Description

Technical Field

[0001] The utility model relates to the technical field of metallized film production, in particular to a metallized film unwinding and flattening device. Background Art

[0002] Metallized film is the main material of film capacitors. Metallized film has the characteristics of strong ductility and relatively softness. After the processing of the metallized film is completed, a winding device is required to wind the metallized film. Through the winding form, the metallized film is more convenient to transport and store during the production process. The metallized film is mainly wound on the winding roller. Before the metallized film is used, the unrolled metallized film is bent. These bent metallized films are not conducive to the subsequent processing of the film. The unrolled metallized film needs to be flattened. , so that the treated metallized film remains horizontal. When the metallized film is flattened, the metallized film usually passes directly between the flattening rollers to complete its flattening. However, since the metallized film directly passes through the flattening rollers, it is difficult for the flattening rollers to be in a cyclic and gradual adaptation process during flattening. Direct flattening may cause excessive force on the flattening rollers, thereby causing damage. In addition, when the metallized film is unrolled, the position of the metallized film is often offset, thereby affecting the quality of its flattening. For this reason, we propose a metallized film unwinding and flattening device. Utility Model Content
