Description

Technical Field

[0001] This utility model relates to the technical field of lithium battery coating and drying production equipment, specifically to an adjustable air nozzle and an oven. Background Technology

[0002] In the lithium battery electrode manufacturing process, the coating oven uses a nozzle slit to blow hot air, which impacts the air film on the surface of the wet coating, completing the air convection of the wet coating and the heat conduction between the hot air and the coating. This causes the solvent in the coating to evaporate, and the negative pressure exhaust of the oven carries away the steam, thus completing the drying of the electrode. However, in the nozzle manufacturing process, in order to ensure the consistency of the slit precision, a limiting block is generally used to place in the corresponding air blowing slit area where the coating needs to be dried. This can easily cause the air field to be unstable, and the electrode will shake, resulting in asynchronous drying efficiency and uneven drying. Utility Model Content

[0003] In view of this, the present invention provides an adjustable air nozzle and an oven, which solves the technical problem that the existing air nozzle uses a limiting block placed in the slit area to adjust the slit precision consistency, which easily causes the air field to be unstable, the electrode to shake, and thus the electrode drying efficiency to be asynchronous, resulting in uneven drying and wetting.

[0004] Firstly, this utility model provides an adjustable air outlet nozzle, comprising:

[0005] The first cavity has a first air outlet at the top that communicates with its inner cavity along its length.

[0006] The second cavity is disposed within the first cavity and located at the first air outlet; air outlet slits are formed on both sides of the second cavity and on the inner walls of both sides of the first cavity, and the air outlet slits are connected to the first air outlet;

[0007] Multiple adjustment components are arranged in a rectangular pattern along the length of the first cavity within the first cavity and located below the second cavity. Each adjustment component includes a fixed base and two adjustment members. The fixed base is connected to the bottom of the second cavity. The two adjustment members are staggered along the length of the first cavity on the fixed base, and the adjustment ends of the two adjustment members are respectively connected to the two side plates of the first cavity for adjusting the gap of the air outlet slit.

[0008] Optionally, the adjusting component is an adjusting screw; one end of the adjusting screw is connected to the fixed base, and the other end is slidably inserted through the side plate along the width direction of the first cavity; an outer nut and an inner nut are threadedly connected to the adjusting screw, and the outer nut and the inner nut are respectively located on both sides of the side plate.

[0009] Optionally, spring washers are provided on the adjusting screw between the side plate and the inner nut, and between the side plate and the outer nut.

[0010] Optionally, the fixing base includes a horizontal plate and a vertical plate, the horizontal plate being connected to the bottom of the second cavity, the vertical plate being disposed on the horizontal plate, and the adjusting screw being connected to the vertical plate.

[0011] Optionally, the vertical plate is provided with mounting holes for each of the adjusting screws, the adjusting screws are adapted to pass through the mounting holes, and a fixing nut is threaded onto the adjusting screw, the fixing nut and the head of the adjusting screw are engaged and clamped on the vertical plate.

[0012] Optionally, the top of the second cavity is provided with an air intake that communicates with its inner cavity, and the side of the second cavity is provided with a second air outlet that communicates with its inner cavity.

[0013] Secondly, this utility model provides an oven, including an adjustable air nozzle as described in any of the first aspects.

[0014] The technical solution of this utility model has the following advantages:

[0015] 1. This utility model sets up multiple sets of adjustment components, and uses the adjustment components to adjust the distance between the side plate and the second cavity, thereby adjusting the gap of the air outlet slit. It can adjust the deformation of the side plate caused by processing deformation or other reasons, improve the adjustment accuracy, ensure the accuracy and consistency of the air outlet slit width, and improve production efficiency.

[0016] 2. This utility model reduces the disturbance to the air velocity by placing the adjustment component below the second cavity, away from the air outlet slit, thereby improving the stability of the air field at the air outlet slit and ensuring uniformity during drying.

[0017] 3. The two adjusting components of this utility model are staggered to avoid affecting the adjustment effect and to prevent the two adjusting components from blocking the wind at the same air outlet position. This prevents the two adjusting components from reducing the drying wind speed at the same position of the first air outlet in the direction of substrate running, further improving the stability of the wind field, thereby synchronizing the drying efficiency of the electrode sheet, improving the drying effect, simplifying the overall structure, making the overall weight lighter, and reducing manufacturing costs.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] The following is combined with Figures 1 to 3 The following describes embodiments of the present invention.

[0029] According to an embodiment of the present invention, an adjustable air outlet nozzle is provided, comprising: a first cavity 1, with a first air outlet 2 communicating with its inner cavity along its length at the top; a second cavity 3, disposed within the first cavity 1 and located at the first air outlet 2; air outlet slits 4 formed on both sides of the second cavity 3 and the inner walls of both sides of the first cavity 1, the air outlet slits 4 communicating with the first air outlet 2; and a plurality of adjustment components, arranged at rectangular intervals along the length of the first cavity 1 within the first cavity 1 and located below the second cavity 3; each adjustment component includes a fixed base 5 and two adjustment members, the fixed base 5 being connected to the bottom of the second cavity 3; the two adjustment members being staggered along the length of the first cavity 1 on the fixed base 5, and the adjustment ends of the two adjustment members being respectively connected to the side plates 6 on both sides of the first cavity 1 for adjusting the gap of the air outlet slits 4.

[0030] It should be noted that the second cavity 3 is arranged along the length direction of the first cavity 1, and air outlet slits 4 are formed on the two side plates 6 in the width direction of the first cavity 1.

[0031] The go / no-go gauge is a type of measuring instrument. The gap of the air outlet slit 4 can be determined by the go / no-go gauge. If the no-go gauge fails to pass the lower limit of the gap tolerance, the gap is too small; if the go gauge passes the upper limit of the gap tolerance, the gap is too large.

[0032] In this embodiment, a second cavity 3 is provided within the first cavity 1 to form an air outlet slit 4 with the side wall of the first cavity 1. This allows airflow to be blown out through the first air outlet 2 from the air outlet slits 4 on both sides for drying. Simultaneously, multiple sets of adjustment components are provided below the second cavity 3. A go / no-go gauge can be used to check whether the gap of the air outlet slit 4 is within the acceptable range. When the side plate 6 is deformed outwards, either entirely or partially, causing the gap to widen, the adjustment end of the corresponding adjustment component is used to adjust the side plate 6 inwards, thereby reducing the gap until it reaches the acceptable range. When the side plate 6 is deformed inwards, either entirely or partially, causing the gap to narrow, the adjustment end of the corresponding adjustment component is used to adjust the side plate 6 inwards, thereby increasing the gap until it reaches the acceptable range. The adjustment components... The deformation of the side plate 6 caused by processing deformation or other reasons can be adjusted to ensure the accuracy and consistency of the width of the air outlet slit 4, thereby improving production efficiency. Multiple sets of adjustment components are used to improve adjustment accuracy, and these components are located below the second cavity 3, away from the air outlet slit 4, to reduce disturbance to the air outlet velocity and improve the stability of the airflow field from the air outlet slit 4, ensuring uniformity during drying. Furthermore, the two adjustment components are staggered to avoid affecting the adjustment effect and to prevent them from blocking the airflow at the same air outlet position. This prevents the two adjustment components from reducing the drying velocity at the same position of the first air outlet 2 in the substrate running direction, further improving the stability of the airflow field. This allows for synchronized drying efficiency of the electrode sheets, improving the drying effect, simplifying the overall structure, making the overall weight lighter, and reducing manufacturing costs.

[0033] In one embodiment, such as Figure 2 and Figure 3 As shown, the adjusting component is an adjusting screw 7; one end of the adjusting screw 7 is connected to the fixed base 5, and the other end is slidably mounted on the side plate 6 along the width direction of the first cavity 1; an outer nut 8 and an inner nut 9 are threadedly connected to the adjusting screw 7, and the outer nut 8 and the inner nut 9 are located on both sides of the side plate 6 respectively.

[0034] In this embodiment, an adjusting screw 7 is provided, with one end connected to the fixed base 5 and the other end passing through the side plate 6. The inner nut 9 is located on the inner side of the side plate 6, and the outer nut 8 is located on the outer side of the side plate 6. When it is necessary to adjust the gap of the air outlet slit 4 to be larger, firstly, the outer nut 8 is rotated with a wrench to move it away from the side plate 6 by a predetermined distance. Then, the inner nut 9 is rotated to move it outward against the side plate 6 until the gap is within the acceptable range. Then, the outer nut 8 is rotated again to move it closer to the side plate 6 and to move it in conjunction with the inner nut 9. Nut 9 is used to clamp the side plate 6. When the gap of the air outlet slit 4 needs to be adjusted to be smaller, first, the inner nut 9 is rotated with a wrench to move it away from the side plate 6 by a preset distance. Then, the outer nut 8 is rotated to move it inward against the side plate 6 until the gap is within the acceptable range. Then, the inner nut 9 is rotated again to move it closer to the side plate 6 and clamps the side plate 6 with the outer nut 8. This allows for the adjustment of the gap of the air outlet slit 4, ensuring the accuracy and consistency of the width of the air outlet slit 4. The structure is simple and the adjustment method is convenient and quick.

[0035] In one embodiment, spring washers are provided on the adjusting screw 7 between the side plate 6 and the inner nut 9, and between the side plate 6 and the outer nut 8.

[0036] In this embodiment, spring washers are provided between the side plate 6 and the inner nut 9, as well as between the side plate 6 and the outer nut 8, to prevent the outer nut 8 and the inner nut 9 from loosening due to temperature changes and vibrations, thereby improving stability.

[0037] In one embodiment, such as Figure 2 and Figure 3 As shown, the fixed base 5 includes a horizontal plate and a vertical plate. The horizontal plate is connected to the bottom of the second cavity 3, and the vertical plate is set on the horizontal plate. The adjusting screw 7 is connected to the vertical plate.

[0038] In this embodiment, the fixing base 5 includes a horizontal plate and a vertical plate arranged perpendicularly to each other. The horizontal plate is used to connect to the second cavity 3 with screws, which facilitates installation and disassembly. The vertical plate allows the adjusting screw 7 to maintain a preset distance from the second cavity 3, and thus maintain a preset distance from the air outlet slit 4, so as to avoid affecting the air outlet volume of the air outlet slit 4.

[0039] In one embodiment, such as Figure 2 and Figure 3 As shown, each adjusting screw 7 on the vertical plate has a mounting hole. The adjusting screw 7 is fitted into the mounting hole, and a fixing nut 10 is threaded onto the adjusting screw 7. The fixing nut 10 and the head of the adjusting screw 7 are clamped on the vertical plate.

[0040] In this embodiment, during installation, the rod of the adjusting screw 7 can be passed through the mounting hole until its head abuts against the vertical plate. Then, a fixing nut 10 is fitted onto the adjusting screw 7, and the fixing nut 10 is rotated until it abuts against the vertical plate and cooperates with the head of the adjusting screw 7 to clamp it on the vertical plate, which facilitates installation and disassembly.

[0041] In one embodiment, such as Figure 1 As shown, the top of the second cavity 3 is provided with an air inlet 11 communicating with its inner cavity, and the side of the second cavity 3 is provided with a second air outlet communicating with its inner cavity.

[0042] In this embodiment, an air intake 11 is provided at the bottom of the second cavity 3 to recover part of the air volume blown out of the nozzle slit. The recovered air volume then flows out from the second air outlet to the air outlet slit 4 to balance the lateral pressure of the nozzle and ensure the stability of the foil.

[0043] As an alternative implementation method, the adjusting element can be a telescopic rod, a hydraulic rod, or a pneumatic rod, etc., which can realize automatic adjustment. The specific element can be selected according to actual needs.

[0044] Specifically, such as Figure 2 As shown, a buffer cavity is formed on the side of the first cavity 1 away from the second cavity 3. The adjustment component is located in the buffer cavity. The first cavity 1 is provided with an air inlet that communicates with the buffer cavity, so as to facilitate communication with external equipment to provide drying air.

[0045] The specific working principle of the adjustable air outlet nozzle provided in this embodiment is as follows: The orientation of the first air outlet 2 can be set according to actual needs, and can be upward or downward. The gap of the air outlet slit 4 is checked by a go / no-go gauge to see if it is within the acceptable range. When the side plate 6 is deformed outward in whole or in part, causing the gap to increase, the outer nut 8 is rotated by a wrench at the corresponding position to move it away from the side plate 6 by a predetermined distance. Then, the inner nut 9 is rotated to push against the side plate 6 and move it outward until the gap is within the acceptable range. Then, the outer nut 8 is rotated again to move it closer to the side plate 6 and cooperate with the inner nut 9 to clamp the side plate 6. When the side plate 6 is deformed inward in whole or in part, causing the gap to decrease, the inner nut 9 is rotated by a wrench at the corresponding position to move it away from the side plate 6 by a predetermined distance. The distance is set, and then the outer nut 8 is rotated to move inward against the side plate 6 until the gap is within the acceptable range. Then, the inner nut 9 is rotated again to move closer to the side plate 6 and clamp the side plate 6 with the outer nut 8. This allows for adjustment of the gap of the air outlet slit 4, ensuring the consistent accuracy of the width of the air outlet slit 4. The adjustment method is simple and convenient, saving time and effort, and improving production efficiency. Moreover, the adjustment component is located in the buffer chamber, which avoids the instability of the air outlet slit 4, ensures the uniformity of drying, and improves the drying effect. This solves the technical problem that the existing method of using a limit block placed in the slit area to adjust the slit accuracy of the nozzle is prone to causing unstable air field, electrode vibration, and asynchronous drying efficiency of the electrode, resulting in uneven drying and wetting.

[0046] According to an embodiment of the present invention, in another aspect, an oven is provided, including an air nozzle with an adjustable air outlet as described in any embodiment of the first aspect.

[0047] In this embodiment, the oven adopts an adjustable air outlet nozzle according to any embodiment of the first aspect. The specific structure of the adjustable air outlet nozzle is the same as that of the adjustable air outlet nozzle according to any embodiment of the first aspect, so that the oven with the adjustable air outlet nozzle has at least the same technical effect as the aforementioned adjustable air outlet nozzle. The specific principle is the same as that of any embodiment of the first aspect, and will not be described in detail here.

[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
