Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile spraying, and in particular to a multi-pass pre-processing aluminum profile spraying method. Background Art

[0002] Aluminum profile spraying is a process for treating the surface of aluminum profiles, aiming to improve the aesthetics, corrosion resistance and weather resistance of aluminum profiles; aluminum profile spraying usually includes the following steps: First, the aluminum profile must be degreased to remove oil stains on the surface, because oil stains will affect the adhesion of the coating. Usually it is cleaned with an alkaline detergent and then rinsed with clean water; the primer is sprayed evenly on the surface of the aluminum profile with a spray gun. When spraying, pay attention to controlling the pressure, spraying distance and moving speed of the spray gun to ensure the uniformity of the primer coating; the aluminum profile after spraying needs to be cured to dry the paint coating and form a hard paint film. The curing temperature is generally between 180-250°C, and the curing time depends on factors such as the size and thickness of the profile, usually around 15-30 minutes;

[0003] Since the entire spraying operation process is long and there are many spraying pretreatment steps, in actual production, the spraying process has the following deficiencies: the aluminum profiles taken out from the cleaning tank need workers to take out the profiles one by one, and then air-dry them. After air-drying, they are put on the shelves one by one, resulting in many turnover processes for aluminum profiles and a long time for loading and unloading; aluminum profiles are transported individually, resulting in a long travel path for the conveying track and a large area occupied.
