Spraying device for aluminum strip continuous production line

Abstract

According to the spraying device for the aluminum strip continuous production line, the first supporting roller, the second supporting roller, the third supporting roller, the fourth supporting roller and the fifth supporting roller are erected in the box body, and an aluminum strip entering through the feeding port bypasses the lower portion of the first supporting roller and bypasses the top of the second supporting roller and the top of the third supporting roller; and finally, the material passes through the top of the fifth supporting roller and is discharged from the discharging opening. The first spraying pipe is used for spraying the upper strip surface of the aluminum strip, and the second spraying pipe is used for spraying the lower strip surface of the aluminum strip; through the design of a first suction cover, a second suction cover, a second collecting pipe and a suction pump, the mode that air flow on the surface of the aluminum strip is accelerated through suction is adopted, and therefore the mild air drying effect is achieved; and a first light curing mechanism is arranged on the outer side of the third supporting roller, a second light curing mechanism is arranged on the outer side of the fourth supporting roller, the outer side of the bent area of the aluminum strip is subjected to covering irradiation, a coating is reinforced and dried through a UV light pipe, and the drying effect of the coating is improved.

Description

technical field [0001] The invention relates to the field of processing and production of aluminum strips, in particular to a spraying device used in a continuous production line of aluminum strips. Background technique [0002] Aluminum and aluminum alloys are currently one of the most economically applicable materials that are widely used. Since 1956, the world's aluminum output has surpassed that of copper, and it has always ranked first in non-ferrous metals. The current production and consumption of aluminum (calculated by ton) is second only to steel, and has become the second largest metal used by human beings; moreover, aluminum resources are very abundant. According to preliminary calculations, the mineral reserves of aluminum account for more than 8% of the earth's crustal constituents. , Aluminum strip sheet is a commonly used aluminum structure at present, which can be processed by cutting, stamping, bending and other processing methods to produce the required p...

The current production and consumption of aluminum (calculated by ton) is second only to steel, and has become the second largest metal used by human beings; moreover, aluminum resources are very abundant. According to preliminary calculations, the mineral reserves of aluminum account for more than 8% of the earth's crustal constituents. , Aluminum strip sheet is a commonly used aluminum structure at present, which can be processed by cutting, stamping, bending and other processing methods to produce the required products; during the production process of aluminum strip sheet slag, the surface needs to be coated accordingly Coating material, in order to play the corresponding protective function; At present, the aluminum strip thin plate is conveyed by supporting rollers, and various processes such as coating, drying, and filming are carried out during the conveying process; however, because the aluminum plate has certain Weight and long-distance transportation require multiple support rollers. If the sprayed coating of the aluminum strip is not dry, it will be structured with the support rollers, which may cause damage to the sprayed coating. Therefore, it is unreasonable to spray the upper and lower belt surfaces simultaneously; and , direct drying may cause uneven temperature and different coating drying conditions, and may also cause coating cracks in the subsequent transportation and bending process, which will affect product quality
