AI Technical Summary

Technical Problem

In existing aluminum foil surface degreasing devices, the detergent is in a static state, resulting in low cleaning efficiency. Furthermore, the horizontal rinsing within the clean water chamber leads to inconsistent cleaning effects on the bottom of the aluminum foil, affecting the safety and performance of lithium batteries.

Method used

A surface degreasing device for cold-formed aluminum foil was designed, which adopts an ultrasonic degreasing box and a cleaning tank structure. The aluminum foil sheet passes through multiple turning rollers in sequence and enters the ultrasonic degreasing box for degreasing. Combined with the cleaning spray pipe, both sides of the aluminum foil sheet are cleaned at the same time. The scraper is used to remove the oil stains that are not cleaned. Finally, the foil is dried by the drying fan.

Benefits of technology

It improves the degreasing efficiency and cleaning uniformity of aluminum foil, ensures the cleanliness of the aluminum foil surface, enhances the safety and performance of lithium batteries, and has a simple, reliable, environmentally friendly, and energy-saving structure.
