Kenwei's Advanced Automatic Quantitative Weighing and Packaging System for Mixed Materials
Rizhao Rongxin currently faces challenges in its granule product packaging process. The factory relies on manual weighing, packaging, and sealing, which is slow, labor-intensive, and inefficient, making it unsuitable for modern production management. To address this, Guangdong Kenwei Intellectualized Machinery Co., Ltd. has designed an advanced automatic weighing and packaging system that provides fast, accurate, and efficient solutions for mixed materials.

System Overview
The system comprises several key components:
-
Vertical Conveyor:
-
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.
-
Multihead Weigher:
-
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.
-
PLC Control System:
-
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.
-
Vertical Packaging Machine:
-
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.
-
Platform:
-
The platform is constructed from stainless steel, offering shock resistance, stability, and ease of cleaning and maintenance.
-
Check Weigher:
-
The check weigher ensures that overweight products are removed from the production line, ensuring that only high-quality products proceed to packaging.
System Performance and Specifications
-
Speed: The system operates at a speed of 35–50 packs per minute (P/M).
-
Accuracy: The system provides a high accuracy range of ±0.1% to ±0.5%.
-
Voltage: 380V/220V
-
Power: Above 4 kW
Material Construction
-
Vertical Conveyor: The belt is made of PT, while the other components are welded from stainless steel.
-
Top Cone and Linear Pan: These are made from stainless steel, ensuring durability.
-
Hopper: Constructed from stainless steel for longevity and cleanliness.
-
Platform: Also made of stainless steel, providing stability and easy maintenance.
-
Standing Packaging Machine: Made entirely of stainless steel for durability.
Cost Savings and Efficiency
Kenwei’s system offers significant cost savings for Rongxin. By automating the packaging process, Rongxin can reduce labor costs by 30-50% annually. Over 10 years, the system can save up to 300-500 labor costs and improve material efficiency, handling up to 15-25 tons of materials annually (based on two shifts of 16 hours per day, 300 days per year).
