Continuous Hydraulic Press Rolling Machine Winding And Unwinding System Equipment For Li-ion Battery Production
1.Introduction:
The rolling press is the main equipment in the continuous rolling production line. It consists of cast steel gantry frame, rolls, frequency conversion motor reducer, gas-liquid booster system, gap adjustment system, electrical control system, feeding guard plate and roll surface cleaning mechanism.
The main function is to make the electrode reach a suitable density under the rolling of the roller, and meet the pole piece thickness requirement according to the coating thickness. This equipment adopts servo to adjust the roll gap, and the line speed is adjusted by the frequency converter to realize stepless speed regulation.
