1. What Is JTJ‑A Semi‑Auto Capsule Filling Machine
The JTJ‑A semi‑auto capsule filling machine is an upgraded semi‑automatic hard capsule filling machine designed for small‑to‑medium batch pharmaceutical, nutraceutical, health supplement and laboratory productiones.dmachin.... As a high‑end semi‑automatic capsule filler, it inherits mature capsule‑sowing structure from full‑automatic capsule filling equipment, integrating electromechanical‑pneumatic combined control, Siemens PLC programmable controller, touch‑screen HMI and frequency‑conversion stepless speed‑regulation system to replace labor‑intensive manual capsule filling.
Different from basic manual capsule filling tools or entry‑level semi‑automatic capsule filling units, the JTJ‑A semi‑auto capsule filling machine delivers stable capsule orienting, vacuum capsule cap‑body separation, auger‑driven powder filling, pneumatic flat‑mode capsule locking and finished capsule discharging with minimal manual intervention. Operators only need to feed empty capsules, load raw material and trigger foot‑switch locking. The finished product qualification rate can reach up to 98% for both locally‑made and imported standard hard capsules.
This pharmaceutical‑grade semi‑automatic capsule filling machine is suitable for filling non‑sticky, non‑wet powder and small granules into hard gelatin capsules or vegetarian HPMC capsules. It is widely deployed in small‑scale pharma workshops, health‑food manufacturers, contract packing facilities, pharmacy labs and university R&D centers for formula trial runs and pilot‑scale batch manufacturing
2. Core Working Principle of JTJ‑A Semi‑Auto Capsule Filling Machine
The workflow of the JTJ‑A semi‑automatic capsule filling machine for powder and small granules follows five core automated phases: capsule dispensing & orienting, vacuum separation, quantitative filling, pneumatic capsule locking and finished‑product output, managed by PLC logic and vacuum‑pump negative‑pressure system.
-
Capsule‑Sowing & U‑Turn Orientation Empty hard capsules are fed into the capsule hopper. The capsule‑sowing mechanism pushes rows of capsules into capsule combs. Guided by mechanical positioning components, capsules perform U‑turn movement, with capsule bodies facing downward and caps upward.
-
Vacuum‑Assisted Capsule Separation Powered by a 40 m³/h vacuum pump, negative airflow sucks capsule bodies down into lower mold cavities, while capsule caps are retained in upper mold holes. This vacuum separation design reduces friction and capsule damage compared with mechanical‑only separation on older‑generation semi‑automatic capsule filling equipment.
-
Quantitative Auger Filling Three independent frequency‑conversion motors drive the capsule‑dispensing unit, rotary turntable and powder‑feeding auger separately. Operators adjust feeding motor speed and turntable rotation cycles on the touch‑screen to match powder flowability. The auger forces powder or free‑flow small granules into separated empty capsules. PLC photoelectric counting monitors turntable cycles to control filling duration automatically.
-
Pneumatic Flat‑Mode Capsule Locking Filled capsules move to the locking station. Operators trigger the foot‑switch valve to activate the flat‑mode pneumatic locking mechanism. Pneumatic cylinders press capsule caps and bodies tightly together. The flat‑locking structure effectively avoids powder trembling and powder leakage during capsule closing, improving finished‑product quality.
-
Finished Capsule Discharge Locked complete capsules are ejected automatically into the collection box. Total output, capsule‑dispensing count and turntable cycle data are displayed and logged on the Siemens touch‑screen for production traceability. Safety interlock sensors stop relevant movements when safety protective doors are opened during operation.

5. Key Advantages of JTJ‑A Semi‑Auto Capsule Filling Machine
-
Upgraded Capsule‑Sowing Structure Derived from Full‑Automatic Machines Unlike traditional semi‑automatic capsule fillers, JTJ‑A adopts mature capsule‑dispensing design from high‑speed full‑automatic capsule filling machines, lowering capsule‑jamming rate and mechanical friction loss, extending service life of wearing spare parts such as capsule‑sowing combs and tubes.
-
Siemens PLC & Multi‑Language Touch‑Screen Operation All core control components adopt well‑known industrial brands. Operators set dispensing frequency, filling speed, turntable cycles and output coefficient directly on HMI. Real‑time fault‑diagnosis status page displays sensor status with green‑normal / red‑fault indicator lights, simplifying troubleshooting for maintenance technicians.
-
Flat‑Mode Pneumatic Capsule‑Locking Function Pneumatic flat‑press locking avoids powder shaking‑out during capsule closing, which is a common defect of old‑style mechanical locking semi‑automatic capsule filling machines. It improves capsule sealing performance and reduces material waste.
-
