Description

Technical Field

[0001] This utility model relates to the field of glass manufacturing processes, and in particular to a float glass annealing roller hanging device. Background Technology

[0002] Annealing is the final step in the hot-end process and a crucial final step in glass production, affecting the maximization of overall production efficiency. In the float glass process, the annealing furnace is used to reduce or eliminate residual internal stress in the glass, ensuring proper annealing and cooling of the glass strip after it leaves the tin bath. To guarantee the annealing requirements of float glass, the annealing furnace is divided into four zones from front to back: Zone A (B), Zone C, Zone Ret (Rest), and Zone F. Each zone has a different temperature according to the annealing requirements of the glass, and the zones are separated by baffles. Additionally, observation holes are provided above the roller conveyors on both sides of the furnace, and a broken glass cleaning door is located at the bottom for cleaning broken glass. Annealing primarily controls glass stress and warpage, bringing them within the required range.

[0003] Annealing rollers are the carriers for transporting glass in annealing furnaces. Currently, ceramic annealing rollers are widely used in traditional ceramics and glass tempering industries, and their superior performance at high temperatures is undeniable. Ceramic annealing rollers are mainly classified by material: silicon carbide, high-alumina, and fused silica. Silicon carbide rollers are primarily used at extremely high temperatures and are very expensive. Fused silica and high-alumina rollers are most commonly used at medium and low temperatures, suitable for the low temperatures and wide widths of glass annealing furnaces. Currently, fused silica is the most suitable material, made by casting high-purity quartz slurry, firing in an oxidizing atmosphere, and then surface grinding. High-alumina materials use a combination of several mineral materials to ensure their high-temperature performance, but have relatively poor thermal shock stability; however, they are inexpensive and readily available. Fused silica ceramic annealing rollers, under the same design specifications, exhibit virtually no loss of mechanical properties in the high-temperature atmosphere of the annealing furnace. Their near-perfect chemical inertness and dense amorphous structure allow their surface to remain bright and new for a long time. However, the disadvantages of ceramic annealing rollers are also obvious, namely their high price. High-purity quartz, a material currently used, is difficult to obtain, and the costs of pulverization, melting, and machining are also high, making it almost impossible to obtain a lower purchase price. This inherently limits the price of ceramic annealing rollers, deterring most customers. Furthermore, the maintenance-free nature of ceramic annealing rollers also means that if a problem occurs, the entire roller may be essentially scrapped, requiring high management standards. Additionally, the composite support structure used at the ends of ceramic annealing rollers requires modifications to the structure and dimensions compared to traditional transmission systems, further restricting their application in cold repair lines. Therefore, the operating cost of ceramic annealing rollers is very high, requiring careful maintenance and management during their use.

[0004] The substrate glass accounts for a significant portion of the panel cost and greatly influences the performance of LCD products. Key technical indicators of the display are closely related to the substrate glass, such as transmittance, resolution, viewing angle, and weight. The substrate glass largely determines the panel's performance and quality. The glass substrate not only has high requirements for surface quality but also for its internal quality. The surface of the substrate for the thin-film transistor array should be free of scratches and blemishes, and surface defects should not exceed 100 micrometers, being completely invisible to the naked eye to avoid malfunctions such as open circuits or short circuits between lines in the circuitry. Internal bubbles and impurities must also be small enough and limited in number to not affect the quality of the displayed image. The quality of the formed substrate glass is also crucial; it should ideally be free of defects such as stones, streaks, bubbles, and stress, as these can lead to uneven display of the LCD panel and affect display quality. Foreign objects on the annealing rollers may scratch the glass or cause micro-defects on the glass surface. Therefore, some micro-defects that are not controlled in ordinary float glass are fatal to float electronic glass.

[0005] When foreign objects affecting glass quality appear on the annealing rollers, the conventional handling method is to remove the insulation material around the annealing rollers in the annealing furnace, disconnect the transmission device of the annealing rollers, use a special tool for handling annealing rollers to pull the abnormal annealing roller out of the annealing furnace, replace the abnormal annealing roller with a new one, and finally send the new annealing roller into the annealing furnace for installation. During production, when disassembling, maintaining, and installing annealing rollers, it is necessary to connect or detach the annealing rollers from the main longitudinal beam smoothly, safely, and quickly. To ensure the quality of TFT-LCD substrate glass, high requirements are placed on the roller spacing and parallelism when installing annealing rollers. Utility Model Content

[0035] The specific embodiments of this utility model are described in detail, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0036] like Figures 1 to 4 As shown in the figure, the float glass annealing roller hanging device provided in this embodiment includes a hanging assembly 100, a connecting assembly 200, and a clamping member 400, specifically:

[0037] The hanging assembly 100 mainly includes a first fixing member 110 and a second fixing member 120. The first fixing member 110 is provided with a first fixing part 111, which is configured as a fixing groove in this application. The fixing groove is linearly arranged on the first fixing member 110. The shape of the fixing groove in its cross-section is a "T" shape. In addition, the depth of the fixing groove on the first fixing member 110 is less than the thickness of the first fixing member 110.

[0038] Correspondingly, a second fixing part 121 is provided on the second fixing member 120 at the position corresponding to the fixing groove. The second fixing part 121 is configured as a fixing protrusion on the second fixing member 120. The fixing protrusion is linearly arranged on the second fixing member 120, and the shape of the fixing protrusion in its cross-section corresponds to the shape of the fixing groove in its cross-section. This is so that when the first fixing member 110 and the second fixing member 120 are assembled together, the second fixing part 121 is connected to the first fixing part 111. That is, the fixing protrusion is located in the fixing groove, and the outer periphery of the fixing protrusion is abutted and limited by the inner wall of the fixing groove, so that the first fixing member 110 and the second fixing member 120 are tightly connected.

[0039] In the above structure, the first fixing part 111 on the first fixing member 110 can also be configured as a fixing protrusion, and the second fixing part 121 on the second fixing member 120 can be configured as a fixing groove.

[0040] In this embodiment, both the first fixing part 111 and the second fixing part 121 are arranged linearly. To prevent the first fixing member 110 and the second fixing member 120 from moving horizontally along the direction of the first fixing part 111 and the second fixing part 121, a locking nut 600 is provided on the first fixing member 110 at a position perpendicular to the first fixing part 111 and the second fixing part 121. The locking nut 600 is movably disposed on the first fixing member 110. When the first fixing member 110 is connected to the second fixing member 120 through the first fixing part 111 and the second fixing part 121, the locking nut 600 can be manually or mechanically rotated so that one end of the locking nut 600 abuts against the fixing protrusion to prevent the first fixing part 111 and the second fixing part 121 from having relative displacement.

[0041] In this embodiment, a third fixing member 130 is also provided. The third fixing member 130 is located on one side of the second fixing member 120 relative to the first fixing member 110. In order to connect the second fixing member 120 and the third fixing member 130, a third fixing part 122 is provided on the second fixing member 120 on one side facing the third fixing member 130. That is, the third fixing part 122 is located on the second fixing member 120 relative to the second fixing part 121. The third fixing part 122 is vertically arranged on the second fixing member 120 relative to the second fixing part 121. In this embodiment, the third fixing part 122 is set as a fixing groove. The cross-section of the fixing groove is set as a "T" shaped structure, which is the same as the structure of the first fixing part 111 on the first fixing member 110. A fourth fixing part 131 is provided on the third fixing member 130 at the position corresponding to the third fixing part 122. That is, the fourth fixing part 131 is located on the side of the third fixing member 130 facing the second fixing member 120. The fourth fixing part 131 is set as a fixing protrusion on the third fixing member 130. The shape of the cross-section of the fixing protrusion corresponds to the shape of the cross-section of the fixing groove on the third fixing part 122. When the second fixing member 120 is connected to the fourth fixing part 131 on the third fixing member 130 through the third fixing part 122, the fourth fixing part 131 is located in the fixing groove of the third fixing part 122. The periphery of the fourth fixing part 131 is abutted and limited by the inner wall of the fixing groove of the third fixing part 122 to ensure a tight connection between the second fixing member 120 and the third fixing member 130.

[0042] Based on this structure, in this embodiment, the third fixing part 122 can be configured as a fixing protrusion, and the fourth fixing part 131 can be configured as a fixing groove. To further improve the connection stability between the second fixing member 120 and the third fixing member 130, a locking bolt 700 is provided on the second fixing member 120 at a position perpendicular to the third fixing part 122 and the fourth fixing part 131. The locking bolt 700 is movably disposed on the second fixing member 120. When the second fixing member 120 and the third fixing member 130 are assembled together, the locking bolt 700 can be manually or mechanically rotated so that one end of the locking bolt 700 abuts against the fourth fixing part 131 to prevent relative displacement between the third fixing part 122 and the fourth fixing part 131.

[0043] Based on the above structure, a limiting member 300 is provided on the third fixing member 130. The limiting member 300 is located on one side of the third fixing member 130 relative to the fourth fixing part 131. The limiting member 300 and the third fixing member 130 cooperate to form a fixing groove 310, which is used to connect the hanging assembly 100 and the connecting assembly 200. In this embodiment, the connecting assembly 200 mainly includes a fixing beam 210. An abutment member 220 is provided on the fixing beam 210 at a position corresponding to the fixing groove 310. The shape of the abutment member 220 matches the fixing groove 310, so that the connecting assembly 200 can be stably connected to the hanging assembly 100. Under the action of the fixing beam 210, the connecting assembly 200 can maintain a stable state, thereby ensuring the stability and reliability of the entire hanging device.

[0044] A clamping member 400 is positioned below the connecting assembly 200 and is used to clamp the annealing roller 500. The clamping member 400 includes a first clamping jaw 410 and a second clamping jaw 420, which are arranged opposite to each other to form a clamping portion 430. This clamping portion 430 serves as a clamping space for the annealing roller 500. The inner surfaces of both the first clamping jaw 410 and the second clamping jaw 420 are covered with a high-temperature resistant ceramic layer. This ceramic layer has excellent high-temperature resistance, effectively preventing damage to the clamping member 400 or scratches on the surface of the annealing roller 500 caused by high temperatures. Simultaneously, a graphite heat-insulating pad is provided between the ceramic layer and the first clamping jaw 410 and the second clamping jaw 420, further improving the high-temperature resistance and heat insulation effect of the clamping member 400.

[0045] In this embodiment, the clamping member 400 and the connecting assembly 200 are connected by a fixing nut to the clamping member 400 so that the connecting assembly 200 connects and fixes the clamping member 400.

[0046] An adjusting nut 440 is provided between the first gripper 410 and the second gripper 420. The clamping angle between the first gripper 410 and the second gripper 420 can be adjusted by adjusting the nut 440, thus accommodating annealing rollers 500 of different specifications and sizes. Fixed shafts 510 are provided at both ends of the annealing roller 500. Two first abutment surfaces 511 are horizontally provided on the fixed shafts 510, symmetrically arranged on both sides of the fixed shafts 510. Second abutment surfaces 450 are horizontally provided on both the first gripper 410 and the second gripper 420. When the first gripper 410 and the second gripper 420 clamp the fixed shaft 510, the first abutment surfaces 511 abut against the second abutment surfaces 450, thereby achieving stable clamping of the annealing roller 500.

[0047] This utility model provides a suspension device for annealing rollers of float electronic glass. When it is necessary to install or remove the annealing roller 500, the main body of the suspension device is placed on the suspension beam of the annealing roller 500. The annealing roller 500 is connected to the suspension device by a hoist, and then the hoist is pulled to lift the annealing roller 500 for installation or removal. The position of the annealing roller 500 can be finely adjusted by rotating the locking nut 600. Through the coordinated arrangement of the suspension component 100, connecting component 200, and clamping component 400, the annealing roller 500 can be quickly, stably, and safely suspended and removed. This suspension device has a simple structure, is easy to operate, and has a wide range of applications, effectively improving the production efficiency and product quality of float electronic glass. At the same time, this suspension device also has excellent high-temperature resistance and heat insulation effect, meeting the requirements of use in high-temperature environments, and providing strong technical support for the production of float electronic glass.
