straightener

　　Decoiler cum straightener, also known as slitting line, slitting machine, Decoiler cum straightener, is a name for metal slitting equipment.

　　1. Purpose: It is suitable for longitudinal shearing of metal strips, and rewinding the slitted narrow strips into rolls.

　　2. Advantages: convenient operation, high cutting quality, high material utilization, and stepless speed regulation of the cutting speed.

　　3. Structure: It consists of unwinding (unwinding), leading material positioning, slitting and slitting, coiling (rewinding), etc.

　　4. Applicable materials: tinplate, silicon steel sheet, aluminum strip, copper, stainless steel sheet, galvanized sheet, etc.

　　5. Applicable industries: transformers, motors, home appliances, automobiles, building materials, packaging industries, etc.

　　The main components of the hydraulic system of the production line adopt high-precision components, and the electrical control adopts imported PLC program controller and touch screen for full-line functional control. It has the characteristics of high automation, good leveling quality, high cutting precision, stable and reliable performance, and convenient operation and maintenance. , One-time loading of coil material can realize the smooth completion of each process, effectively reduce the labor intensity of workers, and has a high cost performance. It is a high-performance product integrating machinery, electricity and hydraulics.
