Products such as toast, bread, dried fruits, and snacks have relatively high requirements for the folding structure, edge sealing, and batch consistency of paper bags. The RZJD-G350J flat bottom paper bag machine is designed for processing small- and medium-size food paper bags, continuously integrating roll paper unwinding, constant-tension paper feeding, photoelectric positioning system, creasing, constant-temperature gluing system, flat bottom folding, fixed-length cutting, and collection. Once the paper material is loaded, the machine can complete bag making according to the preset process, reducing manual finishing and semi-finished product handling while facilitating continuous order production for food packaging enterprises.
The machine adopts a synchronized servo control system and uses a photoelectric tracking device to monitor the paper running position. When web deviation occurs, the web guiding mechanism can make corresponding adjustments, reducing the possibility of paper wrinkling, crease deviation, and bag shape misalignment. For commonly used materials such as food-grade greaseproof kraft paper, coated packaging paper, and pre-printed paper, paper feeding and gluing parameters can be adjusted according to paper thickness, surface condition, and extensibility. The flat bottom folding and edge sealing stations operate in coordination, helping maintain relatively uniform bonding areas and meet the practical requirements of bakery food packaging for grease resistance and crumb containment.
The touchscreen interface can store multiple sets of bag specifications. When changing product specifications or paper materials, the corresponding parameters can be recalled and then fine-tuned according to trial-run conditions, reducing repeated setup time. Shutdown alarm functions for material shortage, paper jams, and overloads allow operators to troubleshoot abnormalities in a timely manner, while the automatic lubrication structure facilitates routine maintenance. For packaging plants handling multi-batch food paper bag orders, the machine provides effective coordination between order changeover efficiency, material compatibility, and finished bag consistency.
