The following is a professional analysis and recommended solution for furniture factories to use weighing scales to remove unqualified materials, combined with industry demand and technical characteristics:

🔧1、 Core functional requirements

1. High precision dynamic weight checking

• Weighing range coverage30kg-800kg(Large furniture materials), with dynamic accuracy of up to±0.05%Suitable for testing irregular materials such as boards and hardware fittings.

• Imported sensors (such as German HBM) are used to resist vibration interference and ensure stability during high-speed operation of the assembly line.

2. Intelligent elimination mechanism

• Air blown type: Non destructive removal of lightweight materials (such as fillers).

• Push rod type: Heavy duty board forced sorting (with a load capacity of up to 800kg) 4.

• Air blown/push rod removalCustomized for different material characteristics:

• Double elimination confirmation design to avoid omissions (such as installing auxiliary air nozzles).

3. Data Management and Traceability

• 10 inch color touch screen operation, pre stored200 sets of product parametersSupport one click switching between different material testing standards.

• Automatically generate Excel format reports, record non-conforming product batches, weight deviations, and exclusion times, and support USB export of 69.

4. Industrial grade durable design

• Full 304 stainless steel bodyResistant to dust, moisture, and suitable for the sawdust environment in furniture factories.

• IP65 protection levelPrevent debris intrusion and extend equipment lifespan by 4.

🏭2、 Recommended mainstream devices

1. JDT-CZ-A30 series (Giant Sky Instrument) 14

• Applicable scenarios: Large sheet metal, metal frame

• parameter：

• Weighing range: 50-800kg (accuracy ± 50g)

• Elimination method: Dual mode of air blowing and push rod

• Function: Three color alarm light, batch statistics, automatic generation of production trend chart

• advantageModular conveyor belt (buckle design), quick belt replacement in 5 minutes.

2. DT series weighing scale (Dingtuo) 38

• Applicable scenariosSmall and medium-sized hardware components, packaging accessories

• parameter：

• Sorting speed: 300 times/minute

• Data interface: RS232/USB, compatible with Modbus TCP

• advantageThe 10 inch touch screen pre stores 1000 sets of formulas and seamlessly integrates with the MES system.

3. JDW-1500 type (Juding Tianheng) 68

• Applicable scenariosHigh frequency sampling assembly line

• parameter：

• Dynamic accuracy: ± 0.5g (weighing small items within 1.5kg)

• Protection: Stainless steel sealed frame

• advantageAutomatic zero point tracking, stable operation even in strong electromagnetic interference environments.

⚙️3、 Key recommendations for selection

1. Exclusion method matches material attributes

• Lightweight foam/fabric→ Air blown (to avoid physical damage) 1

• Heavy duty plates/metal partsHydraulic push rod (forced sorting force ≥ 200N) 4.

2. Requirements for data system integration

• ERP integration is required → optional Modbus TCP or RS232 interface (such as DT series) 3.

• Only local management → basic USB export function (such as JDW-1500) 6.

3. Environmental adaptability optimization

• High dust workshop → Install dust cover+regularly clean sensor 9.

• Wet area → Select IP68 protection model (such as Dingtuo customized model) 8.

⚠️4、 Fault prevention and maintenance

• Frequently Asked Questions：

• Remove delay → Check the air pressure valve (air blowing type) or hydraulic oil level (push rod type) 1.

• Data drift → Daily automatic zero calibration upon startup 6.

• Maintenance Tips：

• The conveyor belt is cleaned weekly (to avoid the accumulation of sawdust affecting accuracy).

• The sensor is calibrated quarterly using standard weights.
