Description

Technical Field

[0001] This utility model relates to an air nozzle, and more particularly to an air nozzle for a coating machine oven. Background Technology

[0002] In the electrode coating process of large cylindrical lithium batteries, the airflow speed adjustment of the nozzles in the oven inside the coating machine has certain limitations. Specifically, the airflow speed of the nozzles in the oven can only be adjusted synchronously as a whole, and it is not possible to achieve independent airflow speed control for specific areas or arbitrary parts of the nozzles. This adjustment method lacks flexibility and cannot meet the differentiated airflow speed requirements of different areas. In actual production, due to the differences in electrode material characteristics and coating process requirements, it is often necessary to finely adjust the airflow speed of nozzles at different locations, but existing equipment cannot achieve this local adjustment function, which to some extent affects the uniformity and consistency of coating quality. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a coating machine oven nozzle, thereby realizing local adjustment.

[0004] To achieve the above objectives, this utility model discloses a coating machine drying oven nozzle, comprising: The main body is frame-shaped and has a first opening and a second opening that are relatively parallel to each other on both sides. An air outlet plate, wherein the air outlet plate array is provided with an air outlet, and the air outlet plate is connected to a first opening; A wind deflector, wherein the wind deflector array is provided with an air inlet, and the wind deflector is connected to a second opening; The air outlet plate is fixed relative to the main body, and the wind baffle plate is slidably connected to the main body. The wind baffle plate can be slidable so that the air outlet and the air inlet are offset from each other or overlap.

[0005] Preferably, the wind deflector includes an array of adjacent panels arranged sequentially, and the array of air outlets is distributed on the panels.

[0006] Preferably, studs are provided on the relatively parallel sides of the wind deflector, and the studs pass through one side of the main body and are connected to nuts to fix the wind deflector relative to the main body.

[0007] Preferably, at least one side of the stud is provided with a guide protrusion, the main body is provided with a sliding groove, and the guide protrusion extends into the sliding groove; during the sliding of the partition plate, the guide protrusion slides in the sliding groove.

[0008] Preferably, the main body includes a first plate, a second plate, a third plate, and a fourth plate connected end to end in sequence. The first plate, the second plate, the third plate, and the fourth plate enclose each other to form a rectangular frame. The first plate, the second plate, the third plate, and the fourth plate are connected to each other by fasteners.

[0009] Preferably, the first plate and the third plate are provided with a first hole for the stud to pass through, and the groove is provided on the first plate.

[0010] This utility model has the following technical effects: 1. The position of the baffle can be more precisely controlled by the nut. The maximum wind speed can be achieved when the air outlet and the air inlet are completely aligned, and the minimum wind speed can be achieved when the air outlet and the air inlet are completely offset, thus making it easy to control the flow rate. 2. The wind deflector adopts a multi-segment design, which allows the airflow to be precisely directed to the required area in a preset manner, avoiding ineffective airflow scattering, making energy use more efficient and reducing ineffective energy loss.

[0013] The principles and features of this utility model are described below with reference to the embodiments; the examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0014] Example 1 A coating machine drying oven nozzle includes a main body 100, an air outlet plate 200, and an air baffle plate 300. The main body 100 is a rectangular frame shape, and includes a first plate 104, a second plate 105, a third plate 106, and a fourth plate 107. The first plate 104, the second plate 105, the third plate 106, and the fourth plate 107 are connected end to end in sequence and fixed relative to each other by bolts or screws, according to the attached... Figure 3 As shown in the diagram, the first plate 104 and the third plate 106 are vertically opposite each other, and the second plate 105 and the fourth plate 107 are horizontally opposite each other. A first opening 101 and a second opening 102 are formed on opposite sides of the main body 100. An air outlet plate 200 is connected to the first opening 101, and a baffle plate 300 is connected to the second opening 102. Air outlets 201 are arranged in a rectangular array on the air outlet plate 200, and air inlets 301 are arranged in a rectangular array on the baffle plate 300. Both air outlets 201 and air inlets 301 are through holes. The air outlet plate 200 is fixedly connected to the main body 100, and the baffle plate 300 is slidably connected to the main body 100. The baffle plate 300 is slidable, causing the air outlets 201 and air inlets 301 to be offset from or overlap each other. When the air outlet 201 and the air inlet 301 are offset from each other, the flow velocity is at its minimum; when the air outlet 201 and the air inlet 301 coincide, the flow velocity is at its maximum, thus allowing for flow velocity adjustment according to process requirements. In this embodiment, the baffle plate 300 is a single piece.

[0015] Specifically, a first hole 108 is provided on the first plate 104 and the third plate 106, and the first hole 108 is through-hole. Simultaneously, a sliding groove 103 is also provided on the first plate 104, with the sliding groove 103 positioned on both sides of the first hole 108. (See attached diagram.) Figure 2 Regarding the positional relationship, studs 303 are respectively provided on the upper and lower sides of the wind deflector 300. The studs 303 pass through the first hole 108 and are connected to nuts 305. Tightening the nuts 305 can fix the wind deflector 300 relative to the main body 100; loosening the nuts 305 can allow the wind deflector 300 to slide relative to the main body 100. Guide protrusions 304 are also provided on both sides of the studs 303, and the guide protrusions 304 extend into the sliding grooves 103. During the up and down movement of the wind deflector 300, the guide protrusions 304 slide within the sliding grooves 103.

[0016] Example 2 The difference from Embodiment 1 is that in this embodiment, the wind deflector 300 consists of three separate plates 302 arranged in sequence. Each separate plate 302 can be individually adjusted relative to the main body 100, thereby meeting the product's requirements for different wind speeds.

[0017] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
