Heating adjustment device and glass thickness adjustment method

Abstract

The invention relates to the technical field of heating devices, and discloses a heating adjustment device and a glass thickness adjustment method. The heating adjustment device comprises a first insulating pipe section with a first internal channel, a second insulating pipe section with a second internal channel, an insulating structure with a through channel and an electric heating wire, wherein the insulating structure is arranged between the ends, close to each other, of the first insulating pipe section and the second insulating pipe section; the electric heating wire penetrates into the first internal channel and then enters the second internal channel through the through channel; and the electric heating wire penetrates out of the second internal channel and then is spirally wound on the second insulating pipe section in a return direction at a preset screw pitch to form a second heating section, and is arranged on the first insulating pipe section in the return direction; and the insulating structure is movable to allow the second insulating pipe section to be bent to a desired angle relative to the first insulating pipe section. The heating adjusting device can provide a good and stable heating radiation range so as to provide stable and reliable heating.

Description

Technical field[0001]The present invention relates to a heating device, such as a heating adjustment device for use in the production of a glass substrate, and in particular, to a heating adjustment device and a glass thickness adjustment method.Background technique[0002]In the field of glass substrate production, in the process of manufacturing the display substrate glass, the high-temperature glass fluid is different from the high temperature difference in the overflow surface of the overflow brick, resulting in a different viscosity of the local glass fluid due to the heat difference of the heating. There is a difference in transverse fluidity in the glass liquid, which in turn affects the molding thickness of the glass substrate. The glass liquid having a high temperature is small, due to the pull of the device, causing the glass substrate whose molded glass substrate is thinned, and the viscosity of low temperature is large, and the glass substrate below it will be thicker. The...

Problems solved by technology

[0004] However, there is a power attenuation phenomenon in the actual use of platinum hot air pipes, and the power of a single platinum hot air pipe is limited, so it can only be adjusted point-to-point, and the thickness adjustment effect is poor. In order to increase the thickness adjustment effect in production, often Multiple platinum hot air pipes should be installed on the left and right sides of the cooling mechanism. As the production time prolongs, the power of the platinum hot air pipes will decay. In order to stabilize the extremely poor thickness, it is necessary to continue to increase the power of the platinum hot air pipes. When the power is increased to the upper limit and the adjustment of the thickness range cannot be satisfied, the thickness adjustment effect will become worse, and the thickness curve will change, resulting in the fluctuation of the thickness range
