Description

Technical Field

[0001] This utility model relates to the field of pneumatic suspension technology, specifically to an air-floating air knife nozzle. Background Technology

[0002] During oven baking, to avoid scratching the substrate surface, air suspension is used without contact with the substrate. This involves using upper and lower air knives for balanced air blowing, hence the name air-floating oven. In existing technology, air-floating ovens often use welded air knife nozzles. For wide substrates (e.g., 2-meter wide substrates), the structure needs to be expanded to accommodate the substrate size. However, with increased structural size, the deformation at the weld joints of the welded air knife can become uncontrollable, affecting the uniformity of airflow and thus impacting the quality of the substrate. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide an air-floating air knife nozzle to solve the problem that the welding air knife nozzle mentioned in the background art is not suitable for wide substrates.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is an air-floating air knife nozzle, comprising:

[0005] The nozzle body extends along a first direction. A left nozzle plate and a right nozzle plate extending along the first direction are symmetrically arranged on both sides of the nozzle body along a second direction.

[0006] Both the left and right sides of the nozzle have bent portions at their bottom along the third direction. The bent portions are bent along the second direction toward the nozzle body to cooperate with the nozzle body to form an air outlet.

[0007] Multiple internal threaded studs are respectively disposed at both ends of the nozzle body along the second direction and spaced apart along the first direction. Each internal threaded stud extends along the second direction and is used to connect the left side plate and the right side plate of the nozzle to the nozzle body. The first direction, the second direction, and the third direction are perpendicular to each other.

[0008] This utility model provides an air-floating air knife nozzle, which connects the left and right sides of the nozzle to the nozzle body using multiple internal threaded studs. This bolt-fixed structure replaces the welding fixation used in existing technologies, ensuring stability and reliability during operation and avoiding welding deformation problems. The left and right sides of the nozzle are fixed to both ends of the nozzle body by internal threaded studs. The distance between the left and right sides of the nozzle and the nozzle body can be adjusted by changing the length of the internal threaded studs, thus accommodating wide substrates.

[0009] In some embodiments, the air-floating air knife nozzle further includes a cover plate extending along the first direction. The nozzle body is hollow and has an opening at the top; the cover plate is disposed at the top of the nozzle body to close the opening.

[0010] By adopting the above technical solution, the overall size of the air knife nozzle will also increase to accommodate the wide substrate. By making the nozzle body hollow to reduce weight, the thickness of the plate is reduced to a minimum while ensuring performance. The internal space of the nozzle body is sealed by a cover plate to reduce the entry of external pollutants, improve the cleanliness of the nozzle and maintain the stability of the internal airflow.

[0011] In some embodiments, the air-floating air knife nozzle further includes a mesh plate extending along the first direction and disposed above the cover plate. The two ends of the mesh plate along the second direction are respectively connected and fixed to the left side plate and the right side plate of the nozzle.

[0012] Using the above technical solution, the surface of the mesh plate is densely covered with holes, which can disperse the incoming air, making the airflow more uniform and reducing the unevenness of airflow at the air outlet. At the same time, the mesh plate can also act as a protective layer to prevent large particles of impurities from directly entering the nozzle, reducing wear and clogging inside the nozzle.

[0013] In some embodiments, the bottom of the nozzle body is inclined at both ends along the second direction toward the third direction toward the cover plate to form an inclined portion.

[0014] By adopting the above technical solution, the inclined design helps to optimize the airflow distribution, allowing the airflow to be blown out of the nozzle more evenly, thereby improving the air flotation effect and drying efficiency. Furthermore, the inclined setting of the inclined section avoids the problem of uneven airflow caused by the nozzle blowing directly onto the substrate.

[0015] In some embodiments, the inclined portion and the bent portion, which are located on the same side along the second direction, have an included angle of 10° to 50° between their respective planes.

[0016] By adopting the above technical solution, the distribution and direction of airflow can be optimized by precisely controlling the angle between the inclined part and the bent part, so that the airflow is blown out of the nozzle more evenly, improving the air flotation effect and drying efficiency, thereby improving the performance of the air knife nozzle.

[0017] In some embodiments, the nozzle body has connecting assemblies at both ends along the first direction. Each connecting assembly includes a nozzle end plate and a hook plate. The nozzle end plate, the nozzle body, the left side plate, and the right side plate all have corresponding mounting holes. The hook plate is located on the side of the nozzle end plate away from the nozzle body along the first direction and is used to install a latch hook.

[0018] By adopting the above technical solution, the nozzle end plate and hook plate design enable quick installation and removal of the nozzle, facilitating maintenance and replacement. Furthermore, the mounting holes allow for bolt installation and fixation of the nozzle end plate, avoiding the use of welding connections.

[0019] In some embodiments, along the third direction, the mesh plate, the left side plate and the right side plate of the nozzle, the cover plate and the nozzle body are each provided with multiple bolt mounting holes at corresponding positions for fixed connection by bolts.

[0020] By adopting the above technical solution, the fixed connection method achieved through bolt mounting holes can enhance the connection stability between the mesh plate and the nozzle, reduce structural loosening caused by vibration or airflow impact, thereby improving the overall durability and reliability of the nozzle, and making the air knife nozzle a fully bolted fixed method, thus solving the welding deformation problem.

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0026] refer to Figure 1 and Figure 2 , Figure 1 An exploded view of the structure of an air-floating air knife nozzle 1 provided in an embodiment of the present invention is shown; Figure 2 A cross-sectional view of an air-floating air knife nozzle 1 provided in an embodiment of the present invention is shown.

[0027] like Figure 1 and Figure 2As shown, the technical solution adopted by this utility model is an air-floating air knife nozzle 1, including: a nozzle body 2 and a plurality of internal threaded studs 3, wherein the nozzle body 2 is along a first direction ( Figure 1 Extending along the second direction (as shown in the X direction). The nozzle body 2 extends along the second direction (as shown in the X direction). Figure 1 A nozzle left side plate 20 and a nozzle right side plate 21 extending along a first direction are symmetrically provided on both sides (as shown in the Y direction). The nozzle left side plate 20 and the nozzle right side plate 21 are along a third direction (as shown in the Y direction). Figure 1 The bottom of each nozzle body 2 (as shown in the Z-direction) is provided with a bent portion 22. The bent portion 22 is bent along the second direction towards the nozzle body 2 to form an air outlet 23 in conjunction with the nozzle body 2. Multiple internal thread studs 3 are respectively provided at both ends of the nozzle body 2 along the second direction and are spaced apart along the first direction. Each internal thread stud 3 extends along the second direction and is used to connect the left side plate 20 and the right side plate 21 of the nozzle to the nozzle body 2. The first direction, the second direction and the third direction are perpendicular to each other.

[0028] This utility model provides an air-floating air knife nozzle 1, which connects the left side plate 20 and the right side plate 21 of the nozzle to the nozzle body 2 by setting multiple internal threaded studs 3. This bolt-fixed structure replaces the welding fixation in the prior art, ensuring their stability and reliability during operation and avoiding welding deformation problems. The left side plate 20 and the right side plate 21 of the nozzle are fixed to both ends of the nozzle body 2 by the internal threaded studs 3. The distance between the left side plate 20, the right side plate 21, and the nozzle body 2 can be adjusted by changing the length of the internal threaded studs 3, thereby matching wide substrates.

[0029] In some embodiments, reference Figure 1 and Figure 2 The air-floating air knife nozzle 1 also includes a cover plate 4, which extends along a first direction. The nozzle body 2 is hollow and has an opening at the top. The cover plate 4 is located at the top of the nozzle body 2 to close the opening.

[0030] For example, in order to adapt to wide substrates, the overall size of the air knife nozzle will also be increased. By making the nozzle body 2 hollow to reduce weight, the thickness of the board is reduced to a minimum while ensuring performance. The internal space of the nozzle body 2 is sealed by the cover plate 4 to reduce the entry of external pollutants, improve the cleanliness of the nozzle and maintain the stability of the internal airflow.

[0031] In some embodiments, reference Figure 1 and Figure 2 The air-floating air knife nozzle 1 also includes a mesh plate 5, which extends along a first direction and is positioned above the cover plate 4. The two ends of the mesh plate 5 along a second direction are respectively connected and fixed to the left side plate 20 and the right side plate 21 of the nozzle.

[0032] For example, the surface of the mesh plate 5 is densely covered with mesh holes, which can disperse the incoming air, making the airflow more uniform and reducing the unevenness of airflow at the air outlet 23. At the same time, the mesh plate 5 can also act as a protective layer to prevent large particles of impurities from directly entering the nozzle, reducing wear and clogging inside the nozzle.

[0033] In some embodiments, reference Figure 1 and Figure 2 The bottom of the nozzle body 2 is inclined at both ends along the second direction towards the cover plate 4 in the third direction to form an inclined portion 24.

[0034] For example, the design of the inclined portion 24 helps to optimize the airflow distribution, allowing the airflow to be blown out of the nozzle more evenly, thereby improving the air flotation effect and drying efficiency. In addition, the inclined arrangement of the inclined portion 24 can avoid the problem of uneven airflow caused by the nozzle blowing directly onto the substrate.

[0035] In some embodiments, the inclined portion 24 and the bent portion 22 located on the same side along the second direction have an included angle of 10° to 50° between their respective planes.

[0036] For example, by precisely controlling the angle between the inclined portion 24 and the bent portion 22, the distribution and direction of the airflow can be optimized, so that the airflow is blown out of the nozzle more evenly, improving the air flotation effect and drying efficiency, thereby improving the performance of the air knife nozzle.

[0037] In some embodiments, reference Figure 1 and Figure 2 The nozzle body 2 has connecting components at both ends along the first direction. The connecting components include a nozzle end plate 25 and a hook plate 26. The nozzle end plate 25, the nozzle body 2, the left side plate 20, and the right side plate 21 are all provided with corresponding mounting holes 61. The hook plate 26 is located on the side of the nozzle end plate 25 away from the nozzle body 2 along the first direction and is used to install a latch hook.

[0038] For example, the design of the nozzle end plate 25 and the hook plate 26 allows for quick installation and removal of the nozzle, facilitating maintenance and replacement. Furthermore, the mounting hole 61 allows for bolt mounting of the nozzle end plate 25, avoiding the use of welding connections.

[0039] In some embodiments, reference Figure 1 and Figure 2 Along the third direction, the mesh plate 5, the left side plate 20 and the right side plate 21 of the nozzle, the cover plate 4 and the nozzle body 2 are all provided with multiple bolt mounting holes 60 at corresponding positions for fixed connection by bolts.

[0040] For example, the fixed connection method achieved through the bolt mounting holes 60 can enhance the connection stability between the mesh plate 5 and the nozzle, reduce structural loosening caused by vibration or airflow impact, thereby improving the overall durability and reliability of the nozzle, and making the air knife nozzle a fully bolted fixed method, solving the welding deformation problem.
