Bag Air Tightness Testing machine
1.Using extrusion method and advanced force analysis algorithm, the fastest output can reach 400 bags / min.
2.It is suitable for nitrogen flled and other inflatable bagged food products
Product Introduction
1. Performance Overview
The Bag air tightness testing machine is a fully automatic functional inspection system designed to process up to 300 packages per minute. Using a contact-type online inspection method, it directly evaluates the internal pressure status of packaged products and delivers consistent, reliable test data. Compared with comparable domestic and international equipment, it offers higher detection accuracy and improved performance stability.
The system is built around advanced belt-compression detection technology developed through more than a decade of continuous research and practical application. During conveying, a flexible clamping belt applies controlled pressure to the product, while a side-mounted sensor monitors the corresponding internal pressure changes. The controller transforms the acquired signals into digital information, which is then analyzed to determine package pressure conditions and sealing quality.

II. Equipment Installation
1. Transportation, Handling, and Storage
Pack and transport the machine securely, ensuring the sensor is protected from compression and pulling forces.
Use moisture-resistant and shock-absorbing packaging materials to prevent scratches, dents, or water exposure.
Secure the equipment firmly during transportation to avoid shifting.
Use appropriate lifting devices during unloading and ensure stable placement.
Recommended environmental conditions: relative humidity 10–80%, operating and storage temperature 0–50°C.
2. Installation Requirements
2.1
Install the machine on a level surface, ensuring the clamping conveyor belt remains parallel to the bottom conveyor belt.
2.2
Before connecting power, inspect all wiring and verify proper grounding of the control cabinet.
2.3
Power supply requirements: Single-phase AC 220V, 50Hz, 250W.
2.4
Air supply requirements: 4–8 bar compressed air meeting industrial quality standards.
2.5
For optimal inspection accuracy, install the system along a straight conveyor section of 1.5–2 meters and inspect products only after sufficient cooling.
