The structure and principle of capsule filling machine

The structure and principle of capsule filling machine

The filling speed of the capsule filling machine is relatively fast, and the difference of the size of the capsule filling machine is small, and the powder capsule shell finishing, the capsule cap finishing and the capsule set are integrated, which is compact and convenient. In addition, the capsule filling machine has many advantages such as high speed, high efficiency, simple operation, convenient maintenance and low power consumption. It is the preferred capsule filling (filling) machine for pharmaceutical factories, health care products factories and hospital preparation rooms. 

Automatic capsule filling machine structure

The automatic capsule filling machine is composed of an empty capsule feeding device, a capsule dispensing device, a powder discharging device, a metering disk mechanism, a capsule filling and sealing mechanism, a main transmission mechanism in the box, and an electrical control system.

1. Empty capsule feeding device: consists of a hopper and a conveying pipeline, which mainly stores empty capsules and allows empty capsules to enter the capsule sub-assembly vertically one by one.

2. Capsule dispensing device: The empty capsule enters the selection fork of the dispensing device, and the selected fork will send down six capsules once and the rubber cap is on. At the same time, the vacuum separation system passes the capsule into the module and separates the body cap.

3. Powder feeding device: It consists of a powder bucket, a powder bucket screw, a blanking conveying pipe, etc., and mainly controls the stored powder under the action of the screw and the stirring into the measuring tray.

4. Metering disc mechanism: The metering disc specifications matched according to the capsule specifications and loading. The powder is compacted into a drug column by five fillings in an intermittently rotating metering tray and pushed into the capsule of the lower module.

5. Capsule filling and sealing mechanism: After pushing the capsule body under the capsule, the rubber cap of the upper and lower modules and the lower capsule push upward to make it buckle.

6. The main transmission mechanism in the box: the power required for the execution work is completed by the motor, the box type Fukaisen intermittent rotation mechanism, the gear pair, the deceleration, the cam pair and the chain transmission mechanism. At the same time, the variable frequency motor reaches the frequency conversion speed regulation function.

7. Electrical control system: The process elements of the filling of each capsule are controlled by the PLC system.

The principle of automatic capsule filling machine

The main working principle of the automatic capsule filling machine is that when the machine is running, the capsules in the capsule hopper will enter the first delivery fork of the dispensing device one by one. When the fork is moved down once, six capsules will be sent and the rubber cap will be on. In the first work, the vacuum separation system passes the capsule into the module while separating the body caps. When the turntable is intermittently rotated to the second work, the upper meter is quickly raised and moved inward. In the fifth working filling rod, the compacted medicine column is pushed into the capsule of the lower module, and the undivided capsule is in the eighth work. exclude. The upper and lower modules are put together in the tenth work, and the lower capsule body is pushed upward to make it buckle. On the eleventh working position, the finished capsule product is pushed out and collected. In the twelfth station, the vacuum cleaner cleans the module and then enters the next cycle. The drug column is compacted by five fillings in a metering disk that is intermittently rotated.
