[0034] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0036] It should be noted that in the description of the present invention, the terms "connection" and "installation" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through an intermediate medium; it can be a mechanical connection or an electrical connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] The first embodiment of the utility model provides an air nozzle air inlet member with a wind equalization function, referring to Figure 1 The air inlet of the air nozzle includes an air inlet body 1, on which a plurality of air outlets 11 are opened. The opening area of ​​the plurality of air outlets 11 decreases from the air inlet end of the air inlet body 1 to the closed end of the air inlet body 1.

[0038] In the above structure, the wind speed at the air outlet 11 with a larger opening area is slower, and correspondingly, the wind pressure in the area with slower wind speed is smaller. During the operation of the air nozzle air inlet provided by the utility model, wind enters the inner cavity of the air nozzle air inlet from the air inlet 12 of the air nozzle air inlet. Since the fan continuously supplies air, the wind pressure at the air inlet end of the air nozzle air inlet is greater than the wind pressure at the closed end of the air nozzle air inlet. In view of this situation, the opening area of ​​the multiple air outlets 11 on the air nozzle air inlet provided by the utility model tends to decrease from the air inlet end of the air inlet body 1 to the closed end of the air inlet body 1, thereby reducing the pressure difference of the wind blown out from the two ends of the air inlet body 1, making the wind pressure of the wind blown out from each area of ​​the air nozzle air inlet relatively uniform, thereby improving the stability of the pole piece suspension and the drying effect of the pole piece.

[0039] The air inlet of the air nozzle provided by the utility model can make the wind pressure of the wind blown out of each area of ​​the air inlet of the air nozzle relatively uniform by only changing the size of the opening area of ​​the air outlet 11, and has the advantages of simple structure, significant effect and low cost.

[0040] Optionally, the air inlet member body 1 can be formed by splicing a plurality of side panels which are connected end to end in sequence, or can be formed in one piece, which is not limited here.

[0041] Continue to refer to Figure 1 As an optional embodiment, multiple air outlets 11 are distributed in an array to form multiple groups of air outlets distributed sequentially from the air inlet end of the air inlet body 1 to the closed end of the air inlet body 1; the apertures of the air outlets 11 in each air outlet group are the same, and the apertures of the multiple air outlet groups decrease from the air inlet end of the air inlet body 1 to the closed end of the air inlet body 1. Specifically, the air outlets 11 in each air outlet group are distributed sequentially along the width direction of the air nozzle air inlet, and the multiple air outlet groups are distributed sequentially along the length direction of the air nozzle air inlet to form an array structure.

[0042] As another optional embodiment, refer to Figure 2 , the air outlet 11 is a long hole structure; the length directions of the multiple air outlets 11 are parallel, and the multiple air outlets 11 are distributed side by side. Specifically, the length direction of the air outlet 11 is parallel to the width direction of the air inlet body 1, and the multiple air outlets 11 are distributed in sequence along the length direction of the air inlet body 1 to form an exhaust air outlet 11. In this embodiment, the width of the multiple air outlets 11 decreases from the air inlet end of the air inlet body 1 to the closed end of the air inlet body 1.

[0043] The structures of the two air outlets 11 described above can both make the wind pressure of the air outlets in each area of ​​the air inlet of the air nozzle relatively uniform, thereby improving the stability of the pole piece suspension and the drying effect of the pole piece.

[0044] Reference Figure 3 , the cross-sectional area of ​​the inner cavity of the air inlet body 1 decreases from the air inlet end of the air inlet body 1 to the closed end of the air inlet body 1. In this embodiment, the side wall of the air inlet body 1 facing the pole piece is arranged horizontally, and an air outlet 11 is arranged on it; the side wall of the air inlet body 1 away from the pole piece is inclined downward from the air inlet end of the air inlet body 1 to the closed end of the air inlet body 1. The above arrangement can reduce the pressure difference between the air inlet end and the closed end of the air inlet body 1, and further improve the uniformity of the wind pressure at each air outlet 11.

[0045] Reference Figure 4 and Figure 5The air nozzle air inlet member provided by the utility model also includes an adjusting blade 2, which is rotatably and adjustably mounted at the air inlet 12 of the air inlet member body 1. The adjusting blade 2 is used to adjust the opening area of ​​the air inlet 12, thereby adjusting the air intake volume of the air nozzle air inlet member. During the drying process, when the suspension state of the electrode piece at a certain position is unstable, the position where the suspension state is unstable can be adjusted to a stable state by adjusting the air intake volume of the air nozzle air inlet member at the corresponding position, thereby improving the drying effect of the electrode piece.

[0046] In this embodiment, the rotation axis of the adjusting blade 2 is located between the adjusting blade 2 and the air inlet 12 to improve the stability of the adjusting blade 2 during rotation. It is understandable that the rotation axis of the adjusting blade 2 can also be located on one side of the adjusting blade 2.

[0047] Furthermore, the air inlet of the air nozzle also includes an adjusting shaft 3, which is rotatably connected to the air inlet body 1, and the adjusting blade 2 is mounted on the adjusting shaft 3. Optionally, the adjusting blade 2 and the adjusting shaft 3 can be fixedly connected by means of screw connection, clamping connection, gluing, etc., so that the two can rotate synchronously.

[0048] On the basis of the above structure, at least one end of the adjustment shaft 3 passes through the air inlet body 1. The portion of the adjustment shaft 3 passing through the air inlet body 1 can be used for subsequent manual rotation for adjustment. In order to further facilitate operation, an operation slot 31 is provided on the end surface of the end of the adjustment shaft 3 passing through the air inlet body 1. The operation slot 31 is used for inserting tools such as a screwdriver, and can be in a straight shape or a cross shape, etc., to further facilitate the rotation of the adjustment shaft 3.

[0049] Reference Figure 6 The air inlet of the air nozzle also includes a locking structure 4, which is installed on the air inlet body 1 and is used to lock or release the adjustment shaft 3. The locking structure 4 can prevent the adjustment shaft 3 from rotating automatically, ensuring that the opening of the air inlet 12 of the air inlet of the air nozzle will not change at will.

[0050] As an optional embodiment, the locking structure 4 includes a locking seat 41 and a ball plunger 42 mounted on the locking seat 41, wherein: the locking seat 41 is mounted on the air inlet body 1, and the locking seat 41 and the air inlet body 1 can be fixedly connected by screwing or welding; the ball plunger 42 is mounted on the locking seat 41, and the telescopic end of the ball plunger 42 faces the adjustment shaft 3;

[0051] A plurality of locking grooves 32 are arranged on the outer circumference of the adjusting shaft 3 , and the telescopic end of the ball plunger 42 can be inserted into one of the locking grooves 32 .

[0052] When the opening of the air inlet 12 needs to be adjusted, torque is applied to the adjusting shaft 3 to make the telescopic end of the ball plunger 42 disengage from the corresponding locking groove 32; when the adjusting shaft 3 is rotated to the set position, the telescopic end of the ball plunger 42 is inserted into the locking groove 32 at the corresponding position to lock the adjusting shaft 3 to prevent the adjusting shaft 3 from rotating on its own.

[0053] In the above structure, the plurality of locking grooves 32 are evenly distributed along the circumferential direction of the adjusting shaft 3, and the angle between the line connecting two adjacent locking grooves 32 and the axis of the adjusting shaft 3 can be 5°, 10°, 15°, 30°, etc. When the user rotates the adjusting blade 2, the locking structure 4 will lock the adjusting shaft 3 every time the adjusting shaft 3 rotates a certain angle, and the user can clearly perceive the rotation angle of the adjusting blade 2, thereby improving the convenience of adjustment.

[0054] Furthermore, the number of the ball plungers 42 can be multiple, and the multiple ball plungers 42 are arranged around the circumference of the adjustment shaft 3 to lock different positions of the adjustment shaft 3 and improve the locking force of the adjustment shaft 3. The number of the ball plungers 42 can be the same as the number of the locking grooves 32, or different, and can be adjusted according to the actual use requirements.

[0055] Reference Figure 7 , an angle identification structure 5 may be provided on the outside of the air inlet body 1, and the angle identification structure 5 is arranged around the circumference of the adjustment shaft 3. During the adjustment process, the user can understand the rotation position of the adjustment blade 2 through the angle identification structure 5, and then know the opening of the air inlet 12. In this embodiment, the angle identification structure 5 is an annular sheet, which can be fixed to the air inlet body 1 by screw connection or adhesive connection.

[0056] The second aspect of the present invention provides a drying device, which includes a nozzle air inlet with a wind distribution function provided by any of the above embodiments. Due to the provision of the nozzle air inlet with a wind distribution function, the wind pressure on each position of the pole piece during the drying process of the pole piece by the drying device is relatively uniform, thereby improving the stability of the pole piece suspension and the drying effect of the pole piece.

[0057] The drying device comprises a frame, and the air inlet of the air nozzle is installed on the frame; an angle identification structure 5 can be installed at a convenient position on the frame, and the angle identification structure 5 is arranged around the circumference of the adjustment shaft 3. The user can know the opening of the air inlet 12 through the angle identification structure 5 during the adjustment process.

[0058] A third aspect of the present invention provides a coating device, which includes the above-mentioned drying device.

[0059] The drying device and coating equipment provided by the utility model at least have all the technical effects of the above-mentioned air nozzle air inlet member, which will not be described in detail here.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
