Mechanical parameters

Mechanical configuration

I. Main Equipment of the Spunbond 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): 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. Filter (2 sets): A device used to hold filter elements, designed to remove impurities from the PP melt.

5. Metering pumps (2 sets): Devices used to meter the amount of PP melt. 
6. Spinning Box (2 sets): One of the key components of a melt‑spinning machine, the spinning box receives the polymer melt after it has passed through a filter. The melt is then distributed and thermally maintained within the box before being delivered to each spinning station for fiber formation. The box is a rectangular metal enclosure with an external insulation layer, housing the melt distribution manifold, pump mounting, and spinneret assembly. It also includes a fixture for securing the spinneret plate. 
7. Single‑unit suction system (2 sets): Ensures stable suction airflow and prevents any adverse effects on the tow. 
8. Aluminum cooling air boxes (2 sets): Low-temperature air is blown onto the aluminum surface at a high velocity to achieve cooling. 
9. Drawing units (2 sets): tempered glass; stainless steel construction. These units stretch the filament bundle, 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: ≤ 350 m/min 
12. Hot rolling mill (1 unit): Heating method: oil heating/thermal oil

13. Automatic winding machine (1 unit): Speed: ≤ 350 m/min 
14. Mesh curtains (2 sets): Serve to support the filament bundle as it moves toward the nip roller for bonding. 
15. PLC Control Cabinet: The control cabinet serves to distribute electrical power and manage the power supply to the equipment. 
16. Slitting machine (1 unit): Slices large rolls of fabric into specified dimensions according to customer requirements, meeting the customer’s specifications for product length, width, and roll weight. 
II. Main Equipment of the Meltblown System (1 set in total) 
1. Vacuum feeder (1 set): a device used to suction and convey raw materials. 
2. Screw extruder (1 set): The drive motor is a Siemens AC variable-frequency motor.

3. Filters (1 set): Available types include rod-type and plate-type.

4. Metering pump (1 set): A device used to meter the amount of PP melt.

5. Meltblown die (1 set): 
6. Nozzle moving device (1 set): Integrated lifting mechanism 
7. Air heater (1 unit): Material: Stainless steel 
8. High-pressure blower (1 unit): 
9. Suction Fan – Meltblown (1 unit): Equipped with a Siemens AC variable-frequency motor. 
10. PLC control cabinet (1 set): Siemens model 
11. Mesh Curtain: Type: Seamless 
 

Application scenarios

SMS Three-Component Spunbond/Meltblown/Spunbond Production Line 
A high‑density meltblown fiber layer is interposed between two spunbond layers, creating a “spunbond–meltblown–spunbond” sandwich structure. This architecture imparts the product with excellent hydrostatic pressure resistance, high bacterial particle filtration efficiency, and good breathability. 
Detailed application scenarios: 
Key barrier for medical protection: Disposable surgical gowns, surgical drapes, isolation gowns, surgical pack cloths, and sterilization wrap cloths 
Medical consumables: Surgical drape, surgical underpad, antiseptic bandage 
Industrial Safety Protection: Dust-proof workwear, paint-spraying protective clothing 
Eisai Barrier Layer: Barrier-reinforced layer and side-leakage‑preventing edge for composite use in the leak‑proof backsheet of disposable diapers 
Function Processing Description: SMS products that have undergone “three‑resistance” treatment—resistance to alcohol, blood, and oil—as well as antistatic processing, can meet higher‑grade medical protective standards.
