The RZFD-450ATF fully automatic paper bag machine is developed to meet the requirements of continuity and stability in scaled paper bag production. Using roll paper as raw material, the machine integrates processes including paper feeding, side gluing, tube forming, cutting, creasing, bottom gluing, and square bottom forming into a unified production flow. All production stages operate in coordination under a centralized control system, reducing the impact of step-by-step manual operations on production rhythm. This makes the bag-making process more continuous, helps improve overall production efficiency, and ensures consistency of finished products.
In terms of material adaptability and forming control, the machine demonstrates good compatibility with commonly used packaging paper materials and can cover production requirements for paper bags in multiple specifications. During continuous operation, the unwinding, paper feeding, and web guiding systems monitor and adjust paper conditions in real time, ensuring smooth paper transport. This effectively reduces material loss while maintaining stable bag dimensions and square bottom forming quality. The control system coordinates all processes during operation, enabling the machine to maintain a stable production rhythm over long production periods, making it suitable for batch production applications in packaging enterprises.
In terms of operation and structural design, the machine is equipped with a touch-screen human–machine interface, with operating status and key process parameters displayed centrally. Adjustment processes are intuitive and clear, allowing operators with different experience levels to become familiar with the machine quickly. The overall machine structure is well organized, with clearly defined component zones, making routine inspection and maintenance relatively straightforward. Key components are selected and assembled with consideration for durability and long-term operation requirements, ensuring stable performance during continuous industrial production. This makes the RZFD-450ATF fully automatic paper bag machine suitable as a core piece of equipment for printing and packaging enterprises seeking standardized paper bag production.
