It is a core component in the upstream of liquid crystal panels. The manufacturing of carrier glass requires high precision. In the forming stage, it can mainly be formed by the float method, the flow hole down-drawing method, and the overflow melting method, etc. The overflow melting technology can produce ultra-thin glass substrates with two original glass surfaces.

In addition, the present utility model may repeat reference numerals and / or reference letters in different examples. Such repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between various embodiments and / or settings discussed.

[0053] Referring to Figure 1 , the present application proposes a flow rate adjustment structure and a carrier glass overflow forming device. The flow rate adjustment structure is used to adjust the input flow rate of molten glass in the carrier glass overflow forming device.

[0054] The flow rate adjustment structure includes a feeding assembly, a docking part 230, and an adjustment assembly.

[0055] The feeding assembly includes a feeding pipe group 300, and a feeding channel is formed in the feeding pipe group 300.

[0056] The docking part 230 is formed at the feeding end of the overflow forming device. A through docking port is formed on the docking part 230, and the discharging end of the feeding pipe group 300 is connected to the docking port.

[0057] The carrier glass overflow forming device specifically includes an overflow brick body 100, a baffle assembly 200, a support cross beam 400, and a support assembly 500.

[0058] The overflow brick body 100 includes an upper overflow body 110 and a lower overflow body 120. The lower overflow body 120 is located below the upper overflow body 110, and the upper overflow body 110 and the lower overflow body 120 are an integrally formed structure.

[0059] An overflow groove 111 is formed in the upper overflow body 110. The two sides of the overflow groove 111 are overflow weirs. The overflow groove 111 is a structure with an upper opening and is used to hold the molten glass for forming the carrier glass.

[0060] Flow guiding walls 121 are formed on both sides of the lower overflow body 120. After the molten glass reaches the accommodation upper limit in the overflow groove 111, it overflows downward from the overflow weirs on both sides of the overflow groove 111, forms a sheet-like substrate along the surface of the flow guiding walls 121, and is finally pulled by the traction rollers in the forming area to form the carrier glass.

[0061] The baffle assembly 200 includes a first baffle member 210 and a second baffle member 220 respectively formed at both ends of the overflow groove 111. The upper edges of the first baffle member 210 and the second baffle member 220 are higher than the overflow groove 111 to prevent the molten glass from overflowing from both ends of the overflow groove 111.

[0062] The docking part 230 is specifically arranged on the first baffle member 210. The docking part 230 is used to connect with the feeding component. The feeding component includes a feeding pipe group 300, and the feeding pipe group 300 transports the molten glass into the overflow tank 111 through the feeding pipe group 300.

[0063] The docking part 230 is detachably connected to the first baffle member 210 to adapt to the overflow brick body 100 of different lengths, so as to produce carrier glass of different width sizes, and the versatility is stronger.

[0064] Reference Figures 2 - 6 , a flow regulating component 600 is arranged on the docking part 230 for regulating the flow rate of the molten glass input into the overflow tank 111.

[0065] Specifically, a through docking port 231 is formed on the docking part 230. The regulating component 600 is installed in the docking port 231. One side of the docking port 231 is communicated with the output end of the feeding pipe group 300, and the other end is communicated with the overflow tank 111.

[0066] Next, the regulating component 600 will be described in detail:

[0067] The regulating component 600 includes a fixed ring plate 610, a rotating ring plate 620, a set 630 of rotating blades 631 and a driving member 640.

[0068] The fixed ring plate 610 is of a ring structure, and its circumferential side is fixed in the docking port 231. A plurality of rotating bases 611 are uniformly arranged along the circumferential direction on one side of the fixed ring plate 610.

[0069] The rotating ring plate 620 is also of a ring structure, and its outer wall is rotatably connected in the docking port 231. A plurality of movable guide grooves 621 are uniformly arranged along the circumferential direction on the rotating ring plate 620.

[0070] The fixed ring plate 610 and the rotating ring plate 620 are arranged at intervals along the axis direction of the docking port 231, and the fixed ring plate 610 and the rotating ring plate 620 are parallel to each other.

[0071] The set 630 of rotating blades 631 is arranged between the fixed ring plate 610 and the rotating ring plate 620, and includes a plurality of rotating blades 631 arranged to rotate around the axis of the docking port 231 at a preset angular pitch.

[0072] Specific reference Figure 6 , each rotating blade 631 is similar to a crescent shape, and a notch with an opening facing the center direction of the docking port 231 is formed thereon.

[0073] Feeding ports are formed between the rotating blades 631, and the size of the feeding ports changes as the rotating blades 631 rotate.

[0074] Both sides of the rotating blade 631 are respectively connected to the fixed ring plate 610 and the rotating ring plate 620. Specifically, a first connecting portion 632 is formed at the first end of each rotating blade 631, and a second connecting portion 633 is formed at the second end. The first connecting portion 632 and the second connecting portion 633 are respectively located on both sides of the rotating blade 631. The first connecting portion 632 is located on the side close to the fixed ring plate 610, and the second connecting portion 633 is located on the side close to the rotating ring plate 620.

[0075] The first connecting portion 632 is correspondingly connected to the rotating base portion 611, and the second connecting portion 633 is connected to the movable guide groove correspondingly.

[0076] The driving member 640 is connected to the outside of the docking portion 230, and its output shaft passes through the docking portion 230 and is connected to the rotating ring plate 620 for driving the rotating ring plate 620 to rotate around the axis of the docking port 231.

[0077] Reference Figure 3 、 Figure 5 Specifically, the driving member 640 includes a driving motor 641 and a transmission gear 642 connected to the output end of the driving motor 641.

[0078] A toothed section 622 is formed on the outer wall of the rotating ring plate 620, and transmission teeth cooperating with the transmission gear 642 are provided on the toothed section 622. The transmission gear 642 is cooperatively connected with the toothed section 622 for driving the rotation of the rotating ring plate 620 to drive each rotating blade 631 to rotate at an angle around the corresponding rotating base portion 611, thereby adjusting the size of the feed port.

[0079] Each movable guide groove 621 extends along the radial direction of the rotating ring plate 620. When the rotating ring plate 620 rotates, the movable guide groove drives the second connecting portion 633 to rotate, and the second connecting portion 633 displaces relative to the movable guide groove. Each rotating blade 631 rotates around the first connecting portion 632, so that the positions between the rotating blades 631 are changed, thereby changing the size of the feed port formed between the rotating blades 631.

[0080] A housing body extending towards the rotating ring plate 620 is formed on the fixed ring plate 610, and the rotating ring plate 620 is rotatably connected within the housing body.

[0081] An annular rotating groove is formed on the inner side of the housing body. The rotating ring plate 620 is connected within the rotating groove, and auxiliary rotating structures such as bearings can be provided between the rotating ring plate 620 and the rotating groove to improve the smoothness of rotation.

[0082] In some embodiments of the present application, the rotating base 611 is a rotating groove formed on one side of the fixed ring plate 610, the first connecting portion 632 is a rotating column extending along the direction away from the rotating blade 631, and the first connecting portion 632 is rotatably connected within the rotating base 611.

[0083] Alternatively, it can also be designed such that the rotating base 611 is a rotating column formed on the fixed ring plate 610 and extending towards the rotating blade 631, and the first connecting portion 632 is a rotating groove, and the rotating base 611 is rotatably connected within the first connecting portion 632.

[0084] The second connecting portion 633 is a connecting column extending along the direction away from the first connecting portion 632, and the second connecting portion 633 is inserted into the movable guide groove and can move along the corresponding movable guide groove.

[0085] The adjusting assembly 600 can adjust the opening size of the feed port to adapt to overflow grooves 111 of different sizes, and the adjustment method is to equally inwardly contract or equally outwardly expand towards the center of the feed port, so that the molten glass input from the feed port into the overflow groove 111 is more uniform, avoiding problems such as uneven thickness of the carrier glass caused by uneven input of molten glass in the overflow groove 111 and poor quality of the finished product.

[0086] Reference Figures 7 - 10 , since the overflow brick body 100 is prone to high-temperature creep under high-temperature conditions, therefore, the middle position of the overflow groove 111 sags, resulting in uneven thickness during the production of the carrier glass and affecting the display imaging effect.

[0087] To solve the above problems, a support channel 122 extending along the length direction of the lower overflow body 120 is formed within the lower overflow body 120 in the present application.

[0088] A support cross beam 400 is connected within the support channel 122. The support cross beam 400 penetrates within the support channel 122 to support the overflow brick body 100, reducing the sagging phenomenon of the overflow groove 111, and the support cross beam 400 can also support the entire overflow brick body 100 to facilitate its fixation.

[0089] The depth of the overflow groove 111 gradually decreases along the direction from the first baffle member 210 to the second baffle member 220.

[0090] Refer again to Figure 1 , a diversion portion 130 is formed on the side of the second baffle member 220 close to the overflow groove 111. The diversion portion 130 is located within the overflow groove 111, and the diversion portion 130 tapers along the direction away from the second baffle member 220.

[0091] The flow - dividing part 130 is used to divide the molten glass in the direction of the overflow weir, reducing the impact of the molten glass on the second baffle member 220.

[0092] In some embodiments of the present application, a support assembly 500 is respectively provided at both ends of the overflow brick body 100. Each support assembly 500 includes a support base 510 and a support platform 520 provided on the support base 510. A support groove 521 is formed on the support platform 520, and both ends of the support cross - beam 400 are respectively supported in the corresponding support grooves 521.

[0093] The support base 510 is installed at a preset working height through a support structure such as a bracket, and the overflow brick body 100 is fixedly supported on the support assembly 500 through the support cross - beam 400.

[0094] In some embodiments of the present application, in order to improve the connection stability between the support channel 122 and the support cross - beam 400 and enhance the support effect of the support cross - beam 400 on the overflow groove 111, in some embodiments of the present application, the cross - sectional dimension of the support channel 122 gradually decreases from top to bottom. The top surface of the support channel 122 is a plane, and the shape of the support cross - beam 400 is adapted to the support channel 122.

[0095] That is, the cross - sections of the support channel 122 and the support cross - beam 400 are formed as triangles. Preferably, they are isosceles triangles with the bottom surface of the triangle facing up and the tip facing down.

[0096] In other embodiments, the top surface of the support channel 122 can also be designed as a convex arc surface. The shape of the support cross - beam 400 is adapted to the support channel 122. The convex arc surface can further increase the contact area of the support cross - beam 400 and avoid problems such as stress concentration.

[0097] The cross - sectional width dimension of the support groove 521 gradually decreases along its depth direction, and at least part of the support cross - beam 400 is connected in the support groove 521.

[0098] The support platform 520 is used to support the support cross - beam 400. In addition, a limit support member 530 is provided on the support base 510 to limit the horizontal direction of the support cross - beam 400.

[0099] Combined with Figures 8 - 10 , the length direction of the limit support member 530 is perpendicular to the length direction of the support cross - beam 400. A limit groove 531 is formed along the length direction of the limit support member 530. A limit notch 410 with a downward opening is formed on the support cross - beam 400. The position of the limit notch 410 is adapted to the limit groove 531, and the limit notch 410 is connected in the limit groove 531 through a limit block 540.

[0100] The limit support member 530 is located on one side of the support base 510 close to the overflow brick body 100. During installation, after the two ends of the support cross beam 400 are respectively connected in the support groove 521, the limit block 540 is pushed from the limit groove 531 into the limit notch 410 to limit the horizontal direction of the support cross beam 400.

[0101] Furthermore, in order to limit the horizontal position between the support cross beam 400 and the overflow brick body 100, the distance between the two support bases 510 at both ends can be designed to be adapted to the maximum size of the baffle components 200 at both ends of the overflow brick body 100 to limit the horizontal position of the overflow brick body 100.

[0102] Alternatively, a horizontal limit structure can also be designed on the support base 510 to limit both ends of the overflow brick body 100 through horizontally adjustable screw rods and other structures, thereby supporting and limiting the overflow brick body 100 in all directions.

[0103] The screw rod can be movably connected to the support base 510 by means of threaded connection. After the installation of the overflow brick body 100 is completed, the screw rods at both ends are respectively moved to abut against the first baffle member 210 and the second baffle member 220 at the ends for limiting.

[0104] In some other embodiments of the present application, an avoidance portion 532 is further provided on the limit support member 530, and the support cross beam 400 passes through the avoidance portion 532 and is supported on the support table 520 to prevent the support cross beam 400 from interfering with the limit support member 530.

[0105] In the description of the above embodiments, the specific features, structures, materials or characteristics can be combined in a suitable manner in any one or more embodiments or examples.

[0106] The above are only the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
