Zy800-a850-q production line of battery electrode

Roll specification: φ 800 × 850mm, effective width of roll surface: ≤ 800mm, roller material: 9Cr3Mo (electroslag remelting), roll surface hardness: hrc67-68

Roll circular run out: ≤ 0.0015mm (detected on grinder), roll installed run out: ≤ ± 0.002mm, roll surface roughness: RA ≤ 0.2 μ M

Structural form: "mouth" type integral casting frame, integral base. Main bearing: four row cylindrical roller bearing for rolling mill, linear rolling speed: 3-60m / min (stepless speed regulation), maximum pressure between two rolls: 4000kn

Slitting after pressing: it is used to cut the continuous strip coated battery plates into 2-4 strips along the strip direction. Double shaft winding: the pole piece which has been cut longitudinally is collected on the upper and lower slip shafts, and there is a pressing roller

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.

Overall dimension of continuous rolling line: 7700 × 3600 × 3000mm
