[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figures 1-5 The device shown is a uniform mixing device for medicinal powder, which can achieve uniform mixing of medicinal powder and filter out large particles in the medicinal powder, thereby improving the processing quality of the medicinal powder.

[0021] refer to Figure 1 As shown, the powder uniform mixing equipment includes a workbench 1, a power chamber 2 is arranged above the workbench 1, a mixing hopper 3 is arranged above the power chamber 2, and a packaging conveyor line 5 is woven on one side of the mixing hopper 3 for conveying bottles 6.

[0022] refer to Figures 1 to 5 As shown, a guide surface 7 is provided on the inner wall of the mixing hopper 3. The guide surface 7 is spirally distributed and extends from the bottom of the mixing hopper 3 toward the top of the mixing hopper 3. A cover 4 is provided above the mixing hopper 3. A discharge port is provided on the cover 4. A material pump is provided at the discharge port. The material pump corresponds to the bottle 6 on the packaging conveyor line 5. During operation, the medicine powder is added to the inside of the mixing hopper 3. After the medicine powder is mixed, it is sucked out by the material pump. The medicine powder moves along the trajectory of the guide surface 7 to achieve the purpose of mixing and conveying at the same time. Finally, the medicine powder is added into the bottle 6 through the discharge port to achieve the purpose of filling.

[0023] The material of the mixing bucket 3 should be selected to be wear-resistant and corrosion-resistant, such as stainless steel or aluminum alloy, to ensure the durability and stability of the equipment.

[0024] Furthermore, a motor 9 is installed inside the power chamber 2. A drive shaft 10 is fixedly installed on the upper shaft of the motor 9. The drive shaft 10 extends movably into the interior of the mixing hopper 3. A connecting rod 11 and an upper baffle 14 are fixedly installed at one end of the drive shaft 10 that extends movably into the interior of the mixing hopper 3. The upper baffle 14 is located above the connecting rod 11. A stirring plate 12 is fixedly connected to the end of the connecting rod 11 that is away from the drive shaft 10. The connecting rod 11 has a rod-shaped structure, and the upper baffle 14 has a disc-shaped structure. The radius of the upper baffle 14 is greater than the length of the connecting rod 11. A retaining ring 13 is fixedly connected to the outer ring of the upper baffle 14. The retaining ring 13 extends downward and has a circular structure. Air holes 15 are provided on the upper baffle 14. Multiple air holes 15 are provided and are evenly distributed. The air holes 15 penetrate the upper and lower surfaces of the upper baffle 14. A filter cotton 16 is fixedly attached to the lower surface of the upper baffle 14. The length and width of the stirring plate (12) can be adjusted according to the size of the mixing hopper (3) to ensure the stirring effect.

[0025] When the motor 9 drives the transmission shaft 10 to rotate, the connecting rod 11, stirring plate 12, upper baffle 14 and baffle ring 13 rotate synchronously. During the rotation of the stirring plate 12 driven by the connecting rod 11, a vertically distributed vortex is formed, which makes the powder in the mixing hopper 3 fully mixed. When the powder is conveyed upward, it is blocked by the upper baffle 14 and collected in the inner ring of the baffle ring 13. As the baffle ring 13 rotates, the finer powder centrifugally diffuses from the lower end of the baffle ring 13 to the bottom of the mixing hopper 3. Since the vortex phenomenon generated around the stirring plate 12 impacts the bottom surface of the upper baffle 14 upward, it forms a downward vortex phenomenon on the periphery of the stirring plate 12 after being guided by the reverse direction of the bottom surface of the upper baffle 14. This causes the powder centrifugally diffused from the lower end of the baffle ring 13 to enter the bottom inner ring of the mixing hopper 3. When the material pump is started, the powder is mixed and conveyed out again by the guide surface 7.

[0026] Meanwhile, an arc-shaped baffle 17 is fixedly installed on the guide surface 7 at the lower end of the mixing hopper 3. The arc-shaped baffle 17 divides the guide surface 7 into an outer guide surface 18 and an inner guide surface 19. The outer guide surface 18 is distributed on the side of the arc-shaped baffle 17 close to the axis of the mixing hopper 3. The outer guide surface 18 is connected to the surface of the guide surface 7. The powder guided by the surface of the outer guide surface 18 can enter the surface of the guide surface 7. The inner guide surface 19 is distributed on the side of the arc-shaped baffle 17 away from the axis of the mixing hopper 3. The end of the inner guide surface 19 is separated by the arc-shaped baffle 17. Due to centrifugal force, the heavier and larger substances in the powder will be thrown into the inner guide surface 19 and transported along the inner guide surface 19 to the collection chamber 8 for collection. This achieves the purpose of separating the larger substances in the powder. The collection chamber 8 is a cavity formed by the arc-shaped baffle 17 and the inner wall of the mixing hopper 3. The powder entering the inner guide surface 19 is lighter and will eventually be sucked into the surface of the guide surface 7 and discharged.

[0027] It should be noted that a filter cotton 16 is fixedly attached to the lower surface of the upper baffle plate 14. The filter cotton 16 is used to block the powder from entering the air hole 15. The air hole 15 is used to allow air to circulate, so that the eddy current generated when the stirring plate 12 rotates can act on the bottom of the upper baffle plate 14. It will not be unable to act on the bottom of the upper baffle plate 14 because the bottom of the upper baffle plate 14 is completely sealed with the inner ring of the baffle ring 13.

[0028] Furthermore, the material pump is a vacuum material pump. The suction port of the vacuum material pump is connected to the discharge port of the mixing hopper 3, and the discharge port of the vacuum material pump corresponds to the bottle 6 on the packaging conveyor line 5. The selection of the material pump should be determined according to the properties of the powder and the conveying requirements. The vacuum material pump can provide stable suction to ensure that the powder can be smoothly conveyed from the mixing hopper 3 to the bottle 6 on the packaging conveyor line 5, realizing an automated filling process.
