AI Technical Summary
Existing spinneret cleaning methods are cumbersome to operate, inconvenient to replace blades, and lack an integrated oil supply system, resulting in incomplete cleaning, severe wear, and affecting the quality of chemical fiber products and production efficiency.
The scraper head adopts a wedge-angle quick-change structure and a pneumatically driven design, combined with an oil supply system, to achieve rapid blade replacement and active lubrication. Cleaning and lubrication are carried out synchronously through pneumatic drive.
It improves the thoroughness and efficiency of spinneret cleaning, reduces equipment wear, extends service life, prevents spinneret deformation caused by localized overheating, and meets the high-efficiency maintenance needs of chemical fiber production.
