Featuring a linear positioning structure with servo-driven control, the machine delivers stable output, precise filling accuracy, and strong adaptability to different container types. With GMP-compliant stainless steel construction and seamless integration capability into automated packaging lines, the Keypack Intelligent linear filling machine is well suited for food packaging, pharmaceutical packaging, and chemical packaging applications requiring reliable granule filling performance.

Key Features and Machine Characteristics

Linear Positioning Filling Structure

The Keypack Intelligent Linear Positioning Filling Machine adopts a linear single-station design, enabling orderly and stable filling operations. Depending on the model and material characteristics, the filling speed reaches 10–25 cans per minute, making it compatible with various automated production lines for granular products.

High-precision Servo Positioning Control

The machine utilizes a servo motor drive combined with photoelectric sensors to achieve accurate container positioning during filling. This precision filling system ensures a filling accuracy error of ≤ ±0.5%, effectively minimizing material waste and maintaining consistent filling results for granules, tablets, capsules, and similar products.

Automation and Production Line Integration

Designed for automated packaging environments, the Keypack Intelligent linear filling machine can be linked with upstream and downstream equipment such as can washing, drying, sealing, and labeling systems. This integration capability supports fully automated and unmanned operation across the entire filling and packaging process.

Strong Material and Container Adaptability

The equipment supports a wide range of granular materials, including food granules, pharmaceutical solids, and industrial particles. It allows quick changeover between round, square, and irregular containers, providing flexibility for multi-product and multi-format production requirements.
