Abstract

The invention belongs to the technical field of thin-film capacitors, and particularly relates to a method for reducing noise of a thin-film capacitor. A winding machine used in the method comprises ashell; a motor is arranged on the front end face of the shell, an output shaft of the motor is sleeved with a first gear, and the first gear is meshed with a second gear hinged to one side of the motor. The winding roller is hinged to the front side wall and the rear side wall of the shell, and a first unwinding roller is arranged above the winding roller. A second unwinding roller is arranged onone side of the first unwinding roller; a cam is arranged between the second unwinding roller and the first unwinding roller; a rotating shaft of the cam is connected with a rotating shaft of the second unwinding roller through a belt, an air bag is arranged on one side of the cam, and an oil spraying opening is formed in the lower end of the air bag. Through the cooperation of the motor, the winding roller, the first unwinding roller, the second unwinding roller, the cam, the belt and the air bag, air generated when the polyethylene film is attached to the metal foil is reduced.

Description

technical field [0001] The invention belongs to the technical field of film capacitors, in particular to a method for reducing the noise of film capacitors. Background technique [0002] Film capacitors use metal foil as an electrode, and it is laminated with plastic films such as polyethylene, polypropylene, polystyrene or polycarbonate from both ends, and then wound into a cylindrical capacitor. Film capacitors are mainly used in many industries such as electronics, home appliances, communications, electric power, electrified railways, hybrid vehicles, wind power generation, and solar power generation. The stable development of these industries has promoted the growth of the film capacitor market. [0003] Film capacitors are an indispensable and important part of air conditioners. Film capacitors can reduce the noise of air conditioners. While people are already pursuing the cooling and power saving effects of air conditioners, they are more willing to pay for comfortable...
