Description

Technical Field

[0001] The utility model mainly relates to the technical field of accumulation chain spraying equipment, and in particular to an accumulation chain automatic rotating parts spraying equipment. Background Art

[0002] Existing product painting lines usually install a combination of a paint spraying room and an automatic rotating parts accumulation chain to complete the product assembly line painting work. Two sets of paint spraying arms that can slide up and down intermittently are set on one side of the inner wall of the paint spraying room to perform comprehensive painting work on the products entering the paint spraying room. The automatic rotating parts accumulation chain can drive the products to rotate after bringing them into the paint spraying room, so that the products can be fully painted.

[0003] The inventor discovered the following defects during the operation of the specific embodiment:

[0004] After the existing paint spraying room is painted, the inner wall of the spraying room away from the spraying arm will be stained with paint. Therefore, a water curtain is usually set inside the spraying room to remove the excess paint. However, due to the force of the sprayed paint, part of the paint will still pass through the water curtain and be adsorbed on the inner wall of the spraying room. The internal space of the spraying room is limited, and it is inconvenient for manual entry and exit.

[0005] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content
