Granule Automatic Weighing and Packaging Machine

The GAOXIN Granule Automatic Weighing and Packaging Machine is a fully integrated solution designed for plastic pellet homogenization, automatic weighing, bagging, sealing, and conveying. Widely used in PE, PP, PVC, ABS, PS, engineering plastics, and recycled granule production lines, this system helps manufacturers improve packaging accuracy, production efficiency, and final product consistency while reducing labor costs and dust pollution.

Built for modern extrusion granulation workshops, the machine supports continuous automated operation from raw material conveying to finished bag output. It is especially suitable for high-output plastic recycling plants, compounding factories, masterbatch production, and pellet manufacturing facilities seeking stable, traceable, and intelligent packaging solutions.

Core Features of the Granule Automatic Weighing and Packaging Machine

Intelligent Homogenization System

The system includes a large-capacity homogenizing silo or mixing hopper that ensures even distribution of pellet color, size, and material composition before weighing and packaging.

Benefits include:

• Reduces batch-to-batch material variation
• Improves pellet color consistency
• Enhances product stability for downstream processing
• Ideal for recycled plastics and masterbatch blending
• Optional multi-material proportion mixing system
  

This section is particularly valuable for manufacturers producing high-quality engineering plastic pellets or color-sensitive products.

High-Precision Automatic Weighing

The Granule Automatic Weighing and Packaging Machine adopts advanced load-cell sensors and PLC intelligent control technology for stable and accurate measurement.

Weighing Characteristics

The multi-stage feeding design ensures both high speed and precise final weight control, minimizing material waste and overfilling losses.

Fully Automated Packaging Process

1. Material Conveying & Storage

Plastic pellets are transported through elevators, pneumatic conveying systems, or screw conveyors into the homogenization storage silo.

2. Uniform Mixing & Homogenization

The stirring system continuously mixes pellets to ensure stable quality before entering the weighing stage.

3. Automatic Weighing

Materials enter the weighing hopper where intelligent sensors perform high-speed quantitative measurement.

4. Bag Clamping & Filling

After reaching the target weight, the machine automatically clamps the bag opening and fills the bag efficiently with minimal dust leakage.

5. Compacting & Shaping

Optional vibration or compacting devices remove excess air inside the bags, improving stacking stability and transportation convenience.

6. Automatic Sealing & Output

Finished bags are automatically transferred to sealing equipment, sewing machines, heat sealers, or conveyor systems for final output and palletizing.

Multiple Packaging Options

The Granule Automatic Weighing and Packaging Machine supports various packaging materials and sealing methods.

Compatible Bag Types

• Woven bags
• Kraft paper bags
• Paper-plastic composite bags
• Valve bags
• Jumbo bags (optional customization)
  

Optional Sealing Methods

The flexible design allows fast switching between different bag specifications and production requirements.

Dust-Free & Low-Maintenance Design

To improve workshop cleanliness and operational safety, the system adopts a fully enclosed structure combined with pneumatic or servo-driven components.

Advantages Include

• Reduced dust leakage
• Lower cleaning frequency
• Minimized pellet spillage
• Improved workshop environment
• Reduced risk of dust accumulation
  

The user-friendly touchscreen interface stores multiple production recipes for different materials such as ABS, PP, PVC, and recycled pellets, simplifying operation and changeovers.
