Station packaging unit machine is the classical model for bag feed fully automatic packaging, can independently complete such works as bag pickup, date printing, bag mouth opening, filling, compaction, heat sealing, shaping and output of finished products, etc. It is suitable for multiple materials, the packaging bag has wide adaptation range, its operation is intuitive, simple and easy, its speed is easy to adjust, the specification of packaging bag can be changed quickly, and it is equipped with the functions of automatic detection and safety monitoring, it has outstanding effect for both reducing loss of packaging material and ensuring sealing effect and perfect appearance. The complete machine is made of stainless steel, guaranteeing hygiene and safety. s-shaped bag feed packaging machine adopts servo motor for its main power, the merit is stable operation and fast speed, when a fault occurs with the metering scale or there is no material, the packaging machine does not run and stops and waits for material, when the metering scale discharges material, the packaging machine runs automatically, thus not only improving production efficiency, but also reducing wastage of packaging bags. Suitable form of bag: four-side-sealed bag, three-side-sealed bag, self-standing bag, handbag, zipper bag, plastic bag with cover, paper-plastic bag, etc. Suitable material: materials like liquid, sauce, granules, powder, material of irregular shape, etc.Material of the packaging bag: preformed bag and paper-plastic bag etc. Made of multiply composite film. technical parameters: model bag size mm metering range g packaging speed bagsmin control motor cf6-200a w:100-200mm l:100-300mm 5-1000 25-45 variable frequency motor cf6-200a-s w:100-200mm l:100-300mm 5-1000 25-45 servo motor cf6-300a w:180-300mm l:200-500mm 100-2500 20-40 variable frequency motor
