[0022] The present invention will now be further described with reference to the accompanying drawings.

[0023] like Figures 1 to 8As shown, an air-float steering device includes a steering housing 1 and nozzles 2. The steering housing 1 has a static pressure chamber 12 inside. An air inlet 18 is provided on one side of the steering housing 1, communicating with the static pressure chamber 12. A steering arc surface 11 is provided on the top of the steering housing 1, with several mounting holes 13 arranged radially on the arc surface 11. The nozzles 2 are fixed to the mounting holes 13. Multiple nozzles 2 are also arranged along the steering arc surface 11. An air outlet is provided on the top of each nozzle 2, communicating with the static pressure chamber 12. A substrate 8 is steered through the steering arc surface 11, and the air outlet is used to form an air cushion layer between the substrate 8 and the steering arc surface 11. The air outlet includes an air outlet slit 25 and / or an air outlet hole 24. Specifically, the air outlet can adopt a slit structure, with the air outlet slit 25 radially arranged along the turning arc surface 11. There is at least one air outlet slit 25, which is located at the center of the top of the nozzle 2 when there is only one air outlet slit 25; when two air outlet slits 25 are used, they can be symmetrically arranged on both sides of the top of the nozzle 2. The width of the air outlet slit 25 is 1~8mm, selected according to actual needs. The air outlet can also adopt an air outlet hole 24, arranged in an array. The diameter of the air outlet hole 24 is 1~20mm, selected according to actual needs. The air outlet hole 24 can also be a waist-shaped hole or other shaped hole. When only the air outlet hole 24 is used, a perforated plate is formed on the top of the nozzle 2. The air outlet can also be a combination structure of air outlet slit 25 and air outlet hole 24, with the air outlet slit 25 arranged on both sides of the air outlet hole 24, and the air outlet hole 24 arranged in an array. Air enters the static pressure chamber 12 through the air inlet 18, and then blows onto the surface of the substrate 8 through the air outlet, forming an air cushion layer between the substrate 8 and the nozzle 2 deflector. The air cushion layer provides support and lifts the substrate 8, preventing the substrate 8 from directly contacting the deflector.

[0024] There is at least one mounting hole 13, and each mounting hole 13 corresponds to a nozzle 2. Multiple mounting holes 13 are arranged in an array along the arc surface. When only one mounting hole 13 is used, it is located at the center of the turning arc surface 11.

[0025] Because an air cushion layer is formed between the substrate 8 and the turning arc surface 11, the air cushion layer prevents the substrate 8 from directly contacting the turning arc surface 11, effectively preventing the substrate 8 from sticking to the turning arc surface 11, thereby avoiding phenomena such as paper breakage, film breakage, and creases, and improving product quality and production speed.

[0026] The static pressure chamber 12 is D-shaped.

[0027] The two ends of the steering housing 1 are fixed by the connecting seat 71. The connecting seat 71 allows the steering gear to rotate at a certain angle, allowing the on-site installation error to be adjusted, and ensuring that the feeding and discharging angles of the substrate 8 are consistent with the design.

[0028] Nozzle 2 is made of sheet metal and has a shell structure with an internal pressure chamber, which helps to ensure even airflow.

[0029] In order to improve the uniformity of air outlet, the bottom array of nozzle 2 is provided with several second air inlets 26, which allow the air in the static pressure chamber 12 to enter the interior of nozzle 2 evenly.

[0030] To further improve the uniformity of airflow from the outlet, thereby enhancing the stability and reliability of the air cushion layer, an air supply duct 3 is also included. The air supply duct 3 is fixed to the bottom of the static pressure chamber 12 and is positioned opposite the nozzle 2. The air supply duct 3 is square-shaped, and one or more surfaces of the air supply duct 3 within the static pressure chamber 12 are arrayed with several first ventilation holes, allowing communication between the static pressure chamber 12 and the air supply duct 3. An air inlet 18 is located at one end of the air supply duct 3. The first ventilation holes are used to uniformly deliver air into the static pressure chamber 12, thereby improving the uniformity and stability of the airflow from the outlet.

[0031] To facilitate the formation of an air cushion layer, the top of the nozzle 2 is provided with a first air outlet plate 21 and a second air outlet plate 22. The second air outlet plate 22 is located on both sides of the first air outlet plate 21, and the first air outlet plate 21 is located above the second air outlet plate 22 to form a stepped structure. An air outlet slit 25 is provided on the second air outlet plate 22, and an air outlet hole 24 is provided on the first air outlet plate 21. The air outlet slit 25 is also located on one side of the first air outlet plate 21, so that a stable air cushion layer is formed between the substrate 8 and the first air outlet plate 21, that is, a stable air cushion layer is formed from both sides of the first air outlet plate 21. In conjunction with the air outlet hole 24 on the first air outlet plate 21, air is continuously injected into the middle and both sides of the first air outlet plate 21, and the air cushion layer is stable.

[0032] The top of the nozzle 2 is provided with a first connecting plate 23 on both sides. The first connecting plate 23 is also located below the second air outlet plate 22 to form a stepped structure. The first connecting plate 23 is provided on the mounting hole 13, and the second air outlet plate 22 is located above the turning arc surface 11 so that an air storage groove 10 is formed between two adjacent nozzles 2. The air storage groove 10 is used to store air and form a stable air cushion layer.

[0033] To reduce the leakage of gas from the air cushion layer, a side baffle 5 is also included. The side baffle 5 is set at both ends of the air storage tank 10 and is slightly lower than the second air outlet plate 22. The side baffle 5 stabilizes both ends of the air cushion layer and keeps the edges of the substrate 8 stable and does not vibrate.

[0034] To further improve the stability of the air cushion layer, a baffle plate 4 is also included. The baffle plate 4 is located on both sides of the turning arc surface 11, so that the nozzle 2 is located between the two baffle plates 4. The baffle plate 4 can reduce the loss of air in the air cushion layer, effectively prevent a large amount of air from overflowing from the air cushion layer, ensure the stability of the air cushion pressure, and keep the edge of the substrate 8 stable and free from vibration. The baffle plate 4 is arranged radially along the turning arc surface 11, that is, parallel to the nozzle 2, so that the air in the air cushion layer can only be discharged through the two ends of the turning arc surface 11. Since the length of the two ends of the turning arc surface 11 is much smaller than the length of the two sides of the turning arc surface 11, the gas loss can be greatly reduced, and the gas discharge can be made continuous and stable, so that the pressure of the air cushion layer is stable and reliable, and no wrinkles appear on the surface of the substrate 8.

[0035] The blower 6 delivers air into the air supply pipe 3 of the air-float steering unit. The first ventilation hole on the air supply pipe 3 serves as the first air distribution point. After the air is distributed through the first ventilation hole on the air supply pipe 3, it is delivered into the static pressure chamber. In the static pressure chamber 12, the air is distributed a second time through the second air inlet 26 at the bottom of the nozzle 2. After being distributed, the air enters the pressure chamber inside the nozzle 2. The air is distributed a third time through the air outlet and then enters the space between the substrate 8 and the steering arc surface 11. The baffles 4 on both sides of the nozzle 2 prevent air from overflowing from the sides, and the side baffles 5 prevent air from overflowing from both ends of the steering arc surface 11. These measures ensure that the air forms a uniform air cushion layer with uniform pressure and wind speed between the air-float steering unit and the substrate 8, stably supporting the substrate 8, solving the problems of wrinkles and edge vibration of the substrate 8, and adapting to various widths.
