Description

Technical Field

[0001] This utility model belongs to the field of curved glass forming technology, specifically relating to a curved glass arc-changing system and curved glass forming equipment with adjustable length. Background Technology

[0002] In order to produce curved glass of more sizes, current glass deep processing enterprises will purchase various specifications of hard shaft bending equipment. Among them, the equipment for producing large-size curved glass has a large footprint, high equipment investment cost, and high operating cost, but its utilization rate is low. The reasons are as follows: (1) If the large-size curved glass equipment is used for bending and forming small and medium-sized glass, its forming accuracy is poor and it is difficult to meet the quality requirements of small and medium-sized glass; (2) The curved glass arc system of the large-size curved glass equipment is long, and the time from when the glass comes out of the heating furnace to when it begins to bend and form is long, resulting in a large temperature drop in the glass and affecting the forming quality; (3) Generally, the central angle of the arc after the arc is changed by the arc device does not exceed 150°. If the central angle exceeds 150°, there will be two difficulties. One difficulty is the limitation of the structure of the hard shaft bending equipment itself, and the other difficulty is the excessive size. The central angle will cause the center of gravity of the curved device to shift, especially when it exceeds 180°. After the two ends of the curved device are pulled into place, they will buckle inward. This will cause the curved device to be unable to flatten after the glass is formed, thus making it impossible to produce glass sheets or to perform subsequent glass bending. This will seriously affect the continuity of glass bending. (4) The curved device of the large-size curved glass equipment is long and the minimum radius that can be bent is relatively large. It is difficult to form small-size, small-radius curved glass. For example, a 6-meter long curved glass equipment can only produce curved glass with a radius of more than 3.5 meters. Based on the above four reasons, the idle rate of large-size curved glass equipment in glass deep processing enterprises is high, which is a great waste for enterprises. Small-size curved glass equipment needs to be purchased separately to produce small-size, small-radius curved glass, which increases the production cost of enterprises.

[0003] Therefore, improving existing large-size curved glass equipment to overcome the above problems, thereby increasing equipment utilization and reducing costs for glass deep processing enterprises, is of great practical significance. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable-length curved glass system and curved glass forming equipment. By improving existing large-size curved glass equipment, the utilization rate of large-size curved glass equipment is increased, and the production cost of glass deep processing enterprises is reduced.

[0005] To achieve the above objectives, the first technical solution adopted by this utility model is: an adjustable-length curved glass arc-changing system, comprising a frame, an arc-changing device, a first arc-lifting mechanism, and a second arc-lifting mechanism. The first arc-lifting mechanism is connected to the inlet end of the arc-changing device, and the second arc-lifting mechanism is connected to the outlet end of the arc-changing device. Based on the arc length of the target curved glass, the arc-changing system is divided into a bending forming section and a forming candidate section by disassembling and assembling the arc-changing device. There is one bending forming section and one or two forming candidate sections. The first arc-lifting mechanism is connected to the inlet end of the bending forming section, and the second arc-lifting mechanism is connected to the outlet end of the bending forming section. The length of the bending forming section is adapted to the arc length of the target curved glass, and the first and second arc-lifting mechanisms work together to achieve the bending of the bending forming section.

[0006] Its beneficial effects are: by disassembling and assembling the arc-changing device, the arc-changing system is divided into a bending and forming section and a forming candidate section. The bending and forming section is used for bending and forming the glass, while the forming candidate section is used for conveying the glass or adjusting the length of the bending and forming section. This can adjust the effective length of the arc-changing system in the existing large-size glass bending equipment to participate in the glass bending and forming, so as to meet the bending and forming of smaller-size glass, thereby improving the utilization rate of large-size glass bending equipment and reducing the production cost of glass deep processing enterprises.

[0007] Furthermore, the arc-changing device includes an upper arc-changing device and a lower arc-changing device. The upper arc-changing device includes two opposing upper arc-changing mechanisms and an upper roller disposed between the two upper arc-changing mechanisms. The lower arc-changing device includes two opposing lower arc-changing mechanisms and a lower roller disposed between the two lower arc-changing mechanisms. The lower arc-changing mechanism includes a plurality of sequentially hinged lower arc-changing units, and at least two adjacent lower arc-changing units are detachably and rotatably connected.

[0008] Its beneficial effects are: to further clarify the composition of the arc-changing device, and that at least one part of the lower arc-changing device is detachable, thereby realizing the disassembly of the arc-changing system.

[0009] Furthermore, the arc-changing system also includes a horizontal displacement mechanism disposed above the arc-changing device, wherein the first arc-lifting mechanism and / or the second arc-lifting mechanism are movably disposed on the horizontal displacement mechanism.

[0010] Its beneficial effects are as follows: After the arc-changing system is disassembled, the length of the bending and forming section is shorter than the original arc-changing device. Therefore, a horizontal displacement mechanism is needed to translate the positions of the first and / or second arc-lifting mechanisms so that the distance between the first and second arc-lifting mechanisms can better match the length of the bending and forming section, thereby improving the accuracy of glass bending and forming. Furthermore, the movable arc-lifting mechanism can also be used during disassembly and assembly, reducing the labor intensity of disassembly and assembly operations and improving efficiency.

[0011] Furthermore, the second arc-lifting mechanism includes a plurality of second connectors, which are spaced apart along the glass conveying direction. During operation, the exit end of the bending forming section is connected to the second connector at its corresponding position.

[0012] Its beneficial effects are: multiple second connectors allow the second arc-lifting mechanism to have multiple hanging points, with each second connector corresponding to a hanging point at a specific location. After the arc-changing system is divided into a bending forming section and a forming candidate section along the glass conveying direction, the length of the bending forming section is less than that of the original arc-changing device. The second connector at the corresponding location can be selected to connect to the outlet end of the bending forming section, so that the distance between the first arc-lifting mechanism and the second arc-lifting mechanism can better match the length of the bending forming section, thereby improving the accuracy of glass bending forming.

[0013] Furthermore, the first arc-lifting mechanism includes a plurality of first connectors, which are spaced apart along the glass conveying direction. During operation, the inlet end of the bending forming section is connected to the first connector at its corresponding position.

[0014] Its beneficial effects are: multiple first connectors can make the first arc lifting mechanism have multiple hanging points, with each first connector corresponding to a hanging point at a certain position. When the arc changing system is split into a forming candidate section and a bending forming section along the glass conveying direction, the length of the bending forming section is less than the original arc changing device. The first connector at the corresponding position can be selected to connect with the entrance end of the bending forming section, so that the distance between the first arc lifting mechanism and the second arc lifting mechanism can better match the length of the bending forming section, thereby improving the accuracy of glass bending forming.

[0015] When the variable arc system is divided into a first forming candidate section, a bending forming section and a second forming candidate section along the glass conveying direction, the first and second connecting parts at corresponding positions are connected to the inlet and outlet ends of the bending forming section, respectively, so that the distance between the first and second arc lifting mechanisms can better match the length of the bending forming section, thereby improving the accuracy of glass bending forming.

[0016] Furthermore, the forming candidate section includes an upper forming candidate section and a lower forming candidate section, and the curved glass curvature system also includes a lifting mechanism, which is located above the upper forming candidate section and is used to lift the upper forming candidate section.

[0017] Its beneficial effects are: by lifting the upper forming candidate section as a whole, the distance between it and the lower forming candidate section can meet the requirements of glass conveying or disassembly and assembly operations.

[0018] Furthermore, the arc-changing system also includes an upper translation mechanism for horizontally moving the upper forming candidate section.

[0019] Its beneficial effect is that it enables the translation of the upper forming candidate section, so that the distance between it and the bending forming section meets the bending forming requirements.

[0020] Furthermore, the forming candidate section includes an upper forming candidate section and a lower forming candidate section, and the curved glass arc-changing system also includes a lower translation mechanism for horizontally moving the lower forming candidate section.

[0021] Its beneficial effect is that it enables the translation of the lower forming candidate section, so that the distance between it and the bending forming section meets the requirements of bending forming.

[0022] Furthermore, the arc-changing system also includes a guide rod, which is slidably connected to the upper arc-changing mechanism and is movably mounted on the frame.

[0023] Its beneficial effects are: the guide rod can provide guidance for the lifting and lowering of the upper arc mechanism, and after the arc system is disassembled, the length of the upper bending forming section 402 is reduced. Therefore, the guide rod can be reconnected to the upper arc mechanism corresponding to the upper bending forming section 402 by translation, so as to provide guidance for the lifting and lowering of the upper bending forming section 402.

[0024] Furthermore, the arc-changing system also includes a fixing component, which is detachably connected to the lower arc-changing mechanism.

[0025] Its beneficial effects are: a certain position of the lower arc-changing device can be fixedly connected to the frame through a fastener, and the height of the lower arc-changing mechanism at the fixed connection position cannot be changed, which can serve as the bending reference point of the lower arc-changing mechanism. After the lower arc-changing device is disassembled, the length of the lower bending forming section used for glass bending and forming is reduced, and the bending reference point also needs to be changed accordingly. Therefore, the fastener is a detachable connection to facilitate the change of the bending reference point.

[0026] Furthermore, it also includes an arc-lifting unit, which includes two arc-lifting plate groups and a transition roller disposed between the two arc-lifting plate groups. The arc-lifting unit is detachably disposed at the inlet end and / or outlet end of the lower arc-changing device. After the lower arc-changing device is disassembled into a lower bending forming section and a lower forming candidate section, the arc-lifting unit is detachably disposed at the inlet end and / or outlet end of the lower bending forming section. The inlet end of the lower bending forming section is connected to the first arc-lifting mechanism through the arc-lifting plate groups, and / or the outlet end of the lower bending forming section is connected to the second arc-lifting mechanism through the arc-lifting plate groups.

[0027] Its beneficial effects are: integrating the arc-lifting plate assembly and the transition rollers into a module, the transition rollers on the arc-lifting unit can reduce the distance between the lower bending forming section and the lower forming candidate section, ensuring that the glass can smoothly enter the lower forming candidate section after forming. When using a movable arc-lifting mechanism for disassembly and assembly, it is only necessary to disconnect the connection between the arc-lifting plate assembly and the lower arc-changing device, use the arc-lifting mechanism to move the entire arc-lifting unit to a new position, and reconnect the arc-lifting plate assembly to the lower bending forming section. There is no need to disconnect the connection between the arc-lifting mechanism and the arc-lifting plate assembly, simplifying the disassembly and assembly operation and reducing labor intensity.

[0028] Furthermore, the arc-changing system also includes a backup arc-lifting unit, which includes a backup arc-lifting plate assembly and a backup transition roller installed on the backup arc-lifting plate assembly. After the lower arc-changing device is disassembled into a lower bending forming section and a lower forming candidate section, the backup arc-lifting unit is installed at the inlet end and / or outlet end of the lower bending forming section. The inlet end of the lower bending forming section is connected to the first arc-lifting mechanism through the backup arc-lifting plate assembly, and / or the outlet end of the lower bending forming section is connected to the second arc-lifting mechanism through the backup arc-lifting plate assembly.

[0029] Its beneficial effect is that the spare arc-raising unit has a similar function to the arc-raising unit. However, in this embodiment, it is not necessary to install and remove the arc-raising unit from the lower arc-changing device. Instead, the spare arc-raising unit can be installed at the required position, which can save the step of disassembling the arc-raising unit.

[0030] The present invention also proposes a second technical solution: a glass bending forming equipment, including an upper plate, a heating furnace, a bending forming device and an unloading device, wherein the bending forming device includes a glass bending arc-changing system that does not use a spare arc-raising unit.

[0031] Its beneficial effects are: it provides the application of the curved glass arc-changing system described above, and the arc-raising unit is installed on the lower arc-changing device.

[0032] This utility model also proposes a third technical solution: a glass bending forming equipment, including an upper plate, a heating furnace, a bending forming device, and an unloading device. The bending forming device includes a glass bending arc-changing system using a spare arc-lifting unit. The outlet end of the heating furnace is provided with an adjustable sheet-ejecting roller unit, and / or the inlet end of the unloading device is provided with an adjustable sheet-receiving roller unit. The adjustable sheet-ejecting roller unit and the adjustable sheet-receiving roller unit provide the necessary space for the lower bending forming section to be equipped with a spare arc-lifting unit by adjusting their own length or posture.

[0033] Its beneficial effects are: it provides an application of curved glass curvature system using a spare lifting unit. Due to the addition of the spare lifting unit, the total length of the system increases. Therefore, an adjustable roller unit needs to be used on the side with increased length. By extending or flipping, the effect of the increased length on the upper and / or lower sheet can be eliminated.

[0034] The beneficial effects of this utility model are as follows: This utility model divides the arc-changing system into a bending and forming section and a forming candidate section by disassembling and assembling the arc-changing device. The bending and forming section is used for bending and forming the glass, while the forming candidate section is used for conveying the glass or adjusting the length of the bending and forming section. In this way, the effective length of the arc-changing system participating in the bending and forming of the glass in the existing large-size glass bending equipment can be adjusted to meet the bending and forming of smaller-size glass, thereby improving the utilization rate of large-size glass bending equipment and reducing the production cost of glass deep processing enterprises.

Detailed Implementation

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention in any way.

[0037] Example 1: As shown in the figure, an adjustable-length curved glass system includes a frame 7, a curved glass device 1, a first lifting mechanism 2, and a second lifting mechanism 3. The curved glass device 1 includes an upper curved glass device and a lower curved glass device. The upper curved glass device includes two opposing upper curved glass mechanisms and an upper roller disposed between the two upper curved glass mechanisms. The lower curved glass device includes two opposing lower curved glass mechanisms and a lower roller disposed between the two lower curved glass mechanisms. Both the upper roller and the lower roller are rigid shaft rollers. The first lifting mechanism 2 is connected to the inlet end of the curved glass device 1, and the second lifting mechanism 3 is connected to the outlet end of the curved glass device 1. By lifting both ends of the curved glass device 1 through the first lifting mechanism 2 and the second lifting mechanism 3, the curved glass device 1 is bent into an arc, thereby driving multiple rigid shaft rollers to fit into a shaped curved surface that matches the shape of the target curved glass surface. The lower arc-changing mechanism is formed by sequentially hinged multiple lower arc-changing units 101, each of which is a T-shaped chain plate 105 or a Y-shaped chain plate; the upper arc-changing mechanism is formed by sequentially hinged multiple upper arc-changing units. The main structures and connection methods of the upper and lower arc-changing mechanisms are mature designs in this field and will not be described in detail here.

[0038] The arc-changing device 1 is detachable in length. Based on the arc length of the target curved glass, the arc-changing system can be divided into a bending forming section 4 and a forming candidate section 5 by disassembling and assembling the arc-changing device 1. There can be one bending forming section 4 and one or two forming candidate sections 5. After disassembly and assembly, the first arc-lifting mechanism 2 connects to the inlet end of the bending forming section 4, and the second arc-lifting mechanism 3 connects to the outlet end of the bending forming section 4. The length of the bending forming section 4 is adapted to the arc length of the target curved glass. The first arc-lifting mechanism 2 and the second arc-lifting mechanism 3 work together to achieve the bending of the bending forming section 4. This invention, by disassembling and assembling the arc-changing system into a bending forming section 4 and a forming candidate section 5, allows the bending forming section 4 to be used for glass bending, while the forming candidate section 5 cannot be used for glass bending but only for glass conveying or adjusting the length of the bending forming section 4. This adjusts the effective length of the arc-changing system in existing large-size glass bending equipment to accommodate the bending of smaller-size glass, thereby increasing the utilization rate of large-size glass bending equipment and reducing the production costs of glass deep-processing enterprises.

[0039] This utility model's curved glass system uses a rigid shaft roller, falling under the category of rigid shaft bending. The phrase "one or two forming candidate sections 5" is determined by whether the forming candidate sections 5 are located on one or both sides of the bending forming section 4. When all forming candidate sections 5 are located on the same side of the bending forming section 4, the forming candidate sections 5 constitute one section. Even if this section includes multiple shorter candidate sections, it is still considered "one forming candidate section 5." When the forming candidate sections 5 are located on the front and rear sides of the bending forming section 4 respectively, it constitutes "two forming candidate sections 5."

[0040] It should be noted that the disassembly and assembly of the arc-changing system is mainly achieved through the disassembly and assembly of the arc-changing device 1 in the arc-changing system. Therefore, the "total length of the arc-changing system" can be replaced by the total length of the arc-changing device 1 after it is flattened. The bending forming section 4 and the forming candidate section 5 of the arc-changing system are also the two sections after the arc-changing device 1 is split.

[0041] In this invention, the bending forming section 4 is used for bending and forming glass. The forming candidate section 5 can be used only to adjust the length of the bending forming section 4, for example, by lengthening the bending forming section 4, or to receive the portion removed after the length of the bending forming section 4 is reduced. After the glass is bent, the curved glass can be unloaded through an independent sheet-receiving mechanism. The forming candidate section 5 can also be used for conveying the glass before and / or after forming. For example, after the glass is bent, it can pass directly through the forming candidate section 5 for unloading. This setup is more efficient and is of great significance for ensuring production continuity and efficiency. The forming candidate section 5 can also be used partly for adjusting the length of the bending forming section 4 and partly for conveying the glass before and / or after forming. This invention disassembles the variable arc system into a bending and forming section 4 and a forming candidate section 5. The bending and forming section 4 is used for bending and forming the glass, while the forming candidate section 5 is not used for bending and forming the glass but only for conveying the glass or adjusting the length of the bending and forming section 4. This allows for adjusting the effective length of the variable arc system involved in glass bending and forming in existing large-size glass bending equipment, thus meeting the bending and forming needs of smaller-size glass. This improves the utilization rate of large-size glass bending equipment and reduces the production costs of glass deep-processing enterprises. Furthermore, in the design concept of this invention, only one functional section of the variable arc system is used for glass bending and forming before and after disassembly and assembly. Therefore, the number of mechanisms such as the arc-lifting mechanism and guide rod 6 in the corresponding variable arc system can remain consistent with the original forming equipment. There is no need to add new arc-lifting mechanisms and guide rods 6; the design concept of this invention can be achieved simply by improving the existing large-size glass bending equipment. This reduces equipment costs, alleviates the burden on glass deep-processing enterprises, and also reduces the time required for disassembly and assembly operations, thus reducing labor intensity.

[0042] Based on the above description, Figure 1-3 Simplified diagrams of the curved glass arc-changing system described in this utility model before and after disassembly and assembly are given respectively. Figure 1 In the process, the arc-changing system is disassembled and assembled along the glass conveying direction into a bending forming section 4 and a forming candidate section 5; Figure 2 In the process, the arc-changing system is disassembled and assembled along the glass conveying direction into a forming candidate section 5 and a bending forming section 4; Figure 3 In this process, the arc-changing system is disassembled and assembled along the glass conveying direction into a forming candidate section 5, a bending forming section 4, and another forming candidate section 5. Let the total length of the arc-changing system be L, and the length of the bending forming section 4 be L. A The total length of the forming candidate section 5 is L B Then L > L A >S, L>L B >0.

[0043] Example 2 Based on Embodiment 1, further, at least two adjacent lower arc changing units 101 in the lower arc changing mechanism are detachably rotatably connected.

[0044] Specifically, such as Figure 4 As shown, adjacent lower arc-changing units 101 that are detachably and rotatably connected can form a split point at the rotatable connection. The split points of the two lower arc-changing mechanisms are set correspondingly, that is, the positions of the split points are consistent in the length direction of the two lower arc-changing mechanisms. At the split point, the complete lower arc-changing device can be split into two segments, one as the lower bending forming segment 401 and the other as the lower forming candidate segment 503. Of course, the lower bending forming segment 401 and the lower forming candidate segment 503 can also be reconnected at this position to form a complete lower arc-changing device. Similarly, the same applies to the upper arc-changing device, which is disassembled into an upper bending forming segment 402 and an upper forming candidate segment 504.

[0045] Furthermore, for the lower arc-changing device, all lower arc-changing units 101 in each lower arc-changing mechanism can be connected by a detachable rotatable connection. When disassembly is required, the position to be split is determined according to the arc length and radius of the target curved glass. Alternatively, in each lower arc-changing mechanism, some arc-changing units are connected by a detachable rotatable connection, and the splitting points formed by the detachable rotatable connection are evenly spaced along the length of the lower arc-changing mechanism, or concentrated on one side of the lower arc-changing mechanism. Similarly, the upper arc-changing device can also be configured in this way, and the splitting positions on the upper and lower arc-changing devices correspond vertically.

[0046] In the prior art, the lower arc-changing mechanism is composed of multiple lower arc-changing units 101 connected in sequence by hinges. Each lower arc-changing unit 101 generally includes one T-shaped chain plate 105 or two T-shaped chain plates 105 with their surfaces facing each other. Hinge holes are provided at opposite ends of the upper part of each T-shaped chain plate 105. Adjacent lower arc-changing units 101 are hinged to the same connecting shaft through these hinge holes, thus achieving hinge connection between the lower arc-changing units 101. The connecting shaft is connected to a rigid shaft roller. Simultaneously, for precise control of the lower arc-changing mechanism's bending into an arc shape, a connecting rod 106 is also connected between adjacent lower arc-changing units 101. The two ends of the connecting rod 106 are connected to two adjacent lower arc-changing units 101, respectively. Specifically, each lower arc-changing unit 101 has a fixed shaft and a movable shaft for connecting the connecting rod 106. The movable shaft can move up and down within the arc-changing unit, while the fixed shaft remains stationary. The fixed end of the connecting rod 106 is connected to the fixed shaft, and the movable end of the connecting rod 106 is connected to the movable shaft. The existing lower arc-changing mechanism was not designed with disassembly and assembly requirements in mind, which means that the existing lower arc-changing mechanism cannot be disassembled and assembled.

[0047] Therefore, this utility model specifically provides a detachable and rotatable connection structure for two adjacent lower arc-changing units 101, such as... Figure 7As shown, the T-shaped chain plate 105 of one of the two adjacent lower arc-changing units 101 is an assembled chain plate. The assembled chain plate includes a chain plate body 102 and a quick-release chain 104. An arc-shaped groove 103 is provided on one end of the chain plate body 102 for hinge connection with the other lower arc-changing unit 101. The quick-release chain 104 is located at the hinge position of the two lower arc-changing units 101 and cooperates with the arc-shaped groove 103 to form the hinge hole. Alternatively, the quick-release chain 104 may have a complete hinge hole, in which case the arc-shaped groove 103 is not required on the chain plate body 102. The two lower arc-changing units 101 can be disconnected or connected at the hinge position by assembling and disassembling the quick-release chain 104. The fixed end of the connecting rod 106 is connected to the lower arc-changing unit 101 via a detachable pin 107. The corresponding lower arc-changing unit 101 and connecting rod 106 can be disconnected or connected by assembling and disassembling the detachable pin 107. Therefore, the two lower arc-changing units 101 can be quickly disconnected or connected by assembling and disassembling the quick-release chain 104 and the detachable pin 107. Furthermore, in other embodiments, each lower arc-changing mechanism has multiple splitting points, allowing for the selection of appropriate positions for splitting based on the target arc length and radius of the glass to be processed, making the splitting of the lower arc-changing mechanism more flexible and applicable to a wider range of situations.

[0048] In another embodiment, the detachable and rotatable connection structure of two adjacent lower arc-changing units 101 is as follows: Figure 8 As shown, the T-shaped chain plate 105 of one of the two adjacent lower arc-changing units 101 is an assembled chain plate. The assembled chain plate includes a chain plate body 102 and a quick-release chain 104. The quick-release chain 104 is located at the hinge position of the two lower arc-changing units 101. The two lower arc-changing units 101 can be disconnected or connected at the hinge position by disassembling and assembling the quick-release chain 104. The connecting rod 106 adopts a disconnectable connecting rod 108 with a detachable middle section. The connecting rod 106 between the two lower arc-changing units 101 can be disconnected by disconnecting and connecting the disconnectable connecting rod 108. Therefore, the two lower arc-changing units 101 can be quickly disconnected or connected by disassembling and assembling the quick-release chain 104 and the disconnectable connecting rod 108.

[0049] In the lower arc-changing device, each lower arc-changing mechanism is equipped with the aforementioned detachable and rotatable connection structure, and its position is consistent along the length direction of the two lower arc-changing mechanisms. This arrangement allows for rapid adjustment of the effective length involved in glass bending and forming within the lower arc-changing device. Furthermore, even when the connection between two adjacent lower arc-changing units 101 is broken, the overall structure of the lower arc-changing mechanism remains unchanged; the lower bending and forming section 401 can be directly used for glass bending and forming, and the lower forming candidate section 503 can be directly used for glass conveying.

[0050] The existing upper arc-changing mechanism is relatively easy to disassemble and assemble, so its structure will not be described in detail here.

[0051] Furthermore, after the arc-changing device 1 is disassembled into the bending forming section 4 and the forming candidate section 5, the bending forming section 4 needs to be lifted into an arc. Therefore, the first arc-lifting mechanism 2 and / or the second arc-lifting mechanism 3 need to be connected to the splitting position of the bending forming section 4. Considering that the length of the bending forming section 4 is less than the total length of the arc-changing device 1, and the splitting position has a large positional change compared to the end of the arc-changing device 1, the following structure can be used to connect the splitting position with the corresponding arc-lifting mechanism.

[0052] Method 1: A horizontal displacement mechanism is provided on the frame 7 above the arc-changing device 1. The first arc-lifting mechanism 2 and / or the second arc-lifting mechanism 3 are movably mounted on the horizontal displacement mechanism. The horizontal displacement mechanism can adopt a linear motion module commonly used in the prior art, such as a lead screw module, a slide rail slider module, a gear rack module, a linear motor module, a synchronous belt module, etc. After the arc-changing system is disassembled, the length of the bending forming section 4 is less than that of the original arc-changing device 1. Therefore, it is necessary to set up a horizontal displacement mechanism to translate the position of the first arc-lifting mechanism 2 and / or the second arc-lifting mechanism 3 so that the distance between the first arc-lifting mechanism 2 and the second arc-lifting mechanism 3 can better match the length of the bending forming section 4, thereby improving the accuracy of glass bending forming. Furthermore, the movable arc-lifting mechanism can also be used in the disassembly and assembly process. For example, the movable first arc-lifting mechanism 2 and the second arc-lifting mechanism 3 can be used to drive the arc-lifting unit 8 to move, thereby reducing the labor intensity of disassembly and assembly operations and improving disassembly and assembly efficiency.

[0053] (1) When the arc-changing system is disassembled into a bending forming section 4 and a forming candidate section 5 along the glass conveying direction, the second arc-lifting mechanism 3 needs to be moved above the outlet end of the bending forming section 4 to connect the second arc-lifting mechanism 3 with the outlet end of the bending forming section 4. For details, please refer to Figure 1 As shown. For more details, please refer to... Figure 4 As shown, the two ends of the lower bending forming section 401 are connected to the first lower lifting arc mechanism 201 and the second lower lifting arc mechanism 301, respectively, and the two ends of the upper bending forming section 402 are connected to the first upper lifting arc mechanism 202 and the second upper lifting arc mechanism 302, respectively.

[0054] (2) When the arc-changing system is disassembled and assembled into a forming candidate section 5 and a bending forming section 4 along the glass conveying direction, it is necessary to move the first arc-lifting mechanism 2 above the entrance end of the bending forming section 4 to connect the first arc-lifting mechanism 2 with the entrance end of the bending forming section 4. For details, please refer to Figure 2 As shown. For more details, please refer to... Figure 5As shown, the two ends of the lower bending forming section 401 are connected to the first lower lifting arc mechanism 201 and the second lower lifting arc mechanism 301, respectively, and the two ends of the upper bending forming section 402 are connected to the first upper lifting arc mechanism 202 and the second upper lifting arc mechanism 302, respectively.

[0055] (3) When the arc-changing system is disassembled and assembled into the first forming candidate section 501, the bending forming section 4, and the second forming candidate section 502 along the glass conveying direction, it is necessary to move the first arc-lifting mechanism 2 to connect with the inlet end of the bending forming section 4 above the inlet end of the bending forming section 4, and move the second arc-lifting mechanism 3 to connect with the outlet end of the bending forming section 4 above the outlet end of the bending forming section 4. For details, please refer to Figure 3 As shown. For more details, please refer to... Figure 6 As shown, the two ends of the lower bending forming section 401 are connected to the first lower lifting arc mechanism 201 and the second lower lifting arc mechanism 301, respectively, and the two ends of the upper bending forming section 402 are connected to the first upper lifting arc mechanism 202 and the second upper lifting arc mechanism 302, respectively. The first upper lifting arc mechanism 202 and the second upper lifting arc mechanism 302 are used for the variable arc bending or lifting of the upper bending forming section 402.

[0056] Method Two: Based on Method One, the difference is that the second lifting mechanism 3 includes multiple second connecting members, which are spaced apart along the glass conveying direction. Replacing the movable second lifting mechanism 3 in Method One with multiple spaced-apart second connecting members along the glass conveying direction allows for better matching of the distance between the first lifting mechanism 2 and the second lifting mechanism 3 with the length of the bending forming section 4, improving the accuracy of glass bending forming. Furthermore, only the existing second lifting mechanism 3 needs modification; no additional second lifting mechanism 3 is required, thus reducing the labor intensity of disassembly and assembly operations and improving efficiency.

[0057] When the arc-changing system is disassembled into a bending forming section 4 and a forming candidate section 5 along the glass conveying direction, the outlet end of the bending forming section 4 is connected to the second connecting member at its corresponding position, and the bending forming section 4 is curved under the combined action of the first arc-lifting mechanism 2 and the second connecting member.

[0058] Method 3: Based on Method 1 or Method 2, the difference is that the first arc lifting mechanism 2 includes multiple first connecting members, which are spaced apart along the glass conveying direction.

[0059] When the curved glass system is disassembled into a forming candidate section 5 and a bending forming section 4 along the glass conveying direction, the inlet end of the bending forming section 4 is connected to the first connecting member at its corresponding position. The bending forming section 4 is curved under the combined action of the first connecting member and the second lifting mechanism 3, or the bending forming section 4 is curved under the combined action of the first connecting member and the second connecting member. Replacing the movable first lifting mechanism 2 in method one with multiple first connecting members spaced apart along the glass conveying direction also allows the distance between the first lifting mechanism 2 and the second lifting mechanism 3 to better match the length of the bending forming section 4, improving the accuracy of glass bending forming. Furthermore, only the original first lifting mechanism 2 needs improvement; there is no need to add an additional first lifting mechanism 2, thereby reducing the labor intensity of disassembly and assembly operations and improving disassembly and assembly efficiency.

[0060] It is understandable that not only does the first arc-lifting mechanism 2 include multiple first connecting parts, but the second arc-lifting mechanism 3 also includes multiple second connecting parts. Thus, when the arc-changing system is disassembled and assembled along the glass conveying direction into the first forming candidate section 501, the bending forming section 4, and the second forming candidate section 502, the inlet end of the bending forming section 4 connects to the first connecting part at its corresponding position, and the outlet end of the bending forming section 4 connects to the second connecting part at its corresponding position. The first and second connecting parts include liftable chains. Replacing the movable first arc-lifting mechanism 2 and the second arc-lifting mechanism 3 in Method 1 with multiple first and second connecting parts spaced apart along the glass conveying direction also allows the distance between the first arc-lifting mechanism 2 and the second arc-lifting mechanism 3 to better match the length of the bending forming section 4, improving the accuracy of glass bending forming. Furthermore, only the original first arc-lifting mechanism 2 and the second arc-lifting mechanism 3 need to be improved; there is no need to install additional first arc-lifting mechanisms 2 and 3, thereby reducing the labor intensity of disassembly and assembly operations and improving disassembly and assembly efficiency.

[0061] Example 3 like Figure 4 As shown, based on Embodiment 1 or 2, the molding candidate section 5 in this embodiment includes an upper molding candidate section 504 and a lower molding candidate section 503.

[0062] Furthermore, a lifting mechanism 10 is provided on the upper part of the frame 7. The lifting mechanism 10 is located above the upper forming candidate section 504 and is used to lift the upper forming candidate section 504 so that the vertical distance between it and the lower forming candidate section 503 meets the height requirements for glass passage or the height requirements for disassembly and assembly operations. For example, it meets the height requirements for conveying glass before and / or after forming, or the height requirements required for the arc lifting mechanism to move the arc lifting unit 8. The lifting mechanism 10 can adopt common lifting mechanisms in the prior art, such as lifting platforms, cylinders, motor chains, etc.

[0063] Furthermore, the upper part of the frame 7 is also equipped with an upper translation mechanism, and the lifting mechanism 10 is connected to the upper translation mechanism, which drives the upper forming candidate section 504 to move horizontally relative to the upper bending forming section 402 in the glass conveying direction. This ensures that the horizontal distance between the upper forming candidate section 504 and the upper bending forming section 402 is sufficient to allow the upper bending forming section 402 to bend without interfering with its bending. The upper translation mechanism can adopt a linear motion module commonly used in the prior art, such as a lead screw module, a slide rail slider module, a gear rack module, a linear motor module, a synchronous belt module, etc.

[0064] Furthermore, the lower part of the frame 7 is also provided with a lower translation mechanism, which is connected to the lower forming candidate section 503. This mechanism drives the lower forming candidate section 503 to move horizontally relative to the lower bending forming section 401 in the glass conveying direction. This ensures that the horizontal distance between the lower forming candidate section 503 and the lower bending forming section 401 is sufficient to allow the lower bending forming section 401 to bend without interfering with its bending. It also provides installation space for the arc-raising unit 8 or a spare arc-raising unit. The lower translation mechanism includes a moving component and a connecting component. The connecting component connects to the lower forming candidate section 503 and may include connecting parts such as sleeves and forks, as well as connecting drive components such as motors, cylinders, and hydraulic cylinders. The connection position of the connecting part can be any position on the lower forming candidate section 503; preferably, it connects to the two lower arc-changing mechanisms within the lower forming candidate section 503. The moving component can be a linear motion module commonly used in the prior art, such as a lead screw module, a slide rail slider module, a gear rack module, a linear motor module, or a synchronous belt module.

[0065] Example 4 like Figure 4As shown, based on the above embodiment, the curved glass arc-changing system also includes a guide rod 6. The guide rod 6 is slidably connected to the upper arc-changing mechanism. The guide rod 6 is movably mounted on the frame 7. The guide rod 6 provides a bending reference point for the bending of the upper arc-changing mechanism, and thus provides a bending reference point for the upper arc-changing device. The upper arc-changing mechanism can move up and down along the guide rod 6 at the position where it is slidably connected to the guide rod 6. Preferably, the guide rod 6 is connected at the center position along the length direction of the upper arc-changing device. When the arc-changing system is disassembled and assembled into a bending forming section 4 and a forming candidate section 5 along the glass conveying direction, or into a forming candidate section 5 and a bending forming section 4 along the glass conveying direction, the guide rod 6 needs to be moved horizontally to slidably connect with the center position along the length direction of the upper arc-changing mechanism corresponding to the disassembled upper bending forming section 402. When the arc-changing system is disassembled and assembled into a first forming candidate section 501, a bending forming section 4, and a second forming candidate section 502 along the glass conveying direction, since the bending forming section 4 is still in the middle position, the bending reference point of the upper arc-changing device may remain unchanged, so it is not necessary to move the guide rod 6. Those skilled in the art will understand from this invention that the guide rod 6 is not necessarily located at the center of the upper arc-changing mechanism along its length. In some special cases, such as when producing unequal arc glass, it may not be located at the center of the upper arc-changing device or the upper bending forming section 402 along its length on the corresponding upper arc-changing mechanism. Those skilled in the art will also understand from this invention that the upper arc-changing device includes two upper arc-changing mechanisms, which are located on both sides of the glass conveying direction. Therefore, there are also two guide rods 6, which are slidably connected to the two upper arc-changing mechanisms on both sides of the glass conveying direction. The guide rod 6 can be connected to the frame 7 using a linear motion module to achieve mobility. Commonly used linear motion modules in the prior art include lead screw modules, slide rail slider modules, gear rack modules, linear motor modules, and synchronous belt modules.

[0066] In other embodiments, the curved glass curvature system also includes a fixing member 9, which is detachably connected to the lower curvature mechanism. The detachable connection method can be threaded connection, pin connection, or snap-fit. Each lower curvature mechanism has a corresponding fixing member 9. The lower curvature mechanism can be fixedly connected to the frame 7 via the fixing member 9. The height of the lower curvature mechanism at the fixed connection position cannot be changed and can serve as the bending reference point for the lower curvature mechanism, and thus as the bending reference point for the lower curvature device. Preferably, the fixing member 9 is located at the center of the lower curvature mechanism along its length in the lower curvature device, achieving a fixed connection between the middle of the lower curvature mechanism and the frame 7, facilitating the lifting of both ends of the lower curvature device into an arc. When the arc-changing system is disassembled and assembled into bending forming section 4 and forming candidate section 5 along the glass conveying direction, or into forming candidate section 5 and bending forming section 4 along the glass conveying direction, the installation position of the fixing member 9 needs to be adjusted according to the center position of the lower bending forming section 401 along its length direction to ensure that the center position of the lower arc-changing mechanism corresponding to the lower bending forming section 401 along its length direction can be fixedly connected to the frame 7. When the arc-changing system is disassembled and assembled into the first forming candidate section 501, bending forming section 4 and second forming candidate section 502 along the glass conveying direction, since the bending forming section 4 is still in the middle position, the bending reference point of the lower arc-changing device may not change, so it is not necessary to disassemble and adjust the position of the fixing member 9. Those skilled in the art can understand from this utility model that the fixing member 9 is not necessarily located at the center of the lower arc-changing mechanism along its length direction in the lower arc-changing device. In some special cases, such as when making unequal arc glass, it may not be set at the center of the lower arc-changing device or the lower bending forming section 401 along its length direction.

[0067] Example 5 Based on the above embodiments, the curved glass curvature system further includes an arc-raising unit 8. For example... Figure 9 As shown, the arc-raising unit 8 includes two arc-raising plate groups 801 and a transition roller 802 installed between the two arc-raising plate groups 801. The arc-raising unit 8 is detachably installed at the inlet end and / or outlet end of the lower arc-changing device via the arc-raising plate groups 801. After the arc-changing system is disassembled into a bending forming section 4 and a forming candidate section 5, the arc-raising unit 8 is detachably installed at the inlet end and / or outlet end of the lower bending forming section 401. The inlet end of the lower bending forming section 401 is connected to the first arc-raising mechanism 2 via the arc-raising plate groups 801, and / or the outlet end of the lower bending forming section 401 is connected to the second arc-raising mechanism 3 via the arc-raising plate groups 801.

[0068] Specifically, based on the distribution of the lower bending forming section 401 and the lower forming candidate section 503 after the lower arc changing device is disassembled and assembled, the arc lifting unit 8 has the following different configuration methods.

[0069] (1) When the lower arc-changing device needs to be disassembled into a lower bending forming section 401 and a lower forming candidate section 503 along the glass conveying direction, the arc-lifting unit 8 is set at the outlet end of the lower arc-changing device. After the lower arc-changing device is disassembled, the arc-lifting unit 8 at the outlet end of the lower arc-changing device is removed, installed at the outlet end of the lower bending forming section 401, and connected to the second arc-lifting mechanism 3.

[0070] (2) When the lower arc-changing device needs to be disassembled and assembled into a lower forming candidate section 503 and a lower bending forming section 401 along the glass conveying direction, the arc-lifting unit 8 is set at the entrance end of the lower arc-changing device. After the lower arc-changing device is disassembled and assembled, the arc-lifting unit 8 at the entrance end of the lower arc-changing device is removed, installed at the entrance end of the lower bending forming section 401, and connected to the first arc-lifting mechanism 2.

[0071] (3) When the lower arc-changing device needs to be disassembled and assembled into the first lower forming candidate section 503-1, the lower bending forming section 401 and the second lower forming candidate section 503-2 along the glass conveying direction, the arc-lifting unit 8 is set at the inlet end and the outlet end of the lower arc-changing device. After the lower arc-changing device is disassembled and assembled, the arc-lifting unit 8 at the inlet end of the lower arc-changing device is removed and installed at the inlet end of the lower bending forming section 401. The arc-lifting unit 8 at the outlet end of the lower arc-changing device is removed and installed at the outlet end of the lower bending forming section 401. The two arc-lifting units 8 are respectively connected to the first arc-lifting mechanism 2 and the second arc-lifting mechanism 3.

[0072] Correspondingly, such as Figure 6 As shown, the upper arc-changing device is disassembled and assembled into a first upper forming candidate section 504-1, an upper bending forming section 402, and a second upper forming candidate section 504-2 along the glass conveying direction.

[0073] One side of the arc-lifting plate assembly 801 is a mounting plate, which connects or disconnects the arc-lifting unit 8 from the lower arc-changing device or the lower bending forming section 401. The other side of the arc-lifting plate assembly 801, away from the mounting plate, has a notch. When the arc-lifting unit 8 is connected to the lower bending forming section 401, the notch allows the lower bending forming section 401 to bend smoothly, avoiding interference with the lower forming candidate section 503. The arc-lifting unit 8 integrates the arc-lifting plate assembly 801 with the transition roller 802. Disassembly and assembly of the entire arc-lifting unit 8 can be achieved simply by disassembling and assembling the arc-lifting plate assembly 801, simplifying the disassembly and assembly process. Simultaneously, due to the integrated transition roller 802, the transition roller 802 can compensate for the horizontal distance between the lower bending forming section 401 and the lower forming candidate section 503, ensuring smooth glass transport. When disassembling and assembling using the movable first arc-lifting mechanism 2 and / or the second arc-lifting mechanism 3, it is only necessary to disconnect the connection between the arc-lifting plate assembly 801 and the lower arc-changing device, and use the first arc-lifting mechanism 2 and / or the second arc-lifting mechanism 3 to move the entire arc-lifting unit 8 to a new position and reconnect the arc-lifting plate assembly 801 with the lower bending forming section 401. There is no need to disconnect the connection between the first arc-lifting mechanism 2 and / or the second arc-lifting mechanism 3 and the arc-lifting plate assembly 801, which simplifies the disassembly and assembly operation and reduces labor intensity.

[0074] Example 6 Based on embodiments 1-4, the arc-changing system further includes a backup arc-lifting unit. The backup arc-lifting unit has a similar structure to the arc-lifting unit 8 described in embodiment 5, including two backup arc-lifting plate groups and a backup transition roller installed between the two backup arc-lifting plate groups. After the lower arc-changing device is disassembled into a lower bending forming section 401 and a lower forming candidate section 503, a backup arc-lifting unit is added to the inlet end and / or outlet end of the lower bending forming section 401. The inlet end of the lower bending forming section 401 is connected to the first arc-lifting mechanism 2 through the backup arc-lifting plate groups, and / or the outlet end of the lower bending forming section 401 is connected to the second arc-lifting mechanism 3 through the backup arc-lifting plate groups. When adding the backup arc-lifting unit, the two backup arc-lifting plate groups are detachably connected to the lower bending forming section 401 of the lower arc-changing device.

[0075] Specifically, based on the distribution of the lower bending forming section 401 and the lower forming candidate section 503 after the lower arc changing device is disassembled and assembled, the standby arc lifting unit has the following different configuration methods.

[0076] (1) When the lower arc-changing device needs to be disassembled into a lower bending forming section 401 and a lower forming candidate section 503 along the glass conveying direction, an auxiliary arc-raising unit is added to the outlet end of the lower bending forming section 401.

[0077] (2) When the lower arc-changing device needs to be disassembled into a lower forming candidate section 503 and a lower bending forming section 401 along the glass conveying direction, an auxiliary arc-raising unit is added to the inlet end of the lower bending forming section 401.

[0078] (3) The current arc-changing device is disassembled into a first lower forming candidate section 503-1, a lower bending forming section 401 and a second lower forming candidate section 503-2 along the glass conveying direction. A utility arc-lifting unit is added to the inlet and outlet ends of the lower bending forming section 401 respectively.

[0079] It should be noted that for a lower arc-changing device that does not have the aforementioned arc-raising unit 8 or a spare arc-raising unit, the connection between the chain of the corresponding arc-raising mechanism and the lower arc-changing device can be separated, and then the chain can be connected to the separated lower bending forming section 401.

[0080] Example 7 A glass bending forming device includes an upper plate, a heating furnace, a bending forming device, and an unloading device. The bending forming device includes the glass bending arc system described in any one of Examples 1-5.

[0081] In this embodiment, the example is taken where the curved glass device 1 is disassembled and assembled into a bending forming section 4 and a forming candidate section 5 along the glass conveying direction. The upper sheeting platform, heating furnace, bending forming device, and lower sheeting device can be arranged in a straight line. The glass is fed onto the upper sheeting platform, enters the heating furnace for heating and softening, first passes through the bending forming section 4 for bending, and then is conveyed through the forming candidate section 5 to the lower sheeting device for unloading. With this implementation, the glass can be directly conveyed through the forming candidate section 5 after bending, resulting in higher glass production efficiency. Alternatively, the upper sheeting platform, heating furnace, and bending forming device can be arranged in a straight line, with the lower sheeting device perpendicular to the line. The glass is fed onto the upper sheeting platform, enters the heating furnace for heating and softening, then passes through the bending forming section 4 for bending, and then is directly unloaded through the vertically arranged lower sheeting device without passing through the forming candidate section 5.

[0082] In another embodiment, the glass bending forming equipment includes a loading table, a first bending forming device, a heating furnace, a second bending forming device, and a unloading device. Both the first bending forming device and / or the second bending forming device include the glass bending arc-changing system described in any of Examples 1-5. In use, the arc-changing device 1 in the first bending forming device can be in a flattened state and used only for conveying glass. The glass is loaded onto the loading table, heated and softened in the heating furnace, then bent by the second bending forming device, and finally unloaded by the unloading device. Alternatively, the arc-changing device 1 in the second bending forming device can be in a flattened state and used only for conveying glass. The glass is loaded onto the unloading device, heated and softened in the heating furnace, then bent by the first bending forming device, and finally unloaded by the loading table.

[0083] Example 8 A glass bending forming device includes an upper plate, a heating furnace, a bending forming device, and an unloading device. The bending forming device includes the glass bending arc system described in Example 6.

[0084] In practice, the overall length of the curved glass conversion system increases due to the addition of an auxiliary arc-lifting unit. Therefore, it is necessary to adjust the relevant rollers on the side with the increased length to ensure that the conversion system can be connected to the heating furnace or the sheet-feeding device.

[0085] Specifically, when the backup arc-lifting unit is installed on the side of the lower bending forming section 401 near the heating furnace, an adjustable sheet-ejecting roller unit is provided at the outlet end of the heating furnace; when the backup arc-lifting unit is installed on the side of the lower bending forming section 401 near the sheet-feeding device, an adjustable sheet-receiving roller unit is provided at the inlet end of the sheet-feeding device; when the backup arc-lifting unit is installed at both ends of the lower bending forming section 401, adjustable sheet-ejecting roller units and sheet-receiving roller units are respectively provided at the outlet end of the heating furnace and the inlet end of the sheet-feeding device. Both the sheet-ejecting roller unit and the sheet-receiving roller unit can be telescopic rollers or flip-over rollers. Both telescopic rollers and flip-over rollers are mature designs in the field; for example, CN 207918695 U discloses a telescopic roller assembly, and CN 219340939 U discloses a swing conveying roller, i.e., a flip-over roller.

[0086] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Those skilled in the art should understand that modifications or equivalent substitutions can be made to the specific implementation of this utility model with reference to the above embodiments. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model are within the protection scope of the pending claims.
