Problems solved by technology

However, due to the color difference still exists on the surface of the metal sheet after treatment, the surface effect of some of its products cannot meet the requirements of some customers, and because the surface of the metal sheet itself is smooth, the glue will stick to the metal sheet during the surface coating process After thermal transfer or lamination, even when the metal sheet is not required, the thermal transfer layer or lamination layer is still easy to fall off from the surface of the metal sheet with the adhesive layer, resulting in the metal The sheet cannot be used normally

Embodiment 1

[0031] The specific embodiment of the present invention is as figure 1 and figure 2 As shown, a metal sheet surface treatment device includes a traction device for conveying the metal sheet, and also includes at least one set of grinding wheels, and the grinding wheel set includes a The grinding wheel and the support wheel 1 located on the other side of the metal sheet, the grinding wheel and the support wheel 1 are arranged oppositely.

[0032] In this embodiment, the metal sheet 2 is an aluminum sheet, and may also be an aluminum coil.

[0033] In this embodiment, the surfaces on both sides of the metal sheet 2 face vertically upward and vertically downward respectively, and the metal sheet 2 moves along the horizontal direction under the action of the traction device.

[0034] In this embodiment, the traction device is a first supporting wheel set 9 and a second supporting wheel set 10 . The first supporting wheel set 9 , the grinding wheel set and the second supporting...

Embodiment 2

[0050] Such as image 3 As shown, the difference from Example 1 is that the upper and lower surfaces of the metal sheet 2 are respectively polished sequentially by 3-8 sets of grinding wheels. In this embodiment, specifically, the upper and lower surfaces of the metal sheet 2 are polished by 6 sets of grinding wheels, of which 6 sets of grinding wheels are located above the metal sheet 2, and the other 6 sets of grinding wheels are located on the metal sheet. Sheet 2 below. The grinding wheels on the upper surface and the lower surface of the metal sheet 2 are the first grinding wheel 3, the second grinding wheel 4, the third grinding wheel 5, the fourth grinding wheel 6, the fifth grinding wheel 7 and the sixth grinding wheel 8 . The method of grinding on both sides is suitable for metal sheets coated on both sides, or metal sheets coated on one side and thermally transferred on the other side.

Abstract

The invention discloses a surface treatment method and device for metal sheets. Before a film coating or thermal transfer printing procedure on the metal sheets, at least one-time mechanical grinding is carried out on a to-be-coated surface of a metal sheet. The invention further discloses the surface treatment device for the metal sheets. The device comprises a traction device and at least one grinding wheel set, wherein the traction device is used for conveying the metal sheets; each grinding wheel set comprises a grinding wheel positioned on one side of a to-be-coated surface of a metal sheet and a supporting wheel positioned on one side of the other surface of the metal sheet; and each grinding wheel is opposite to the corresponding supporting wheel. By the surface treatment method and device for the metal sheets, surfaces of the metal sheets do not have color difference, oil stain or dirt; after followed-up glue coating and thermal transfer printing or film coating procedures, the thermal transfer printing layer or the film coating layer can be glued to the surface of the metal sheet well along with a gluing layer, and therefore, the quality of products is greatly improved.

Description

technical field [0001] The invention relates to the field of surface treatment of metal sheets, in particular to a surface treatment method for metal sheets that can unify the surface color of metal sheets, remove oil stains and dirt, and improve the adhesive force of an adhesive layer on the surface; It relates to a device for realizing the above processing method. Background technique [0002] At present, the market demand for metal sheets (such as aluminum sheets) is relatively large, which can be applied to interior decoration, such as ceilings, walls, etc., as well as architectural appearance, furniture, electrical appliances and other fields. After the metal sheet is formed, it cannot be used directly due to the formation of scale and rust on its surface. It must first go through the process of acid and alkali cleaning. The surface of the metal sheet can be used to increase luster or add color and pattern. However, due to the color difference still exists on the surf...
