辊压装置和电极生产设备
By setting multiple rollers in the roller pressing device and controlling them separately by a drive component, the roller gap width can be adjusted independently, which solves the problem that the existing roller pressing device cannot meet the pressure difference requirements of different process stages, and ensures the composite quality of the membrane and the current collector.

AI Technical Summary
Existing roller pressing devices cannot achieve independent adjustment of different roller pressing zones, making it difficult to meet the differentiated pressure requirements of different process stages, resulting in difficulty in guaranteeing membrane quality and composite quality.
By setting up multiple first rollers and second rollers, each controlled by a first drive unit and a second drive unit respectively, the widths of adjacent first roller gaps and second roller gaps can be independently adjusted, thereby achieving independent adjustment of film thinning pressure and composite pressure.
This ensures the quality of the composite between the membrane and the current collector, and improves the stability of the membrane thickness and the composite quality.
