Embodiment Construction

[0031] The structure and control method of the present invention will be further described in detail with reference to the accompanying drawings.

[0032] Refer to attached Figure 1-5 , to realize a control system for stabilizing the quality of flat glass of the present invention, including several groups of pulling roller assemblies that apply traction force to the glass ribbon 7 to form flat glass, the pulling roller assemblies are short roller assemblies; the several groups of pulling roller assemblies are two The two pairs form multiple pairs of traction roller assemblies, and the opposite two sets of traction roller assemblies are located on both sides of the glass ribbon 7 in the width direction, and are respectively in contact with a certain end of the glass ribbon 7 in the width direction. The roller assembly is used to provide downward force to the glass ribbon 7; multiple pairs of traction roller assemblies are arranged at intervals along the flow direction of the g...

Abstract

The invention relates to a control system and a control method for sheet glass quality stability. The control system comprises a plurality of groups of short roller traction roller assemblies for applying traction force to a glass tape, a horizontal position adjusting device, an angle adjusting device, a speed adjusting device and a clamping force adjusting device. The control method mainly comprises the step of adjusting the horizontal positions, angles and speeds of the traction roller assemblies and clamping force for the glass belt. Due to the fact that the technical scheme for the short roller traction roller assemblies and combination adjusted control system parameters is adopted, the angles, horizontal and vertical positions and rotating speeds of roller components with the glass belt and the clamping force for the glass belt can be adjusted independently in the process that the glass belt is manufactured into sheet glass, the opportunity of controlling the shape and size of C shape is increased, and the quality of the finished product can be improved. The control system has the characteristics of reasonable structure, convenient implementation and good effect for stabilizing the quality of the finished product.

Description

technical field [0001] The invention relates to the field of flat glass manufacturing, in particular to a flat glass quality stabilization control system and a control method thereof. Background technique [0002] At present, the methods for producing substrate glass for LCD screens mainly include overflow down-draw method, float method, and slot-up method. In the overflow down-draw method or similar glass manufacturing process, the function of the traction roller assembly is to apply a vertical traction force to the glass ribbon, so that the glass ribbon can be made into the substrate glass for LCD screen through related processes. The overflow down-draw method is to flow the molten glass into the U-shaped overflow tank. When the overflow tank is filled with glass liquid, it will naturally overflow and flow from both sides of the overflow tank, and gather together at the root of the U-shaped overflow device to form a glass ribbon. , continues to fall under the action of gr...
