[0038] Example 2
[0039] Reference Figure 3 and Figure 7On the basis of Embodiment One, an improved feeding mechanism of a capsule micro-pellet filling device is applied to the field of pharmaceutical machinery technology. In order to achieve uniform delivery of inert gas into the storage box to protect the micro-pellets, the gas supply mechanism is designed and installed in detail. First, a mounting bracket 29 is fixedly installed on the top of the connecting plate 9, which serves as the basis for supporting and fixing the air extraction assembly. On the mounting bracket 29, an air extraction assembly is fixedly installed, and the core components of the assembly include a power box 30, which is firmly fixed inside the mounting bracket 29. Inside the power box 30, a drive motor 31 is installed, and the output shaft of the motor extends through the wall of the power box 30 and into its interior. The end of the output shaft is fixedly installed with a set of air suction blades 33. These air suction blades 33 can rotate at high speed under the drive of the drive motor 31, thereby generating suction. In order to introduce external inert gas into the power box 30, a gas connection pipe 32 is fixedly installed on the inner wall of the bottom of one side of the power box 30. One end of the gas connection pipe 32 extends to the outside of the power box 30, facilitating connection with the external inert gas delivery pipe. When the external inert gas enters the power box 30 through the gas connection pipe 32, the rotation of the air suction blades 33 will suck these gases into and direct them to the gas delivery pipe 28. The bottom end of the gas delivery pipe 28 extends into the power box 30 and communicates with the air suction area of the air suction blades 33, ensuring that the inert gas can smoothly enter the gas delivery pipe 28. The other end of the gas delivery pipe 28 is fixedly installed with a ring-shaped pipe 27, which tightly fits around the outside of the storage box 11. A plurality of mounting pipes 26 are fixedly installed at equal intervals on the inner wall of the ring-shaped pipe 27, and one end of each mounting pipe 26 extends through the wall of the storage box 11 and into its interior. Inside the storage box 11, the ends of all the mounting pipes 26 are collectively connected and fixedly installed with a ring-shaped nozzle 21. The ring-shaped nozzle 21 is installed tightly against the inner wall of the storage box 11 to ensure that the inert gas can be evenly distributed inside the storage box 11. In order to further optimize the distribution effect of the inert gas, a conical lining pipe 22 is fixedly installed at the bottom of the ring-shaped nozzle 21, which can guide the inert gas to diffuse towards the central area of the storage box 11, thereby achieving comprehensive protection of the micro-pellets. In actual use, first connect the inert gas source to the gas connection pipe 32 through the external delivery pipe. Then start the drive motor 31, which drives the air suction blades 33 to rotate, generating suction to suck the inert gas into the power box 30 and deliver it to the ring-shaped pipe 27 through the gas delivery pipe 28. In the ring-shaped pipe 27, the inert gas is evenly distributed into each mounting pipe 26 and finally sprayed into the storage box 11 through the ring-shaped nozzle 21 and the conical lining pipe 22, achieving comprehensive protection of the micro-pellets.
[0040] However, as known to those skilled in the art, the working principles and wiring methods of the pressure sensor 20, the stepping motor 24 and the driving motor 31 are common, which all belong to conventional means or common general knowledge, and thus will not be described here again, and those skilled in the art can make any selection according to their needs or convenience.
[0041] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacements or changes within the technical range disclosed by the present application according to the technical solutions and the inventive concept of the present application, which should be covered within the protection scope of the present application.
