Technical Overview

The Automatic Jumbo Bag Packing Machine represents cutting-edge Chinese packaging technology specifically engineered for hazardous and non-hazardous chemical materials.With a robust SUS304 stainless steel construction and explosion-proof certification (ATEX optional), this system achieves ±0.15% weighing accuracy for 500-2000kg FIBCs through its patented three-stage filling algorithm.The modular design integrates pre-treatment, filling, and post-processing units into a 15-meter production line footprint, capable of processing 25-30 metric tons per hour with minimal human intervention.

Core Specifications

Operational Protocol

Pre-Operation Checklist

Conduct pneumatic pressure test (0.5-0.8MPa) and emergency stop verification

Calibrate load cells using Class M1 test weights with 5-point verification

Install appropriate dust collection filters (HEPA ULPA for nano-powders)

Automated Filling Sequence

Bag Positioning: Laser-guided FIBC alignment with ±2mm tolerance

Multi-Stage Filling:

Primary feed at 2.5t/min (90% capacity)

Secondary precision feed at 200kg/min

Final micro-adjustment (±50g accuracy)

Containment Systems:

Double flap valve isolation

Negative pressure containment (5Pa vacuum)

Maintenance Regimen

Daily: Clean contact surfaces with chemical-neutral solvents

Weekly: Inspect auger wear (max 0.3mm clearance) and torque all fasteners

Monthly: Replace pneumatic filters and validate scale calibration

Annual: Overhaul servo motors and replace all wear plates

Troubleshooting Matrix

Critical Fault Resolution

• Material Bridging: Activate fluidization pads (0.2MPa air pulse) and increase hopper vibration amplitude

• Electrostatic Discharge: Verify grounding resistance (<4Ω) and install ionizing bars

• Weighing Drift: Isolate from plant vibrations and recalibrate with master weights

• Valve Leakage: Replace PTFE seals and adjust actuator pressure to 0.6MPa
