Large Capacity Granule Weighing & Semi-Automatic Bag Filling System
Share to:
This custom four-head weigher packaging machine is specially designed for high-weight granule packaging applications requiring larger weighing capacity. Compared with standard models, the machine features enlarged weighing hoppers, allowing more material per cycle for improved efficiency. The system supports bag filling or container filling, with optional integration to bag sewing machines, heat sealers, capping machines, or lid sealing systems depending on packaging requirements. Combining gravity feeding and vibratory feeding, it delivers stable discharge, accurate weighing, and enhanced packaging speed.
Machine Overview and Functional Description
The customized four-head weigher packaging machine is a semi-automatic quantitative packaging solution designed for large-weight granular products and bulk material filling applications. Engineered with expanded weighing hopper capacity, the machine allows a higher single-weighing volume, making it ideal for customers requiring larger packaging weights and improved throughput.
The system adopts a four-head alternating weighing structure, enabling multiple weighing hoppers to operate simultaneously for faster packaging efficiency and continuous material discharge. Unlike conventional vibratory feeding systems, this customized model combines gravity-assisted material flow with vibratory feeding technology, significantly improving discharge speed while maintaining stable feeding performance, especially after hopper enlargement.
Equipped with high-precision digital load cells, the machine provides accurate and stable weighing performance. A three-stage vibratory feeding system ensures precise dosing, reducing material waste and packaging errors.
The machine is designed for semi-automatic operation, requiring manual bag or container positioning during filling. Finished products can be discharged directly into bags, drums, or rigid containers. Depending on packaging requirements, the machine can be integrated with bag sewing machines, heat sealing machines, capping machines, or lid sealing systems, offering flexible packaging solutions.
Constructed with premium stainless steel contact parts, the machine provides excellent corrosion resistance, dust prevention, and easy cleaning. The detachable weighing hoppers allow quick maintenance and convenient sanitation.
Its PLC-based microcomputer control system features a user-friendly interface, advanced weighing algorithms, and reliable operational stability, ensuring consistent performance across demanding industrial applications.

Structural Design and Working Principle
1. Precision Vibratory Feeding System
The machine adopts a multi-stage vibratory feeder to ensure stable and accurate material discharge. The feeding intensity can be adjusted according to material characteristics, improving weighing precision while minimizing material waste.
2. Independent Dual-Discharge Feeding Structure
Each weighing hopper features an independent discharge system combining gravity flow and vibratory feeding. This hybrid feeding design enhances discharge speed and solves the slow-flow issue commonly caused by enlarged hopper capacity.
3. Intelligent PLC Control System
Equipped with a PLC microcomputer control system and touch-screen interface, the machine provides convenient parameter adjustment, real-time operation monitoring, and reliable packaging performance for various materials.
4. Enlarged Hopper with Visual Inspection Window
The customized enlarged hopper design increases single weighing capacity and improves production efficiency. The integrated visual inspection window allows operators to monitor material flow and hopper conditions in real time.
FAQs
Q1: What materials can this four-head weighing machine package?
This machine is suitable for granular and free-flowing materials, including rice, fertilizer granules, seeds, salt, sugar, detergent granules, feed additives, snacks, and small hardware parts.
Q2: What is the advantage of the customized enlarged hopper?
The enlarged hopper capacity allows more material to be weighed per cycle, making the machine suitable for higher packaging weights and improved production efficiency.
Q3: Is this machine fully automatic?
No. This is a semi-automatic packaging machine, requiring manual bag or container positioning during the filling process while weighing and discharge are automated.
Q4: Can the machine connect to sealing or capping equipment?
Yes. The system can be integrated with bag sewing machines, heat sealers, capping machines, or lid sealing equipment, depending on your packaging format.
Q5: How does the machine maintain weighing accuracy?
The machine combines high-precision digital load cells, three-stage vibratory feeding, and gravity-assisted discharge, ensuring stable feeding and accurate weighing performance even at larger capacities.
