Description

Technical Field

[0001] The utility model relates to the technical field of raw material recycling equipment for thin-film capacitors, and particularly relates to a stripping device for thin-film capacitor film coils. Background Art

[0002] A thin-film capacitor is formed by winding a polymer dielectric metallized film on a film coil. Different specifications of thin-film capacitors are regulated by designing the film thickness and the number of turns of the polymer dielectric metallized film. Since the thickness of the film coil does not necessarily match the designed number of turns of the thin-film capacitor, there will be a remaining part of the metallized film head during the preparation of the thin-film capacitor, which is not enough to prepare a complete thin-film capacitor core. The treatment of this part of the metallized film head has become a problem. If it is directly discarded, the flying metallized film touching the high-voltage wire will pose a safety hazard. Secondly, since the materials of the metallized film and the film coil are different, direct melting and recycling will result in too many impurities in the film coil, unable to meet the recycling requirements.

[0003] In summary, for environmental protection and resource recycling, when recycling the film coil, the metallized film needs to be first stripped from the film coil. Therefore, a device is needed to strip different specifications of metallized films from the film coil. Content of the Utility Model

The multiple support blocks are evenly distributed at intervals along the circumferential direction of the roller. The support blocks are in contact with the outer wall of the airbag, and the airbag is connected to an external air charging and discharging device through a pipeline.

[0031] The film coil stripping mechanism 3 includes a cutting component and a moving component. The cutting component is installed on the moving component, and the moving component drives the cutting component to move axially along the film coil, so as to axially cut the metallized film on the film coil to be stripped, realizing the separation of the metallized film from the film coil.
