X-Ray Level Inspection Machine

I. Project Overview

Project Title: Liquid Level Detection System

Project Scope: Online detection of product liquid levels with precise rejection of non-conforming containers.

Maximum Capacity: Up to 72,000 bottles/cans per hour (high-end model).

Applicable Container Materials: Aluminum, tinplate, PE/PET/PP plastics, ceramics, glass, and other common packaging materials.

Product Specifications: Volume range 200–2000 ml; diameter 30–90 mm; height 50–200 mm.

Equipment Model: MT-HFX-06.

II. Environmental Conditions

Applicable Altitude: 5–3000 m above sea level

Ambient Temperature Range: 5°C–40°C

Relative Humidity: 50%–65% RH

Factory Requirements: Floor flatness, load-bearing capacity, and other infrastructure conditions must comply with relevant national standards to ensure proper equipment operation.

Storage Conditions: After delivery, equipment and parts must be stored in compliance with national standards. During storage, appropriate lubrication and maintenance should be performed to prevent surface damage or deformation that may affect subsequent installation, commissioning, and operation.

III. Production Requirements

Power Supply: 220V, 50Hz, single-phase (provided by customer; special voltage requirements must be notified in advance, which may affect equipment configuration, delivery time, and pricing).

Total Power Consumption: Approx. 1.0 kW

Control Voltage: 24 VDC

Compressed Air: 4–12 Pa (customer to provide connection pipeline from air source to main equipment unit)

IV. Equipment Introduction

1. Installation Plan

Location: Installed after the filling machine, either before or after the inkjet printer.

Requirements: Must be mounted on a single-row conveyor chain with at least 2 m of straight length at the installation site.

Timeline: Installation to be completed within 24 hours.

Track Adjustment: A guardrail opening (≤15 cm) should be cut in the straight chain section to allow defective containers to be discharged by the rejector.

System Composition: The equipment is mainly composed of an inspection unit, rejection unit, power distribution cabinet, HMI, electronic modules, and mechanical assemblies.

Rejected Container Collection: It is recommended that the purchaser install a rigid box to collect defective containers at the rejection point.

2. Inspection Functions

High liquid level detection (auxiliary)

Low liquid level detection (standard)

3. Detection Principle

The system operates on the X-ray penetration principle. Containers with different liquid levels produce distinct projections at the receiving end, resulting in measurable numerical differences. These signals are compared against user-defined standard parameters. Products identified as defective are automatically removed by the rejection system.

4. Key Features

Non-contact, online inspection with no damage to containers.

Bottle counting performed by an encoder on the synchronous motor ensures rejection accuracy is not affected by line stoppages or speed changes.

Adaptive to varying production line speeds for dynamic inspection.

Independent inspection and control cabinets minimize electromagnetic interference, ensuring stable operation.

Stainless steel housing with sealed design, resistant to fog and water droplets, suitable for harsh environments.

Automatic shutdown of X-ray emission during idle operation.

Hardware-based circuitry with embedded operating system ensures long-term stability.

Integrated audible and visual alarms with automatic rejection of defective containers.

5. Technical Specifications

Conveyor Speed: ≤1.6 m/s

Container Diameter: 20–120 mm (device model selection depends on material density and size)
