[0029] All terms used in this application have the same meanings as understood by those of ordinary skill in the art to which this application belongs, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, such as, should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such here.

[0030] Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods and devices should be regarded as part of the specification.

[0031] As Figures 1 to 3 shown, the air-floating conveying device disclosed in Embodiment 1 of this application includes: a frame assembly 10, a conveying assembly 20 and an air-floating assembly 30. The conveying assembly 20 includes a plurality of rubber conveying rollers 21. The plurality of rubber conveying rollers 21 are rotatably connected to the frame assembly 10. The plurality of rubber conveying rollers 21 are arranged at intervals. The air-floating assembly 30 includes a plurality of air outlet structures 31. The plurality of air outlet structures 31 are respectively located between adjacent rubber conveying rollers 21. The air outlet structure 31 includes a plurality of air outlets 311. The plurality of air outlets 311 are arranged in sequence along a direction parallel to the axis of the rubber conveying roller 21.

[0032] Applying the technical solution of Embodiment 1, the glass at a relatively high temperature moves to the conveying component. The surface rubber of the rubber conveying roller 21 wears severely in the high-temperature environment. Multiple air outlets 311 discharge air simultaneously, applying an upward force to the glass, reducing the contact force between the glass and the rubber conveying roller 21, and avoiding the influence of the worn rubber conveying roller 21 on the glass surface, which may cause poor surface quality of the glass. The technical solution of Embodiment 1 effectively solves the problem in the prior art that during the glass production process, the worn rubber conveying roller causes scratches on the glass surface, affecting the surface quality of the glass.

[0033] As Figure 1 shown, in the technical solution of Embodiment 1, the air outlets 311 of adjacent air outlet structures 31 are arranged staggeredly. The airflow formed by multiple staggeredly arranged air outlets 311 applies a more uniform external force to the glass, ensuring the stability of the glass movement.

[0034] As Figure 1 shown, in the technical solution of Embodiment 1, the air floating component 30 further includes an air inlet pipeline 32. The first end of the air inlet pipeline 32 is connected to an air pump, and the second end of the air inlet pipeline 32 has a first branch 321 and a second branch 322. The first ends of multiple air outlet structures 31 are connected to the first branch 321, and the second ends of multiple air outlet structures 31 are connected to the second branch 322. The air pump supplies air to the air inlet pipeline 32. The airflow flows into the first branch 321 and the second branch 322 respectively, and then flows into the air outlet structures 31 from both ends of the air outlet structures 31, and then sprays out from the air outlets 311. Since gas is introduced into both ends of the air outlet structure 31, it avoids the problem that the distance between the air outlets 311 on the air outlet structure 31 from the air inlet position is too far, resulting in too large differences in the gas flow rate and velocity of each air outlet 311, causing uneven force on the glass.

[0035] As Figure 2 and Figure 3As shown, in the technical solution of the first embodiment, the first branch 321 includes a plurality of first pipe segments 3211. The plurality of first pipe segments 3211 are U-shaped. An air outlet structure 31 is provided between two adjacent first pipe segments 3211. The air outlet structure 31 is communicated with the first pipe segments 3211 on both sides thereof. The second branch 322 includes a plurality of second pipe segments. The plurality of second pipe segments are U-shaped. An air outlet structure 31 is provided between two adjacent second pipe segments. The air outlet structure 31 is communicated with the second pipe segments on both sides thereof. Setting the first pipe segments 3211 and the second pipe segments to be U-shaped avoids interference between the first branch 321 and the second branch 322 and the rubber conveying roller 21, and at the same time ensures that the distance between the air outlet structure 31 and the upper edge of the rubber conveying roller 21 is relatively close, so that the glass receives a sufficiently large upward external force, avoiding the situation that due to the relatively large distance between the air outlet structure 31 and the glass, the airflow is dispersed, resulting in a relatively small force on the glass from the airflow, and a relatively large contact force between the glass and the rubber conveying roller 21, which may cause soft abrasion between the glass and the worn rubber conveying roller.

[0036] As Figure 2 and Figure 3 shown, in the technical solution of the first embodiment, the air floating assembly 30 further includes a vertical driving structure 33. The vertical driving structure 33 is connected to the air inlet pipeline 32. The vertical driving structure 33 includes a lifting cylinder and a partition plate. The lifting cylinder is connected to the partition plate. The lifting cylinder is connected to the partition plate to drive the partition plate to move up and down. The air floating assembly 30 is driven to move in the vertical direction to change the distance between the air floating assembly 30 and the glass. Under the same gas flow rate and gas pressure, the smaller the distance between the air floating assembly 30 and the glass, the greater the external force on the glass from the airflow. Therefore, the distance between the air floating assembly 30 and the glass can be changed according to glass of different unit masses, so that the glass receives an appropriate external force from the airflow. It should be noted that the air floating assembly can also be an electric push rod, an air floating lifter or other structures that can achieve vertical driving.

[0037] As Figures 1 to 3 shown, in the technical solution of the first embodiment, the rubber conveying roller 21 includes a rotating shaft 211 and a rubber supporting portion 212. The rotating shaft 211 is rotatably connected to the frame assembly 10. The rubber supporting portion 212 is connected to the rotating shaft 211. The rotating shaft 211 drives the rubber supporting portion 212 to rotate, and the glass moves translationally under the friction force from the rubber supporting portion 212 to realize glass conveying. A plurality of rubber supporting portions 212 are provided on each rotating shaft 211. The plurality of rubber supporting portions 212 are arranged at intervals, reducing the contact area between the rubber supporting portion 212 and the glass, and thus reducing abrasion.

[0038] As Figures 1 to 3As shown in the figure, in the technical solution of Embodiment 1, the rubber support parts 212 of adjacent rubber conveying rollers 21 are arranged staggeredly. The staggeredly arranged rubber support parts 212 provide more uniform supporting force for the glass, and the position of the glass is not likely to shift during movement.

[0039] The difference between the technical solution of Embodiment 2 and that of Embodiment 1 is that along the conveying direction of the conveying assembly 20, the sizes of the air outlet openings 311 of multiple air outlet structures 31 gradually increase. Since the temperature of the glass is relatively high near the conveying direction of the conveying assembly 20, and the temperature of the glass gradually decreases as the glass is conveyed, the rubber conveying rollers 21 at the rear section of the conveying assembly 20 are less worn and are not likely to cause scratches to the glass. The glass can receive a relatively large contact force from the rubber conveying rollers 21. The air outlet openings 311 are relatively large, and the pressure of the ejected air flow is relatively small. The relatively large contact force between the glass and the rubber conveying rollers 21 can also meet the requirement that no scratches are generated on the lower surface of the glass.

[0040] The difference between the technical solution of Embodiment 3 and that of Embodiment 1 is that the air floating assembly 30 further includes multiple air supply structures, and the multiple air supply structures are arranged in one-to-one correspondence with the air outlet structures 31. The multiple air supply structures supply air to different air outlet structures 31 respectively. On the premise of meeting the requirement that no scratches are generated on the glass, the air supply volume of the air supply structures at the rear section of the conveying assembly 20 is minimized as much as possible to save energy.

[0041] According to another aspect of the present application, a glass production line is further provided. The glass production line adopts the above-mentioned air floating conveying equipment. The glass production line includes an annealing furnace and a cutting device. The feeding end of the conveying assembly 20 is correspondingly arranged with the outlet of the annealing furnace, and the discharging end of the conveying assembly 20 is correspondingly arranged with the cutting device. The temperature of the glass after annealing in the annealing furnace is relatively high, which causes the rubber conveying rollers 21 to be worn in a high-temperature environment. The worn rubber conveying rollers 21 provide frictional force for the lower surface of the glass, resulting in scratches on the lower surface of the glass. As the glass moves, the temperature of the glass gradually decreases. Therefore, the degree of wear of the rubber conveying rollers 21 far from the annealing furnace is small, and the surface of the glass is not easily scratched. The setting of the air floating conveying device avoids the problem that the contact force between the glass and the rubber conveying rollers 21 is relatively large, so the frictional force is also relatively large, resulting in scratches on the lower surface of the glass.

[0042] As described above, as shown in the above figures, the present application includes a first component (air pump), a second component (air pump), a third component (pressure gauge), a fourth component (air outlet structure 31), a fifth component (partition), and a sixth component (air floating lifter). Embodiment: When the first or second component is turned on, gas is discharged from the upper surface air outlet (air outlet 311) of the air floating strip (air outlet structure 31) along the direction marked by the arrow in the pipeline in the above figure; for the glass plate running normally above the cold end roller path, an air film is formed between the glass plate and the partition, and the air film makes the glass plate float, so that the lower surface of the glass is separated from or not in contact with the rubber ring (rubber support part 212) of the cold end roller path; the pressure of the glass plate contacting the roller path rubber ring is adjusted through the wind pressure detector in cooperation with the air floating lifting device, thereby reducing or eliminating the soft scratch on the lower surface of the glass caused by the aging of the cold end roller path rubber ring. An air floating device (air floating assembly 30) is installed in the cold end emergency falling plate roller path area to fully reduce the contact force between the rubber roller and the lower surface of the glass, thereby reducing soft scratches and improving the quality of the lower surface of the glass.
