Technical Field

[0001] The utility model relates to the technical field of laser cladding powder processing equipment, in particular to a laser cladding powder feeding device. Background Art

[0002] Laser cladding device is an advanced manufacturing and repair technology equipment, mainly used for material surface modification or repair. The device uses a high-energy-density laser beam as a heat source, focusing on a specific area of ​​the workpiece being processed, and simultaneously delivering pre-selected alloy powder or other materials to the laser irradiation point. When the laser contacts and heats the workpiece surface, the powder melts rapidly and forms a metallurgical bond with the substrate surface, thereby generating a cladding layer with excellent performance. The laser cladding powder feeding device is a key equipment used in the laser cladding process. It is responsible for accurately and continuously delivering the cladding powder to the molten pool while the high-energy laser beam acts on the substrate surface to form a molten pool.

[0004] To this end, we provide a laser cladding powder feeding device to solve the above problems. Utility Model Content

The dust is first filtered by the primary filter plate, which will capture larger particles and some particles in the dust. Then the high-efficiency filter efficiently intercepts and filters the fine dust to prevent tiny particles from being discharged back into the air. Finally, it is disinfected and odor-removed by the activated carbon filter plate, and then the filtered gas is discharged from the exhaust port, thereby reducing the problem of environmental pollution caused by powder splashing during the powder feeding process, thereby protecting the health of the operator and completing the use of the laser cladding powder feeding device.

[0016] 1. Through the setting of purification components, when the exhaust fan draws dust from the air inlet into the filter box, the dust is first filtered by the primary filter plate, which will capture larger particles and some microparticles in the dust. Then the high-efficiency filter efficiently intercepts and filters the fine dust to prevent the tiny particles from being discharged back into the air. Finally, it is disinfected and odor-removed by the activated carbon filter plate, and then the filtered gas is discharged from the exhaust port, thereby reducing the problem of environmental pollution caused by powder splashing during the powder delivery process, thereby protecting the health of operators;

[0017] 2.
