Core Technical Features
1. Professional UV Optical Sorting System
- High-Sensitivity Fluorescence Detection
Captures fluorescence signals with a resolution of 0.1mm², detecting weak fluorescence emitted by aged PET under UV LED excitation, as well as the strong blue-white fluorescence from OBA-contaminated materials.
- Customized Optical Solution
Specifically designed for UV detection of PET flakes, optimizing inspection accuracy and stability.
2. High-Efficiency & Stable Feeding and Sorting Platform
- Uniform Spread Technology
A high-frequency vibratory feeder ensures even distribution of flakes, effectively reducing material overlap and improving sorting efficiency.
- Modular Chute Design
Available with 4, 6, 8, or 10 channels to flexibly meet different capacity requirements.
- Industrial Dust-Proof Design
Sealed sorting chamber and electrical cabinet, combined with an integrated dust control system, ensure reliable operation even in high-dust environments.
3. High-Performance Pneumatic Ejection System
- Fast & Precise Ejection
Optimized valve design balances durability, response speed, and air consumption, maintaining stable ejection performance at high throughputs.
- Flexible Adjustment
Adaptable to typical flake sizes (3–15 mm) with adjustable parameters to suit various material specifications.
4. Intelligent Control & Remote Support
- 15-Inch Industrial Touchscreen
Intuitive HMI with multi-language support and one-click changeover of product sorting parameters for easy operation.
- Comprehensive Remote Support
Enables remote access and real-time monitoring, featuring a performance data dashboard, online expert diagnostics, and interactive troubleshooting for efficient equipment maintenance.
