Detailed Description
The following describes specific embodiments of the present invention in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the invention, are not intended to limit the invention.
In the present invention, unless otherwise indicated, terms of orientation such as "inner and outer" are used to refer to inner and outer relative to the outline of the components themselves.
The invention provides a glass liquid feeding device which comprises a feeding pipe 1 and a regulator 2, wherein the feeding pipe 1 comprises a discharging end 11, the size of a pipe orifice of the discharging end 11 is set to be variable, and the regulator 2 is arranged at the discharging end 11 and used for regulating the size of the pipe orifice of the discharging end 11.
The glass liquid feeding device realizes the adjustment of the glass liquid discharge amount by setting the pipe orifice of the discharge end 11 of the feeding pipe 1 to be variable and adjusting the pipe orifice of the discharge end 11 by using the adjustor 2; the invention achieves the purpose of changing the discharging amount of the glass liquid by the mechanical equipment adjusting means, and can avoid the problems of glass plate thickness change, local extremely poor fluctuation of the glass plate, exceeding of the stress of the glass plate and the like caused by changing the temperature of the glass liquid.
In the above description, since the temperature of the molten glass conveyed in the feed tube 1 is as high as 1000 degrees, the feed tube 1 is generally made of a high temperature resistant material, such as a platinum tube. The present invention sets the nozzle size of the discharge end 11 of the feed tube 1 to be variable, and it is understood that the nozzle size is variable at high temperature. For example, according to one embodiment of the invention, folds 12 are provided in the wall of the discharge end 11 in the radial direction of the feed pipe 1. In this way, at high temperature, the hardness of the pipe wall of the feed pipe 1 is reduced, the existence of the folds 12 provides a certain deformation amount for the pipe wall, and when the pipe wall is subjected to external force, such as inward constraint force, the pipe orifice of the discharge end 11 can be reduced, so that the discharge amount of molten glass is reduced; when the outward expansion force is applied, the folds 12 gradually tend to be smoothed so that the pipe orifice of the discharging end 11 becomes larger, and the discharging amount of the molten glass is increased. In addition, because fold 12 only sets up in the discharge end 11 of feed tube 1, in the in-process that discharge end 11 mouth of pipe changed, can not exert an influence to the pipe wall of the feed end of feed tube 1 to the reliability of feed tube 1 has been guaranteed.
Preferably, as shown in fig. 1, a plurality of pleats 12 are disposed on the pipe wall of the discharge end 11, and the pleats 12 are arranged at intervals along the circumferential direction of the feed pipe 1. Thus, the adjusting quantity of the pipe orifice of the discharging end 11 can be increased, and the adjusting range of the discharging quantity of the glass liquid is enlarged. In addition, the adjustment of the orifice of the discharge end 11 can be made more uniform, i.e. the orifice can vary over the circumference.

That is, the connection position of the connecting piece 22 and the other end of the adjusting belt 21 can be adjusted to adjust the looping size of the adjusting belt 21, so that the force applied by the adjusting belt 21 to the pipe wall of the discharging end 11 is changed.
Since the feed pipe 1 is in a high temperature state when the molten glass is fed, the regulator 2 should be made of a high temperature resistant material such as steel, platinum, or the like. In addition, other tools may be used to apply inside-out forces to the tube wall as the orifice is enlarged.
The present invention is not limited to the connection of the above-described connection member 22 to the other end of the adjustment belt 21, and it may be implemented in any manner as long as the loop forming size of the adjustment belt 21 can be changed. For example, the connecting member 22 may be a pin penetrating one end of the adjusting belt 21 in the radial direction of the adjusting belt 21, the other end of the adjusting belt 21 may be provided with a plurality of insertion holes arranged at intervals in the length direction of the adjusting belt 21, and the looping size of the adjusting belt 21 may be adjusted by selectively inserting the pin into one of the plurality of insertion holes.

The "penetrating direction" may refer to a left-to-right direction shown in fig. 2, and the "front" refers to the right side in fig. 2, and the "rear" refers to the left side in fig. 2.
The above-mentioned "the other end of the adjustment belt 21 can be extended and retracted back and forth in the penetrating direction thereof in the through hole 221 in a lockable manner" can be realized by any means, such as a snap structure, and the present invention is not limited thereto.

Of course, the grooves 211 may be replaced by holes.
Further, in order to ensure that the other end of the adjustment belt 21 is smoothly retreated in the through hole 221, a bottom wall of the connecting member 22 for defining the through hole 221 may be provided to be inclined upward in the direction in which the adjustment belt 21 is threaded (see fig. 3). Wherein the orientation "bottom" is defined with reference to the orientation shown in fig. 3.
In the present invention, in order to secure the stability and reliability of the use of the regulator 2, the regulator 2 may be fixed to the feed pipe 1.
