Description

Technical Field

[0001] This utility model relates to the field of glass deep processing technology, and in particular to a variable arc device and a conical glass forming equipment. Background Technology

[0002] Currently, with the increasing demand for irregularly shaped glass from industries such as architectural decoration and automobile manufacturing, conical glass with different radii at both ends is experiencing a surge in market demand due to its unique appearance and performance advantages. While some low-precision conical glass is processed using methods like suspended tempering and mold forming, these methods lack a precise curvature control mechanism. Under gravity or during mold bonding, the glass struggles to achieve the ideal curvature, resulting in low bending accuracy in the finished product.

[0003] In the field of glass deep processing, rigid shaft roller conveyor bending and tempering equipment has become the mainstream equipment for glass bending and tempering due to its high efficiency and stability. In existing ordinary rigid shaft roller conveyor systems, the two ends of the forming roller are connected to the two side arc-changing rollers by a rotating connection. When the two side arc-changing rollers are pulled up synchronously with the same amplitude, the rigid shaft roller conveyor will form an arc-shaped trajectory with the same radius of curvature at both ends in the conveying direction. This working condition is suitable for producing conventional curved glass.

[0004] However, when producing conical glass, the process requires the two curved rollers on both sides to be pulled up with different curvatures to tilt the forming roller. But due to the existing structural design, since the distance between the two curved rollers is fixed, the forming roller inevitably experiences a length change along its axis during tilting. Without an effective compensation mechanism, a rigid constraint forms between the forming roller and the curved roller, making it difficult for the forming roller to tilt smoothly and hindering the unequal curvature operation of the curved roller. This structural defect directly limits the application range of existing rigid-shaft roller bending tempering equipment, enabling it to only perform glass bending tempering with a single curvature and failing to meet the processing requirements for conical glass. Utility Model Content

[0005] In order to overcome at least one of the defects mentioned above in the prior art, one of the objectives of this utility model is to provide a variable arc device, which can compensate for the length change of the roller assembly between the two variable arc components caused by the tilting of the forming roller through the telescopic movement of the telescopic roller, ensuring that the forming roller can tilt accurately, so that the roller assembly forms an arc with unequal curvature at both ends that meets the processing requirements of conical glass, thus avoiding the problem of low processing accuracy.

[0006] The second objective of this utility model is to provide a conical glass forming equipment, whose arc-changing device can compensate for the length change of the roller assembly between the two arc-changing components caused by the tilting of the forming roller through the telescopic movement of the telescopic roller.

[0041] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0042] Example 1

[0043] See Figures 1 to 3 This utility model discloses a variable arc device, which includes a roller conveyor assembly and a variable arc assembly. The roller conveyor assembly includes multiple roller components arranged at intervals along a conveying direction. (See reference...) Figure 1 The roller conveyor includes a forming roller 10 and a telescopic roller 11, and the forming roller 10 has a first end 101 and a second end 102, the first end 101 being hinged to the end of the telescopic roller 11.

[0044] The arc-changing assembly includes a first arc-changing element 20 and a second arc-changing element 30, which are respectively disposed on both sides of the multiple roller conveyor components. (See reference...) Figure 2 The first arc-changing component 20 is rotatably connected to the telescopic roller 11, and also slidably connected to the telescopic roller 11; the second arc-changing component 30 is hinged to the second end 102. Specifically, the first arc-changing component 20 and the second arc-changing component 30 are used to drive multiple roller components to change arc in the conveying direction during arc changing. (See reference...) Figure 2 as well as Figure 3 The telescopic roller 11 is used to slide relative to the first arc-changing member 20 when the forming roller 10 is in an inclined state.

[0045] Based on this structure, when using the arc-changing device of this utility model, the glass 60 that has been heated to a softened state is first received by the roller assembly, and then the first arc-changing component 20 and the second arc-changing component 30 perform arc-changing, and drive multiple roller components to perform arc-changing in the conveying direction.

[0046] See Figure 2 When the first arc-changing component 20 and the second arc-changing component 30 have not yet changed arcs, both arc-changing components are in the unfolded state. The two connection points on the same roller conveyor that are connected to the first arc-changing component 20 and the second arc-changing component 30 are at the same height. At this time, the forming roller 10 and the telescopic roller 11 are both in the horizontal state, and multiple forming rollers 10 are laid horizontally along the conveying direction.

[0047] When the first arc-changing component 20 and the second arc-changing component 30 simultaneously change arc, the two connection points on the same roller conveyor that are connected to the first arc-changing component 20 and the second arc-changing component 30 are simultaneously lifted to the same height during the arc-changing process. At this time, the single forming roller 10 and the telescopic roller 11 are still in a horizontal state, while the multiple horizontal forming rollers 10 have an arc-shaped structure in the conveying direction. Under the action of the multiple forming rollers 10, the softened glass 60 on the roller conveyor assembly is bent into an arc-shaped glass with the same radius of curvature at both ends.

[0048] See Figure 3 When the first arc-changing component 20 and the second arc-changing component 30 change arcs asynchronously, it should be noted that the asynchronous arc-changing component 20 and the second arc-changing component 30 means that the first arc-changing component 20 and the second arc-changing component 30 bend with different curvatures. At this time, the two connection points on the same roller conveyor that are connected to the first arc-changing component 20 and the second arc-changing component 30 are located at different heights. In order to adapt to the change in height at both ends, the first end 101 of the forming roller 10 rotates relative to the telescopic roller 11, and at the same time, the second end 102 of the forming roller 10 rotates relative to the second arc-changing component 30, so that the forming roller 10 gradually changes from a horizontal state to an inclined state, while the telescopic roller 11 remains in a horizontal state.

[0049] Since the distance between the first variable arc member 20 and the second variable arc member 30 on both sides of the roller conveyor remains constant, when the forming roller 10 rotates from a horizontal state relative to the first variable arc member 20 and the telescopic roller 11 to an inclined state, the forming roller 10 pulls the telescopic roller 11, causing the telescopic roller 11 to slide relative to the first variable arc member 20 and move closer to the forming roller 10, thereby adapting to the changes in the angle and position of the forming roller 10. At this time, the multiple inclined forming rollers 10 have an arc-shaped structure in the conveying direction, and this arc-shaped structure has different radii of curvature at both ends of the length of the forming roller 10. Under the force of the forming roller 10, the softened glass 60 on the forming roller 10 is bent into a conical arc-shaped glass 60 with different radii of curvature at both ends.

[0050] Thus, when the first arc-changing component 20 and the second arc-changing component 30 change arc synchronously, the forming roller 10 remains horizontal, and the multiple horizontal forming rollers 10 are arranged in an arc shape, which can bend the softened glass 60 into ordinary curved glass 60. However, when the first arc-changing component 20 and the second arc-changing component 30 change arc asynchronously, that is, when bending with different curvatures, the forming roller 10 changes from horizontal to inclined, and the multiple inclined forming rollers 10 form an arc structure with unequal curvatures at both ends in the conveying direction. At this time, the softened glass 60 can be bent into conical glass 60 with different radii at both ends.

[0051] Therefore, through the hinged engagement of the telescopic roller 11 and the forming roller 10, and the sliding engagement of the telescopic roller 11 relative to the first arc-changing component 20, the forming roller 10 can tilt during the arc-changing process, allowing its two ends to adapt to the different heights of the two arc-changing components. Simultaneously, the telescopic movement of the telescopic roller 11 can compensate for the length change of the roller path between the two arc-changing components caused by the tilting of the forming roller 10. The forming roller 10 can adaptively adjust its angle and position. In this way, the forming roller 10 with multiple roller path components can form an arc shape that meets the production requirements of the conical glass 60, reducing positional deviations and deformations of the glass 60 during processing, ensuring the accuracy of the bending curvature of the glass 60, and improving the quality of the glass 60 product.

[0052] Meanwhile, the arc-changing device of this utility model can adjust the arc state of multiple forming rollers 10 in the conveying direction by adjusting the arc curvature and arc degree of the first arc-changing component 20 and the second arc-changing component 30, thereby producing conical glass 60 of different specifications, or other irregularly shaped glass 60 with special arc requirements, and has high processing accuracy.

[0053] As an optional implementation, the roller conveyor assembly further includes a roller conveyor drive mechanism 15, which drives the forming roller 10 or the telescopic roller 11 to rotate around its own axis. The forming roller 10 and the telescopic roller 11 are connected in a transmission connection to ensure that they rotate synchronously.

[0054] Based on this structure, after starting the roller drive mechanism 15, if the roller drive mechanism 15 is connected to the forming roller 10, then its power is first transmitted to the forming roller 10. Since the forming roller 10 is connected to the telescopic roller 11, the forming roller 10 and the telescopic roller 11 will rotate synchronously and rotate around their respective axes.

[0055] During the arc-changing process, when the forming roller 10 is tilted, the hinge point between the forming roller 10 and the telescopic roller 11 allows the angle between the forming roller 10 and the telescopic roller 11 to change. At the same time, the structure of the forming roller 10 and the telescopic roller 11 connected by transmission can maintain the stability of power transmission and ensure that the forming roller 10 and the telescopic roller 11 rotate synchronously during the arc-changing process.

[0056] In addition, the roller drive mechanism 15 can also synchronously drive multiple roller components to rotate. Thus, when the arc-changing component drives the roller components to change arc, the roller drive mechanism 15 continuously drives multiple roller components to rotate, forming a continuous conveying surface, so that the glass 60 can be bent and formed simultaneously during the conveying process.

[0057] As an optional implementation, a first universal joint 40 is provided between the forming roller 10 and the telescopic roller 11. Specifically, the first universal joint 40 includes a cross shaft 41 and two universal joint forks 42, one of which is connected to the first end 101, and the other is connected to the end of the telescopic roller 11. The universal joint forks 42 are provided with rotating holes, and the four journals of the cross shaft 41 are rotatably engaged with the rotating holes on the two universal joint forks 42, so that the forming roller 10 and the telescopic roller 11 are hinged and connected by transmission between them.

[0058] Based on this structure, when the arc-changing assembly drives the roller conveyor to change its arc, if the first arc-changing component 20 and the second arc-changing component 30 do not move synchronously, the forming roller 10 will tilt relative to the telescopic roller 11. At this time, the cross shaft 41 of the first universal joint 40 allows the two universal joint forks 42 to rotate relative to each other in multiple planes through the rolling of the four journals in the rotating holes, thereby adapting to the angle change between the forming roller 10 and the telescopic roller 11.

[0059] Meanwhile, when the forming roller 10 rotates under the drive of the roller drive mechanism 15, the power of its rotation can be transmitted to the telescopic roller 11 via the transmission link composed of the cross shaft 41 and the universal joint fork 42, so that the forming roller 10 and the telescopic roller 11 rotate synchronously.

[0060] Therefore, the first universal joint 40, through the multi-plane rotation characteristics of the cross shaft 41, can maintain efficient power transmission even when the two shafts are at different angles, so that the arc changing device can ensure that the forming roller 10 and the telescopic roller 11 always rotate synchronously during the complex arc changing process, avoiding transmission failure caused by angle changes.

[0061] Meanwhile, during the arc-changing process, the angular adaptability of the first universal joint 40 can cooperate with the sliding movement of the telescopic roller 11. When the arc-changing assembly drives the forming roller 10 to tilt, the first universal joint 40 allows the forming roller 10 to rotate relative to the telescopic roller 11. At the same time, the telescopic roller 11 compensates for the axial displacement of the forming roller 10 caused by the angle change by sliding relative to the first arc-changing component 20, ensuring the structural stability of the entire roller conveyor during the arc-changing process.

[0062] As an optional implementation, the roller conveyor assembly further includes a connecting roller 12, which passes through and is rotatably connected to the second arc-changing member 30. One end of the connecting roller 12 is drive-connected to the roller conveyor drive mechanism 15, the other end of the connecting roller 12 is hinged to the second end 102, and the connecting roller 12 is drive-connected to the forming roller 10.

[0063] Based on this structure, after the roller drive mechanism 15 is activated, power is transmitted to the connecting roller 12. The connecting roller 12, acting as an intermediate transmission component, transmits torque to the second end 102 of the forming roller 10. When the arc-changing assembly is activated, the second arc-changing element 30 drives the connecting roller 12 to move synchronously. The rotational connection between the connecting roller 12 and the second arc-changing element 30 allows it to rotate around its own axis while following the movement of the arc-changing element. Furthermore, the hinge between the connecting roller 12 and the second end 102 of the forming roller 10 allows for relative angular changes between the two during the arc-changing process.

[0064] Therefore, the rotating connection structure between the connecting roller 12 and the second arc-changing component 30 ensures the synchronization of their movements during the arc-changing process. When the second arc-changing component 30 moves along a preset trajectory, the connecting roller 12 can provide stable power output without interfering with the arc-changing action.

[0065] Furthermore, the connecting roller 12, as an independent transmission module, facilitates the assembly and maintenance of the equipment. When it is necessary to replace the drive motor or repair the transmission system, the module can be quickly replaced simply by disassembling the connecting structures at both ends of the connecting roller 12.

[0066] As an optional implementation, a second universal joint 50 is provided between the forming roller 10 and the connecting roller 12. Specifically, the second universal joint 50 includes a cross shaft 41 and two universal joint forks 42, one of which is connected to the second end 102, and the other is connected to the end of the connecting roller 12. The universal joint forks 42 are provided with rotating holes, and the four journals of the cross shaft 41 are rotatably engaged with the rotating holes on the two universal joint forks 42, so that the forming roller 10 and the connecting roller 12 are hinged and connected by transmission.

[0067] Based on this structure, when the arc-changing assembly drives the roller conveyor to change its arc, if the first arc-changing component 20 and the second arc-changing component 30 do not move synchronously, the forming roller 10 will tilt relative to both the telescopic roller 11 and the connecting roller 12. At this time, the cross shaft 41 of the second universal joint 50 allows the two universal joint forks 42 to rotate relative to each other in multiple planes through the rolling of the four journals in the rotating holes, thereby adapting to the angle changes between the forming roller 10 and the connecting roller 12.

[0068] Meanwhile, when the connecting roller 12 rotates under the drive of the roller conveyor drive mechanism 15, the power of its rotation can be transmitted to the forming roller 10 via the transmission link composed of the cross shaft 41 and the universal joint fork 42, so that the forming roller 10 and the connecting roller 12 rotate synchronously.

[0069] Therefore, the second universal joint 50, through the multi-plane rotation characteristics of the cross shaft 41, can maintain efficient power transmission even when the two shafts are at different angles, so that the arc changing device can ensure that the forming roller 10 and the connecting roller 12 always rotate synchronously during the complex arc changing process, avoiding transmission failure caused by angle changes.

[0070] It should be noted that in this invention, the roller conveyor drive mechanism 15 can be a chain-driven roller conveyor drive mechanism 15 as in the prior art. Specifically, the chain-driven roller conveyor drive mechanism 15 includes a drive motor, a drive sprocket, a transmission chain, and a driven sprocket. A driven sprocket is fixedly mounted at one end of each roller conveyor component, and the driven sprocket is fixed to the roller conveyor component by a key connection or an expansion sleeve connection. In this invention, the driven sprocket is mounted at one end of the connecting roller 12, and the other end of the connecting roller 12 passes through the second arc-changing member 30 and is hinged to the forming roller 10.

[0071] In addition, the output shaft of the drive motor is connected to the drive sprocket, which is connected to the transmission chain. The chain forms a closed-loop transmission around the driven sprockets on multiple roller conveyors. When the drive motor is turned on, power is transmitted to the drive sprocket, which rotates and drives the transmission chain to rotate, thereby transmitting power to each roller conveyor and causing multiple roller conveyors to rotate synchronously.

[0072] In addition, the roller drive mechanism 15 can also be a gear-driven roller drive mechanism 15 or a synchronous belt-driven roller drive mechanism 15 as in the prior art.

[0073] As an optional implementation, a bearing assembly 43 is provided between the journal of the cross shaft 41 and the universal joint fork 42. For details, please refer to [link to relevant documentation]. Figure 2 The bearing assembly 43 includes a needle roller bearing 44 and a thrust bearing 45. The needle roller bearing 44 is installed between the outer periphery of the journal of the cross shaft 41 and the side wall of the rotating hole, while the thrust bearing 45 is installed between the end of the journal of the cross shaft 41 and the bottom wall of the rotating hole.

[0074] Based on this structure, when the roller conveyor changes arc, the forming roller 10 rotates and changes angle relative to the telescopic roller 11 and the connecting roller 12, respectively, causing the cross shaft 41 of the first universal joint 40 and the second universal joint 50 to move within the rotation hole of the universal joint fork 42. At this time, the needle roller bearing 44 plays a role, with its numerous tiny needles rolling between the outer circumference of the journal of the cross shaft 41 and the side wall of the rotation hole, allowing the cross shaft 41 to rotate flexibly in the rotation hole to adapt to different angle changes.

[0075] Meanwhile, due to the inclination of the forming roller 10 and the gravity of the glass 60, the forming roller 10 will generate radial force on the universal joint. The thrust bearing 45 is located between the end of the journal of the cross shaft 41 and the bottom wall of the rotating hole, and can withstand and disperse these radial forces, ensuring that the cross shaft 41 will not experience radial movement during rotation, thereby preventing the forming roller 10 from jumping when conveying the glass 60. In particular, since each of the four journals of the cross shaft 41 is equipped with a thrust bearing 45, these thrust bearings 45 can convert the radial force they receive into their own rotation, avoiding displacement of the journals, and thus accurately positioning the center point of the cross shaft 41.

[0076] Therefore, the universal joint can flexibly adapt to different angle changes between the forming roller 10, the connecting roller 12, and the telescopic roller 11. The forming roller 10 can tilt according to a predetermined trajectory to achieve precise arc changing. At the same time, since the universal joint can withstand large radial forces and the center point of the cross shaft 41 is accurately positioned, the stability of the universal joint structure is ensured, so that the power energy is stably transmitted from the connecting roller 12 and other components to the forming roller 10 during the arc changing process, maintaining the continuity and stability of the arc changing operation.

[0077] As an optional implementation method, see [link / reference]. Figure 4 The telescopic roller 11 passes through the first arc-changing member 20, and a first bushing 13 is provided on the outer periphery of the telescopic roller 11. The first bushing 13 is rotatably connected to the first arc-changing member 20. The telescopic roller 11 is provided with a first sliding part, and correspondingly, the first bushing 13 is provided with a second sliding part. The first sliding part and the second sliding part are mutually limited and engaged along the circumferential direction of the telescopic roller 11, and the first sliding part and the second sliding part are slidably engaged along the axial direction of the telescopic roller 11.

[0078] Based on this structure, when the roller conveyor drive mechanism 15 drives the roller conveyor to rotate, due to the circumferential limiting effect of the first sliding part and the second sliding part, the telescopic roller 11 will drive the first bushing 13 to rotate synchronously through the sliding fit structure. When the forming roller 10 tilts, the telescopic roller 11 will move relative to the first bushing 13 under the action of the forming roller 10. At this time, the first sliding part and the second sliding part slide relative to each other along the axial direction, allowing the telescopic roller 11 to extend or retract the first arc-shaped member 20.

[0079] Therefore, the axial sliding of the telescopic roller 11 can compensate for the length change of the roller conveyor when the forming roller 10 is tilted. By setting the first bushing 13, the dynamic arc change and continuous rotation of the roller conveyor can be synchronized, thereby improving production efficiency.

[0080] The first variable arc component 20 has a mounting hole, and the first bushing 13 passes through the mounting hole. The first bushing 13 and the first variable arc component 20 are fixed by a deep groove ball bearing 16, which restricts the radial runout of the telescopic roller 11. The telescopic roller 11 passes through the first bushing 13. The first bushing 13 and the telescopic roller 11 only transmit torque and do not bear axial force, which avoids wear or jamming of the mating surface due to axial load, thereby extending the service life of the mechanism.

[0081] As an optional implementation method, see [link / reference]. Figure 5 The connecting roller 12 is provided with a second bushing 14 on its outer periphery. Specifically, the second bushing 14 passes through the second arc-changing member 30 and is fixedly connected to the second arc-changing member 30. The connecting roller 12 is rotatably connected to the second bushing 14.

[0082] Based on this structure, when the roller drive mechanism 15 drives the connecting roller 12 to rotate, the connecting roller 12 will rotate relative to the second bushing 14 and transmit power to the forming roller 10 through the second universal joint 50 so that the forming roller 10 rotates synchronously.

[0083] The second arc-changing component 30 has a mounting hole, through which the second bushing 14 passes. The connecting roller 12 passes through the second bushing 14 and is assembled with the second bushing 14 via a deep groove ball bearing 16 or a cylindrical roller bearing to achieve relative rotation. Thus, during the arc-changing process, the connecting roller 12 changes its spatial angle with the second arc-changing component 30, but its own axial direction may deflect. At this time, the bearing allows the connecting roller 12 to rotate flexibly within the second bushing 14 to adapt to the angular deviation caused by the arc-changing process.

[0084] As an optional implementation method, see [link / reference]. Figure 7 The first arc-changing component 20 includes a plurality of first linkage plates 201 arranged along the conveying direction. Two adjacent first linkage plates 201 are hinged together, and the first linkage plates 201 are rotatably connected to and slidably connected to the telescopic roller 11. Similarly, the second arc-changing component 30 includes a plurality of second linkage plates 301 arranged along the conveying direction. Two adjacent second linkage plates 301 are hinged together, and the second linkage plates 301 are rotatably connected to the connecting roller 12.

[0085] Based on this structure, during assembly, two adjacent first linkage plates 201 or second linkage plates 301 can be connected by a hinge, and the linkage plates can rotate around the hinge axis. Then, mounting holes are provided on each of the first linkage plates 201 and second linkage plates 301. The telescopic roller 11 is rotatably mounted in the mounting hole of the first linkage plate 201 via a first bushing 13 and can slide relative to the first bushing 13. The connecting roller 12 is rotatably mounted in the mounting hole of the second linkage plate 301 via a second bushing 14, and the end of the connecting roller 12 extending outward from the second linkage plate 301 is connected to the driven sprocket of the roller conveyor drive mechanism 15.

[0086] When the arc is changed, taking the first arc changing component 20 as an example (the arc changing process of the second arc changing component 30 is similar), the external driving mechanism first pushes or pulls part of the first linkage plate 201, so that the adjacent linkage plates rotate relative to each other around the hinge axis, thereby changing the arc of the entire first arc changing component 20.

[0087] If the first arc-changing component 20 and the second arc-changing component 30 change arcs out of sync, causing the forming roller 10 to gradually tilt, the telescopic roller 11 will move relative to the first linkage plate 201 and approach the forming roller 10 to adapt to the length change of the roller path between the two arc-changing components caused by the tilt of the forming roller 10.

[0088] Therefore, through the independent arc changing of the first arc changing component 20 and the second arc changing component 30, and the length change compensation of the telescopic roller 11 when the forming roller 10 is tilted, the arc changing device of this utility model can adapt to the processing of glass 60 with different shapes and curvature requirements. In particular, for conical glass 60 with different radii at both ends, the first arc changing component 20 and the second arc changing component 30 can form the required arc trajectory through asynchronous arc changing.

[0089] As an optional implementation method, see [link / reference]. Figure 6 The arc-changing assembly also includes a first arc-changing drive 21 and a second arc-changing drive 31, wherein the first arc-changing drive 21 is used to drive the first arc-changing component 20 to change arc, and the second arc-changing drive 31 is used to drive the second arc-changing component 30 to change arc.

[0090] Based on this structure, during use, the first arc-changing drive component 21 can pull a portion of the linkage plate of the first arc-changing component 20, causing it to rotate around the hinge axis and changing the arc of the first arc-changing component 20. At the same time, the second arc-changing drive component 31 can synchronously or asynchronously drive the second arc-changing component 30. By adjusting the arc difference between the two sets of arc-changing components, the forming roller 10 can form a specific tilt angle to adapt to the different bending requirements at both ends of the glass 60.

[0091] Specifically, both the first arc-changing drive component 21 and the second arc-changing drive component 31 can include a drive motor and a chain drive component. The chain drive component includes a drive sprocket, a chain, and a driven sprocket. The drive sprocket is mounted on the output shaft of the drive motor, and the driven sprocket is mounted on the arc-changing component. The chain is wound around the two sprockets. When the motor rotates, the drive sprocket drives the chain, and the chain drives the driven sprocket, thereby driving the arc-changing component to move and achieve arc changing.

[0092] By independently controlling two drive components, the processing mode can be flexibly switched to meet the production needs of unconventional glass 60, such as conical, trapezoidal, and asymmetrical curved shapes. The drive components can precisely adjust the magnitude, direction, and speed of the driving force to ensure that the linkage plate of the curved component rotates at a set angle, avoiding glass 60 breakage due to excessive driving force or incomplete curved transformation due to insufficient driving force.

[0093] Example 2

[0094] Unlike Embodiment 1, this embodiment discloses a conical glass forming device, see reference. Figure 6 and Figure 7 The conical glass forming equipment includes a frame 70, a conveyor roller conveyor, and the arc-changing device described in Embodiment 1. Specifically, the frame 70 is equipped with a heating section and a forming section, and the conveyor roller conveyor runs through the heating section. The arc-changing device is located in the forming section, and the conveyor roller conveyor is connected to the roller conveyor assembly.

[0095] Based on this structure, when using the conical glass forming equipment of this embodiment, the flat glass 60 to be processed is first placed on the conveyor rollers. The conveyor rollers are started, driving the glass 60 to move along the rollers towards the heating section of the frame 70. In the heating section, the glass 60 is uniformly heated by the heating system equipped with the equipment (such as electric heating wire, radiant heating, etc.). As the temperature continues to rise, the glass 60 gradually softens, reaching a temperature suitable for bending and tempering. During this process, the conveyor rollers rotate continuously and stably, ensuring that the glass 60 can pass through the heating section at a uniform speed, ensuring that the glass 60 is heated evenly.

[0096] When the softened glass 60 enters the forming section of the frame 70 from the heating section, the arc-changing device begins to function. The first arc-changing drive component 21 and the second arc-changing drive component 31 in the arc-changing device are activated according to the preset processing parameters of the conical glass 60, respectively driving the first arc-changing component 20 and the second arc-changing component 30 to move. Adjacent first linkage plates 201 and second linkage plates 301 rotate relative to each other around the hinge axis, changing the curvature of the first arc-changing component 20 and the second arc-changing component 30.

[0097] In this system, the telescopic roller 11 is rotatably connected to and slidably fitted with the first arc-changing component 20, and the connecting roller 12 is rotatably connected to the second arc-changing component 30. When the arc of the arc-changing component changes, the telescopic roller 11 and the connecting roller 12 drive the roller conveyor assembly to arc synchronously. To process conical glass 60 with different radii at both ends, the first arc-changing component 20 and the second arc-changing component 30 arc asynchronously, causing the forming roller 10 to gradually tilt. The telescopic roller 11 moves relative to the first linkage plate 201 and approaches the forming roller 10 to adapt to the length change caused by the tilt of the forming roller 10. While the roller conveyor assembly forms a specific arc, the rotating roller conveyor continues to transport the softened glass 60, and the glass 60 gradually bends into a conical shape under the action of the roller conveyor assembly.

[0098] The glass 60, having completed its conical bending, continues to leave the forming section under the drive of the conveyor rollers and enters the subsequent cooling zone. In the cooling zone, the glass 60 is rapidly cooled and shaped using methods such as air cooling and water cooling, ultimately forming a finished conical glass 60 that meets the requirements.

[0099] Therefore, the conical glass forming equipment of this utility model integrates multiple processing steps such as glass preheating, arc forming, and cooling and shaping. Through the coordinated work of the frame 70, conveyor rollers, and arc-changing device, the automated production of conical glass 60 from flat glass 60 to finished product is realized. By adjusting the parameters of the arc-changing device, conical glass 60 of different specifications and with different curvature requirements can be processed. Whether it is conical glass 60 with a small difference in the radii at both ends or conical glass 60 with a large difference in radius and a complex shape, the processing requirements can be met by changing the arc-changing method and degree of the first arc-changing component 20 and the second arc-changing component 30.

[0100] The motion state of the forming roller 10 when the first arc-changing component 20 and the second arc-changing component 30 change arcs asynchronously, as well as the telescopic structure of the telescopic roller 11 and the adaptation motion process of the telescopic roller 11 and the forming roller 10, are described in detail in Embodiment 1, and will not be elaborated further here.

[0101] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. 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.
