Semi automatic capsule filling machineMainly used in industries such as pharmaceuticals and health products, filling materials such as powders and granules into hollow capsules. The process principle mainly includes steps such as capsule sorting and orientation, separation, filling, and locking. The following is an introduction for you:

Capsule sorting and orientation

Principle: The semi-automatic capsule filling machine has a dedicated capsule hopper, which contains a large number of disorganized hollow capsules. During machine operation, the capsules are continuously rolled and moved inside the hopper through vibration or rotating devices. In this process, utilizing the shape characteristics of the capsule itself, specific tracks and guiding devices are used to arrange the capsules in a certain direction, with the capsule cap facing up and the capsule body facing down, achieving the orientation of the capsule.

Function: To prepare for subsequent separation and filling operations, ensuring that each capsule can enter its corresponding working position in the correct posture and ensuring the smooth progress of the filling process.

Capsule separation

Principle: The sorted and oriented capsules will enter the separation mechanism. The separation mechanism usually consists of two modules, the upper and lower modules corresponding to the capsule cap and capsule body, respectively. By precise mechanical action, the upper module moves downwards to separate the capsule cap from the capsule body. Generally, the capsule cap is fixed to the upper module by vacuum adsorption or mechanical clamping, and then the capsule body is left in the lower module to achieve capsule separation.

Function: Separate the capsule body and capsule cap to fill the capsule body with materials separately, avoiding material filling into the capsule cap.

Material filling

Principle: The separated capsule body is transported to the filling station. There is a material warehouse in the filling mechanism, which contains the powder or granular materials that need to be filled. The main filling methods include gravity filling, metering filling, etc. Gravity filling is the use of the material's own gravity to allow the material to naturally fall into the capsule body; Measurement filling is achieved through measuring devices such as measuring disks, measuring rods, etc., which precisely control the amount of material filled into the capsule body each time, ensuring that the amount of material filled into each capsule is consistent.

Function: Accurately fill the separated capsule with a quantitative amount of material to ensure the effective dosage of drugs or health products.

Cleaning of residual powder

Principle: During the filling process, there may be a small amount of material residue around the filling station or at the edge of the capsule body. The residual powder cleaning device usually uses brushes, blowing air, and other methods to clean the surface and surrounding residual powder of the capsule to ensure the cleanliness and appearance quality of the capsule.

Function: To prevent residual powder from affecting the sealing and appearance of the capsule, while avoiding material waste.

Capsule locking

Principle: The capsule body filled with materials is moved to the locking station under the drive of the conveying device. At this point, the previously separated capsule caps are also transported to the corresponding positions. By using mechanical pressure or clamping devices, the upper and lower modules work together again to accurately fasten the capsule cap onto the capsule body, tightly combining the cap and body of the capsule to form a complete capsule.

Function: To make the filled capsule into a whole, prevent material leakage, and ensure the quality and stability of the capsule.

Finished product output

Principle: The locked capsules will be transported to the finished product collection device, and the capsules will be arranged in an orderly manner and output to the designated container through vibration, conveyor belt, etc., completing the entire filling process.

Function: Collect qualified capsule products for subsequent packaging and use.
