Description

Technical Field

[0001] This application relates to the field of battery processing technology, and in particular to an adjustable air nozzle, a drying assembly, and a drop-coating drying device. Background Technology

[0002] Drying the coating is a crucial step in the manufacturing process of battery electrodes. To ensure coating quality and performance, drying ovens are widely used. During electrode production, after the strip is slit, it may require dispensing, coating, or spraying with other substances, depending on process requirements. Following these steps, the strip undergoes unwinding and rewinding. After spraying between unwinding and rewinding, the strip must be dried to ensure coating uniformity and adhesion.

[0003] In existing drying technologies, most materials are dried as a whole. However, due to process requirements, some materials are dried only in certain areas. If the entire material is dried, the uncoated parts may crack, which will seriously affect the quality of the final product.

[0004] Therefore, there is an urgent need for a new solution that can achieve localized drying of the strip to avoid cracking of the coating on uncoated areas, thereby improving production efficiency and product quality. Utility Model Content

[0018] The limiting flange can contact and abut against the two sides of the clearance opening in the rotation direction of the air outlet to limit the rotation angle of the air outlet.

[0019] Furthermore, both the air outlet component and the fixed carrier are fan-shaped cylindrical shell structures;

[0020] The cylindrical surface of the air outlet forms the first mating curved surface, and its cut opening forms the air inlet;

In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0059] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0060] This application discloses an adjustable air nozzle.

[0061] Please see Figures 1 to 3 One embodiment of an adjustable air nozzle provided in this application includes:

[0062] Fixed carrier 1, air outlet 2 and adjustment component 3.

[0063] The air outlet 2 is provided with an air inlet 22 and an air outlet 21, and the air outlet 2 is rotatably mounted on the fixed carrier 1.

[0064] The adjustment component 3 is connected to the air outlet component 2 and is used to adjust the air outlet angle of the air outlet 21 by adjusting the rotation angle of the air outlet component 2 relative to the fixed carrier 1.

[0065] The adjustable air outlet designed in this application has the following beneficial effects:

[0066] 1. Achieving Localized Drying: Since the air outlet 2 is rotatably mounted on the fixed carrier 1, and the adjusting component 3 can adjust the rotation angle of the air outlet 2 relative to the fixed carrier 1, the air outlet angle of the air outlet 21 can be adjusted. This design allows for targeted drying of specific parts of the strip or the same strip with varying degrees of dryness, precisely controlling the drying area. For the same strip, it avoids the situation where over-drying of the entire strip during localized drying causes cracking of the coating in other parts, ensuring the integrity and quality of the strip coating, reducing the defect rate, and improving product quality.

[0067] 2. Compatible with different material strip specifications: By setting the number of adjustable air nozzles and coordinating the air outlet angles of different nozzles, the equipment can flexibly adjust the number and angle of air nozzles when dealing with production tasks of different quantities of material strips to meet the drying requirements of different sizes of material strips. This enhances the equipment's adaptability to different production conditions, improves production flexibility and versatility, and ultimately increases production efficiency.

[0068] 3. Comprehensive Improvement in Production Efficiency and Product Quality: On the one hand, it achieves localized drying of the material strip, ensuring product quality; on the other hand, it is compatible with different quantities and specifications of material strips, improving equipment versatility and production flexibility. These two factors work together to reduce rework caused by product quality issues and production delays due to equipment incompatibility, comprehensively improving production efficiency and product quality, and enhancing the overall benefits of the production process.

[0069] The above is an embodiment of an adjustable air nozzle provided in this application. The following is an embodiment of an adjustable air nozzle provided in this application. Please refer to the following for details. Figures 1 to 6 .

[0070] Based on the solution of Embodiment 1 above:

[0071] Furthermore, the air outlet 2 has a first mating surface, and the air outlet 21 is disposed on the first mating surface.

[0072] like Figure 3 As shown, the fixed carrier 1 has a cavity 11, and the air outlet 2 is rotatably installed in the cavity 11; the inner wall surface of the cavity 11 is a second mating surface that rotatably mates with the first mating surface.

[0073] By setting the first mating surface of the air outlet 2 and the second mating surface of the inner wall of the cavity 11 of the fixed carrier 1, a smooth rotational fit can be achieved between the air outlet 2 and the fixed carrier 1. This facilitates the flexible rotation of the air outlet 2 on the fixed carrier 1, and in actual use scenarios, the air outlet direction can be changed according to needs, improving the flexibility of air outlet and meeting the requirements of different users for airflow adjustment.

[0074] The design incorporates a recessed cavity 11 into which the air outlet 2 is rotatably mounted. The air supply duct assembly 62 only needs to be connected to the opening of the recessed cavity 11 to supply air to the cavity 11. The air then enters the air outlet 2 through the air inlet 22 and exits through the air outlet 21. This design allows the air supply duct assembly 62 to be connected only to a fixed carrier 1. Regardless of how the air outlet 2 rotates, the air supply process remains unaffected, ensuring a stable air supply to the air outlet 2. This significantly simplifies the installation process, reduces installation difficulty, improves the convenience and stability of the entire system installation, and reduces the potential instability in the air supply connection caused by the rotation of the air outlet 2.

[0075] like Figure 2 as well as Figure 4 As shown, the fixed carrier 1 is provided with a connecting cavity 11 and a clearance opening 12 that avoids the air outlet 21. The opening area of ​​the clearance opening 12 in the rotation direction of the air outlet 2 is larger than the opening area of ​​the air outlet 21 in the rotation direction of the air outlet 2. It can be understood that the overall opening size of the clearance opening 12 is larger than that of the air outlet 21, and it can avoid the air outlet 21 within a certain rotation angle range. This ensures that the clearance opening 12 can avoid the air outlet 21 at a certain rotation angle without obstructing it. When the air outlet 2 rotates to adjust the airflow direction, the airflow from the air outlet 21 is not affected, maintaining a good airflow effect, improving the user experience, and meeting the airflow requirements under different airflow adjustment angles.

[0076] Furthermore, such as Figure 2 as well as Figure 5 As shown, the air outlet 21 is provided with a limiting flange 23; the limiting flange 23 can contact and abut with the two sides of the clearance opening 12 in the rotation direction of the air outlet 2 to limit the rotation angle of the air outlet 2.

[0077] By setting a limiting flange 23, when the air outlet 2 rotates to a preset angle, the limiting flange 23 will contact and abut against the side of the clearance port 12, thereby preventing the air outlet 2 from continuing to rotate and playing a limiting role. This design avoids the problem of poor air outlet effect due to excessive rotation.

[0078] The limiting flange 23 can be a ring structure designed to surround the air outlet 21, or it can be two limiting blocks; there is no specific limitation.

[0079] Furthermore, such as Figure 4as well as Figure 5 As shown, both the air outlet 2 and the fixed carrier 1 are fan-shaped cylindrical shell structures. It can be understood that a fan-shaped cylindrical shell structure is a structure formed by cutting off a portion of a cylindrical shell structure along the axial direction. For example, a semi-cylindrical shell structure after cutting off half of it is a type of fan-shaped cylindrical shell structure.

[0080] The cylindrical surface of the air outlet 2 forms the first mating curved surface, and its cut opening forms the air inlet 22. The air outlet 21 is set along the axial direction of the air outlet 2 (designed as a long strip air outlet).

[0081] The inner cavity of the fixed carrier 1 forms a concave cavity 11, and the clearance opening 12 is set along the axial direction of the fixed carrier 1 (designed as a long strip opening).

[0082] This fan-shaped columnar shell structure design not only satisfies the nesting fit between the air outlet 2 and the fixed carrier 1, but also makes the air outlet 21 straight and parallel to the feeding direction, which is more convenient in terms of processing and assembly.

[0083] Of course, depending on actual needs, the air outlet 2 and the fixed carrier 1 can also be designed as a spherical shell structure, and there are no specific restrictions.

[0084] Furthermore, such as Figure 3 As shown, mounting flanges 14 are provided around the opening of the cavity 11.

[0085] The mounting flange 14 serves two purposes: firstly, it provides a mounting base for the fixed carrier 1, facilitating the connection and fixation of the fixed carrier 1 to the air supply duct assembly 62; secondly, it increases the structural strength of the fixed carrier 1 and improves the overall stability.

[0086] Furthermore, such as Figure 2 As shown, at least one end of the air outlet 2 is fixed with a rotating shaft; the rotating shaft is rotatably connected to the fixed carrier 1; at least one adjusting component 3 is connected to the rotating shaft.

[0087] The other end of the air outlet 2 can be provided with a shaft hole to rotate with the rotating structure on the fixed carrier 1, or it can be designed as a rotating shaft to rotate with the fixed carrier 1.

[0088] The adjustment component 3 can be an electric or manual mechanism. By driving the rotating shaft to rotate, the air outlet component 2 can be adjusted accordingly.

[0089] Furthermore, such as Figure 2 As shown, taking the manual mechanism design as an example, the adjustment component 3 includes a lever 31 and a locking component 32.

[0090] At least one end of a rotating shaft extends out of the fixed carrier 1 and is connected to a paddle 31 (the paddle 31 may be a paddle plate, which is fixed to the rotating shaft by welding or other means).

[0091] The fixed carrier 1 has a threaded hole 13 at the position corresponding to at least one rotating shaft; the locking member 32 passes through the threaded hole 13 and is threaded to the threaded hole 13; one end of the locking member 32 passing through the threaded hole 13 can abut against the rotating shaft to lock the rotation angle of the rotating shaft (the locking member 32 can be a locking screw / bolt / screw, and there is no specific limitation).

[0092] This manual mechanism design allows users to manually operate the lever 31 to drive the rotating shaft, thereby adjusting the angle of the air outlet 2. The lever 31 is intuitive and easy to operate; users can easily adjust the air outlet angle by simply toggling the lever 31. The locking element 32 ensures that the air outlet 2 remains stable after being adjusted to the desired angle. The locking element 32 engages with the threaded hole 13 on the fixed carrier 1 via a threaded connector. When the locking element 32 passes through the threaded hole 13 and abuts against the rotating shaft, it effectively prevents accidental rotation of the rotating shaft, thereby locking the rotation angle of the air outlet 2 and ensuring the accuracy and stability of the air delivery direction.

[0093] like Figure 6 As shown, this application also discloses a drying assembly, including a return air duct assembly 61, an air supply duct assembly 62, a return air nozzle 51, and at least one adjustable air outlet nozzle.

[0094] The return air nozzle 51 is arranged around the adjustable air outlet and connected to the return air duct assembly 61; the return air nozzle 51 has an array of return air holes 511 arranged on the return air surface to recover the hot air used for drying and maintain the hot air circulation.

[0095] Adjustable air outlet nozzle connection air supply duct assembly 62.

[0096] This design not only improves the utilization efficiency of hot air but also enhances the drying effect. The return air nozzle 51 surrounds the adjustable air outlet nozzle, ensuring that hot air can be evenly and effectively recycled, avoiding waste of hot air.

[0097] Furthermore, there are at least two adjustable air nozzles, which are arranged parallel to each other in a direction perpendicular to the feeding direction.

[0098] This setup allows multiple adjustable nozzles to operate simultaneously, drying different parts of the material strip and further improving drying efficiency and uniformity. Furthermore, by adjusting the air outlet angle of each nozzle, the drying area can be more precisely controlled to meet diverse drying needs.

[0099] like Figures 6 to 8 As shown, this application also discloses a drop coating drying apparatus, including a hot air device 8, an oven 72, and a drying component.

[0100] The oven 72 is equipped with a drying cavity; the two opposite sides of the oven 72 are respectively provided with a feed inlet 721 and a discharge outlet 722 that connect to the drying cavity, which facilitates the entry and exit of the material belt.

[0101] The top of the oven 72 is provided with a mounting port 723 for installing the drying component, which facilitates the installation of the drying component inside the oven 72. The oven 72 and the drying component are further integrated together by a casing 71, which further reduces heat loss and saves energy.

[0102] The hot air device 8 is connected to the air supply duct assembly 62 of the drying component to supply hot air and provide the necessary heat for the drying process.

[0103] The design of the drip coating drying device comprehensively considers multiple aspects such as drying efficiency, uniformity, and equipment maintenance, ensuring that the drip-coated material strip receives high-quality drying treatment. Simultaneously, by flexibly adjusting the number and angle of adjustable air nozzles in the drying assembly, it can adapt to production tasks involving different specifications and quantities of material strips, improving the equipment's versatility and production efficiency.

[0104] The above provides a detailed description of an adjustable air nozzle, drying assembly, and drip coating drying device provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
