[0026] See attached document Figures 1 to 3As shown in the illustration, this application provides an optical glass sheet forming transition roller table, including a frame 18, a conveyor roller assembly, and a heating and insulation assembly. The frame 18 is equipped with an adjustable-angle and adjustable-height conveyor roller assembly, and the heating and insulation assembly is arranged along the conveying direction of the conveyor roller assembly. By setting an adjustable-height and adjustable-angle conveyor roller assembly between the forming system and the annealing furnace, the roller table surface can adapt to the installation height and angle of the equipment on both sides. This allows the optical glass sheet flowing from the forming system into the annealing furnace smoothly. Simultaneously, the heating and insulation assembly on the roller table surface controls the temperature of the optical glass sheet as it passes through the roller table surface, preventing a sudden drop in temperature and ensuring the temperature stability of the optical glass sheet throughout the entire process from the forming system to the annealing furnace.

[0027] Specifically:

[0028] like Figures 1 to 3 As shown, the entire frame 18 is constructed by welding rectangular tubing and steel plates together to ensure the structural strength of the entire machine and prevent structural deformation in high-temperature continuous production environments. The frame 18 is equipped with height adjustment components and angle adjustment components for adjusting the height and angle of the conveyor roller assembly. These components are located at the front and rear ends of the conveyor roller assembly, respectively. One set adjusts the height of the front connecting equipment, and the other set adjusts the angle of the rear connecting equipment. See details below. Figure 3 The height adjustment component includes two first lifting mechanisms on the left and right. The first lifting mechanisms are connected by a first connecting shaft to achieve synchronous lifting. The first lifting mechanism is located between the frame 18 and the conveyor roller assembly. The first lifting mechanism is fixed to the surface of the frame 18 by bolts. The first lifting mechanism is movably hinged to the roller mounting frame 3 of the conveyor roller assembly. The angle adjustment component includes two second lifting mechanisms on the left and right. Similarly, the second lifting mechanisms are connected by a second connecting shaft to achieve synchronous lifting. The second lifting mechanism is located between the frame 18 and the conveyor roller assembly, and is movably hinged to the bottom bracket and the roller mounting frame 3 of the top conveyor roller assembly, respectively.

[0029] In one specific embodiment, the first and second lifting mechanisms are worm gear jacks 17. Worm gear jacks 17 in the same group are connected by a connecting shaft 4 via a coupling 5. A handwheel 6 is mounted on each worm gear jack 17, allowing adjustment of the worm gear jack 17 to complete the lifting operation. Figure 3 On the left, a set of worm gear jacks 17 has a hinge seat 16 mounted on top, which is connected to the roller mounting bracket 3 and fixed to the frame 18 below by bolts. On the right, a set of worm gear jacks 17 has hinge seats 16 mounted on both the top and bottom, thus enabling angle adjustment.

[0030] Meanwhile, the conveyor roller assembly includes a roller mounting frame 3, rollers 7, and a drive mechanism. The drive mechanism uses a servo motor 15 paired with a planetary gear reducer, which drives the six rollers 7 to rotate simultaneously through bevel gear transmission, thus pulling the formed glass strip forward into the annealing furnace.

[0031] Specifically, such as Figure 2 As shown, the roller drive shaft 12 is mounted on the roller mounting frame 3 with the second bearing 9 at both ends. The roller 7 is mounted on the roller mounting frame 3 with the first bearing 8 at both ends. The roller drive shaft 12 is arranged on the same end of the roller 7 in a direction perpendicular to the axis of the roller 7. A second bevel gear 11 is mounted on the end of the roller 7 near the roller drive shaft 12. Six first bevel gears 10 are mounted in the middle section of the roller drive shaft 12. A third bevel gear 13 is mounted on one end of the roller drive shaft 12. The six first bevel gears 10 in the middle mesh with the second bevel gears 11 on the six rollers 7. The third bevel gear 13 on the end meshes with a fourth bevel gear 14. The fourth bevel gear 14 is mounted on the output shaft of the reducer. A servo motor 15 drives the six rollers 7 to rotate, thereby pulling the formed glass strip forward into the annealing furnace.

[0032] In the above description, roller 7 is composed of quartz ceramic and metal materials. The middle section, which is in direct contact with the glass belt, is made of quartz ceramic, which can withstand high temperatures of around 1000℃ without deformation and with minimal expansion. The two ends, where it is assembled with the bearings, are made of metal materials, which have a certain strength and wear resistance. The quartz ceramic in the middle section and the metal materials at both ends are bonded together with a specific adhesive to form one roller 7. The entire device has six rollers 7. It should be noted that the number of rollers 7 is only an example and is not intended as a limitation.

[0033] In some cases, the heating and insulation component is an integrated module that is detachable from the frame 18 for easy maintenance, installation, and debugging. This component consists of an outer frame, an insulation layer, and a heating structure. The outer frame is welded from Q235 steel plates, providing excellent stability. The inner layer of the outer frame houses the heating and insulation structure. The insulation layer is made of high-temperature resistant fiberboard and is bolted to the outer frame. The heating structure uses a high-temperature nickel-chromium strip and a refractory furnace plate. The nickel-chromium strip can be heated to 1000℃ and is fixed to the refractory furnace plate, which is in turn fixed to the outer frame. A silicon carbide plate is also mounted on the furnace plate for uniform heating. The entire heating and insulation component is temperature-controlled by an upper heating and insulation unit 1 located above the conveyor roller assembly and a lower heating and insulation unit located below the conveyor roller assembly. A channel hole is provided between the upper and lower heating and insulation units to facilitate the passage of the glass strip.

[0034] In one embodiment, the upper and lower heating and insulation units are connected by bolts, allowing the upper heating and insulation unit to be quickly removed in case of emergencies (such as when glass becomes stuck and accumulates). The lower heating and insulation unit has two square holes on its side for removing glass shards that have fallen during molding; these holes are sealed with two standard heat-resistant bricks during normal operation. Both the upper and lower heating and insulation units are equipped with thermocouples for monitoring the temperature of the upper and lower heating zones and for automatic temperature adjustment.

[0035] In summary, the optical glass sheet forming transition roller table provided in this application has the following beneficial effects:

[0036] First: In this transition roller table, the heating and insulation structure is divided into upper and lower parts, which are easy to disassemble and facilitate the installation, debugging and maintenance of the rollers;

[0037] Secondly, in this transition roller table, the entire roller table surface can be adjusted in angle and height, has good compatibility, and can accurately match the height and angle positions of the equipment on the front and rear sides.

[0038] Third, in this transition roller stage, the heating and insulation components are equipped with silicon carbide plates for uniform heating, and the temperature is controlled at the top and bottom respectively, which improves the stability of the temperature field inside the furnace.

[0039] Fourth, in this transition roller table, the roller material is made of quartz ceramic, which has good high temperature resistance and is not easily deformed, has a small expansion amount, and is not easily reacted with glass belt under high temperature environment, thus improving the roller life and product quality.

[0040] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
