High-efficiency conveying mechanism for annealing processing of glass product

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of glass manufacturing, in particular to a high-efficiency annealing processing conveying mechanism for glass products. Background technique [0002] After glass products are formed at high temperature, different degrees of thermal stress will be generated during the cooling process due to different cooling rates, and these unevenly distributed thermal stresses will reduce the mechanical strength and thermal stability of the product, and have a negative effect on the glass. Product expansion, density, optical constants, etc. are all affected, causing glass products to be deformed or broken, which affects the production efficiency of glass products. Therefore, it is necessary to place the glass in the annealing furnace for a long enough time to pass through the annealing temperature range or above. Cool down at a slow rate so that permanent and temporary stresses beyond the permissible range are no longer gen...
