The utility model relates to 3D printing technical field, concretely is a kind of 3D printing
production line of
continuous production, including printing equipment ontology, AGV transport vehicle and
raw material powder screening box, AGV transport vehicle is installed with
raw material powder screening box,
raw material powder screening box includes box, first screening chamber, second screening chamber, screening cylinder and heating wire, AGV transport vehicle is not permanently fixed and is installed raw material powder screening box, raw material powder screening box is connected with first screening chamber and second screening chamber, first screening chamber is rotatably installed with screening cylinder, fan is fixedly installed below first screening board, the air inlet hole is established in the box corresponding fan, heating wire is fixedly installed in the air inlet hole;While guaranteeing raw material melting even when screening out standard particle size's granular raw material to use, granular raw material
surface moisture can also be removed and preheating, solve the problem that 3D printing
production line in granular raw material particle size is not even easy not completely fused and block
nozzle, leading to
production line stop.
