Automatic Packaging Machine for Fertilizer Bags

Feature



High Precision Weighing System

The machine uses three or more high-accuracy load cells. Advanced digital processing ensures each bag is weighed precisely. This improves product consistency and reduces material loss.



Adaptive Feeding Logic

Fast, medium, and slow feeding modes are combined. The system adjusts automatically based on material flow. It works well for granules, powders, and mixed fertilizers.



Heavy-Duty Anti-Corrosion Design

Material-contact parts use stainless steel 304. The machine resists corrosion from NPK and organic fertilizers. It supports long-term operation in harsh environments.



Anti-Clogging Structure

The machine is equipped with vibration or anti-arching devices. It prevents blockage caused by wet or sticky materials. This ensures continuous and stable feeding.



Dust-Free & Sealed Design

The structure is enclosed to reduce dust leakage. Dust collection ports are reserved for environmental control. This improves the working environment.

Structure

Weighing Unit

The core system measures material weight in real time. It ensures accurate control of each packaging cycle.

Feeding Device

The mechanism controls material flow into the weighing hopper. Depending on the model, it can use gravity, screw, or belt feeding to suit different material characteristics.

Conveyor System

The conveyor system automatically transports filled bags, reducing manual handling and improving workflow efficiency.

Bag Closing Unit

The machine can be equipped with sewing or sealing systems. It ensures tight and secure packaging.

Control System (PLC + HMI)

The intelligent control system allows parameter setting and monitoring. Operators can quickly adjust packaging weight and speed.

Principle

Materials enter the weighing hopper through the feeding system. The machine uses multi-stage feeding to approach the target weight. When the preset value is reached, feeding stops automatically. The discharge gate opens and fills the bag. Then the bag is conveyed and sealed. The system repeats the cycle continuously.

Application

Compound Fertilizer Packaging

Suitable for NPK fertilizer granules and powder materials. Ensures accurate bagging and clean packaging.

Organic Fertilizer

Handles moist and uneven materials with anti-clogging design.

Chemical Industry

Used for packaging powder and granular chemical products.

Feed and Grain Industry

Suitable for feed pellets, grains, and bulk materials.

Advantage



High Automation Level

The system integrates weighing, filling, conveying, and sealing. It reduces labor demand and improves efficiency.



Wide Packaging Range

One machine supports 5kg to 50kg bags. It can adapt to different market needs.



Easy Operation

The PLC system simplifies operation. Workers can learn quickly and adjust parameters easily.



Clean and Safe Production

Dust control design reduces pollution. It supports safer and cleaner production environments.

FAQ

1. How to choose the right model for different plant capacities?

Model selection depends on required output (bags/hour), material type, and bag size. For higher capacity lines, dual-scale or parallel systems are recommended to maintain stable throughput.

2. What factors affect long-term weighing accuracy?

Environmental vibration, dust accumulation, and improper calibration may affect accuracy. Regular inspection and calibration help maintain stable performance.

3. Can packaging data be recorded or connected to factory systems?

Yes. The control system can support data output and can be connected to plant management systems if required for better production tracking.

4. What optional configurations are available?

Optional components include dust collectors, automatic bag feeding units, and palletizing systems to further improve automation and reduce labor costs.
