Description

Technical Field

[0001] This utility model relates to the technical field of glass cleaning equipment, and in particular to an air knife for glass cleaning. Background Technology

[0002] Air knives are a crucial component of glass cleaning machines. Also known as air blades, air knives are made by directing air generated by the machine's fan through a duct into the air knife's cavity, then expelling it through its narrow outlet. The expelled air forms a thin, evenly distributed airflow along the length of the air knife, effectively removing any remaining moisture from the glass.

[0003] However, the size of the air outlet of existing air knives is generally fixed and cannot be adjusted according to the cleaning situation. Even if some air knives can adjust the size of the air outlet, they cannot perfectly adapt to various cleaning situations. Utility Model Content

The air outlets of the set of air knives are of different sizes. A set of air inlets are circumferentially distributed on the first rotating plate, and each air inlet is connected to a different air knife. The air inlet pipe is configured to cooperate with the set of air inlets.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are 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 are not intended to indicate or imply that the device or component 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.

[0017] like Figure 1 As shown, the present invention provides an air knife for glass cleaning, including a mounting frame 1. The mounting frame 1 includes two mounting plates 1.1, which are connected and fixed to the frame of the glass cleaning machine. The two mounting plates 1.1 are connected and fixed by a set of fixing rods 1.2.

[0018] An air inlet pipe 2 is connected to one side of the mounting bracket 1. The fan exhausts air into the air inlet pipe 2. A through hole 1.5 is provided on one of the mounting plates 1.1, and the through hole 1.5 connects to the air inlet pipe 2.

[0019] The air knife assembly 3 is rotatably connected within the mounting bracket 1. The air knife assembly 3 includes a first rotating plate 4 and a second rotating plate 5. Annular grooves 1.3 are provided on the opposite sides of the two mounting plates 1.1. An annular plate 1.4 is slidably connected within each annular groove 1.3. The two annular plates 1.4 are respectively connected to the first rotating plate 4 and the second rotating plate 5. When the first rotating plate 4 and the second rotating plate 5 rotate, the annular plate 1.4 rotates and is guided within the annular groove 1.3, making the rotation of the first rotating plate 4 and the second rotating plate 5 more stable.

[0020] A set of circumferentially distributed air knives 9 are connected between the first rotating plate 4 and the second rotating plate 5. The air outlets of the set of air knives 9 are of different sizes. A set of air inlets 6 are circumferentially distributed on the first rotating plate 4. The through hole 1.5 is on the rotation trajectory of the set of air inlets 6. The first rotating plate 4 drives the set of air inlets 6 to rotate. After determining the required air knife 9, the corresponding air inlet 6 is aligned with the through hole 1.5. Each air inlet 6 is connected to a different air knife 9, so that the air in the air inlet pipe 2 can enter the corresponding air knife 9 through the air inlet 6.

[0021] A drive device 7 is connected to the mounting bracket 1. The drive device 7 is used to drive the first rotating plate 4 to rotate. In this embodiment, the drive device 7 is a drive motor, which is an existing servo motor with a self-locking function. The drive motor is connected to the mounting plate 1.1. A through hole is provided on the corresponding mounting plate 1.1. The output shaft of the drive motor passes through the through hole. A second gear 8 is connected to the output shaft of the drive motor. In this embodiment, the first rotating plate 4 is the first gear. The second gear 8 meshes with the first gear. The drive motor drives the second gear 8 to rotate. The second gear 8 meshes with the first gear. The first gear drives a set of air blades 9 to rotate. When the corresponding air blade 9 is connected to the through hole 1.5, the air outlet will be set upward. The air in the air inlet pipe 2 enters the air blade 9 and is then discharged from the air outlet above.

[0022] This device clearly indicates the application of each air knife 9 during use. When encountering a corresponding application situation, the appropriate air knife 9 is selected. It is simple, clear, fast, and convenient, and can adapt to various cleaning situations to the greatest extent, thereby improving the cleaning effect.
