100% Accuracy Guarantee – Multi-layer verification (barcode matching, rechecking, weighing) ensures zero labeling or addressing errors.
Intelligent Sorting – Automatically sorts envelopes into multiple destination boxes based on barcode data.
Modular, Expandable Design – Built from interchangeable functional modules for easy maintenance and future expansion.
Industrial-Grade Reliability – Designed for continuous operation (≥16 hours) with a service life of ≥10 years.
How It Works – Complete Workflow
The ZWD-AL-805 performs a seamless sequence of automated operations:
| Step | Operation | Description |
|---|---|---|
| 1 | Express Envelope Feeding & Opening | Continuous drawing feed method with closed-loop motor vacuum suction for stable, jam-free operation. |
| 2 | Small Window Envelope Feeding | Pre-packaged card envelopes are automatically fed into the system. |
| 3 | Barcode Reading | Reads the barcode on the small window envelope at 100% identification rate. |
| 4 | Data Matching | Compares barcode data with computer records to retrieve the correct recipient information. |
| 5 | Insertion & Sealing | Small envelope is automatically inserted into the express cardboard envelope, followed by spray adhesive application and sealing. |
| 6 | Label Printing & Application | Recipient address label is printed and automatically dispensed onto the outer envelope surface. |
| 7 | Rechecking & Weighing | Barcode reader verifies the applied label matches the original envelope data. Integrated weighing confirms contents are correct. |
| 8 | Intelligent Sorting | Based on barcode information, envelopes are automatically sorted into designated receiving boxes. |
| 9 | Defect Rejection | Any envelope that fails reading, weighing, or labeling verification is automatically diverted to a waste/elimination box. |
Key Features
1. Fully Automatic Operation
The machine requires minimal operator intervention. From feeding to sorting, every step is controlled and monitored automatically, ensuring consistent, high-speed production.
2. Continuous Feeding Design
Both express cardboard envelopes and small window envelopes use a continuous drawing feeding method, allowing non-stop operation without manual reloading during production runs.
3. 100% Barcode Identification Rate
Advanced barcode reading technology achieves a perfect 100% read rate, ensuring that no envelope proceeds without accurate data association.
4. Multi-Layer Verification for Zero Errors
Barcode Rechecking: After labeling, the system reads the applied label and compares it with the original envelope barcode.
Weighing Function: Detects missing cards or inserts to prevent incomplete packages from being shipped.
5. High-Speed Intelligent Sorting
Envelopes are automatically directed to multiple sorting boxes based on customer-defined criteria (e.g., destination region, postal route, delivery service). Sorting efficiency reaches 100%.
6. Modular Design for Scalability
The system is composed of interchangeable functional modules. Modules with identical functions can be swapped, and the system can be easily expanded as production volumes grow.
7. Industrial-Grade Construction
Continuous Operation: ≥16 hours
Control System Uptime: 32 hours
Design Life: ≥10 years
Standardized mechanical and control parts for reliable interchangeability
8. User-Friendly Maintenance
The control cabinet features a well-organized structure with clearly marked wiring points, simplifying troubleshooting and routine maintenance.
