6, the vibrating feeder 200 may further include a powder supply amount control plate 260. [

The powder feed amount control plate 260 is a member that serves to keep the amount of powder accumulated on the swash plate 212 constant, and it is installed in the receiving space 210a of the feeder housing 210 in an inclined state as shown in FIG. And a discharge groove 261 is formed on one side of the swash plate 212 to discharge a predetermined amount of powder through the discharge groove 261 to keep the amount of the powder on the swash plate 212 constant.

That is, the powder supply amount control plate 260 discharges the powder corresponding to the area of the discharge groove 261 while the powder supplied from the discharge port 110 of the powder container 100 is loaded, To be constant.

Accordingly, since the powder is supplied to the swash plate 212 through the powder supply amount control plate 260, the powder can be uniformly discharged into the opening 211 while being vibrated by the feeder impactor 230.

The discharger 300 is a component that supplies powder discharged to the opening 211 of the feeder housing 210 to a nozzle (not shown).

The ejector impactor 330 is a component that provides vibration or impact to the hopper 310 so that the powder is not deposited on the walls of the hopper 310 or on the mesh plate 320 described below.

The ejector impactor 330 includes a driving motor 232 and a hammer 233 like the feeder impactor 230 described above with the vacuum chamber 400. The ejector impactor 330 is connected to the outside of the hopper 310 Impact can be provided while hitting the side.

Alternatively, the ejector impactor 330 may comprise a vibration motor 231 and may be attached to the surface of the hopper 310 to provide vibration.

Here, the hopper 310 is preferably formed to have a thickness of 0.1 to 3 mm, more preferably, a thickness of 0.5 mm so that the impact due to the hitting of the hammer 233 can be smoothly transmitted to the powder.

If the thickness of the hopper 310 is less than 0.1 mm, it may be broken or deformed by the hitting of the hammer 233. If the thickness of the hopper 310 is more than 3 mm, Can not be smoothly removed.

Further, the hopper 310 may be formed with a wall surface inclination of 20 to 90 degrees. That is, the hopper 310 may be manufactured with an inclination of 20 degrees or more, and may be formed into a tube shape while being formed with an inclination of 90 degrees.

The hopper 310 may be moved by the impact of the ejector impactor 330 as the hopper 310 is accommodated in the vacuum chamber 400 to be described later.

The mesh plate 320 preferably has a mesh size within a range of the maximum size of the powder particles to a maximum size of 100 μm larger than the maximum size of the particles.

For example, when the granule size of the fine powder is 180 μm, it is preferable that the mesh size 320 is formed within a range of 180 to 280 μm.

As the impact of the ejector impactor 330 is transmitted in a state in which the agglomerated powder agglomerates are placed on the surface of the agglomerated sheet 320, the agglomerated state of the agglomerated powder agglomerations is dissipated and supplied to the hopper 310 through the mesh holes .

The vacuum chamber 400 is a component that receives a part of the vibrating feeder 200 and the discharger 300 as shown in FIG. 1 and forms a vacuum therein.

As shown, the vacuum chamber 400 can form a vacuum inside the vacuum chamber 400 through the vacuum pressure supplied to the hopper 310 and vacuum pressure is provided through the vacuum line, Vacuum may be formed inside.

Accordingly, the powder falls smoothly without being scattered while falling into the mesh plate 320 or the hopper 310 through the gate 221 of the feeder housing 210 in a vacuum state.

As the vacuum pressure of the vacuum chamber 400 is supplied to the powder container 100 through the discharge port 110 of the powder container 100, the powder of the powder container 100 can be smoothly discharged to the discharge port 110 have.
