Machine Features

1.  Splicing Technology: Utilizing independently developed double-splicing technology, the machine ensures precise paper bag dimensions and precise shaping. It can splice two smaller paper bags into one large one, eliminating the need for additional large-scale equipment and materials, significantly reducing production costs and investment.
2.  Efficient Automation: This machine features a fully automated process, completing the entire production process from raw materials to finished bags, including automatic bag splicing, header card application, tube forming, accordion folding, bottom pulling, bottom card application, bottom gluing, bottom forming, and finished bag finishing.
3.  Intelligent Control: The main control circuit utilizes an imported single-chip microcomputer, a human-machine interface, and variable frequency control. Parameter setting is quick and easy, and operation is centralized and intuitive, achieving fully user-friendly, fully automatic operation. Digital fault self-diagnosis provides clear fault diagnosis at a glance, facilitating quick and easy maintenance and adjustments.
4.  Reduced Labor Costs: With a high degree of automation, the entire production process can be completed by only one person, eliminating 3-5 labor costs and intermediate handling steps. Easy to learn, it saves labor costs and offers a more user-friendly experience. 
5.  Durability and Easy Maintenance: The dual-frequency design features a simple mechanical structure, minimal wear, easy maintenance, and a long service life.
6.  Key Components: The entire machine utilizes renowned brand components such as the German Rexroth dual-servo control system, Siemens PLC, and frequency converter, ensuring stable performance, high efficiency, and durability.
7.  Environmentally Friendly Materials: The bonding process primarily utilizes environmentally friendly water-based and hot-melt adhesives, meeting food packaging safety standards. The machine structure is easy to clean and maintain, reducing waste generation.
8.  Material Compatibility: Supports a variety of paper materials (120-350g/m²), including kraft paper, white cardboard, and coated paper.
