Gun rack 4 and spray gun 5 are installed on the lifter 3, and spray gun is fixed on the gun rack. When spraying, the suspension chain drives the workpiece to pass through the vertical powder spraying room slowly, and the up and down movement of the elevator drives the gun frame to move up and down. Most of the powder sprayed by the spray gun is adsorbed on the surface of the workpiece, and a small part of the sprayed powder is not adsorbed on the surface of the workpiece. Part of the powder is sucked into the cyclone separator by the vacuum exhaust pipe for separation, and part of it freely falls to the bottom of the powder spraying chamber. When the system changes color, the plastic film on both sides of the vertical powder spray booth is automatically replaced with a new plastic film that does not adhere to the powder. It is difficult to clean the V-shaped opening of the vacuum exhaust pipe. It needs to be cleaned manually. Hold a plastic air pipe with a length of about 9 meters. During the cleaning process, the powder is blown up by the airflow and falls to the bottom of the powder spraying room, so the cleaning personnel must be about 3 meters away from the powder spraying room and wear dust-proof equipment. This cleaning method mainly has the following disadvantages: 1. It is difficult to clean up, and it takes a long time to change the color;

5. Specific implementation

As shown in Figure 2, Figure 3, Figure 4, Figure 5, Figure 6, Figure 7, and Figure 8, the vertical powder spraying room is mainly composed of a vacuum exhaust pipe 1, a plastic film 2, a lift, etc. The workpiece is sprayed, and the longest sprayed workpiece can reach 7 meters, which makes the height of the powder spraying room reach about 9 meters. Gun frame 4 and spray gun 5 are installed on the elevator 3, and spray gun 5 is installed on the gun frame 4.

The pneumatic cleaning device of the vertical powder spraying room of the present utility model includes a lifter 3, a gun frame 4, a cylinder 6, a gun rod 7, a cleaning nozzle 8 and an air pipe, and the gun frame 4 and the cylinder 6 are installed on the lifter 3 and can move vertically up and down , the cleaning nozzle 8 is installed on one end of the gun rod 7, the other end of the gun rod 7 is connected with the cylinder 6, the gun rod 7 is driven by the cylinder 6 to move horizontally back and forth, the middle part of the gun rod 7 is supported and installed on the center of the gun frame 4, and the cleaning nozzle 8 is input with high pressure through the air pipe The air blowing hole 9 is arranged at the front end of the cleaning nozzle 8. During operation, the lifter 3 drives the gun frame 4 and the cylinder 6 to move up and down, so that the gun rod 7 and the cleaning nozzle 8 reach a certain height, and the cylinder 6 drives the gun rod 7 to move back and forth laterally to drive the cleaning nozzle 8 After reaching a suitable position, feed high-pressure air into the cleaning nozzle 8 to automatically clean the vertical powder spraying room. The gun bar 7 middle part is supported and installed in the gun frame 4 center, and the front end of the cleaning nozzle 8 is opposite to the V-shaped opening of the vacuum exhaust pipe 1 of the powder spraying room. Automatic sensor is installed on the cleaning nozzle 8, and whether there is object in the front of induction cleaning nozzle. The cleaning shower head 8 is V-shaped, and has some ventilation holes 9. Gun bar 7 afterbody is by connecting air pipe with clamp and air pipe feeds compressed air. The several ventilation holes 9 of the cleaning nozzle 8 are arranged in one or more rows. One or more cleaning units made up of cylinder 6, gun shaft 7, cleaning nozzle 8 and air pipe can be set. The elevator 3, the cylinder 6, and the automatic sensor are connected to a central control unit, and the automatic sensor inputs a detection signal to the central control unit, and the output terminal of the central control unit drives the elevator and the cylinder to move.
