Servo High-Speed Drive — RZFD-190 Production Line for Leading Mass Production of Small and Medium Square Bottom Paper Bags

The RZFD-190 square bottom paper bag machine production line is systematically designed to meet the continuous mass production requirements of small- and medium-size paper bags. It integrates processes such as unwinding, paper feeding control, tube forming, cutting, and square bottom forming into a unified operating rhythm, enabling the entire line to achieve continuous output under stable conditions. Structurally, the machine is closer to an integrated production unit, with all processes coordinated through a unified control logic, reducing rhythm fluctuations caused by segmented equipment coordination. During operation, paper feeding and positioning are continuously corrected, allowing the paper to maintain a stable path even at high speed. This improves the regularity of square bottom forming and helps maintain consistency in batch production.

In terms of production adaptability and forming control, the machine is optimized for small- and medium-size paper bags commonly used in food and fast-moving consumer goods packaging. It can accommodate continuous processing requirements of different types of roll paper materials. The unwinding and conveying processes operate under coordinated tension management and web guiding systems, ensuring that the paper remains stable before entering the forming section and reducing the impact of stretching or deviation. The gluing and pressing stages focus on uniform transfer, allowing the bag bottom structure to maintain stable bonding under different operating speeds. This contributes to improved sealing performance and reliability of finished products. Under continuous production conditions, the line maintains a stable output rhythm, making it suitable for sustained batch production.

In terms of operation and production line application, the control system centrally manages key process parameters, making operation more intuitive and facilitating quick adjustments between different orders. The overall machine adopts a zoned modular structure, allowing each functional unit to be maintained independently and reducing the impact on overall production. The design takes into account workshop conditions and long-term operation requirements, enabling stable performance under standard industrial environments. For enterprises focusing on small- and medium-size paper bags, the RZFD-190 square bottom paper bag machine production line is well suited as a foundational line for continuous mass production, maintaining production rhythm while ensuring product consistency and operational stability.
