Zy900-a950 automatic continuous rolling production line for battery pole piece

Roll size: φ 900 × 950mm, effective width of roll surface: ≤ 900mm, roller material: 9Cr3Mo (electroslag remelting)

Roll surface hardness: hrc67-68, roll circle run out: ≤ 0.0015mm (detected on grinder), roll installed run out: ≤± 0.002mm, roll surface roughness: RA ≤ 0.2 μ m, special treatment of roll surface: hard chromium plating, coating thickness 0.10-0.12mm

Structural form: "mouth" type integral casting frame, integral base. Main bearing: four row cylindrical roller bearing for rolling mill, linear rolling speed: 5-80m / min (stepless speed regulation), maximum pressure between two rolls: 4000kn,

Spray roller cleaning: the deceleration motor drives the roll cleaning cloth from the winding shaft to rub the rubber roller and the roll surface at a low speed from the unwinding shaft. The pressing cylinder compresses the roller cleaning cloth on the roll surface. The spray flow is controlled by the peristaltic pump, and the liquid is sprayed onto the roller cloth quantitatively. With the roll rotation and the low-speed reverse movement of the cloth, the whole roll surface is cleaned;

Stretching device: used to eliminate the wave edge produced in the rolling process of continuous or continuous strip coating electrode sheet. Tension control: PLC + low friction cylinder + servo motor closed-loop adjustment of tension, digital display, four section tension control. Laser thickness measurement: communication with hydraulic system, real-time automatic adjustment of roller press pressure, closed-loop control.

Winding and unwinding form: two shaft turntable type double position automatic roll changing mode, 6-inch shaft free expanding card head, maximum load bearing capacity: 1500kg, coil diameter range: φ 350 - φ 1000mm, maximum width: 900mm, non-stop tape connection is adopted, and the speed is 10-20m / min

Automatic production line overall size: 12500 × 5500 × 3500mm
