A screw hose 521 is mounted at the outlet of the lower end of the powder bin 52, an opening 5211 is formed in the side wall of the lower end of the screw hose 521, a communicating pipe is arranged between the screw hose 521 and the pressure-air injection nozzle 512, one end of the communicating pipe and the screw hose 521 are connected to the opening 5211 in the side wall of the lower end of the screw hose 521, the other end of the communicating pipe and the pressure-air injection nozzle 512 are connected to a suction inlet 51221 of a mixing chamber 5122 of the pressure-air injection nozzle 512, so that the powder bin 52 is communicated with the pressure-air injection nozzle 512, and powder is sucked into the pressure-air injection nozzle 512. A stirring rod 526 is arranged in the screw hose 521, and a second motor (not shown) drives the stirring rod 526 to rotate, so that powder is prevented from being stopped in the screw hose 521 and being blocked; and the second motor can be in stepless speed change, so that the powder conveying amount can be controlled according to actual requirements.
After the dusting device 5 is started, compressed air enters the receiving chamber 5121 of the pressure air injection nozzle 512, under the action of air flow injection, negative pressure is formed near a suction port 51221 of the mixing chamber 5122, so that powder flowing into the screw hose 521 from the powder bin 52 is sucked into the mixing chamber 5122, the powder and the compressed air are mixed and then enter the pressure expansion chamber 5123, the air flow pressure is increased and the speed is reduced in the pressure expansion chamber 5123, an air-powder mixture is sprayed out through a plurality of small holes at an outlet of the pressure expansion chamber 5123 and uniformly sprayed on the vibrating screen 513 at the lower end of the dusting chamber 511, and the vibrating screen 513 moves linearly under the action of the two parallel vibrating motors 514, so that the powder is uniformly spread on the tobacco sheets, and the powder is prevented from being distributed in a dotted manner.
Due to the process requirements, each dusting is generally 35-200 meshes, and due to poor powder flowability, the dusting is easily performed by a common dusting device 5, so that the material uniformity of the tobacco sheet is reduced. According to the powder scattering device 5, the pressure-air injection nozzle 512 is combined with the vibrating screen 513, powder is fully dispersed and is not adhered through the pressure-air injection nozzle 512, and then the powder is continuously and uniformly scattered on the tobacco sheets through the linear motion of the vibrating screen 513, so that the powder with different formulas spread on the tobacco sheets is more uniform, and the material of the tobacco sheets is more uniform.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
