Glass fiber nozzle structure, bushing and production device

Abstract

The present application provides a glass fiber nozzle structure, bushing and production device. The glass fiber nozzle structure includes a nozzle body and a hole provided on the nozzle body. The hole includes an upper hole portion and a lower hole portion communicated with the upper hole portion and located below the upper hole portion. The lower hole portion has an elongated cross-section. A projection of the lower hole portion is located within a projection of the upper hole portion in a projection on a plane perpendicular to an axis line of the lower hole portion. A length and a width of the lower hole portion have a ratio of 5:1 to 12:1. The glass fiber nozzle of the present application has a simple structure and a long service cycle, and an aspect ratio of flat glass fibers produced by the nozzle structure is maintained between 2.7 and 4.2, thereby effectively improving performance of the flat glass fibers.
