Problems solved by technology
[0003] (1) Since the plated metal layer such as aluminum is easy to oxidize, the entire processing equipment is carried out under vacuum conditions, and the feeding mechanism for feeding the insulating film usually uses a feeding roller, and the amount of winding insulating film is limited. When the insulating film on the feeding roller is almost unwound, it is necessary to change the roller or rewind the film again, such as the vacuum coating machine for ultra-high square resistance metallized film disclosed in patent application 201320431310.X, and the one disclosed in patent application 201310324470.9 All there is above-mentioned problem in a kind of flexible winding evaporation type vacuum coater
The vacuum coating machine disclosed in the patent application 200910303404.7 realizes uninterrupted feeding of the film by loading the film on the tray and cooperating with the conveying mechanism. However, the amount of film loaded on the tray is small after all, which cannot meet the industrial mass production requirements. The convenience of feeding , timeliness needs to be improved
[0004] (2) 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
However, most of the preheating devices are fixed and cannot be adjusted, resulting in uneven preheating
Although a vacuum coating equipment disclosed in the prior art such as patent application 201520245919.7 provides a heating device that can move along an arc guide rail and realizes the angle adjustment of the heating device through a metal flexible hose, the structure uses metal flexible The physical properties of the hose itself are bent, which is inconvenient to realize automatic adjustment; in addition, the movement of the arc-shaped guide rail can drive the movement of the heating device to achieve linear two-dimensional adjustment, which cannot meet three-dimensional three-dimensional adjustment, and it is difficult to realize the control of preheating intensity. Preheating uniformity also needs to be improved
[0005] (3) The problems of the winding device are exactly the same as those of the feeding device, and the convenience and timeliness of receiving materials need to be improved

Description
technical field [0001] The invention relates to the technical field of coating machines, in particular to a preheating vacuum coating mechanism 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) Since the plated metal layer such as aluminum is easily oxidized, the entire processing equipment is carried out under vacuum conditions, and the feeding mechanism for feeding the insulating film usually uses a feeding roller, and the amount of winding insulating film is limited. When the insulating film on the feeding roller is almost unwound, it is n...
