Lithium battery separator independent arm slitting machine

HWK-JR-FH1

Specially used for secondary slitting of lithium battery separators, each slitting unit is actively wound by an independent arm. The tension and pressure on each individual arm can be adjusted independently. Solving the problem of uneven thickness of the separator leads to low cutting yield.
