Preparation device for alkali-resistant glass balls and glass fibers

The invention discloses a preparation device for alkali-resistant glass balls and glass fibers, comprising a molten pool and a work pool, wherein the work pool is connected with a ball forming machine, the outlet of the work pool is connected with the inlet of the ball forming machine and a glass metal channel, and the glass metal channel is provided with a wire drawing crucible bushing. By adopting the invention, ball making and wire drawing can be carried out at the same time, and the uniform flow direction of glass metal is ensured simultaneously; and the fluctuation of the glass metal in the melting pool and the work pool is small, skin cracking does not occur on the surface of the glass balls, no intensive small bubbles generate in the glass balls, the uniformity is very excellent, the rejection rate is low, and the tensile strength and the elastic coefficient of the glass fibers are improved.
