Vacuum aluminizing device and aluminizing method for packaging material

Abstract

The invention discloses a vacuum aluminizing device for a packaging material in the technical field of vacuum aluminizing. A slide rail is arranged on the top of the base, the other side of a couplingis connected to an adjusting screw, an aluminizing box body is arranged on the top of the fixed slide block, a fixed baffle plate is arranged at the right end of the aluminizing box body, an assemblygroove matched with the aluminizing box body is formed in the left side wall of the fixed baffle plate, a rubber sealing gasket is arranged in an inner cavity of the assembly groove, a negative pressure fan is arranged on the top of the fixed baffle plate, the right end of a guiding slide bar is connected to the fixed baffle plate, ceramic layers are arranged on the side walls of the inner cavityof the aluminizing box body, a plasma emitter is arranged on the top of the inner cavity of the aluminizing box body, an aluminum box is arranged in the bottom of the inner cavity of the aluminizingbox body, and a graphite heater is arranged on the top of the aluminum box. The vacuum aluminizing device disclosed by the invention is reasonable in structural design, and can improve the adhesive force between aluminum steam and the surface of the packaging material effectively, so that the aluminizing effect is improved, and the production cost can be lowered.

Description

technical field [0001] The invention relates to the technical field of vacuum aluminum plating, in particular to a vacuum aluminum plating device and an aluminum plating method for packaging materials. Background technique [0002] Aluminized film is a kind of composite flexible packaging material formed by coating a layer of extremely thin metal aluminum on the surface of plastic film by special technology. The metal aluminum is melted and evaporated, so that the aluminum vapor deposits and accumulates on the surface of the plastic film, so that the surface of the plastic film has a metallic luster. Since aluminized film has the characteristics of both plastic film and metal, it is a cheap and beautiful packaging material with excellent performance and strong practicability. Aluminized film is widely used in composite packaging. At present, it is mainly used in biscuits. Such as dry, puffed food packaging and the outer packaging of some medicines and cosmetics.

AI Technical Summary

Problems solved by technology

[0003] Although the common vacuum aluminum plating device is conducive to the diffusion of aluminum vapor, it can increase the contact area between the film and aluminum vapor, make the aluminum vapor adhere to the film quickly and evenly, and improve the efficiency of film aluminum plating. However, in this vacuum aluminum plating device Without a sealing device, a vacuum state cannot be quickly formed, and the vacuum degree is poor. Therefore, it is necessary to design a vacuum aluminum plating device for packaging materials
