Packaging online leak detectorIt is a device used for real-time detection of packaging sealing performance, widely used in industries such as food, medicine, and daily chemical to ensure the quality and safety of products during production, transportation, and storage. This device adopts advanced non-destructive testing techniques, such as vacuum attenuation leakage testing, ultrasonic testing, CO ₂ tracer gas detection, etc., which can accurately identify small leakage points without damaging the packaging. Its core technologies include high-precision sensors, automated control systems, and data analysis software, which can achieve full process automated detection. For example, equipment based on vacuum attenuation method determines sealing by monitoring pressure changes inside and outside the packaging, while CO ₂ detection system uses gas molecule tracking technology to locate the leak location.
Packaging online leak detectorCharacteristic analysis:
1. Efficiency and production adaptability
Real time online detection: can be directly integrated into the packaging production line, achieving 100% full inspection without interrupting the production process, and improving detection efficiency.
High speed detection capability: For example, vacuum attenuation leak detectors (such as ATEQ equipment) can detect up to 20 boards/minute, or even up to 120 boards/minute, meeting the needs of large-scale production.
Multi specification adaptation: It can detect different packaging forms (such as bagged, bottled, canned, BFS inline packaging, etc.) and adapt to multiple sizes through customized cavities or robotic arms.
2. Accuracy and sensitivity
Strong micro leak detection capability: using vacuum attenuation method, CO ₂ tracing method and other technologies, it can detect small leaks (such as 3-micron leakage points), avoiding the problem of micro leaks that cannot be identified by traditional water inspection methods.
Quantitative analysis: not only can it determine "pass" or "fail", but it can also provide quantitative data such as leakage rate and leakage size to help optimize production processes.
Error prevention design: By using technologies such as automatic constant pressure air supply and pressure sensor calibration, errors caused by human operation or environmental factors can be reduced.
3. Non destructive and safety
Non destructive testing: The testing process does not damage the packaging or product, especially suitable for industries such as medicine and food that require high product integrity.
Safety and environmental protection: For example, the vacuum decay method does not produce ozone or high-voltage arcs, avoiding harm to products (such as flammable drugs) or personnel.
Strong compatibility: Can detect packaging containing small amounts of liquids or sensitive ingredients (such as BFS packaging), avoiding the impact of traditional high-voltage discharge methods on product oxidation or stability.
4. Automation and Intelligence
Fully automated process: integrating robotic arms, conveyor belts, and automatic sorting systems to achieve automatic loading, inspection, and classification (qualified/unqualified products), reducing manual intervention.
Intelligent data management: Real time recording of detection data (such as leakage rate, statistical trends), supporting remote monitoring and quality traceability.
Flexible integration with production lines: It can be linked with front-end equipment such as die-cutting machines and blowing and sealing equipment, automatically start and stop according to production status, and improve the collaborative efficiency of the production line.
5. Diversified technology applications
Vacuum attenuation method: Identify leaks by monitoring changes in vacuum level, suitable for most packaging forms such as soft bags, bottles, and blister packaging.
CO ₂ tracer method: using CO ₂ as the reference gas, leakage is detected through pressure difference, suitable for non-destructive testing of modified atmosphere packaging (such as milk powder and fresh meat).
Ultrasonic technology: combined with image analysis, non-contact detection of the sealing of soft packaging.
