[0039] Example
[0040] Hot-bent glass is curved glass produced by heating and softening flat glass in a mold, followed by annealing. Different hot-bending equipment is typically selected depending on the processing scale and type. In smaller processing equipment with a smaller batch size, the molds are usually fixed. The glass is heated in a sealed cavity and then pressed together by the upper and lower molds to achieve the hot bending process. In larger-scale glass hot-bending processes, multiple molds are placed in a heating station, with flat glass placed on top. A heating hood with a cavity is then lowered, allowing the glass to soften and eventually sag under gravity to form a shape that fits the mold. However, traditional hot-bending equipment suffers from low efficiency. This is mainly because each batch of glass requires heating and softening followed by a holding time to complete the hot bending process. Otherwise, rapid cooling can affect the glass quality or even cause damage. This process is time-consuming, limiting production efficiency. To address these technical problems, this embodiment provides the following technical solution:
[0041] For details, please see Figures 1-5 This embodiment provides a high-efficiency glass hot bending equipment, including a gantry frame 10 extending along a first direction and a slide rail 40. The gantry frame 10 is provided with a first heat preservation station 11, a heating station 12 and a second heat preservation station 13 in sequence along the first direction.
[0042] Specifically, each workstation is equipped with a lifting drive assembly, and the first insulation workstation 11 and the second insulation workstation 13 are each equipped with an insulation cover 21, which is connected to the lifting drive assembly; the heating workstation 12 is equipped with a heat insulation cover 22, which is connected to the lifting drive assembly on the heating workstation 12.
[0043] Specifically, two heating bases 30 are provided on the slide rail 40, and a transverse drive assembly is provided below the heating base 30 to abut against the slide rail 40. The transverse drive assembly is adapted to drive the heating base 30 to move along the first direction; a heating module is provided on the heating base 30.
[0044] The coverage area of the heat insulation cover 21 and the heat insulation cover 22 is smaller than the coverage area of the heating base 30, and the heat insulation cover 21 and the heat insulation cover 22 are adapted to abut against the top surface of the heating base 30.
[0045] In the above scheme, the worker places the hot bending mold on the heating base 30, and then places the glass to be hot bent on the hot bending mold; one of the heating bases 30 moves along the first direction to the heating station 12, and the lifting drive component drives the heat insulation cover 22 to cover the current heating base 30. The heating module on the heating base 30 heats the glass, causing the temperature inside the heat insulation cover 22 to gradually rise, thus achieving hot bending of the glass. At this time, the worker can load the glass onto the other heating base 30. After the glass currently located at the heating station 12 has completed hot bending, the glass located at the heating station 12 is first transferred to the second heat preservation station. 13. The lifting drive assembly on the second insulation station 13 drives the insulation cover 21 to cover the heating base 30, realizing the slow cooling of the glass. At the same time, the heating base 30 located on the first insulation station 11 moves along the first direction into the heating station 12, thereby realizing a rapid switching connection. After the glass on the second insulation station 13 has been cooled down, it can be unloaded, and then the next piece of glass that needs to be hot-bent can be loaded and unloaded, and the above process is repeated. This solution can effectively improve the efficiency of glass hot bending and effectively increase production capacity by setting two insulation stations and placing the heating station 12 between the two insulation stations.
[0046] For details, please see Figure 3 The transverse drive assembly includes a rotary drive 51 and a drive roller 52. There are three drive rollers 52. The rotary drive 51 is adapted to drive at least one roller 52 to rotate.

[0048] In some embodiments, the three rolling elements 52 are rollers; in other embodiments, the three rolling elements 52 include a gear and two rollers.
[0049] In the above scheme, the rotary drive 51 can drive at least one rolling element 52 to rotate, and the rolling element 52 moves by cooperating with the slide rail 40. It is understood that in some implementations, the rolling element 52 may include a gear, and a rack is further provided on the slide rail 40. Furthermore, the three rolling elements 52 may be a combination of gear and roller, that is, including one gear and two rollers.
[0050] For details, please see Figure 2 The heat insulation cover 22 includes a main cover 225 and a removable extension ring 226 located below the main cover 225;
[0051] Furthermore, a plurality of first mounting ears 2251 are provided around the outer wall of the main cover 225, and a plurality of second mounting ears 2261 corresponding to the positions of the first mounting ears 2251 are provided around the outer wall of the extension ring 226.
[0052] Specifically, it also includes a fastener 227 suitable for securing the first mounting ear 2251 and the second mounting ear 2261;
[0053] In the above solution, in order to ensure that the heat inside the heat insulation cover 22 can be fully utilized, the space of the heat insulation cover should be minimized as much as possible, that is, it should be able to accommodate the glass mold and the glass. However, in some application scenarios, changes in the mold and the processing requirements of the glass result in a certain increase in the required space. This solution can effectively solve this problem. Workers can further install extension rings 226 to increase the covering space of the heat insulation cover 22, and remove them when not needed. This allows for flexible control of the covering space of the heat insulation cover 22, and better realization of the hot bending process of the glass.
[0054] Specifically, the lifting drive assembly includes the gantry crane 14;
[0055] Furthermore, lifting lugs are provided at the four corners of the top surface of the heat insulation cover 21 and the heat insulation cover 22;
[0056] In the above scheme, the gantry crane 14 is installed on the gantry frame 10, and the lifting and lowering of the thermal insulation cover 21 or the heat insulation cover 22 is achieved by acting on the lifting lugs.
[0057] For details, please see Figure 5 Multiple fireproof bricks are provided on the heating base 30, and the multiple fireproof bricks are stacked to form multiple matrix-arranged grooves 31;
[0058] Furthermore, the heating module includes a heating wire 32, which is disposed within the groove 31;
[0059] In the above scheme, the fireproof bricks themselves have sufficient supporting strength to support the weight of the hot bending mold and the glass, and also have good fireproof performance; this scheme forms a groove 31 that can accommodate the heating wire 32 by arranging the fireproof bricks in a reasonable way, which can form a good space to accommodate the heating wire 32.
[0060] Specifically, the insulation cover 21 includes, from the inside out, a steel wire fixing layer 221, an insulation layer 222, a heat insulation layer 223, and an outer protective layer 224.
[0061] Furthermore, the insulation layer 222 is made of flame-retardant insulation cotton, and the steel wire fixing layer 221 is formed by steel wires woven into a mesh.
[0062] In one embodiment, the heat insulation layer 223 is made of ceramic fiber material.
[0063] In one embodiment, the outer protective layer 224 is a steel plate.
[0064] In the above scheme, this scheme further improves the insulation cover 21. The steel wire fixing layer 221 is made of woven steel wire, which can realize the physical fixation of the multi-layer structure and ensure the connection strength. The insulation layer 222 is made of flame-retardant insulation cotton, which has both excellent flame-retardant and insulation performance. It improves the insulation performance of the insulation cover 21 while ensuring the safety of use. Furthermore, this scheme also sets up a heat insulation layer 223 made of ceramic fiber material in addition to the insulation layer 222 to further improve the heat insulation performance, thereby helping to improve the insulation performance. The ceramic fiber material itself also has excellent flame-retardant properties, so it can further ensure the safety of use.
[0065] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any way.
