High-Speed Industrial Filter Bag Folder

Alternative Names and Product Introduction

Referred to as Automated Filter Bag Folding System and High-Precision Bag Pleating Machine, this advanced equipment revolutionizes filter bag manufacturing by automating the labor-intensive folding process. Designed to handle cylindrical and flat filter bags made from diverse materials (polyester, PTFE, aramid), the machine produces consistent folds, pleats, and creases that are critical for maximizing filter surface area and ensuring uniform airflow.

With a folding speed of 30–50 bags per minute (depending on size) and positional accuracy of ±1mm, this system outperforms manual folding by 5–8x while eliminating dimensional variations. Its adaptive folding mechanism adjusts to material thickness (300–1200g/m²) and stiffness, making it suitable for both flexible polyester and rigid glass fiber media used in power generation, cement, and pharmaceutical filtration.

Features

Folding Mechanism

• Precision Actuators: Servo-driven folding arms with 0.1mm positional resolution create consistent pleat heights (20–50mm) and fold angles (90°–180°) as programmed.

• Material Handling: Vacuum-assisted feeding system prevents material distortion, with adjustable grippers to accommodate bag diameters from 120mm to 300mm.

• Programmability: 100+ recipe storage for different bag configurations, with touchscreen interface (15-inch HMI) for easy parameter adjustment (pleat count, depth, spacing).

Operational Specifications

• Throughput: Processes up to 2,500 standard 1-meter bags per 8-hour shift, with quick changeover (<10 minutes) between bag types.

• Compatibility: Handles both sewn and welded bags, with optional pleat scoring for rigid materials to prevent fiber breakage.

• Quality Inspection: Integrated vision system (Keyence CV-X) checks fold uniformity, rejecting out-of-tolerance bags with <0.1% false rejection rate.

Applications

This High-Speed Folder is critical in manufacturing filter bags for performance-critical applications:

• HVAC Filtration: Creating pleated polyester bags with 40mm pleat height for commercial air handling units, increasing surface area by 300% vs. flat bags.

• Cement Plant Filters: Folding abrasion-resistant PTFE bags with reinforced fold points, ensuring uniform dust cake formation during pulse-jet cleaning.

• Pharmaceutical Filtration: Producing sterile pleated bags with 20mm pleats for API manufacturing, meeting ISO 8 cleanroom standards (≤100 particles/ft³ ≥0.5μm).

• Power Plant Filters: Folding large-diameter (300mm) aramid bags for coal-fired boiler dust collection, with precise fold spacing to optimize airflow distribution.

Advantages

Compared to manual folding and semi-automatic systems, this machine delivers significant benefits:

• Productivity Gain: 500% increase in folding output vs. manual labor, reducing per-unit labor costs by 0.75–1.50 per bag.

• Surface Area Optimization: Consistent pleating increases effective filtration area by 200–400%, extending bag service life by 30–50%.

• Process Consistency: Dimensional variation reduced from ±5mm (manual) to ±1mm (automated), improving baghouse airflow uniformity.

• Labor Reduction: One operator can manage the folding system vs. 4–6 workers for manual folding, freeing labor for higher-value tasks.

Customization Process

Our folder customization ensures seamless integration with specific production requirements:

• Bag Analysis: Engineers evaluate bag dimensions, material properties, and pleat specifications to design custom folding tooling.

• Machine Configuration: Options include single-fold, multi-fold, and pleating modules, with custom grippers for non-standard bag shapes.

• Integration Support: Can be connected to upstream sewing/welding lines and downstream packaging systems via conveyor integration and PLC synchronization.

• Validation Testing: Samples undergo dimensional accuracy checks and airflow testing to verify that folded bags meet performance specifications.

• Training Package: Includes 3 days of on-site training for operators and maintenance staff, with detailed SOPs and troubleshooting guides.
