For example, the curved tempered glass forming device disclosed in Patent No. CN201910742701.5 is equipped with multiple lower arc plates and corresponding flexible shaft rollers. The accuracy of the arc grooves on each lower arc plate must be ensured during production. During installation, the height of each lower arc plate and the height of each flexible shaft roller must be adjusted to ensure that the glass remains within a forming conveying surface during the forming process to ensure the forming accuracy of the curved glass. This results in a complex structure, difficult installation, high requirements for arc plate production accuracy, and high costs. Summary of the Invention

[0006] Its beneficial effect is that two curved plates, multiple lower connecting plates, and a central support beam are used to form a space for the flexible shaft roller to be installed, thereby forming a space for the shaping and conveying of curved glass. Compared with the CN201910742701.5 patent, the intermediate curved plate is eliminated and replaced by an intermediate support beam, which has a simpler structure, easier installation, and lower cost. In addition, the machining accuracy of the intermediate support beam and the lower connecting plate is easy to ensure, so there is no need to adjust the height of the flexible shaft support seat in the middle part of the glass conveying direction, and the accuracy of the glass forming conveying surface in the conveying direction can be guaranteed, making glass forming more precise.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention in any way.

[0026] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. Example 1

[0027] As attached Figure 1 As shown, a curved glass forming device includes two lower arc plates 1, multiple lower connecting plates 2, a middle support beam 3, and multiple flexible shaft rollers 4. The two lower arc plates 1 are respectively arranged at the front and rear ends of the glass conveying direction. Both lower arc plates 1 are provided with an arc groove for the curved glass to pass through. The arc shape of the arc groove is adapted to the target arc shape of the curved glass. For example, if the curved glass is semicircular, the arc groove is also semicircular, but the radius of the semicircle of the arc groove is larger than the semicircle of the curved glass to reserve space for the installation of the flexible shaft rollers 4.

[0028] One end of the central support beam 3 is connected to the middle of the arc-shaped groove of the lower arc plate 1 at the front end of the glass conveying direction, and the other end of the central support beam 3 is connected to the middle of the arc-shaped groove of the lower arc plate 1 at the rear end of the glass conveying direction. One end of multiple lower connecting plates 2 is connected to the lower arc plate 1 at the front end of the glass conveying direction, and the other ends of multiple lower connecting plates 2 are connected to the lower arc plate 1 at the rear end of the glass conveying direction. Multiple lower connecting plates 2 are arranged at intervals along the arc surface of the arc-shaped groove of the lower arc plate 1. Multiple flexible shaft bases are arranged at intervals on the top of the lower connecting plate 2 along the glass conveying direction. The flexible shaft roller 4 includes a flexible shaft and multiple rollers. The flexible shaft is inserted into the flexible shaft base, and multiple rollers are fixedly mounted on the flexible shaft. Multiple flexible shaft rollers are arranged at intervals along the glass conveying direction, and together form a forming conveying surface for curved glass to pass through.

[0029] Two arc plates, multiple lower connecting plates, and a middle support beam are used to form a space for the flexible shaft roller to pass through, thereby forming a forming and conveying space for the curved glass. Compared with the CN201910742701.5 patent, the middle arc plate is eliminated, the structure is simpler, the installation is simpler, and the cost is low. In addition, the processing accuracy of the middle support beam and the lower connecting plate is easy to ensure. It is only necessary to adjust the installation position of the middle support beam and the ends of the lower connecting plate on the lower arc plate to make the flexible shaft roller present the desired target arc shape, thereby ensuring the accuracy of the glass forming conveying surface in the conveying direction and making the glass forming more precise. However, the solution of the CN201910742701.5 patent requires multiple middle arc plates to provide transmission support in the middle of the flexible shaft roller. Therefore, it requires the coordination of factors such as the installation position of the middle arc plate, the processing accuracy of the middle arc plate, and the installation position of the lower connecting plate on multiple arc plates. It is often difficult to ensure the accuracy of the glass forming conveying surface in the conveying direction.

[0030] As attached Figure 2 As shown, a plurality of flexible shaft support seats 31 are arranged at intervals along the glass conveying direction on the middle support beam 3. The flexible shaft support seats 31 are in a "U" shape, that is, the middle part of the flexible shaft support seat 31 is lower and the two sides are higher. Holes are provided on both sides of the flexible shaft support seat 31, and the flexible shaft of the flexible shaft roller 4 is passed through the holes of the flexible shaft support seat 31. A flexible shaft sprocket 32 is fixedly provided in the middle part of the flexible shaft, that is, at a position corresponding to the middle part of the flexible shaft support seat 31, and there is a space for the chain to pass through between the flexible shaft sprocket 32 and the flexible shaft support seat 31. A motor and a tensioning sprocket are provided below the middle support beam 3. The chain passes through the above-mentioned space. The motor drives the chain to rotate, and drives the flexible shaft sprocket to rotate, thereby rotating the flexible shaft roller 4.

[0031] In other embodiments, multiple groups of flexible shaft support seats 31 are arranged at intervals along the glass conveying direction on the middle support beam 3. Each group of flexible shaft support seats 31 has two flexible shaft support seats 31. The two flexible shaft support seats 31 are respectively arranged on both sides of the middle support beam 3 perpendicular to the glass conveying direction. The flexible shaft support seats 31 are provided with holes, and the flexible shaft of the flexible shaft roller 4 is inserted into the holes of the flexible shaft support seats 31. A flexible shaft sprocket 32 is fixedly provided in the middle of the flexible shaft, that is, at a position corresponding to the position between the two flexible shaft support seats 31 of each group. There is a space between the two flexible shaft support seats 31 for the flexible shaft sprocket 32 to be installed, and there is a space between the bottom of the flexible shaft sprocket 32 and the top surface of the middle support beam 3 for the chain to pass through.

[0032] A redirecting sprocket 33 is provided at both the front and rear ends of the central support beam 3. The top of the redirecting sprocket 33 is higher than the bottom of the flexible shaft sprocket 32. The chain passes from the bottom of the flexible shaft sprocket 32 and winds around to the top of the redirecting sprocket 33. The redirecting sprocket 33 changes the chain's length direction from horizontal to vertical, allowing for the placement of the motor, tensioning sprocket, and other chain drive mechanisms within the larger space below the central support beam 3, facilitating the layout of the transmission mechanism. The higher top of the redirecting sprocket 33 acts as a tensioner on the chain, ensuring that the chain adheres to the flexible shaft sprocket 32, thereby ensuring more stable transmission.

[0033] In this embodiment, the curved grooves of the two lower curved plates 1 have the same size and curvature. After the curved glass is initially formed, it is precisely stabilized in this device, achieving the target curvature of the curved glass. In other embodiments, the curved groove of the lower curved plate 1 at the rear end of the glass conveying direction has a greater curvature than the curved groove of the lower curved plate 1 at the front end of the glass conveying direction. The curvature of the curved glass gradually increases in the forming device, and the target curved surface is formed after passing through the lower curved plate 1 at the rear end of the glass conveying direction. Example 2

[0034] As attached Figure 3As shown, based on Example 1, the curved glass forming device also includes two upper arc plates 5 and multiple upper connecting plates 6. The two upper arc plates 5 are respectively arranged at the front end and the rear end of the glass conveying direction. The lower part of the upper arc plate 5 has an arc surface. The arc shape of the arc surface is adapted to the target arc shape of the curved glass, and the arc surface of the upper arc plate 5 is adapted to the arc groove of the lower arc plate 1. One end of the multiple upper connecting plates 6 is arranged on the upper arc plate 5 at the front end of the glass conveying direction, and the other end of the multiple upper connecting plates 6 is arranged on the upper arc plate 5 at the rear end of the glass conveying direction. The multiple upper connecting plates 6 are arranged at intervals along the arc surface of the upper arc plate 5 perpendicular to the glass conveying direction. A plurality of pressure wheels are arranged at intervals on the upper connecting plate 6 along the glass conveying direction, and a space for the curved glass to pass through and be formed is formed between the pressure wheels and the soft shaft roller.

[0035] The curved glass forming device also includes a plurality of positioning wheels 7, which are arranged on the upper connecting plate 6 at the upper end and are located on both sides of the glass conveying direction. The positioning wheels 7 limit the top of the curved glass to ensure stability during the glass forming and conveying process.

[0036] The forming device is also provided with a lifting mechanism, which can drive the upper arc plate 5 to rise and fall, thereby adjusting the distance between the upper arc plate 5 and the lower arc plate 1 to adapt to the forming of glass of different thicknesses. The lifting mechanism can be a common lifting method such as chain lifting, slide rail lifting, and screw lifting. Example 3

[0037] As attached Figure 4 As shown, a curved glass production line includes a loading platform 101, a heating furnace 102, a first forming device 103, a second forming device 104, a tempering device 105, and a lowering platform 106, arranged in sequence along the glass conveying direction. The first forming device 103 is a flexible shaft gradual forming device or a flexible shaft bending forming device. A flexible shaft gradual forming device is a forming device that gradually transforms the glass from a flat surface into a curved surface during conveyance. A flexible shaft bending forming device is a forming device that bends the flat glass into a curved surface after conveying it into the forming device. Both flexible shaft gradual forming devices and flexible shaft bending forming devices are common forming devices in the art, and their specific structures are not described in detail here. The second forming device 104 uses the forming device described in Example 1 or Example 2.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Those skilled in the art should understand that the specific implementation methods of the present invention can be modified or replaced with equivalents with reference to the above embodiments. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of protection of the pending claims.
