Keypack Intelligent Automatic Powder Weighing Equipment is designed for high-precision large bag filling with direct weighing measurement. It delivers ±0.1% accuracy for 10-50kg bags at 1-2 bags/min with dual screw feeding and servo-driven control. Ideal for flour packaging, pharmaceutical powder filling, and chemical powder applications requiring dust-free operation and GMP standard compliance.
Product Overview
The Keypack Intelligent (Kunbupack) Automatic Weighing Line for large bag powder packaging integrates direct weighing measurement, dual screw feeding mechanism, and servo-controlled lifting system into a semi-automatic vertical packaging solution. This dust-free powder filling equipment is engineered for free-flowing and poor-flowing materials including flour, cocoa powder, solid beverages, veterinary medicine, glucose, pharmaceutical powders, powdered additives, carbon powder, pesticides, dyes, and flavors.
Equipped with PLC touch screen control and load cell-based weighing feedback, this automatic bag packaging machine ensures stable filling accuracy while minimizing material waste and dust emission. The full stainless steel construction meets food-grade and pharmaceutical industry requirements, making it suitable for multi-material production environments.
Key Features and Machine Characteristics
1. High-Precision Automatic Weighing System
The GMP standard weighing machine utilizes load cell technology with weighing feedback control, automatically switching between fast filling and slow filling modes based on target weight. This design overcomes packaging weight variations caused by material density changes, ensuring consistent accuracy across different powder types.
2. Servo-Driven Dual Screw Feeding
Servo motor and servo drive control the dual screw mechanism, providing stable and precise powder dosing. The fixed screw installation structure maintains material properties during filling, suitable for ultra-fine powder to small granule materials. Interchangeable screw attachments allow adaptation to various material characteristics.
3. Dust-Free Powder Filling with Lifting System
The servo-controlled lifting platform features adjustable speed control, effectively reducing dust emission during the filling process. This dust-free powder packaging design improves working environment safety and material containment, particularly important for pharmaceutical and chemical applications.
4. PLC Touch Screen Control with Recipe Storage
The PLC touch screen control system offers intuitive operation with parameter setting, mode switching, and production monitoring capabilities. The automatic weighing line can store up to 10 product parameter recipes, enabling quick changeover between different materials and package sizes for high-speed packaging efficiency.
5. Full Stainless Steel Construction
The complete stainless steel structure ensures durability and compliance with food-grade and pharmaceutical industry standards. The combined or open-type transparent hopper design allows convenient cleaning and maintenance without tools, supporting GMP requirements and multi-product production.
6. Flexible Bag Feeding and Clamping System
The pneumatic bag clamping device mounts directly on the weighing unit for stable filling performance. This automatic bag packaging machine supports both bag feeding and container filling configurations, with optional clamping devices to accommodate various packaging formats.
