Description

Technical Field

[0001] The utility model belongs to the technical field of coating machines, and particularly relates to an adjustable air nozzle and a coating machine. Background Art

[0002] Coating is a process in which a slurry is applied to the surface of a substrate, followed by drying and winding. Conventional technology typically uses a coating machine to apply the slurry to the substrate, which is then fed into one or more drying ovens to dry the slurry. The ovens are typically equipped with multiple nozzles to blow air onto the substrate surface to accelerate drying.

[0003] Coating is an essential process in the production of lithium-ion batteries and a key step that directly impacts battery safety, capacity, and other performance characteristics. It primarily involves coating a prepared slurry onto a substrate. To dry the slurry, the coating machine is typically equipped with a drying device. In related technologies, the coating machine's drying device primarily includes an oven and a nozzle. The oven is equipped with an air duct for introducing hot air, while the duct is equipped with an air outlet. The nozzle is fixedly mounted at the duct outlet to direct the hot air onto the substrate to be dried, thereby drying the slurry on the coating machine.

[0004] The coating machine is the front-end equipment of new energy. The foil used to make battery materials needs to go through the drying process before subsequent work can be carried out. The airflow is discharged from the air nozzle to the top of the electrode. Due to the structure of the electrode hull, the airflow usually flows to both sides after contacting the electrode. This phenomenon will cause the lateral flow rate on both sides of the electrode to be faster than that in the middle, resulting in excessive drying on both sides, resulting in abnormal appearance and quality of the electrode. This phenomenon is particularly obvious when the equipment is wider.

[0005] Chinese patent CN202320373321.0 provides an adjustable air outlet nozzle and drying equipment. An air outlet adjustment component is provided in a guide cavity connected to the air outlet near the air outlet; the air outlet adjustment component includes a movable baffle, a first closing plate and a second closing plate, which can move forward and backward in the length direction of the guide cavity; the first closing plate and the second closing plate are arranged opposite to each other in the width direction of the guide cavity, and can move toward each other or move away from each other. There are the following areas for improvement: solving the problem of poor straightness and easy deformation of the air outlet of the sheet metal nozzle, resulting in poor air outlet uniformity; the need to set up guide rails and screws, resulting in excessive weight, difficulty in installation, and difficulty for workers to carry; the adjustment range is limited by the size of the movable baffle and the two closing plates, that is, between the complete overlap and complete non-overlap of the movable baffle and the closing plate, which is quite limited; the air outlet adjustment component is located in the air guide cavity in front of the air outlet, which easily causes the blocked wind to generate turbulence in the air guide cavity, affecting the air outlet and return air.

[0006] Chinese patent CN202322164066.1 provides a nozzle structure of a coating machine and a coating machine. The nozzle structure of the coating machine includes: a nozzle body, which defines an air guide cavity and an air inlet, a ventilation part and an air outlet connected to the air guide cavity, and the ventilation part and the air outlet are located on the same side of the air guide cavity; a shielding part, which is located in the air guide cavity, and the shielding part is constructed to be able to block part of the ventilation part. Along the length direction of the nozzle body, the two ends of the nozzle body are provided with shielding parts, and each shielding part can be unfolded or folded along the length direction of the nozzle body to adjust the air outlet of the ventilation part. It has the following aspects to be improved: its adjustable air outlet part is not a part that is usually used directly for air outlet, but is located in the ventilation part for ventilation and return air.

[0007] Therefore, how to better adjust the air outlet length of the air outlet nozzle of the coating machine is a technical problem that needs to be solved urgently in this field. Utility Model Content

[0008] In view of the existing phenomenon, the present invention provides a method to solve at least one of the above technical problems.

[0009] The technical solution provided in this application is an adjustable air nozzle, including an air nozzle body, the air nozzle body having an air outlet and an air outlet adjustment component; the air outlet adjustment component includes a reel arranged at both ends of the air outlet and a flexible baffle wound on the reel; when the reel rotates, the end of the flexible baffle moves back and forth in the length direction of the air outlet.

[0010] Furthermore, it includes a synchronization member that causes the reels at both ends to rotate simultaneously in opposite directions. The synchronization member includes two synchronization wheels that are respectively connected to the two rotating shafts in a transmission manner, and a synchronization rope wound around the two synchronization wheels.

[0011] Furthermore, it includes an elastic member that connects and tensions the ends of two flexible baffles in the air outlet.

[0012] Furthermore, it includes a hand wheel connected to the reel transmission.

[0013] Furthermore, the air nozzle body includes an air return port for returning air, and two air outlets located on both sides of the air return port, and both air outlets are provided with an air outlet adjustment component.

[0014] Furthermore, an indicator line indicating the position of the flexible baffle is provided on the edge of the air outlet.

[0015] Furthermore, the air nozzle body includes a main beam constituting a side surface of the air outlet, and the main beam includes a limiting portion covering a side surface of the flexible baffle.

[0016] Furthermore, it also includes side panels connected to the main beam, and the side panels are provided with waist-shaped holes for adjusting the height.

[0017] Furthermore, the flexible baffle is made of Teflon.

[0018] Another technical solution provided by the present application is a coating machine, comprising the above-mentioned adjustable air nozzle.

[0019] The beneficial effects of this application are at least:

[0020] An adjustable air nozzle and a coating machine are provided. The adjustable air nozzle of the present application uses a flexible baffle to block both ends of the air outlet, which can make the airflow blown out through the air outlet more concentrated toward the center of the wind-receiving object, such as the pole piece. Compared with the solutions in the prior art that use rigid parts such as baffles, sheet metal parts, etc. to adjust the air outlet, the flexible baffle of the present application is not prone to irreversible deformation, has good air outlet straightness, and can be provided on a reel, which makes it easy to set up a lighter drive mechanism and facilitate transportation and installation. Since the flexible baffle of the present application is wound on a reel, it can be completely reeled or unfolded, so that the adjustable range of blocking the air outlet is much greater than that of a rigid shielding member.

DETAILED DESCRIPTION

[0031] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0032] In the description of this application, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0033] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0034] In the description of this embodiment, the terms "upper," "lower," "left," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meanings.

[0035] Please refer to Figure 1-7Embodiment 1 provides an adjustable air nozzle, including an air nozzle body, the air nozzle body having an air outlet 1 and an air outlet adjustment component 2; the air outlet adjustment component 2 includes a reel 21 provided at both ends of the air outlet 1 and a flexible baffle 22 wound on the reel 21; when the reel 21 rotates, the end of the flexible baffle 22 moves back and forth in the length direction of the air outlet 1.

[0036] The adjustable air nozzle of the present application uses a flexible baffle 22 to block both ends of the air outlet 2, which can make the airflow blown out through the air outlet 2 more concentrated toward the center of the wind-receiving object, such as the pole piece. Compared with the solutions in the prior art that use rigid parts such as baffles and sheet metal parts to adjust the air outlet, the flexible baffle 22 of the present application is not prone to irreversible deformation, has better air outlet straightness, and can be set on the reel 21, which makes it easy to set a lighter drive mechanism and facilitate transportation and installation. Because the flexible baffle 22 of the present application is wound on the reel 21, it can be completely retracted or unfolded, so that the adjustable range of blocking the air outlet 2 is much greater than that of a rigid shielding member.

[0037] Please refer to Figure 2-3 In this embodiment, a synchronizer 3 is included that causes the reels 21 at both ends to rotate simultaneously in opposite directions. The synchronizer 3 includes two synchronizer wheels 31 that are respectively connected to the two rotating shafts, and a synchronizer rope 32 wound around the two synchronizer wheels 31. Driving one reel 21 to rotate can cause the two reels 21 to rotate simultaneously in opposite directions, driving the flexible baffles 22 to move synchronously and symmetrically. Using the synchronizer 3 to synchronize the reels 21 at both ends can simplify the transmission, allowing the flexible baffles 22 at both ends of the air outlet 2 to move synchronously toward or away from each other, avoiding the duplication of drive components and simplifying the control difficulty. Specifically, the synchronizer wheel 31 of the present application is a steel rope roller that rotates synchronously with the reel 21, and the synchronizer rope 32 is a steel rope wound around the synchronizer wheel 31.

[0038] Please refer to Figure 4 In this embodiment, an elastic member 4 is provided that connects and tensions the ends of two flexible baffles 22 in the air outlet 1. Tensioning the flexible baffles 22 causes them to move closer together and straighten, automatically forming a guide, further improving the straightness of the airflow after the linear shielding. This is a lightweight and simple-to-implement guide mechanism. Specifically, the elastic member 4 is a spring that hooks into a hole at the end of the flexible baffle 22.

[0039] In this embodiment, a hand wheel 5 is included which is in transmission connection with the reel 21, so that an operator can hold and rotate it for adjustment.

[0040] In this embodiment, the air nozzle body includes a return air port 6 for returning air, and two air outlets 1 are located on both sides of the return air port 6. Both air outlets 1 are provided with an air outlet adjustment assembly 2. The return air port 6 is a prior art, which is used to allow the vortex formed by the wind flow on the wind-receiving object to enter, so as to improve the uniformity of the wind blown by the air nozzle onto the surface of the wind-receiving object. The symmetrical arrangement of the air outlet 6 and the air outlet adjustment assembly 2 is also to improve the uniformity and synchronize the air outlet on both sides of the return air port 6. In this embodiment, the two scrolls 21 of the two groups of air outlet adjustment assemblies 2 near the same end of the air outlet are respectively provided on the same rotating shaft, and one end of the rotating shaft is fixedly connected to a hand wheel 5, so the two groups of air outlet adjustment assemblies 2 can synchronously adjust the degree of shielding, and the position of all flexible baffles 22 can be adjusted by using a hand wheel 5 in conjunction with the synchronization member 3, thereby simplifying the transmission and facilitating the operation.

[0041] Please refer to Figure 5 In this embodiment, an indicator line 7 indicating the position of the flexible baffle 22 is provided on the edge of the air outlet 1. The operator can adjust the position of the flexible baffle 22 and determine whether the positions of the flexible baffles 22 at both ends of the same air outlet 1 are symmetrical and synchronized according to the indication of the indicator line 7.

[0042] Please refer to Figure 6 In this embodiment, the nozzle body includes a main beam 8 that forms the side of the air outlet 1. The main beam 8 includes a limiting portion 81 that covers the side of the flexible baffle 22. That is, it limits the flexible baffle 22 on the outside of the flexible baffle 22, further improving the positional stability of the flexible baffle 22 and the straightness of the air outlet. It should be noted that the other structures of the nozzle body in this embodiment are similar to those of nozzles in the prior art, including an air inlet 100 for intake, several connectors for connecting to the coating machine, and several sealing plates and sealing strips that constitute the nozzle body and form the air inlet 100, the air outlet 2, and the sealed air guide cavity.

[0043] Please refer to Figure 7 In this embodiment, the adjustable nozzle further includes side panels 9 connected to the main beam 8. These side panels are provided with waist-shaped holes 91 for adjusting the relative distance from the windward object. Specifically, the height refers to the relative distance between the adjustable nozzle and the windward object. This height can be adjusted by adjusting the mounting position of the connector within the waist-shaped hole 91. Optionally, a second indicator line indicating the mounting position may be provided on the outside of the waist-shaped hole 91.

[0044] In this embodiment, the flexible baffle 22 is made of Teflon. The Teflon flexible baffle is resistant to high temperature, corrosion, and has good softness. It is suitable as the flexible baffle 22 of this application and is conducive to maintaining good air outlet straightness.

[0045] Example 2 provides a coating machine, including the adjustable air nozzle of Example 1, having all its technical features and beneficial effects.
