Double-head Linear Defect-free Filling Machine

Keypack Intelligent Twin-Head Linear Filling Machine for Zero-Defect Powder Packaging

Keypack Intelligent Twin-Head Linear Filling Machine is a precision dual-head defect-free filler designed for high-accuracy powder packaging with guaranteed yield rates. It delivers 45–55 pcs/min throughput with dual weighing verification and no-bottle no-fill protection, ensuring every package meets target weight specifications. Ideal for milk powder filling, nutritional products, protein powder packaging, and pharmaceutical powder applications.

Product Overview

This advanced twin-head linear filling machine combines precision weighing technology with intelligent automation to achieve zero-defect filling performance. The system features dual weighing verification—coarse filling followed by precision top-up—ensuring each container receives the exact target weight without underfilling. With PLC control and touch screen operation, the Keypack Intelligent (kunbupack) Twin-Head Filler offers one-touch startup and requires minimal operator intervention once parameters are set.

The machine's modular design enables quick changeover between different container sizes by replacing only specific tooling components, while the main assembly remains universal. This high-precision filler incorporates automatic dust control to maintain a clean production environment and features sealed separation between the working surface and control panel for enhanced operator safety and equipment protection.

Key Features and Machine Characteristics

• Dual Weighing Verification for Perfect Yield Rate: Two-stage weighing feedback system ensures final product weight never falls below formula specification, dramatically improving good product rate and eliminating giveaway. The zero-defect powder filling system performs coarse filling, first weighing check, precision top-up, and final verification to guarantee target weight accuracy.
• No-Bottle No-Fill Detection System: Multiple detection points prevent operation without containers present—inlet detection prevents star wheel rotation when containers are absent, coarse filling detection ensures no activation without containers, and precision filling detection guarantees safe operation throughout the process. This intelligent protection enhances equipment safety and reduces material waste.
• Hygienic Design with Automatic Dust Control: Integrated filling dust extraction system maintains clean production environment, reduces powder waste, and protects operator health while meeting food safety and pharmaceutical standards. The enclosed structure prevents contamination and maintains environmental cleanliness during milk powder filling and pharmaceutical powder operations.
• High Versatility and Quick Changeover: Universal design accommodates multiple packaging materials with a single dual-head defect-free filler. Easy changeover requires only replacing specific tooling for different product dimensions while main components remain compatible across formats. This modular construction enables seamless integration within various production line configurations.
• Advanced PLC Control with Touch Screen Operation: High automation level with user-friendly touch screen interface enables intuitive parameter setting, real-time monitoring, and simplified maintenance. One-touch startup after initial setup reduces training requirements and operator intervention, delivering consistent high-precision filling performance.
• Sealed Safety Architecture: Working surface and control panel are sealed and isolated to protect operators and equipment. The enclosed structure maintains environmental cleanliness, prevents cross-contamination, and ensures compliance with hygienic design standards for nutritional products and protein powder packaging applications.
• Modular Construction for Line Integration: Compact modular design facilitates placement within various production line configurations, enabling seamless integration with upstream feeding systems and downstream capping, labeling, or case packing equipment for complete turnkey packaging solutions.
• Premium Aesthetic Design: Modern exterior design with elegant appearance suitable for high-standard production facilities, reflecting professional manufacturing quality and meeting contemporary facility requirements for food, pharmaceutical, and nutraceutical industries.
