The present invention relates to a scale for measuring quantitative powder having a head compensation unit. The scale for measuring quantitative powder comprises an upper storage hopper (10) storing powder and having a shutoff gate (12) formed on the lower surface to block the discharge of the stored powder, and a lower storage hopper (20) formed right under the upper storage hopper and having multiple load cells for storing measuring the quantitative powder discharged through the upper storage hopper (10). Also, the scale for measuring quantitative powder comprises a head compensation unit formed in the internal upper part of the lower storage hopper (20) on the same vertical line between the lower storage hopper (20) and the upper storage hopper (10), compensates the height of the powder in comparison with dropped hours by enabling the powder dropped by opening the shutoff gate (12) of the upper storage hopper (10) to be laminated in a narrower volume than the volume of the lower storage hopper (20) not to be widely spread on the entirely volume of the lower storage hopper (20), and coupled to the upper center of the lower storage hopper (20) on the same vertical line arranged right under the shutoff gate (12) to minimize the quantitative measuring errors of the power by minimizing the scattering of the powder since the dropped distance of the powder dropped from the shutoff gate (12), which is opened by intensively dropping the powder to the center, is reduced in comparison with the compensated height. |
