[0034] Figures 1 to 6 An embodiment of the bottom bracket of the platinum channel of the present application is schematically shown. Figures 1 to 6 As shown, the present application discloses a bottom bracket of a platinum channel, which is used to support a feeding section 50 of the platinum channel, wherein the bottom bracket includes:

[0035] The bracket body 10 is tilted along the length direction to support the feeding section 50 of the platinum channel, so as to facilitate the glass liquid in the platinum channel to flow downward into the metal tin bath to be cooled to form a glass plate.

[0036] The support baffle 20 is arranged at one end of the bracket body 10 that is tilted downward, and supports and stops the feeding section 50 of the platinum channel, thereby offsetting the gravity component generated by the tilted placement of the platinum channel and ensuring that the platinum channel is fixed firmly.

[0037] The pushing mechanism 30 is provided with multiple groups, and the multiple groups of pushing mechanisms 30 are symmetrically arranged on both sides of the bracket body 10 along the length direction. The pushing mechanism 30 includes an adjusting bolt 33 for pushing the feeding section 50 of the platinum channel, and the adjusting bolt 33 can be rotated to change the length of the feeding section 50 of the platinum channel. The pushing mechanism 30 is symmetrically arranged on both sides of the bracket body 10. On the one hand, it can further fix the platinum channel from the side to improve the fixing stability. On the other hand, it can also suppress the free expansion of the platinum channel caused by high temperature during operation, improve the working state of the platinum channel, and avoid expansion displacement or extrusion damage to the internal and external structures of the platinum channel. In addition, the pushing mechanism 30 has an adjusting bolt 33, and the pushing length can be changed by rotating the adjusting bolt 33, so that the positioning, installation and adjustment of the platinum channel are more flexible.

[0038] Therefore, the bottom bracket of the platinum channel of the embodiment of the present application can stably support the platinum channel by using the tilted bracket body 10 and the support baffle 20 and the push mechanism 30 arranged on the bracket body 10, so that the glass liquid in the feeding section 50 of the platinum channel can smoothly flow into the tin bath to realize the glass plate manufacturing. In addition, the bottom bracket of the embodiment of the present application makes it easier to position and adjust the platinum channel, and at the same time has the effect of suppressing the free expansion of the platinum channel due to heat, which can improve the working state of the platinum channel, thereby maintaining the working operation of the platinum channel more conveniently and safely.

[0039] In some embodiments of the present application, Figure 5 As shown in the enlarged view, the pushing mechanism 30 also includes a fixed side plate 34 and a pad 35. The fixed side plate 34 mainly serves to fix the adjusting bolt 33. The fixed side plate 34 is fixedly connected to the bracket body 10 and is provided with a threaded hole. The pad 35 is installed on the outside of the feeding section 50 of the platinum channel, such as the fire brick on the outside of the platinum channel, and is aligned with the adjusting bolt 33. It mainly serves to expand the force-bearing area and protect the platinum channel structure (such as fire bricks). After the adjusting bolt 33 passes through the threaded hole, it continues to push the pad 35 to push the feeding section 50 of the platinum channel. With the pushing mechanism 30, the pushing length can be conveniently adjusted by rotating the adjusting bolt 33 during installation and use, thereby realizing flexible positioning of the platinum channel.

[0040] In some embodiments of the present application, continue as Figure 5As shown in the enlarged view, a disc spring 31 and a guide sleeve 32 are arranged between the fixed side plate 34 and the adjusting bolt 33, and the adjusting bolt 33 presses the pre-tightened disc spring 31 in the direction of the fixed side plate 34 through the guide sleeve 32. The disc spring 31, also known as the Belleville spring washer, is in the shape of a conical disc, has the advantages of short shape, small deformation, and large bearing capacity, and has high space utilization and saves installation volume. In the embodiment of the present application, a disc spring 31 is arranged at the adjusting bolt 33 and a preload is applied, so that the preload force can be used to improve the ability of the adjusting bolt 33 to resist the expansion of the platinum channel. The disc spring 31 can increase the vertical force on the load surface, thereby increasing the friction force, preventing the adjusting bolt 33 from loosening, playing a role in compensating for the influence of pressure fluctuations and temperature changes, and making the pushing effect of the adjusting bolt 33 more stable and reliable. The guide sleeve 32 transmits pressure between the adjusting bolt 33 and the disc spring 31, and at the same time has the function of constraining the disc spring 31 to stabilize its positioning.

[0041] In some embodiments of the present application, at least three disc springs 31 are provided, and at least three disc springs 31 can form a stacked disc spring group to obtain a better preload effect. The end surface of the disc spring group with a larger area (i.e., the concave end surface) faces the fixed side plate 34 to cope with the expansion load from the platinum channel side.

[0042] In some embodiments of the present application, the adjusting bolt 33 and the guide sleeve 32 are made of stainless steel, which is durable and not easy to rust, and has low cost. Since the platinum channel has a heat preservation layer, fireproof bricks and other structures on the outside, although the inside is at a high temperature to transport molten glass, the temperature on the outside will not rise too high, so the use of stainless steel can meet the use requirements and is conducive to controlling costs.

[0043] In some embodiments of the present application, the fixed side plate 34 is made of metal, and the fixed side plate 34 is welded to the bracket body 10. The fixed side plate 34 is welded, which is relatively more firm and reliable. Of course, it can be understood that other fixing methods can also be used in the present application. For example, when the fixed side plate 34 is made of non-metallic material, it can be fixed by bolts or the like, which will not be described in detail here.

[0044] In some embodiments of the present application, the support baffle 20 disposed at the downward end of the bracket body 10 is an angle steel. Angle steel is a long steel strip with two sides perpendicular to each other and angled. It has good supporting capacity, low cost, and flexible installation and construction. In this embodiment, the angle steel is welded to the downwardly inclined end of the bracket body 10 to support the platinum channel and offset the gravity component generated by the downwardly inclined setting of the platinum channel. Figure 6As shown, it is a schematic diagram of the side structure of the bottom bracket carrying the platinum channel in the embodiment of the present application. In the figure, the support baffle 20 is pressed against the bottom end surface of the feeding section 50 of the platinum channel to offset the gravity component caused by the tilt.

[0045] In some embodiments of the present application, the bottom bracket further includes a plurality of legs 40 of different heights, and the plurality of legs 40 of different heights are connected to the lower side of the bracket body 10 to support the bracket body 10. Figure 2 and Figure 6 As shown, the supporting leg 40 is arranged to rise from left to right, wherein the supporting leg 40 is connected to the bracket body 10 by a fixing bolt 41 .

[0046] In some embodiments of the present application, reference Figure 1 and Figure 4 As shown, the legs 40 are made of channel steel. Channel steel is a long steel strip with a groove-shaped cross section, which has good welding, riveting and comprehensive mechanical properties and can stably support the bracket body 10 and the platinum channel placed thereon.

[0047] In some embodiments of the present application, Figure 3 and Figure 4 As shown, each leg 40 includes two feet and a crossbeam, the two feet are respectively supported on both sides of the bracket body 10, and the crossbeam is connected between the two feet to support the bracket body 10, thereby achieving stable support. In the embodiment of the present application, the two feet are symmetrically arranged, and the bracket body 10 is placed in the middle of the crossbeam to ensure force balance.

[0048] The embodiments of the present application can be applied to TFT or OLED glass production lines, and have the advantages of smooth glass liquid circulation, stable and fixed platinum channel, flexible positioning, suppressed expansion, and longer service life.

[0049] In summary, the bottom bracket of the embodiment of the present application includes a bracket body 10, and a support baffle 20 and a push mechanism 30 arranged on the bracket body 10. The bracket body 10 is tilted, which can facilitate the glass liquid in the platinum channel to flow downward to the tin bath to realize the glass plate manufacturing. The support baffle 20 is arranged at the end of the bracket body 10 that is tilted downward, which can offset the gravity component force generated by the tilted setting of the platinum channel. The push mechanism 30 is symmetrically arranged on both sides of the bracket body 10. On the one hand, it can further fix the platinum channel from the side to improve the fixing stability. On the other hand, it can also suppress the free expansion of the platinum channel caused by high temperature during operation, improve the working state of the platinum channel, avoid expansion displacement or extrusion damage of the internal and external structures of the platinum channel, and extend the service life of the equipment. Moreover, the push mechanism 30 of the embodiment of the present application also has an adjusting bolt 33, which can be flexibly rotated to change the push length, and the positioning and adjustment of the platinum channel is more convenient. Therefore, the embodiment of the present application has high fixing stability for the platinum channel and easy positioning and adjustment, and at the same time has the effect of suppressing the free expansion of the platinum channel due to heat, which can improve the working state of the platinum channel, more conveniently and safely maintain the working operation of the platinum channel, extend the service life of the equipment, and reduce production costs.
