Feeding mechanism for metallized film processing

Abstract

The invention discloses a feeding mechanism for metallized film processing. The feeding mechanism comprises a first ascending and descending mechanism and a feeding device, wherein the telescopic end of the first ascending and descending mechanism is matched with the feeding device and is used for driving the feeding device to vertically move; a first proximity sensing mechanism comprises a first baffle plate and a first contact element; one end, with a higher position, in the first baffle plate sleeves a fixed transverse rod arranged at the upper end of a first support frame in a rotationally matching way; one end, with a lower position, in the first baffle plate is connected with the end, with the higher position, in the first contact element; one end, with the lower position, in the first contact element can be in contact with the outermost layer of an insulation film of a feeding roller in a feeding state; the first proximity switch is arranged on the fixed transverse rod relative to the baffle plate. The feeding mechanism has the advantages that the automation degree is high; the material supplementation is convenient and timely.

Description

technical field [0001] The invention relates to the technical field of coating machines, in particular to a feeding 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] 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 feeding When the insulating film on the roller is unwinding quickly, it is necessary to ch...

Problems solved by technology

[0003] 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 feeding When the insulating film on the roller is unwinding quickly, it is necessary to change the roller or rewind the film, such as the vacuum coating machine for ultra-high square resistance metallized film disclosed in the patent application 201320431310.X, and a soft winding disclosed in the patent application 201310324470.9 All evaporative vacuum coating machines have the above problems

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
