Description

Technical Field

[0001] The invention relates to the technical field of aluminum veneer production, in particular to a manufacturing process of a pre-roller-coated stone-grained aluminum veneer. Background Art

[0002] The entry of low-grade aluminum-plastic composite panels has damaged the overall image of aluminum-plastic composite panels, making people more enthusiastic about single aluminum panels. More and more architects and owners are choosing aluminum veneers. However, due to the disadvantages of single-panel spraying, such as difficult to control color difference, uneven film thickness, and excessive waste of paint, pre-rolled aluminum veneers have gradually become popular.

[0003] In addition to its beautiful decoration and natural atmosphere, stone-grained aluminum veneers are more importantly used to reduce the mining of raw stone. In today's era of energy conservation, the advantages of pre-rolled stone-grained aluminum veneers are becoming more and more obvious. Traditional stone decorations are of high quality, and dry-hanging stones are more dangerous. Stone-grained aluminum veneers are relatively light in weight and safer.

[0005] There are many special-shaped aluminum veneers now, such as wavy and arc-shaped aluminum veneers. However, when drying the arc-shaped aluminum veneer, the aluminum veneer needs to be placed on a transmission roller. At this time, the middle of the arc-shaped aluminum veneer is higher than the two sides, resulting in poor drying effect on both sides of the arc-shaped aluminum veneer after passing under the drying mechanism, so that the drying time is longer and the use is not convenient.
