Product introduction of 2-head Linear Scale Packing Machine
The 2-head linear scale packing machine is an automated packaging system designed for weighing and packing granular, pellet, and small solid materials into flexible pouches. It integrates film forming, dual-head linear weighing, filling, and sealing functions in one continuous operation. The system supports pillow-type and gusseted bags with customizable dimensions. Equipped with PLC control, servo film pulling, and pneumatic sealing, it ensures stable performance and consistent accuracy. It is widely used in food processing, chemical packaging, and agricultural product industries requiring efficient and precise automated bagging solutions.
Working Principle
The machine first feeds roll film into the forming system to create bag shapes. Granular materials are then measured using a dual-head linear weighing system. The accurately weighed product is filled into formed pouches, followed by horizontal sealing using a pneumatic system. Finished bags are discharged automatically. The PLC system coordinates all steps, ensuring synchronized film pulling, weighing, filling, and sealing for continuous and stable production performance.
