The powder supply device may have a measuring cup or a hole for temporarily storing the powder supplied from the container in which the powder is stored. The powder temporarily stored in the measuring cup or the hole can be delivered to an object to be supplied with the powder, such as a cup or a bowl, to supply a predetermined amount of powder.

The powder feeder can be used for various purposes. For example, it can be used for discharging a fixed amount of powdered milk powder to take powdered milk, and it can also be used to provide a certain amount of powder necessary for manufacturing parts. Or water to provide a fluoride-containing powder for making a mouth-watering solution.

At this time, the rotary shaft of the round bar is arranged such that the inlet of the plurality of metering grooves alternately faces upward and downward as the round bar rotates, and the entrance of the metering groove intersecting with the powder supply path is located upward The powder supplied from the upper part of the powder feed path is received in the intersecting metering groove and when the inlet of the intersecting metering groove is directed to the lower side, And is supplied downward through a lower portion of the powder supply path.

At this time, the round bar includes a bolt portion screwed with the respective metering grooves to form a bottom portion of each metering groove, and the depth of the bottom portion may be finely adjusted by rotation of the bolt portion.

At this time, each of the plurality of metering grooves has a well shape having a second bottom portion, and a thread may be formed on an inner surface of the metering groove so as to be able to engage with the bolt portion.

At this time, the powder supply path and the round bar supporting portion may be arranged to cross each other.

At this time, one end of the round bar is fixedly coupled to the capacity selecting unit, and the other end of the round bar is rotatably coupled to a round bar rotation driving unit for rotating the round bar.

At this time, a coupling vane is formed on the rotation shaft to transmit the rotational force of the rotation shaft to the round bar, and an insertion groove into which the rotation shaft having the coupling vane is inserted is formed at the other end of the round bar, And may be slid within the insertion groove along the longitudinal direction of the rotary shaft.

At this time, the body is provided with a rotation position sensor for sensing the rotation posture of the round bar, and using the rotation angle of the round bar at the present time obtained through the rotation position sensor, And the rotation angle may be adjusted to coincide with the powder supply path.

At this time, on one side of the body, a rotation counter that rotates together with the round bar is provided to engage with the round bar. On the outer circumference of the rotation counter, a protruding portion intermittently connected to the elastic protrusion provided on the rotation position sensor, May be formed.
