Feeding system suitable for glass substrate production line

Abstract

A feeding system suitable for a glass substrate production line comprises a hopper, a spiral feeding pipeline and a moving trolley. A feeding port in the upper end of the hopper is in butt joint with a stock bin of the glass substrate production line, a discharging port in the lower end of the hopper is communicated with an inlet of the spiral feeding pipeline, three layers of heat insulation protection structures are arranged outside the hopper, the first layer of heat insulation protection structure is a vacuum protection sleeve, and the vacuum protection sleeve is installed on the side wall of the hopper. The second layer of heat insulation protection structure is heat insulation cotton, the heat insulation cotton is coated outside the vacuum sheath, and the third layer of heat insulation protection structure is a heat insulation plate arranged between the hopper and a kiln of a glass substrate production line; the spiral feeding pipeline is arranged on the moving trolley, the outlet end of the spiral feeding pipeline is connected with an inlet of the kiln, and a cooling water jacket is arranged outside the spiral feeding pipeline. The problems that in the prior art, batch is heated to crystallize on the wall of the hopper, and the hopper is difficult to replace are solved, and the purposes of guaranteeing the product quality and reducing the production cost are achieved.

Description

technical field [0001] The invention relates to a glass substrate production line feeding system, in particular to a movable heat-insulating feeding system suitable for a high-generation glass substrate production line. Background technique [0002] With the development of information display technology, high-generation glass substrates have become the mainstream products of substrate glass manufacturers, and in order to realize the excellent performance of high-generation glass substrates in ultra-thin, high-definition, curved surface, color gamut, contrast, etc., the production line Configuration puts forward higher requirements. [0003] In the glass substrate production line, the moisture and temperature of the batch materials in the hopper must be controlled within a reasonable range to avoid adverse effects on product quality. Normally, the silo of the glass substrate production line is connected to the kiln through a hopper and a screw feeding pipe. However, during t...

AI Technical Summary

Problems solved by technology

Normally, the silo of the glass substrate production line is connected to the kiln through a hopper and a screw feeding pipe. However, during the heating process of the kiln, it will cause heat conduction to the hopper, causing the moisture in the batch material close to the hopper wall to evaporate, resulting in The inner wall of the hopper is heated and crystallized, which not only affects the proportioning accuracy of the raw materials, resulting in uneven mixing, but also causes quality defects such as air bubbles and streak fluctuations in the subsequent melting process; To replace and overhaul it, because the hopper and silo in the feeding system in the prior art are fixed assembly structures, the disassembly process steps are cumbersome, and the feeding system and even the entire production line need to be stopped, which greatly increases the production cost
