Description

Technical Field

[0001] This application relates to the field of equipment for the production and processing of curved glass, and in particular to a tempering and cooling device for curved glass. Background Technology

[0002] Tempered glass is a type of prestressed glass with advantages such as high strength, good thermal stability, and safety, making it widely used in high-rise building windows and doors, automotive glass, and photovoltaic glass. Besides being processed into flat tempered glass, tempered glass can also be processed into curved tempered glass to meet usage requirements and aesthetic needs. Curved tempered glass is further classified into single-curved tempered glass and multi-curved tempered glass based on the number of curves.

[0003] In actual production, the manufacturing and processing of curved tempered glass is quite difficult, and the product quality is relatively low. The main reason is that after the variable-curvature roller conveyor bends the hot glass into a curved surface with a specific curvature, the air-cooling process of the cooling mechanism often cannot keep up with the undulations of the upper and lower surfaces of the curved glass. Specifically, the distance from which the cooling airflow blown by the upper and lower air grates reaches the surface of the curved glass is inconsistent, resulting in uneven and inconsistent cooling and tempering of the curved glass surface. This easily leads to appearance defects such as stress marks. In particular, when multi-curved glass requires a high degree of curvature in its bending surface, the cooling mechanisms in existing equipment cannot meet the requirements for uniform air-cooling tempering.

[0004] Regarding the aforementioned technologies, the applicant believes that during the tempering process of curved glass, it is difficult to achieve uniform cooling and tempering on each curved surface of the glass, which fails to meet the production quality requirements of curved tempered glass. Summary of the Invention

[0005] In order to ensure that the upper and lower surfaces of each curved surface in curved glass are simultaneously and uniformly cooled by airflow, thereby overcoming appearance quality defects such as stress marks, this application provides a tempering and cooling device for curved glass.

[0006] This application provides a tempering and cooling device for curved glass, which adopts the following technical solution:

[0007] A tempering and cooling device for curved glass includes a support frame, a bending mechanism for bending the glass, and a cooling mechanism, both of which are mounted on the support frame. The bending mechanism includes multiple bending rollers for carrying the glass, all of which are arranged along the glass conveying direction and are elastic.

[0008] The cooling mechanism includes an upper cooling mechanism and a lower cooling mechanism; the upper cooling mechanism includes an upper air grating group composed of multiple upper air grates, a bending component for bending the upper air grating group, and a lifting component for adjusting the height of the upper air grating group, wherein the bending component and the lifting component are both disposed on the support frame; it also includes a first adjustment component for adjusting the bending state of a single upper air grating;

[0009] The lower cooling mechanism includes a lower air grating group composed of multiple lower air grates, the lower air grating group being disposed on the arc-changing mechanism, and each of the lower air grates being located between adjacent arc-changing roller conveyors; it also includes a second adjustment component for jointly adjusting the height of the lower air grates and the arc-changing roller conveyors, and a third adjustment component for adjusting the position of adjacent lower air grates relative to the arc-changing roller conveyors.

[0010] By employing the above technical solution, a variable arc mechanism is used to bend the hot glass, and then upper and lower cooling mechanisms are used simultaneously to air-cool and temper the upper and lower surfaces of the hot glass. By incorporating multiple cooperating adjustment components in the cooling mechanism, the cooling mechanism can match the glass surface formed by the variable arc mechanism, thus creating cooling surfaces with the same shape or similar height. This ensures that during the cold swing motion, the air pressure exerted by the upper and lower cooling mechanisms on each surface of the curved hot glass remains essentially the same at any transport position, further improving the tempering quality of the curved glass.

[0011] For the upper cooling mechanism, the upper air grid assembly is first initially bent by the bending component to match the initial bending shape of the hot glass by the arc-changing mechanism (main curve state: forward bend / reverse bend); the individual upper air grids are then bent a second time by the first adjustment component to match the secondary bending shape of the hot glass by the arc-changing mechanism (secondary curve state: S-shaped bend, spherical bend, other irregular bends, etc.); and the air blowing distance between the upper air grid assembly and the hot glass is adjusted by the lifting component, thereby directly affecting the air cooling process of the upper surface of the glass.

[0012] For the lower cooling mechanism, since the lower air grid assembly undergoes initial bending synchronously with the bending of the curve-changing mechanism, the second adjustment component performs a secondary bending of each lower air grid to match the secondary bending shape of the hot glass by the curve-changing mechanism. Furthermore, the third adjustment component can perform a secondary fine adjustment of the position between the lower air grid and the curve-changing roller conveyor, further refining the air cooling effect achievable by the cooling mechanism to meet the processing requirements of curved tempered glass of different sizes (especially Low-E glass).

[0013] By synchronously bending the upper and lower cooling mechanisms in real time, the cooling airflow blown to the upper and lower surfaces of the curved glass remains uniform, resulting in a relatively consistent contraction speed of each part of the glass during the cold bending process. This reduces the occurrence of ripples or uneven thickness on the glass surface that may be caused by uneven cooling, thereby maintaining the flatness and curvature accuracy of the glass surface. Furthermore, it makes the internal stress distribution of the curved glass uniform, reduces the generation of residual stress, and thus improves the tempering quality and impact resistance of the curved glass.

[0014] Preferably, the upper air grille includes multiple interconnected upper air blowing boxes, and a flexible hose is provided between adjacent upper air blowing boxes; the lower air grille includes multiple interconnected lower air blowing boxes, and adjacent lower air blowing boxes are also connected by the flexible hose.

[0015] The air blowing sections of the upper and lower air blowing boxes face the variable arc roller conveyor, and each upper and lower air blowing box is connected to an air collecting box on the side away from the air blowing section. Safety wheels are also provided between adjacent upper air blowing boxes.

[0016] By adopting the above technical solution, flexible hoses are used to connect the upper and lower air boxes to form a flexible and interconnected upper and lower air grid. On the one hand, this allows for bending of the shape in conjunction with various adjustment components, thus ensuring the air-cooling tempering effect of the upper and lower air grids. On the other hand, this arrangement results in more uniform and controllable cooling airflow to the upper and lower surfaces of the glass. Simultaneously, the safety wheels installed between the upper air boxes create a "safe transition surface" of the same shape or height near the upper surface of the curved glass, preventing scratches caused by hard contact between the upper surface of the glass and the upper cooling mechanism during the curved glass's cold swinging motion, further reducing the defect rate of curved glass production.

[0017] Preferably, the second adjustment component includes a plurality of first synchronization rods arranged along the length direction of the variable arc roller conveyor, and the first synchronization rods are also elastic. A single variable arc roller conveyor and a single first synchronization rod are connected by a third adjustment component. A plurality of third adjustment components are provided and arranged at intervals along the length direction of the first synchronization rods.

[0018] Furthermore, each of the individual variable arc roller conveyors and the adjacent lower air grating are also connected via the third adjustment assembly.

[0019] By adopting the above technical solution, a first synchronous rod is set along the same length direction below a single curved roller conveyor. The first synchronous rod is also elastic. The two are connected to each other by a third adjustment component to form a synchronous bending relationship between the curved roller conveyor and the first synchronous rod. By directly acting on the first synchronous rod, the synchronous bending of the curved roller conveyor is indirectly affected. This can greatly alleviate the force acting on the curved roller conveyor, making the bending state of the curved roller conveyor smoother and more natural, thereby ensuring the appearance quality of the multi-curved glass.

[0020] The third adjustment component establishes a connection between the variable-arc roller conveyor and the adjacent lower air grating. This ensures that when the variable-arc roller conveyor bends, the bending action is simultaneously transmitted to the adjacent, flexible lower air grating. This allows the lower cooling mechanism to form a cooling surface that matches the variable-arc mechanism, thus guaranteeing the tempering and cooling effect of the device. In fact, the third adjustment component establishes a synchronous bending relationship between the variable-arc roller conveyor, the first synchronizing rod, and the adjacent lower air grating, exhibiting high integration and improving the bending stability of the device.

[0021] Preferably, the second adjustment component further includes a plurality of height adjustment members, which are connected to the third adjustment component;

[0022] The height adjustment component includes a screw, a screw sleeve, and a drive component. The screw sleeve is threaded onto the screw, and the drive component is installed at the end of the screw away from the screw sleeve. Each drive component is mounted on the support frame.

[0023] By adopting the above technical solution, the height adjustment component is set as a mechanical linkage structure consisting of a screw, a sleeve, and a drive component. It can achieve linear motion in the height direction through the rotational movement of the screw, thereby achieving high transmission efficiency and high precision in adjusting the height of the connection point (third adjustment component) on the first synchronous rod. Simultaneously, the height adjustment component is compact and occupies little space. Multiple sets can be integrated simultaneously within the limited space below the variable-arc roller conveyor to achieve complex motion control, forming a complete height adjustment roller surface. This synchronously completes the curvature formation and adjustment of the roller surface, further ensuring that the hot glass is in a "floating" bearing state during the cold swing motion. This allows the variable-arc roller conveyor to always conform to the curved bottom surface of the hot glass without large-scale undulations, making the cold swing motion more stable and controllable, and reducing the probability of shape defects and other problems.

[0024] Preferably, the lower air blowing box includes a first lower air blowing box and a second lower air blowing box, the first lower air blowing box being connected to the air collecting box, and the second lower air blowing box being connected to the screw sleeve through the third adjusting component.

[0025] By adopting the above technical solution, the lower air box is further rationally divided into a first lower air box and a second lower air box, and the two are arranged in a certain regular pattern (such as single-interval arrangement). On the one hand, since the lower air boxes are interconnected by flexible hoses, the first lower air box, which is arranged at intervals, can reduce the number of ventilation ducts between the air collection box and the lower air grid group, thereby reducing the production cost of the device. On the other hand, by establishing an indirect connection between the second lower air box, which is arranged at intervals, and the height adjustment component, the number of height adjustment components can be reduced without affecting the free bending of the variable arc roller / first synchronous rod. This can also reduce the production cost of the device and avoid the inconvenience of maintenance difficulties caused by too many mechanical parts under the variable arc roller surface (composed of multiple variable arc rollers).

[0026] Preferably, the third adjustment component includes a first mounting plate, a second mounting plate, and a limiting member. Multiple limiting members are provided and slidably inserted between the first mounting plate and the second mounting plate. The sliding direction of the limiting member is set along the adjustment direction of the height adjustment member.

[0027] A single first synchronizing rod passes through multiple first mounting plates, and the side of the first mounting plate opposite to the threaded sleeve is fixedly connected to the variable arc roller conveyor.

[0028] The second mounting plate is fixedly connected to the adjacent lower air box, and the screw sleeve passes through the second mounting plate and is fixedly connected to the first mounting plate.

[0029] By adopting the above technical solution, the third adjustment component is configured as a mechanically linked structure consisting of a first mounting plate, a second mounting plate, and a limiting member. By sliding the limiting member, the positional relationship between the first and second mounting plates is changed, thereby indirectly altering the height of adjacent lower air-blowing boxes and the intermediate curved roller conveyor. This allows for secondary micro-adjustment of the lower air grid assembly, further meeting the production and processing requirements of related special curved glass. Especially for Low-E glass (and other coated glass), by changing the distance between the air-blowing section of the lower air-blowing box and the lower surface of the hot glass carried by the curved roller conveyor, the air-cooling state of the hot glass can be more precisely adjusted to prevent deformation and warping.

[0030] Preferably, the bending assembly includes a plurality of second synchronous rods arranged along the length direction of the variable arc roller conveyor, and an arc-lifting assembly for lifting the second synchronous rods. Each second synchronous rod has a bending chain plate at both ends, and adjacent second synchronous rods are connected to each other along the glass conveying direction and bend through the bending chain plate.

[0031] The second synchronizing rod is disposed between adjacent upper air grilles, and multiple safety wheels are spaced apart on the second synchronizing rod. The safety wheels protrude between adjacent upper air boxes, and the rotation axis of the safety wheels is perpendicular to the glass conveying direction.

[0032] By employing the above technical solution, using an arc-lifting assembly, a variable-arc chain plate, and second synchronous rods, the upper air grid assembly loaded by multiple second synchronous rods arranged along the glass conveying direction is lifted, achieving the initial bending of the upper cooling mechanism to match the main curved shape of the curved hot glass. Simultaneously, multiple sets of safety wheels are installed on the second synchronous rods, and the rotation direction of the safety wheels is aligned with the conveying direction of the hot glass to prevent contact between the upper mechanical components and the hot glass, thus avoiding impact on the glass processing quality.

[0033] Preferably, the second synchronizing rod is also elastic;

[0034] The first adjustment component also includes multiple height adjustment components, which are spaced apart from the second synchronizing rod, and the screw sleeve is fixedly connected to the second synchronizing rod; the height adjustment direction of the height adjustment component relative to the second synchronizing rod is opposite to the height adjustment direction of the height adjustment component relative to the first synchronizing rod.

[0035] By employing the above technical solution, multiple height adjustment components are used to bend and adjust a single second synchronous rod in the same manner, achieving secondary bending of the upper cooling mechanism to match the secondary curvature shape of the curved hot glass. Furthermore, the direction of action of the height adjustment components on the second synchronous rod is opposite to that of the height adjustment components on the first synchronous rod, causing the upper and lower air grating groups to undergo bending changes that match the variable arc roller conveyor. This, in turn, causes the blowing action of the upper and lower cooling mechanisms to "clamp" the upper and lower surfaces of the hot glass, further maintaining good air-cooled tempering quality.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. This application can keep the cooling airflow blown to the upper and lower surfaces of the curved glass uniform through real-time synchronous bending of the upper and lower cooling mechanisms. This results in relatively consistent shrinkage speed of each part of the glass during the cold bending process, thereby reducing the occurrence of ripples or local thickness inconsistencies on the glass surface that may be caused by uneven cooling. This maintains the flatness and curvature accuracy of the glass surface, and further makes the internal stress distribution of the curved glass uniform, reducing the generation of residual stress, thereby improving the tempering quality and impact resistance of the curved glass.

[0038] 2. This application uses flexible hoses to connect the upper and lower air boxes, forming a flexible and interconnected upper and lower air grid. On the one hand, this allows for bending of the shape in conjunction with various adjustment components, ensuring the air-cooling tempering effect of the upper and lower air grids. On the other hand, this arrangement results in more uniform and controllable cooling airflow to the upper and lower surfaces of the glass. Simultaneously, the safety wheels between the upper air boxes create a "safe transition surface" of the same shape or similar height near the upper surface of the curved glass, preventing scratches caused by hard contact between the upper surface of the glass and the upper cooling mechanism during the curved glass's cold swinging motion, further reducing the defect rate in the production of curved glass.

[0039] 3. This application sets the third adjustment component as a mechanically linked structure consisting of a first mounting plate, a second mounting plate, and a limiting member. By sliding the limiting member, the positional relationship between the first and second mounting plates is changed, thereby indirectly altering the height of adjacent lower air blowing boxes and the intermediate curved roller conveyor. This enables secondary micro-adjustment of the lower air grid assembly, further meeting the production and processing requirements of related special curved glass. Especially for Low-E glass (and other coated glass), by changing the distance between the air blowing section of the lower air blowing box and the lower surface of the hot glass carried by the curved roller conveyor, the air cooling state of the hot glass can be more precisely adjusted to prevent deformation and warping.

[0054] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0055] This application discloses a tempering and cooling device for curved glass, referring to... Figure 1 and Figure 2 It includes a support frame 1, an arc-changing mechanism 2, and a cooling mechanism 3. The support frame 1 can be a conventional frame frame structure to support the arc-changing mechanism 2 and the cooling mechanism 3. The specific frame structure is not limited. This embodiment adopts a cubic frame structure.

[0056] The arc-changing mechanism 2 includes multiple arc-changing roller conveyors 21 arranged at equal intervals. The length direction of each arc-changing roller conveyor 21 is arranged along the width direction of the support frame 1, and multiple transmission wheels can be installed at equal intervals along the length direction of each arc-changing roller conveyor 21. The transmission wheels are fixedly sleeved on the roller body of the arc-changing roller conveyor 21, and the rotation axis of the transmission wheels is perpendicular to the glass conveying direction. Arc-changing chain plates 22 are rotatably connected to both ends of each arc-changing roller conveyor 21 along its own length direction. The arc-changing chain plates 22 can be any of T-shaped plates, T-shaped plates, trapezoidal plates, or triangular plates. In this embodiment, a T-shaped plate composed of crossbars and longitudinal bars is selected. The crossbars of adjacent arc-changing chain plates 22 are hinged to each other, thereby indirectly connecting multiple arc-changing roller conveyors 21 in series to form an arc-changing roller surface with the conveying direction along the length direction of the support frame 1. When multiple variable arc roller conveyors 21 maintain the same horizontal height, the entire variable arc roller surface is horizontal. Through the drive control mechanism (not shown in the figure) installed on the carrier frame 1, and the transmission components that connect each variable arc roller conveyor 21 in series, the drive is started to drive the variable arc roller conveyor 21 to rotate stably, thereby carrying the hot glass heated in the previous process on the upper surface of the variable arc roller surface for cold swinging motion. That is, the transmission direction of the hot glass is set along the length direction of the carrier frame 1.

[0057] Meanwhile, the arc-changing chain plates 22 at both ends of the arc-changing roller track 21 located in the middle of the arc-changing roller surface are fixedly connected to the crossbeams extending from the support frame 1, while the arc-changing roller tracks 21 at other positions are in a free-adjusting state, that is, they are not connected to the support frame 1. The support frame 1 is also equipped with an arc-lifting assembly 23, which includes a drive motor, a transmission cable, and fixed pulleys. The transmission cable can be set into multiple sets according to the lifting effect. The transmission cable is sleeved on a fixed pulley group composed of multiple fixed pulleys, and the arc-changing chain plates 22 on the two sets of arc-changing roller tracks 21 at both ends of the glass conveying direction are fixedly connected at the end of the transmission cable. The drive motor drives the fixed pulley group to rotate so as to drive the transmission cable to synchronously lift the arc-changing roller tracks 21 at both ends, so as to slowly form a specific curvature of the entire arc-changing roller surface, thereby realizing the positive bending processing of hot glass. When hot glass needs to be processed into a reverse-bending shape, the lifting effect of the drive motor on the transmission cable needs to be reduced. The self-weight of the variable-arc roller surface is used to make the variable-arc roller tracks 21 at both ends slowly descend downwards, while the middle variable-arc roller track 21 forms a fulcrum (arc high point) due to its load-bearing connection with the bearing frame 1, so as to slowly form a specific curvature of the entire variable-arc roller surface, thereby realizing the reverse bending processing of hot glass.

[0058] Reference Figures 1 to 3 The cooling mechanism 3 includes an upper cooling mechanism 31 for air-cooling tempering the upper surface of the hot glass and a lower cooling mechanism 32 for air-cooling tempering the lower surface of the hot glass. The upper cooling mechanism 31 is located above the curve-changing roller surface and includes an upper air grate group 311 composed of multiple upper air grate groups 311. The length direction of each upper air grate is along the length direction of the curve-changing roller track 21, and the upper air grates are arranged at equal intervals. Each upper air grate is composed of multiple interconnected upper air blowing boxes 3111. A flexible hose 36 is fixedly installed between adjacent upper air blowing boxes 3111, and the upper air grate is formed by connecting the upper air blowing boxes 3111 through the hoses 36 to achieve flexibility. In this embodiment, the flexible hose 36 is specifically selected as a corrugated pipe. The side of the upper air blowing box 3111 facing the curve-changing roller surface has an air blowing section, which consists of multiple evenly spaced air outlets. The side of the upper air blowing box 3111 facing away from the curve-changing roller surface is connected to an air collection box (not shown in the figure) through an air supply pipe (not shown in the figure). The air collection box should be able to provide a stable and controllable air source to each air blower box 3111 in the upper air grid group 311 through the air supply duct.

[0059] The upper cooling mechanism 31 also includes a bending component 312 for bending the upper air grating group 311. Since the upper air grating group 311 needs to be bent into the same bending state as the arc-changing mechanism 2 acting on the arc-changing roller conveyor 21 through the bending component 312, the bending component 312 of the upper cooling mechanism 31 and the arc-changing mechanism 2 of the device are implemented using the same or similar mechanical structures. Specifically, the bending component 312 includes a plurality of second synchronous rods 331 arranged at equal intervals. The length direction of the second synchronous rods 331 is consistent with the length direction of the upper air grating, and a single second synchronous rod 331 is located between two adjacent groups of upper air gratings. Bending chain plates 332 are installed at both ends of the second synchronous rods 331, and the single second synchronous rod 331 and the two adjacent groups of upper air gratings are integrated into the same upper cooling unit through two bending chain plates 332 in the same group. In this embodiment, the specific structure and connection method of the bending chain plate 332 are the same as those of the arc-changing chain plate 22 in the arc-changing mechanism 2. That is, the bending chain plate 332 is selected as a T-shaped plate composed of crossbars and longitudinal bars, and the crossbars of adjacent bending chain plates 332 are hinged to each other, thereby indirectly connecting multiple upper cooling units in series to form a whole. The bending assembly 312 also includes the same arc-lifting assembly 23 as in the arc-changing mechanism 2. It also uses a similar structure of drive motor, transmission cable and fixed pulley to lift the two sets of upper cooling units at both ends along the glass conveying direction, thereby forming the upper air grid assembly 311 into a positive or negative bend with the same as the arc-changing roller surface. Meanwhile, multiple safety wheels 3112 are also equidistantly installed on each of the single second synchronizing rods 331. Each safety wheel 3112 protrudes from the adjacent upper air blowing box 3111. That is, when the entire upper air grid assembly 311 is kept horizontal, the lowest part of the safety wheel 3112 is lower than the lowest part of the upper air blowing box 3111 on both sides. This ensures that when the hot glass is in a cooling swing motion, if the upper surface of the glass comes into contact with the upper cooling mechanism 31, it will preferentially contact the safety wheel 3112 rather than other mechanical parts. Furthermore, the rotation axis of the safety wheel 3112 is perpendicular to the glass conveying direction.

[0060] The upper cooling mechanism 31 also includes a lifting assembly 313 for adjusting the height of the upper air grille assembly 311. The lifting assembly 313 may include a lifting motor and a pulley system. By mounting the upper air grille assembly 311 onto a specific frame structure, and then connecting the frame structure to the support frame 1 via the pulley system, the sliding direction (lifting direction) is set along the height direction of the support frame 1. The lifting motor serves as the power source for automated drive, allowing the lifting assembly 313 to adjust the height of the entire upper air grille assembly 311. This changes the airflow distance between the upper air grille assembly 311 and the upper surface of the hot glass, thus affecting the tempering quality. It should be understood that the lifting assembly 313, as an auxiliary structure, does not necessarily affect the air-cooled tempering process of the upper cooling mechanism 31, but rather allows it to meet more processing conditions. Furthermore, a limiting structure can be added to restrict its lifting limit to prevent the upper air grille assembly 311 from slipping.

[0061] The upper cooling mechanism 31 also includes a first adjustment component 33 for adjusting the bending state of a single upper air grille. The first adjustment component 33 includes multiple height adjustment elements 37, which are equidistantly installed above the second synchronous rod 331 and extend along the length direction of the second synchronous rod 331. The number of first adjustment components 33 is the same as the number of second synchronous rods 331, and the second synchronous rod 331 is elastic. In this embodiment, the second synchronous rod 331 is selected as a spring steel wire. The height adjustment element 37 includes a screw 371, a screw sleeve 372, and a drive element 373. The screw sleeve 372 is threaded onto the body of the screw 371, and the top of the screw sleeve 372 is fixedly installed on the second synchronous rod 331. The length directions of both the screw 371 and the screw sleeve 372 are arranged along the height direction of the support frame 1 and perpendicular to the length direction of the second synchronous rod 331. The drive component 373 is installed at the end of the screw 371 away from the sleeve 372 and is fixedly installed on the frame structure extending from the lifting assembly 313. It can drive the screw 371 to drive the sleeve 372 to move forward or retract in the vertical direction, thereby causing the second synchronous rod 331 to bend to cooperate with the secondary bending that occurs synchronously on the variable arc roller conveyor 21 (the secondary curvature state of the hot glass), so that the upper air grid assembly 311 synchronously forms the blowing curved surface. For a single second synchronous rod 331, the specific number of height adjustment components 37 is usually 5-11, and is adjusted according to the processing requirements of multi-curved glass.

[0062] Reference Figure 2 and Figure 3The lower cooling mechanism 32 is located below the curved roller surface and includes multiple lower air grating groups 321. The length of each lower air grating is along the length of the curved roller conveyor 21, and the lower air gratings are arranged at equal intervals. The arrangement of the lower air gratings requires that each lower air grating be installed between adjacent curved roller conveyors 21 to reduce the obstruction of airflow from the rollers, thereby ensuring that the hot glass can receive uniform and stable airflow from the gaps between adjacent curved roller conveyors 21 during reciprocating motion. Each lower air grating is composed of multiple interconnected lower air boxes 3211. Adjacent lower air boxes 3211 are also fixedly installed via flexible hoses 36. The lower air grating is formed by connecting the lower air boxes 3211 with the flexible hoses 36, thus providing flexibility. In this embodiment, the flexible hoses 36 are also corrugated pipes. The side of the lower air box 3211 facing the arc-changing roller surface is also provided with an air blowing section (with the same structure); the side of the lower air box 3211 away from the arc-changing roller surface is connected to the air collection box through an air supply pipe.

[0063] The lower cooling mechanism 32 also includes a second adjustment component 34 for jointly adjusting the height of the lower air grating and the variable arc roller conveyor 21. The second adjustment component 34 includes multiple first synchronization rods 341 arranged at equal intervals. The length direction of the first synchronization rods 341 is consistent with the length direction of the lower air grating, and the first synchronization rods 341 are located directly below the variable arc roller conveyor 21. The number of first synchronization rods 341 and the number of variable arc roller conveyors 21 are the same, and they are arranged in a one-to-one correspondence. The first synchronization rods 341 are located between adjacent lower air gratings, and a single first synchronization rod 341 is integrated with two adjacent sets of lower air gratings into the same lower cooling unit through mechanical components (such as the connection structure of clamps and bases). The first synchronization rods 341 are also elastic. In this embodiment, the first synchronization rods 341 are also made of spring steel wire, and a single set of first synchronization rods 341 and the variable arc roller conveyor 21 are synchronously connected through multiple sets of mechanical mounting components, so that the two can synchronously transmit bending changes. The second adjustment assembly 34 also includes multiple height adjustment components 37 with identical structures. These height adjustment components 37 are equidistantly installed below the first synchronizing rod 341 and extend along the length of the first synchronizing rod 341. The top of the threaded sleeve 372 is fixedly installed on the first synchronizing rod 341 and its mechanical mounting components. The length directions of the screw 371 and the threaded sleeve 372 are also along the height direction of the support frame 1 and perpendicular to the length direction of the first synchronizing rod 341. The driving component 373 is installed at the end of the screw 371 away from the threaded sleeve 372 and fixedly installed on the extended beam structure of the support frame 1. It can drive the screw 371 to move the threaded sleeve 372 in a vertical direction, either pushing or retracting it. This causes the first synchronizing rod 341 and the variable-arc roller conveyor 21 to undergo secondary bending, indirectly causing the upper air grating assembly 311 to synchronously form a blowing curved surface. For a single first synchronizing rod 341, the specific number of height adjustment components 37 is typically 5-11, and is adjusted according to the processing requirements of the multi-curved glass.

[0064] Reference Figure 6 and Figure 7The lower cooling mechanism 32 also includes a third adjustment component 35 for adjusting the position of adjacent lower air grilles relative to the variable arc roller conveyor 21. The third adjustment component 35 includes a first mounting plate 351, a second mounting plate 352, and a limiting member 353. Multiple third adjustment components 35 are provided, serving as the aforementioned mechanical mounting parts to construct the lower cooling unit between a single first synchronizing rod 341 and two adjacent sets of lower air grilles. Specifically, the first mounting plate 351 is a rectangular plate with holes along its width for the first synchronizing rod 341 to pass through, located in the middle. The upper surface of the first mounting plate 351 is fixedly connected to the variable arc roller conveyor 21, and the lower surface of the first mounting plate 351 is fixedly connected to the top of the threaded sleeve 372 of the height adjusting member 37. Connecting structures extend from the four apex corners of the first mounting plate 351. In this embodiment, the connecting structure is a crescent-shaped groove, and the groove direction is along the width direction of the first mounting plate 351. The second mounting plate 352 is a frame structure composed of two long horizontal sheets and two short vertical sheets. A rectangular through-hole formed by a strip-shaped sheet in the middle of the second mounting plate 352 allows the threaded sleeve 372 of the height adjustment component 37 to pass through and be fixedly connected to the lower surface of the first mounting plate 351. The two ends extending from the long horizontal sheets of the second mounting plate 352 respectively support two adjacent lower air blowing boxes 3211, and are connected to the bottom of the two adjacent lower air blowing boxes 3211 by detachable structures such as bolts. Four limiting members 353 are provided, located at the four delayed structures corresponding to the first mounting plate 351 and the second mounting plate 352. The limiting members 353 are rod-shaped structures with long, narrow grooves along their length. Bolts are threaded through the limiting members 353 along their length to establish a detachable connection, and the length of the limiting members 353 is aligned with the length of the threaded sleeve 372 of the screw 371.

[0065] Reference Figure 4 and Figure 5The third adjustment component 35 enables the single variable-arc roller conveyor 21 to have two different installation states with the two adjacent sets of lower air grids. Installation state 1 is a state with a shorter air blowing distance, specifically, bolts are sequentially inserted into the limiting member 353, the first mounting plate 351, and the second mounting plate 352 to form a detachable connection; installation state 2 is a state with a longer air blowing distance, specifically, bolts are sequentially inserted into the first mounting plate 351, the limiting member 353, and the second mounting plate 352 to form a detachable connection. The air blowing distance adjusted by the above two installation states is actually the length of the limiting member 353, so different lengths of the limiting member 353 can be selected according to different special glass processing requirements. The actual adjustment operation is to loosen the bolts in each limiting member 353 by rotating them, and rotate the limiting member 353 so that the side with the long groove faces the downward air blowing box 3211. This allows the limiting member 353 to slide through the crescent groove of the first mounting plate 351 and place it between the first mounting plate 351 and the second mounting plate 352 (i.e., change from installation state 1 to installation state 2). Then, rotate the limiting member 353 in the opposite direction and tighten the bolts to build a stable installation state.

[0066] Reference Figure 3 Each lower air blowing box 3211 further includes a first lower air blowing box 3212 and a second lower air blowing box 3213. The first lower air blowing box 3212 is connected to the air collecting box through an air supply pipe, while the second air blowing box is connected to the end of the height adjusting member 37 away from the drive member 373 through a third adjusting component 35. Since the lower air blowing boxes 3211 are connected to each other, there are multiple ways to arrange the first lower air blowing box 3212 and the second lower air blowing box 3213 without affecting the cooling effect of the lower air grid or the secondary bending of the height adjusting member 37 on the variable arc roller 21. The first lower air blowing box 3212 and the second lower air blowing box 3213 can be arranged in an alternating manner, or two first lower air blowing boxes 3212 can be installed continuously and then one second lower air blowing box 3213 can be installed at an interval.

[0067] The implementation principle of a copper ring processing device according to an embodiment of this application is as follows: hot glass is conveyed to the arc-changing roller conveyor 21, and the arc-changing mechanism 2 is activated to bend the hot glass to obtain curved hot glass; the lifting component 313 is activated to perform preliminary height adjustment of the upper air grid group 311, and then the bending component 312 performs preliminary bending of the upper air grid group 311 to conform to the main curvature state of the curved hot glass; then the first adjustment component 33 corresponding to different upper air grids is activated to perform secondary bending to conform to the secondary curvature state of the curved hot glass; and the lower air grid group 321 is bent by the arc-changing mechanism 2 to form a shape conforming to the curved hot glass. In the main curved state, the second adjustment component 34 corresponding to the adjacent lower air grille is activated to perform a secondary bending to conform to the secondary curved state of the curved hot glass. Then, air is supplied to the upper air grille group 311 and the lower air grille group 321 through the air collection box to perform air-cooled tempering on both the upper and lower surfaces of the hot glass. The hot glass is carried by the variable arc roller conveyor 21 to perform cold swinging motion. The upper air grille group 311 is adjusted by the first adjustment component 33 and the lower air grille group 321 is adjusted by the second adjustment component 34 to realize the variable arc mechanism 2 and the cooling mechanism 3 bending synchronously with the movement of the curved hot glass until the curved hot glass is tempered and formed.

[0068] For special curved glass with specific processing requirements, the third adjustment component 35 can be used to adjust the single variable arc roller 21 and the two adjacent lower air grids between installation state 1 and installation state 2 before the above operations. This allows for secondary fine adjustment of the air blowing distance of the lower air grid group 321 on the lower surface of the curved hot glass, thereby obtaining different air-cooling tempering effects and effectively solving problems such as deformation and warping of the coated glass. Furthermore, the above processing steps, combined with the device drive control mechanism, can achieve programmed precision control, reduce manual input in the process, and realize highly automated and intelligent production processing. After the multi-curved hot glass is initially formed by the arc-changing mechanism 2, as the arc-changing roller surface reciprocates under load, the upper air grid group 311 also bends into a curved surface matching the arc-changing roller surface under the interference of the first adjustment component 33 and the lifting component 313. Similarly, the lower air grid group 321 also bends into a curved surface matching the arc-changing roller surface under the interference of the second adjustment component 34 and the third adjustment component 35. This ensures that the air volume, air pressure, and other indicators of the cooling airflow blown from the cooling mechanism 3 to each curved surface of the multi-curved hot glass during the cold swing motion remain the same or within a reasonable range, further solving the problem of appearance defects such as stress spots. It is worth noting that when the hot glass undergoes cold swing motion, not only does the arc-changing roller surface achieve "floating" load change, but the upper and lower air grids also bend synchronously at all times, and this bending change is transmitted back and forth with the hot glass in between.

[0069] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
