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 forming apparatus 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. For example, Chinese patent CN216191886U discloses a lifting device using flexible limit control. When processing single-curved tempered glass, the hot glass is typically conveyed to a variable-curvature roller surface composed of multiple variable-curvature rollers. Each variable-curvature roller has interconnected arc-forming chain plates installed at both ends. The lifting assembly connects the arc-forming chain plates on both sides for lifting, thus bending the hot glass to the required curvature. Combined with a cooling mechanism, cold-swinging tempering is performed, and the hot glass oscillates back and forth along the variable-curvature path under the drive of the variable-curvature rollers. However, when producing multi-curved tempered glass, the above-mentioned single-curved tempered glass cannot meet the processing requirements. This results in multiple curved surfaces not being able to maintain constant contact with the variable-curvature roller surface at the same time, making the hot glass prone to uncontrollable deformation during cold-swinging tempering, thus causing shape defects in the multi-curved tempered glass.

[0004] Regarding the aforementioned technologies, the applicant believes that it is crucial to develop a production and processing equipment that can simultaneously produce both single-curved and multi-curved tempered glass, while also ensuring the quality of the multi-curved tempered glass and reducing problems such as shape defects. Summary of the Invention

[0005] In order to simultaneously meet the production needs of single-curved tempered glass and multi-curved tempered glass, and to ensure the quality of the curvature tempering of multi-curved tempered glass, this application provides a tempering and forming apparatus for curved glass.

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

[0007] A tempering and forming apparatus for curved glass includes a support frame, a curve-changing mechanism, and a cooling mechanism, wherein the curve-changing mechanism and the cooling mechanism are both mounted on the support frame; the curve-changing mechanism includes multiple curve-changing roller tracks and a lifting assembly for lifting the curve-changing roller tracks, each of the curve-changing roller tracks has a curve-changing chain plate at both ends, and adjacent curve-changing roller tracks are connected to each other along the glass conveying direction and bend through the curve-changing chain plates;

[0008] The arc-changing mechanism further includes an adjustment component for adjusting the bending state of a single arc-changing roller, and the arc-changing roller is elastic; the adjustment component includes a synchronizing rod arranged along the length direction of the arc-changing roller, and the synchronizing rod is also elastic, and a plurality of first fasteners are spaced apart between the synchronizing rod and the arc-changing roller; the adjustment component also includes a plurality of height adjusting members, and a second fastener is arranged between each height adjusting member and the synchronizing rod, and each second fastener is spaced apart along the length direction of the synchronizing rod.

[0009] By adopting the above technical solution, the hot glass is mainly bent by a variable arc mechanism, and the bent hot glass is then air-cooled and tempered by a cooling mechanism. On the one hand, the variable arc rollers, variable arc chain plates, and lifting components in the variable arc mechanism lift the roller surface formed by multiple variable arc rollers arranged along the glass conveying direction to achieve the initial bending of the hot glass to form the main curved state. At this point, it can meet the processing needs of most single-curved tempered glass on the market.

[0010] On the other hand, when the hot glass is in a curved state, a synchronous bending relationship is maintained between the curved glass and the synchronous rods by using a synchronous rod arranged along the same length below a single curved roller and multiple first fasteners arranged in a row. Multiple height adjustment components are arranged along the length of the single synchronous rod, and a synchronous height change relationship is established between the two by second fasteners. When the height adjustment components cause multiple points on the synchronous rod connected by the second fasteners to change height, this height change is indirectly transmitted to the curved roller, causing the single curved roller to bend and deform at one or more points, presenting a single curve. When multiple curved rollers are bent and deformed, the roller surface they collectively form exhibits a free-form surface, thus achieving secondary or multiple bending of the hot glass to meet the processing requirements of multi-curved tempered glass.

[0011] Preferably, the height adjusting component is rotatably connected to the second fastener. The height adjusting component includes a screw, a screw sleeve, a support base, and a driving component. The screw sleeve and the support base are both threaded onto the screw, and the screw sleeve is fixedly connected to the support base. The driving component is installed at the end of the screw away from the screw sleeve.

[0012] The second fastener includes a hinge seat and a mounting seat. The mounting seat is fixedly connected to the synchronizing rod, and the hinge seat is rotatably connected to the threaded sleeve. The mounting seat has a sliding groove, and the hinge seat is engaged in the sliding groove and slidably connected to the mounting seat. The sliding direction of the hinge seat is consistent with the length direction of the synchronizing rod.

[0013] By adopting the above technical solution, the height adjustment component is set as a mechanical linkage structure consisting of a screw, a screw sleeve, a support base, 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 (second fastener) on the synchronous rod. Simultaneously, the height adjustment component is compact and occupies little space. Multiple sets can be integrated 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.

[0014] The second fastener is configured as a sliding connection structure between the hinge seat and the mounting seat, thus maintaining a relatively sliding connection between the threaded sleeve and the synchronizing rod. Since the threaded sleeve's pushing or retracting motion is vertical, for hot-state glass with different bending requirements, the threaded sleeve, which remains fixed at a specific bending position, will tilt and oscillate under force. The sliding space between the hinge seat and the mounting seat provides relief in the direction perpendicular to the threaded sleeve's pushing motion, thus keeping the screw structure essentially vertical. The screw's tilt angle is balanced by the sliding motion of the hinge seat and the hinge rotation, further maintaining the stable and controllable performance of the height adjustment component when adjusting the height of the synchronizing rod. This also reduces tensile mechanical fatigue of the screw structure, improves the service life of mechanical components, and indirectly ensures the processing quality of curved tempered glass.

[0015] Preferably, at least one of the plurality of second fasteners on the synchronizing rod has no groove on the mounting base, and the hinged seat is fixedly connected to the mounting base.

[0016] By adopting the above technical solution, a fixed point is added when the mounting seat and hinge seat of at least one second fastener on a single synchronous rod are not connected by a sliding connection, meaning that the entire roller can bend and change shape. This fixed point is usually set as the lowest or highest point of the curvature according to the shape requirements of the curved tempered glass. Thus, when the entire curved roller surface undergoes multiple curvatures, there is a support point for positioning and fixing, which can greatly improve the working stability of the curved mechanism. Furthermore, the adjustment component located at this fixed point can also limit the curvature limit of other adjustment components on the same roller track, further improving the arc forming effect of the curved mechanism.

[0017] The location of this fixed point is not limited. When a single fixed point exists and is located in the middle of the arc-changing roller conveyor, curved glass with a positive arc cross-section can be produced. When a single fixed point exists but is located near both ends of the arc-changing roller conveyor, curved glass with an eccentric arc cross-section can be produced. The number of these fixed points is also not limited. However, this application typically does not set all second fasteners to a fixed connection, and the number of second fasteners with sliding connections is significantly greater than the number of second fasteners with fixed connections, in order to achieve a better balance between the arc-changing processing performance and operational stability of the device.

[0018] Preferably, the support frame includes a lower support beam, and each of the driving components is disposed on the lower support beam;

[0019] A lifting assembly is also provided between the driving component and the screw. The lifting assembly includes a bushing, a worm gear, an upper limit member, and a lower limit member. The bushing is sleeved on the screw, and the worm gear is threaded onto the screw. The upper limit member and the lower limit member are both fixedly connected inside the bushing, and the worm gear is located between the upper limit member and the lower limit member along the length direction of the screw. The output end of the driving component passes through the bushing and is connected to the worm gear.

[0020] By adopting the above technical solution, the lifting assembly is configured as a mechanical linkage structure consisting of a bushing, a worm gear, an upper limit component, and a lower limit component. This improves the transmission efficiency and stability of the drive component for the screw. The lifting assembly is fitted onto the screw, fixing the positions of the bushing and the upper and lower limit components. The drive component directly drives the internal worm gear to rotate. Because the worm gear is limited by the upper and lower limit components, it cannot move in height, thus causing a relative change in the height of the screw body. This directly affects the protrusion or retraction of the screw, influencing the degree of bulging or concavity of the synchronous rod and the arc-changing roller conveyor, thereby increasing the bending range (bending limit) of the arc-changing mechanism. Furthermore, as a transmission component, the lifting assembly provides more installation methods between the drive component and the lower support beam, allowing for a suitable and non-interfering installation structure when a large number of adjustment components are required.

[0021] Preferably, the first fastener and the second fastener are arranged at adjacent intervals on the synchronizing rod.

[0022] By adopting the above technical solution, the multiple first fasteners and multiple second fasteners on the synchronizing rod are arranged adjacently and at intervals, which can balance the bending force between the synchronizing rod and the arc-changing roller conveyor. Since the height adjustment component acts indirectly on the synchronizing rod instead of directly on the arc-changing roller conveyor, the smoothness of the arc surface after bending of the arc-changing mechanism can be improved, thereby improving the arc-forming quality of the device. Through the spaced arrangement of the first and second fasteners, when the height adjustment component directly applies a vertical push-pull action to the second fastener, the adjacent second fastener can buffer this push-pull action when it is transferred to the first fastener within it. This prevents the arc-changing action of the arc-changing roller conveyor on the hot glass bottom surface from being too direct, thereby reducing the occurrence of shape defects such as insufficient smoothness of the multi-curved glass surface after tempering and cooling.

[0023] Preferably, the first fastener and the second fastener are fixedly connected and are located in the same adjustment direction as the height adjustment member.

[0024] By adopting the above technical solution, the first fastener and the second fastener are positioned to coincide in the height adjustment direction. This allows the advancement or retraction of the height adjustment component to directly act on the same point in the height direction of the synchronizing rod and the variable arc roller. As a result, the movement stroke of the screw sleeve can directly determine the curvature of the curved glass, thereby reducing processing errors. At the same time, it can also meet the tempering processing requirements of some products on the market that have a large degree of curvature.

[0025] Preferably, the cooling mechanism includes an upper air grating group composed of multiple upper air grates, each upper air grating including multiple upper air blowing boxes, each adjacent upper air blowing box being interconnected, the air blowing part of each upper air blowing box facing the variable arc roller conveyor, and each upper air blowing box having an air collecting box connected to the side away from the air blowing part.

[0026] The support frame also includes an upper support beam, and the upper wind grid assembly is disposed on the upper support beam.

[0027] Preferably, the cooling mechanism further includes a lower air grid group composed of multiple lower air grids, each lower air grid including multiple lower air blowing boxes, each adjacent lower air blowing box being interconnected, the air blowing part of each lower air blowing box facing the variable arc roller conveyor, and the side of each lower air blowing box away from the air blowing part being interconnected with the air collecting box; the lower air grid is located between adjacent synchronizing rods.

[0028] By adopting the above technical solution, the evenly distributed upper and lower air grids installed above and below the curved roller surface enable timely air tempering of the upper and lower surfaces of the hot glass after specific bending and forming. Simultaneously, the air blowing cloth, composed of multiple interconnected upper and lower air blowing boxes, continuously delivers uniform and controllable air pressure to the glass surface along the "floating" reciprocating transport path of the hot glass, forming a relatively stable airflow circulation. This reduces the generation of stress marks and improves the tempering production quality of multi-curved glass.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. This application enables the hot-state glass to maintain a synchronous bending relationship with the synchronous rods by using a single variable-arc roller conveyor with a synchronous rod arranged along the same length direction below it and multiple first fasteners arranged in a row. Furthermore, multiple height adjustment components are arranged along the length direction below the single synchronous rod, and a synchronous height change relationship is established between the two using second fasteners. When the height adjustment components cause multiple points on the synchronous rod connected by the second fasteners to change height, this height change is indirectly transmitted to the variable-arc roller conveyor, causing the single variable-arc roller conveyor to bend and deform at one or more points, presenting a single curve. When multiple variable-arc roller conveyors all bend and deform, the roller surface they collectively form exhibits a free-form surface state, thereby achieving secondary or multiple bending of the hot-state glass to meet the processing requirements of multi-curved tempered glass.

[0031] 2. This application sets the second fastener as a sliding connection structure between the hinge seat and the mounting seat, thereby maintaining a relatively sliding connection between the threaded sleeve and the synchronizing rod. Since the advancing or retracting movement of the threaded sleeve is vertical, for hot glass with different bending requirements, the threaded sleeve, which is fixedly pushed and retracted at a specific bending position, will tilt and swing under force. The sliding space between the hinge seat and the mounting seat will alleviate this in the direction perpendicular to the pushing and retracting of the threaded sleeve, thus keeping the screw structure basically vertical. The tilt angle of the screw is balanced by the sliding path of the hinge seat and the hinge rotation, further maintaining the stable and controllable performance of the height adjustment component when adjusting the height of the synchronizing rod. It can also reduce the tensile mechanical fatigue of the screw structure, improve the service life of mechanical components, and indirectly ensure the processing quality of curved tempered glass.

[0032] 3. This application improves the transmission efficiency and stability of the drive component for the screw by setting the lifting assembly as a mechanical linkage structure consisting of a bushing, a worm gear, an upper limit component, and a lower limit component. The lifting assembly is fitted onto the screw, fixing the positions of the bushing and the upper and lower limit components. The drive component directly drives the internal worm gear to rotate. Because the worm gear is limited by the upper and lower limit components, it cannot move in height, thus causing a relative change in the height of the screw body. This directly affects the protrusion or retraction of the screw, influencing the degree of convexity or concavity of the synchronous rod and the arc-changing roller conveyor, thereby increasing the bending processing range of the arc-changing mechanism.

[0045] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0046] This application discloses a tempering and forming apparatus 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.

[0047] 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. Arc-changing chain plates 23 are rotatably connected to both ends of each arc-changing roller conveyor 21 along its own length direction. The arc-changing chain plates 23 can be any one 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 23 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 transmission 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 support 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 after the previous process on the upper surface of the variable arc roller surface for cold swinging motion.

[0048] Meanwhile, the arc-changing chain plates 23 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 22, 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 23 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-bend shape, the lifting effect of the drive motor on the transmission cable needs to be reduced. Utilizing the weight of the variable-arc roller surface, the two ends of the variable-arc roller track 21 slowly descend, while the middle variable-arc roller track 21, due to its load-bearing connection with the support frame 1, forms a fulcrum (arc high point), allowing the entire variable-arc roller surface to slowly form a specific bending arc, thereby achieving the reverse bending processing of the hot glass. At this point, the above structure can basically achieve single-curve forming processing of hot glass, and the variable-arc roller track 21 can be either a rigid shaft or a flexible shaft.

[0049] Reference Figure 3 and Figure 4 The arc-changing mechanism 2 also includes an adjustment component 24 for adjusting the bending state of a single arc-changing roller conveyor 21. The number of adjustment components 24 is the same as the number of arc-changing roller conveyors 21. In this embodiment, an arc-changing roller conveyor 21 with its own elasticity, i.e., a flexible shaft roller conveyor, is required. Each adjustment component 24 includes a synchronizing rod 241 and multiple height adjustment components 25. The synchronizing rod 241 is located directly below a single arc-changing roller conveyor 21, and the length direction of the synchronizing rod 241 is consistent with the length direction of the arc-changing roller conveyor 21, both being arranged along the width direction of the support frame 1. The synchronizing rod 241 is also elastic; in this embodiment, the synchronizing rod 241 is made of spring steel wire. Multiple first fasteners 242 are installed at equal intervals between the arc-changing roller conveyor 21 and the synchronizing rod 241. The first fasteners 242 are rigid mechanical structures and can adopt a connection structure of clamps and bases to achieve a certain parallel distance between the arc-changing roller conveyor 21 and the synchronizing rod 241 while simultaneously changing the bending state. The number of first fasteners 242 is usually determined according to the bending requirements of the curved glass, typically set to 5-11, to help the hot glass form a smooth curved surface. Furthermore, the first fasteners 242 are usually installed between two adjacent transmission wheels, forming a regular and uniform arrangement to avoid mechanical interference.

[0050] Multiple height adjustment components 25 are equidistantly installed directly below the synchronizing rod 241 and extend along the length of the synchronizing rod 241. A second fastener 243 is installed at the connection between the height adjustment component 25 and the synchronizing rod 241 to establish a rotatable connection. In this embodiment, the height adjustment component 25 includes a screw 251, a threaded sleeve 252, a support base 253, and a driving component 254. The threaded sleeve 252 and the support base 253 are both threaded onto the screw 251, and the opening of the threaded sleeve 252 is welded to the upper surface of the support base 253. The length directions of the screw 251 and the threaded sleeve 252 are both along the height direction of the supporting frame 1 and perpendicular to the length direction of the synchronizing rod 241. The driving component 254 is installed at the bottom of the screw 251 and can drive the screw 251 to move the threaded sleeve 252 in a vertical direction for either a forward or retracting motion.

[0051] The second fastener 243 includes a hinge seat 2431 and a mounting seat 2432. There are two connection methods between the hinge seat 2431 and the mounting seat 2432 among the multiple second fasteners 243: a sliding connection between the hinge seat 2431 and the mounting seat 2432, and a fixed connection between the hinge seat 2431 and the mounting seat 2432. For multiple second fasteners 243 on a single synchronizing rod 241, the number of sliding connections needs to be higher than the number of fixed connections. In this embodiment, one set of hinge seats 2431 and mounting seats 2432 among the multiple second fasteners 243 on a single synchronizing rod 241 needs to be fixedly connected. When a sliding connection is established, the mounting seat 2432 has a groove on the side facing the hinge seat 2431, and the length direction of the groove is consistent with the length direction of the synchronizing rod 241. The hinge seat 2431 is provided with a snap-fit ​​strip or snap-fit ​​block on the side facing the mounting seat 2432, so as to completely install it inside the slide groove and establish a stable sliding connection relationship, so that the hinge seat 2431 can reciprocate and slide along the extension direction of the slide groove to the contact surface of the mounting seat 2432; when it is set as a fixed connection relationship, the connection between the hinge seat 2431 and the mounting seat 2432 can be directly welded. Meanwhile, the mounting base 2432 is fixedly sleeved on the body of the synchronizing rod 241, while the hinged base 2431 is hinged to the upper end of the threaded sleeve 252. This allows the height adjusting member 25, located on both sides away from the arc apex or apex (where the hinged base 2431 and mounting base 2432 are fixedly connected), to slide laterally between the mounting base 2432 and the hinged base 2431 when the height adjusting member 25 is pushed forward or retracted to indirectly cause the arc-shaped roller conveyor 21 to bend. This reduces the traction load on the height adjusting member 25 and keeps the screw 251 and threaded sleeve 252 as vertical as possible. Therefore, the opening length of the slide rail directly affects the tilt angle of the screw 251 and threaded sleeve 252.

[0052] It should be understood that the number of mounting seats 2432 and hinge seats 2431 with a fixed connection usually depends on the number of curved surfaces processed for the multi-curved glass, or the required degree of bending for irregular curved surfaces (such as those with an eccentric arc cross-section). In another embodiment of this application, the second fasteners 243 are all configured as the aforementioned mounting seats 2432 and hinge seats 2431 with a sliding connection. However, the difference is that a locking fastener is also installed between the sliding groove of the mounting seat 2432 and the snap-fit ​​structure of the hinge seat 2431 to restrict sliding. The locking fastener can be a snap-fit ​​or other limiting structure, thereby enabling the mounting seats 2432 and hinge seats 2431 to be directly adjusted or changed to be fixed or slidingly connected according to different multi-curved glass processing specifications on the same tempering forming device, further improving the applicability of the device.

[0053] Reference Figure 2 and Figure 3 The number of second fasteners 243 is the same as the number of height adjustment components 25, typically 5-11, and adjusted according to the processing requirements of the curved glass. The first fasteners 242 and second fasteners 243 are arranged at equal intervals on the synchronizing rod 241, thereby dispersing the direct pushing or retracting action of the second fasteners 243 between adjacent first fasteners 242, indirectly making the curved surface formed by the bending of the variable arc roller surface smoother. In another embodiment of this application, the first fasteners 242 and second fasteners 243 are fixedly connected, and their positions overlap in the height direction of the supporting frame 1. That is, the base of the first fastener 242 is directly welded to the mounting seat 2432 of the second fastener 243, and the mounting seat 2432 remains fixedly sleeved on the synchronizing rod 241. This arrangement allows the bending changes of the synchronizing rod 241 to be directly reflected on the variable arc roller conveyor 21, and the advancing or retracting stroke of the height adjusting component 25 can directly act on the variable arc roller conveyor 21 without conversion, thus achieving high adjustment accuracy. Similarly, without affecting the bending and forming of hot glass by the variable arc rollers, it is also possible to reasonably combine the staggered and overlapping arrangements.

[0054] Reference Figure 3 and Figure 5A lifting assembly 26 is also installed between the drive component 254 in the height adjustment component 25 and the screw 251. For a single variable-arc roller conveyor 21, multiple drive components 254 are integrated and installed on the lower support beam 11 of the support frame 1. The length direction of the lower support beam 11 is along the width direction of the support frame 1 and is located below the synchronous rod 241. The lifting assembly 26 includes a bushing 261, a worm gear 262, an upper limit component 263, and a lower limit component 264. The worm gear 262 is threaded onto the screw 251, and its rotation axis is along the length direction of the screw 251. The bushing 261 and the upper and lower limit components 264 are both sleeved on the screw 251. The worm gear 262 and the upper and lower limit components 264 are both located inside the bushing 261, with the worm gear 262 located between the upper and lower limit components 264. Positioning is achieved through the lower support beam 11, drive component 254, and bushing 261. In this embodiment, drive component 254 can be a motor, with the motor's output end passing through the housing of bushing 261 and meshing with worm gear 262. When the motor is started, it drives worm gear 262 to rotate. However, worm gear 262 is limited by the upper limit component 263 and lower limit component 264, preventing it from changing its height position. This, in turn, drives screw 251 to move in the height direction, enabling the screw 251 and bushing 252 structure to advance or retract the synchronizing rod 241, thus causing the variable arc roller conveyor 21 to bend. Because this device has high arc-changing accuracy, it typically requires a large number of height adjustment components 24 located below the variable arc roller surface. By mounting the motor on the lower support beam 11, with the motor's output end perpendicular to the length direction of the screw 251, this installation method significantly saves lower space and facilitates subsequent maintenance.

[0055] Reference Figure 1 and Figure 2The cooling mechanism 3 includes an upper air grid 31 group composed of multiple upper air grids 31 and a lower air grid 32 group composed of multiple lower air grids 32. The upper air grid 31 group is located above the variable arc roller surface and is fixedly installed on the upper support beam 12 extending from the bearing frame 1, and is used to heat the upper surface of the hot glass by blowing air. The lower air grid 32 group is located below the variable arc roller surface and is used to heat the lower surface of the hot glass by blowing air. The air source of both the upper air grid 31 group and the lower air grid 32 group is transmitted from the air collection box (not shown in the figure) through the air supply pipe. The length direction of each upper air grate 31 and each lower air grate 32 is consistent with the length direction of the variable arc roller conveyor 21. There is no specific limitation on the arrangement of the upper air grate 31, as long as the upper air grate 31 group can provide comprehensive and uniform air blowing tempering to the upper surface of the hot glass. As for the arrangement of the lower air grate 32, each lower air grate 32 needs to be installed between adjacent variable arc roller conveyors 21 to reduce the obstruction of air blowing by the rollers to the lower air grate 32, thereby ensuring that the hot glass can obtain a uniform and stable air blowing effect from the gap between adjacent variable arc roller conveyors 21 when it reciprocates. Each upper air grate 31 includes multiple upper air blowing boxes 311, and the air blowing part of each upper air blowing box 311 is composed of multiple sets of evenly opened air outlet holes, and the air blowing part faces the upper surface of the variable arc roller surface. Similarly, a single lower air grille 32 also includes multiple lower air boxes 321. The air blowing part of each lower air box 321 is composed of multiple sets of air outlet holes that are evenly opened, and the air outlets face the lower surface of the variable arc roller surface.

[0056] The air blowers can be configured to be interconnected or independent. When adjacent air blowers are interconnected, a duct is installed between them. The duct can be rigid or flexible, and the side of each air blower facing away from the blowing section is connected to the air collection box via an air supply pipe. Because the air blowers are interconnected, they can be spaced apart to organize the air supply pipe layout. When adjacent air blowers are independent, they are interconnected by rigid mechanical connections (such as chain plates), and each air blower receives independent cooling airflow through the air supply pipe. It should be understood that when the various air blowing boxes are interconnected through flexible tubes (such as corrugated tubes), adjustment components 24 with the same or similar structure can be installed on the upper and lower air grilles 32. Therefore, the upper and lower air grilles 32 can bend synchronously with the bending of the variable arc roller conveyor 21, so that the distance from which the cooling airflow blown from the air blowing box reaches the hot glass surface is approximately the same, further reducing the occurrence of stress wind spots on the curved glass surface.

[0057] 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 variable arc roller conveyor 21, and the arc lifting component 22 is activated to initially bend the hot glass to form the main curved state of the hot glass; the adjustment components 24 corresponding to different variable arc roller conveyors 21 are activated, and the lifting component 26 is driven by the drive component 254 to adjust the height of the screw sleeve 252 to advance or retract the positions of multiple second fasteners 243 on the synchronous rod 241. The synchronous rod 241 then transmits the advance or retraction to the variable arc roller conveyor 21 through multiple first fasteners 242 for secondary bending to form the secondary curved state of the hot glass; then the upper air grid 31 group and the lower air grid 32 group are activated to blow air to cool the bent hot glass, and multiple variable arc roller conveyors 21 are activated to reciprocate the bent hot glass along the conveying direction until the hot glass is tempered and formed.

[0058] The secondary bending process can be repeated multiple times to bend the hot glass in different directions after the first secondary bending, until the hot glass is shaped into the target composite bending state, and then air-cooled for tempering. Furthermore, the above processing steps, combined with the device's drive control mechanism, enable programmed precision control, reducing manpower input in the process and achieving highly automated and intelligent production. The drive control mechanism and other transmission structures can be installed outside the variable arc roller surface formed by the variable arc roller conveyor 21 without mechanically interfering with the variable arc mechanism 2. This ensures that the variable arc roller surface in this device is completely free from mechanical interference. After multiple composite bending of the hot glass, the bottom of the curved glass surface is supported by the variable arc roller conveyor 21. Subsequently, according to the bending shape of the glass, variable arc roller surfaces of corresponding support shapes are continuously formed in the glass conveying direction, achieving the processing effect of the hot glass "floating" on the variable arc roller surface. This ensures that each curved surface of the curved glass is always in contact with the variable arc roller surface during the cold swing motion, significantly reducing the probability of uncontrollable deformation of the curved glass. Meanwhile, compared to the large-amplitude undulation of hot glass during the cold swing motion of other processing devices, the forming method used in this application can "float" the hot glass on the surface of the variable arc roller 21, thereby reducing the undulation in the height direction, thus improving the controllable stability of the forming and tempering process, and providing a greater range of adjustable bending curvature for curved glass.

[0059] 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.
