🛠 Machine Description :
✅Bag Bottom Forming Module
Blowing Bottom Opening Mechanism: Solenoid valves control the front and rear air blowing mechanisms. High-pressure air precisely opens the bag bottom, preforming a hexagonal shape for the bottom folding process.
Hot Sealing Unit: Instantaneous high-temperature lamination creates a sealed edge, ensuring water and leak resistance.
✅Intelligent Control System
Human-Machine Interface: A touchscreen provides centralized control, displaying real-time fault alerts and allowing fine-tuning of parameters (such as temperature and speed).
PLC + Photoelectric Detection: A photoelectric sensor coupled to a servo motor enables functions such as no-material shutdown and bag clamping detection.
✅Multifunctional Actuator
Clamping System: The folding and bag opening clamping plates work together to secure the bag. A vibration mechanism compacts the contents and reduces air in the bag.
Valve Tape Mechanism: Automatically applies reinforced liner paper to improve load-bearing capacity.

🛠 Machine Features:
✅Seamless production chain: Integrates loading, flanging, tube forming, hot-stamping and sealing, cutting, bottom opening, bottom folding, and bottom lamination, reducing manual intervention and significantly improving efficiency.
✅Hexagonal bottom forming: Front and rear high-pressure air blowers precisely open the bottom, creating a hexagonal structure. Combined with hot-stamping technology, this system provides physical leak prevention.
✅Dynamic adjustment mechanism: The folding clamping plate is equipped with a gap/height adjustment module (limiting blocks + telescopic rod) to accommodate different paper weights.
The air blow angle is adjustable (rotating rod + sprocket drive) to prevent airflow deviation and bag shape distortion.
✅Energy-saving design: An automatic lubrication system reduces energy consumption, and a variable-frequency motor drives the material feeding process to reduce idling losses.
Specialized for laminated paper bags: Compatible with waterproof materials such as laminated kraft paper and medical paper, the hot-stamped lamination layer enhances impermeability.
✅Glue-free process: Instead of traditional gluing of the sides, hot-stamping is used to form the sides, eliminating the risk of cracking.
