700mm Calender Machine for Battery Electrode Rolling Press

Overview

Model: 700mm Calender Machine for Battery Electrode Rolling Press, Brand: TOB NEW ENERGY, item no.: TOB-BEC-700. Product origin: China; shipping port: xiamen; order (moq): 1; Payment: L/C,T/T. This electrode calender machine is described as suitable for all lithium-ion battery and supercapacitor electrode preparation. Through putting pressure on roller's crack, the dual function of pressure on loose electrodes and roll cracks prompts the drawing sheet to reach the presupposed thickness or the presupposed density. Key technical details: - Suitable system: Lithium iron phosphate, Cobalt acid lithium, Manganese acid lithium, Lithium nickel manganese cobalt and similar continuous rolling technology of positive and negative battery electrode. - Base material: Aluminum foil（12um-1.5mm）, copper foil（6um-1.5mm）, Width：150mm-700mm. - Roller mode: Two rollers up and down horizontal roll pressure, drive is on the right of the feed end. - Work pressure: Pump station provide constant pressure, suitable for high pressure rolling of positive and low pressure adjustment. - Equipment speed: No grade, the up and down roll line in the same speed. | Note: Max30m/min. - Bearing clearance automatic adjustment function: Using the cylinder to adjust, open automatically. - Control mode: PLC, touch screen digital control. - Feeding part: φ76mmX580mm Gas expanding shaft unwinding, lock valve design, with blunt air gun. - Picking platform: Stainless steel front feeding platform, the pressure plate is pneumatically lifted and scale control. - Tension control: Through the shaft pressure sensor collect signal, magnetic powder brake adjustment (adjusting range: 2.3-20kg), constant tension can be set in the scope of 0-50N. - Correcting system: Photoelectric correction, linear guide (maximum range of movement is 100mm). - Corrective action: Stepper motor (1.27NM). Stated use cases include continuous rolling and calendering of positive and negative battery electrodes for lithium-ion chemistries listed as Lithium iron phosphate, Cobalt acid lithium, Manganese acid lithium, and Lithium nickel manganese cobalt. The machine is also described as suitable for supercapacitor electrode preparation. The equipment applies controlled pressure via its rollers to adjust electrode thickness and density so that the electrode reaches the presupposed thickness or density and the lithium battery attains the preset volume energy density and battery performance.
