1.2 Introduction to Principles
Load the rolled positive/negative electrode plates into the winding mechanism, and use power traction to feed the plates into the cutting blade group arranged according to the process specifications for cutting. The upper and lower winding mechanisms collect the divided plates into rolls, and the edge materials on both sides are collected by the edge material mechanism. The equipment is assisted by a deviation correction system, a tension transmission system, and a suction system (including blade suction) to ensure precise operation of the electrode strip, ensuring stable cutting, burrs, straightness, and other process indicators within the process range.
