Example 1

Referring to fig. 1 and 2, the present embodiment provides a conditioning device 100 and a substrate glass production line 200 using the conditioning device 100, and the structure of the conditioning device 100 is shown in fig. 3 and 4.

Referring to fig. 1 and 2, a substrate glass production line 200 shown in fig. 1 includes a melting furnace 201, a first connecting pipe 202, a refining device 203, a second connecting pipe 204, a stirring device 205, a communication device 206, a conveying device 207, a connecting device 208, an overflow device 209, an edge-drawing device 210, a drawing mechanism 211, and a regulating device 100, which are connected in this order.

In this embodiment, the substrate glass is prepared by melting glass ingredients into molten glass in a high-temperature melting furnace 201 according to a certain formula ratio, forming a glass ribbon 212 through a forming process system, and drawing the glass ribbon into the substrate glass through a drawing mechanism 211.

Specifically, in this embodiment, the "overflow downdraw method" is used to manufacture the substrate glass.

The glass batch is put into the melting furnace 201 for high-temperature melting, is conveyed to the refining device 203 through the first connecting pipe 202 to enable molten glass to be high-temperature and clarified, is conveyed to the stirring device 205 through the second connecting pipe 204 to enable the temperature and chemical components of the molten glass to be fully homogenized, is conveyed to the conveying device 207 through the communicating device 206, and flows into the overflow device 209 through the L-shaped connecting device 208, and the purpose is to change the flow direction of the molten glass, namely, the flow direction is changed from the horizontal direction to the vertical direction. The molten glass after passing through the overflow device 209 overflows and turns outwards from the outside of the overflow device 209 and then is melted at the root, the sheet width of the glass is ensured under the action of the edge-drawing device 210, and finally, the molten glass is downward under the action of the traction mechanism 211 by utilizing the self-weight of the glass to form a continuous glass ribbon 212.

The pulling mechanism 211 generally comprises a plurality of groups of pulling rolls, which are divided into a main pulling roll and a driven pulling roll. During the down draw process, the bosses of the primary pull rolls directly contact the surface of the glass ribbon 212 to gauge the thickness of the substrate glass and the driven pull rolls stabilize the motion of the glass ribbon 212.

The glass ribbon 212 naturally flows downward due to its own weight under the action of the drawing mechanism 211, and forms a "C" shape, ensuring the shape of the glass sheet, and forming a flat warp shape. However, the "C" shape may be partially deformed due to external factors. Such as: in the substrate glass production line 200, the thermal environment of the glass ribbon 212 is not consistent, the running state of the drawing mechanism 211 is changed, such as the wear is inconsistent, the center line and the glass ribbon 212 are deviated, or a plurality of groups of drawing rollers run asynchronously, and the like, and the changes may cause the distortion of the "C" shape of the glass ribbon 212, thereby affecting the quality of the substrate glass warpage. To enhance the "C" stabilization, the glass ribbon 212 can be in a stabilized configuration by manipulating the apparatus 100 in this embodiment.

After the second control element 70 is operated for a long time, the gas in the sealed space 712 may leak, or the external air flows in, so that the position of the sealing block 73 in the normal state and the initial position are changed, the accuracy of the position for controlling the guide wheel 40 to move is lowered, the sealing head 75 may be opened at this time, the atmosphere is communicated with the sealed space 712, the sealing block 73 is adjusted to the initial position, the communication head 711 is closed by the sealing head 75 at this time, so that the sealed space 712 is closed, and thus, the sealing block 73 can be located at the initial position preset by the user after being reset.

According to the control device 100 provided in this embodiment, the operation principle of the control device 100 is as follows:

through the adjustment of the first adjusting member 10, the second adjusting member 20 and the third adjusting member 30, the guide wheel 40 can be positioned at a proper position within a certain range, the guide wheel 40 guides the glass ribbon 212, the C-shaped form of the glass ribbon 212 can be maintained, the warping degree of the glass ribbon is favorably maintained, and the quality after production is improved.

Example 2

The embodiment provides a regulation method using the regulation device 100, and the method includes:

at least one of the first regulating member 10, the second regulating member 20 and the third regulating member 30 is controlled to bring the guide wheel 40 into contact with the position to be contacted of the glass ribbon 212 and to guide the flow of the glass ribbon 212.

The structure of the control device 100 can be referred to in example 1.

Referring to fig. 8, the substrate glass 300 shown in fig. 8 is naturally warped. Therefore, the guide wheels 40 on both sides of the glass ribbon 212 do not contact the glass ribbon 212, and only the edge-drawing device 210 and the pulling mechanism 211 contact the glass ribbon 212, so that the glass ribbon 212 is in the state of fig. 9.

Referring to fig. 10, the substrate glass 300 shown in fig. 10 is interfered by the outside. At this time, the guide wheels 40 on the left side of the ribbon 212 may be driven to the right to contact the ribbon 212, while the guide wheels 40 on the right side of the ribbon 212 are not in contact with the ribbon 212, in the state of fig. 11. Alternatively, the guide wheels 40 on the left side of the glass ribbon 212 are driven out of contact with the glass ribbon 212, and the guide wheels 40 on the right side of the glass ribbon 212 are moved leftward into contact with the glass ribbon 212, in the state shown in fig. 12.

Referring to fig. 13, the substrate glass 300 shown in fig. 13 is interfered by the outside. The guide wheels 40 on the left side of the ribbon 212 may now be driven upward and into contact with the ribbon 212, while the guide wheels 40 on the right side of the ribbon 212 are not in contact with the ribbon 212, in the condition of fig. 14. Alternatively, the guide wheels 40 on the left side of the ribbon 212 are driven to move downward and contact the ribbon 212, while the guide wheels 40 on the right side of the ribbon 212 are not in contact with the ribbon 212, in the state of FIG. 15.

Therefore, when the produced substrate glass 300 is interfered by the outside and the warp of the substrate glass 300 is deformed, the control devices 100 positioned at the left and right sides of the glass ribbon 212 can be controlled simultaneously or independently according to the specific deformation condition, so that the respective guide wheels 40 move up and down, back and forth and left and right and are in contact with or not in contact with the glass ribbon 212, thereby achieving the expected effect.

It is understood that the regulating device 100 can stabilize the flow of the glass ribbon 212 and compensate for the flow shape of the glass ribbon 212 under the deformed condition, so that the substrate glass 300 can be stably warped. On one hand, the warp quality fluctuation of the substrate glass 300 caused by the C-shaped distortion of the glass ribbon 212 due to the abnormality of the traction mechanism 211 or other conditions is compensated online, and on the other hand, the shaking of the glass ribbon 212 in the flowing process is reduced, and the flowing form of the glass ribbon 212 is stabilized.

In summary, the present invention provides a regulating device 100, which can regulate the position of the guide wheel 40 contacting the glass ribbon 212 through the first regulating member 10, the second regulating member 20 and the third regulating member 30, so that the guide wheel can contact the area to be contacted, and can stabilize the flowing state of the glass ribbon 212 and improve the quality of the produced substrate glass by abutting and guiding the glass ribbon 212 to flow.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
