Climbing structure and coating machine

The utility model relates to the technical field of pole piece production, and particularly discloses a climbing structure and a coating machine. The climbing structure comprises a rack and a plurality of roller sets. The multiple roller sets are arranged on the rack at intervals in the climbing advancing direction. The roller group comprises an arc-shaped roller; and the arc-shaped roller is rotatably connected with the rack. By arranging the arc-shaped roller, when a stripe coating process needing longitudinal blank leaving is carried out, the component velocity intersecting with the climbing advancing direction can be generated at any point, in contact with a base material, of the arc-shaped roller, so that transverse stretching of the base material is achieved, the flattening effect on the base material is achieved, and the phenomenon that a pole piece is wrinkled is avoided. 本申请涉及极片生产技术领域，具体公开了一种爬坡结构与涂布机；其中爬坡结构包括：机架与多个辊组；多个所述辊组沿爬坡行进方向间隔布置于所述机架上；所述辊组包括：弧形辊；所述弧形辊可转动连接所述机架。通过设置弧形辊，使得在进行需要纵向留白的条纹涂布工艺时，弧形辊与基材
