Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile surface treatment, and in particular to a system and method for aluminum profile surface treatment based on circulating conveyance of a containing basket. Background Art

[0002] Aluminum profiles are made by hot extrusion of rods containing aluminum and other metal elements. They have the advantages of light weight and high strength. They are widely used in many fields such as building decoration, automobile manufacturing, medical equipment and chemical equipment. Aluminum profiles formed by hot extrusion are very susceptible to corrosion damage in humid, salty and dusty environments, and an oxide film is formed on the surface. The oxide film is loose, porous, uneven and discontinuous, and cannot be used as a protective layer on the aluminum surface. In order to improve the corrosion resistance of the aluminum alloy surface and improve its decorative and functional properties, aluminum profiles must be surface treated before hot extrusion. In the surface treatment process, the surface sandblasting is first required to remove impurities, sharp corners, etc. on the surface of the aluminum profile, and then subsequent surface chemical treatment is carried out on this basis.

[0003] In the current surface treatment process of aluminum profiles, one of the current treatment methods is to use a single aluminum profile for sandblasting, and then transport it to the chemical treatment line in the form of a single profile, and then go through multiple chemical processes such as degreasing, alkali etching, and sealing, and then output it. Since the sandblasting process time is short and the chemical treatment process time is long, the two processes are difficult to coordinate in terms of speed, resulting in low production efficiency. In addition, the single-piece conveying method is also prone to cause problems such as wear and scratches on the surface of the aluminum profile, and it is difficult to ensure the surface quality. Another method is to stack the aluminum profiles on the hoisting rack, send them into the sandblasting machine for sandblasting, and then send multiple aluminum profiles to the chemical treatment line for chemical treatment. Although the production efficiency is improved, multiple profiles are stacked on the holding rack, the surface after sandblasting is uneven, and the sand particles are accumulated in the gaps between the aluminum profiles and are difficult to discharge, which is easy to cause poor chemical treatment effects and pollution of the chemical treatment line. Problems such as the process requirements cannot be met. Summary of the invention
