Description

Technical Field

[0001] The invention relates to the technical field of powder recovery, and in particular to waste recovery equipment for a powder spraying device. Background Art

[0002] The powder spraying device is a device used to spray powder coating evenly onto the surface of an object. It usually uses the principle of electrostatic adsorption to make the powder coating charged and adsorbed on the grounded workpiece surface. The powder is sprayed out through the spray gun. Under the action of the high-voltage electrostatic field, the powder particles can quickly and evenly adhere to the workpiece. During the powder spraying process, some excess powder particles will fall outside the workpiece. If these powder particles are not cleaned up in time, they will accumulate on the workbench, affecting the subsequent powder spraying process.

[0003] At present, most of the waste recovery equipment of powder spraying devices adopts dry method to recover powder, collects powder particles in the powder airflow discharged from the powder spraying room, needs to use negative pressure equipment to suck out the airflow in the powder spraying room, and the negative pressure equipment needs to use the airflow to bring the powder out, and the use of negative pressure to adsorb the powder is easy to affect the powder adsorbed on the surface of the workpiece, and even when the negative pressure is used to adsorb the powder, it is impossible to avoid the accumulation of powder on the edge of the shell. After the accumulation of this kind of powder, workers need to clean it manually, and the efficiency of manual cleaning is slow, which is easy to affect the efficiency of waste recovery.

[0025] E. In the present invention, when the powder spraying gun moves to the extreme position, the powder sprayed by the powder spraying gun is sprayed onto the surface of the workpiece, and the excess powder falls onto the surface of the trapezoidal baffle.
