Automatic Powder Filling Production Line | Bottle Unscrambler, Servo Auger Filling, Vacuum Feeding & Can Sealing System
Share to:
This automatic powder filling production line is designed for efficient and dust-free bottle packaging of powder materials. The complete system mainly consists of a bottle unscrambler, vacuum powder feeder, servo auger powder filling machine, dust collection device, automatic capping/sealing machine, and bottle arranging conveyor system. The vacuum feeder automatically transfers powder into the hopper without dust leakage, while the negative-pressure dust collection structure improves filling cleanliness. The line is suitable for continuous automatic filling and sealing of various powder products with high precision and stable production performance.
Machine Overview and Functional Description
The automatic powder bottle filling line is an integrated packaging solution specially developed for powder filling, bottle conveying, can sealing, and automated production management. The system combines bottle unscrambling, vacuum powder feeding, servo auger filling, dust extraction, and rotary can sealing into one continuous production process.
The bottle unscrambler is suitable for automatic sorting and conveying of round plastic bottles, square bottles, and glass containers. It can be directly connected with the filling and sealing equipment to achieve stable bottle transportation and improve overall production efficiency. The conveying speed is adjustable from 30–200 bottles per minute according to production requirements.
The powder filling machine adopts a full stainless steel structure with a transparent detachable hopper for convenient cleaning and maintenance. The servo-driven auger dosing system provides accurate and stable powder filling performance. The PLC control system with touch-screen HMI allows operators to easily adjust parameters and store up to 10 product recipes for quick product switching.
The machine is equipped with weighing feedback density tracking technology, which automatically compensates for material density variations to maintain filling accuracy. By replacing different auger screws, the system can handle ultra-fine powders, granules, and free-flowing materials.
The integrated vacuum feeder automatically transfers powder into the hopper through sealed negative-pressure conveying, reducing manual labor and preventing airborne dust contamination.
The rotary can sealing machine adopts a four-roller double-seaming structure with balanced sealing pressure, ensuring reliable sealing quality for PET, metal, aluminum, and paper cans. During the sealing process, the container remains stationary while the sealing rollers rotate, making the system especially suitable for fragile containers and high-speed continuous production.

Structural Design and Working Principle
1. PLC Touch Screen Control System
The intelligent PLC control system with touch-screen interface enables easy operation and real-time parameter adjustment. Operators can store multiple production recipes, monitor machine status, and quickly switch between different product specifications with improved production efficiency.
2. Vacuum Powder Feeding System
The vacuum feeder adopts sealed negative-pressure conveying technology to automatically transfer powder materials into the hopper. The system effectively reduces airborne dust, minimizes manual handling, and automatically triggers feeding when the hopper material level becomes low.
3. Dust Collection Device
The filling station is equipped with a negative-pressure dust extraction system that captures floating powder during filling operations. This structure helps maintain a cleaner production environment while reducing material waste and improving operator safety.
4. Rotary Can Sealing Machine
The rotary sealing system adopts a four-roller double-seaming structure for stable and high-speed sealing performance. The container remains stationary during sealing, making the machine suitable for fragile bottles, lightweight cans, and continuous automated production lines.
