Ensuring Efficiency and Accuracy: An Essential Guide to Capsule Filling Machine Accessories

In the pharmaceutical, health products, and cosmetics industries, capsule filling machines are crucial core equipment on production lines. Its operational stability, filling accuracy, and production efficiency directly determine the quality and cost of the final product. However, a high-performance capsule filling machine cannot do without the collaborative work of a series of precision components. The correct selection, use, and maintenance of these accessories are key to ensuring the continuity of your production and product consistency.

This article will provide you with a detailed introduction to the main accessories and their importance of capsule filling machines, helping you make more informed decisions.

1、 Why are accessories so important?

Although the accessories are small, their function is enormous. They are like the "joints" and "pulse" of a machine:

Ensure accuracy: Worn parts can lead to excessive differences in assembly quantity, resulting in product waste and non conformance.

Maintaining Efficiency: High quality accessories reduce downtime and improve overall equipment efficiency (OEE).

Ensure compatibility: Specialized accessories are required for different material characteristics (such as fluidity, density) and capsule models to achieve optimal results.

Extending the lifespan of the host: Regularly replacing vulnerable parts can avoid irreversible wear and tear on key components of the host.

2、 Detailed explanation of core accessories

The following are the most critical replaceable accessories in a standard capsule filling machine:

1. Measuring disk&filling rod

Function: This is the "heart" of the filling machine, directly responsible for accurately measuring and filling powders, particles, or pellets into the capsule body. The number and size of holes on the measuring disk determine the filling amount.

Material: High hardness and wear-resistant stainless steel (such as 304, 316L) or special alloy steel are usually used, and precision machining and polishing treatment are carried out to ensure no residue and wear resistance.

Focus: Different materials require measuring discs with different structures (such as single-layer, double-layer, with stopper rod, etc.). Worn measuring discs can lead to inaccurate dosage and cross contamination.

2. Module&Drum

Function: A precision mold used to accommodate and position capsule caps and bodies. The processing accuracy directly determines the quality of capsule stitching and the yield of finished products.

Material: High strength stainless steel or bronze alloy, with extremely high dimensional stability and wear resistance.

Focus: Strictly match according to the capsule model (such as 00 #, 0 #, 1 #). Module damage can lead to capsule failure, jamming, or appearance defects.

3. Lower Housing&Upper Housing

Function: Cooperate with the module to fix and separate the capsule cap and capsule body during the filling process.

Material: Wear resistant stainless steel.

Attention: Long term use may cause wear and tear, resulting in poor separation or inaccurate positioning of the capsules, which requires regular inspection and replacement.

4. Powder scraper&sealing strip

Function: The scraper is used to smooth out excess material on the surface of the measuring disc, ensuring consistent filling of each measuring hole. The sealing strip is used to prevent powder leakage and protect the moving parts inside the machine.

Material: food grade polyurethane (PU), PTFE or medical silicone, with excellent wear resistance and elasticity.

Focus: Belongs to high-frequency consumables. Hardened or worn powder scrapers can seriously affect filling accuracy, and damaged sealing strips can cause dust pollution and equipment wear.

5. Fork Spring&Pin

Function: The fork spring is used to reliably hold the capsule during workstation transitions, and the ejector pin is used to push out the capsule at specific workstations.

Material: Special spring steel, stainless steel.

Attention: Fatigue or breakage can cause capsule delivery failure, jamming or rupture, and inventory needs to be prepared for timely replacement.

6. Transmission system accessories

Including: gears, camshafts, bearings, conveyor belts, etc.

Function: Provide precise and reliable power transmission and motion trajectory for machines.

Focus: Using original or high-quality transmission components can ensure smooth operation, low noise, and long service life of the machine.
