Product Overview
The Keypack Intelligent (Kunbupack) KL8-420 Pre-made Bag Filling Machine is an 8-station automatic pre-formed bag packager featuring advanced weighing technology and dust-proof design. This cup filling weighing machine integrates seamlessly with multi-head weighers to form complete automated packaging lines for wide-format bags ranging from 300-420mm in width. The machine supports stand-up pouches, handheld bags, four-side seal bags, three-side seal bags, paper bags, and composite bags, making it a versatile solution for food packaging machinery and chemical packaging line applications.
Equipped with variable frequency speed control and automatic bag width adjustment via hand crank, the KL8-420 automatic pre-formed bag packager offers flexible operation for large-capacity packaging from 10g to 4000g. The oil-free vacuum pump system with automatic bag feeding eliminates environmental pollution while maintaining high packaging efficiency. All material contact parts are manufactured from 304 stainless steel, ensuring compliance with food hygiene standards and suitability for snack packaging equipment and pet food packaging machine applications.
This pre-made bag filling machine can be configured with vacuum feeding conveyors, screw dosing machines, horizontal screw conveyors, and screw feeding conveyors to create fully automated powder and granule packaging production lines for agricultural product packing, pet food, and chemical granules applications.
Key Features and Machine Characteristics
1. User-Friendly PLC Control System
The automatic pre-formed bag packager features PLC control with HMI interface, enabling operators to monitor and adjust packaging parameters in real-time. This servo drive system enhances operational efficiency and reduces training time for new operators in food packaging machinery and snack packaging equipment applications.
2. Variable Frequency Speed Control
Equipped with variable frequency drive technology, the volumetric cup filling machine allows speed adjustment within specified ranges to match different material characteristics and production requirements, optimizing throughput for granules, powder, coffee beans, and pet food applications.
3. Convenient Bag Width Adjustment for Wide Format Bags
The automatic bag width adjustment system uses a hand crank mechanism, enabling quick changeover between different bag sizes from 300-420mm without tools. This feature is particularly valuable for manufacturers packaging large-format products on the same cup filling weighing machine, supporting diverse applications from bulk milk powder to pet food packaging.
4. Oil-Free Vacuum Pump with Automatic Bag Feeding
The oil-free vacuum pump system with automatic bag feeding eliminates the risk of oil contamination and environmental pollution, making this pet food packaging machine suitable for sensitive applications in food packaging machinery, snack packaging equipment, and agricultural product packing.
5. Food-Grade Stainless Steel Construction
All material contact parts are manufactured from 304 stainless steel, meeting food hygiene standards and ensuring product safety for milk powder, pet food, coffee beans, snacks, seeds, and grains. This construction also provides corrosion resistance for chemical packaging line operations handling chemical granules.
6. Integrated Automation Capability with Dust-proof Design
The KL8-420 pre-made bag filling machine features comprehensive dust-proof design and can be integrated with vacuum feeding conveyors, screw dosing machines, horizontal screw conveyors, and multi-head weighers to create complete automated packaging lines. This modular design supports diverse applications across food packaging machinery, chemical packaging lines, and agricultural product packing systems.
