Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating machine technology, and in particular to a drying oven nozzle structure. Background Technology
[0002] The drying oven of a coating machine is used to dry electrode sheets coated with slurry. This drying process is typically achieved by outputting hot air through nozzles. Existing nozzles are generally double-sided airflow structures, although single-sided slit nozzles also exist. However, the airflow angle of typical slit nozzles is not adjustable. Different electrode sheets require specific airflow angles for drying, and the current technology's inability to adjust the nozzle airflow angle results in poor adaptability for drying different electrode sheets. Summary of the Invention
[0003] (a) Technical issues
[0004] The purpose of this invention is to provide a drying oven nozzle structure that solves the problem that the nozzle angle in the prior art cannot be adjusted according to the type of electrode, resulting in poor adaptability to drying different types of electrodes and affecting the drying effect and efficiency.
[0005] (II) Technical Solution
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An oven nozzle structure includes a rotating cylinder with a rotating head rotatably mounted on it. The inner cavity of the rotating head is a first air duct whose width gradually narrows from the rotating cylinder outwards. The rotating cylinder has a first mounting hole and second mounting holes located on both sides of the first mounting hole. The rotating head has a third mounting hole aligned with the first mounting hole and two arc-shaped holes located on both sides of the third mounting hole. Fasteners pass through the third mounting hole and are locked onto the first mounting hole, and limiting members pass through the arc-shaped holes and are locked onto the second mounting holes. A second air duct is formed inside the rotating cylinder, and a first perforated plate located at the inlet end of the second air duct is installed inside the rotating cylinder. An mounting plate is detachably mounted on the rotating cylinder, and the mounting plate has several air inlets communicating with the second air duct.
[0008] Preferably, the rotating cylinder is provided with a first stepped groove located at the opening of the second air duct, and the mounting plate is provided with a second stepped groove that matches the first stepped groove. Hollow rubber strips are provided in the first stepped groove and the second stepped groove, and the hollow rubber strips are sleeved on the first mesh plate.
[0009] Preferably, the rotating head is provided with bent portions on both sides at the opening of the first air duct, and a round rubber strip is provided between the bent portions on the corresponding sides and the rotating cylinder.
[0010] Preferably, the rotating head includes spaced-apart fixed plates, with side plates fixed to both sides of the two fixed plates respectively. The side plates include a vertical plate and an inclined plate. The upper end of the inclined plate is connected to the vertical plate, and the lower end of the inclined plate is inclined inward. The bent portion is fixed to the upper end of the vertical plate.
[0011] Preferably, a second perforated plate is placed inside the rotating head, and the second perforated plate is positioned at the upper end of the inclined plate.
[0012] Preferably, one end of the rotating cylinder is provided with a conical pin, and the other end of the rotating head is provided with a buckle; one end of the mounting plate is provided with a limiting plate that engages with the conical pin, and the other end of the mounting plate is provided with a latch, which is fastened to the buckle.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] See Figures 1-5 As shown, an embodiment of this utility model proposes an oven nozzle structure for installation in the oven of a coating machine to dry coated electrodes. The nozzle structure increases airflow and provides uniform air distribution. Specifically, it includes a rotating cylinder 1, on which a rotating head 2 is rotatably mounted. The inner cavity of the rotating head 2 is a first air duct 3 whose width gradually narrows from the rotating cylinder 1 outwards. Specifically, the rotating cylinder 1 has a first mounting hole 4 and second mounting holes 5 located on both sides of the first mounting hole 4. The rotating head 2 has a third mounting hole 6 aligned with the first mounting hole 4 and two arc-shaped holes 7 located on both sides of the third mounting hole 6. Fasteners pass through the third mounting hole 6 and are locked to the first mounting hole 4, while limiting members pass through the arc-shaped holes 7 and are locked to the second mounting holes 5. Both the fasteners and the limiting members are screws, locked in place through a threaded connection.
[0026] Specifically, fasteners are used to achieve a rotatable connection between the rotating head 2 and the rotating cylinder 1 without separation. The arc-shaped hole 7, in conjunction with the limiting component, allows the rotating head 2 to rotate relative to the rotating cylinder 1 within a certain angle range.
[0027] Based on the requirements of the air inlet angle for the main types of electrode sheets to be dried, the arc-shaped hole 7 restricts the rotation angle range of the rotating head 2 to ±30°, which can be adjusted within a range of 60° according to the air inlet angle requirements, and the adjusted angle is locked by the limiting component.
[0028] Specifically, a second air duct 8 is provided inside the rotating cylinder 1. A first perforated plate 9 located at the inlet end of the second air duct 8 is installed inside the rotating cylinder 1. An installation plate 10 is detachably installed on the rotating cylinder 1. The installation plate 10 is provided with several air inlets 11 that connect to the second air duct 8. The detachable assembly method of the installation plate 10 facilitates the replacement of the internal first perforated plate 9. At the same time, the entire nozzle structure is installed into the drying oven through the installation plate 10. The air passes through the air inlets 11, the first perforated plate 9, and the second air duct 8 in sequence before entering the first air duct 3 and being blown out. The air velocity is increased through the first air duct 3, and the first perforated plate 9 achieves uniform airflow, thereby ensuring that the hot air for drying can evenly contact the electrode sheet for drying and improving the drying effect.
[0029] To seal the mounting plate 10 and the rotating cylinder 1 and prevent air leakage, a first stepped groove 12 is provided on the rotating cylinder 1 at the opening of the second air duct 8, and a second stepped groove 13 matching the first stepped groove 12 is provided on the mounting plate 10. A hollow rubber strip 14 is provided in the first stepped groove 12 and the second stepped groove 13. The hollow rubber strip 14 is sleeved on the first mesh plate 9. The first stepped groove 12 and the second stepped groove 13 form a cavity for placing the hollow rubber strip 14, and it is sleeved on the first mesh plate 9. After the mounting plate 10 and the rotating cylinder 1 are tightly connected, the hollow strip is pressed to seal the connection, thereby ensuring that air flows through the holes on the first mesh plate 9 without leakage.
[0030] Meanwhile, the rotating head 2 is provided with bent portions 15 on both sides of the opening of the first air duct 3. A round rubber strip 16 is provided between the bent portion 15 on the corresponding side and the rotating cylinder 1. During the rotation of the rotating head 2, the round rubber strip 16 keeps the rotation gap sealed to prevent air leakage.
[0031] The rotating head 2 includes spaced-apart fixed plates 21, with side plates fixed to both sides of the two fixed plates 21. The side plates include a vertical plate 22 and an inclined plate 23. The upper end of the inclined plate 23 is connected to the vertical plate 22, and the lower end of the inclined plate 23 is inclined inward. The bent part 15 is fixed to the upper end of the vertical plate 22. The structure of the first air duct 3 is fixed by the fixed plates 21, and it gradually narrows from top to bottom, which can increase the air outlet speed.
[0032] Meanwhile, a second perforated plate 17 is placed inside the rotating head 2. The second perforated plate 17 is positioned at the upper end of the inclined plate 23. The second perforated plate 17 further distributes the airflow evenly, ensuring that the airflow at the air outlet is uniform.
[0033] Specifically, the mounting plate 10 and the rotating cylinder are detachably mounted. A conical pin 18 is provided at one end of the rotating cylinder, and a buckle 19 is provided at the other end of the rotating head 2. A limiting plate 20 is provided at one end of the mounting plate 10 to engage with the conical pin 18, and a latch 21 is provided at the other end of the mounting plate 10. The latch 21 is fastened to the buckle. The limiting plate 20 is inserted into the conical pin 18 to form a limiting connection, and the mounting plate 10 is pressed onto the rotating cylinder by the latch 21 and the buckle.
[0034] To improve corrosion resistance and structural strength, the rotating cylinder 1, the rotating head 2, and the mounting plate 10 are all made of stainless steel.
