Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rotary container type powder / granular mixer, and more specifically, it is mainly suitable for small-lot mixing and test sample mixing, in which rotation of the mixing container and revolution of the mixing container can be performed separately. It relates to a body mixer.

[0002]

[Prior Art]

 Conventionally, a mixing container is held in an orbital holder so that it can be rotated about its axis, and the mixing container is allowed to rotate about its central axis and to rotate along with the holder. Mixers are known.

[0003] In this type of mixer, since the powder particles perform a relatively large three-dimensional movement, macroscopic mixing can be achieved quickly, and it is excellent in mixing relatively large powder particles with each other. It is widely applied to the mixing of several powders and granules in the industry, the mixing of resin pellets in the synthetic resin industry, and toning.

[0004]

[Problems to be solved by the device]

 However, in this type of conventional powder / granular mixer, the rotation of the mixing container, that is, the rotation and the revolution, are performed by one motor power unit in an interlocking manner. Therefore, the ratio of rotation and revolution is constant and cannot be varied, so a stable and ideal degree of mixing could not always be obtained.

Further, various particle shapes of the granular material have a great influence on other physical properties, that is, bulk specific gravity, angle of repose, and flow characteristics, and as a result, are greatly related to mixing characteristics, the particle size and particle size distribution, specific gravity difference However, it is similar to the fact that the rotational speed of the revolution and the revolution suitable for each case is required by fully grasping the fluidity.

[0006]

[Means for Solving the Problems] The present invention has been made to solve the above problems, and is configured as follows. That is, the gist of the present invention is that the upper arm having a rotatable upper holder is detachably attached to the upper end clamp of the gear cylinder box in which the cylinder axes are integrally connected at a right angle, and the lower arm has a rotation corresponding to the upper holder. A holding yoke for a mixing container integrally provided with lower arms each having a free lower holder, a main body case in which a tubular shaft of the holding yoke is rotatably horizontally installed, and the tubular shaft and the cylindrical shaft inserted therethrough. It consists of two geared motors whose rotating main shafts are individually connected, and a transmission mechanism for rotating the lower holder by the rotating main shafts. The rotation of the mixing container held between the upper and lower holders is about its central axis. The granular powder mixer is characterized in that the rotation and the revolving rotation around the cylinder axis as the axis can be individually performed.

Next, the present invention will be described in detail with reference to the drawings with reference to the following embodiments.

A lower arm 23 having a lower holder 30 is a holding yoke of a mixing container 40 integrally provided with each other. A rotary main shaft 8 is inserted into the cylindrical shaft 4 and is rotatably provided via bearings 9 and 10. The cylindrical shaft 4 of the holding yoke 42 is rotatably horizontally mounted on the bearing case 3 via bearings 5 and 6. Reference numeral 7 is an oil seal. A bevel gear 11 is wedged at the left end of the rotating main shaft 8 and a pulley 13 is wedged at the right end thereof. Further, a pulley 12 is wedged at the right end of the cylinder shaft 4. Two geared motors 14 and 15 are provided in the main body case 1, and belts 18 and 19 are wound between the respective pulleys 16 and 17 and the pulleys 12 and 13, respectively. The shaft 4 and the rotary main shaft 8 inserted through the shaft 4 are individually connected. A rotating driven shaft 26 is mounted in the gear cylinder box 20 of the holding yoke 42 via upper and lower bearings 24, 25. The rotating driven shaft 26 has a bevel gear 27 that meshes with the bevel gear 11 at an upper portion thereof. However, the adjusting wheels 28 are respectively wedged at the lower ends. Further, a belt 32 is wound between the pulley 29 and the pulley 28, which are wedged to the lower end of the shaft 31 of the lower holder 30. A transmission mechanism A 1 for rotating the lower holder 30 is constituted by the rotating main shaft 8. Two vertical projecting shafts 34, 34 are provided on the lower surface of the other end of the upper arm 33 having an upper holder 35 on the lower surface of one end. Then, the upper arm 33 inserts the two protruding shafts 34, 34 into the two insertion holes of the clamp 21, respectively, sets the position at a desired height, and clamps the two knobs 22 for clamping. It has become. 36 is a pin, 37 and 38 are bearings, 39 is a case, and 41 is a cap of the mixing container 40.

[0009]

[Action]

 The mixing container 40 containing the powdery or granular material to be mixed is held by the holding yoke 42 so as to be held by the upper and lower holders 35 and 30 as shown in the drawing. Therefore, when the geared motor 14 is first rotated, the cylinder shaft 4 is rotated via the band 18 so that the holding yoke 42 rotates about the rotation main shaft 8 and the mixing container 40 rotates together with the holding yoke 42. Make a revolution. In this case, the bevel gears 11 and 27 have the same number of teeth, the rotating main shaft 8 does not rotate, and the mixing container 20 does not rotate on its own axis even if the holding yoke 42 rotates. Next, when the geared motor 15 is rotated, the rotary main shaft 8 is rotated via the belt 19, and the rotary driven shaft 26 is rotated via the bevel gears 11 and 27. The holder 30 rotates, and the mixing container 40 rotates (rotates) around its central axis.

[0010]

[Effect of the device]

 Since the mixer of this invention has the above structure, it can be easily used for mixing small lots and mixing test samples by diverting ready-made glass bottles as a mixing container.

In particular, in this mixer, the rotation of the mixing container held between the upper and lower holders about its central axis and the rotation of the holding yoke about the cylinder axis are two independent rotations. Since each can be rotated individually by a geared motor, the mixing speed can be increased by the optimum rotation speed and the optimum rotation ratio, and at the same time a stable and good mixing degree can be obtained according to the physical properties of the powder or granules. And so on.
