Fully Automated Open Mouth Bagging Machine
The open-top bag filling machine offers a smart and efficient solution for packing powdery and granular materials ranging from 10 to 50 kg into open-top bags. Designed for accuracy and ease of use, it features a precision gravimetric system that automatically controls feed rates through advanced load cell technology — ensuring consistent, reliable filling every time.
With multiple feeding options available — including screw, belt, valve, and vibratory feeding — this machine can be easily adapted to suit a wide range of materials, from fine powders to coarse granules. Its versatile design makes it ideal for diverse industries such as construction, agriculture, chemicals, and food processing.
For a complete packaging solution, the system seamlessly integrates with bag sealing units (sewing or heat sealing) and belt conveyors, delivering a streamlined, automated process that boosts productivity while reducing manual handling.

Process flow
1. Empty Bag Placement Platform
Stores 300–500 empty bags, ensuring a steady supply for continuous operation.
The dual-speed feeding system enables fast feeding to ensure high output, while variable-speed control during slow feeding enhances weighing accuracy.

2. Bag Picking and Delivery Mechanism
Automatically selects and conveys empty bags to the feed opening.
3. Bag Positioning Arm
Precisely positions the bag over the filling spout to ensure proper alignment.
4. Bag Opening System
Opens the mouth of the bag in preparation for filling.
5. Bag Clamping Mechanism
The bag clamping system consists of precision sensors, support brackets, and clamp arms that hold the bag securely during filling. The robust frame structure provides support and stability for the entire unit and minimise spillage.
6. Weighing and Control System
Supported by a stable frame structure, the system uses a pneumatic control system and a central control unit to manage feed valves and clamping operations. When the bag is clamped and sufficient material is available in the storage bin, the valve opens automatically, and filling begins.
The filling process follows a two-stage weighing sequence: fast feed continues until the initial target weight is reached, followed by slow feeding to reach the final target weight. Once achieved, the machine stops filling, displays the final weight, and automatically releases the filled bag.
Simultaneously tidies the bag opening to ensure a neat seal and support further handling.
