Description

Technical Field

[0002] Cold spraying technology is an advanced surface coating process that uses high-speed sprayed powder materials to coat the target surface at room temperature. This technology accelerates the powder material to supersonic speed and then combines it with a specific nozzle structure to produce strong impact and friction with the substrate surface during the spraying process, thereby achieving firm adhesion of the coating. During the cold spraying process, some powder materials are likely to remain on the object, so it is necessary to design a powder material recycling device for cold spraying.

[0003] After searching, the patent number is CN216678775U, which discloses a powder recovery device for powder spraying. The spraying direction of the spray gun body can be determined by a camera device, and then the direction of the fan can be adjusted by a controller to control the fan horizontal adjustment mechanism and the recovery box position adjustment mechanism, so as to cooperate with the spray gun body to achieve high-efficiency powder recovery, effectively improving the powder recovery efficiency of the prior art. However, in the existing cold spraying process, some powder coating will still remain on the surface of the object after spraying, but the excess powder coating will be cleaned up, which is relatively wasteful of powder material.
