Why the PE Bottle Squeeze Leak Detection Machine Fits 600 Bottle Lines

2026/11/13 14:16

Fast bottling lines have little tolerance for uncertainty. When a leaking container reaches downstream packaging, the cost is rarely just a single unit—it can mean cleanup, line interruptions, and quality complaints. The PE Bottle Squeeze Leak Detection Machine is positioned as an inline solution for pressure and leak inspection on specified gas-containing containers, combining belt squeeze detection, a dual-sensor pressure comparison approach, and automatic rejection.

What the machine is designed to do

Fast bottling lines have little tolerance for uncertainty. When a leaking container reaches downstream packaging, the cost is rarely just a single unit—it can mean cleanup, line interruptions, and quality complaints. The PE Bottle Squeeze Leak Detection Machine is positioned as an inline solution for pressure and leak inspection on specified gas-containing containers, combining belt squeeze detection, a dual-sensor pressure comparison approach, and automatic rejection.

Inline bottle leak detector on production line


In a single pass on the conveyor, the PE Bottle Squeeze Leak Detection Machine performs:

•Pressure detection
•Leak detection
•Automatic rejection of non-conforming products based on user-defined criteria

The machine is described as using a contact-based online detection method that reflects internal pressure characteristics during inspection, supported by a proprietary DSP digital signal processing algorithm. For production environments that start and stop, it also includes adaptive speed tracking, stopping when the production line stops to help prevent bottle jamming or damage.

For buyers comparing solutions, the key takeaway is practical: the PE Bottle Squeeze Leak Detection Machine is built for inline inspection at speed, with a rejector and on-screen result presentation via a human-machine interface.

Where it fits in packaging operations

The stated applicable inspection objects include:

•Aluminum cans filled with liquid nitrogen
•PE/PP plastic bottles containing gas or steam
•Other gas-containing containers (excluding CO2)

This scope matters during procurement. If your product category falls outside these specified objects—especially if it involves CO2—confirm compatibility before line integration.

When combined with upstream and downstream checkpoints, the PE Bottle Squeeze Leak Detection Machine can sit alongside other inline controls such as a Code Inspection Machine or a Can Pressure Tester, depending on the line’s overall quality plan.

How belt squeeze and dual-sensor comparison works

The PE Bottle Squeeze Leak Detection Machine includes an extrusion (squeeze) section and two sensor positions described as S1 and S2. The working sequence is outlined as follows:

1.A positioning sensor detects the arriving product and records its ID and encoder signal via the control unit.
2.A guide mechanism at the front pre-squeezes the bottle to create a specific internal pressure condition.
3.Sensor S1 captures the initial pressure signal (Pressure 1).
4.Sensor S2 captures the downstream pressure signal (Pressure 2).
5.The signal processing board analyzes data (with the DSP algorithm) and transmits results to the interface and control unit.
6.When a rejection signal is issued, the rejector removes the non-conforming product.

Operationally, the comparison between Pressure 1 and Pressure 2 is used to determine whether pressure has released during the controlled squeeze section—an indicator used for leak discrimination in this equipment’s stated principle.

Key performance parameters buyers typically check first

The specification set published for the PE Bottle Squeeze Leak Detection Machine includes the following parameters.

ItemParameter
Maximum inspection speedExceeds 600 bottles/minute
Detection range0.08 to 0.5 MPa
AccuracyBetter than 0.02 MPa
Rejection rate≥99.99%
False reject rate≤0.03%
Power supply / consumptionSingle-phase AC 220V, 50Hz / 250W
Compressed air4–8 bar
Operating environment0–50°C, 10%–80% RH
Interface and functionsHuman-machine interface, dynamic rejection data display, impact light alarm, continuous rejection shutdown, 24-hour remote assistance, Chinese language menu

Note the stated condition that excessive vertical vibration of the conveyor chain can affect accuracy—this is one of the most practical details to evaluate during site review.

Installation and operating checklist for stable results

For stable inspection with the PE Bottle Squeeze Leak Detection Machine, the published installation guidance emphasizes line geometry, alignment, and utilities.

Conveyor and alignment

•Use a straight section of the production line of 1.5–2 meters for installation.
•Keep the equipment horizontal.
•Ensure the clamping conveyor belt is parallel to the product conveyor belt.

Utilities and pre-start checks

•Confirm cables are secure and verify the grounding wire of the control box before powering on.
•Connect to AC 220V, 50Hz power.
•Supply compressed air at 4–8 bar.

Process conditions that influence consistency

•For reliable results, it is recommended to test products after cooling or on a single-row conveyor where product temperature is uniform.
•Rapid temperature changes and uneven bottle wall thickness are listed as factors that can influence inspection results and may lead to false rejections.
