Abstract

The invention relates to an oil spraying device of a special coating machine for a metallized film. The oil spraying device comprises an oil bottle, an oil outlet tube, a horizontally-arranged oil control tube and a spray head; the top of the oil control tube is provided with a conical chamber, the tail end of the oil control tube is provided with a first cover plate, and the oil control tube is internally provided with a bead, a first spring, a first piston and a second spring; and the outer part of the first cover plate is provided with a first air inlet tube on which a first air valve is arranged. According to the oil spraying device of the special coating machine for the metallized film, the opening between the bead and the oil control tube is controlled by virtue of air pressure so that oil leakage of the oil spraying device is avoided; and then, the motion of a second piston is controlled by virtue of air pressure to carry out pressurization treatment on coating oil entering the spray head, so that the coating oil sprayed from the head part of the spray head has enough spraying speed and pressure, the oil spraying time is shortened, and the oil spraying efficiency and quality are improved. The oil spraying device is simple in structure, convenient to use, stable in operation, short in oil spraying time, high in oil spraying efficiency and good in oil spraying effect.

Description

technical field [0001] The invention relates to an oil injection device of a metallized thin film coating machine, belonging to the technical field of capacitors. Background technique [0002] Metallized film is an electronic component commonly used in film capacitors. Its preparation method is to vacuum evaporate a thin layer of metal on the plastic film as an electrode. In this way, the thickness of the electrode foil can be saved, and the volume of the unit capacity of the capacitor can be reduced, so the film capacitor can be easily made into a small capacitor with a large capacity. For example, the common MKP capacitor is the name of metallized polypropylene film capacitor, while MKT is the name of metallized polyethylene film capacitor. [0003] The films used in metallized film capacitors include polyethylene, polypropylene, polycarbonate, etc., and there are also laminated types in addition to wound types. This type of metallized film capacitor has a so-called self...
