Abstract

The invention discloses an adjustable film coating quality type metallized film vacuum coating machine which comprises a vacuum chamber, a feeding mechanism, a film coating mechanism and a winding mechanism; the feeding mechanism, the film coating mechanism and the winding mechanism are arranged in the vacuum chamber; a preheating mechanism is arranged between the feeding mechanism and the film coating mechanism; and a first movable plate component used for regulating the size of an opening of an evaporation boat is arranged in a top opening region of the evaporation boat. The adjustable film coating quality type metallized film vacuum coating machine has the advantages of high automation degree, uniformity in preheating, adjustable preheating quantity, suitability for processing films in multiple models and adjustable film coating thickness.

Description

technical field [0001] The invention relates to the technical field of coating machines, in particular to a metallized film vacuum coating machine with adjustable coating volume. 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 temperature on the surface 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 prehea...

Problems solved by technology

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
