Structure and principle of fully automatic capsule filling machine
Date: 2025-12-23Read: 6
The fully automatic capsule filling machine is the core equipment for producing capsule preparations in the pharmaceutical industry. Through intelligent mechanical design, it realizes the full process automation from capsule separation, powder measurement to packaging and fastening. Below, I will outline its structural composition and working principle for you.
1、 Structural composition
1. Empty Capsule Processing System
Empty capsule feeding device: Store and transport empty capsules one by one through a hopper and conveying pipeline.
Capsule dispensing device: Push 6 capsules each time, with the cap facing upwards, and use a vacuum separation system to separate the capsule body and cap.
Vacuum separation system: utilizing the principle of vacuum adsorption to achieve precise positioning of the capsule and cap.
2. Powder processing system
Powder feeding device: including powder hopper, screw and conveying pipe, responsible for mixing and conveying powder.
• Measuring disk mechanism: Automatically match the powder according to the size of the capsule. The powder needs to be filled and compacted 5 times to form a drug column before being pushed into the capsule.
Forced feeding device: Ensure accurate measurement of materials with poor fluidity.
3. Packaging and Power System
Capsule filling and sealing mechanism: Push the drug column into the capsule body and fasten the rubber cap.
Main transmission mechanism: powered by a motor and gear set, supporting variable frequency speed regulation.
PLC electrical control system: monitoring parameters through touch panel, supporting both fully automatic and jog modes.
4. Other auxiliary systems
Automatic lubrication system: effectively reduces equipment wear and tear.
Static elimination device: reduces dust pollution.
Cleaning and vacuuming mechanism: Remove powder and damaged capsule skin from the holes on the upper and lower capsule plates.
2、 Working principle
The working principle and process of the fully automatic capsule filling machine are as follows:
• Empty capsule supply: Remove cluttered hollow capsules from the capsule storage bucket.
• Arrangement: Through the directional arrangement device, all capsules are arranged in the open state of the capsule cover and fall into the capsule plate holes on the main working plate.
Correction direction: Ensure that the direction of the cap body is consistent.
• Cap separation: By utilizing the slight differences in the holes on the capsule plate and the vacuum force, the capsule body falls into the holes on the lower capsule plate.
• Drug filling: Fill the drug into the capsule body of the lower capsule plate through template measurement or intubation measurement.
• Waste removal: Unscented empty capsules are removed from the upper capsule plate so that they do not mix with charged capsules.
• Finished product discharge: Close capsules are discharged from the upper and lower capsule plate holes.
Cleaning: Use a dust collection system to remove powder and damaged capsule skin from the holes on the upper and lower capsule plates.
3、 Application scenarios
The fully automatic capsule filling machine is mainly suitable for automatic filling of powdered, granular or small pieces of materials, and meets the requirements of GMP standards. Its modular design combines precision and economic practicality, and maintenance requires regular lubrication of cam rollers and cleaning of powder contacting parts.
