[0038] like Figure 1 As shown, the utility model provides a turntable device for a hot bending device, wherein the turntable device for the hot bending device comprises:

[0039] Turntable body 1;

[0040] An annular closed structure 2 is circumferentially arranged at the upper and lower parts of the turntable body 1;

[0041] The brackets 3 are provided in multiple groups, and the multiple groups of brackets 3 are arranged in sequence along the outer circumference of the turntable body 1. The end of each group of brackets 3 away from the turntable body 1 is configured with a hollow installation position 31 and a support plate 32 arranged in the installation position 31.

[0042] The turntable device for hot bending equipment provided by the embodiment of the utility model can provide an annular conveying line through the turntable body 1 and multiple groups of brackets 3. Each group of brackets 3 is configured with a hollow installation position 31 and a support plate 32 arranged in the installation position 31 at the end away from the turntable body 1. The glass to be processed is placed in the support plate 32 and passes through each processing station in sequence with the turntable device to complete the glass hot bending process. The multiple groups of brackets 3 are arranged in sequence along the outer circumference of the turntable body 1, and are adapted to the station body 8 with multiple independent working chambers, so that each group of brackets 3 is individually extended into an independent working chamber. After completing a processing step, it is driven by the turntable body 1 to enter the next working chamber. The working chambers do not affect each other. On the basis of stable rotation and conveying of glass, the glass can be efficiently processed in cooperation with each station. At the same time, the annular closed structure 2 arranged at the upper and lower parts of the turntable body 1 can seal the station body 8 and the turntable body 1 to prevent the gas in the station body 8 from leaking out.

[0043] Specifically, the station body 8 refers to a device used for processing glass in the hot bending equipment, see Figure 3 The station body 8 is arranged in a ring shape, and the turntable body 1 is arranged on the inner side of the station body 8. A plurality of independent workstations are arranged on the station body 8, such as a preheating station, a cooling station, a hot bending station and a loading station, so as to perform different processing steps correspondingly. Each workstation has one or more independent working chambers. A clearance opening is preset on one side of the working chamber close to the center of curvature. A plurality of clearance openings cooperate to form a rotating channel. The bracket 3 extends into the working chamber from the clearance opening. An openable and closable insulating door is arranged between adjacent working chambers. During processing, the insulating door falls to separate adjacent working chambers. Multiple groups of brackets 3 are arranged at intervals on the turntable body 1 and can be placed in each independent working chamber one by one. After the current glass processing step is completed, the insulating door is lifted to connect the various working chambers, and the turntable body 1 rotates to drive the glass into the next working chamber. The above steps are repeated to complete the turntable hot bending processing of the glass.

[0044] like Figure 1 and Figure 2 As shown, in an embodiment of the utility model, the turntable device for the hot bending equipment also includes an upper insulation board 4 and a lower insulation board 5, and the upper insulation board 4 and the lower insulation board 5 are respectively arranged at the upper part and the lower part of the turntable body 1 to form an annular closed structure 2, and the outer diameters of the upper insulation board 4 and the lower insulation board 5 are larger than the outer diameter of the turntable body 1, and the bracket 3 extends from the gap between the upper insulation board 4 and the lower insulation board 5.

[0045] Specifically, see Figure 2In a specific embodiment of the utility model, the annular closed structure 2 is configured as a sealing groove, and an upper sealing ring and a lower sealing ring are provided on the inner wall of the station body 8. The ends of the upper sealing ring and the lower sealing ring away from the inner wall of the station body 8 are embedded in the sealing grooves of the upper insulation board 4 and the lower insulation board 5 one by one, and the outer walls of the upper insulation board 4 and the lower insulation board 5 are spliced ​​with the inner wall of the station body 8 to play a role in heat insulation and sealing.

[0046] Specifically, in another specific embodiment of the utility model, the annular closed structure 2 is configured as a sealing part, and the sealing part protrudes from the upper insulation board 4 and the lower insulation board 5. A corresponding annular groove is formed on the station body 8 for the sealing part to be embedded, thereby realizing the sealing between the turntable body 1 and the station body 8.

[0047] Furthermore, cooling water channels are provided inside the upper insulation board 4 and the lower insulation board 5, and cooling of the insulation boards is achieved by inputting cooling water.

[0048] In the embodiment of the utility model, a spacer ring sealing plate 6 is provided between any two adjacent groups of brackets 3, and the upper and lower parts of the spacer ring sealing plate 6 are respectively sealed and spliced ​​with the upper insulation plate 4 and the lower insulation plate 5 to fill the gap between the adjacent brackets 3, and further improve the sealing effect between the turntable body 1 and the station body 8. Specifically, the spacer ring sealing plate 6 includes two sealing plate parts spliced ​​up and down, and the two sealing plate parts are correspondingly clamped on the upper and lower sides of the bracket 3, and the sealing plate parts on the two adjacent groups of brackets 3 are spliced.

[0049] In the embodiment of the utility model, a plurality of installation notches 11 are formed at intervals on the circumferential edge of the turntable body 1, and the installation notches 11 are tapered from the outside to the inside. A connection portion 33 of a trapezoidal structure is formed at one end of the bracket 3 facing the rotation center of the turntable body 1 to be embedded in the installation notch 11. This tapered design facilitates the rapid positioning and installation of the bracket 3.

[0050] Specifically, see Figure 4 The turntable body 1 includes a rectangular mounting portion 34 and a trapezoidal connecting portion 33, and one end of the mounting portion 34 away from the connecting portion 33 forms a mounting position 31. In addition, since the mounting portion 34 is in a suspended state, a hollow weight-reducing position 35 is provided between the mounting position 31 and the connecting portion 33 to reduce the weight of the mounting portion 34 and prevent the bracket 3 from bending.

[0051] In the embodiment of the utility model, the body of the bracket 3 is set to a heat-insulating material to maintain the temperature in the working chamber, avoid heat loss on the glass, and ensure the quality of glass processing. An infrared radiation array composed of multiple infrared radiation tubes is set in the preheating station to heat the glass by thermal radiation. The support plate 32 is hollow so that the rays emitted by the infrared radiation tube can directly irradiate the glass to improve thermal efficiency. The support plate 32 supports the glass, and the edge of the glass cannot directly contact the rays. Therefore, the support plate 32 is set to a heat-conducting material so that the heat on the support plate 32 can be quickly transferred to the glass to ensure uniform heating of the glass. Specifically, the bracket 3 is preferably a nano-microporous heat-insulating material, and the bracket is preferably a nickel-based alloy material with good thermal stability. It should be noted that the bracket 3 is spliced ​​by a plurality of connecting rods, and the materials of the connecting rods may not be exactly the same, but the connecting rods in contact with the support plate 32 must be set to high-quality heat-insulating materials.

[0052] Furthermore, a step for supporting the support plate 32 is formed on the mounting position 31, bolts are passed through the support plate 32, and corresponding connecting holes are formed on the step to realize the detachable connection between the support plate 32 and the bracket 3. The corresponding support plate 32 can be selected for support according to the model of the glass, thereby improving the versatility of the turntable device.
