It delivers 8-80 bags/min at 10-4000g filling range with combination weigher precision, servo control, and PLC touch screen operation. Ideal for milk powder packaging, pharmaceutical powder filling, and chemical powder applications requiring food-grade 304 stainless steel construction.
Product Overview
The Keypack Intelligent (Kunbupack) Premade Bag Filling and Sealing Machine integrates multi-head weigher technology, automatic bag feeding mechanism, and oil-free vacuum sealing system into a complete powder packaging solution. This premade pouch fill and seal machine is available in five models (KG8-200, KG8-260, KG8-300, KG8-420, KG10-200) with 8-10 stations, offering flexible bag size ranges and filling capacities for diverse powder packaging requirements.
Equipped with high accuracy weighing, dust-proof design, and frequency conversion speed control, this automatic powder bag filling machine handles free-flowing and poor-flowing materials including milk powder, protein powder, spice powder, flour, seasoning powder, instant drink powder, pharmaceutical powders, detergent powder, and chemical powders. The PLC control system with touchscreen HMI enables intuitive operation, while the 304 stainless steel material contact parts ensure compliance with food hygiene standards and pharmaceutical industry requirements.
Key Features and Machine Characteristics
1. Multi-Head Weigher with High Accuracy Weighing
The combination weigher system delivers precise powder dosing through intelligent weight combination algorithms. This weighing type bag filler ensures consistent filling accuracy across different powder densities and flow characteristics, reducing material waste and maintaining package weight consistency for milk powder, protein powder, and pharmaceutical powder applications.
2. PLC Control with Frequency Conversion Speed Adjustment
The PLC touch screen control system provides intuitive operation with real-time production monitoring and parameter adjustment capabilities. The frequency conversion speed control allows operators to adjust packaging speed within the specified range based on material characteristics and production requirements, optimizing throughput for food powder packaging and chemical powder packaging operations.
3. Automatic Bag Width Adjustment with Servo Control
The servo-controlled bag width adjustment mechanism enables quick changeover between different bag sizes through a simple hand crank operation. This premade pouch packing machine feature reduces setup time and improves production flexibility when switching between different product formats or package sizes in dairy powder packaging equipment applications.
4. Oil-Free Vacuum Pump with Dust-Proof Design
The oil-free vacuum sealing system eliminates environmental contamination risks while providing reliable sealing performance. Combined with the dust-proof design, this pharmaceutical powder filler maintains clean operation and protects sensitive materials from contamination during the filling and sealing process, particularly important for food and pharmaceutical applications.
5. Food-Grade 304 Stainless Steel Construction
All material contact parts are manufactured from 304 stainless steel, meeting food hygiene standards and pharmaceutical industry requirements. This pre-made bag powder packing machine construction ensures product safety, facilitates cleaning and sanitation, and provides long-term durability in demanding production environments.
6. Automated Powder Packaging Line Integration
This automatic powder bag filling machine can integrate with vacuum feeding conveyors, auger fillers, screw dosing machines, horizontal screw conveyors, and screw feeding systems to form complete automated powder packaging production lines. The modular design enables seamless integration with upstream material handling and downstream case packing equipment.
