Description

Technical Field

[0001] The utility model relates to the technical field of quantitative powder supply, in particular to a quantitative powder supply structure of an aluminum profile powder spraying device. Background Art

[0002] Powder spraying refers to a coating process that uses corona discharge to make powder coatings adhere to the workpiece. After powder spraying, it will go through steps such as hot melting and curing to form a coating film on the surface of the workpiece. When powder spraying the surface of aluminum profiles, a part of the powder is usually poured into the device and then powder spraying is carried out. If the powder supply is small, the powder spraying is stopped manually and powder is poured into the device again. If too much powder is placed, excess powder may remain in the device after powder spraying is completed, and it needs to be cleaned after powder spraying is completed.

When the powder reaches the required weight, the weighing device reminds the personnel, and the personnel pushes the adjustment plate to the side end to seal the bottom of the funnel, thereby limiting the material discharge. However, when the device controls the quantitative amount of powder, after the powder falls on the weighing device to reach the quantitative value, it is difficult for the personnel to immediately push the adjustment plate to the side end of the funnel during the process of manually pushing the adjustment plate to close the funnel, and some powder may still be falling onto the weighing device, which may cause excessive powder falling and inaccurate quantitative powder supply.
