Problems solved by technology

[0002] Ultrafine glass fiber products are made of molten glass fiberized by centrifugal process, sprayed with thermosetting resin support filamentary material, and then processed by thermosetting raw materials. During the production process, the centrifuge is used to produce ultrafine glass The main machine for fiber products, which mainly relies on the centrifugal disc to throw out the molten raw materials and then draws them to form ultra-fine glass fibers. The existing centrifuge drawing mainly relies on the drawing wind disc, and the drawing tuyere is set on the drawing wind disc. The cold air is blown out through the stretching tuyeres to generate tension and cool the hot glass fiber strands, making the glass fiber strands thinner and shaped. The glass fiber strands produced in this way are in a straight line, so that the formed glass fiber wool The gaps between glass fiber filaments are small, and the thermal insulation performance and elasticity are poor

Abstract

The invention relates to a stretching air disc for a centrifugal machine. The stretching air disc comprises a stretching air disc body, two rows of annular 360-degree air outlets, circular holes and square openings are formed in the bottom face of the stretching air disc body, namely stretching air openings are formed, and air inlets communicated with the stretching air openings are formed in the stretching air disc. A spring piece can be arranged on the outer side or the inner side of the annular hole of the stretching air opening. According to the stretching air disc for the centrifugal machine, when air is discharged from the stretching air port, the spring pieces and airflow rub each other, so that the spring pieces vibrate to generate vibration waves, and the vibration waves are transmitted to the glass fiber filaments along with the airflow, so that the glass fiber filaments vibrate along with the vibration waves to generate the glass fiber filaments in corresponding shapes; therefore, gaps between adjacent glass fibers in the manufactured glass fiber cotton are larger, the glass fiber cotton is more fluffy, the tension between the fibers is stronger, and the thermal insulation performance and the elasticity are better.
