However, traditional powder mixing methods, such as stirring with a glass rod or a medicine spoon, often have problems such as low mixing efficiency, poor effect, and dead corners. This not only affects the accuracy of experimental data, but may also cause problems such as segregation, stratification, and agglomeration of Chinese medicine powder during the dissolution process, thereby affecting the preparation quality and user experience of the powder. Utility Model Content

[0029] The following will combine the embodiments of the utility model and the drawings of the specification to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In the description of the present invention, it should be understood that the terms "center", "vertical", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0031] A powder mixing device, such as Figure 1-Figure 3As shown, it includes a mixing barrel 10 for mixing powders, a base 20 is arranged at the bottom of the mixing barrel 10, the top surface of the base 20 is inclined and an inverted L-shaped side frame 30 is installed at one end of the top surface, a top cover 40 is installed on the top surface of the mixing barrel 10, and a rotating chassis 50 for fixing the mixing barrel 10 is installed on the top surface of the base 20; a plurality of evenly and equidistantly arranged protrusions 11 are installed on the inner wall of the mixing barrel 10; a lifting cylinder 31 is installed on the top surface of the side frame 30, and a servo mixer 41 is connected to the bottom of the telescopic rod 32 of the lifting cylinder 31, and the servo mixer 41 is installed at the center of the top surface of the top cover 40, and the output shaft of the servo mixer 41 passes through the top cover 40 and is coaxially connected to a mixing shaft 42, and the mixing shaft 42 is connected to the mixing shaft 42. A plurality of groups of stirring blades 43 arranged evenly and equidistantly are installed on the mixing shaft 42; a servo motor 51 for driving the rotating chassis 50 to rotate is installed in the base 20. By tilting the mixing barrel 10 and the base 20, three-dimensional stirring of the powder is achieved, and the mixing effect is further improved. The servo motor 51 installed in the base 20 drives the mixing barrel 10 to rotate by rotating the chassis 50, and combines with the stirring action of the servo stirrer 41 to form a composite stirring mode, which not only improves the mixing efficiency, but also ensures the uniformity of the mixing. A plurality of evenly and equidistantly arranged protrusions 11 installed on the inner wall of the mixing barrel 10 effectively increase the friction between the powder and the barrel wall, and promote the tumbling and mixing of the powder.

[0032] Furthermore, a control seat 21 is installed at one end of the base 20, and a mixer adjustment knob 23 for controlling the servo mixer 41 and a chassis adjustment knob 22 for controlling the servo motor 51 are installed on the control seat 21; through the mixer adjustment knob 23, the operator can easily adjust the stirring speed and stirring strength of the servo mixer 41 to meet the mixing requirements of different powders. The chassis adjustment knob 22 allows the operator to easily adjust the speed of the servo motor 51, and then adjust the rotation speed of the mixing barrel 10 to achieve more precise control.

[0033] It is worth noting that the mixing cylinder 10 is tilted at an angle of 10-20°, which helps the powder to flow and tumble naturally during the mixing process, reduces the accumulation of powder on the cylinder wall, and thus improves the mixing effect.

[0034] The interference fit between the mixing cylinder 10 and the rotating chassis 50 ensures the stability and reliability of the mixing cylinder 10 during rotation.

[0035] Specifically, the rotation directions of the servo mixer 41 and the servo motor 51 are opposite, which increases the complex movement trajectory of the powder in the mixing barrel 10, which not only improves the uniformity of mixing, but also helps to reduce the mixing dead angle.

[0036] In addition, the bottom area of ​​the top cover 40 is larger than the opening area of ​​the mixing barrel 10, so that the powder will not overflow from the barrel mouth during the mixing process, and the servo mixer 41 is coaxially arranged with the mixing barrel 10, so that the mixing is more uniform without dead corners.

[0037] The working principle of the powder mixing device is as follows: the operator pours the powder to be mixed into the mixing barrel 10 to ensure that the initial state of the powder is distributed as evenly as possible in the barrel, closes the top cover 40 through the lifting cylinder 31 and the telescopic rod 31 to ensure that the mixing barrel 10 is sealed during the mixing process to prevent powder leakage, starts the servo motor 51 to make the rotating chassis 50 start to rotate, thereby driving the mixing barrel 10 to rotate, and at the same time, starts the lifting cylinder 31 to make the servo mixer 41 and its stirring shaft 42 descend to the inside of the mixing barrel 10 to prepare for the stirring operation, and the rotation of the stirring blade 43 is combined with the rotation of the mixing barrel 10 to form a composite stirring mode to perform three-dimensional stirring on the powder.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
