Its use can improve production efficiency and product quality, reduce energy consumption and environmental pollution, and reduce manual operation and management costs. It is of great significance to the production and management of enterprises. Powder mixers are also needed when mixing pharmaceutical powders.
[0003] When using the current powder mixer, the medicine material needs to be added into the mixing box from the feed port, and the auxiliary material needs to be added into the mixing box from the feed port. When the motor is working, it can drive the rotating shaft to rotate. The rotation of the rotating shaft can stir and mix the medicine material and auxiliary material in the mixing box. The evenly mixed medicine powder is discharged from the discharge pipe.
[0004] During the use of traditional powder mixers, powdered medicine is directly added into the mixing box from the feed port. The powdered medicine will partially clump during storage. Since the mixer does not screen the powdered medicine, some of the clumped medicine enters the mixer, resulting in poor powder mixing effect, which in turn affects the results of pharmaceutical experiments after the powder mixing. Utility Model Content
[0005] In response to the shortcomings of the existing technology, the utility model provides a powder mixer with quantitative discharge, which solves the problem that in the traditional powder mixer, powdered medicine is directly added to the interior of the mixing box from the feed port during use, and the powdered medicine will partially clump during storage. Since the mixer does not screen the powdered medicine, some of the agglomerated medicine enters the interior of the mixer, resulting in poor powder mixing effect, thereby affecting the results of pharmaceutical tests after the powder is mixed.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.
[0021] In the traditional powder mixer, powdered medicine is directly added into the mixing box from the feed port. During storage, some of the powdered medicine will clump. Since the mixer does not screen the powdered medicine, some of the clumped medicine enters the mixer, resulting in poor powder mixing effect, which affects the results of pharmaceutical experiments after the powder mixing.
[0022] In view of this, the utility model provides a powder mixer with quantitative discharge. Different medicinal powders are added into the screening box, and the agglomerated medicinal powder is screened by a screening device to prevent the agglomerated medicinal powder from entering the mixing box. The mixing effect of the medicinal powder is better and will not affect the pharmaceutical experimental results after the medicinal powder is mixed. The agglomerated medicinal powder after screening is discharged outward, crushed and re-added into the screening box. The screened medicinal powder enters the mixing box through the discharge port.

[0024] In the specific implementation process, it is worth noting that the mesh size of the filter 22 is not specifically limited and can meet the use requirements. The driving unit 24 drives the screening plate 21 to compress the spring 23, and the screening plate 21 drives the filter 22 to move to screen the powder.
[0025] Specifically, when using the powder mixer with quantitative discharge, the driving part 24 pushes the screening plate 21 to move when working, and the screening plate 21 compresses the spring 23 on one side. The driving part 24 continues to rotate, pushing the screening plate 21 to compress the spring 23 on the other side. The screening plate 21 drives the filter screen 22 to move back and forth, thereby screening the top powder, and the agglomerated powder is discharged outward from one side of the screening plate 21.
[0026] Example 2: By Figure 2 and 3 As can be seen, the driving unit 24 includes: a roller 241, which is attached to the outer wall of the screening plate 21; a rotating plate 242, which is rotatably connected to the front of the roller 241 through a bearing, and is rotatably connected to the inner wall of the screening box 1 through a pin; a first servo motor 243, which is detachably connected to the front of the rotating plate 242 and is detachably connected to the inner wall of the screening box 1; wherein, when the first servo motor 243 is in operation, it drives the roller 241 to squeeze the screening plate 21 through the rotating plate 242;
[0027] In the specific implementation process, it is worth noting that the model of the first servo motor 243 is SM80-D601930. When the first servo motor 243 is working, it drives the roller 241 to move through the rotating plate 242.

[0029] In the specific implementation process, it is worth noting that the powder is easy to enter the screening box 1 from the feed port 11, and the discharge port 3 discharges the powder into the mixing box 10;
[0030] Furthermore, the top of the mixing box 10 is detachably connected to a second servo motor 4, the output end of the second servo motor 4 is installed with a transmission device 5, the inner wall of the transmission device 5 is installed with a rotating rod 6, the top of the rotating rod 6 is rotatably connected to the inner wall of the mixing box 10 through a bearing, the inner wall of the rotating rod 6 is installed with two stirring blades 7, and the bottom of the mixing box 10 is installed with a discharge pipe 9;
[0031] In the specific implementation process, it is worth noting that the transmission device 5 is composed of two grooved wheels and a belt. The model of the second servo motor 4 is SM80-D601930. When the second servo motor 4 is working, it drives the rotating rod 6 to rotate through the transmission device 5. The rotating rod 6 drives the stirring blade 7 to stir and mix the powder. The discharge pipe 9 facilitates the discharge of the mixed powder.
[0032] Specifically, based on the above-mentioned embodiment 1, when the first servo motor 243 is working, it drives the roller 241 to move through the rotating plate 242, and the roller 241 squeezes the screening plate 21 to move, and the powder enters the screening box 1 from the feed port 11, and the discharge port 3 discharges the screened powder into the mixing box 10. The second servo motor 4 drives the stirring blade 7 outside the rotating rod 6 to rotate through the transmission device 5, and the stirring blade 7 mixes and stirs the powder. The discharge pipe 9 facilitates the discharge of the mixed powder.
[0033] Example 3: By Figure 1 and 4 It can be seen that a discharge device 8 is provided inside the discharge pipe 9, which includes: a cross bar 81, which is installed on the inner wall of the discharge pipe 9; an electric push rod 82, which is detachably connected to the inner wall of the cross bar 81; a tapered block 83, which is detachably connected to the output end of the electric push rod 82; a rubber sleeve 84, which is sleeved on the outer wall of the tapered block 83 and fits the inner wall of the discharge pipe 9; wherein, the electric push rod 82 drives the tapered block 83 to move upward, and the tapered block 83 drives the rubber sleeve 84 to move upward and no longer blocks the discharge pipe 9;

[0035] Specifically, based on the above-mentioned embodiment 1, the electric push rod 82 drives the conical block 83 to move when working, and the conical block 83 drives the rubber sleeve 84 to move upward. The rubber sleeve 84 no longer blocks the discharge pipe 9, and the powder can be discharged outward. The electric push rod 82 can evenly control the falling amount of the powder when working.
