The dual-column screen changer in the meltblown fabric production line is a highly efficient and critical equipment configuration. Its distinctive feature lies in the dual-station dual-flow channel design, which enables simultaneous operation and alternating replacement of dual screens, thereby ensuring production continuity and stability. The hydraulic dual-column screen changer adopts a cylindrical filter screen structure, significantly increasing the filtration area to effectively remove impurities from the melt and prevent spinneret blockage. Meanwhile, the rigid sealing structure eliminates leakage issues, while optimized material introduction and air exhaust minimize pressure fluctuations during screen change processes. Additionally, this screen changer can be equipped with an automatic alarm monitoring system to ensure safe and stable system operation. Various specifications and materials can be selected according to production needs to meet different product and process requirements.

Technical Explanation:

In meltblown fabric production, the dual-column screen changer serves as a critical component that enables:

Continuous Production: Its dual-station design allows uninterrupted operation by alternating between two filter screens

Efficient Filtration: Cylindrical filter structure increases surface area for better impurity removal from molten polymer

Process Stability: Rigid sealing and optimized flow channels minimize pressure fluctuations during screen changes

Quality Assurance: Prevents nozzle blockage and ensures consistent fiber formation in the final meltblown fabric

Industry Context:

This equipment is particularly important in meltblown manufacturing due to:

High production speeds requiring frequent screen changes

Stringent quality standards for medical-grade filtration materials

Need for continuous operation in automated production lines
