Machine Overview and Functional Description
The automatic single-station premade pouch packaging machine with dual linear weigher is a highly efficient packaging solution designed specifically for high-quality premade bags requiring excellent appearance and sealing performance. The system integrates a dual direct-flow linear weigher, a single-station automatic pouch feeding machine, and a stainless steel operator platform, creating a complete semi-automatic weighing and fully automatic pouch packaging solution.
The lower section adopts a single-station automatic premade pouch packing machine, which completes pouch picking, opening, coding, filling, sealing, and finished bag discharge through a single working station. The machine is compatible with various pouch formats, including premade pouches, stand-up pouches, three-side seal bags, and four-side seal bags.
The upper weighing system features a dual direct-flow linear weigher combined with dual vibratory feeders, ensuring faster feeding speed and higher weighing accuracy. The system supports alternating discharge or parallel discharge modes, significantly improving packaging efficiency while maintaining stable dosing performance.
Equipped with an advanced PLC control system and HMI touch screen, operators can easily adjust packaging parameters for different products and pouch specifications. The adjustable bag holding mechanism enables quick pouch size changes, making the machine suitable for packaging larger finished bags with filling ranges from 10g to 5kg.
The equipment adopts a fully stainless steel frame and electrical cabinet, ensuring durability, hygiene, and compliance with industrial production standards. The modular structure reduces maintenance costs and simplifies component replacement.
For enhanced safety and reliability, the machine includes multiple intelligent protection functions such as safety door stop, no bag/no fill alarm, pouch opening failure diagnosis, heater fault warning, cylinder fault detection, and air pressure monitoring system.
