   Application  

Auto slitting machine focuses on the design and construction of lithium battery industry. The equipment is mainly used for the subsequent process of rolling, and the rolled pole slice is divided into several small rolls according to the customer's process.

Mechanism composition: the main components of slitting are divided into unwinding mechanism, deviation correction mechanism, belt connecting platform, traction mechanism, slitting mechanism, powder brushing and dust removal mechanism, tracking roller mechanism, tablet pressing mechanism, roller pressing mechanism and winding mechanism.

Cutting principle: the full closed-loop constant tension unwinding system and active winding taper tension system are adopted, with automatic deviation correction function, and the speed of the cutter is adjustable. The whole roll of pole pieces is divided into several small rolls according to the process requirements through the transmission dust removal mechanism.

   Features  

Structure: unwinding adopts air expansion shaft, magnetic powder brake constant tension control, photoelectric travel correction control; two high-quality slip shafts are used to ensure the same tension of each pole piece after slitting; angle wrapping slitting method is adopted for slitting, which is especially suitable for the slitting of zebra coated pole piece.

Process flow of equipment: passive unwinding - unwinding tension detection - automatic deviation correction control - active traction - angle wrapping slitting - winding tension detection - powder brushing dust removal - winding up

Equipment advantages: the machine is designed with multiple pole lug smoothing device to ensure that the pole lug after die cutting will not wrinkle and turn over in the cutting process.

Overall size of equipment: 3150 × 1650 × 2350mm
