The invention relates to the technical field of
glass manufacturing, and discloses a high-efficiency conveying mechanism for annealing
processing of a glass product. The mechanism comprises a box body, wherein a material clamping cavity is formed in the middle part of the box body, a rotating frame is movably connected to the middle part of the material clamping cavity, and a lower fixing seat isfixedly connected to one side of the rotating frame. According to the invention, an automatic turnover mechanism is additionally arranged; when a to-be-treated
glass tube is in a heating stage, a heatpreservation stage and a rapid cooling stage,
gas passing through a
gas pressure cavity has pressure changes due to different temperatures, and the
gas pressure cavity is subjected to pressure reliefand negative pressure filling through gas outlet holes with small diameters, so an upper
ratchet plate and a lower
ratchet plate extend or retract under the action of the pressure changes; a rotatinggear rotates through a
ratchet end, so a supporting frame drives the to-be-treated
glass tube to turn over; and thus, the
glass tube can be automatically turned over during temperature rise, the glass tube is heated uniformly, and can be turned over multiple times in the heat preservation stage and the rapid cooling stage, and the upper side and the lower side of the glass tube are heated more uniformly.
