Description

Technical Field

[0001] This utility model relates to the technical field of double-sided coating equipment for lithium battery electrodes, specifically a composite roller device for coating equipment. Background Technology

[0002] In battery manufacturing, rollers are often used for tensioning electrode coating. However, in some special locations, such as when coating both sides, because one side of the electrode is coated with slurry, it is impossible to use back rollers to tension and support the electrode while the slurry is still wet when coating the other side (e.g., ...). Figure 1 When the extrusion die coats the second side, the electrode sheets entering the drying oven section are inevitably shaken by the airflow, thus affecting the coating quality of the second side and the areal density of the coating. Therefore, further improvements are needed. Utility Model Content
