| Designed to streamline industrial filter bag shipping and storage, this automated folding machine reduces package volume by 60-70% while preserving bag integrity. It processes 15-20 bags per minute with ±2mm folding accuracy, supports Z-fold/accordion fold/roll fold modes, and cuts packaging labor costs by 75% compared to manual operations. | |||||||||
The SY-4331 Filter Bag Folding Machine, also referred to as the Filter Bag Packaging Folding System and Automated Bag Compacting Machine, is engineered to address logistical challenges of packing large industrial filter bags for storage and shipping. Unlike manual folding, which causes inconsistent compaction and potential product damage, this automated system performs precise folding and compacting operations while preserving bag integrity. It reduces package volume by 60-70% compared to unfolded bags, supporting commercial procurement teams aiming to optimize supply chain efficiency. The machine handles folded or pleated filter bags with lengths of 1-6 meters and diameters of 120-300mm, operating at 15-20 bags per minute with a repeatable folding accuracy of ±2mm.
The machine features multi-stage programmable folding sequences, including Z-fold, accordion fold, and roll fold, which adapt to different bag types. Servo-driven arms ensure uniform creasing across all folds. A pneumatic compression plate with adjustable force ranging from 5-30 kg compacts folded bags to a consistent density of 0.3-0.5 g/cm³, enabling uniform box filling. Soft-touch silicone rollers and low-friction guides prevent fiber shedding and abrasion, which is critical for handling delicate filter media such as PTFE and glass fiber used in HEPA-grade and anti-static applications.

For pharmaceutical filtration, the machine folds sterile polyester bags into compact packages while maintaining ISO 5 cleanroom standards (≤10 particles/ft³ ≥0.5μm). In semiconductor manufacturing, its anti-static handling system prevents electrostatic discharge (ESD) damage when packaging PTFE bags for chemical processing, protecting sensitive production components.
For HVAC distribution, the machine compacts large pleated air filter bags, reducing transport volume by 65% and lowering freight costs by 0.20-0.50 per bag. It also meets UN 3291 requirements for preparing PTFE-coated glass fiber bags used in hazardous waste filtration, preventing fiber release during transportation.
The SY-4331 reduces packaging labor costs by 75%, as one operator can manage 20 bags per minute compared to 2-3 bags per minute per manual worker. It processes up to 900 bags per 8-hour shift, with changeover between different bag sizes taking less than 5 minutes using pre-stored recipes for up to 50 configurations.
Product damage during packaging decreases from 8% to less than 1%, eliminating costly rework and customer returns. The 60-70% volume reduction cuts warehouse storage requirements by 50% and shipping costs by 30-40%. Uniform folding ensures standardized package dimensions, increasing palletization efficiency to 40-50 bags per pallet compared to 15-20 bags for manually folded packages.
Engineers analyze bag dimensions, material stiffness, and pleat structure to develop custom folding sequences and compression settings. Optional configurations include vacuum assist for lightweight media, heated rollers for memory-fold materials, and custom exit conveyors for integration with existing packaging lines.
Samples undergo transportation simulation testing per ASTM D4169 to verify bag integrity after folding and shipping. Additional support includes operator training on recipe management and maintenance, remote monitoring capability for performance optimization, and integration with ERP systems for production tracking.
The machine processes folded or pleated filter bags made from various media, including polyester, PTFE, and glass fiber. It accommodates bags with lengths of 1-6m (extendable to 10m) and diameters of 120-300mm.
The machine is equipped with a vision system that inspects folded dimensions and detects damage. Non-conforming bags are automatically rejected to maintain shipment quality.
Yes, the output conveyor connects to automatic bagging machines or manual packing stations. Optional barcode scanning is available for product traceability.
All custom configurations undergo transportation simulation testing per ASTM D4169 to verify bag integrity under real-world shipping conditions.
