Automatic Bottle Leak Detection Equipment with Pressure Drop Testing and

This equipment is a compact, fully automatic, single-station inline empty bottle leak tester specifically designed for small and medium-sized hollow containers, such as empty PET bottles and personal care product bottles. This model features a linear, in-line production design. Using a pneumatic or servo-driven pressing mechanism at the top, it performs non-destructive airtightness testing on empty bottles as they pass along the conveyor belt in a matter of seconds. It is particularly well-suited for direct integration at the front end of blow molding machines, injection molding machines, or filling lines.

• Extremely compact footprint, plug-and-play: Featuring a single-column cantilever design, the equipment significantly reduces its footprint in both the front-to-back and side-to-side directions, making it ideal for production facilities with limited floor space and complex conveyor layouts.
• Precise low-pressure differential pressure detection: Suitable for thin-walled PET bottles, it provides lower and more stable detection pressure. When paired with a differential pressure sensor, it automatically detects minute deformations caused by uneven bottle wall thickness, preventing permanent expansion and deformation of thin-walled bottles during gas filling.
• High versatility and rapid changeover: Both the top and middle columns are equipped with handwheel adjustment mechanisms. When switching between bottle types of different heights or diameters, no complex tools are required; operators can simply turn the handwheels to reposition the mechanical height within 3-5 minutes.
• Fully Sealed, Error-Proof Sealing Fixture: The test head is equipped with a soft silicone sealing pad featuring self-centering functionality. Even when dealing with plastic bottles that have minor burrs or flash on the bottle neck, it ensures a tight seal without damaging the threads, thereby preventing false alarms caused by improper sealing.

• Cantilevered Integrated Control Panel: The touchscreen, emergency stop button, and pressure gauge are integrated into an angle-adjustable cantilevered control box, saving space while allowing operators to safely adjust process parameters from their position beside the conveyor belt.
• High-Precision Test Press-Down Module: The top features a vertical press-down mechanism combining dual guide rods and a cylinder, ensuring verticality and concentricity during the test head's descent and preventing lateral thrust on lightweight empty bottles.
• Side-Mounted Precision Air Tank/Filter: A small stainless steel precision air tank and air filter assembly is mounted externally on the lower-middle section of the machine body. This assembly provides secondary pressure stabilization and purification of the input compressed air, effectively filtering out trace amounts of moisture and oil from the air source to ensure the absolute accuracy of the leak detection pressure sensor's results.
• Robust Mobile Base: The base is constructed from thickened steel plate and features height-adjustable shock-absorbing feet and heavy-duty swivel casters, allowing the unit to be easily positioned between different blow molding machines or filling line outlets for integrated production.
