[0066] The glass hot bending furnace provided in this embodiment allows for the overall raising and lowering of all lamp tube assemblies 150 and the second lifting assembly 160, which are supported by a first lifting component 130 and mounted on an assembly plate 140. This facilitates opening up the internal accommodating space of the hot bending furnace body 110 and allows for the overall adjustment of the positions of all lamp tube assemblies 150. On the assembly plate 140, each lamp tube assembly 150 is fitted with a second lifting assembly 160, enabling the adjustment of the position of each lamp tube assembly 150 relative to the hot bending furnace body 110.

[0067] like Figures 1 to 5 As shown, in one feasible embodiment, the first lifting assembly 130 includes: a first motor 131, which is mounted on the support frame 120; a first rolling shaft 132, the output end of the first motor 131 being connected to the first rolling shaft 132; and a first lead screw 133, one end of which is connected to the first rolling shaft 132 via a transmission component, and the other end of which is connected to the assembly plate 140.

[0068] In this technical solution, the structure of the first lifting component 130 is further provided. The first lifting component 130 may include a first motor 131, a first rolling shaft 132 and a first lead screw 133. The output end of the first motor 131 is connected to the first rolling shaft 132, and the first rolling shaft 132 is connected to the first lead screw 133. By rotating the first lead screw 133, the assembly plate 140 can be driven to rise or fall, thereby driving all the lamp tube assemblies 150 and the second lifting component 160 to rise or fall in unison.

[0069] It is understandable that the support frame 120 can be gantry-shaped. The first motor 131 is mounted on the crossbeam of the support frame 120. The first rolling shaft 132 is arranged along the length of the crossbeam, while the first lead screw 133 is arranged along the vertical direction of the support frame 120. A transmission component can be arranged between the first lead screw 133 and the first rolling shaft 132 to change the driving direction, such as a bevel gear 163.

[0070] like Figures 1 to 5 As shown, in one feasible embodiment, each second lifting assembly 160 includes: a second motor 161 disposed on the mounting plate 140; a second rolling shaft 162, the output end of the second motor 161 being connected to the second rolling shaft 162; a gear 163 disposed on the second rolling shaft 162; and a chain 164 meshing with the gear 163 and connected to the lamp assembly 150.

[0071] In this technical solution, the structure of the second lifting assembly 160 is further improved. The second lifting assembly 160 may include a second motor 161, a second rolling shaft 162, a rack and pinion, and a chain 164. Based on this, during operation, by turning on the second motor 161, the second motor 161 drives the gear 163 to rotate through the second rolling shaft 162. In turn, the gear 163 drives the chain 164 to rotate. The chain 164 is connected to the lamp tube assembly 150, which allows the lamp tube assembly 150 to be lifted or lowered.

[0072] like Figures 1 to 5 As shown, in one possible implementation, each lamp assembly 150 includes: a fixing plate 151 connected to the second lifting assembly 160; a pull rod 152, one end of which is connected to the fixing plate 151; and a lamp tube 153 connected to the other end of the pull rod 152.

[0073] In this technical solution, the structural composition of each lamp assembly 150 is further provided. The lamp assembly 150 may include a fixing plate 151, a pull rod 152 and a lamp 153. The lamp 153 is connected to the fixing plate 151 through the pull rod 152. The fixing plate 151 is then connected to the second lifting assembly 160. The second lifting assembly 160 can lift or lower the fixing plate 151 to drive the lamp 153 to rise or fall. The pull rod 152 facilitates the adjustment of the lamp 153's position, making it easier to position the lamp 153 within the hot bending furnace body 110.

[0074] like Figures 1 to 5As shown, in one feasible embodiment, each lamp assembly 150 further includes: a temperature sensor 154; two levers 152, each lever 152 connected to a lamp 153; one end of the temperature sensor 154 is connected to a fixing plate 151, and the other end is arranged between two adjacent lamps 153; and a safety probe 155, one end of which is connected to the fixing plate 151, and the other end extends through two adjacent lamps 153.

[0075] In this technical solution, the structural composition of each lamp tube assembly 150 is further provided. Each lamp tube assembly 150 may also include a temperature sensor 154 and a safety probe 155. The temperature sensor 154 is set to facilitate the determination of the temperature of the lamp tube 153. The safety probe 155 is set to facilitate the determination of the positional relationship between the lamp tube 153 and the glass to be bent. When the probe contacts the glass to be bent, an alarm can be issued to avoid the lamp tube 153 from dropping unexpectedly, thereby causing damage to the lamp tube 153.

[0076] like Figures 1 to 5 As shown, in one feasible embodiment, the hot bending furnace body 110 includes: a housing 111; a plurality of observation windows 112, the plurality of observation windows 112 being arranged at intervals on the housing 111; wherein, a plurality of lamp tube assemblies 150 are arranged along the length direction of the housing 111; and a blower 113, the output end of the blower 113 being connected to the housing 111.

[0077] In this technical solution, the structural composition of the hot bending furnace body 110 is further provided. The hot bending furnace body 110 may include a box 111 and multiple observation windows 112. The arrangement of the lamp tubes 153 inside the box 111 is conveniently known through the setting of multiple observation windows 112.

[0078] like Figures 1 to 5 As shown, in one feasible embodiment, the glass hot bending furnace further includes: a guide rail 170, which is disposed inside the support frame 120; a roller 180, which is disposed at the bottom of the hot bending furnace body 110; a third motor 190, the output end of which is connected to the roller 180; and an electrical control cabinet 200, which is disposed on one side of the support frame 120 and is communicatively connected to the first lifting assembly 130 and the second lifting assembly 160.

[0079] In this technical solution, the glass hot bending furnace may also include a guide rail 170, a third motor 190, and a rolling wheel 180. The hot bending furnace body 110 is slidably mounted on the guide rail 170 via the rolling wheel 180. By turning on the third motor 190, the third motor 190 can drive the rolling wheel 180 to rotate, thereby allowing the hot bending furnace body 110 to slide on the guide rail 170. When the first lifting component 130 drives multiple lamp tube components 150 and the second lifting component 160 to lift as a whole, the third motor 190 can be used to drive the hot bending furnace body 110 to detach from the area of ​​the support frame 120, making it easier to place the glass to be bent and the mold into the hot bending furnace body 110, thus making the use of the glass hot bending furnace more convenient.

[0080] In this technical solution, the electrical control cabinet 200 allows for the unified assembly of the electrical control devices of the first lifting assembly 130 and the second lifting assembly 160.

[0081] like Figure 6 As shown, a glass hot bending method is proposed according to a second aspect of the embodiments of this application, applied to a glass hot bending furnace as described in any of the above technical solutions. The glass hot bending method includes:

[0082] Step 201: Place the hot bending mold inside the hot bending furnace body;

[0085] Step 204: Turn on the lamp assembly. When the lamp assembly reaches the baking temperature, control the second lifting component to adjust the position of the lamp assembly based on the reference position information.

[0086] The glass hot bending method provided in this application embodiment, since it is applied to the glass hot bending furnace of any of the above-described technical solutions, therefore possesses all the beneficial effects of the glass hot bending furnace of the above-described technical solutions.

[0087] The glass hot bending method provided in this application first uses a second lifting component to adjust the position of the lamp tube assembly to obtain reference position information, and then lifts all the lamp tube assemblies.
