Abstract

The invention discloses a coating film thickening device for metallized film processing. The coating film thickening device is sequentially provided with a preheating mechanism, a first evaporation coating device and a second evaporation coating device from front to back according to the technological process. The preheating mechanism comprises a connecting rod transmission mechanism, heaters and first retractor devices. The first evaporation coating device comprises a first evaporation drum and a first evaporator boat. The evaporator boat is arranged below the first evaporation drum. A first movable plate assembly used for adjusting the opening size of the first evaporator boat is arranged at the top opening area of the first evaporator boat. The second evaporation coating device comprises a shielding device, a second evaporator boat and a second evaporation drum. The second evaporator boat is arranged below the second evaporation drum. The shielding device is used for limiting the width and region of metal evaporated from the opening position of the second evaporator boat to fall off onto an insulation film. The coating film thickening device has the advantages that preheating is even, the preheating amount is adjustable, the device is suitable for processing films of various models, and the coating film thickness can be adjusted.

Description

technical field [0001] The invention relates to the technical field of coating machines, in particular to a thickened coating device for metallized film processing. Background technique [0002] The metallized film is the main part of the capacitor, and its quality directly affects the service life of the capacitor. At present, the metallized film is mainly processed and prepared by a vacuum coating machine, including an insulating film feeding mechanism, a coating mechanism, and a film winding mechanism after the metal layer is plated. Yet the vacuum coater of prior art has the following weak points: [0003] (1) If the existing vacuum coating machine is directly coated by the coating mechanism after being fed by the feeding device, the surface temperature of the insulating film is low, and the stability of the coating is poor. The solution is to improve the interfacial effect on the surface by setting a preheating device. However, most of the preheating devices are fixe...
