The powder collects and solidifies while adhering to the inner wall of the bottom groove of the powder container and the bottom of the screw groove of the screw feeder.Therefore, there is an error in the amount of powder cut out, and it is particularly necessary to accurately measure the amount cut out. There was a problem in the preparation of powder dyes and other powder chemicals.

が好ましい。(Means for Solving the Problems) In order to solve the above problems, in the present invention, a screw feeder 2 for powder cutting is horizontally provided at the bottom of a powder container 1, and a motor is provided above the screw feeder 2. The driving stirring shaft 3 is provided in parallel with the screw feeder 2,
A blade plate 5 parallel to the stirring shaft 3 is fixed to the tip end of an arm 4 fixed to the stirring shaft 3, and the screw groove 2b of the screw feeder 2 is not fitted into the space above the screw feeder 2. A large number of hard spheres 6 are put in so that the hard spheres 6 are agitated with the powder 10 as the stirring shaft 3 rotates. The material of the hard sphere 6 is preferably ceramics or steel.

Then, when the stirring shaft 3 rotates, the blade plate 5 causes the powder 10 in the powder container 1 to move.
When the blade plate 5 reaches below the stirring shaft 3, the blade plate 5 moves at a right angle to the screw feeder 2 and positively pushes the powder 10 into the screw groove 2b. Then, a large number of hard spheres 6 are agitated with the powder 10 by the blade plate 5, and the hard spheres 6 are mixed with the inner surface of the powder container 1 and the screw feeder 2.
The powder 10 that is trying to adhere to these is knocked off, and the bottom of the powder container 1 and the screw groove of the screw feeder 2
The powder 10 in contact with the bottom of 2b is constantly updated. However, when the hard ball 6 is too small compared to the width of the thread groove 2b, the hard ball 6
When the hard sphere 6 is too large and is bitten into the thread groove 2b, the purpose of preventing adhesion cannot be achieved. For example, when the width of the thread groove 2b is 4 mm, the preferable diameter of the hard sphere 6 is 5 to 30 mm, particularly 10 to 20 mm.
