ABSTRACT:
The quantitative supply apparatus of powder coloring agent can measure the powder coloring agent through a measuring groove provided on a rotary shaft and supply it directly to the raw material inlet opening of an injection moulding machine. The measuring groove on the rotary shaft can be adjustably changed properly in volume along a length direction. A container for the coloring agent is disposed on the top portion thereof and a hole in the bottom portion of the container is in contact, in a location covering the measuring groove, with the top portion of the rotary shaft. The coloring agent which has dropped from the measuring groove through the rotation of the rotary shaft is adapted to be introduced to the inlet opening of an ejector, and furthermore to the be supplied out of an exhaust side of the ejector to the inlet opening of the injection moulding machine through compressed air.
