For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] The first embodiment of the utility model provides a wind valve structure, referring to Figure 1 The air valve structure is used to be arranged on the air nozzle, and the air nozzle includes an air nozzle body 1, and the air nozzle body 1 has an air inlet 11; the air valve structure includes an adjusting blade 2, and the adjusting blade 2 is rotatably and adjustably installed on the air nozzle body 1 and is located at the air inlet 11 to adjust the opening of the air inlet 11.

[0041] In the above structure, the adjusting blade 2 is used to adjust the opening area of ​​the air inlet 11, and then adjust the air intake of the air nozzle. During the drying process of the electrode, when the suspension state of the electrode at a certain position is unstable, the position with unstable suspension state can be adjusted to a stable state by adjusting the air intake of the air nozzle at the corresponding position, thereby improving the drying effect of the electrode. In addition, the opening area of ​​the air inlet 11 of the air nozzle body 1 can also be adjusted according to the wind force required by different types of electrodes, so as to meet various production needs.

[0042] Optionally, the nozzle body 1 may be formed by connecting and splicing a plurality of side panels in sequence, or may be an integrally formed structure, which is not limited here.

[0043] In this embodiment, the rotation axis of the adjusting blade 2 is located between the adjusting blade 2 and the air inlet 11 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.

[0044] Furthermore, the air nozzle also includes an adjusting shaft 3, which is rotatably connected to the air nozzle 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.

[0045] On the basis of the above structure, at least one end of the adjustment shaft 3 passes through the nozzle body 1. The portion of the adjustment shaft 3 passing through the nozzle 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 nozzle body 1. The operation slot 31 is used for inserting tools such as screwdrivers, and can be in a straight or cross shape, etc., to further facilitate the rotation of the adjustment shaft 3.

[0046] Reference Figure 2 and Figure 3 , a mounting groove 211 is concavely provided on the adjusting blade 2, and the adjusting shaft 3 is arranged in the mounting groove 211. On the basis of the above structure, a fixing plate 6 is arranged at the notch of the mounting groove 211, and the fixing plate 6 is connected to the adjusting blade 2 and the adjusting shaft 3. In this embodiment, a clamping groove 33 is arranged on the circumferential surface of the adjusting shaft 3, and the fixing plate 6 is clamped in the clamping groove 33; the middle position of the fixing plate 6 is connected to the adjusting shaft 3 by a locking member such as a screw, and the two sides of the fixing plate 6 are respectively connected to the adjusting blade 2 by locking members.

[0047] The adjusting blade 2 and the adjusting shaft 3 are connected to form a whole through the fixing plate 6, so as to ensure that the adjusting blade 2 and the adjusting shaft 3 can move synchronously.

[0048] In order to improve the connection strength between the adjusting blade 2 and the adjusting shaft 3 , there may be multiple fixing plates 6 , and the multiple fixing plates 6 are sequentially distributed along the axial direction of the adjusting shaft 3 .

[0049] Reference Figure 3 and Figure 4 The adjusting blade 2 includes a blade body 21 and two bending plates 22 respectively arranged on opposite sides of the blade body 21, and each bending plate 22 has an obtuse angle with the blade body 21. The setting of the bending plates 22 alleviates the problem of the adjusting blade 2 colliding with the two sides of the air inlet during the rotation process, avoids the phenomenon that the edge of the air inlet blocks the rotation of the adjusting blade 2, and makes the rotation of the adjusting blade 2 smoother. In addition, the setting of the bending plates 22 on both sides of the blade body 21 can also improve the overall structural strength of the adjusting blade 2, and alleviate the problem that the two side edges of the adjusting blade 2 are prone to shaking under the action of wind.

[0050] Furthermore, a mounting groove 211 is recessed in the middle of the blade body 21 , and the bottom of the mounting groove 211 can be set as a plane to prevent the adjustment shaft 3 from rotating relative to the adjustment blade 2 , thereby further improving the connection strength between the adjustment blade 2 and the adjustment shaft 3 .

[0051] Reference Figure 5 , an angle identification structure 5 may be provided on the outer side of the nozzle 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 11. In this embodiment, the angle identification structure 5 is an annular sheet, which can be fixed to the nozzle body 1 by screw connection or adhesive connection.

[0052] As an optional embodiment, refer to Figure 6 The air nozzle further comprises a locking assembly 4, which is mounted on the air nozzle body 1 and is used to lock or release the adjustment shaft 3. The locking assembly 4 can prevent the adjustment shaft 3 from rotating automatically, ensuring that the opening of the air inlet 11 of the air nozzle will not change at will.

[0053] Furthermore, the locking assembly 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 nozzle body 1, and the locking seat 41 and the nozzle body 1 can be fixedly connected by screw connection or welding; the ball plunger 42 can be mounted on the locking seat 41 by screw connection or interference fit, and the telescopic end of the ball plunger 42 faces the adjustment shaft 3;

[0054] 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 .

[0055] When the opening of the air inlet 11 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.

[0056] 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 assembly 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.

[0057] 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.

[0058] As another optional embodiment, refer to Figure 7 The air nozzle further comprises a driving source 7, which is mounted on the air nozzle body 1, and the output end of the driving source 7 is connected to the adjusting shaft 3. Specifically, the driving source 7 can be a motor, which is fixed on the air nozzle body 1 through a mounting seat; the output shaft of the motor passes through the upper plate of the mounting seat and is connected to one end of the adjusting shaft 3. When it is found that the suspension state of a certain position of the pole piece is unstable, the user can adjust the air inlet 11 of the air nozzle to a suitable opening by controlling the start and stop of the driving source 7, so that each position of the pole piece is in a stable suspension state.

[0059] The second aspect of the present invention provides a drying device, which includes the air valve structure provided by any of the above embodiments. Due to the provision of the air valve structure, when the drying device is drying the electrode, each position of the electrode is in a stable suspension state, thereby improving the overall suspension stability of the electrode and the drying effect of the electrode.

[0060] The drying device comprises a frame, and the air nozzle is mounted on the frame; an angle identification structure 5 can be mounted at a convenient position on the frame, and the angle identification structure 5 is arranged around the circumference of the adjustment shaft 3.
