Mechanical parameters

Mechanical configuration

I. Main Equipment of the Spunbond System (3 Sets in Total)

1. Vacuum material feeder (3 units): a device used to suction and convey raw materials. 

2. Screw extruders (3 sets): Equipped with electrically heated cast-aluminum heating bands to ensure proper melting of the raw materials.

3. Return-material screw: It is an automatic feeding device. 
4. Filters (3 sets): Devices used to hold filter elements, designed to remove impurities from the PP melt.

5. Metering pumps (3 sets): Devices used to meter the flow rate of PP melt. 
6. Spinneret Housing (3 sets): One of the key components of a melt-spinning machine, the spinneret housing receives the polymer melt after it has passed through a filter. The melt is then distributed and kept at a controlled temperature before being delivered to each spinning position for fiber formation. The housing is a rectangular metal enclosure with an external insulation layer, containing melt distribution manifolds, pump mounts, and spinneret assemblies. It also incorporates a fixture for securing the spinneret plate. 
7. Single-unit suction system (3 sets): Ensures stable suction airflow and prevents any adverse effects on the tow. 
8. Aluminum cooling air boxes (3 sets): Low-temperature air is blown onto the aluminum surface at a high velocity to achieve cooling. 
9. Drawing units (3 sets): tempered glass; stainless steel construction. These units stretch the filament tow, reducing its diameter and ensuring greater uniformity before it enters the web-forming machine. 
10. Insulation materials for oil pipelines: They feature a low thermal conductivity and excellent insulation performance, while also offering advantages such as flame retardancy, superior thermal stability, light weight, heat resistance, and strong resistance to chemical corrosion.

11. Web-forming machine (1 unit): Speed: ≤ 450 m/min 
12. Hot rolling mill (1 unit): Heating method: oil heating/thermal oil

13. Automatic winding machine (1 unit): Speed: ≤450 m/min 
14. Mesh curtains (2 sets): Serve to support the filament bundle as it moves toward the nip roller for bonding.

15. S-Roller Hot Rolling Mill (including oil furnace) (1 unit): Heating method: thermal oil/oil heating

16. PLC Control Cabinet: The control cabinet serves to distribute electrical power and manage the power supply to the equipment. 
17. Slitting machine (1 unit): Slices large rolls of fabric into specified widths and lengths according to customer requirements, meeting their specifications for product length, width, and roll weight. 

II. Main Equipment of the Meltblown System (2 Sets in Total) 
1. Vacuum material feeder (2 sets): a device used to suction and convey raw materials. 
2. Screw extruders (2 sets): The drive motors are Siemens AC variable-frequency motors.

3. Filters (2 sets): Available types include rod-type and plate-type.

4. Metering pumps (2 sets): Devices used to meter the amount of PP melt.

5. Meltblown die (2 sets): 
6. Nozzle-moving mechanism (2 sets): integrated lifting and lowering

7. Air heaters (2 units): Material: Stainless steel 
8. High-pressure blowers (2 units): 
9. Suction Fans – Meltblown (2 units): Motors are Siemens AC variable-frequency motors. 
10. PLC Control Cabinet (1 set): Siemens model 
11. Mesh Curtain: Type: Seamless

VI. SSMMS Five-Head Meltblown Composite Production Line 
(Spunbond/Spunbond/Meltblown/Meltblown/Spunbond Line) 
By integrating the exceptional physical strength of two spunbond layers with the ultra‑high barrier performance of two meltblown layers, this product can stably deliver high hydrostatic pressure resistance and superior tensile strength, with all key performance metrics at the industry’s highest level.

Detailed application scenarios: 
Top-tier medical protective barrier: Level 4 surgical gowns, drapes for complex surgical packs, sterile pack wraps, and high‑level protective garments. 
High-end medical composite base fabric: An integrated top‑and‑bottom layer material for ultra‑premium incontinence products for infants and adults, delivering a three‑in‑one performance of softness, barrier protection, and breathability. 
Innovation in Specialized Protection: High-performance protective products treated with “three‑resistance” technology and high hydrostatic pressure, covering diverse applications such as maternal and infant care and medical protection. 
High hydrostatic pressure applications: Professional protective applications that must meet stringent impermeability standards.
