Kenwei's Advanced Automatic Quantitative Weighing and Packaging System for Mixed Materials

System Overview

The system comprises several key components:

1. Vertical Conveyor:

2. This conveyor elevates the seafood storage hopper to the multihead weigher. The hoist is controlled by a combined balance system, with a photoelectric detector that automatically stops the hoist when the storage hopper is full, ensuring smooth operation.

3. Multihead Weigher:

4. Kenwei utilizes the world's most advanced digital weighing sensors for precise measurement. The intuitive Chinese display menu ensures easy operation. For weighing the 1200g product, a 14-head multihead weigher is used, while the remaining products (300g, 15g, 5g) are weighed with 10-head multihead weighers. This system ensures high-speed, high-accuracy weighing of mixed materials.

5. PLC Control System:

6. The programmable logic controller (PLC) system aggregates control, managing multiple multihead weighers simultaneously. Each weigher is adjusted based on the weight and cutting speed, with precise control over the storage and discharge process.

7. Vertical Packaging Machine:

8. The vertical packaging machine is made of stainless steel, featuring double-belt pulleys, a Mitsubishi PLC, and a servo controller. The machine receives signals from the timing controller, which triggers the packaging process: material is deposited into the bag, sealed, and then sent to the next work cycle.

9. Platform:

10. The platform is constructed from stainless steel, offering shock resistance, stability, and ease of cleaning and maintenance.

11. Check Weigher:

12. The check weigher ensures that overweight products are removed from the production line, ensuring that only high-quality products proceed to packaging.
