Description

Technical Field

[0001] The present invention relates to the technical field of spraying equipment, and more specifically, to a spraying equipment for sheet metal parts. Background Art

[0002] Electrostatic spraying of sheet metal is a widely used coating technology that uses the principle of static electricity to make powder or liquid paint evenly adhere to the surface of metal workpieces. This technology not only improves the efficiency of paint use, but also provides a more uniform and higher quality coating. Sheet metal coating can prevent metal from contacting with moisture and oxygen in the air, thereby slowing down the rust process, and can also improve aesthetics and wear resistance and high temperature resistance.

[0003] At present, sheet metal parts are either sprayed by hand-held spraying equipment or placed in a spray box for spraying. Manual spraying is not only time-consuming and labor-intensive, but also the spraying is not uniform and the spraying quality is poor. It also causes great pollution and harm to the operators. The method of hanging sheet metal parts in the spray box for spraying requires the staff to frequently put the sheet metal parts into the spray box and take out the sprayed sheet metal parts. When the number of sheet metal parts is large, it will consume more manpower and time, and the work efficiency is low and the work progress is slow.
