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 based on the specific circumstances.

[0027] like Figures 1 to 3 As shown, an embodiment of the present invention provides a nozzle assembly, including a housing 1 and an adjustment mechanism 4. The housing 1 is provided with an air chamber 2, and the housing 1 is provided with an air inlet 3 and an air outlet 6. The air inlet 3 is adapted to be connected to the air source of the drying device, and the air outlet 6 is exposed outside the housing 1 and communicates with the air chamber 2. The air outlet 6 is used to blow air onto the material on the conveying mechanism of the drying device.

[0028] The regulating mechanism 4 is used to adjust the gas flow area of ​​the air outlet 6.

[0029] In this embodiment, as Figure 1 As shown, the first direction is parallel to the X-axis, and the second direction is parallel to the Y-axis. The first direction can be a front-back direction, and the second direction can be a left-right direction.

[0030] The first end of the conveying mechanism of the drying device is connected to the conveying mechanism of the coating device of the coating machine. After the coating device coats the material, the conveying mechanism transports the material to the conveying mechanism. The conveying mechanism transports the material to the drying chamber through the feed port. The air nozzle 6 of the air nozzle assembly blows air onto the material on the conveying mechanism to dry the material.

[0031] In this embodiment, the adjusting mechanism 4 can adjust the gas flow area of ​​the air outlet 6, which means that the adjusting mechanism 4 can adjust the gas flow rate of the air outlet 6, and also means that the adjusting mechanism 4 can adjust the opening size of the air outlet 6, thereby adjusting the blowing area of ​​the air outlet 6, so as to blow air onto the coating area of ​​the material.

[0032] In this embodiment, the adjustment mechanism 4 can adjust the direction of the air outlet 6 toward the material according to the coating area of ​​the material. This can be applied to materials with local coatings, thus increasing the applicability, and can also concentrate the airflow on the coating area of ​​the material, thus improving the drying efficiency.

[0033] In this embodiment, the conveying mechanism is a conveyor belt; in other embodiments, the conveying mechanism may also be a chain mechanism.

[0034] In one embodiment, the air outlet 6 is elongated and extends along a first direction, which is perpendicular to the material conveying direction.

[0035] In this embodiment, the first direction is perpendicular to the material conveying direction, and the air outlet 6 extends along the first direction. The air outlet 6 is horizontally arranged above the conveying mechanism, so that the air outlet 6 can blow air onto all the materials on the conveying mechanism to avoid any material being missed.

[0036] In one embodiment, in the second direction, the width of the air outlet 6 gradually decreases from top to bottom.

[0037] The second direction is perpendicular to the first direction, and the second direction is the material conveying direction.

[0038] In this embodiment, the second direction is the material conveying direction, which is perpendicular to the first direction. The width of the air outlet 6 gradually decreases from top to bottom, which can increase the gas pressure when the gas passes through the air outlet 6, thereby increasing the gas flow rate and further improving the drying effect.

[0039] In one embodiment, the adjustment mechanism 4 includes an adjustment rod 5, which passes through the air outlet 6 along a first direction. The outer peripheral surface of the adjustment rod 5 contacts the inner wall surface of the air outlet 6. The adjustment rod 5 can move in the air outlet 6 along the first direction to adjust the length of the air outlet 6 blocked by the adjustment rod 5.

[0040] In this embodiment, the adjusting rod 5 is inserted into the air outlet 6 along the first direction, and the outer peripheral surface of the adjusting rod 5 contacts the inner wall surface of the air outlet 6 to prevent gas from passing through the gap between the adjusting rod 5 and the air outlet 6. When the adjusting rod 5 moves in the air outlet 6, the air outlet 6 is blocked at the position where the adjusting rod 5 is located, and gas cannot pass through at that part of the air outlet 6. At the unblocked position of the adjusting rod 5, gas can enter the drying chamber through the air outlet 6.

[0041] In this embodiment, the adjusting rod 5 is circular. In other embodiments, the adjusting rod 5 can be rectangular. The outer peripheral surface of the adjusting rod 5 is in contact with the inner wall surface of the air outlet 6.

[0042] In one embodiment, there are multiple adjusting rods 5, which are arranged at intervals along a first direction.

[0043] In this embodiment, "multiple" refers to two or more.

[0044] In this embodiment, there are two adjusting rods 5, which are respectively set at both ends of the air outlet 6 along the first direction. By adjusting the length of the adjusting rods 5 extending into the air outlet 6, the size of the air blowing area in the middle part of the air outlet 6 can be adjusted.

[0045] In this embodiment, the end of the adjusting rod 5 away from the housing 1 can extend outside the housing of the drying device. The length of the adjusting rod 5 extending into the air outlet 6 can be adjusted by manually pushing and pulling the adjusting rod 5. Alternatively, the adjusting rod 5 can be driven to move within the air outlet 6 by a drive mechanism located inside the drying chamber. The drive mechanism can be an electric push rod or a linear motor.

[0046] In one embodiment, the housing 1 is further provided with an air duct 7, which includes a first part 8 and a second part 9, the second part 9 being connected to the first part 8 and the air outlet 6.

[0047] Along the second direction, the width of the first part 8 gradually decreases from top to bottom.

[0048] In this embodiment, the upper end of the first part 8 of the air duct 7 is connected to the air cavity 2, and the second part 9 is connected to the first part 8 and the air outlet 6. The width of the first part 8 gradually decreases from top to bottom, which can increase the pressure of the gas entering the second part 9 through the first part 8, increase the gas flow rate, increase the flow rate of the air blown out of the air outlet 6, and further improve the drying efficiency.

[0049] In this embodiment, an air outlet 6 is provided, and the length of the air outlet 6 is the same as the length of the housing 1 along the first direction.

[0050] In this embodiment, there are two air outlets 6, which are spaced apart along the second direction, and each air outlet 6 is provided with an adjusting rod 5.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] According to the nozzle assembly provided in this embodiment of the present invention, the adjusting mechanism 4 can adjust the gas flow area of ​​the air outlet 6, thereby adjusting the air outlet 6 toward the material's blowing area according to the material's coating area. This can be applied to materials with local coatings, thus improving the applicability range, and can also concentrate airflow on the material's coating area, thus improving drying efficiency.

[0053] In addition, one embodiment of the present invention also provides a drying device, including a housing, a conveying mechanism, an air source and the above-mentioned nozzle assembly. The housing is provided with a drying chamber, the air source is connected to the air inlet 3, and the air source blows air into the air chamber 2 through the air inlet 3. The housing is provided with a feed inlet and a discharge outlet that communicate with the drying chamber. The first end of the conveying mechanism enters the drying chamber from the feed inlet, and the second end of the conveying mechanism enters the drying chamber from the feed inlet and exits the drying chamber from the discharge outlet. The air outlet 6 is directly opposite the conveying mechanism.

[0054] In addition, one embodiment of the present invention provides a coating machine, including a coating device and the aforementioned drying device, wherein the coating device and the drying device are arranged alternately, and the coating device includes a conveying mechanism, with a first end connected to the conveying mechanism.

[0055] In other embodiments, the adjusting rod 5 is fully inserted into the air outlet 6, and neither end of the adjusting rod 5 protrudes from the housing 1. A drive rod can be provided, the diameter of which is much smaller than the diameter of the adjusting rod 5. The drive rod extends out of the housing 1, and the position of the adjusting rod 5 in the air outlet 6 can be adjusted by pushing and pulling the drive rod.

[0056] In other embodiments, multiple air outlets 6 are provided, and the multiple air outlets 6 are arranged at intervals along a first direction, which is perpendicular to the material conveying direction.
