The RZFD-330TF square bottom paper bag machine with twisted and flat handle inline is designed to meet the switching requirements of multiple types of handle paper bags. It integrates both twisted and flat handle structures within the same production system, allowing different product types to be completed continuously on a single machine. During operation, the handle type can be changed through parameter adjustment without replacing core components, avoiding frequent production interruptions caused by handle variation. After entering the machine, roll paper completes top edge processing, handle forming, and bag forming in sequence, with all processes coordinated under a unified control system, helping maintain a stable production rhythm in multi-product environments.
In terms of adaptation between different handle structures, the machine applies unified management to positioning and bonding processes, allowing twisted and flat handles to follow a relatively consistent processing path during switching. Handle positioning is completed before bonding, ensuring continuous coordination with bag forming and reducing deviation accumulation caused by switching. During paper transport, tension control and web guiding systems continuously adjust the paper path, maintaining stable feeding conditions and helping ensure consistent bag shape and edge quality under different production conditions. The coating and pressing processes are based on uniform transfer, allowing both handle types to achieve reliable bonding performance in use.
In terms of operation and production organization, the machine centrally manages handle types and bag specification parameters, enabling fast switching between multi-specification orders. The machine adopts a modular zoned structure, allowing each unit to be maintained independently and reducing the impact on overall operation. The design takes into account both continuous production and flexible scheduling requirements, making it suitable for multi-batch and multi-type parallel production environments. In practical application, this model serves effectively as a flexible processing unit for medium-size handle paper bag production, improving switching efficiency and adaptability while maintaining product stability.
