Technical Field

[0001] The utility model relates to the technical field of mixing equipment, in particular to a powder mixing device. Background Art

[0002] In the food, chemical, pharmaceutical and other industries, powder or granular materials are often mixed. The prior art generally puts the powder or granular materials into a vertical mixing barrel, and mixes the powder or granular materials through a stirring blade driven by a motor. This mixing method has the following defects:

[0003] There are dead corners, and the stirring blades often cannot cover the entire mixing barrel. The powder or granular materials located in the dead corners are difficult to be stirred and mixed.

[0004] As the size of the stirring blade increases, the resistance to the stirring blade and the load on the motor will increase dramatically during stirring; however, the stirring blade and the motor have limited bearing capacity, which will limit the processing volume each time the materials are mixed. Summary of the invention

[0005] The utility model aims to provide a powder material mixing device which has no dead angle, can fully mix the powder materials and can mix a large amount of powder materials at one time.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A powder mixing device comprises: a horizontal mixing barrel, a first rotating frame located at the left end of the mixing barrel, a second rotating frame located at the right end of the mixing barrel, and a motor driving the first rotating frame and the second rotating frame to rotate; wherein, the end of the mixing barrel is provided with an opening and is adapted to have a sealing cover, and the main body of the mixing barrel is inclined downward from left to right; the rotating shaft of the first rotating frame and the rotating shaft of the second rotating frame are located in the same straight line; the part of the first rotating frame located above the rotating shaft is connected to the left end of the mixing barrel; the part of the second rotating frame located below the rotating shaft is connected to the right end of the mixing barrel.

[0010] Optionally, the first gear corresponds to the second gear one by one, and the corresponding first gear and second gear are installed on the same gear shaft; the gear shaft is rotatably installed on the bracket through a bearing; one of the two gear shafts is coaxially connected to the driving shaft of the motor.

[0011] Optionally, the mixing barrel comprises two half shells buckled together in an upper and lower manner; the two half shells are provided with connecting parts on the outer walls respectively, and a detachable connection is formed by bolts installed on the connecting parts.

[0012] Optionally, a mounting shaft for mounting blades is provided in the mixing barrel; the mounting shaft and the blades rotate synchronously with the mixing barrel; and the blades are provided with a plurality of through holes penetrating the surface thereof.

[0013] Optionally, both ends of the installation shaft are provided with connectors, and the half shell is provided with a mounting groove; the connector and the mounting groove form a limiting fit so that the installation shaft rotates synchronously with the mixing barrel.

[0014] Optionally, the blade has a sleeve portion, and is sleeved on the mounting shaft through the sleeve portion; one of the mounting shaft and the sleeve portion is provided with a limit groove extending along the length direction, and the other is provided with a limit portion extending along the length direction; the limit groove and the limit portion constitute a limit fit so that the blade rotates synchronously with the mounting shaft.

It should be understood that the mixing barrel 1 is generally detachably connected to the first rotating frame 2 and the second rotating frame 3 by bolts. Of course, according to the actual needs, the mixing barrel 1 can also be connected to the first rotating frame 2 and the second rotating frame 3 by welding or other methods.

[0032] The specific implementation of the utility model is described below: the motor 4 drives the first rotating frame 2 and the second rotating frame 3 to rotate, which can drive the horizontal mixing barrel 1 to rotate, so that the powder in the mixing barrel 1 can be turned up and down along the front and back directions. At the same time, as the first rotating frame 2 and the second rotating frame 3 rotate, the left end of the mixing barrel 1 will repeatedly rotate from the top of the rotating shaft to the bottom of the rotating shaft, and from the bottom of the rotating shaft back to the top of the rotating shaft, and the right end of the mixing barrel 1 will repeatedly rotate from the bottom of the rotating shaft to the top of the rotating shaft, and from the top of the rotating shaft back to the bottom of the rotating shaft; and when the left end of the mixing barrel 1 rotates to the top of the rotating shaft, the right end of the mixing barrel 1 just rotates to the bottom of the rotating shaft; when the left end of the mixing barrel 1 rotates to the bottom of the rotating shaft, the right end of the mixing barrel 1 just rotates to the top of the rotating shaft; in this way, the powder in the mixing barrel 1 can be turned back and forth along the left and right directions. The utility model can make the powder material turn up and down in the front-back direction, and can also turn the powder material back and forth in the left-right direction; there is no dead angle, so the powder material can be fully mixed; at the same time, there is no need to bear the resistance of powder material feedback due to stirring, which greatly reduces the load of the motor 4, and can mix a large amount of powder material at one time.
