Maotong Squeeze-Type Leak Detection Equipment for Bagged Products
Core Product Model: MT-DZ-XL-S1--01 (Inline Squeeze Detector)
Technical Principle:
Utilizing squeeze-belt detection technology, the system creates a compression zone between a flexible squeeze belt and a lower conveyor belt to continuously apply pressure to bagged products. Sensors mounted on the squeeze belt detect changes in internal bag pressure; a controller converts these readings into digital signals for analysis, thereby determining whether the product is leaking.
Key Performance Parameters:
• Detection Speed: Up to 180 bags/minute
• Detection Range: 0.08 – 0.5 MPa
• Detection Accuracy: Better than 0.02 MPa
• Rejection Rate: ≥ 99.99%
• Power Requirements: Single-phase AC 220V, 50Hz; Total Power: 250W
• Air Source Requirements: Compressed air, 4–8 Bar
• Equipment Dimensions: 1600mm × 700mm × 600mm (Width × Height × Depth)
• Equipment Weight: Approx. 80 kg
Comparative Advantages Over Traditional Detection Methods
| Detection Method | Maotong Automation Equipment | Traditional Manual Methods |
| Detection Efficiency | 180 bags/minute; fully automatic, continuous detection | Manual inspection (one by one); low efficiency |
| Detection Accuracy | Pressure sensor detection; accuracy of 0.02 MPa | Relies on human sensory judgment; highly subjective |
| Consistency | Standardized pressure control; stable and reliable results | Heavily influenced by operator experience |
| Applicability | Supports detection of both high-pressure and low-pressure products | Less effective on products made of thick, rigid materials |
| Data Recording | Real-time dynamic display of multiple sets of rejection data | No data recording; difficult to trace back results |
