A kind of vacuum aluminum-plating machine
Technical field
The invention belongs to field of mechanical technique, are related to a kind of vacuum aluminum-plating machine.
Background technique
Aluminizer is multiple in one kind that Plastic film surface plates one layer of very thin metallic aluminium and is formed using special process
Flexible packing material is closed, the processing method of most common of them is when the vacuum aluminum-coated method of number.Since it had not only had the characteristic of plastic film, but also
Characteristic with metal is a kind of cheap beauty, function admirable, practical packaging material.
Vacuum aluminum-plating machine has aluminize room and coiling chamber, and coiling chamber and room of aluminizing are because the presence of vapor affects its room
Interior vacuum degree is then needed that vapor is released using air-extractor or vapor condensation is directly become solid water, if
It then will increase time of the forvacuum before plated film with the air-extractor steam that goes to draw water, reduce the use effect of vacuum aluminum-plating machine
Rate, in practical application in industry, vacuum aluminum-plating machine is since coiling chamber is connected to the room of aluminizing, so integral device is very high
It is expensive, if economic benefit necessarily declines after the service efficiency decline of vacuum aluminum-plating machine.
During being aluminized using vacuum aluminum-coated method, aluminium film lacks necessary drying during aluminizing equipment transmission
Device will affect the effect of aluminizing of product, and aluminium film, which is easy corrugation, influences product quality.
