A heating device for liquid crystal glass

Abstract

The invention provides a heating device of liquid crystal glass. The heating device comprises a heating device body, wherein the heating device body is arranged on an installation mechanism of an edgedrawing machine; the heating device body comprises a high-temperature electrode and a heating position adjusting mechanism; the heating position adjusting mechanism is arranged on the installation mechanism of the edge drawing machine; the high-temperature electrode is arranged on the heating position adjusting mechanism. The heating device has the advantages that by arranging the heating deviceand the heating position adjusting mechanism on the installation mechanism of the edge drawing machine, the glass sticking matter can be accurately melted at high temperature; the solid matter which is formed at low temperature at the end surface of an overflow brick is cleared; the production and use requirements are met.

Description

technical field [0001] The invention belongs to the manufacture of liquid crystal glass, in particular to a heating device for liquid crystal glass. Background technique [0002] In the process of liquid crystal glass manufacturing, the glass liquid is heated to the process temperature after the previous process, flows through the overflow brick to form a glass plate with a flat surface, uniform thickness, and a certain width, and then forms the substrate glass we need after forming and annealing . [0003] Such as figure 1 As shown, in the glass forming process, different heaters are distributed around the overflow brick 1 of the muffle furnace to control the space temperature, so as to satisfy the glass forming temperature distribution. However, due to the large size of the high-generation liquid crystal glass and the large volume of the overflow brick, the temperature around the brick body cannot be completely consistent. The temperature at the end surface of the hot e...
