Auto Precision Weighing And Dosing System For Low Smoke Halogen Free LSHF Cables

This system is an automated processing solution designed for additive materials, covering the entire workflow from unpacking, dosing, and temporary storage to final feeding. By integrating functions such as barcode recognition, automated dosing, dust collection and recovery, and material transfer, the system aims to standardize the additive feeding process, achieve traceability, and reduce manual labor.

1. Raw Material Feeding Barcode System for Error Prevention
   The feeding station is equipped with a barcode scanner. Operators are required to scan the barcode on the material's outer packaging. The system automatically verifies whether the material information matches the production order to prevent incorrect feeding.
2. Dust Collection System with Intelligent Recovery
   Dust collection points are installed at stations prone to dust generation, such as unpacking and feeding. Collected dust can be designed for recovery according to process requirements, minimizing material loss and environmental pollution.
3. Customized Material Storage and Conveying/Dosing Methods
   Based on the physical characteristics of the materials (e.g., flowability, hygroscopicity, bulk density) and process requirements, the system can be configured with appropriate storage silos, conveying equipment (e.g., screw conveyors, vacuum conveyors, tubular chain conveyors), and dosing units.
4. Dosing Efficiency and Accuracy
   • Dosing Efficiency: The system is designed with a processing capacity of up to ≤70 batches per hour. Actual throughput is influenced by material characteristics, formula complexity, and equipment configuration.
   • Dosing Accuracy: The typical dosing accuracy of the system is ±2 grams or ±5% (whichever is greater, based on the actual weighed value). This accuracy serves as a reference for equipment performance under standard materials and operating conditions.
5. Integration with Automated Packaging and Transfer
   The system can interface with automatic bag-making and bag-placing devices, as well as material transfer systems (e.g., AGVs/conveyors), enabling a connected workflow of "dosing – packaging – transfer – feeding" to reduce manual handling and intervention.

1. Unpacking & Temporary Storage: Manual or assisted unpacking, with materials fed into a temporary holding hopper.
2. Automated Dosing: Materials are conveyed according to the formula requirements to a batch-weighing scale for dosing.
3. Packaging / Temporary Receiving: Dosed materials can proceed to automatic bag-making and bag-placing for packaging or be temporarily held in intermediate containers.
4. Transfer & Feeding: Packaged products or intermediate containers are transported via an automated transfer system to designated feeding points to complete the process.

• Cohesive Process Flow: Covers multiple steps from raw material to feeding point, minimizing material transfer and exposure.
• Error Prevention and Traceability: Material and task binding is achieved through the barcode system, with operational data logged to support quality traceability.
• Flexible Configuration: Modular design allows for customization based on production line layout and material characteristics.

Suitable for continuous or batch production processes in industries such as plastics, rubber, coatings, and food, where precise dosing and feeding of various additives (e.g., color masterbatches, antioxidants, lubricants, functional additives) is required.

The actual operational efficiency and accuracy of the system are influenced by material properties (e.g., viscosity, hygroscopicity, particle uniformity), environmental conditions (temperature and humidity), and routine maintenance levels. It is recommended to conduct suitability testing using typical material samples during the project's preliminary phase to confirm equipment selection and parameter settings.
