Product Essence: Seamless End-of-Line Integration
Shanghai Guangzhi Automation’s Bag Closing Conveyor unifies bag sealing, inspection, and transfer in one robust system. Engineered for 10-50kg sacks (PP woven/paper/jute), it achieves 40 bags/minute with precision sewing or heat sealing (±0.5mm accuracy), ATEX-compliant dust containment, and zero-damage handling – critical for cement, grain, and chemical packaging.
Core Technology Highlights
1. Intelligent Sealing Options
Dual-Mode Closure:
Industrial Sewing Head: Triple-thread lockstitch (35 lb tensile)
Heat Sealing Bar: 0-300°C for laminated bags (10mm seal width)
Auto-Detect System: Laser scans bag material to switch modes
2. Precision Conveyance
Servo-Driven Belts: Speed sync ±0.1s with upstream fillers
Anti-Slip Control: Vacuum zones hold bags during sealing
Zero Misalignment: Edge guides with AI vision correction (±1mm)
3. Dust-Tight Containment
Enclosed Sealing Chamber: IP65-rated with HEPA filtration (99.97% @ 0.3μm)
Negative Pressure System: -15Pa dust capture at transfer points
ATEX Zone 21 Kit: Explosion-proof motors (Ex IIB T4)
