[0002] During the production of polyester needle-punched nonwoven fabric, static electricity is easily generated on the surface of the nonwoven fabric due to friction and separation between fibers. The presence of static electricity not only attracts dust and other impurities, affecting the appearance and quality of the product, but may also cause discharge phenomena during subsequent processing, posing a hazard to operators and equipment.

[0003] Some existing static elimination devices have certain limitations in their structural design. When the width and thickness of polyester needle-punched nonwoven fabric are different, the static elimination device cannot be flexibly adjusted according to the different specifications of polyester needle-punched nonwoven fabric, resulting in poor static elimination effect and difficulty in meeting diverse production needs. Therefore, we propose a static elimination device for polyester needle-punched nonwoven fabric to solve the above problems. Utility Model Content
