The RZFD-250 square bottom paper bag machine is developed based on a mature mechatronic design concept. Through systematic integration of mechanical structure and control systems, the machine demonstrates strong adaptability under different production conditions. It is suitable for continuous production of square bottom paper bags across multiple industries and batch types, and can be used to build paper packaging production lines with stable operation and controllable production rhythm.
In terms of operation and control, the machine adopts a centralized control system combined with servo drive configuration. The production rhythm can be flexibly adjusted according to order requirements, maintaining stable finished bag quality while ensuring output efficiency. For printed paper bag production scenarios, the machine is equipped with dedicated pattern recognition and positioning control functions, allowing the paper to maintain good positioning consistency during bag forming. This helps reduce finished product fluctuations caused by pattern misalignment and improves overall production controllability.
Regarding equipment configuration and process expansion, the machine demonstrates good adaptability to commonly used raw material specifications, reducing the impact of frequent material changes on production rhythm. At the same time, functional modules such as printing can be configured according to actual enterprise needs, enabling expansion of bag-making processes on the basis of existing equipment and supporting customized production requirements. The overall machine structure is clearly arranged, and key components are designed with a balance between durability and maintenance convenience. Routine inspection and maintenance operations are relatively simplified, helping reduce downtime and control long-term maintenance costs. At present, this model has been put into use in application scenarios including food packaging, supermarket shopping bags, agricultural supplies, and daily chemical products. In line with the development direction of eco-friendly packaging, it provides stable and sustainable equipment support for paper packaging production across different industries.
