Description

Technical Field

[0001] This utility model relates to the field of air knife technology, specifically to an eagle-beak air knife. Background Technology

[0002] Existing traditional air knives are mostly one-piece designs, which easily accumulate dust and impurities inside, making them difficult to clean. After long-term use, the air outlet is prone to blockage, affecting service life and work efficiency. Secondly, their vertical air outlet direction results in low high-pressure air utilization and uneven airflow distribution, limiting the effectiveness of drying, cleaning and other scenarios. Furthermore, in some applications requiring cooling or blowing of plastic parts, the air knife outlet is very close to the workpiece, and liquid or solid substances easily condense at the air knife outlet. Liquid substances will drip onto the workpiece, and excessively rapid cooling will affect the molding and the quality of some workpieces. Solid substances will easily block the air knife outlet, resulting in uneven airflow from the air knife, leading to poor flatness and thickness of the produced products, which significantly affects the quality of the products. Therefore, it is necessary to propose the Eagle Beak Wind Blade. Utility Model Content

[0020] Example 2: As Figure 5 ; The difference between this embodiment 2 and embodiment 1 is that the eagle-beak air knife includes a lower blade body 1. Both ends of the lower blade body 1 have threaded holes 16 on their inner walls. The threaded holes 16 are used to connect the bolts on the sealing cover 3 and the sealing cover 4. The sealing cover 3 is installed on one end of the lower blade body 1 by bolts. A sealing gasket 5 is provided on the inner side of the sealing cover 3. The sealing cover 3 is sealed after installation by the sealing gasket 5. An air inlet hole 22 is provided on the inner wall of the sealing cover 3.

Threaded fastening or quick-release couplings are used to ensure no air leakage. It is recommended to add a filter system at the front end of the air source. Install a filter and oil-water separator to prevent impurities from clogging the air outlet 13. The eagle-beak air knife vents air from the side air outlet 13. The angle can be adjusted as needed by rotating the air knife or adjusting the screw connected to the threaded hole 18. If it is found to be unsuitable during debugging, readjust it until the air output is uniform. Air enters the lower blade body 1 through the side air duct 2. The air in the lower blade body 1 enters the air duct 23. Turn the corresponding hexagonal screw 7 and hexagonal screw 26 to adjust the size of the air outlet 13. The top of the air duct 23 is the eagle-beak type air outlet 13, through which air is discharged.

[0023] In summary, this novel eagle-beak air knife technology, through fluid dynamics optimization and modular design, significantly outperforms traditional air knives in energy efficiency, precision, and noise control, making it suitable for demanding industrial applications. The eagle-beak guide employs an asymmetrical oblique cut design, causing the airflow to diffuse in a fan shape, increasing the coverage area by over 40% and reducing energy loss, making it suitable for long-distance purging.
