Description

Technical Field

[0001] This invention belongs to the field of glass tempering technology, specifically a glass tempering equipment and process. Background Technology

[0002] Glass tempering is a glass processing technique that uses physical or chemical methods to create uniform compressive stress on the glass surface, thereby improving its mechanical strength and thermal stability. Tempered glass typically has 3-5 times the bending and impact resistance of ordinary glass, and if it breaks, it shatters into small, obtuse-angled particles, making it highly safe. Therefore, it is also known as safety glass. Due to its high strength and breakage safety, special tempered glass is widely used in aerospace, automotive, and marine industries, such as aircraft windows, high-speed train windshields, and ship bridge observation windows, to meet the protection and visibility requirements under harsh working conditions.

[0003] Existing technologies disclose several invention patents in the field of glass tempering, including patent CN115259644B, which discloses an air grating fixing device for glass tempering equipment and the glass tempering equipment itself. The glass tempering equipment is used to temper horizontally arranged glass. The air grating is connected to the glass tempering equipment via a corresponding air grating fixing device. The air grating fixing device includes a fixing plate, a fixing bracket, and an air guide pipe. The fixing plate is used to connect to the tempering equipment and has an air outlet. The air grating has an air inlet, and the air inlet and outlet are connected by the air guide pipe. One end of the fixing bracket is fixedly connected to the fixing plate, and the air grating is detachably connected to the end of the fixing bracket away from the fixing plate. This invention, through the air grating fixing device, allows the application of air gratings originally used in vertical tempering furnaces to tempering equipment in horizontal tempering furnaces. This enables the production of curved glass products that were originally produced in vertical tempering furnaces using horizontal tempering furnaces, significantly improving production efficiency.

[0004] Existing glass tempering air grilles typically consist of multiple independent small air boxes, each with several vertically adjustable air outlet pipes underneath. These air outlet pipes are adjusted in height by rotation. During glass tempering, the distance between each air outlet pipe and the glass model needs to be adjusted individually according to the model's shape to ensure uniform cooling. However, due to the large number of air outlet pipes and the fact that all adjustments are done manually, the entire adjustment process is time-consuming and inefficient. Furthermore, some air outlet pipes cannot be closed during tempering, resulting in significant waste of cooling energy and further reducing the equipment's operational economy.

[0005] Based on this, the present invention designs a glass tempering equipment and process to solve the above problems. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies, this invention proposes a glass tempering equipment and process. This invention primarily addresses the problem that existing glass tempering air ducts typically consist of multiple independent small air boxes, each with several vertically adjustable air outlet pipes below it. These air outlet pipes are adjusted in height by rotation. During glass tempering, the distance between each air outlet pipe and the glass model needs to be adjusted individually according to the model's shape to ensure uniform cooling. However, due to the large number of air outlet pipes and the fact that all adjustments are done manually, the entire adjustment process is time-consuming and inefficient. Furthermore, some air outlet pipes cannot be closed during tempering, resulting in significant waste of cooling energy and further reducing the equipment's operational economy.

Multiple second implantation holes are opened on the second air box at the positions of multiple first implantation holes. A second air duct is slidably fitted in each second implantation hole. Multiple second air ducts located in the same horizontal row are connected by a second linkage frame. A transmission mechanism is provided between the first linkage frame and the second linkage frame to enable the first linkage frame to drive the second linkage frame to move synchronously.

[0008] Preferably, the top of the wind grid frame has a first transmission port, and the transmission mechanism is disposed in the first transmission port. The transmission mechanism includes a first support plate fixedly connected to the inner side wall of the first transmission port. A first gear and a second gear can be detachably installed on the first support plate at the position corresponding to each first linkage frame. The first gear meshes with a first toothed plate provided on the first linkage frame, and the second gear meshes with a second toothed plate provided on the second linkage frame, so that the first linkage frame can drive the second linkage frame to move synchronously through the transmission of the first gear and the second gear.

[0009] Preferably, each of the second linkage frames is equipped with a third adapter frame, one end of the second hydraulic cylinder is rotatably connected to the third adapter frame, and the other end of the second hydraulic cylinder is rotatably connected to a fourth adapter frame. The fourth adapter frame is fixedly installed at the bottom of the second air box, wherein the rated hydraulic strength of the second hydraulic cylinder is less than the rated hydraulic strength of the first hydraulic cylinder.

[0010] Preferably, each of the No. 1 and No. 2 air ducts has multiple air inlets on its wall, and each air inlet is arranged in a ring array along the circumference of the corresponding No. 1 or No. 2 air duct.

[0011] Preferably, both the No. 1 and No. 2 wind boxes are provided with flange joints on their rear ends for introducing cooling gas required for glass tempering into the No. 1 and No. 2 wind boxes.

[0012] Preferably, each of the first and second linkage frames is equipped with a linkage shaft at its end, and the top of the wind grid frame is provided with a second transmission port. A linkage plate is provided in the second transmission port. The linkage plate is slidably engaged with the first and second linkage frames in the same vertical direction, and multiple linkage ports are correspondingly provided on the linkage plate. The two linkage shafts are respectively movably connected to the corresponding linkage ports. A directional shaft is also fixedly connected to the linkage plate. The other end of the directional shaft is slidably sleeved inside the directional sleeve. The directional sleeve is fixedly connected to the second support plate. The second support plate is installed on the inner side wall of the second transmission port.

[0013] Preferably, a No. 5 adapter is fixedly connected to the linkage plate, one end of a No. 3 hydraulic cylinder is rotatably connected to the No. 5 adapter, the other end of the No. 3 hydraulic cylinder is rotatably connected to a No. 6 adapter, and the No. 6 adapter is fixedly installed on the No. 2 support plate. The rated hydraulic strength of the No. 3 hydraulic cylinder is less than the rated hydraulic strength of the No. 2 hydraulic cylinder.

[0014] Preferably, an adapter sleeve is rotatably fitted on the linkage shaft, and the linkage shaft is tumbledly connected to the linkage port through the adapter sleeve. The inner sidewall of the adapter sleeve has multiple lubrication grooves, and each lubrication groove is provided with a lubrication column. One end of the lubrication column abuts against the shaft surface of the linkage shaft, and the other end has a directional groove. A directional column is slidably connected in the directional groove. One end of the directional column is connected to the inner sidewall of the directional groove, and a compensation spring is fitted around it. The lubrication column is elastically supported and connected to the inner sidewall of the directional groove through the compensation spring.

[0015] A glass tempering process includes: The system independently controls multiple No. 1 hydraulic cylinders according to the curvature of the glass to drive the No. 1 linkage frame and No. 1 air duct to rise and fall. At the same time, through the gear and tooth plate transmission mechanism, it drives the No. 2 linkage frame and No. 2 air duct to move synchronously in the opposite direction, so as to achieve equidistant following between the upper and lower air grilles and the glass surface. By replacing the transmission gears with different diameters, the speed ratio of the upper and lower air ducts can be changed to adapt to the different cooling requirements of glass of different specifications and optimize stress distribution. The system synchronously controls hydraulic cylinder No. 1 and hydraulic cylinder No. 2. Among them, hydraulic cylinder No. 2 has a lower rated pressure and only provides auxiliary thrust to achieve smooth operation of the upper and lower air grilles in master-slave cooperative mode. When the No. 1 and No. 2 air ducts are raised and lowered, the air inlets on their side walls will move out of or into the No. 1 or No. 2 air box, thereby opening or closing the cooling airflow path to achieve synchronous air supply or zoned shutdown, so as to save air source. The linkage shafts at the ends of the linkage frame are coupled through the same linkage plate and slide synchronously under the guidance of the directional shaft and the sleeve to ensure the consistency of the up and down movement; During the movement, the No. 3 hydraulic cylinder continuously applies pressure, causing the linkage shaft to fit tightly against the wall of the linkage plate hole, eliminating transmission gaps and improving movement accuracy and stability.

[0016] The beneficial effects of this invention are as follows: 1. In this invention, the coordinated movement of the first and second air ducts ensures the consistency of the distance between the cooling air grid and the upper and lower surfaces of the glass, making the airflow impact force on the upper and lower surfaces of the glass more uniform. Uniform cooling helps to reduce the uneven stress inside the glass during the tempering process, thereby improving the tempering quality and yield. By changing the transmission ratio of the first and second gears, the movement speed of the upper and lower air ducts at different cooling stages can be adjusted, thereby optimizing the cooling curve of the glass and improving the tempering stress distribution.

[0017] 2. In this invention, the system can automatically adjust the spacing between the upper and lower air grilles according to the height change of the curved glass, which can adapt to the tempering and cooling requirements of curved glass with different curvatures. By changing the wheel diameter of the first gear and the second gear, the transmission ratio between the first linkage frame and the second linkage frame can be changed, so as to realize the deceleration or acceleration of the second air duct relative to the first air duct, thereby enhancing the adaptability of the equipment to glass of different specifications.

[0018] 3. In this invention, a transmission mechanism is adopted, combined with the coordinated control of hydraulic cylinders No. 1 and No. 2, to ensure that linkage frame No. 1 and No. 2 can operate in conjunction with a preset relationship. This achieves coordinated and precise adjustment of the upper and lower air grilles. When the system controls the movement of air duct No. 1 and No. 2 to a specific position, the air inlets of air duct No. 1 and No. 2 can be fully exposed simultaneously, ensuring that the upper and lower surfaces of the glass are simultaneously impacted by the cooling airflow. This avoids uneven cooling caused by asynchronous opening. By controlling the movement of air duct No. 1 and No. 2 to block the air inlets, individual air ducts No. 1 and No. 2 can be closed, thereby saving the low-temperature gas required during the glass cooling process and reducing energy consumption.

[0019] 4. In this invention, the linkage shaft is tightly attached to the linkage port by the guidance of the linkage plate, the directional shaft and the directional sleeve, and the continuous thrust of the No. 3 hydraulic cylinder. This effectively eliminates the transmission gap caused by machining or assembly errors, avoids idle stroke and impact during movement, reduces vibration, and makes the transmission process smoother. Speed ​​ratio adjustment can be achieved by replacing the No. 1 and No. 2 gears without the need for additional drive sources or complex control systems. The structure is simple and reliable, and the cost is low. The thrust of the No. 3 hydraulic cylinder can adaptively compensate for changes in the fit clearance caused by wear or temperature changes. While maintaining long-term stable synchronous performance, it is beneficial to extend the service life of the equipment.

[0020] 5. In this invention, the rated hydraulic strength of the No. 2 hydraulic cylinder is less than that of the No. 1 hydraulic cylinder, which reflects the difference in the driving requirements of the upper and lower wind gates. The No. 1 linkage frame adopts a strong driving force because it bears a larger load or needs to overcome more resistance, while the No. 2 linkage frame can meet the synchronization requirements with a smaller driving force, thus realizing the optimized configuration of the driving scheme.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 13As shown, a glass tempering equipment includes a frame 1, with a roller conveyor 4 embedded inside the frame 1. A tempering furnace 2, a buffer chamber 3, and a cooling chamber 5 are sequentially installed on the top of the frame 1 along the conveying direction of the roller conveyor 4. An air grid frame 6 is provided inside the cooling chamber 5. A first air box 7 is installed above the conveying surface of the roller conveyor 4 on the inner top of the air grid frame 6. The first air box 7 has multiple first implantation holes. A first air pipe 8 is slidably fitted in each first implantation hole. Multiple first air pipes 8 located in the same horizontal row are connected by a first linkage frame 12. A first adapter frame 9 is installed at the front end of the first linkage frame 12. One end of a first hydraulic cylinder 10 is rotatably connected to the first adapter frame 9. The other end of the first hydraulic cylinder 10 is rotatably connected to a second adapter frame 11. The second adapter frame 11 is fixed to the top of the first air box 7. A second air box 19 is installed on the bottom inner side of the air grate frame 6, corresponding to the lower part of the roller conveyor 4. Multiple second implantation holes are opened on the second air box 19 at the positions of multiple first implantation holes. A second air duct 20 is slidably fitted in each second implantation hole. Multiple second air ducts 20 located in the same horizontal row are connected by a second linkage frame 21. A transmission mechanism is provided between the first linkage frame 12 and the second linkage frame 21 to enable the first linkage frame 12 to drive the second linkage frame 21 to move synchronously.

[0025] Specifically, a transmission port 13 is opened at the top of the wind grid frame 6, and a transmission mechanism is set in the transmission port 13. The transmission mechanism includes a support plate 14 fixedly connected to the inner side wall of the transmission port 13. A gear 16 and a gear 17 can be detachably installed on the support plate 14 at the position corresponding to each linkage frame 12. The gear 16 meshes with the toothed plate 15 on the linkage frame 12, and the gear 17 meshes with the toothed plate 18 on the linkage frame 21, so that the linkage frame 12 can drive the linkage frame 21 to move synchronously through the transmission of the gear 16 and the gear 17.

[0026] Specifically, in this embodiment: the No. 1 wind box 7 and the No. 2 wind box 19 are connected to a low-temperature air source for glass tempering cooling via their flange joints 26. When the roller conveyor 4 transports the high-temperature glass into the cooling chamber 5, the system sends different control commands to multiple No. 1 hydraulic cylinders 10 according to the height change of the curved glass, driving each No. 1 hydraulic cylinder 10 to perform corresponding extension and retraction actions. During the action, one end of the No. 1 hydraulic cylinder 10 rotates around the No. 2 adapter frame 11, and the other end rotates around the No. 1 adapter frame 9, and transmits the force to the connected No. 1 linkage frame 12 through the No. 1 adapter frame 9, thereby driving multiple No. 1 air ducts 8 on the No. 1 linkage frame 12 to rise and fall synchronously. At the same time, the No. 1 linkage frame 12 drives the No. 1 gear plate 15 on it to move synchronously. The No. 1 gear plate 15 drives the No. 1 gear 16 meshing with it to rotate. The No. 1 gear 16 drives the No. 2 gear plate 18 and the connected No. 2 gear 17 through the No. 2 gear 18. The first linkage frame 21 moves synchronously, thereby enabling multiple second air ducts 20 on the second linkage frame 21 to move up and down in tandem with multiple first air ducts 8 on the first linkage frame 12. A transmission mechanism consisting of a first gear plate 15, a first gear 16, a second gear 17, and a second gear plate 18 connects the first linkage frame 12 and the second linkage frame 21, ensuring that the first air ducts 8 and the second air ducts 20 always move synchronously and in opposite directions during the adjustment process. This ensures that the spacing between the cooling air vents and the upper and lower surfaces of the glass is consistent. Through the cooperation of the first hydraulic cylinder 10 and the transmission mechanism, the spacing between the upper and lower air vents is automatically adjusted according to the curvature of the glass, which can adapt to the cooling requirements of curved glass with different curvatures. The equidistant following of the first air ducts 8 and the second air ducts 20 with the glass surface makes the airflow impact force on the upper and lower surfaces of the glass more uniform, which helps to reduce the uneven stress during the tempering process and improve the quality of glass tempering.

[0027] Specifically, each No. 2 linkage frame 21 is equipped with a No. 3 adapter frame 22. One end of the No. 2 hydraulic cylinder 23 is rotatably connected to the No. 3 adapter frame 22, and the other end of the No. 2 hydraulic cylinder 23 is rotatably connected to the No. 4 adapter frame 24. The No. 4 adapter frame 24 is fixedly set at the bottom of the No. 2 air box 19. The rated hydraulic strength of the No. 2 hydraulic cylinder 23 is less than the rated hydraulic strength of the No. 1 hydraulic cylinder 10.

[0028] Specifically, the diameters of gear 16 and gear 17 can be selected and replaced according to the curvature and thickness of the curved glass to be processed, so that the multiple second-level air ducts 20 on the second-level linkage frame 21 can achieve deceleration or acceleration relative to the multiple first-level air ducts 8 on the first-level linkage frame 12. By replacing gear 16 and gear 17 with different diameters, the transmission ratio between the first-level linkage frame 12 and the second-level linkage frame 21 can be changed, thereby adjusting the speed of the second-level air duct 20 relative to the first-level air duct 8. This enhances the adaptability of the equipment to glass of different specifications. When the second-level air duct 20 decelerates or accelerates, the airflow impact intensity and time on the upper and lower surfaces of the glass at different cooling stages can be adjusted, thereby optimizing the cooling curve of the glass and improving the tempering stress distribution. No additional drive source or complex control system is required. The proportional adjustment of the speed of the first-level air duct 8 and the second-level air duct 20 can be achieved simply by changing the diameters of gear 16 and gear 17. The structure is simple, reliable, and low in cost.

[0029] Specifically, each of the No. 1 air duct 8 and the No. 2 air duct 20 has multiple air inlets 25 on its duct wall, and each air inlet 25 is arranged in a ring array along the circumference of the corresponding No. 1 air duct 8 or No. 2 air duct 20.

[0030] Specifically, this implementation involves controlling hydraulic cylinder 10 to extend, while simultaneously controlling hydraulic cylinder 23 to extend synchronously. During this movement, one end of hydraulic cylinder 23 rotates around adapter 4, and the other end rotates around adapter 3. The thrust is transmitted to the connected linkage 21 via adapter 3. The rated hydraulic strength of hydraulic cylinder 23 is less than that of hydraulic cylinder 10. By controlling hydraulic cylinder 10 and hydraulic cylinder 23 to move synchronously, the coordinated adjustment of the upper and lower air grates is achieved, ensuring that linkage 12 and linkage 21 can operate in conjunction according to a preset relationship. Setting the rated hydraulic strength of hydraulic cylinder 23 to be less than that of hydraulic cylinder 10 reflects the difference in driving requirements between the upper and lower air grates. Linkage 12 needs to bear a larger load or overcome more resistance, while linkage 21 can meet the synchronous movement requirements with a hydraulic cylinder of smaller driving force.

[0031] Specifically, both the No. 1 wind box 7 and the No. 2 wind box 19 are equipped with flange joints 26 on their rear ends for introducing cooling gas required for glass tempering into the No. 1 wind box 7 and the No. 2 wind box 19.

[0032] Specifically, during the movement of the first linkage frame 12 and the second linkage frame 21, the linkage shafts 36 at their ends slide within two corresponding linkage ports 30 on the same linkage plate 29. The two linkage shafts 36 together drive the linkage plate 29 to move, thereby causing the directional shaft 31 connected to the linkage plate 29 to slide within the directional sleeve 32. This ensures the synchronicity and consistency of the movement of the two linkage shafts 36. By connecting the two linkage shafts 36 through the same linkage plate 29 and with the guidance of the directional shaft 31 and the directional sleeve 32, it is ensured that the first linkage frame 12 and the second linkage frame 21 remain synchronized during the movement, avoiding jamming or transmission failure caused by asynchronous movement. The linkage plate 29, as an intermediate force transmission component, couples the movement of the two linkage shafts 36 together. Combined with the directional guide structure, the entire transmission process is made smoother, reducing vibration and impact, which is beneficial to improving the reliability and service life of the equipment.

[0033] Specifically, each of the first linkage frame 12 and the second linkage frame 21 is equipped with a linkage shaft 36 at its end. The top of the air grid frame 6 is provided with a second transmission port 27. A linkage plate 29 is provided in the second transmission port 27. The linkage plate 29 is slidably engaged with the first linkage frame 12 and the second linkage frame 21 which are in the same vertical direction. A plurality of linkage ports 30 are provided on the linkage plate 29. The two linkage shafts 36 are respectively movably connected to the corresponding linkage ports 30. A directional shaft 31 is also fixedly connected to the linkage plate 29. The other end of the directional shaft 31 is slidably sleeved in the directional sleeve 32. The directional sleeve 32 is fixedly connected to the second support plate 28. The second support plate 28 is installed on the inner wall of the second transmission port 27.

[0034] Specifically, during the movement of the first linkage frame 12 and the second linkage frame 21, the linkage shafts 36 at their ends slide within two corresponding linkage ports 30 on the same linkage plate 29. The two linkage shafts 36 together drive the linkage plate 29 to move, thereby causing the directional shaft 31 connected to the linkage plate 29 to slide within the directional sleeve 32. This ensures the synchronicity and consistency of the movement of the two linkage shafts 36. By connecting the two linkage shafts 36 through the same linkage plate 29 and with the guidance of the directional shaft 31 and the directional sleeve 32, it is ensured that the first linkage frame 12 and the second linkage frame 21 remain synchronized during the movement, avoiding jamming or transmission failure caused by asynchronous movement. The linkage plate 29, as an intermediate force transmission component, couples the movement of the two linkage shafts 36 together. Combined with the directional guide structure, the entire transmission process is made smoother, reducing vibration and impact, which is beneficial to improving the reliability and service life of the equipment.

[0035] Specifically, a No. 5 adapter frame 33 is fixedly connected to the linkage plate 29, one end of the No. 3 hydraulic cylinder 34 is rotatably connected to the No. 5 adapter frame 33, and the other end of the No. 3 hydraulic cylinder 34 is rotatably connected to the No. 6 adapter frame 35. The No. 6 adapter frame 35 is fixedly installed on the No. 2 support plate 28. The rated hydraulic strength of the No. 3 hydraulic cylinder 34 is less than the rated hydraulic strength of the No. 2 hydraulic cylinder 23.

[0036] Specifically, in this embodiment, during the process of the linkage plate 29 driving the directional shaft 31 to slide within the directional sleeve 32, the system controls the third hydraulic cylinder 34 to perform an extension movement. Under the pushing action of the third hydraulic cylinder 34, the two linkage shafts 36 always remain in contact with the inner sidewall of the corresponding linkage port 30, thereby further improving the synchronicity of the movement of the two linkage shafts 36. Through the continuous thrust of the third hydraulic cylinder 34, the two linkage shafts 36 are always tightly attached to the inner sidewall of the linkage port 30, effectively eliminating the transmission gap caused by machining or assembly errors, avoiding idle stroke and impact during the movement. The thrust of the third hydraulic cylinder 34 can be adjusted according to the actual working conditions, and can adaptively compensate for the changes in the fit clearance caused by wear or temperature changes, extending the service life of the equipment while maintaining long-term stable synchronization performance.

[0037] Specifically, a transition sleeve 37 is rotatably sleeved on the linkage shaft 36. The linkage shaft 36 is rotatably connected to the linkage port 30 through the transition sleeve 37. Multiple lubrication grooves 38 are provided on the inner side wall of the transition sleeve 37. Each lubrication groove 38 is provided with a lubrication column 39. One end of the lubrication column 39 abuts against the shaft surface of the linkage shaft 36, and the other end is provided with a directional groove 40. A directional column 41 is slidably connected in the directional groove 40. One end of the directional column 41 is connected to the inner side wall of the directional groove 40, and a compensation spring 42 is sleeved around it. The lubrication column 39 is elastically supported and connected to the inner side wall of the directional groove 40 through the compensation spring 42.

[0038] A glass tempering process includes: According to the curvature of the glass, the system independently controls multiple No. 1 hydraulic cylinders 10 to drive the No. 1 linkage frame 12 and the No. 1 air duct 8 to rise and fall. At the same time, through the gear and tooth plate transmission mechanism, it drives the No. 2 linkage frame 21 and the No. 2 air duct 20 to move synchronously in the opposite direction, so as to achieve equidistant following between the upper and lower air grilles and the glass surface. By replacing the transmission gears with different diameters, the speed ratio of the upper and lower air ducts can be changed to adapt to the different cooling requirements of glass of different specifications and optimize stress distribution. The system synchronously controls hydraulic cylinder 10 and hydraulic cylinder 23. Hydraulic cylinder 23 has a lower rated pressure and only provides auxiliary thrust to achieve smooth operation of the upper and lower air grilles in master-slave cooperative mode. When the No. 1 air duct 8 and the No. 2 air duct 20 are raised or lowered, the air inlet 25 on their side walls will move out or into the No. 1 air box 7 or the No. 2 air box 19, thereby opening or closing the cooling airflow passage, realizing synchronous air supply or zoned shutdown, so as to save air source. The linkage shaft 36 at the end of the linkage frame is coupled through the same linkage plate 29 and slides synchronously under the guidance of the directional shaft 31 and the sleeve to ensure the consistency of the up and down movement; During the movement, hydraulic cylinder 34 continuously applies pressure, causing the linkage shaft 36 to fit tightly against the hole wall of linkage plate 29, eliminating transmission gaps and improving movement accuracy and stability.

[0039] During operation, the No. 1 wind box 7 and the No. 2 wind box 19 are connected to the low-temperature air source for glass tempering and cooling through their flange joints 26. When the roller conveyor 4 transports the high-temperature glass into the cooling chamber 5, the system sends different control commands to multiple No. 1 hydraulic cylinders 10 according to the height change of the curved glass, driving each No. 1 hydraulic cylinder 10 to perform the corresponding extension and retraction actions. During operation, one end of hydraulic cylinder 10 rotates around adapter frame 11, and the other end rotates around adapter frame 9. The force is transmitted to the connected linkage frame 12 via adapter frame 9, causing multiple air ducts 8 on the linkage frame 12 to rise and fall synchronously. Simultaneously, the linkage frame 12 drives the gear plate 15 on it to move synchronously. The gear plate 15 drives the meshing gear 16 to rotate. The gear 16, through gear 17, drives the gear plate 18 and its connected gears 18 to rotate. The first linkage frame 21 moves synchronously, thereby enabling multiple second air ducts 20 on the second linkage frame 21 and multiple first air ducts 8 on the first linkage frame 12 to move up and down in tandem. Through the cooperation of the first hydraulic cylinder 10 and the transmission mechanism, the distance between the upper and lower air ducts is automatically adjusted according to the curvature of the glass, ensuring that the first air duct 8 and the second air duct 20 always move synchronously and in opposite directions during the adjustment process. This makes the airflow impact force on the upper and lower surfaces of the glass more uniform, which helps to reduce the uneven stress during the tempering process and improve the quality of glass tempering. The diameters of gear 16 and gear 17 can be selected and replaced according to the curvature and thickness of the curved glass to be processed, so that the multiple second air ducts 20 on the second linkage frame 21 can decelerate or accelerate relative to the multiple first air ducts 8 on the first linkage frame 12. By replacing gear 16 and gear 17 with different diameters, the transmission ratio between the first linkage frame 12 and the second linkage frame 21 can be changed, thereby adjusting the movement speed of the second air duct 20 relative to the first air duct 8. When the second air duct 20 decelerates or accelerates, the airflow impact intensity and time on the upper and lower surfaces of the glass at different cooling stages can be adjusted, thereby optimizing the cooling curve of the glass and improving the tempering stress distribution. This structure does not require an additional drive source or complex control system. The proportional adjustment of the movement speed can be achieved simply by changing the gear diameter. The structure is simple, reliable, and low in cost. When the system controls hydraulic cylinder 10 to extend, it simultaneously controls hydraulic cylinder 23 to extend synchronously. During the movement, one end of hydraulic cylinder 23 rotates around adapter 4 and the other end rotates around adapter 3. The thrust is transmitted to the connected linkage 21 through adapter 3. The rated hydraulic strength of hydraulic cylinder 23 is less than that of hydraulic cylinder 10. This reflects the differentiated configuration where linkage 12 needs to bear a larger load and linkage 21 can meet the synchronous movement requirements with a smaller driving force, thus realizing the coordinated adjustment of the upper and lower windshields. The system controls the first hydraulic cylinder 10 to extend, which drives the first linkage frame 12 and the multiple first air ducts 8 connected to it to rise synchronously until the air inlet 25 on each first air duct 8 is fully exposed above the first air box 7. At this time, under the linkage of the transmission mechanism, the corresponding multiple second air ducts 20 descend synchronously, so that their air inlet 25 is fully exposed below the second air box 19. The upward movement of the first air duct 8 and the downward movement of the second air duct 20 are synchronized to ensure that the upper and lower air inlets 25 open at the same time, so that the upper and lower surfaces of the glass can be impacted by the cooling airflow at the same time, avoiding uneven cooling caused by asynchronous opening. At the same time, by blocking the air inlet 25, individual air ducts can be closed to save low-temperature gas for cooling. During the movement of the first linkage frame 12 and the second linkage frame 21, the linkage shafts 36 at their ends slide within the corresponding two linkage ports 30 on the same linkage plate 29. The two linkage shafts 36 together drive the linkage plate 29 to move, thereby causing the directional shaft 31 connected to the linkage plate 29 to slide within the directional sleeve 32. This ensures the synchronicity and consistency of the movement of the two linkage shafts 36. By connecting the two linkage shafts 36 through the same linkage plate 29 and with the guidance of the directional shaft 31 and the directional sleeve 32, it is ensured that the first linkage frame 12 and the second linkage frame 21 remain synchronized during the movement, avoiding jamming or transmission failure caused by asynchronous movement. The linkage plate 29, as an intermediate force transmission component, couples the movement of the two linkage shafts 36 together. With the help of the directional guide structure, the entire transmission process is smoother, reducing vibration and impact, which is beneficial to improving the reliability and service life of the equipment. During the process of the linkage plate 29 driving the directional shaft 31 to slide within the directional sleeve 32, the system controls the third hydraulic cylinder 34 to perform an extension movement. Under the pushing action of the third hydraulic cylinder 34, the two linkage shafts 36 always remain in contact with the inner sidewall of the corresponding linkage port 30, thereby further improving the synchronicity of the movement of the two linkage shafts 36. Through the continuous thrust of the third hydraulic cylinder 34, the two linkage shafts 36 are kept in close contact with the inner sidewall of the linkage port 30, effectively eliminating the transmission gap caused by machining or assembly errors, avoiding idle stroke and impact during the movement. The thrust of the third hydraulic cylinder 34 can be adjusted according to the actual working conditions, and can adaptively compensate for the changes in the fit clearance caused by wear or temperature changes, extending the service life of the equipment while maintaining long-term stable synchronization performance.
