The RZFD-190 square bottom paper bag machine with printing inline is developed based on a mature mechatronic design concept. While realizing integrated operation of printing and bag making, the machine places emphasis on long-term operational stability and flexibility in production organization. It is suitable for continuous production of small- and medium-size square bottom paper bags for industries such as food packaging, supermarkets, and daily consumer goods. Typical applications include snack packaging bags, small shopping bags, and daily-use paper bags, meeting the requirements of multiple packaging scenarios.
In terms of operation and control, the machine adopts coordinated servo control and tension management systems, allowing the production rhythm to be adjusted according to actual requirements while maintaining stable paper feeding during continuous operation. Paper tension and position are continuously monitored and corrected during web transport, helping prevent issues such as wrinkling or stretching. This ensures consistency in bag dimensions and appearance. The web guiding system responds quickly to paper position changes during production, further improving feeding stability and reducing material loss caused by production fluctuations.
In terms of structural and maintenance design, the machine is equipped with an automatic lubrication management system, reducing wear on key components during operation. This helps extend service life and lower maintenance frequency. The printing unit and bag-making unit are relatively independent in structure while operating in coordination under the control system, facilitating routine inspection, adjustment, and troubleshooting. The finished bag collection stage is supported by a dedicated stacking structure that arranges paper bags in an orderly manner, reducing subsequent manual handling and making the overall production process smoother. This helps enterprises improve the overall efficiency of square bottom paper bag production.
