Description

Technical Field

[0002] Pellets are spherical or quasi-spherical solid dosage forms with a smaller diameter. They can also be put into capsules, compressed into tablets, or made into other preparations. Pellets are a multi-unit oral dosage form. Usually, a single dose of the drug consists of dozens to hundreds of small pellets. They can be made into different types of pellets, such as sustained-release and enteric-coated pellets. Compared with granules or powders, pellets have better fluidity. When pellets are filled into capsules, no glidant is required. Compared with filling capsules with powders, the weight difference is small, and they are often used to prepare compound preparations.

Next, a slide plate 3 is installed on the mounting slide rail 2 to ensure that the slide plate 3 can slide smoothly on the mounting slide rail 2. The top of the slide plate 3 is used to install the supporting mechanism. The specific construction of the supporting mechanism is as follows: a supporting guide rail 4 is fixedly installed on the top of the slide plate 3, and the supporting guide rail 4 extends along the length direction of the slide plate 3. A movable guide frame 5 is slidably connected to the supporting guide rail 4, and the movable guide frame 5 is fixedly connected to the supporting guide rail 4 by two bolts to ensure its stability and adjustability. A connecting plate 9 is fixedly installed on the top of the movable guide frame 5, and a mounting ring 10 is fixedly installed on one side of the connecting plate 9 for the subsequent installation of the feeding mechanism. The feeding mechanism is installed on the mounting ring 10, which mainly includes a storage box 11. The storage box 11 passes through the mounting ring 10 and is fixedly connected to the mounting ring 10 to ensure the stability of the feeding. A discharge pipe 23 is fixedly installed at the bottom outlet position of the storage box 11 for discharging the pellets. A cover plate 12 is sealed and clamped at the top opening position of the storage box 11 to prevent the entry of foreign impurities. A plurality of lock plates 13 are fixedly installed at equal intervals on the top of the cover plate 12, and a plurality of lock buckles are installed at equal intervals on the top of the storage box 11. Each lock buckle consists of two rotating rods 14 and a locking rod 15. The two rotating rods 14 are rotatably connected to the top of the storage box 11, and the locking rod 15 is fixedly installed on the top of the two rotating rods 14 for clamping with the locking plates 13, thereby achieving stable positioning of the cover plate 12. In order to adjust the lateral position of the feeding mechanism, a mounting plate 6 is fixedly installed on one side of the mounting slide rail 2, and a screw 7 is rotatably connected to the mounting plate 6. A nut 8 is fixedly installed at the bottom of one side of the support rail 4, one end of the screw 7 passes through the support rail 4 and the nut 8 and is threadedly connected to the nut 8, and the other end is rotatably connected to the mounting rail 2. By rotating the screw 7 and utilizing the threaded transmission effect between the screw 7 and the nut 8, the support guide rail 4 and the entire feeding mechanism can be driven to move laterally to align the hopper of the micro-pill filling machine 1. The air supply mechanism is installed on the support mechanism, one side of which extends into the storage box 11 and is connected to the inner wall of the storage box 11, and is used to inject inert gas into the storage box 11 to protect the micro-pills from the external environment.

In addition, the pressure plate 17 is tightly slidably connected in the cover plate 12, and the push rod 18 is fixedly installed on the top of the pressure plate 17.

[0038] Example 2

[0039] refer to Figure 3 and Figure 7, improved on the basis of embodiment 1: a feeding mechanism of a capsule micro-pill filling device, which 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-pills, the gas supply mechanism is designed and installed in detail. First, a mounting frame 29 is fixedly installed on the top of the connecting plate 9, and the mounting frame 29 serves as a basis for supporting and fixing the exhaust assembly. On the mounting frame 29, an exhaust assembly is fixedly installed, and the core component of the assembly includes a power box 30, and the power box 30 is firmly fixed inside the mounting frame 29. In the power box 30, a driving motor 31 is installed, and the output shaft of the motor passes through the wall of the power box 30 and extends to the inside thereof, and a group of suction blades 33 are fixedly installed at the end of the output shaft. These suction blades 33 can rotate at high speed driven by the driving motor 31, thereby generating suction. In order to introduce external inert gas into the power box 30, an air receiving pipe 32 is fixedly installed on the inner wall of the bottom of one side of the power box 30. One end of the air connection pipe 32 extends to the outside of the power box 30, so as to facilitate connection with the external inert gas delivery pipe. When the external inert gas enters the power box 30 through the air connection pipe 32, the rotation of the suction blade 33 will suck these gases and guide them to the air delivery pipe 28. The bottom end of the air delivery pipe 28 extends to the inside of the power box 30 and is connected to the suction area of ​​the suction blade 33, ensuring that the inert gas can smoothly enter the air delivery pipe 28. An annular pipe 27 is fixedly installed at the other end of the air delivery pipe 28, and the annular pipe 27 is tightly sleeved on 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 annular pipe 27, and one end of these mounting pipes 26 passes through the wall of the storage box 11 and extends to the inside thereof. Inside the storage box 11, the ends of all the mounting pipes 26 are connected together and fixedly installed with an annular nozzle 21. The annular nozzle 21 is installed close to 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 liner tube 22 is fixedly installed at the bottom of the annular nozzle 21, which can guide the inert gas to diffuse to the central area of ​​the storage box 11, thereby achieving comprehensive protection of the micro-pellets. In actual use, the inert gas source is first connected to the gas connection pipe 32 through an external delivery pipe. Then the drive motor 31 is started, and the drive motor 31 drives the suction blade 33 to rotate, generating suction to suck the inert gas into the power box 30, and transporting it to the annular tube 27 through the gas delivery pipe 28. In the annular tube 27, the inert gas is evenly distributed to each installation tube 26, and finally sprayed into the storage box 11 through the annular nozzle 21 and the conical liner tube 22, achieving all-round protection of the micro-pellets.

[0040] However, as is well known to those skilled in the art, the working principles and wiring methods of the pressure sensor 20, stepper motor 24 and drive motor 31 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.
