Description

Technical Field

[0001] This utility model relates to the field of glass deep processing technology, and in particular to a wind grid assembly adjustment device and a glass forming equipment. Background Technology

[0002] In industries such as architectural decoration and automobile manufacturing, irregularly shaped glass is being used more and more widely. Among them, conical glass with different radii at both ends is experiencing rapid growth in market demand due to its unique appearance and mechanical performance advantages.

[0003] Rigid shaft roller conveyor tempering equipment has become the mainstream equipment for glass bending and tempering due to its high efficiency and stability. In the production of conical glass, the roller conveyor transports the raw glass sheet. Driven by servo motors, the variable-arc rollers on both sides of the conveyor precisely pull up different arcs according to a preset program, causing the forming roller to tilt at a specific angle. The tilt angle of the forming roller typically varies between 5° and 25° to meet the production needs of different specifications of conical glass. When the softened glass enters the forming area, it relies on its own weight and the auxiliary thrust of the roller conveyor to closely adhere to the surface of the tilted forming roller, gradually forming a conical profile with different radii at both ends. Simultaneously, the air grid assembly delivers cooling air to the glass surface at a strong wind speed of 20-30 meters per second to temper the glass.

[0004] However, traditional air grating assemblies are typically fixed structures or only suitable for flat glass processing. Their position and angle are difficult to dynamically adjust during equipment operation, making them unsuitable for the uniform airflow required when the forming rollers are tilted. Because the air grating assembly cannot maintain a suitable relative position and angle with the tilted forming rollers, the airflow distribution on the glass surface is severely uneven during the tempering process of conical glass bending. This results in inconsistent cooling rates across different parts of the glass, affecting the forming quality and mechanical properties, and ultimately limiting the production efficiency and product quality of conical glass. Utility Model Content

[0005] In order to overcome at least one of the defects of the prior art, one of the objectives of this utility model is to provide a wind grid assembly adjustment device, which can adjust the angle of the wind grid assembly through the variable arc component, thereby adjusting the angle between the cooling air blown out by the wind box and the glass surface, so as to achieve uniform wind force distribution on the glass surface; avoiding the problem that the traditional fixed-angle wind grid assembly cannot adjust the angle of the wind box, resulting in inconsistent cooling speed in different areas of the glass surface.

[0006] The second objective of this invention is to provide a glass forming device that can adjust the arc structure formed by the roller assembly through the arc-changing component, and at the same time, the arc-changing component can adjust the angle of the air grid assembly, so that the angle between the cooling air blown out by the air box and the glass surface is kept within a reasonable range, thereby achieving uniform wind force distribution on the glass surface; thus avoiding the problem that the traditional fixed-angle air grid assembly can only be used in flat glass processing scenarios.

This adjusts the angle between the cooling air blown by the windbox and the glass surface. By controlling the angle within a reasonable range, uniform airflow distribution on the glass surface is achieved. Simultaneously, the first connecting part of the windbox slides into the first connecting member of the first arc-changing component. This allows the sliding movement between the first connecting part and the first connecting member during the tilting process to compensate for the length change of the windbox between the two arc-changing mechanisms caused by the windbox tilt, enabling the windbox to adaptively adjust its angle and position.

Simultaneously, the bellows in the air grid assembly adjustment device can adjust its posture, angle, and position in real time according to the movement of the arc-changing mechanism. During the glass arc-changing process, the airflow conveyed by the bellows can apply uniform pressure to the glass surface, assisting the glass in conforming to the shape of the conveying rollers, further improving the accuracy and quality of glass forming, and avoiding problems such as inconsistent glass deformation and uneven surface.

[0042] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0043] Example 1

[0044] See Figure 1 and Figure 2This utility model discloses a windshield assembly adjustment device, which includes a windshield assembly and a variable arc assembly. Specifically, the windshield assembly includes a wind box 10, with a first connecting portion 11 and a second connecting portion 12 at both ends of the wind box 10. The variable arc assembly includes a first variable arc mechanism 20 and a second variable arc mechanism 30, which are respectively disposed at both ends of the windshield assembly. The first variable arc mechanism 20 includes multiple mutually hinged first variable arc members 21, each with a first connecting member 22, which is hinged to and slidably connected to the first connecting portion 11. Simultaneously, the second variable arc mechanism 30 includes multiple mutually hinged second variable arc members 31, each with a second connecting member 32, which is hinged to the second connecting portion 12. The first connecting member 22 is used to slide and engage with the first connecting portion 11 when the wind box 10 is in an inclined state.

[0045] Based on this structure, when using the wind grid assembly adjustment device of this utility model, when the first arc-changing mechanism 20 and the second arc-changing mechanism 30 change arcs synchronously, the first arc-changing component 21 and the second arc-changing component 31 connected to the same wind box 10 have the same rotation angle. Therefore, the first connecting part 11 and the second connecting part 12 at both ends of the wind box 10 are synchronously lifted to the same height position under the drive of the first arc-changing component 21 and the second arc-changing component 31. During this process, the wind box 10 remains horizontal.

[0046] See Figure 2 and Figure 3 When the first arc-changing mechanism 20 and the second arc-changing mechanism 30 perform asynchronous arc-changing, the rotation angles of the first arc-changing component 21 and the second arc-changing component 31 connected to the same bellows 10 are different. Therefore, the first connecting part 11 and the second connecting part 12 at both ends of the bellows 10 will be lifted to different height positions under the action of the first arc-changing component 21 and the second arc-changing component 31. During this process, the first connecting part 11 of the bellows 10 rotates and slides relative to the first connecting part 22 on the first arc-changing component 21, and the second connecting part 12 of the bellows 10 rotates relative to the second connecting part 32 on the second arc-changing component 31, causing the bellows 10 to perform adaptive angle and position adjustments so that the bellows 10 gradually changes from a horizontal state to an inclined state.

[0047] It should be noted that the asynchronous arc changing of the first arc changing mechanism 20 and the second arc changing mechanism 30 refers to the first arc changing mechanism 20 and the second arc changing mechanism 30 bending with different radii of curvature. Specifically, this is achieved by rotating the corresponding first arc changing component 21 and second arc changing component 31 on the first arc changing mechanism 20 and the second arc changing mechanism 30 by different angles.

[0048] The bellows 10 is hinged to the variable arc mechanism at both ends, allowing the bellows 10 to rotate relative to the first variable arc mechanism 21 and the second variable arc mechanism 31, thus changing its angle. The bellows 10 can switch between a horizontal and a tilted state. Simultaneously, since the distance between the first variable arc mechanism 20 and the second variable arc mechanism 30 remains constant, and the first connecting part 11 of the bellows 10 slides with the first connecting part 22 of the first variable arc mechanism 21, the sliding motion between the first connecting part 11 and the first connecting part 22 during tilting compensates for the length change of the bellows 10 between the two variable arc mechanisms caused by its tilt, allowing the bellows 10 to adaptively adjust its angle and position.

[0049] It should be further noted that a roller conveyor assembly is also provided between the first arc-changing mechanism 20 and the second arc-changing mechanism 30. The roller conveyor assembly includes multiple conveying rollers 80, which are arranged at intervals along a conveying direction. Each conveying roller 80 has its two ends connected to the corresponding first arc-changing member 21 and second arc-changing member 31. The extending direction of the air box 10 is the same as that of the conveying rollers 80, and the multiple air boxes 10 are also arranged at intervals along the conveying direction. Each air box 10 is installed in the gap between two conveying rollers 80, located at the lower and / or upper part of the conveying rollers 80. (See reference...) Figure 7 When the bellows 10 is located at the lower part of the conveyor roller 80, the bellows 10 and the conveyor roller 80 can be driven to change arc by the same first arc-changing mechanism 20 and second arc-changing mechanism 30; when the bellows 10 is located at the upper part of the conveyor roller 80, the bellows 10 and the conveyor roller 80 are driven to change arc by different first arc-changing mechanisms 20 and second arc-changing mechanisms 30.

[0050] The following description assumes that the bellows 10 is located at the lower part of the conveyor roller 80, and the bellows 10 and the conveyor roller 80 are driven to change arc by the same first arc-changing mechanism 20 and second arc-changing mechanism 30: Specifically, when the first arc-changing mechanism 20 and the second arc-changing mechanism 30 change arc synchronously, the first arc-changing component 21 and the second arc-changing component 31 connected to the same conveyor roller 80 have the same rotation angle. Therefore, the first connecting part 11 and the second connecting part 12 at both ends of the conveyor roller 80 are lifted to the same height position under the drive of the first arc-changing component 21 and the second arc-changing component 31. During this process, the conveyor roller 80 remains horizontal, and the multiple horizontal conveyor rollers 80 have an arc structure in the conveying direction.

[0051] Under the force of multiple conveyor rollers 80, the softened glass 90 on the roller assembly is bent into an arc-shaped glass 90 with the same radius of curvature at both ends. At this time, since the bellows 10 is also in a horizontal state, and the multiple horizontal bellows 10 are also in an arc-shaped structure in the conveying direction, the distance between the bellows 10 and the conveyor rollers 80 at each position in the length direction is the same, and the angle between the cooling air blown out by the bellows 10 and the glass surface on the conveyor rollers 80 is close to 90°, the bellows 10 can uniformly blow air to temper the arc-shaped glass 90 on the conveyor rollers 80.

[0052] When the first arc-changing mechanism 20 and the second arc-changing mechanism 30 change arcs asynchronously, the first arc-changing component 21 and the second arc-changing component 31 connected to the same conveying roller 80 have different rotation angles. Therefore, the first connecting part 11 and the second connecting part 12 at both ends of the conveying roller 80 are lifted to different height positions under the drive of the first arc-changing component 21 and the second arc-changing component 31. At this time, the conveying roller 80 is in an inclined state, and multiple inclined conveying rollers 80 have an arc-shaped structure in the conveying direction. Moreover, the arc-shaped structure has different radii of curvature at both ends of the length of the conveying roller 80. Under the action of multiple conveying rollers 80, the softened glass 90 on the conveying roller 80 is bent into a conical arc-shaped glass 90 with different radii of curvature at both ends.

[0053] At this time, since the bellows 10 is also in an inclined state, and the multiple inclined bellows 10 are also in an arc-shaped structure with different radii of curvature at both ends in the conveying direction, the distance between the bellows 10 and the conveying roller 80 at each position in the length direction is the same, and the angle between the cooling air blown out by the bellows 10 and the glass surface on the conveying roller 80 is close to 90°, so the bellows 10 can still uniformly blow air to temper the arc-shaped glass 90 on the conveying roller 80.

[0054] When the conveyor roller 80 is tilted into position and the softened glass 90 adheres to the tilted conveyor roller 80, the air grid assembly begins to supply air for cooling. Throughout the cooling process, if the angle of the conveyor roller 80 changes due to the shape of the glass 90 or process requirements, the first connector 22 will continuously slide and engage with the first connector 11 while the air box 10 is tilted. The second connector 32 and the second connector 12 will also rotate and adjust in coordination to ensure that the air grid assembly can always supply air evenly to the glass 90 on the conveyor roller 80 at a suitable angle and position until the glass 90 is tempered.

[0055] Therefore, this application achieves this by hinged and sliding connection between the arc-changing component and the bellows 10, allowing the arc-changing component to simultaneously drive the air grid assembly to tilt in accordance with the tilt angle of the conveyor roller 80 while driving the conveyor roller 80 to a specific tilt angle. Since the air grid assembly can adjust its angle and position in real time, the angle between the cooling air blown out by the bellows 10 and the glass surface on the conveyor roller 80 is adjustable. By controlling the angle between the cooling air and the glass surface within a reasonable range, uniform wind force distribution on the glass surface can be achieved.

[0056] As an optional implementation method, see [link / reference]. Figure 4 as well as Figure 5 The first connecting part 11 is connected to the first connecting member 22 via the first ball hinge 40, and the second connecting part 12 is connected to the second connecting member 32 via the second ball hinge 50.

[0057] Based on this structure, when the first arc-changing mechanism 20 and the second arc-changing mechanism 30 simultaneously change arcs, the first connecting part 11 and the second connecting part 12 at both ends of the bellows 10 are simultaneously lifted to the same height position under the drive of the first and second arc-changing components 31, and the bellows 10 remains horizontal. During this process, the first ball hinge 40 and the second ball hinge 50 allow relative rotation between the first connecting part 11 and the first connecting component 22, and between the second connecting part 12 and the second connecting component 32. Since the ball hinge has three degrees of rotational freedom, it can flexibly rotate around three orthogonal axes within a certain range. This allows the bellows 10 to adjust its posture automatically through the rotation of the ball hinge during the lifting process, even if it is subjected to a small lateral force or an angular deviation caused by assembly errors, and always remain horizontal. This ensures the relative position stability of the bellows 10 and the conveying roller 80, providing a reliable guarantee for subsequent uniform blowing and tempering.

[0058] When the first arc-changing mechanism 20 and the second arc-changing mechanism 30 perform asynchronous arc-changing, the two ends of the bellows 10 are lifted to different heights, and the bellows 10 gradually changes from a horizontal state to an inclined state. At this time, the first connecting part 11 rotates and slides relative to the first connecting part 22 on the first arc-changing member 21, and the second connecting part 12 rotates relative to the second connecting part 32 on the second arc-changing member 31. The first ball hinge 40, with its three degrees of rotational freedom, not only meets the rotational requirements of the first connecting part 11 relative to the first connecting part 22, but also allows for multi-directional rotation and fine-tuning as the relative position between the first connecting part 11 and the first connecting part 22 changes due to the inclination during the tilting process of the bellows 10. Similarly, the second ball hinge 50, in conjunction with the rotation of the second connecting part 12 and the second connecting part 32, enables adaptive adjustment of the tilt angle and position of the bellows 10. Furthermore, during the entire tilting process, the rotational characteristics of the first ball hinge 40 also assist the sliding fit between the first connecting part 11 and the first connecting member 22, better compensating for the length change between the two variable arc mechanisms caused by the tilting of the bellows 10.

[0059] Therefore, the multi-directional rotation capability of the ball joint allows the bellows 10 to be adjusted at multiple angles in three-dimensional space, ensuring that the cooling air is always blown onto the surface of the glass 90 at a suitable angle, maintaining a uniform airflow distribution on the surface of the glass 90 until the glass 90 is tempered. Compared with ordinary hinge methods, it can more accurately and flexibly adapt to the tilt changes of the bellows 10 when the arc-changing mechanism changes arc asynchronously, as well as the dynamic adjustment of the angle of the conveyor roller 80 during the cooling process, avoiding motion interference or limited angle adjustment problems caused by insufficient freedom of connection method.

[0060] As an optional implementation method, see [link / reference]. Figure 4 The first connecting part 11 includes a first connecting hole, and the inner peripheral wall of the first connecting hole is provided with a first spherical rotating groove 111. The aforementioned first spherical hinge 40 includes a first sphere 41, and the first connecting member 22 includes a first connecting shaft 221. The first sphere 41 is mounted on the outer periphery of the first connecting shaft 221, the first connecting shaft 221 is mounted in the first connecting hole, and the first sphere 41 is rotatably connected to the first spherical rotating groove 111. At the same time, the first sphere 41 is slidably connected to the first connecting shaft 221.

[0061] Based on this structure, during assembly, the first sphere 41 can be first installed on the outer periphery of the first connecting shaft 221, with the first sphere 41 and the first connecting shaft 221 achieving a slidable connection through a clearance fit. Then, the first connecting shaft 221 is inserted into the first connecting hole, simultaneously embedding the first sphere 41 into the first spherical rotating groove 111 within the hole. The curved surface of the first spherical rotating groove 111 fits against the first sphere 41 to form a ball-joint structure.

[0062] When the first arc-changing mechanism 20 and the second arc-changing mechanism 30 simultaneously change arcs, the first connecting part 11 and the second connecting part 12 at both ends of the bellows 10 are lifted to the same height, and the bellows 10 remains horizontal. During this process, the first ball 41 can rotate slightly within the first spherical rotating groove 111 to compensate for small angular deviations caused by assembly errors or the arc-changing process, ensuring that the bellows 10 rises smoothly. Since the bellows 10 is horizontal, the first ball 41 does not slide axially on the first connecting shaft 221, and its posture is finely adjusted only through the rotational degree of freedom of the ball joint.

[0063] When the first arc-changing mechanism 20 and the second arc-changing mechanism 30 change arcs asynchronously, the height difference between the two ends of the bellows 10 causes the bellows 10 to tilt. At this time, the first ball 41 rotates significantly within the first spherical rotating groove 111 to adapt to the tilt angle of the bellows 10. Simultaneously, the tilt of the bellows 10 causes its projected length between the two arc-changing mechanisms to shorten. At this time, the first ball 41 drives the first connecting part 11 to slide axially along the first connecting shaft 221 to compensate for this length change and prevent the structure from jamming.

[0064] Thus, the first connecting part 11 and the first connecting piece 22, through the combined action of the rotational degree of freedom of the first ball hinge 40 and the translational degree of freedom of the sliding pair, meet the multi-dimensional motion requirements under complex working conditions, realizing the adaptive angle adjustment and length compensation of the bellows 10 during the arc-changing process. By rotating the first ball hinge 40, the angle and position of the air outlet surface of the bellows 10 can be adjusted to be parallel to the conveying roller 80, ensuring that the cooling air at all points on the air outlet surface has the same angle with the surface of the glass 90, eliminating wind dead angles, and significantly improving the tempering equipment's processing capability and tempering quality for complex curved glass 90.

[0065] In addition, the end of the first connecting shaft 221 can be prevented from sliding out by a snap ring, shoulder or threaded locking device.

[0066] As an optional implementation method, see [link / reference]. Figure 5 The second connecting part 12 includes a second connecting hole, and the inner peripheral wall of the second connecting hole is provided with a second spherical rotating groove 121. The aforementioned second spherical hinge 50 includes a second sphere 51, and the second connecting member 32 includes a second connecting shaft 321, with the second sphere 51 mounted on the outer periphery of the second connecting shaft 321. The second connecting shaft 321 is mounted in the second connecting hole, and the second sphere 51 is rotatably connected to the second spherical rotating groove 121.

[0067] Based on this structure, during assembly, the second sphere 51 can be first installed on the outer periphery of the second connecting shaft 321, with the second sphere 51 and the second connecting shaft 321 having an interference fit. Then, the second connecting shaft 321 is inserted into the second connecting hole, while the second sphere 51 is embedded in the second spherical rotating groove 121 within the hole. The curved surface of the second spherical rotating groove 121 fits against the second sphere 51 to form a ball-joint structure.

[0068] When the first arc-changing mechanism 20 and the second arc-changing mechanism 30 simultaneously change arcs, the first connecting part 11 and the second connecting part 12 at both ends of the bellows 10 are lifted to the same height, and the bellows 10 remains horizontal. During this process, the second ball 51 rotates slightly in the spherical rotating groove to compensate for small angular deviations caused by assembly errors or the arc-changing process, ensuring that the bellows 10 rises smoothly.

[0069] When the first arc-changing mechanism 20 and the second arc-changing mechanism 30 change arcs asynchronously, the height difference between the two ends of the bellows 10 causes the bellows 10 to tilt. At this time, the second ball 51 rotates significantly within the second spherical rotating groove 121 to adapt to the tilt angle of the bellows 10.

[0070] Therefore, the three rotational degrees of freedom of the second ball hinge 50 allow the second connector 32 to adapt to subtle changes in the posture of the bellows 10, avoiding structural stress caused by rigid constraints. At the same time, the rotation of the second ball hinge 50 and the sliding-rotational combined motion of the first ball hinge 40 work together to keep the bellows 10 stably connected during tilting, while compensating for length changes caused by tilting.

[0071] As an optional implementation, the second connecting shaft 321 is provided with two stops 323, which are respectively disposed at both ends of the second sphere 51.

[0072] Specifically, the two stops 323 can be retaining rings and / or shoulders mounted on the second connecting shaft 321. An annular groove can be machined at a corresponding position on the second connecting shaft 321, and the elastic retaining ring can be embedded in the groove, with the retaining ring abutting against the end of the second ball 51 to form an axial limit. Alternatively, a stepped structure can be formed on the second connecting shaft 321 by turning or forging, with one shoulder directly restricting the movement of the ball, and the other side locked by a nut or gland.

[0073] Therefore, the two stops 323 restrict the axial movement of the second ball 51, ensuring that the ball rotates in the center within the spherical rotating groove, and avoiding jamming of the ball joint or uneven wear caused by axial offset.

[0074] As an optional implementation, the bellows 10 has a first end plate 13 and a second end plate 14 at both ends, with a first connecting portion 11 formed on the first end plate 13 and a second connecting portion 12 formed on the second end plate 14. (See also...) Figure 3 and Figure 6 The first end plate 13 is also provided with a third connecting part 15, and the first arc-changing member 21 is also provided with a toggle member 23. The toggle member 23 is installed on the third connecting part 15, and the toggle member 23 is used to drive the third connecting part 15 to rotate around the first connecting part 11 when the first arc-changing member 21 rotates.

[0075] Based on this structure, during assembly, the first end plate 13 and the second end plate 14 are fixed at both ends of the bellows 10 by welding or bolting. The first connecting part 11 and the second connecting part 12 are respectively integrated on the end plates and connected to the first connecting part 22 on the first arc-changing member 21 and the second connecting part 32 on the second arc-changing member 31 by ball joints. At the same time, the actuating part 23 of the first arc-changing member 21 is inserted into the third connecting part 15 of the first end plate 13.

[0076] When the first arc-changing mechanism 20 and the second arc-changing mechanism 30 change arcs synchronously, the first arc-changing component 21 and the second arc-changing component 31 will rotate at the same rotation angle, thereby pulling both ends of the bellows 10 to the same height. During this process, the actuating component 23 of the first arc-changing component 21 rotates with the arc-changing component, and through its cooperation with the third connecting part 15, generates a rotational driving torque around the first connecting part 11. This torque will drive the first end plate 13 and the entire bellows 10 to rotate synchronously around the first connecting part 11 at the same angle as when the first arc-changing component 21 changes arc.

[0077] At this time, the height of both ends of the bellows 10 in the vertical direction remains consistent, maintaining a horizontal posture. However, after the third connecting part 15 is rotated by the actuating component 23, the air outlet surface of the bellows 10 is precisely adjusted to be parallel to the conveying surface of the conveying roller 80. In this way, the bellows 10 can more accurately correspond to the gap between the two conveying rollers 80, ensuring that the cooling air blown from the bellows 10 can evenly cover the glass 90 surface on the conveying roller 80, effectively improving the uniformity of the tempering effect.

[0078] When the first arc-changing mechanism 20 and the second arc-changing mechanism 30 change arcs asynchronously, the first arc-changing component 21 and the second arc-changing component 31 will have different rotation angles. This will cause the two ends of the bellows 10 to be lifted to different heights, making the bellows 10 tilt. During this process, the actuating component 23 of the first arc-changing component 21 will still rotate with the arc-changing component, and through the third connecting part 15, drive the first end plate 13 and the end of the bellows 10 close to the first arc-changing component 21 to rotate around the first connecting part 11 at the same angle as when the first arc-changing component 21 changes arc.

[0079] At this time, the bellows 10 is tilted, and a small angle is formed between the air outlet surface of the bellows 10 and the conveying surface of the conveying roller 80. This precise adjustment of the angle allows the air outlet direction of the bellows 10 to better fit the tilted surface of the glass 90 on the conveying roller 80, ensuring that the cooling air can act on the glass 90 at a better angle.

[0080] During the entire arc-changing process, the first ball hinge 40 and the second ball hinge 50 allow the bellows 10 to make minor adjustments to its posture within a small range, effectively compensating for deviations caused by manufacturing errors, assembly errors, and vibrations during equipment operation, so that the bellows 10 always maintains a parallel or reasonable tilted relationship with the conveyor roller 80.

[0081] Therefore, the cooperation between the actuating component 23 and the third connecting part 15 ensures that the bellows 10 can follow the angle change of the conveyor roller 80 in real time and accurately during the arc-changing process. Whether in synchronous or asynchronous arc-changing conditions, the angle between the cooling air and the surface of the glass 90 can be made as close to perpendicular as possible, effectively avoiding the problem of uneven tempering stress on the surface of the glass 90 caused by the deviation of the blowing angle, and significantly improving the tempering quality and finished product qualification rate of the glass 90.

[0082] As an optional implementation, the actuating member 23 includes an actuating shaft, and the third connecting part 15 includes a mounting groove, wherein the two ends of the actuating shaft along the rotation direction of the first variable arc member 21 respectively abut against the groove wall of the mounting groove, and the actuating shaft can slide along the mounting groove to approach or move away from the first connecting part 11.

[0083] Based on this structure, the actuating shaft can be fixed in the mounting hole of the first variable arc component 21 by interference fit or key connection. The mounting groove is opened in the third connecting part 15 of the first end plate 13. The groove width is slightly larger than the diameter of the actuating shaft. The actuating shaft can slide freely in the groove without obvious shaking. When the bellows 10 is in a horizontal state, the actuating shaft is located in the middle position of the mounting groove.

[0084] When the first arc-changing mechanism 20 and the second arc-changing mechanism 30 change arcs, the first arc-changing component 21 rotates, and the actuating shaft rotates synchronously with the first arc-changing component 21. At this time, one end of the actuating shaft along the rotation direction abuts against the groove wall of the mounting groove, and transmits torque through friction, pushing the third connecting part 15 and the first end to rotate around the first connecting part 11.

[0085] Since the rotation trajectory of the first arc-changing component 21 is an arc, while the movement trajectory of the third connecting part 15 is a circle centered on the first connecting part 11, there is a radial displacement difference between the two. The actuating shaft slides away from the first connecting part 11 within the mounting groove to compensate for this displacement difference and prevent the structure from jamming. In addition, when the entire bellows 10 moves closer to or away from the roller conveyor assembly under the drive of the wind grid drive assembly, the mounting groove can also guide the actuating shaft, so that the distance between the air outlet surface and the glass surface on the roller conveyor assembly can be adjusted while keeping the air outlet angle unchanged.

[0086] As an optional implementation, the first arc-changing member 21 is further provided with a fourth connecting portion, and the first connecting member 22 is detachably installed on the fourth connecting portion. The second arc-changing member 31 is provided with a fifth connecting portion, and the second connecting member 32 is detachably installed on the fourth connecting portion.

[0087] Based on this structure, during assembly, the first connecting member 22 can be installed onto the fourth connecting part of the first arc-changing member 21 using connection methods such as bolt connection, snap connection, or pin connection. Taking bolt connection as an example, firstly, corresponding threaded holes are machined on the fourth connecting part and the first connecting member 22, and then bolts are passed through the threaded holes of both and tightened to ensure that the first connecting member 22 is securely installed on the fourth connecting part.

[0088] Similarly, the second connector 32 is also installed on the fifth connecting part of the second variable arc member 31 through the same or similar detachable connection method. Subsequently, the first connector 22 is connected to the first connecting part 11 of the air box 10 through the first ball hinge 40, and the second connector 32 is connected to the second connecting part 12 of the air box 10 through the second ball hinge 50, thus completing the overall assembly of the air grid assembly adjustment device.

[0089] When the first arc-changing mechanism 20 and the second arc-changing mechanism 30 perform arc-changing operations, the first connecting member 22 installed in the fourth connecting part and the second connecting member 32 installed in the fifth connecting part respectively drive the first connecting part 11 and the second connecting part 12 of the bellows 10, evenly lifting both ends of the bellows 10 to the height of the arc-changing component. During this process, the connection between the fourth connecting part and the first connecting member 22, and between the fifth connecting part and the second connecting member 32, is stable, ensuring the stable transmission of the arc-changing motion.

[0090] Therefore, the individual replacement of components is achieved through detachable connections, avoiding the need to replace the entire arc-changing component or wind grid assembly due to the damage of a single component, thus effectively reducing the maintenance cost of the equipment.

[0091] As an optional implementation, the louver assembly adjustment device further includes a louver drive assembly, which includes a first drive member 60 and a second drive member 61. The fourth connecting portion includes a first slide rail 24, and the first connecting member 22 includes a first mounting base 222, which is slidably connected to the first slide rail 24. The first drive member 60 drives the first mounting base 222. Furthermore, the fifth connecting portion includes a second slide rail 33, and the second connecting member 32 includes a second mounting base 322, which is slidably connected to the second slide rail 33. The second drive member 61 drives the second mounting base 322 to slide.

[0092] Based on this structure, during assembly, the first mounting base 222 can form a sliding pair with the first slide rail 24 via a slider, and the first driving member 60 is mounted on the first arc-changing member 21 via the first mounting bracket 25, with the power output end of the first driving member 60 fixedly connected to the first mounting base 222. Similarly, the second mounting base 322 can form a sliding pair with the second slide rail 33 via a slider, and the second driving member 61 is mounted on the second arc-changing member 31 via the second mounting bracket 34, with the power output end of the second driving member 61 fixedly connected to the second mounting base 322.

[0093] In use, the posture of the bellows 10 is first adjusted by rotating the first variable arc member 21 and the second variable arc member 31. When the first variable arc member 21 and the second variable arc member 31 rotate synchronously, the bellows 10 is in a horizontal posture; if the two rotate at different angles, the bellows 10 is in a tilted posture. At the same time, the actuating shaft on the first variable arc member 21 adjusts the air outlet angle of the bellows 10 by cooperating with the third connecting part 15 of the first end plate 13, so that the air outlet of the bellows 10 maintains a suitable relative angle with the conveying surface of the conveying roller 80, ensuring that the cooling air can be blown onto the glass 90 at a suitable angle.

[0094] After adjusting the posture and air outlet angle of the bellows 10, further operations can be performed using the first drive unit 60 and the second drive unit 61. When the bellows 10 needs to be close to the conveyor roller 80, the first drive unit 60 and the second drive unit 61 start synchronously, driving the first mounting base 222 and the second mounting base 322 to slide forward along their respective slide rails, causing the bellows 10 to smoothly approach the conveyor roller 80 as a whole, thereby reducing the distance between the bellows 10 and the glass 90 and enhancing the blowing effect; conversely, when the bellows 10 needs to be away from the conveyor roller 80, the first drive unit 60 and the second drive unit 61 drive the first mounting base 222 and the second mounting base 322 to slide backward, causing the bellows 10 to move backward as a whole, increasing the distance between the bellows 10 and the glass 90, and meeting different process requirements.

[0095] Therefore, the sliding pair arrangement of the first mounting base 222 and the first slide rail 24, and the second mounting base 322 and the second slide rail 33, combined with the precise drive of the driving component, can achieve precise control of the position of the air box 10, ensuring that the air box 10 and the glass 90 on the conveying roller 80 maintain a suitable distance, thereby ensuring that the glass 90 can obtain uniform and stable cooling air force during the tempering process, effectively improving the tempering quality and yield of the glass 90.

[0096] Both the first driving component 60 and the second driving component 61 include a servo motor and a ball screw mechanism. Specifically, the ball screw nut is connected to the mounting base. When the servo motor runs, the rotation of the ball screw drives the nut to move linearly, thereby driving the mounting base to slide. Alternatively, the first driving component 60 and the second driving component 61 may also include a motor and an electric push rod. The end of the electric push rod is connected to the mounting base. When the motor runs, the extension and retraction of the electric push rod can directly drive the mounting base to slide.

[0097] As an optional implementation, the wind grid assembly includes a plurality of wind boxes 10, which are arranged along a straight line. Simultaneously, a plurality of first arc-changing members 21 are arranged along a straight line, with adjacent first arc-changing members 21 hinged together; a plurality of second arc-changing members 31 are also arranged along a straight line, with adjacent second arc-changing members 31 hinged together.

[0098] Based on this structure, during assembly, multiple air boxes 10 are arranged sequentially along the straight line of the conveying direction of the conveying roller 80, with a precise spacing between adjacent air boxes 10 to ensure continuous and uniform cooling air coverage. A first end plate 13 and a second end plate 14 are fixed to both ends of each air box 10, and a first connecting part 11 and a second connecting part 12 are correspondingly formed on the end plates.

[0099] Subsequently, multiple first arc-changing components 21 are arranged sequentially along a straight line at one end of the bellows 10 assembly. Adjacent first arc-changing components 21 are hinged together by hinge shafts, allowing relative rotation between them. The first connecting shaft 221 on the first arc-changing component 21 is connected to the first connecting hole of the first connecting part 11 via a first ball joint 40. Similarly, at the other end of the bellows 10 assembly, multiple second arc-changing components 31 are arranged along a straight line and hinged together. The second connecting shaft 321 on the second arc-changing component 31 is connected to the second connecting hole of the second connecting part 12 via a second ball joint 50.

[0100] When synchronous arcing of the glass 90 is required, the control system issues a command, and multiple first arcing components 21 and second arcing components 31 in the first arcing mechanism 20 and the second arcing mechanism 30 move synchronously. Since adjacent arcing components are hinged together, the arcing action is transmitted sequentially, making the entire arcing mechanism bend as a whole. During this process, each first arcing component 21 drives the first connecting component 22 connected to it, and pulls the first end plate 13 of the corresponding bellows 10 through the first ball hinge 40; the second arcing component 31 pulls the second end plate 14 of the bellows 10 through the second ball hinge 50.

[0101] Because the two variable arc components connected to the same bellows 10 rotate synchronously at the same angle, both ends of each bellows 10 are evenly lifted to the same height, and each bellows 10 maintains a horizontal posture. At the same time, because the two connected first variable arc components 21 or the two connected second variable arc components 31 rotate at different angles, multiple horizontally oriented bellows 10 are lifted to different heights, and the multiple bellows 10 present an arc-shaped arrangement along a straight line.

[0102] When dealing with conical glass 90 with different radii of curvature at both ends, the first arc-changing mechanism 20 and the second arc-changing mechanism 30 perform asynchronous arc-changing. At this time, the two arc-changing components connected to the same bellows 10 rotate at different angles, and the connected multiple first arc-changing components 21 and multiple second arc-changing components 31 each rotate at different angles. On the side of the first arc-changing mechanism 20, the angular differences of the multiple first arc-changing components 21 cause the bellows 10 connected to them to be lifted to different heights at one end; similarly, the multiple second arc-changing components 31 on the side of the second arc-changing mechanism 30 also cause different height changes at the other end of the bellows 10. In this way, the multiple bellows 10 as a whole exhibit different degrees of tilt, forming a continuous tilt angle change along the straight line that conforms to the requirements of the curved surface of the glass 90.

[0103] Therefore, the combination of multiple bellows 10 and the arc-changing component enables the tempering of glass 90 of different shapes. Whether it is an arc-shaped glass 90 with the same radius of curvature at both ends, or a conical arc-shaped glass 90 with different radii of curvature at both ends, the bellows 10 can be adjusted to the corresponding posture and angle by controlling the synchronous or asynchronous arc-changing component, ensuring that the cooling air evenly covers the surface of the glass 90 and meeting diverse production needs.

[0104] Furthermore, adjacent arc-changing components are hinged together to form a stable linkage structure. During the arc-changing process, force can be evenly transmitted to each arc-changing component and the connected conveyor roller 80, so that multiple conveyor rollers 80 can continuously change arcs.

[0105] As an optional implementation, both the first arc-changing member 21 and the second arc-changing member 31 include a T-plate. Specifically, the T-plate includes a first plate segment 70 and a second plate segment 71, with the second plate segment 71 disposed on the top of the first plate segment 70. The second plate segment 71 is provided with a first mounting hole 72 and a second mounting hole 73 spaced apart. The first mounting hole 72 is hinged to the second mounting hole 73 on an adjacent T-plate on one side, and the second mounting hole 73 is hinged to the first mounting hole 72 on an adjacent T-plate on the other side.

[0106] Based on this structure, during assembly, multiple T-plates are arranged sequentially along a straight line. On the second segment 71 of each T-plate, the first mounting hole 72 is connected to the second mounting hole 73 of the adjacent T-plate via a hinge shaft, forming an alternating hinge structure. The first segment 70 of the T-plate is fixedly connected to either a first connector 22 or a second connector 32, and is connected to the end plate of the bellows 10 via a ball joint.

[0107] It should be noted that the conveyor roller 80 is disposed between the first arc-changing component 21 and the second arc-changing component 31, and both ends of the conveyor roller 80 are respectively connected to the first mounting hole 72 or the second mounting hole 73 correspondingly provided on the first arc-changing component 21 and the second arc-changing component 31. In this way, when the first arc-changing mechanism 20 and the second arc-changing mechanism 30 drive multiple first arc-changing components 21 and multiple second arc-changing components 31 to form an arc shape, they can synchronously drive the roller conveyor assembly to form an arc shape.

[0108] When the first arc-changing mechanism 20 and the second arc-changing mechanism 30 change arcs synchronously, the control system drives all T-plates to rotate synchronously. Since adjacent T-plates are connected by alternating hinge holes, they form a continuous arc trajectory during rotation, causing the entire first arc-changing component group 21 and the second arc-changing component group 31 to bend synchronously. The two ends of the bellows group 10 are evenly lifted to maintain a horizontal posture.

[0109] When the first arc-changing mechanism 20 and the second arc-changing mechanism 30 change arcs asynchronously, the control system drives the T-plates at both ends to rotate at different angles. At this time, the T-plate group forms an asymmetrical bend, and the height difference between the two ends of the wind box 10 group gradually changes.

[0110] Thus, the arc-changing mechanism achieves high-precision attitude control and rapid response of the 10 wind boxes during the arc-changing process by alternately hinged multiple T-plates.

[0111] In addition, see Figure 3 and Figure 6 In this embodiment, the air box 10 has an air outlet surface, and a plurality of nozzles 101 are provided on the air outlet surface. The nozzles 101 can spray a fast airflow toward the glass 90 surface on the conveying roller 80.

[0112] Example 2

[0113] See Figure 7 and Figure 8Unlike Embodiment 1, this embodiment discloses a glass forming apparatus, which includes a roller conveyor assembly and the air grid assembly adjustment device from Embodiment 1. Specifically, the roller conveyor assembly includes a plurality of conveyor rollers 80 arranged at intervals along a conveying direction, and the two ends of the conveyor rollers 80 are respectively connected to a first arc-changing member 21 and a second arc-changing member 31. The first arc-changing mechanism 20 and the second arc-changing mechanism 30 are used to drive the roller conveyor assembly to change arc in the conveying direction during arc changing. Simultaneously, an air box 10 is provided between two adjacent conveyor rollers 80 along the conveying direction, and the air box 10 is used to deliver airflow to the conveying surface of the conveyor rollers 80.

[0114] Based on this structure, the glass forming equipment includes a frame 100, and a variable arc drive mechanism 110 is provided on the top of the frame 100. The variable arc drive mechanism 110 includes a first variable arc drive component and a second variable arc drive component. The first variable arc drive component and the second variable arc drive component respectively lift the first variable arc mechanism 20 and the second variable arc mechanism 30.

[0115] Both the first and second arc-changing drive components can include a motor, a drive sprocket, a chain, and a driven sprocket. The drive sprocket is mounted on the motor output shaft, and the driven sprockets are mounted at both ends of the arc-changing mechanism. The chain wraps around the drive sprocket and the driven sprockets at both ends of the arc-changing mechanism. Connecting blocks are spaced apart on the chain and are securely fixed to the chain by bolts or welding. The connecting blocks have connecting holes and are connected to the first arc-changing component 21 or the second arc-changing component 31 at both ends of the arc-changing mechanism via pins, allowing the linear motion of the chain to be transmitted to the arc-changing component.

[0116] When the motor drives the drive sprocket to rotate, the drive sprocket transmits power to the driven sprockets at both ends of the arc-changing mechanism via a chain. During transmission, the connecting blocks on the chain pull the first arc-changing element 21 or the second arc-changing element 31 at both ends of the arc-changing mechanism, causing the first arc-changing element 21 or the second arc-changing element 31 to be pulled upwards. Since the multiple first arc-changing elements 21 in the first arc-changing mechanism 20 are hinged to each other, the first arc-changing elements 21 at both ends transmit power to the adjacent first arc-changing elements 21 in sequence, causing the multiple first arc-changing elements 21 to gradually rotate around the hinge point, realizing the arc-changing action of the first arc-changing mechanism 20.

[0117] Before the arc-changing mechanism begins to change arc, the flat glass 90 to be processed is placed on the conveyor roller 80 at the starting end of the roller conveyor assembly. The conveyor roller 80 begins to rotate, driving the glass 90 forward smoothly along the conveying direction. During the conveying process, the glass 90 enters the heating zone for preheating, softening it. When the softened glass 90 is conveyed to the arc-changing zone, the control system issues a command, and the first arc-changing mechanism 20 and the second arc-changing mechanism 30 begin to work.

[0118] To produce curved glass 90 with the same radius of curvature at both ends, the first and second curved drive components work together. The motors in both drive components operate at the same speed and rotation angle, causing multiple first curved elements 21 and second curved elements 31 in the first and second curved mechanisms 20 and 30 to rotate synchronously by the same angle. Since the two ends of the conveyor roller 80 are connected to the first curved elements 21 and the second curved elements 31 respectively, the rotation of the curved elements drives the two ends of the conveyor roller 80 to rise or fall synchronously, forming a regular curved structure in the conveying direction. Simultaneously, the air box 10 in the air grid assembly adjustment device maintains a horizontal posture under the action of the first curved elements 21 and the second curved elements 31, and the air outlet surface of the air box 10 is adjusted to be parallel to the conveying surface of the conveyor roller 80 by the action of the actuating element 23. At this time, the air box 10 delivers a uniform airflow to the conveying surface of the conveyor roller 80, performing preliminary shaping and cooling of the glass 90 located on the curved conveyor roller 80.

[0119] If producing conical glass 90, the control system independently controls the motors of the first and second arc-changing drive components, causing the two motors to operate at different speeds and rotation angles. The first arc-changing mechanism 20 and the second arc-changing mechanism 30 perform asynchronous arc-changing, that is, the first arc-changing component 21 and the second arc-changing component 31 rotate at different rotation angles. This angular difference causes the two ends of the conveying roller 80 to be lifted to different heights, and the multiple conveying rollers 80 form a conical arc structure with different radii of curvature at both ends in the conveying direction. During this process, the bellows 10 also tilts under the drive of the arc-changing components, and its air outlet surface maintains a small angle with the conveying surface of the conveying roller 80.

[0120] In addition, according to a preset program, the wind box 10 will drive the first mounting base 222 and the second mounting base 322 to slide along the slide rail through the first driving member 60 and the second driving member 61 of the wind grid drive assembly, so that the wind box 10 as a whole moves closer to or further away from the conveying roller 80, in order to adjust the intensity and distance of the airflow and ensure that the glass 90 can be properly cooled and shaped in different curvature areas.

[0121] Therefore, the first arc-changing mechanism 20 and the second arc-changing mechanism 30, through asynchronous arc-changing, can precisely control the height changes at both ends of the conveying roller 80, thereby enabling the multiple conveying rollers 80 to form an arc structure that conforms to the shape requirements of the conical glass 90. This precise arc-changing control ensures that the glass 90 can obtain the required curvature change during the forming process, achieving accurate forming of the conical glass 90. At the same time, the bellows 10 in the air grid assembly adjustment device can adjust its posture, angle, and position in real time according to the action of the arc-changing mechanism. During the arc-changing process of the glass 90, the airflow delivered by the bellows 10 can apply uniform pressure to the surface of the glass 90, assisting the glass 90 in conforming to the shape of the conveying roller 80, further improving the accuracy and quality of the glass 90 forming, and avoiding problems such as inconsistent deformation and uneven surface of the glass 90.

[0122] In summary, the glass forming equipment of this embodiment can produce conventional curved glass 90 with the same radius of curvature at both ends by synchronous arc changing, and can also produce conical glass 90 by asynchronous arc changing. Furthermore, by adjusting the arc changing parameters and controlling the action of the wind box 10, the glass 90 can be uniformly subjected to cooling air, resulting in a better tempering effect.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
