[0017] Reference Figures 1 to 4As shown in the figure, the present utility model provides an air floating support device at the connection between the air knife and the ULB of a cleaning machine, comprising: an air floating support assembly 2 and a vertical plate 6. Symmetric air floating holes 3 are provided in the middle of the upper surface of the air floating support assembly 2, and vertical plates 6 are symmetrically connected to both ends of the upper surface of the air floating support assembly 2. A flow dividing groove 12 is provided inside the air floating support assembly 2, and a flow dividing pipe 10 is fixedly connected to the lower surface of the air floating support assembly 2 through a fixing block 11. The flow dividing pipe 10 communicates with the flow dividing groove 12. At the same time, the flow dividing pipe 10 is connected to the air delivery pipe of a blower 4 through a connecting piece, and a speed regulating throttle valve 5 is fixedly connected to the middle of the air delivery pipe. A moving groove is provided inside the vertical plate 6, and an adjusting screw rod 7 is movably connected to the moving groove through a bearing. A moving block 8 is slidably connected to the moving groove through the adjusting screw rod 7 connected by screwing. At the same time, an infrared sensor 1 is fixedly connected to the surface of the moving block 8 through a groove.
[0018] In this embodiment, the air floating support assembly 2 is installed at the connection between the AK section of the air knife and the ULB of the cleaning machine. The switch of the blower 4 is turned on, and the blower 4 injects external air flow into the flow dividing groove 12 through the air delivery pipe and the flow dividing pipe 10. The external air flow in the flow dividing groove 12 will be evenly ejected through the air floating holes 3, so that when the glass moves above the device, the air flow ejected from the air floating holes 3 will enhance the suspension stability when the glass passes by. When the glass passes above the device, the tail of the glass is prone to bend downward due to the action of gravity, so that the infrared sensor 1 can detect it. The infrared sensor 1 will send a signal to an external PLC central control system (not shown in the figure) connected electrically. The PLC central control system will start the speed regulating throttle valve 5 to adjust the air flow output by the blower 4 accordingly, and then the intensity of the air flow ejected from the air floating support assembly 2 through the air floating holes 3 can be enhanced, so that the suspension height of the glass tail can be increased. When the infrared sensor 1 cannot detect the glass tail, the infrared sensor 1 will stop sending signals to the PLC central control system, and the PLC central control system will also stop the adjustment action of the speed regulating throttle valve 5, thus being able to avoid the probability of accidental scratching of the glass tail. At the same time, when it is necessary to adjust the warning height when the glass passes by, the adjusting screw rod 7 is rotated, and the adjusting screw rod 7 can drive the corresponding infrared sensor 1 to move in the vertical plane through the moving block 8 connected by screwing, so as to improve the flexibility of adjusting the warning height of the device.

[0022] In this embodiment, if Figure 2 and Figure 3 The setting of the diversion pipe 10 allows the airflow output by the blower 4 to be evenly injected into the diversion groove 12, thereby enhancing the stability of the airflow ejected from each flotation hole 3 and facilitating the uniform and stable adjustment of the intensity of the airflow ejected from each flotation hole 3.

[0026] In this embodiment, if Figure 2 and Figure 3 The buffer layer 9 is made of colorless silicone material, which enhances the elasticity of the upper surface of the air-floating support component 2. When the glass passes by, the tail of the glass moves downward excessively due to gravity, which can effectively reduce the chance of scratches caused by the tail of the glass hitting the surface of the air-floating support component 2, thereby helping to enhance the protective effect of the air-floating support device on the passing glass.
