The invention provides a material spraying device which is suitable for spraying fine particle materials and wide in application range. A material pipe is arranged in the middle of the material spraying device, and an air pipe is sleeved on the material pipe. A cavity body formed by the material pipe and the air pipe is packaged by a front end cover and a rear end cover. The rear end of the material pipe is connected with a material sending pipe, and the rear end of the air pipe is connected with an air supply pipe. The front end of the material pipe is provided with a material spraying nozzle, and the front end cover is sleeved on the material spraying nozzle and matched with the material spraying nozzle. The front end of the front end cover is concentrically provided with a whirlwind piece and a horn opening. An inner hole is formed in the center of the whirlwind piece, a plurality of small holes are formed in the circumference of the outer ring of the inner hole, and the inner hole is communicated with the small holes through grooves. The inner hole of the whirlwind piece is sleeved on the material spraying nozzle, and a gap is reserved between the inner hole of the whirlwind piece and the material spraying nozzle. The material spraying nozzle is columnar, and a plurality of material grooves are axially formed in the peripheral wall of the material spraying nozzle.
Description
technical field [0001] The invention relates to a material spraying device, which can be applied to the fields of chemical industry, automobile manufacturing, construction and the like. Background technique [0002] At present, the existing spraying device adopts the nozzle type structure, and its spraying material has large particles and poor fineness uniformity, which cannot meet the requirements of fine particles such as toner, so it is necessary to improve the existing spraying device.
