DTB
Fully automatic open-mouth bagger for filling granular and powder products into pre-made open-mouth bags
The DTB automatic bagging machine is designed for flexible use across a wide range of bag materials, including laminated woven bags, kraft paper bags, heavy-duty PE film bags, and envelope-style bags. Its structure supports high-speed production with a capacity of up to 800 bags per hour, making it suitable for plants that need both speed and stable performance.
The system uses a stack-type bag magazine equipped with vacuum detection and low-bag alarms, ensuring steady bag supply without jamming. A full negative-pressure monitoring setup helps identify bag defects early; if a bag does not meet requirements, the system rejects it automatically. If a bag is not clamped correctly, the weighing scale will not release material, preventing spills and ensuring clean, controlled filling. The bag-holding trolley is reinforced and driven by a servo motor for precise motion control. This design keeps the bag mouth straight throughout the process, supporting smooth filling, clean transfer, and reliable downstream sealing.

- This open-mouth bagger works with a wide range of bag types, including laminated woven bags, kraft paper bags, envelope-style bags, and heavy-duty PE film bags. The mechanical system supports up to 800 cycles per hour, allowing stable and efficient operation.
- The stacked bag magazine is equipped with a vacuum-detection system and a no-bag alarm to keep bag feeding smooth and uninterrupted. A negative-pressure monitoring system runs throughout the process to identify bag defects in real time. If a bag fails quality checks, the bagging machine automatically rejects it; if the bag is not firmly clamped, the weighing scale will not release material.
