Description

Technical Field

[0001] The utility model relates to the field of batteries, in particular to a roller suitable for pole piece opening and training. Background Art

[0002] In the production process of aqueous sodium-ion battery pole pieces, it is necessary to use a three-roller open-roll mill to knead some of the materials that have been kneaded into a mass and to knead them to achieve the process characteristics of the pole piece blank forming. The current open-roll mill often has joint folding and irregular pole piece blank forming during the material kneading process. After analysis, it was found that the existing roller surface is relatively smooth, and the material is irregularly clumped before entering the roller. The material will slip due to the uneven friction on the roller surface, resulting in irregular material forming, and the density difference of the formed pole piece is too large, which has a great impact on the electrode diaphragm blank forming. In addition, the surface of the roller will randomly adhere to the two sets of rollers due to the material extrusion process, resulting in the phenomenon of the head folding or repeated extrusion when the pole piece blank diaphragm comes out. For this reason, we proposed a roller suitable for pole piece opening. Utility Model Content
