For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0057] In addition, in the description of the present invention, unless otherwise specified, “a plurality of” means two or more.

[0058] For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0059] Please refer to Figure 1 and Figure 2 A nozzle 100 of a coating oven according to a preferred embodiment of the present invention includes: a nozzle body 1, a flow equalizer 2 and a nozzle head 3.

[0060] The nozzle body 1 has a first direction Z, and a first cavity 11 is defined inside the nozzle body 1 .

[0061] The nozzle body 1 also has a second direction Y and a third direction X. The first direction Z, second direction Y, and third direction X intersect with each other. In this embodiment, the first direction Z is the height direction of the nozzle body 1, the second direction Y is the width direction of the nozzle body 1, and the third direction X is the length direction of the nozzle body 1. The nozzle body 1 is the main component of the nozzle. The first direction Z is also the height direction of the nozzle 100, the second direction Y is also the width direction of the nozzle 100, and the third direction X is also the length direction of the nozzle 100.

[0062] Please refer to Figure 7The flow equalizer plate 2 is detachably arranged at one end of the nozzle body 1 along the first direction Z. The flow equalizer plate 2 has a flow equalizer hole 21 connecting the first cavity 11 and the outside of the nozzle body 1.

[0063] For the uniform flow holes 21, the size of the hole can play a role in adjusting the wind speed. A larger hole diameter can increase the drying speed, and a smaller hole diameter can also improve the uniformity of the air output.

[0064] Once the flow-uniform holes 21 are machined on the flow-uniform plate 2 , the size of the holes cannot be changed. The above-mentioned size of the holes refers to the different sizes of the flow-uniform holes 21 of different types of flow-uniform plates 2 .

[0065] The flow equalizer plate 2 is detachably provided on the air nozzle body 1 , so the wind speed can be adjusted by replacing the flow equalizer plate 2 of different types alone without replacing the air nozzle 100 as a whole.

[0066] Please refer to Figure 6 、 Figure 8 and Figure 9 The nozzle head 3 is detachably arranged at one end of the nozzle body 1 away from the uniform flow plate 2 along the first direction Z. The nozzle head 3 has a second cavity 31 inside, and the first cavity 11 is connected to the second cavity 31. An air outlet 32 ​​is provided on the end of the nozzle head 3 away from the nozzle body 1 along the first direction Z, and the second cavity 31 is connected to the outside of the nozzle head 3 through the air outlet 32.

[0067] The wind entering the nozzle 100 from the uniform flow hole 21 first passes through the first cavity 11 and then enters the nozzle head 3. After entering the nozzle head 3, it is blown out from the air outlet 32 ​​to dry the foil.

[0068] Different models of nozzle heads 3 have different air outlet angles. The nozzle head 3 is detachably arranged on the nozzle body 1, so the air outlet angle can be adjusted by replacing different models of nozzle heads 3 separately without replacing the entire nozzle 100.

[0069] The nozzle 100 of the coating oven provided in this embodiment can be replaced with a different model of the current uniform flow plate 2 when the wind speed needs to be adjusted; and the current nozzle head 3 can be replaced with a different model of the nozzle head 3 when the air outlet angle needs to be adjusted. This structure allows the air outlet angle and wind speed of the nozzle 100 to be adjusted without having to replace the entire nozzle 100, thereby improving compatibility.

[0070] Please refer to Figure 3 and Figure 4The air nozzle body 1 includes an air inlet 12 and an air outlet 13. The flow equalizer 2 is detachably arranged at one end of the air inlet 12 along the first direction Z. The air outlet 13 is arranged at the end of the air inlet 12 away from the flow equalizer 2 along the first direction Z. The air nozzle head 3 is detachably arranged at the end of the air outlet 13 away from the guide plate along the first direction Z. The interior of the air inlet 12 and the interior of the air outlet 13 jointly form a first cavity 11. Figure 4 In FIG, the air inlet portion 12 and the air outlet portion 13 are separated by a dotted line.

[0071] Please refer to Figure 5 and Figure 6 The air nozzle 100 of the coating oven also includes a first hanging ring 4 and a first hook 5.

[0072] The first hanging ring 4 is arranged on the outer surface of the nozzle body 1 .

[0073] The first hook 5 is provided on the outer surface of the nozzle head 3 . The position of the first hook 5 corresponds to the position of the first hanging ring 4 . The first hook 5 is used for hooking and connecting with the first hanging ring 4 .

[0074] The hook connection between the first hanging ring 4 and the first hook 5 realizes a detachable connection between the nozzle head 3 and the nozzle body 1 .

[0075] When the first hanging ring 4 is hooked and connected with the first hook 5 , the nozzle head 3 abuts against the nozzle body 1 , and the first cavity 11 is communicated with the second cavity 31 .

[0076] The nozzle head 3 rests on the nozzle body 1 , and the first cavity 11 is directly connected to the second cavity 31 and is not connected to the outside of the nozzle 100 , so that the wind in the first cavity 11 can smoothly enter the second cavity 31 to prevent affecting the air outlet of the nozzle 100 .

[0077] The first hanging rings 4 are provided in two groups. One group of first hanging rings 4 is provided on each of the two end surfaces of the nozzle body 1 arranged along the second direction Y. Each group of first hanging rings 4 is provided in plurality and arranged in sequence along the third direction X. The first hooks 5 correspond one to one with the first hanging rings 4.

[0078] When the first hanging ring 4 and the first hook 5 are hooked with each other, the nozzle head 3 is against the nozzle body 1. The first hanging ring 4 and the first hook 5 are arranged on both end surfaces of the nozzle body 1, which can prevent the nozzle head 3 from deviating on the nozzle body 1.

[0079] The nozzle head 3 and the nozzle body 1 are both longer in the third direction X, so a plurality of first hanging rings 4 and first hooks 5 are provided to ensure a stable connection between the nozzle head 3 and the nozzle body 1 .

[0080] When replacing the nozzle head 3, it is only necessary to release the hooking state between the first hanging ring 4 and the first hook 5 and remove the current nozzle head 3 from the nozzle body 1. When replacing another type of nozzle head 3, the first hook 5 can be hooked and connected to the first hanging ring 4 on the nozzle body 1.

[0081] A first opening 131 is provided at one end of the nozzle body 1 toward the nozzle head 3 along the first direction Z, and the first opening 131 is communicated with the first cavity 11; a second opening 33 is provided at one end of the nozzle head 3 toward the nozzle body 1 along the first direction Z, and the second opening 33 is communicated with the second cavity 31. The first opening 131 and the second opening 33 correspond to each other, and the edge of the first opening 131 and the edge of the second opening 33 abut against each other, so that the first opening 131 and the second opening 33 are directly communicated.

[0082] When the nozzle head 3 is connected to the nozzle body 1, the first opening 131 and the second opening 33 are aligned with each other and are not staggered, so that no part of the first opening 131 or the second opening 33 is exposed outside the nozzle 100. The air in the first cavity 11 can only enter the nozzle head 3, thereby ensuring smooth air discharge from the nozzle 100.

[0083] The first opening 131 may be a strip-shaped opening or a plurality of openings arranged in an array. The shape of the first opening 131 may be set according to the needs in implementation, and the second opening 33 may be set in the same manner.

[0084] The nozzle body 1 has a slot 121 . The slot 121 is provided on one end of the nozzle body 1 away from the nozzle head 3 along the first direction Z. The flow equalizer 2 is inserted into the slot 121 .

[0085] The provision of the slot 121 can achieve a detachable connection between the nozzle body 1 and the flow equalizer plate 2 without affecting the air intake of the flow equalizer holes 21 on the flow equalizer plate 2 .

[0086] The slots 121 cooperate with two opposite sides of the flow equalizer plate 2 to support the flow equalizer plate 2 on the nozzle body 1 .

[0087] The nozzle body 1 includes a body 122 and a limiting plate 123. The body 122 is a hollow structure and forms a first cavity 11. The limiting plate 123 is arranged in the hollow structure inside the body 122. The end face of the body 122 facing away from the nozzle head 3 along the first direction Z is arranged parallel to the limiting plate 123, and a slot 121 is formed between the two. The end face of the body 122 facing away from the nozzle head 3 along the first direction Z has a vacancy 124, and the vacancy 124 reveals the uniform flow hole 21.

[0088] In this embodiment, the limiting plate 123 is arranged inside the nozzle body 1. Under different actual needs, the limiting plate 123 can also be arranged outside the nozzle body 1, as long as the slot 121 is formed so that the flow plate 2 can be detachably connected to the nozzle body 1.

[0089] The provision of the empty space 124 enables the flow-uniform hole 21 to communicate with the first cavity 11 , thereby ensuring that wind can enter the interior of the nozzle body 1 through the flow-uniform hole 21 .

[0090] The nozzle body 1 further includes a side plate 126 . The body 122 has a third opening 125 in the third direction X. The side plate 126 is movably connected to the body 122 to close or open the third opening 125 .

[0091] In this embodiment, the limiting plate 123 is disposed inside the nozzle body 1, that is, the slot 121 is located inside the nozzle body 1. Therefore, when replacing the flow equalizer plate 2, a third opening 125 needs to be provided on the body 122 so that the flow equalizer plate 2 can enter or exit the slot 121 through the third opening 125.

[0092] However, when the tuyere 100 is in operation, the third opening 125 will affect the air inside the tuyere body 1 from entering the tuyere head 3. Therefore, when the tuyere 100 is in operation, the third opening 125 needs to be closed to allow the air inside the tuyere body 1 to smoothly enter the tuyere head 3. The side plate 126 is provided for this purpose.

[0093] When it is necessary to replace the flow plate 2 with another model, the side plate 126 is opened to expose the third opening 125 so that the flow plate 2 can pass through the third opening 125 .

[0094] The air nozzle 100 of the coating oven further includes a second hanging ring 6 and a second hook 7 .

[0095] The second hanging ring 6 is arranged on the end surface of the body 122 along the second direction Y.

[0096] The second hook 7 is provided on the side plate 126 , the side plate 126 is hinged on the body 122 , and the position of the second hook 7 is corresponding to the position of the second hanging ring 6 , and the second hook 7 is used to hook the second hanging ring 6 .

[0097] When the second hanging ring 6 is hooked and connected with the second hook 7 , the side plate 126 abuts against the main body 122 and the third opening 125 is closed.

[0098] The hook connection of the second hanging ring 6 and the second hook 7 realizes the connection between the side plate 126 and the nozzle body 1. When the hook connection of the second hanging ring 6 and the second hook 7 is released, the side plate 126 can release the blockage of the third opening 125, so that the third opening 125 is exposed.

[0099] When the second hanging ring 6 is hooked with the second hook 7, the side plate 126 rests against the main body 122. This arrangement can more tightly seal the third opening 125, preventing excessive leakage of air in the nozzle body 1 from the gap between the third opening 125 and the side plate 126, thereby affecting the normal air outlet of the nozzle 100.

[0100] The two end faces of the main body 122 arranged along the second direction Y are respectively the first end face 14 and the second end face 15 , the side panel 126 is hinged on the first end face 14 , and the side panel 126 can be flipped around the first direction Z; the second hanging ring 6 is set on the second end face 15 .

[0101] The side panel 126 is hinged to the nozzle body 1 . The side panel 126 is flipped on the nozzle body 1 along the first direction Z as the rotation axis. After the side panel 126 is flipped, the third opening 125 is exposed.

[0102] In other embodiments, the side panel 126 may be arranged to flip on the nozzle body 1 along the second direction Y as the rotation axis. In this case, the second hanging ring 6 may be arranged on the first end face 14, the second end face 15, or both.

[0103] This embodiment also provides a coating oven, please refer to Figure 10 , including an upper hull 8, a lower hull 9, a bracket and the above-mentioned wind nozzle 100.

[0104] The lower hull 9 is disposed on one side of the upper hull 8 along the first direction Z, and the lower hull 9 is spaced apart from the upper hull 8 .

[0105] There are multiple tuyere 100 provided between the upper hull 8 and the lower hull 9 .

[0106] The tuyere 100 is connected to the upper hull 8 or the lower hull 9 via a bracket.

[0107] The air nozzles 100 of the upper hull 8 and the lower hull 9 blow air, so that the foil can be suspended between the upper hull 8 and the lower hull 9 , and at the same time, the air nozzles 100 of the upper hull 8 and the lower hull 9 dry the foil.

[0108] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
