[0002] In the lithium battery production process, after the substrate is coated, the coating on the substrate needs to be dried. During drying, the substrate enters the drying oven of the coating machine, and the surface of the substrate is blown by the air nozzles inside the drying oven. The hot air evaporates the moisture in the coating on the substrate.
[0003] However, the air outlet direction of the nozzles used in the existing coating machine ovens is fixed. When the substrate vibrates, it may cause the electrode to wrinkle. The existing oven nozzles can only improve the phenomenon of severe substrate vibration by frequently adjusting the tension, air frequency and belt speed, and the improvement effect is poor.

Detailed Implementation
[0026] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.
[0027] Reference Figures 1 to 5 This utility model provides an adjustable air outlet nozzle, including an air box 100 and an air guide 200. The air box 100 has an air inlet 110 at the top and an air outlet 120 at the bottom. The air guide 200 is rotatably connected to the air outlet 120 of the air box 100. An air guide channel is provided inside the air guide 200. One end of the air guide channel is connected to the air outlet 120, and the other end of the air guide channel is located on the radial side of the air guide 200. When the electrode sheets in the drying oven vibrate, the air outlet angle can be adjusted by rotating the air guide 200, thereby avoiding wrinkling of the electrode sheets and ensuring the drying quality of the electrode sheets.
[0028] In some preferred embodiments, the air outlet 120 has an elongated shape, with its length extending along the width of the electrode. The elongated shape of the air outlet 120 can provide uniform airflow, ensuring that the airflow can evenly cover all positions of the electrode in the width direction, effectively reducing temperature differences on the electrode surface, thereby improving drying efficiency and quality.
[0029] In some preferred embodiments, the air guide 200 includes a rotating shaft 210 and two air guide plates 220 disposed on one radial side of the rotating shaft 210. The two ends of the rotating shaft 210 are rotatably connected to the two sides of the air box 100. A locking member 230 is provided between the rotating shaft 210 and the air box 100. An inner cavity is provided inside the rotating shaft 210, which extends through both radial sides of the rotating shaft 210. An air guide channel is formed between the two air guide plates 220. The inner cavity connects the air outlet 120 and the air guide channel.
[0030] Understandably, the airflow enters the inner cavity of the rotating shaft 210 from the air outlet 120 of the bellows 100, and then blows onto the surface of the electrode through the air guide channel. When it is necessary to adjust the air outlet angle of the air guide channel, the locking member 230 is released, and then the rotating shaft 210 is rotated. The rotating shaft 210 drives the two air guide plates 220 to swing at a certain angle. Finally, the locking member 230 locks the rotating shaft 210 onto the bellows 100, thereby facilitating the adjustment of the air outlet angle.
[0031] It should be noted that the opening size of the rotating shaft 210 near the air outlet 120 is larger than the size of the air outlet 120. Moreover, during the rotation of the rotating shaft 210 within the adjustment range, the opening of the rotating shaft 210 near the air outlet 120 is always fully connected to the air outlet 120.
[0032] Furthermore, the two air guide plates 220 are parallel to each other, so that the cross-sectional area of the air guide channel remains unchanged, thereby keeping the airflow blown out through the air guide channel stable and further improving the drying quality of the electrode sheets.
[0033] Specifically, the locking component 230 is a locking bolt, and there are two locking bolts. The air box 100 has mounting holes 130 on both sides, and the rotating shaft 210 has threaded holes 211 at both ends. During installation, the locking bolts pass through the mounting holes 130 and are threaded into the threaded holes 211. By turning the locking bolts, the tightness of the rotating shaft 210 can be adjusted, thereby further facilitating the angle adjustment of the air guide component 200 and improving work efficiency.
[0034] Furthermore, a semi-circular groove 140 is provided at the air outlet 120, and the rotating shaft 210 is located in the semi-circular groove 140.
[0035] It is understandable that by setting the semi-circular groove 140, the outer surface of the rotating shaft 210 remains in contact with the semi-circular groove 140 during the rotation of the rotating shaft 210, thereby preventing air leakage and ensuring the sealing between the rotating shaft 210 and the bellows 100.
[0036] In some preferred embodiments, there are two air outlets 120 and two air guides 200. The two air outlets 120 are located on the bottom sides of the air box 100, and the two air outlets 120 are arranged sequentially along the conveying direction of the electrode. The airflow in the air box 100 can be blown to the surface of the electrode through the two air guides 200, which can improve the drying efficiency.
[0037] In some preferred embodiments, the bellows 100 is provided with fixing plates 150 on both sides, and the fixing plates 150 are provided with scale lines 151 distributed in a semi-circular arc shape. The two ends of the rotating shaft 210 are provided with pointers 240, and the pointers 240 correspond to the scale lines 151.
[0038] Understandably, when adjusting the angles of the two air guides 200, one of the rotating shafts 210 is rotated first. The rotating shaft 210 drives the pointer 240 to rotate a certain angle along the rotation center of the rotating shaft 210. Based on the value pointed to by the pointer 240 on the corresponding scale line 151, the other rotating shaft 210 is then rotated so that the pointers 240 on the two rotating shafts 210 point to the same value on the corresponding scale line 151. This ensures that the air outlet angles of the two air guides 200 are consistent, thereby improving the drying effect of the electrode sheets.
[0039] In some preferred embodiments, the bellows 100 is provided with three perforated plates 160. The three perforated plates 160 enclose a structure with an isosceles inverted triangle cross section. The airflow enters the bellows 100 from the air inlet 110 at the top of the bellows 100. The airflow first passes through the top perforated plate 160 and then through the other two perforated plates 160, which can make the airflow flow evenly to the two air outlets 120, thereby making it easier to control the airflow volume of the two air outlets 120.
[0040] Furthermore, the aperture of the top perforated plate 160 is larger than that of the other two perforated plates 160. The high-velocity airflow first passes through the top perforated plate 160, then through the larger-aperture perforated plate 160, and then through the other two smaller-aperture perforated plates 160. This allows for secondary depressurization of the high-velocity airflow, thereby ensuring a high consistency of airflow velocity on both sides of the nozzle.
[0041] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
