Description

Technical Field

[0001] This utility model relates to the field of powder pharmaceutical processing technology, and in particular to an adjustable metering continuous feeding device for powder pharmaceuticals. Background Technology

[0002] In industries such as pharmaceuticals, chemicals, and food processing, precise quantitative dispensing of powdered pharmaceuticals is a crucial step in ensuring product quality and production efficiency. Taking the pharmaceutical industry as an example, the accurate proportions of drug components directly affect efficacy and safety; in the chemical raw material processing field, the metering accuracy of powdered pharmaceuticals determines the stability of chemical reactions; and the quantitative addition of food additives is related to product quality and flavor consistency. With the increasing automation and intelligence of production, traditional powder dispensing devices, due to their low metering accuracy and inconvenient adjustment, can no longer meet the demands of modern industry for high-precision and high-efficiency production. Therefore, technological innovation is urgently needed to achieve precise control and flexible adjustment of the pharmaceutical dispensing process.

[0003] Existing powder feeding devices are mainly divided into three types: gravity type, screw type and vibration type. Gravity type feeding devices control the feeding amount by adjusting the hopper tilt angle and outlet size. Screw type feeding devices use a screw to push the powder and adjust the feeding speed by adjusting the motor speed. Vibration type feeding devices use the frequency of the vibrating plate to control the falling of the powder.

[0004] However, existing powder feeding devices generally suffer from the inability to precisely adjust the feeding rate and the difficulty in achieving continuous and stable feeding, which seriously restricts production efficiency and product quality. Traditional devices mostly use fixed openings or single speed control for feeding, making it difficult to flexibly adjust feeding parameters according to different production batches and different powder characteristics. In pharmaceutical production lines, insufficient drug ratio accuracy leads to fluctuations in drug content, requiring frequent rework and debugging. When feeding chemical raw materials, unstable feeding rates can cause material accumulation or ratio imbalance in the reaction vessel, increasing safety hazards. In addition, some devices are prone to feeding interruptions due to powder accumulation and adhesion during continuous operation. Therefore, an adjustable metering continuous feeding device for powders is proposed to solve the above problems. Utility Model Content

[0035] Reference Figures 1-4 An embodiment of this utility model provides: an adjustable metering continuous feeding device for powdered medicine, including a support frame 1, a hopper 2 fixedly connected to one side of the support frame 1, a conveying pipe 3 fixedly connected to the bottom of the hopper 2, a connecting frame 5 fixedly connected to one side of the hopper 2, a cylinder 6 fixedly connected to one side of the connecting frame 5, a slide 7 fixedly connected to the output end of the cylinder 6, a piston rod 9 fixedly connected to the bottom of the slide 7, a fixed pipe 8 fixedly connected to one side of the connecting frame 5, the piston rod 9 slidably connected inside the fixed pipe 8, the cylinder 6 pushes the slide 7 to move through the output end, the piston rod 9 at the bottom of the slide 7 slides along the inner wall of the fixed pipe 8, the fixed pipe 8 plays a guiding and limiting role, ensuring that the slide 7 remains stable during movement and avoiding shaking, a connecting frame 10 fixedly connected to the bottom end of the fixed pipe 8, a metering component is provided inside the connecting frame 10, and a feeding component is provided at the bottom of the connecting frame 10;

[0036] The metering component includes a hollow column 11, which is rotatably connected inside the connecting frame 10. The hollow column 11 has three material holes 12 arranged in a ring array inside. One end of the conveying pipe 3 is connected to the inside of the connecting frame 10. A fixed frame 4 is fixedly connected to the bottom of the hopper 2. A rotating block 13 is rotatably connected inside the fixed frame 4. A driving component is provided on one side of the rotating block 13. The driving component includes an electric push rod 14 and a connecting block 16. One side of the electric push rod 14 is fixedly connected to one side of the rotating block 13, and one side of the connecting block 16 is fixedly connected to the output end of the electric push rod 14. A support shaft 15 is fixedly connected to one end of the hollow column 11. The outer wall of the support shaft 15 is fixedly connected to the inside of the connecting block 16. The electric push rod 14 pushes the connecting block 16, connecting... The connecting block 16 drives the support shaft 15, causing the hollow column 11 to rotate within the connecting frame 10. By controlling the rotation angle of the hollow column 11, the connection state between the material hole 12 and the conveying pipe 3 can be adjusted. When the material hole 12 is aligned with the conveying pipe 3, the powdered medicine flows into the hollow column 11. Rotating the hollow column 11 causes the material hole 12 to be misaligned, thus pausing the feeding. This achieves precise control over the flow rate and the amount of medicine fed at one time. The feeding component includes a feeding pipe 17 and a feeding head 18. The feeding pipe 17 is located at the bottom of the connecting frame 10. The feeding head 18 is fixedly connected to one end of the feeding pipe 17. The feeding pipe 17 receives the powdered medicine after the hollow column 11 has been quantitatively dispensed. Under the action of gravity, the medicine flows out from the feeding head 18 through the feeding pipe 17, completing the feeding process.

[0037] Reference Figure 1 , Figure 5 and Figure 6 A support frame 19 is fixedly connected to the top of the support frame 1. A fixed disk 21 is fixedly connected inside the support frame 19. A motor 20 is fixedly connected inside the support frame 19. A drive wheel 22 is fixedly connected to the output end of the motor 20. The drive wheel 22 is rotatably connected to the bottom of the fixed disk 21. Multiple rotating shafts 23 are rotatably connected inside the fixed disk 21. Driven wheels 24 are fixedly connected to the outer walls of the multiple rotating shafts 23. The multiple driven wheels 24 mesh with the drive wheel 22. The motor 20 drives the drive wheel 22 to rotate. The drive wheel 22 meshes with the multiple driven wheels 24, causing the rotating shafts 23 to rotate, thereby causing the connecting rod 25 to rotate around the rotating shafts 23. Multiple connecting rods 25 retract towards the center during rotation, which can clamp and fix the container placed on the fixed plate 21. The top of multiple rotating shafts 23 are fixedly connected to connecting rods 25, and the top of one side of multiple connecting rods 25 is rotatably connected to positioning posts 26, which can adaptively fit the surface of containers of different shapes and sizes, realize the rapid and stable fixation of containers of different specifications, and ensure that the position of the container does not shift during the feeding process.

[0038] Working Principle: When using this adjustable metering continuous feeding device for powdered medicine, the powdered medicine is first stored in the hopper 2. The bottom of the hopper 2 is connected to the conveying pipe 3. The medicine flows from the hopper 2 into the conveying pipe 3 due to gravity and the structural design of the hopper, and is then conveyed into the connecting frame 10 to prepare for subsequent quantitative feeding. The output end of the electric push rod 14 pushes the connecting block 16, which drives the support shaft 15, causing the hollow column 11 to rotate within the connecting frame 10. The hollow column 11 has three material holes 12 arranged in a ring array inside. By rotating the hollow column 11, the relative position of the material holes 12 and the conveying pipe 3 can be changed. When the hollow column 11 rotates to a specific position, the material holes 12 are connected to the conveying pipe 3, and a certain amount of powdered medicine enters the hollow column 11 through the material holes 12. By controlling the rotation angle and dwell time of the hollow column 11, the dosage of powder entering the hollow column 11 can be adjusted to achieve quantitative control. After quantitative control, the powder flows from the hollow column 11 into the feed pipe 17 under the action of gravity, and then flows out through the feed head 18. At the same time, the output end of the cylinder 6 drives the slide 7 to move, and the piston rod 9 at the bottom of the slide 7 slides in the fixed tube 8 to ensure the accuracy and stability of the feed.

[0039] When it is necessary to fix the container, first place the container on the fixing plate 21, then start the motor 20. Its output end drives the drive wheel 22 to rotate. The drive wheel 22 meshes with multiple driven wheels 24 in the fixing plate 21, so that the driven wheels 24 drive the rotating shaft 23 and the connecting rod 25 to rotate. The multiple connecting rods 25 are subjected to force and move towards the center above the fixing plate 21, thereby effectively fixing the container, thus achieving the effect of quickly fixing containers of different sizes.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
