Product Introduction
The Automatic Vertical Granule/Powder Packaging Machine is a high-speed VFFS (Vertical Form Fill Seal) system engineered for accurate micro-dosing and consistent three-side sealing of small-dose granules such as disinfection granules, as well as compatible free-flow fine powders and granulated blends. Driven by an Inovance PLC and 7-inch color HMI, the machine integrates intelligent film feeding, Inovance servo bag pulling, pneumatic swing-cup metering, and a reinforced servo-controlled heat-sealing module to deliver stable output, uniform pouch appearance, and repeatable sealing strength across long production runs. With GMP-oriented structural design, corrosion-resistant material-contact components, and a clean, protected electrical cabinet, it is built for hygienic workshops that require dependable performance, fast adjustment, and controlled process parameters.
Product Features
Intelligent Control for Stable Production
The Inovance HMI + PLC platform provides centralized control, real-time status monitoring, and fault alarms with self-diagnosis to shorten troubleshooting time and reduce unplanned downtime. A 4-channel PID temperature control module ensures precise and stable heat management, with parameters easily set and displayed on-screen for quick verification during start-up and changeover.
Accurate Bag Length Tracking & Repeatable Dosing
Inovance servo-driven film pulling delivers precise bag-length control and smooth operation at high speed. Operators can switch between color-mark tracking and fixed-length mode directly on the touch screen, supporting printed films and standard rolls with equal stability. The pneumatic double swing measuring cup system is synchronized with the main unit for consistent feeding rhythm, helping maintain dosing repeatability across different speeds and material flow characteristics.
Reinforced Three-Side Sealing with Clear Texture
The strengthened heat-sealing assembly uses servo control to achieve low-noise operation, stable pressure, and clear sealing patterns. Optimized for composite aluminum film, the machine produces uniform transverse and longitudinal seals with adjustable sealing width, helping improve package integrity and leakage resistance for demanding products.
Fast Changeover and Convenient Mechanical Adjustment
An independent rotating cutter simplifies bag-length changes and cutter position adjustment. The metering unit adopts a handwheel lead-screw mechanism with a dial scale, enabling quick, repeatable settings for small-dose production. Measuring range conversion is supported by changing the measuring-cup accessory, allowing flexible adaptation to multiple gram weights.
GMP-Oriented, Corrosion-Resistant Construction
The exterior is built with 304 stainless steel and anti-corrosion surface treatment for durability in challenging environments. Product-contact parts adopt food-grade plastic and 316 stainless steel to enhance corrosion resistance and hygiene. The electrical cabinet is designed with a compressed-air ventilation structure to improve internal cleanliness and operational stability. Key electrical components utilize Schneider or OMRON parts to strengthen long-term reliability.
