Description

Technical Field

[0001] This utility model relates to the field of air nozzle direction adjustment technology, specifically to a deflection correction blade, an air nozzle, and an oven. Background Technology

[0002] In the field of lithium battery electrode coating, after the electrode coating is completed, it needs to be sent into an oven for drying. The oven has an inlet and an outlet at both ends. The electrode enters the oven through the inlet for drying, and the dried electrode exits through the outlet. However, due to the long length of the oven, the electrode may shift during the drying process.

[0003] To prevent electrode misalignment during the drying process, blade assemblies are often used to adjust the airflow at the outlet, addressing electrode misalignment under different conditions. Existing blade assemblies are typically driven by power components (such as servo motors), which, due to the limited space at the outlet and the large size of the driving components, result in a complex overall device structure. Utility Model Content

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] The following is combined Figures 1 to 15 The following describes embodiments of the present invention.

[0038] According to an embodiment of the present invention, in one aspect, a correction blade is provided, comprising: a blade assembly 3, adapted to be disposed within the receiving space of the air outlet 2 of the housing 1, the blade assembly 3 including an active blade 301, a connector 303 and a driven blade 302, the active blade 301 being connected to the driven blade 302 via the connector 303; and an adjustment assembly 4, the adjustment assembly 4 including a rotating screw 401 and a bushing 402, the bushing 402 being disposed within the receiving space, a portion of the rotating screw 401 being disposed within the receiving space, the head end 4011 of the rotating screw 401 extending outside the housing 1, the bushing 402 being connected to the active blade 301, the bushing 402 being sleeved on the outer periphery of the rotating screw 401, the head end 4011 being driven to rotate to drive the bushing 402 to rotate, the bushing 402 driving the active blade 301 to rotate relative to the air outlet 2, and the active blade 301 driving the driven blade 302 to rotate.

[0039] Throughout the process, on-site personnel only need to use tools to drive the head end 4011 so that it can rotate under drive. There is no need to install a power component to adapt to the small capacity of the air outlet 2 and meet the needs of air volume adjustment.

[0040] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the outer peripheral wall of the bushing 402 is provided with a snap-fit ​​groove 4021. The first main body part 3011 of the active blade 301 extends into the snap-fit ​​groove 4021 to snap-fit ​​with it. Through the snap-fit ​​between the snap-fit ​​groove 4021 and the first main body part 3011, the rotation of the bushing 402 drives the rotation of the active blade 301.

[0041] In one embodiment, such as Figure 1 , Figure 3 and Figure 5 As shown, the adjusting assembly 4 also includes a fastener 403 and a washer. The fastener 403 and the bushing 402 are adapted to be respectively disposed on both sides of the first sidewall 5 of the air outlet 2. The fastener 403 and the washer are disposed on the same side. The rotating screw 401 passes through the bushing 402, the first sidewall 5, and the washer in sequence before connecting with the fastener 403. Specifically, the fastener 403 is a nut. By distributing the fastener 403 and the bushing 402 on both sides of the first sidewall 5, the fastener 403 achieves the fastening effect on the rotating screw 401. The washer prevents metal dust generated by metal friction when the fastener 403 and the rotating screw 401 rotate from entering the accommodating space. To strengthen the fastening, there are two fasteners 403 in this embodiment.

[0042] In one embodiment, such as Figure 1 , Figure 2 , Figure 4 and Figure 8 As shown, the active blade 301 also includes a first connecting portion 3012 and a limiting sleeve 3013. The first main body portion 3011 and the first connecting portion 3012 are arranged in an "L" shape. The first connecting portion 3012 passes through the through hole 3032 of the connector 303. The limiting sleeve 3013 is fitted onto the outer peripheral surface of the end of the first connecting portion 3012 that passes through the connector 303. By setting the limiting sleeve 3013, the first connecting portion 3012 is limited after passing through the connector 303 to prevent the first connecting portion 3012 from disengaging from the connector 303, thereby enabling the active blade 301 to drive the connector 303 to move.

[0043] In this embodiment, as Figure 3 and Figure 8 As shown, the active blade 301 has no connection with the first sidewall 5 of the air outlet 2.

[0044] In one embodiment, such as Figure 3 , Figure 4 and Figure 9 As shown, the driven blade 302 also includes a second main body 3021, which has a rotating shaft 3022. The rotating shaft 3022 is rotatably connected to the first sidewall 5 of the air outlet 2. By providing the second main body 3021, the rotating shaft 3022 is rotatably connected to the first sidewall 5, allowing the driven blade 302 to rotate relative to the first sidewall 5 around the rotating shaft 3022 as its axis of rotation. It should be noted that a receiving space is formed between the first sidewall 5 and the second sidewall 6.

[0045] In one embodiment, such as Figure 3 , Figure 4 and Figure 9 As shown, the driven blade 302 also includes a second connecting portion 3023 and a limiting sleeve 3013. The second main body portion 3021 and the second connecting portion 3023 are arranged in an "L" shape. The second connecting portion 3023 passes through the through hole 3032 of the connector 303. The limiting sleeve 3013 is fitted onto the outer peripheral surface of the end of the second connecting portion 3023 that passes through the connector 303. By setting the limiting sleeve 3013, the second connecting portion 3023 is limited after passing through the connector 303, preventing the second connecting portion 3023 from disengaging from the connector 303, thereby enabling the connector 303 to drive the driven blade 302 to rotate relative to the first sidewall 5.

[0046] In this embodiment, as Figure 3 , Figure 5 , Figure 10 and Figure 15As shown, the connector 303 is elongated and has six equally spaced through holes 3032. Each through hole 3032 is suitable for passing through either the first connecting part 3012 or the second connecting part 3023, allowing the connector 303 to connect with one active blade 301 and five driven blades 302, so that the rotation of the active blade 301 drives the rotation of the five driven blades 302. To reduce the overall weight of the connector 303, a hollow portion 3031 is provided between adjacent through holes 3032. Figure 14 As shown, the number of through holes 3032 provided on the connector 303 can also be 13, so that one connector 303 can be connected to one active blade 301 and twelve driven blades 302.

[0047] In one embodiment, such as Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown, the rotating screw 401 also includes an intermediate section 4012 and a threaded end 4013. One end of the intermediate section 4012 is connected to the head end 4011, and the other end of the intermediate section 4012 is connected to the threaded end 4013. The end face of the head end 4011 extending out of the housing 1 is provided with a drive groove 4015. The intermediate section 4012 is provided with an outer plane 4014, and the bushing 402 is provided with an inner plane 4022. The outer plane 4014 and the inner plane 4022 are fitted together. In this embodiment, as... Figure 7 As shown, part of the middle section 4012 is an arc-shaped surface and part is an outer plane 4014, to facilitate the engagement of the rotating screw 401 with the bushing 402, so that the rotating screw 401 drives the bushing 402 to rotate. For easy adjustment, as... Figure 7 As shown, the drive slot 4015 is a slot in the shape of an "I" or a "cross".

[0048] According to an embodiment of the present invention, another aspect is provided: a nozzle comprising at least two sets of the aforementioned corrective blades.

[0049] In one embodiment, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, it also includes a housing 1, along the width direction of the housing 1 ( Figure 1 An air outlet 2 is provided on each side of the housing 1 (in the Y-axis direction). Each air outlet 2 has a receiving space and a correction blade is provided in each air outlet 2. The correction blades are arranged symmetrically. In this embodiment, the correction blades on both sides of the housing 1 are arranged symmetrically, and there are three sets in total. Each set consists of two symmetrically arranged correction blades.

[0050] According to an embodiment of the present invention, another aspect provides an oven including the aforementioned air box.

[0051] A method for using a correction blade: In specific implementation, when the angle of a correction blade needs to be adjusted, on-site personnel use tools to contact the drive groove 4015 of the rotating screw 401. By adjusting the rotation angle of the rotating screw 401, the rotating screw 401 drives the bushing 402 to rotate. The bushing 402 drives the active blade 301 to rotate. The active blade 301 drives the connecting piece 303 to move. The connecting piece 303 then drives the driven blade 302 to rotate, ultimately achieving the common angular movement of the active blade 301 and the driven blade 302.

[0052] It should be noted that the angle of the corrective blades varies depending on the operating conditions. The following three operating conditions serve as examples:

[0053] (1) In the following Figure 11 In the middle, the leftmost correction blade is adjusted 35° to the left, the middle correction blade is adjusted vertically at 0°, and the rightmost correction blade is adjusted 35° to the right to suit the working conditions of large correction force and high electrode surface dryness. It should be noted that the rotation angle and rotation direction of the symmetrical correction blades on both sides of the housing 1 under this working condition are the same.

[0054] (2) Below Figure 12 In the case of the air outlet 2 on one side of the housing 1, the correction blades are uniformly adjusted to the left by 20°, and the correction blades on the air outlet 2 on the other side of the housing 1 are uniformly adjusted to the right by 20°. By controlling the cross air outlets on both sides, the air outlet uniformity deviation is small and the curling edge is not easy to occur.

[0055] (3) Below Figure 13 In the middle, the leftmost correction blade is adjusted 10° to the right, the middle correction blade is adjusted 20° to the right, and the rightmost correction blade is adjusted 30° to the right. By controlling the airflow step by step, the airflow correction is made more stable, reducing shaking and edge curling. It is suitable for the working condition where the overall electrode sheet is fixed and one side is misaligned. It should be noted that the rotation angle and rotation direction of the symmetrical correction blades on both sides of the housing 1 are the same under this working condition.

[0056] It should be noted that the above are only examples of three working conditions, and do not mean that the above-mentioned correction blades can only rotate to a certain angle under the above working conditions. The correction blades can rotate to any angle.

[0057] As an alternative implementation, the number of through holes 3032 on the connector 303 can also be 2, 3, 4, 5, 7 or even more.

[0058] As an alternative implementation, the number of fasteners 403 may also be one.

[0059] As an alternative implementation, the number of corrective blades in the nozzle can be 2, 4, 8, 10 or even more.

[0060] As an alternative implementation, the number of driven blades 302 in a single corrective blade can be 1, 2, 3, 4, 6, 7 or even more.

[0061] As an alternative implementation, the number of active blades 301 in a correction blade can be two, three, four or even more.

[0062] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
