Based on the above and in conjunction with Fig. 3 and Fig. 4, the working principle of the dust-proof device 100 for the spray booth equipment is described in detail below:

When the workpiece 300 is transported to the interior of the spray booth 200 by the workpiece conveyor 201 for spraying, a large amount of spray paint and dust 204 float inside the spray booth 200, and the right cover plate 13 and the left cover plate 12 block these spray paint and dust 204 in the spray booth. In the room 200, prevent a large amount of floating into the inside of the receiving chamber 1a; while spraying, the high-pressure blower 23 outside the spray room 200 is started, and a large amount of air is sucked in from the outside and delivered to the air supply pipe 22, Thereby forming a high-speed airflow, the high-speed airflow is sprayed from the blowing nozzle 21 to the port 11, just forming an air curtain 4 at the port 11, and the air curtain 4 just completely covers the port 11. Finally, the air flow completely flows to the spray booth 200 . When a part of spray paint and dust 204 floats into the interior of the housing chamber 1a through the port 11, it encounters the air curtain 4 at the port 11 and is just blown away by the air curtain 4 and blows away with the high-speed airflow. Flowing back to the interior of the spray booth 200 , the high-speed air flow continuously ejected by the air blowing nozzle 21 prevents the spray paint and dust 204 from entering the interior of the storage chamber 1a, thereby achieving the purpose of dust prevention. the

Because the utility model forms a closed accommodation cavity 1a by installing the left cover plate 12 and the right cover plate 13 around the workpiece conveyer 201 and the roller wiper 203, and forms a space between the two plates for The port 11 through which the workpiece rotating shaft 202 passes vertically blocks the spray paint and dust 204 outside without hindering the rotation of the workpiece rotating shaft 202 to the workpiece 300, effectively preventing the spray paint and dust 204 from adhering to the workpiece during transportation. On the machine 201 and the rubbing machine 203, and the right shielding part 13a on the side of the port 11 is provided with an air blowing nozzle 21, and the air blowing nozzle 21 can pass through the high-pressure blower 23 and the air supply pipe 22 to The port 11 blows out gas, thereby forming an air curtain 4 at the port 11, further preventing spray paint and dust 204 from entering the interior of the storage chamber 1a through the port 11, avoiding damage to the spray booth equipment, and greatly reducing The frequency of manual cleaning and daily maintenance costs have been greatly reduced. the

The working principles of the workpiece conveyer 201 and the roller wiper 203 involved in the dust-proof device 100 for spray booth equipment of the present invention are well known to those skilled in the art, and will not be described in detail here. the

What is disclosed above is only a preferred example of the utility model, and of course the scope of rights of the utility model cannot be limited with this. Therefore, equivalent changes made according to the patent scope of the utility model still belong to the scope covered by the utility model . the
