A vacuum aluminum plating machine

Abstract

The invention provides a vacuum aluminum plating machine. The vacuum aluminum plating machine comprises a centralizing mechanism and a drying mechanism which are arranged on a conveying line of an aluminum-plated film; the centralizing mechanism comprises a first roller, a first guide roller, a second guide roller, centralizing rollers, high-temperature gas injection devices, a tensioning wheel I, a second roller, the aluminum-plated film, a high-temperature evaporator and gas conveying pipes; the high-temperature evaporator is connected with the high-temperature gas injection devices through the gas conveying pipes on the two sides; the drying mechanism comprises a high-temperature gas feeding cavity, a drying device casing, a belt wheel, a heat transfer wall, support seats, a discharging roller, a third guide roller, a hollow cavity, a tensioning wheel II, a tightening roller and guiding rollers; and the aluminum-plated film located on the discharging roller sequentially passes through the tensioning wheel II, the third guide roller and the guiding rollers to wind around the tightening roller. By the aid of high-temperature gas fed into the high-temperature gas feeding cavity, the condition that the product quality is affected due to the fact that the aluminum-plated film makes direct contact with a heat source is avoided, and the high-temperature gas can be recycled, so that resources are saved, and the drying effect is good.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a vacuum aluminum plating machine. 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 a special process. The most commonly used processing method is the vacuum aluminized method. Because it has both the characteristics of plastic film and the characteristics of metal, it is a cheap and beautiful packaging material with excellent performance and strong practicability. [0003] The vacuum aluminum coating machine has an aluminum coating room and a winding room. Because the existence of water vapor in the winding room and the aluminum coating room affects the vacuum degree in the room, it is necessary to use an air extraction device to extract the water vapor or directly condense the water vapor into a vacuum. into solid water, if the pumping equ...

Problems solved by technology

[0003] The vacuum aluminum coating machine has an aluminum coating room and a winding room. Because the existence of water vapor in the winding room and the aluminum coating room affects the vacuum degree in the room, it is necessary to use an air extraction device to extract the water vapor or directly condense the water vapor into a vacuum. into solid water, if the pumping equipment is used to pump water vapor, it will increase the pre-vacuum time before coating and reduce the efficiency of the vacuum aluminum coating machine. In practical industrial applications, the vacuum aluminum coating machine is due to the winding chamber and The aluminum plating room is connected, so the overall equipment is very expensive. If the efficiency of the vacuum aluminum plating machine decreases, its economic benefits will inevitably decrease

[0004] In the process of aluminum plating by vacuum aluminum plating method, the lack of necessary drying device will affect the aluminum plating effect of the product during the transmission process of the aluminum film in the aluminum plating equipment, and the aluminum film is easy to wrinkle and affect the product quality
