JTJ series fully automatic weight sorting machine: working principle and daily maintenance guide
Date: 2025-12-30Read: 6
In industries such as food, medicine, and chemical, consistency in product weight is crucial for quality control and cost management. The JTJ series fully automatic weight sorting machine, as an efficient online weight inspection equipment, can accurately sort products and ensure compliance with standards. This article provides a detailed analysis of its working principle and offers comprehensive daily maintenance recommendations to help users optimize device performance.
1、 The working principle of JTJ series fully automatic weight sorting machine
1. Basic components
The JTJ series equipment mainly consists of three core modules:
Conveyor mechanism: responsible for uniformly conveying products to the weighing area, ensuring appropriate spacing between products and avoiding interference. Made of stainless steel material, durable and easy to clean, suitable for food and pharmaceutical environments.
Weighing mechanism: The core components include high-precision sensors and high-speed data processors. When the product moves on the conveyor belt, the sensor measures the weight in real time, and the data is sent to the control box for dynamic analysis.
Sorting mechanism: According to the instructions of the control box, overweight or underweight products are removed or distributed to different areas according to the weight range through pneumatic valves, push rods, or levers, achieving automated sorting.
2. Workflow
Weighing process: After the product enters the conveyor belt, the weighing sensor captures the weight signal, and the control box compares the preset range to determine whether it is qualified. This process is completed in high-speed motion to ensure the efficiency of the production line.
Sorting execution: Unqualified products are immediately removed, while qualified products continue to be transported. The sorting method can be customized, such as blowing to remove lightweight products or using a push rod to separate heavy products, to meet various needs.
Feedback mechanism: Some models support weight feedback, which sends data back to the packaging equipment to dynamically adjust the feeding amount, reduce raw material waste, and improve cost-effectiveness.
3. Application scenarios
Food industry: used for sorting fruits, meats, etc. to ensure consistent weight per product and avoid consumer complaints.
In the field of medicine: precise control of drug weight, ensuring dosage accuracy, and complying with industry standards.
Chemical and Electronics: Sorting small parts or raw materials to prevent product loss or mixing errors.
2、 Key points of daily maintenance
1. Cleaning and hygiene
Daily cleaning: Use a soft cloth and neutral detergent to wipe the surface of the equipment to avoid corrosion. Focus on cleaning the conveyor belt and weighing area to prevent residue from affecting accuracy.
Disinfection treatment: In food and pharmaceutical applications, regularly disinfect with alcohol or specialized disinfectants to ensure hygiene and safety.
2. Mechanical component inspection
Conveyor belt maintenance: Check the belt tension to avoid wear or deviation caused by being too tight or too loose. Regularly lubricate bearings to reduce friction losses.
Sensor calibration: Calibrate the weighing sensor with standard weights every month to ensure accurate data. Before calibration, clean the weighing platform to avoid interference from foreign objects.
Pneumatic system inspection: Confirm that the pneumatic valve and push rod operate smoothly without leakage. Check for stable air pressure to prevent delayed or ineffective sorting actions.
3. Electrical system maintenance
Line inspection: Regularly check the power cord and signal connection to ensure there is no looseness or damage. Use a multimeter to detect voltage and prevent fluctuations from affecting the equipment.
Control box maintenance: Keep the control box dry and avoid dust accumulation. Check the display screen and button functions to ensure that the operation interface is responsive.
4. Software and parameter management
Parameter verification: Before starting up, confirm that the sorting rules (such as weight range) have been set correctly. Prevent parameter errors from causing misjudgment or shutdown.
Software updates: Regularly upgrade control software, fix potential vulnerabilities, and improve system stability.
5. Environmental adaptability maintenance
Temperature and humidity control: In humid or high-temperature environments, strengthen equipment sealing checks to prevent sensors from getting damp or overheated. Use moisture-proof agents or ventilation equipment to regulate the environment.
Anti seismic measures: Install shock-absorbing pads to reduce the impact of external vibrations on weighing accuracy, especially in production lines close to large machinery.
6. Fault prevention and troubleshooting
Common problem handling:
Inaccurate weighing: Check the sensor status and calibration records, and clean up foreign objects on the scale platform.
Belt jamming: Adjust tension, remove foreign objects, lubricate transmission components.
Device crash: Restart the system, check power stability, or contact technical support.
Preventive strategy: Establish maintenance logs to record cleaning, calibration, and fault situations for easy tracking of the root cause of problems.
3、 Maintenance precautions
Safe operation: Power off during maintenance to avoid the risk of electric shock. Do not touch moving parts during operation to prevent mechanical injury.
Professional support: For complex malfunctions (such as sensor damage), please contact the manufacturer to avoid disassembling on your own and causing warranty failure.
Employee training: Regularly train operators to ensure familiarity with maintenance processes and emergency measures, and enhance team responsiveness.
Conclusion
The JTJ series fully automatic weight sorting machine greatly improves production efficiency through precision design and automated processes. By following the above maintenance guidelines, users can extend equipment lifespan, reduce downtime, and ensure consistency and reliability in product sorting.
