Embodiment 1
[0056] Please refer to figure 1 and figure 2 , this embodiment provides a control device 100 and a substrate glass production line 200 using the control device 100, the structure of the control device 100 is image 3 and Figure 4 shown in .
[0057] combine figure 1 and figure 2 , figure 1 The substrate glass production line 200 shown in includes a melting furnace 201, a first connecting pipe 202, a refining device 203, a second connecting pipe 204, a stirring device 205, a connecting device 206, a conveying device 207, a connecting device 208, an overflow device 209 , edge pulling device 210 , traction mechanism 211 and regulating device 100 .
[0058] In this embodiment, the substrate glass is first melted into molten glass in a high-temperature melting furnace 201 according to a certain proportion of glass ingredients, and then made into a glass ribbon 212 through a forming process system, and then drawn into a substrate by a traction mechanism 211 Glass.

Embodiment 2
[0102] This embodiment provides a control method, which uses the above-mentioned control device 100, and the method includes:
[0103] At least one of the first regulating member 10 , the second regulating member 20 and the third regulating member 30 is controlled to make the guide wheel 40 contact the position to be contacted with the glass ribbon 212 and guide the glass ribbon 212 to flow.
[0104]For the structure of the regulating device 100, reference may be made to Embodiment 1.
[0105] Please refer to Figure 8 , Figure 8 The illustrated substrate glass 300 is subject to natural warping. Therefore, the guide wheels 40 positioned on both sides of the glass ribbon 212 do not contact the glass ribbon 212, only the edge pulling device 210 and the traction mechanism 211 are in contact with the glass ribbon 212, so that the glass ribbon 212 is in contact with the glass ribbon 212. Figure 9 state in .
[0106] Please refer to Figure 10 , Figure 10 The substrate glas...

Abstract
In embodiments, the invention provides a regulation and control device, a substrate glass production line, and a regulation and control method and relates to the technical field of production of substrate glass. The regulation and control device includes a frame, a first regulator, a second regulator, a third regulator, and a guiding wheel, wherein the first regulator is in sliding connection withthe frame in a first predetermined direction; the second regulator is in sliding connection with the first regulator in a second predetermined direction; the third regulator is in sliding connectionwith the second regulator in a third predetermined direction; any two among the first, second and third predetermined directions are orthogonal to each other; the guiding wheel is rotatably connectedto the third regulator and is contacted with a glass tape. By means of the first, second and third regulators, the contact position between the guiding wheel and the glass tape can be adjusted, so that the guiding wheel can move to and be contacted to an area that needs contact. The guiding wheel is pressed against and guides the glass tape to flow, so that flowing status of the glass tape is stabilized, and quality of the produced substrate glass is improved.
Description
technical field [0001] The invention relates to the technical field of substrate glass production, in particular to a control device, a substrate glass production line and a control method. Background technique [0002] The production methods of substrate glass mainly include float method, slit downdraw method and overflow downdraw method. The overflow pull-down method is to send the molten glass into the U-shaped groove on the upper part of the overflow brick. After the overflow groove is full, the glass liquid will naturally overflow from both sides of the top of the groove and gather together at the root of the U-shaped overflow device. Form a glass ribbon, continue to fall under the action of gravity, and then be drawn into a substrate glass by the traction of the traction roller. During the production process, the outer surface of the molten glass is not in contact with the overflow brick, and has good flatness and smoothness, which is a kind of high-quality substrate ...
