The upper arc-changing device comprises two opposing upper arc-changing mechanisms and an upper roller conveyor connecting the two upper arc-changing mechanisms.

The upper arc-changing mechanism is composed of multiple upper arc-changing units sequentially hinged together, and the lower arc-changing mechanism is composed of multiple lower arc-changing units sequentially hinged together.

[0003] Existing large-size curved glass forming equipment cannot form small and medium-sized glass, resulting in a high rate of idleness. This causes significant waste for glass deep processing enterprises and increases their burden. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a variable arc system that can adjust the length of the variable arc device involved in glass bending and forming, while making the position of the arc lifting mechanism movable. This allows for precise adjustment of the position of the arc lifting mechanism according to the effective variable arc length of the variable arc device, thereby improving the forming accuracy of the glass and increasing the adaptability of the forming equipment, enabling a wider range of glass radii that a single machine can produce.

[0006] Its beneficial effects are as follows: the arc-changing device is disassembled into a bending forming section and a forming candidate section. The bending forming section is connected to the arc-lifting mechanism and participates in the bending forming of the glass, thereby changing the effective arc length involved in the glass bending forming within the arc-changing device. By allowing the position of the arc-lifting mechanism to be moved horizontally, the position of the arc-lifting mechanism can be precisely adjusted according to the length of the bending forming section, improving the forming accuracy of the glass. Simultaneously, it increases the adaptability of the forming equipment, allowing a wider range of glass radii that a single machine can produce. This application adapts to different bending forming section lengths by horizontally moving the position of the arc-lifting mechanism without the need to install a new arc-lifting mechanism, making operation convenient and significantly reducing the changeover time of the arc-changing system.

[0012] Its beneficial effects are: the lifting and lowering of the upper arc component drives the upper bending forming section to rise and fall, changing the distance between the upper bending forming section and the lower bending forming section, which facilitates the conveying and passing of glass.

[0013] Furthermore, the upward lifting arc assembly includes a connector and a winding connecting plate. The connector is connected to one end of the upper bending forming section, and the winding connecting plate is provided with a groove, allowing the connector to be wound around the groove of the winding connecting plate.

[0014] Its beneficial effects are: it can achieve the same lifting and lowering of the upper bending forming section, but reduces the height of the arc lifting sub-unit, thereby reducing the overall height of the arc changing system and reducing the space occupied by the forming equipment.

[0015] Furthermore, the moving component includes a moving drive and a moving connector. The moving connector is connected to the arc-lifting moving mechanism, and the moving drive is used to drive the moving connector to move along the length direction of the arc-lifting moving mechanism.

[0016] Furthermore, the arc-raising subunit also includes a locking component, which includes a locking drive and a locking connector. The locking drive is used to drive the locking connector to engage or disengage with the arc-raising moving mechanism.

[0017] Its beneficial effect is that the lifting sub-unit is locked after it is moved into place, which makes the process of lifting and bending the forming section into an arc more stable and does not affect the glass forming quality.

[0018] Furthermore, the arc-lifting subunit also includes a guide connector, which is connected to the movable guide subunit.

[0019] Its beneficial effects are: it provides guidance for the movement of the arc-lifting sub-unit, making the direction more accurate, and the arc-lifting sub-unit setting more stable.

[0020] Furthermore, the arc-lifting subunit also includes a weight-sharing mechanism, which is connected to the arc-lifting frame. The weight-sharing mechanism and the guide connector are respectively located at both ends of the arc-lifting frame.

[0021] Its beneficial effect is that the weight-sharing mechanism and the guide connector share the weight of the arc-lifting subunit at both ends of the arc-lifting frame, making the arc-lifting subunit more stable.

[0022] Furthermore, the bending forming section includes an upper bending forming section and a lower bending forming section; both the pre-arc mechanism and the post-arc lifting mechanism include two upper arc lifting sub-units and two lower arc lifting sub-units, with the two upper arc lifting sub-units respectively disposed on both sides of the glass conveying direction, and the two lower arc lifting sub-units respectively disposed on both sides of the glass conveying direction; each upper arc lifting sub-unit includes an upper arc lifting frame, an upper arc lifting assembly, and an upper moving assembly, with the upper arc lifting assembly and the upper moving assembly both disposed on the upper arc lifting frame; each lower arc lifting unit includes a lower arc lifting frame, a lower arc lifting assembly, and a lower moving assembly, with the lower arc lifting assembly and the lower moving assembly both disposed on the lower arc lifting frame; the upper moving assembly and the lower moving assembly are respectively connected to the arc lifting moving mechanism, the upper arc lifting assembly is connected to one end of the upper bending forming section, and the lower arc lifting assembly is connected to one end of the lower bending forming section.

[0024] Furthermore, it also includes an auxiliary arc-lifting mechanism, which is connected to the arc-lifting moving mechanism and is capable of horizontal movement; the auxiliary arc-lifting mechanism is connected to the middle position of the bending forming section.

[0025] Its beneficial effects are: it assists in lifting and bending the forming section, improving the arc shape of the forming section, thereby improving the accuracy of glass arc forming.

[0026] The beneficial effects of this utility model are: 1. This application disassembles the arc-changing device into a bending forming section and a forming candidate section. The bending forming section is connected to the arc-lifting mechanism to participate in the bending forming of the glass, thereby changing the effective arc length participating in the bending forming of the glass in the arc-changing device, improving the utilization rate of the forming equipment, and making the glass radius range that one machine can produce wider.

[0027] 2. By setting up a horizontally movable arc-lifting mechanism, the position of the arc-lifting mechanism can be flexibly adjusted. Regardless of where the arc-changing device is disassembled and assembled into the bending forming section and the forming candidate section, and regardless of how the length of the bending forming section changes, its horizontal position can be precisely adjusted by moving the front arc-lifting mechanism and / or the rear arc-lifting mechanism. This improves the glass forming accuracy, ensures reliable connection and power transmission, and fundamentally guarantees the normal operation of the bending forming section and the reliability of arc formation. This application can adapt to different bending forming section lengths simply by moving the position of the arc-lifting mechanism, without the need to install a new arc-lifting mechanism, making operation convenient and greatly reducing the changeover time of the arc-changing system.

[0028] 3. This application enables the independent lifting of the four lifting points of the bending forming section into an arc, thereby producing unequal arc glass and irregularly shaped glass. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] Please see Figure 1-3 and Figure 7As shown, Embodiment 1 of this utility model provides an arc-changing system, including a frame, an arc-changing device 9, a front arc-raising mechanism 10, and a rear arc-raising mechanism 11. The arc-changing device 9 includes an upper arc-changing device and a lower arc-changing device. The arc-changing device 9 can be detachably assembled into a bending forming section 91 and a forming candidate section 92. There is one bending forming section 91 and one or two forming candidate sections 92. The number of forming candidate sections 92 depends on whether they are located on one or both sides of the bending forming section 91. When the forming candidate section 92 is located on one side of the bending forming section 91, there is one of it; when the forming candidate section 92 is located on both sides of the bending forming section 91, there are two of it. The bending forming section 91 is used for bending and forming glass, and the forming candidate section 92 is used for conveying glass or for changing the length of the bending forming section 91. For example, the forming candidate section 92 can be partially or completely incorporated into the bending forming section 91, or the bending forming section 91 can be partially incorporated into the forming candidate section 92 to adjust the length of the bending forming section 91. The front arc mechanism 10 is connected to the front end of the bending forming section 91 in the glass conveying direction, and the rear arc lifting mechanism 11 is connected to the rear end of the bending forming section 91 in the glass conveying direction; an arc lifting moving mechanism is provided on the frame, and the front arc mechanism 10 and / or the rear arc lifting mechanism 11 are connected to the arc lifting moving mechanism and can move horizontally.

[0033] By disassembling the arc-changing device into a bending forming section 91 and a forming candidate section 92, the two ends of the bending forming section 91 are connected to the front arc mechanism 10 and the rear arc-lifting mechanism 11 respectively in the length direction to participate in the bending forming of the glass. This changes the effective arc length of the arc-changing device 9 in the glass bending forming, improves the utilization rate of the forming equipment, and makes the glass radius range that one machine can produce wider. Due to the change in the length of the bending forming section 91, the positions of the front arc mechanism 10 and the rear arc-lifting mechanism 11 also need to be changed accordingly. Therefore, the front arc mechanism 10 and / or the rear arc-lifting mechanism 11 are connected to the arc-lifting moving mechanism, so that the front arc mechanism 10 and the rear arc-lifting mechanism 11 can move horizontally in the glass conveying direction. This facilitates the adjustment of the position of the front arc mechanism 10 and / or the rear arc-lifting mechanism 11 in the glass conveying direction, and realizes the flexible adjustment of the position of the arc-lifting mechanism. Regardless of where the arc-changing device is disassembled and assembled into the bending forming section 91 and the forming candidate section 92, and regardless of how the length of the bending forming section 91 changes, its horizontal position can be precisely adjusted by moving the front arc-raising mechanism 10 and / or the rear arc-raising mechanism 11. This improves the glass forming accuracy, ensures reliable connection and power transmission, and fundamentally guarantees the normal operation and arc-forming reliability of the bending forming section 91. This application can adapt to different bending forming section 91 lengths simply by moving the position of the arc-raising mechanism, without the need to install a new arc-raising mechanism. This convenient operation greatly reduces the changeover time of the arc-changing system.

[0034] The bending forming section 91 includes an upper bending forming section and a lower bending forming section; the front arc lifting mechanism 10 includes two arc lifting sub-units, which are respectively located on both sides of the glass conveying direction; the rear arc lifting mechanism 11 also includes two arc lifting sub-units, which are respectively located on both sides of the glass conveying direction. Each arc lifting sub-unit includes an arc lifting frame 1, an upper arc lifting component 3, a lower arc lifting component 2, and a moving component 6. The upper arc lifting component 3, the lower arc lifting component 2, and the moving component 6 are all mounted on the arc lifting frame 1. The upper arc lifting component 3 is connected to one end of the upper bending forming section, the lower arc lifting component 2 is connected to one end of the lower bending forming section, and the moving component 6 is connected to the arc lifting moving mechanism. The four arc lifting sub-units are respectively connected to the two ends of the upper bending forming section in the length direction and the two ends of the lower bending forming section in the width direction, for a total of eight lifting points, realizing independent driving of the four lifting points of each of the upper and lower bending forming sections, which can produce unequal arc glass and irregularly shaped glass. The upper arc-lifting component 3, the lower arc-lifting component 2, and the moving component 6 are all mounted on the arc-lifting frame 1, achieving an integrated modular design for the arc-lifting subunits. This improves the integration level of the arc-lifting subunits, reduces their size, and facilitates maintenance and replacement. The two arc-lifting subunits of the front arc-lifting mechanism 10 and the two arc-lifting subunits of the rear arc-lifting mechanism 11 are located on opposite sides of the glass conveying direction, thus avoiding the air boxes and ducts in the forming equipment and not interfering with the movement of the front arc-lifting mechanism 10 and / or the rear arc-lifting mechanism 11 along the glass conveying direction.

[0035] Specifically, the arc-lifting moving mechanism includes two moving guide sub-units 5, which are respectively located on both sides of the glass conveying direction. The lower end of the arc-lifting frame 1 has a base plate 101. The moving guide sub-units 5 are located below the base plate 101 and at one end of the width direction of the base plate 101. The moving guide sub-units 5 include a support plate 51 and a slide rail 52 set on the support plate 51. The arc-lifting sub-unit also includes a guide connector 53, which is connected to the moving guide sub-units 5. The guide connector 53 is a slider set on the slide rail 52. A moving rack 54 is provided on one side of the support plate 51. The moving guide sub-units 5 provide guidance for the horizontal movement of the arc-lifting sub-units, ensuring the accuracy of the movement direction. The moving guide sub-units 5 are respectively located on both sides of the glass conveying direction, thereby avoiding the bellows and air ducts in the forming equipment and not interfering with the movement of the front arc-lifting mechanism 10 and / or the rear arc-lifting mechanism 11 along the glass conveying direction.

[0036] The arc-lifting subunit also includes a weight-sharing mechanism 4, which is connected to the arc-lifting frame 1. The weight-sharing mechanism 4 and the guide connector 53 are respectively located at both ends of the arc-lifting frame 1. Specifically, in this embodiment, the weight-sharing mechanism 4 is also located below the base plate 101 and at the other end of the width direction of the base plate 101. The weight of the arc-lifting subunit is shared by the moving guide subunits 5 at both ends of the width direction below the base plate 101 and the weight-sharing mechanism 4, making the arc-lifting subunit more stable. In this embodiment, the weight-sharing mechanism 4 is configured as a row of pulleys arranged along the glass conveying direction. The lower end of the pulleys is rolledly connected to the frame, and the pulleys can reduce the friction force when the arc-lifting subunit moves horizontally.

[0037] The upper arc lifting assembly 3 includes a connector and a winding connecting plate 31. The connector is connected to one end of the upper bending forming section. The winding connecting plate 31 has a groove, allowing the connector to be wound within the groove. The connector can be a flexible strip such as a plate chain, roller chain, wire rope, steel cable, or steel strip. The upper arc lifting assembly 3 also includes an upper arc lifting drive motor, the output shaft of which is connected to the winding connecting plate 31. The groove is an annular groove used to accommodate the connector. The lower arc lifting assembly 2 includes a lower arc lifting drive motor and a sprocket mounted on the output shaft of the lower arc lifting drive motor. The sprocket is connected to one end of the lower bending forming section via a chain. The upper arc lifting assembly 3 uses a winding connecting plate 31 with a groove, allowing the connector to be accommodated within the groove. This enables the upper bending forming section to be raised and lowered, changing the distance between the upper and lower bending forming sections for easier glass transport. Simultaneously, it reduces the height of the arc lifting subunit, thus reducing the overall height of the arc-changing system and minimizing the space occupied by the forming equipment.

[0038] The moving component 6 includes a moving drive component 61 and a moving connector 62. The moving connector 62 is connected to the arc-lifting moving mechanism. The moving drive component 61 drives the moving connector 62 to move along the length direction of the arc-lifting moving mechanism. The moving drive component 61 includes a moving motor, and the moving connector 62 is a drive gear located at the end of the output shaft of the moving motor. The drive gear is located below the base plate 101 and meshes with the moving rack 54. This embodiment uses a gear and rack linear module for illustration. In other embodiments, linear motion modules such as synchronous belt modules, lead screw modules, linear motor modules, pneumatic linear modules, and electric cylinder modules can be used. When a lead screw module is used, the moving connector 62 is a threaded sleeve. The arc-lifting moving mechanism includes a lead screw, which is located on one side of the support plate 51. The moving connector 62 is sleeved on the lead screw of the arc-lifting moving mechanism. The moving drive component 61 is connected to the lead screw and drives the lead screw to rotate, thereby moving the moving connector 62 and the entire arc-lifting subunit along the length direction of the lead screw.

[0039] The arc-raising subunit also includes a locking assembly 7, which includes a locking drive 71 and a locking connector 72. The locking drive 71 drives the locking connector 72 to engage or disengage with the arc-raising moving mechanism. The locking drive 71 is a drive cylinder, a drive hydraulic cylinder, or a drive electric push rod. The locking connector 72 is a locking rack located at the end of the locking drive 71, which can engage with the moving rack 54. When the arc-raising subunit moves to the target position, the locking drive 71 actuates, pushing the locking rack to engage tightly with the moving rack 54, achieving mechanical locking and preventing displacement. In other embodiments, the locking connector 72 can be a pin. When the arc-raising subunit moves to the target position, the locking drive 71 actuates, pushing the pin into the corresponding insertion hole of the support plate 51, achieving mechanical locking and preventing displacement. The locking component 7 can lock the arc-lifting subunit after it has been moved into place, making the arc-forming process of the lifting and bending forming section 91 more stable and not affecting the glass forming quality.

[0040] First, disconnect the connector from the arc-changing device 9. Disassemble the arc-changing device 9 into a bending forming section 91 and a forming candidate section 92. Then, move the arc-raising sub-units of the front arc mechanism 10 and the rear arc-raising mechanism 11 along the glass conveying direction to a suitable position, so that the upper arc-raising assembly 3 and the lower arc-raising assembly 2 are accurately aligned and connected with the ends of the bending forming section 91. Finally, lock the locking assembly 7 to start working. This application allows both the front arc mechanism 10 and the rear arc-raising mechanism 11 to move; it also allows the front arc mechanism 10 to move alone; in addition, combined with Figure 7 The rear lifting mechanism 11 can be moved independently in this application.

[0041] The front arc mechanism 10 and / or the rear arc lifting mechanism 11 are connected to the arc lifting moving mechanism and can move horizontally under the guidance of the arc lifting moving mechanism. By moving the front arc mechanism 10 and the rear arc lifting mechanism 11 horizontally, the horizontal distance between them can be adjusted to accommodate bending forming segments 91 of different lengths.

[0042] Of course, this utility model is not limited to the embodiments described above. Several other embodiments based on the design concept of this utility model are also provided below.

[0043] For example, in Embodiment 2, unlike the implementation described above, a combination of Figure 4-6As shown, the arc-lifting subunit also includes a lifting assembly 8, which is connected to the upper arc-lifting assembly 3 and is used to control the up-and-down movement of the upper arc-lifting assembly 3. The lifting assembly 8 includes a lifting screw 81 and a lifting motor 82 located at the lower end of the base plate 101. The arc-lifting frame 1 has multiple guide rods that pass through the upper arc-lifting assembly 3 and slide in cooperation with it. The lifting screw 81 is rotatably mounted on the arc-lifting frame 1. The output shaft of the lifting motor 82 is connected to the lifting screw 81 via a coupling. The lifting screw 81 has a threaded nut seat that connects to the upper arc-lifting assembly 3. In this embodiment, the upper arc-lifting assembly 3 is connected to one end of the upper bending forming section via a chain.

[0044] In addition, in this embodiment, an intermediate gear 63 is provided between the movable connector 62 and the movable rack 54. The intermediate gear 63 is rotatably connected to the base plate 101 through a rotating shaft, and the gear 63 meshes with the drive gear and the movable rack 54 respectively.

[0045] For example, in Embodiment 3, unlike the embodiments described above, the pre-arc mechanism 10 includes two upward-lifting arc sub-units and two downward-lifting arc sub-units. The two upward-lifting arc sub-units are respectively located on both sides of the glass conveying direction, and the two downward-lifting arc sub-units are also respectively located on both sides of the glass conveying direction. The rear-lifting arc mechanism 11 includes two upward-lifting arc sub-units and two downward-lifting arc sub-units. The two upward-lifting arc sub-units are respectively located on both sides of the glass conveying direction, and the two downward-lifting arc sub-units are also respectively located on both sides of the glass conveying direction. Each upward-lifting arc sub-unit includes an upward-lifting arc frame, an upward-lifting arc assembly 3, and an upward-moving assembly. The upward-lifting arc assembly 3 and the upward-moving assembly are both mounted on the upward-lifting arc frame. Each downward-lifting arc sub-unit includes a downward-lifting arc frame, a downward-lifting arc assembly 2, and a downward-moving assembly. The downward-lifting arc assembly 2 and the downward-moving assembly are both mounted on the downward-lifting arc frame. The upward-lifting arc assembly 3 is connected to one end of the upper bending forming section, the upward-moving assembly is connected to the arc-lifting moving mechanism, the downward-lifting arc assembly 2 is connected to one end of the lower bending forming section, and the downward-moving assembly is connected to the arc-lifting moving mechanism. The upward and downward arc sub-units have the same structure and size as the upward arc sub-unit.

[0046] For example, in Embodiment 4, unlike the embodiments described above, the lifting assemblies at both ends of the glass conveying direction share a single lifting motor. Specifically, the lower lifting assembly 2 of the front lifting mechanism 10 and the lower lifting assembly 2 of the rear lifting mechanism 11 on the same side are connected by a transmission assembly. The transmission assembly includes a first transmission shaft and a second transmission shaft. The second transmission shaft is connected to a sprocket of the lower lifting assembly 2. The first transmission shaft is equipped with a first bevel gear, and the second transmission shaft is equipped with a second bevel gear that meshes with the first bevel gear. The lifting motor is connected to a dual-output reducer, and the two output ends of the dual-output reducer are respectively connected to a third transmission shaft. The third transmission shaft and the first transmission shaft are connected by a gear reversing device. The transmission method of the upper lifting assembly 3 is the same as that of the lower lifting assembly 2.

[0047] In Example 5, as Figure 8 As shown, the arc-changing system also includes an auxiliary arc-lifting mechanism 12, which is connected to the arc-lifting moving mechanism and can move horizontally. The auxiliary arc-lifting mechanism 12 is connected to the middle position of the bending forming section 91. This middle position refers to the location in the glass conveying direction, inside the connection point between the front arc-lifting mechanism 10 and the rear arc-lifting mechanism 11 and the bending forming section 91, and located on both sides of the arc-changing reference. In the prior art, the arc-changing reference is the arc-changing center of the arc-changing device. The arc-changing references of the upper and lower arc-changing devices correspond vertically. The lower arc-changing device is fixed at the arc-changing reference, and its two ends are lifted upwards by the arc-lifting mechanism to form an arc. The upper arc-changing device can only slide up and down at the arc-changing reference and cannot move left or right. Similarly, the arc-changing reference of the bending forming section 91 is clearly deducible by those skilled in the art based on this invention.

[0048] Specifically, the auxiliary arc-lifting mechanism 12 includes four auxiliary arc-lifting sub-units, which are respectively arranged on both sides of the glass conveying direction, with the two auxiliary arc-lifting sub-units on the same side located inside the two arc-lifting sub-units in the glass conveying direction. In one embodiment, the auxiliary arc-lifting sub-unit has the same structure as the arc-lifting sub-unit, and is connected to the middle position of the bending forming section 91 to assist in lifting the middle position of the bending forming section 91, thereby improving the arc-forming accuracy of the bending forming section 91. In another embodiment, the auxiliary arc-lifting sub-unit does not include the upper arc-lifting component 3, and the remaining structure is the same as the arc-lifting sub-unit. The auxiliary arc-lifting sub-unit is connected to the middle position of the lower bending forming section to assist in lifting the middle position of the lower bending forming section, thereby improving the arc-forming accuracy of the bending forming section 91.

[0049] It should be noted that the above embodiments are only used to illustrate the present utility model, but the present utility model is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
