Example implementations can be implemented in any of various forms, and are not limited to the specific implementations described herein; rather, specific implementations are provided as examples in order to satisfy patent law requirements. Various features, aspects and alternatives can be implemented in one or more of the example implementations. In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the implementations. However, various implementation can be practiced without some or all of these specific details.

In addition, the terms "first", "second", and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0026] In the continuous coating manufacturing process of film, paper, battery electrode sheet, adhesive tape and other coiled materials, unwinding, coating, drying and winding constitute the key processes of the production line; among them, the winding process not only affects the appearance quality of the finished coiled material, such as flatness, tightness and end face neatness, but also directly relates to the stability and efficiency of subsequent slitting, cutting and banding and other deep processing links; therefore, improving the continuity and stability of the winding link has become one of the core needs of the development of winding equipment technology.
