By controlling the swing mixing mechanism to move horizontally back and forth, the mixing tank is driven to swing up and down 180 degrees. In conjunction with the vibrating stirring mechanism, the drug powder in the mixing tank is stirred, which further increases the movement of the drug powder and reduces the mixing time.

When the toothed blocks on the rotating rod contact and move relative to the rubber toothed rack, the friction will cause periodic vibration, which will cause the surface of the filter screen to vibrate. The periodic vibration force promotes the rearrangement of particles and promotes uniform dispersion of powder. This solves the problem that drug powder is prone to agglomeration during the accumulation process, resulting in uneven mixing and dispersion of powder and affecting the quality of drug powder. It achieves the beneficial effect of improving the uniform dispersion of drug powder. Attached Figure Description

[0023] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0024] like Figure 1 As shown, this utility model provides a mixing device for uniformly dispersing drug powder, including a mixing tank 1 and a U-shaped bracket 2. A feed pipe 3 is fixedly connected to one side of the top of the mixing tank 1, and a sealing cap 4 is threadedly connected to the outer wall of the feed pipe 3. A discharge pipe 5 is fixedly connected to the bottom of the mixing tank 1, and a valve 6 is provided on the outer wall of the discharge pipe 5. A swing mixing mechanism 7 is provided on the right side of the vertical outer wall of the U-shaped bracket 2. A limit slide rail 8 is fixedly connected to the lower side of the outer wall of the U-shaped bracket 2 near the swing mixing mechanism 7. A sieving assembly 10 is provided on the middle side of the inner wall of the mixing tank 1. A vibration stirring mechanism 9 is provided on the middle side of the top of the mixing tank 1, and the bottom of the outer wall of the vibration stirring mechanism 9 extends into the interior of the mixing tank 1. A control panel 11 is provided on the vertical outer wall of the U-shaped bracket 2.

[0025] The system consists of a mixing tank 1, a U-shaped bracket 2, a feed pipe 3, a sealing cover 4, a discharge pipe 5, a valve 6, a swing mixing mechanism 7, a limiting slide rail 8, a vibrating stirring mechanism 9, and a sieving assembly 10. Through the coordinated operation of the mixing tank 1, U-shaped bracket 2, swing mixing mechanism 7, and limiting slide rail 8, the mixing tank 1 can be swung up and down 180 degrees, enhancing the uniformity of the drug powder mixing in three-dimensional space. Through the coordinated operation of the vibrating stirring mechanism 9 and the sieving assembly 10, the vibrating stirring mechanism 9 drives the sieving assembly 10 to vibrate during the mixing and stirring of the powder in the mixing tank 1. The periodic vibration force promotes the rearrangement of particles and facilitates the uniform dispersion of the powder.

[0026] like Figure 2 As shown, this utility model provides a technical solution for a mixing device for uniformly dispersing drug powder: the oscillating mixing mechanism 7 includes an electric telescopic rod 71, a moving plate 72, a toothed plate 73, two connecting rollers 74, a gear 75, and a slider 76. The output end of the electric telescopic rod 71 is fixedly connected to the rear end of the moving plate 72, and the front side of the bottom of the toothed plate 73 is fixedly connected to the top of the moving plate 72. One end of each of the two connecting rollers 74 is fixedly connected to the middle side of the left and right ends of the outer wall of the mixing tank 1, respectively. The other end of the left connecting roller 74 is rotatably connected to the left end of the vertical inner wall of the U-shaped bracket 2, and the other end of the right connecting roller 74 extends through to the vertical outer wall of the U-shaped bracket 2. The right end is fixedly connected to the central axis of gear 75. The toothed blocks on gear 75 mesh with the toothed blocks on toothed plate 73. When toothed plate 73 moves horizontally back and forth, it drives mixing tank 1 to swing up and down 180 degrees through gear 75 connected to connecting roller 74, so that mixing tank 1 is upside down, promoting the uniformity of drug powder mixing. The top of slider 76 is fixedly connected to the bottom of moving plate 72. The rear end of the outer wall of electric telescopic rod 71 is fixedly connected to the outer wall of U-shaped bracket 2. The outer wall of slider 76 is slidably connected to the inner wall of limiting slide rail 8. Moving plate 72 slides along the limiting slide rail 8 through slider 76, which limits the movement trajectory of toothed plate 73.

[0027] like Figure 3 As shown, this utility model provides a technical solution for a mixing device for uniformly dispersing drug powder: the sieving component 10 includes an annular frame 1001, a filter screen 1002, and a connecting sleeve 1003. The outer side of the connecting sleeve 1003 is disposed in the middle of the annular frame 1001. The outer wall of the connecting sleeve 1003 is fixedly connected to the inner wall of the filter screen 1002. The outer wall of the filter screen 1002 is fixedly connected to the inner wall of the annular frame 1001. The outer wall of the annular frame 1001 is fixedly connected to the inner wall of the mixing tank 1. The filter screen 1002 is provided to sieve the powder and disperse agglomerated powder.

[0028] like Figure 4As shown, this utility model provides a technical solution for a mixing device for uniformly dispersing drug powder: the vibration stirring mechanism 9 includes a stirring motor 91, a rotating rod 92, two fixing rings 93, four stirring frames 94, four filter plates 95, two scraping components 96, and a support plate 97. The output shaft of the stirring motor 91 passes through the interior of the mixing tank 1 and is fixedly connected to the upper end of the rotating rod 92. The inner walls of the two fixing rings 93 are respectively fixedly connected to the upper and lower sides of the outer wall of the rotating rod 92. One end of the upper and lower stirring frames 94 are respectively fixedly connected to the left and right ends of the outer walls of the two fixing rings 93. The outer wall of the filter plate 95 is fixedly connected to the inner wall of the stirring frame 94. When the rotating rod 92 drives the stirring frame 94 to rotate, the filter plate 95 stirs the powder. The outer wall of the scraping component 96 is mirror-mounted on the outer wall of the rotating rod 92 near the surface. The upper and lower surfaces of the filter screen 1002, the lower end of the rotating rod 92 extends through to the bottom of the support plate 97 and is rotatably connected thereto. One end of the support plate 97 is fixedly connected to the inner wall of the mixing tank 1. The outer wall of the rotating rod 92 extends through the upper and lower ends of the connecting sleeve 1003 and is sleeved thereto. Several rubber racks 1004 are arranged in a ring array on the middle side of the inner wall of the connecting sleeve 1003. A retaining ring 921 is fixedly connected to the outer wall of the rotating rod 92. Several toothed blocks 922 are fixedly connected to the outer wall of the retaining ring 921 in a ring array. The outer walls of the toothed blocks 922 mesh with the outer walls of the rubber racks 1004. When the rotating rod 92 rotates, the toothed blocks 922 and the rubber racks 1004 come into contact. The viscoelastic properties of the rubber racks 1004 will intensify this friction effect. The friction force changes with speed and the correlation with static contact time will lead to significant vibration.

[0029] like Figure 5 As shown, this utility model provides a technical solution for a mixing device for uniformly dispersing drug powder: the scraping component 96 includes a ring block 961, a connecting frame 962, a spreading plate 963, and several protrusions 964. The connecting frame 962 is L-shaped, with one end of the horizontal surface of the connecting frame 962 fixedly connected to the outer wall of the ring block 961, and the bottom of the vertical direction of the connecting frame 962 fixedly connected to the top of the spreading plate 963. The upper ends of several protrusions 964 are fixedly connected to the bottom of the spreading plate 963 in a rectangular array. The inner wall of the ring block 961 is fixedly connected to the outer wall of the rotating rod 92. The lower ends of several protrusions 964 overlap the surface of the filter screen 1002. The spreading plate 963 moves circumferentially on the surface of the filter screen 1002, flattening the powder accumulated on the filter screen 1002. At the same time, the multiple protrusions 964 scrape the surface of the filter screen 1002, causing the surface of the filter screen 1002 to vibrate, promoting the powder on the filter screen 1002 to fall to the bottom of the mixing tank 1.

[0030] The working principle of this mixing device for uniformly dispersing drug powder will be explained in detail below.

[0031] like Figure 1-5As shown, when using this device to mix drug powder, firstly, connect the device to an external power source. First, feed the drug powder to be mixed into the mixing tank 1 through the feed pipe 3. Then, screw the sealing cap 4 onto the opening of the feed pipe 3. The output shaft of the stirring motor 91 drives the rotating rod 92 to rotate, causing the filter plates 95 on both sides to stir the drug powder. During the rotation of the rotating rod 92, when the toothed blocks 922 on the rotating rod 92 contact and move relative to the rubber rack 1004, the friction will cause periodic vibration. Combined with the spreading plate 963 moving circumferentially along the surface of the filter screen 1002, the drug powder on the filter screen 1002 is spread evenly, increasing the contact area between the drug and the filter screen 1002, causing the multiple protrusions 964 to scrape the surface of the filter screen 1002. This causes the surface of the filter screen 1002 to vibrate, and the periodic vibration force causes the particles to rearrange, promoting uniform dispersion of the powder. The drug powder is then sieved and shaken into the bottom of the mixing tank 1, ensuring uniform dispersion of the powder. During this process, the electric telescopic rod 71 and the stirring motor 91 are activated by the control panel 11. The output end of the electric telescopic rod 71 pushes the toothed plate 73 to move horizontally back and forth through the moving plate 72. Because the teeth on the toothed plate 73 mesh with the teeth on the gear 75, the mixing tank 1 is driven to swing up and down 180 degrees through the connecting rollers 74 on both sides, enhancing the uniformity of the drug powder mixing in three-dimensional space, reducing the mixing time of the drug powder, and improving the mixing efficiency of the drug powder. After mixing is completed, the valve 6 is opened to discharge the mixed drug powder from the discharge pipe 5.

[0032] The specific types and structures of the electric telescopic rod and stirring motor used above are all existing products, as are the specific circuit connection structure and control relationship, which are all existing technologies and will not be elaborated on further here.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
