Fully automatic rolling and cutting integrated machine

I. Core Value and Process Flow 
Core Value: The traditional production line has separate processes for rolling and cutting, requiring two times of winding and transporting; the integrated machine eliminates the intermediate winding and reducing one time of material feeding and positioning, increasing the yield by 0.5%-1%, improving the efficiency by 30%+, saving 40% of space, and reducing 30% of manpower. 
Process Flow: 
Unwinding → Dust removal and iron removal → Material feeding traction / creasing → Precise rolling (hydraulic / servo opposed rollers) → Laser thickness measurement → Buffer correction → High-speed cutting (roller knife / laser) → Tension closed loop → Dual-axis winding → Automatic rewinding / labeling. 
II. Working Principle 
Rolling Principle: Servo / hydraulic drives the upper and lower rollers (hardness HRC66+), applying a pressure of 50-200T to compress the coated sheet to the target thickness (precision ±1-1.5μm), enhancing the density and conductivity of the sheet; equipped with bent rollers + constant pressure / constant gap closed loop, eliminating edge looseness and middle tightness, ensuring uniform thickness of the entire sheet. 
Cutting Principle: After rolling, the sheet passes through buffering and correction (precision ±0.1mm), then enters the high-precision roller knife (hard alloy / diamond coating, edge jump ≤10μm) for longitudinal cutting; high-end models can also choose laser cutting, without molds, and with quick changeover.
