Problems solved by technology

[0002] Laser is one of the major inventions of natural science in the 20th century; since the birth of the world's first laser in 1960, in the past fifty years, laser science and technology have been used in national defense, science and technology, Almost all fields such as industry, agriculture, medicine and daily life have been rapidly developed and widely used; the traditional powder feeding device for metal powder laser molding has a complex structure and poor powder feeding effect; Chinese patent application number: 201621420012.0 discloses a metal powder The powder feeding device for laser molding includes a housing with a built-in turntable driven by a motor. The turntable is provided with an annular groove for holding powder. The upper surface of the housing is provided with a feed hole and a discharge hole. The feeding hole is installed with a drop tube directly above the groove, and the top of the drop tube is connected with a silo; the inner wall of the housing is fixed with a del suction nozzle bracket, and the del suction nozzle bracket is located above the groove , the suction nozzle bracket is installed with a suction nozzle for sucking out the groove powder, and the suction nozzle is connected with a feeding pipe extending from the discharge hole of the shell; its structure is simple, the design is reasonable, and the operation is convenient. The tube falls into the groove, the turntable rotates, the powder passes through the suction nozzle, and the suction nozzle works to send the powder from the feeding pipe to the laser nozzle, the powder feeding is continuous, and the powder feeding stability is good; the metal powder laser molding feeder in the above technical solution The powder device sucks and transmits the material through the suction nozzle, which may easily lead to blockage of the material pipe and affect the normal operation of the equipment
