Problems solved by technology

With the continuous changes and needs of social requirements, it is necessary to form a pattern with a fuse structure on the coating of a metallized film, but the structure and process of the existing technology have failed to achieve the corresponding technical effect. The main key point lies in the printing technology. Failure to improve the fusion in the production of metallized films has resulted in technical limitations in the production of metallized films and application limitations of technical effects

Abstract

The invention discloses a safety film device comprising an upper guard board and a lower guard board close to a main drum. The lower guard board is equipped with a movable and scalable guide rail. The guide rail is provided with a feeding mechanism making the guide rail stretch and act. The feeding mechanism is provided with an oil feeding roller with shielding oil, a transferring roller which is tangent to the oil feeding roller and transfers the shielding oil, and a printing roller which is tangent to the transferring roller and adheres the shielding oil on the transferring roller. In an operating state, the printing roller is tangent to a thin film wound on the main drum, and prints the shielding oil on the thin film. The feeding mechanism is further provided with a scraper blade which is tangent to the printing roller, and scrapes residual shielding oil on the printing roller after the printing roller prints the shielding oil on the thin film. The guide rail is further provided with a recycling tank which is disposed below the oil feeding roller, the transferring roller, the printing roller and the scraper blade, and recycles residual shielding oil. With the safety film device, patterns with a fuse wire structure can be formed on the cladding layer of a metalized film. By using a precision printing technology, the shielding oil is printed on a base film, and a corresponding technical effect is achieved in metallization.

Description

technical field [0001] The invention relates to the technical field of coating technology in the metallized film production process, and in particular to a safety film device using precision printing technology to form a fuse structure pattern on the metallized film coating. Background technique [0002] At present, the metallized film is to design multiple disconnected small patterns in the metal area of ​​the film, and divide the metal layer into many small areas connected by very narrow metal channels (miniature fuses). When in use, when excessive self-healing occurs in a small area of ​​the film, the micro-fuse area will be disconnected first due to the small current carrying capacity of the area, so as to ensure the safety of the capacitor and play an explosion-proof role. With the continuous changes and needs of social requirements, it is necessary to form a pattern with a fuse structure on the coating of a metallized film, but the structure and process of the existing...
