Our Complete Tailored Solution

Core System Units

1. 14-Head 5L Multihead Weigher (Stamped Dimple Plate) + 1-2 Temporary Distributors: High-precision weighing with anti-stick dimple plate for fresh vegetables, flexible material distribution for bag and carton production lines

2. Food-Grade Working Platform: Ergonomic, safe operation and maintenance access, compliant with food workshop standards

3. Vertical Form Fill Seal (VFFS) Packaging Machine: Automatic forming, filling and sealing for 2kg retail vegetable bags

4. Finished Product Conveyor: Gentle, damage-free transfer of bagged products to subsequent inspection stations

5. CW300 In-line Check Weigher: 100% weight verification for bagged products, real-time rejection of non-compliant items

6. High-Sensitivity Metal Detector: Detects ferrous, non-ferrous and stainless steel foreign bodies to guarantee food safety

7. Intelligent Temporary Storage Device: Buffers weighed materials for 10kg bulk carton packaging, completing target weight filling in 2-3 cycles

8. Automatic Carton Conveying Line: Realizes automatic carton feeding, positioning and continuous conveying for bulk packaging

9. CW500 Carton Check Weigher: Final weight re-inspection for finished cartons, ensuring full compliance with weight standards

   
   

Standard Automated Workflow

1. Material Feeding: Fresh vegetables are manually poured into the inclined elevator hopper, which automatically lifts materials to the inlet hopper of the multihead weigher.

2. Weighing & Distribution: The multihead weigher completes high-precision weighing, then discharges materials into the temporary storage bin. The distributor allocates materials to the bag packaging line or carton packaging line according to production demand.

3. Retail Bag Packaging Process: The vertical packaging machine sends a filling request for 2kg target weight bags. Bagged products are transferred via the finished product conveyor to the CW300 check weigher for weight verification, then pass through the metal detector for foreign body inspection.

4. Bulk Carton Packaging Process: The temporary storage device sends a filling request for 10kg target weight cartons, with the weigher completing filling in 2-3 cycles to ensure accuracy. When the carton reaches the discharging station, the sensor triggers a feeding signal: the guide bucket lowers into the carton, and the scraper hopper door opens for discharging.

5. Final Inspection & Output: After discharging is completed, the carton blocking cylinder of the conveying line retracts, and the filled carton is conveyed to the CW500 check weigher for final weight re-inspection, completing the full packaging process.
