Description

Technical Field

[0001] This utility model relates to the field of coating spraying technology, and in particular to a coating spraying box for metal workpieces. Background Technology

[0002] Metal products are among the most commonly used products today. During the manufacturing and processing of metal workpieces, in order to ensure the functionality of the metal products, the metal surface is painted. After painting, the metal surface needs to be dried to keep it dry.

[0003] The prior art discloses a metal workpiece surface spraying device (201921344643.2), which includes a box body. The side of the box body is provided with a loading and unloading door. A number of drive wheels and a number of rotating supports are provided on the main shaft. A hook is provided below the rotating supports. A number of spray holes are evenly arranged on the high-pressure air pipe inside the box body. The metal workpiece inside the box body rotates on its own axis and the rotating supports revolve around the axis, so the purpose and effect of uniform spraying are achieved. However, there are still the following shortcomings. Since the spray holes are set around the box body, the rotating shaft drives the workpiece to rotate around the rotating shaft. It is impossible to spray the workpiece on the side close to the rotating shaft. Moreover, it is necessary to spray in batches and cannot spray continuously, which affects the efficiency of spraying. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned shortcomings by providing a metal workpiece coating spraying box that enables continuous spraying of metal workpieces within the spraying box, ensuring comprehensive and uniform spraying and improving spraying efficiency.

The spraying mechanism is located inside the spraying box and is used to spray the metal workpieces inside the spraying box evenly from all directions. A collection box, located inside the spray booth and directly below the conveyor mechanism, is used to collect the flying paint. The rotation interval of the conveying mechanism is the same as the lifting interval of the spraying mechanism, and the spraying mechanism is used to spray metal workpieces on the conveying mechanism without collision.

[0006] Furthermore, the conveying mechanism includes multiple pillars disposed on the top of the support and an elliptical track disposed on the pillars; It also includes a transmission belt installed within the track and a drive unit installed on the track to move the transmission belt.
