A drug filling mechanism for pharmaceutical manufacturing

Abstract

This application relates to the field of pharmaceutical technology and discloses a drug filling mechanism for pharmaceutical manufacturing, including a motor, a telescopic rod, and an air pump. The output shaft of the motor is fixedly connected to a metering disc, and the upper surface of the metering disc has equidistantly arranged die holes. This drug filling mechanism for pharmaceutical manufacturing, through the inclusion of a telescopic rod, a hollow component, an air guide tube, and a flexible tube, rotates the metering disc via the motor, moving the die holes to a designated position. Activating the telescopic rod causes the mounting plate to lower a push rod and mounting rod. The push rod inputs the drug powder from the corresponding die hole into the capsule body below. At this time, the air guide tube enters the corresponding die hole, and the air pump, flexible tube, and hollow component allow airflow to exit through the air guide tube, blowing out any residual drug powder from the die holes. This prevents drug powder from adhering to the die holes of the metering disc, thus preventing any impact on filling accuracy. By setting a conical block on the inner wall of the mounting shell, the drug powder can automatically flow to the corresponding die hole, improving drug powder flowability.

Description

Technical Field

[0001] This application relates to the field of pharmaceutical technology, specifically to a drug filling mechanism for pharmaceutical manufacturing. Background Technology

[0002] Capsule packaging for pharmaceuticals has long been widely used by pharmaceutical companies both domestically and internationally due to its unique advantages in odor isolation and sustained release. Existing capsule filling mainly utilizes a metering disc filling mechanism with cylindrical metering holes to press powder into the die holes sequentially and evenly at different workstations, and then pushes the metering powder column into the capsule body to complete the filling.

[0003] However, it has been found that the existing drug filling mechanism is not suitable for highly viscous drug powders, as the powder will stick to the metering disc orifice, reducing the filling accuracy. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a drug filling mechanism for pharmaceutical manufacturing, which has the advantages of preventing drug powder from adhering to the die holes of the metering disc and preventing it from affecting the filling accuracy. This solves the problem that highly viscous drug powder is prone to sticking to the die holes of the metering disc, reducing the filling accuracy.

[0005] To achieve the above objectives, this application provides the following technical solution: a drug filling mechanism for pharmaceutical manufacturing, comprising a motor, a telescopic rod, and an air pump. The output shaft of the motor is fixedly connected to a metering disc, and the upper surface of the metering disc has equidistantly arranged die holes. The output end of the telescopic rod is fixedly connected to a mounting plate, and the bottom surface of the mounting plate is fixedly connected to equidistantly arranged push rods and mounting rods. The bottom end of the mounting rod is fixedly connected to a hollow component, and the bottom surface of the hollow component is fixedly connected to equidistantly arranged air guide tubes. The output end of the air pump is fixedly installed with a flexible hose, and the other end of the flexible hose is fixedly connected to the outer surface of the hollow component.

[0006] To prevent powder from adhering to the die orifices and affecting filling accuracy, the above solution uses a motor to rotate the metering disc, which in turn drives the die orifices. During filling, a telescopic rod lowers the mounting plate, which in turn lowers the push rod and mounting rod on the bottom surface. This push rod then pushes the powder down into the capsule below. The used die orifices are located below the mounting rod. When the push rod pushes the powder to fill, the mounting rod lowers the hollow component and air guide tube at the bottom. The air guide tube enters the corresponding die orifice, and airflow enters the hollow component through an air pump and hose. Through the air holes on the surface of the air guide tube, the airflow blows towards the corresponding die orifice, blowing off the powder adhering to the inner wall of the die orifice. This prevents powder from adhering to the die orifices of the metering disc and thus avoids affecting filling accuracy.

[0007] Furthermore, a fixing plate is fixedly connected to the outer surface of the mounting rod, and two guide rods are slidably connected to the inner wall of the fixing plate.

[0008] The above scheme involves installing a fixing plate on the outer surface of the mounting rod to form a fixed connection, thereby achieving the installation of the fixing plate, and installing a guide rod on the inner wall of the fixing plate to form a sliding connection, thereby achieving the limitation of the guide rod.

[0009] Furthermore, a protective shell is provided below the fixing plate, and the bottom end of each guide rod is fixedly connected to the upper surface of the protective shell.

[0010] The above solution involves installing the protective shell below the fixed plate and connecting the bottom end of the guide rod to the upper surface of the protective shell. The connection between the guide rod and the fixed plate enables the protective shell to be positioned.

[0011] Furthermore, two springs are fixedly connected to the upper surface of the protective shell, and the top of each spring is fixedly connected to the bottom surface of the fixing plate.

[0012] The above solution involves installing a spring on the upper surface of the protective shell as a fixed connection, and connecting the top of the spring to the bottom surface of the fixing plate as a fixed connection. The spring can hold the protective shell in place, and the protective shell can prevent the powder blown up during cleaning of the mold hole from escaping.

[0013] Furthermore, a fixing ring is fixedly connected to the bottom surface of the telescopic rod, a mounting bracket is fixedly connected to the inner wall of the fixing ring, and a storage tank is fixedly connected to the inner wall of the mounting bracket.

[0014] The above scheme involves installing a fixing ring on the bottom of the telescopic rod for a fixed connection, and installing a mounting bracket on the inner wall of the fixing ring to support and limit the telescopic rod. The storage tank is installed on the inner wall of the mounting bracket for a fixed connection. The storage tank is installed through the mounting bracket and is used to store the medicine powder.

[0015] Furthermore, a fixing frame is fixedly connected to the inner wall of the storage tank, and a motor is fixedly connected to the inner wall of the fixing frame.

[0016] The above scheme involves installing the fixing frame on the inner wall of the storage tank as a fixed connection, and installing the second motor on the inner wall of the fixing frame as a fixed connection, thereby limiting the movement of the second motor.

[0017] Furthermore, the output shaft of the second motor is fixedly connected to a fixing rod, and an auger is fixedly connected to the outer surface of the fixing rod.

[0018] The above scheme involves installing a fixed rod on the output shaft of motor two, setting it as a fixed connection. Motor two enables the fixed rod to rotate. An auger is installed on the outer surface of the fixed rod, setting it as a fixed connection. When motor two drives the fixed rod to rotate, the auger can rotate, allowing the powder to be transferred.

[0019] Furthermore, a mounting shell is fixedly connected to the bottom surface of the mounting bracket, a conical block is fixedly connected to the inner wall of the mounting shell, and the bottom surface of the mounting shell is fixedly connected to the outer surface of the motor.

[0020] The above method involves installing the mounting shell on the bottom surface of the mounting frame and installing the conical block on the inner wall of the mounting shell. The conical block allows the powder to flow to the corresponding mold hole position. The surface of motor one is fixed to the mounting shell by connecting ribs, thus realizing the installation of motor one.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This is a drug filling mechanism for pharmaceutical manufacturing. It incorporates components such as a telescopic rod, hollow parts, an air guide tube, and a flexible hose. A motor rotates the metering disc, moving the die to a designated position. Activating the telescopic rod causes the mounting plate to lower a push rod and mounting rod. The push rod feeds the drug powder from the corresponding die into the capsule below. At this point, the air guide tube enters the corresponding die, and an air pump, flexible hose, and hollow parts allow airflow to exit through the air guide tube, blowing out any residual drug powder from the die. This prevents drug powder from adhering to the die of the metering disc, thus ensuring accurate filling. A conical block on the inner wall of the mounting shell allows the drug powder to flow automatically to the corresponding die, improving powder flowability. Attached Figure Description

[0033] This embodiment describes a drug filling mechanism for pharmaceutical manufacturing. It includes components such as a telescopic rod 4, a hollow component 8, an air guide tube 9, and a flexible tube 11. A motor 1 rotates the metering disc 2, moving the die hole 3 to a designated position. Activating the telescopic rod 4 causes the mounting plate 5 to lower the push rod 6 and mounting rod 7. The push rod 6 inputs the drug powder from the corresponding die hole 3 into the capsule below. At this time, the air guide tube 9 enters the corresponding die hole 3. An air pump 10, flexible tube 11, and hollow component 8 allow airflow to exit through the air guide tube 9, blowing out any residual drug powder from the die hole 3. This prevents drug powder from adhering to the die hole 3 of the metering disc 2, thus preventing any impact on filling accuracy. A conical block 24 is provided on the inner wall of the mounting shell 23, allowing the drug powder to automatically flow to the corresponding die hole 3, improving drug powder flowability.

[0034] It should be noted that the telescopic rod 4 is electrically telescopic, with fast response speed and high accuracy. When the powder is filled into the die hole 3, the motor 1 drives the metering disk 2 to rotate, so that the corresponding die hole 3 can correspond to the capsule body. The powder is pushed into the capsule body below by the push rod 6. The mounting shell 23 is also equipped with multiple sets of push rods 6. Driven by the telescopic rod 4 inside the mounting shell 23, the die hole 3 is compacted inside the mounting shell 23 by multiple sets of push rods 6, so that the powder can be compacted.

[0035] The working principle of the above embodiments is as follows: Motor 1 drives the metering disc 2 to rotate. The telescopic rod 4 and push rod 6 inside the mounting shell 23 compact the powder inside the die hole 3 until the corresponding die hole 3 aligns with the capsule body. Then, the telescopic rod 4 on the outside is activated, causing the mounting plate 5 to drive the push rod 6 and mounting rod 7 to descend. The push rod 6 inputs the powder inside the corresponding die hole 3 into the capsule body below. At this time, the air guide pipe 9 enters the corresponding die hole 3. The air pump 10, hose 11 and hollow part 8 allow the airflow to be discharged through the air guide pipe 9, blowing out the powder remaining inside the die hole 3. This prevents the powder from adhering to the die hole 3 of the metering disc 2, thus preventing it from affecting the filling accuracy. The spring 14 and protective shell 15 prevent the powder from spreading and causing dust. Motor 20 rotates the fixed rod 21, which in turn rotates the auger 22, allowing the powder inside the storage tank 18 to fall onto the surface of the conical block 24. By setting the conical block 24 on the inner wall of the mounting shell 23, the powder can automatically flow to the corresponding die hole 3, improving the powder flowability.
