Description

Technical Field

[0001] This invention relates to high-temperature gas heating or drying equipment, and more particularly to a nozzle box and an air outlet device. Background Technology

[0002] The airflow blown by the high-temperature gas blowing equipment can heat and dry the workpiece. Usually, the hot airflow is divided into multiple branch pipes by the main air duct. The end of the branch pipe is equipped with a nozzle, and the hot airflow is blown out through different nozzles. When the processing requirements of the workpiece change, the position of the nozzle needs to be adjusted at the same time. In related technologies, a flexible connection structure, such as a metal corrugated pipe or a silicone hose, is set between the branch pipe and the nozzle to realize a soft connection between the branch pipe and the nozzle, so that the nozzle can change position.

[0003] Metal corrugated pipes are only suitable for making round air outlets and cannot be matched with rectangular, slender or other shaped nozzles. Silicone materials have low strength and short lifespan, requiring frequent replacement and are not very convenient to use. Summary of the Invention

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0054] Reference Figures 1 to 4 An embodiment of the present invention provides a nozzle box 100, which includes a base box 110, a nozzle 120, a protective cover 130, and a sealing partition 140. The base box 110 includes two parallel and spaced-apart mounting portions 111, both extending along a first direction. The mounting portions 111 are used for mounting the nozzle 120, the protective cover 130, and the sealing partition 140. Multiple nozzles 120, protective covers 130, and sealing partitions 140 are provided. Both ends of the nozzles 120, protective covers 130, and sealing partitions 140 are respectively connected to the two mounting portions 111. At least the nozzle 120 can change its position along the first direction, and the side portion of the protective cover 130 in the first direction can change its position along the first direction. The nozzle 120 has an air outlet 121 for drawing out airflow from the air outlet channel, thereby continuing to heat and dry the workpiece.

[0055] Multiple sealing partitions 140 are arranged at intervals along a first direction. At least one air nozzle 120 is provided between adjacent sealing partitions 140, and several protective covers 130 are provided between the air nozzles 120 and the sealing partitions 140. The sealing partitions 140 are used to isolate adjacent air outlet channels. That is, the area defined between adjacent sealing partitions 140 is connected to only one air outlet channel, and the airflow is discharged through the air outlet 121 of the air nozzles 120 located between adjacent sealing partitions 140. This can prevent the airflow discharged in the air outlet channel from moving around or forming turbulence, which would affect the air outlet effect of the air nozzles 120.

[0056] The nozzle 120 and the cover 130 are jointly disposed within the space defined by the adjacent sealing partition 140. Since the positions of the sides of the nozzle 120 and the cover 130 in the first direction are adjustable, when the position of the nozzle 120 needs to be changed, the position of the side of the cover 130 in the first direction can be changed to provide space for the nozzle 120 to change position. Thus, the position of the nozzle 120 in the first direction can be adjusted according to the position requirements of the nozzle 120. The shape of the air outlet 121 of the nozzle 120 is not limited and can meet a variety of air outlet requirements. Furthermore, the cover 130 and the sealing partition 140 do not need to be made of silicone-like flexible materials, have a long service life, do not require frequent maintenance, and the nozzle box 100 is highly convenient to use.

[0057] like Figure 5 As shown, the nozzle 120 includes an air outlet body 122 and an air outlet 121 located at the lower end of the air outlet body 122. The air outlet 121 is a long and narrow rectangular slit, which makes the air outlet range more precise and can be used to heat and dry long strip areas. The air outlet body 122 is tapered from top to bottom, which guides the airflow inside the air outlet body 122 and concentrates the airflow to be discharged from the air outlet 121 for targeted heating and drying.

[0058] The way in which the nozzle 120 changes position along the first direction is not limited to: sliding relative to the mounting portion 111 along the first direction; being detachably mounted to the mounting portion 111 and changing position by disassembly, etc. The way in which the side portion of the cover 130 (hereinafter referring to the side portion of the cover 130 in the first direction) changes position along the first direction is not limited to: sliding relative to the mounting portion 111 along the first direction; being detachably mounted to the mounting portion 111 and changing position by disassembly; being detachably mounted to the mounting portion 111 and replaced with a cover 130 having a different width in the first direction; being detachably mounted to the mounting portion 111 and increasing or decreasing the number of covers 130 between adjacent sealing partitions 140, etc.

[0059] For example, taking the end of the sealing partition 140 as fixed to the mounting part 111 (that is, the sealing partition 140 is fixed relative to the mounting part 111 in the first direction), the position of the nozzle 120 in the first direction is adjusted by changing the position of the side of the cover 130 in the first direction. Specifically, both the nozzle 120 and the cover 130 are detachably connected to the mounting part 111. Provided that the nozzle 120 and the cover 130 are fixed relative to the mounting part 111 after installation and can be moved or separated relative to the mounting part 111 during disassembly, the detachable connection method is not limited to threaded connection, snap-fit, crimping, etc. When it is necessary to change the position of the nozzle 120, the cover 130 is removed, the number of covers 130 is increased or decreased, or covers 130 with different widths are replaced, so that the position of the side of the cover 130 in the first direction changes, thereby changing the size of the space between the cover 130 and the sealing partition 140. Then the nozzle 120 is removed and the position of the nozzle 120 in the first direction is changed. After the position of the nozzle 120 is determined, the nozzle 120 and the cover 130 are relocked.

[0060] Alternatively, in another embodiment, the end of the sealing partition 140 is fixed to the mounting portion 111, the protective cover 130 is detachably connected to the mounting portion 111, and the nozzle 120 is slidably connected to the mounting portion 111 and can slide relative to the mounting portion 111 in the first direction. The nozzle 120 is clamped between the nozzle and the adjacent protective cover 130, that is, the position of the nozzle 120 in the first direction is fixed by the clamping force applied by the protective covers 130 on both sides. When it is necessary to change the position of the nozzle 120, the protective covers 130 on both sides of the nozzle 120 are removed, and the width specification or number of the protective covers 130 is changed to change the position of the side of the protective cover 130. The nozzle 120 is slid so that the nozzle 120 changes its position in the first direction synchronously with the protective cover 130. After the position of the nozzle 120 is determined, the protective covers 130 on both sides of the nozzle 120 are re-fixed so that the nozzle 120 is clamped again.

[0061] When the cover 130 and the nozzle 120 are detachably connected to the mounting part 111, the detachable connection can be as follows: taking the connection between the cover 130 and the mounting part 111 as an example, the mounting part 111 is provided with a groove extending in the first direction, and threaded fasteners pass through the cover 130 and the mounting part 111, locking the cover 130 to the mounting part 111. When the cover 130 needs to be removed, the threaded fasteners can be loosened to remove the cover 130 from the mounting part 111; or, the mounting part 111 is provided with a plurality of buckles arranged at intervals in the first direction, and the end of the cover 130 is engaged with the buckles. When the cover 130 needs to be removed, the engagement between the cover 130 and the buckles can be released to remove the cover 130 from the mounting part 111.

[0062] Of course, the sealing partition 140 can also be changed in position in the first direction simultaneously, making the position adjustment of the nozzle 120 more flexible. For example, the nozzle 120, the cover 130, and the sealing partition 140 are all detachably connected to the mounting part 111. When the position of the nozzle 120 needs to be changed, the cover 130 and the sealing partition 140 are removed to provide space for the nozzle 120 to change position. After the nozzle 120 is moved to the desired position, the cover 130 and the sealing partition 140 are reinstalled, and their positions are fixed. Since the sealing partition 140 is used to isolate adjacent air outlet channels, it needs to be positionally matched with the corresponding structure within the oven 200 to achieve a seal. The movement range of the sealing partition 140 is limited. When the position change of the nozzle 120 exceeds the movement range of the sealing partition 140, the position change requirement of the nozzle 120 can be met by increasing or decreasing the number of covers 130 and changing the width specifications of the covers 130.

[0063] It is understandable that the detachable connection between the sealing partition 140 and the mounting part 111 is not limited to clamping between adjacent protective covers 130; or threaded connection, snap-fit, crimping, etc. with the mounting part 111.

[0064] In addition, there is at least one width of cover 130 between the nozzle 120 and the sealing partition 140. When it is necessary to change the position of a certain nozzle 120, a spare cover 130 can be replaced to the position of the current cover 130, or the cover 130 between other nozzles 120 and the sealing partition 140 can be replaced to the position of the current cover 130.

[0065] In one embodiment, the shield 130 has multiple parts slidably connected in a first direction. The positions of the different parts in the first direction are variable. By adjusting the relative positions of the different parts within the shield 130, the overall width of the shield 130 can be adjusted. When the position of the nozzle 120 needs to be changed, the position of the side of the shield 130 can be changed without removing the shield 130, thereby meeting the requirement to change the position of the nozzle 120 in the first direction. Specifically, at least one of the shields 130 between adjacent sealing partitions 140 includes a shield body 131. A movable part 132 is provided on at least one side of the shield body 131 along the first direction. The movable part 132 is slidably connected to the shield body 131 along the first direction. When the movable part 132 moves away from the shield body 131, the overall width of the shield 130 increases; when the movable part 132 moves towards the shield body 131, the overall width of the shield 130 decreases.

[0066] Thus, when the position change of the nozzle 120 is small, the preferred method is to move the moving part 132 relative to the cover body 131 to change the overall width of the cover 130, thereby adjusting the position of the nozzle 120. For example, the moving part 132 in the cover 130 on the first side of the nozzle 120 can be adjusted to move towards the cover body 131 to reduce the overall width of the cover 130, while the moving part 132 in the cover 130 on the second side of the nozzle 120 (opposite to the first side) can be adjusted to move away from the cover body 131 to increase the overall width of the cover 130, thereby moving the nozzle 120 towards the first side and adjusting the position of the nozzle 120. When the position change of the nozzle 120 is large and exceeds the adjustment range of the overall width of the cover 130, it is possible to supplement by replacing the cover 130 with one of different widths or adding or removing covers 130 to expand the adjustable range of the nozzle 120 position and meet the position adjustment requirements of the nozzle 120.

[0067] Understandably, both sides of the protective cover body 131 are provided with movable parts 132, and both movable parts 132 can slide relative to the protective cover body 131, thereby increasing the overall width adjustment range of the protective cover 130.

[0068] The sliding method of the movable part 132 relative to the protective cover body 131 is not limited to: at least a part of the movable part 132 is inserted into the protective cover body 131 and can move closer to or further away from the protective cover body 131 to realize the movement of the movable part 132 relative to the protective cover body 131; or, the movable part 132 overlaps with the protective cover body 131, and the top of the protective cover body 131 is provided with a guide groove that cooperates with and connects to the movable part 132, so as to restrict the movable part 132 to move relative to the protective cover body 131 in a first direction, and the movable part 132 is slidably connected in the guide groove.

[0069] In one embodiment, at least a portion of the movable part 132 covers the top of the cover body 131, or the cover body 131 covers at least a portion of the top surface of the movable part 132. When the movable part 132 moves relative to the cover body 131, the contact area between the movable part 132 and the cover body 131 increases or decreases. When the contact area increases, the overall width of the cover 130 decreases; when the contact area decreases, the overall width of the cover 130 increases. Taking the example where at least a portion of the movable part 132 covers the top of the cover body 131, the top surface of the cover body 131 has a contour that matches the bottom surface of the movable part 132 to constrain the movement direction of the movable part 132 and achieve a sliding connection between the movable part 132 and the cover body 131.

[0070] Additionally, the movable part 132 is connected to the nozzle 120 or other covers 130 on the side facing away from the cover body 131, so that the connections between multiple covers 130 and between the cover 130 and the nozzle 120 are secure, forming a stable assembly structure. When it is necessary to change or remove the cover 130 or replace the nozzle 120, the operation can be performed from the bottom of the nozzle box 100 to disconnect the connections between adjacent covers 130 and between the cover 130 and the nozzle 120, so that the cover 130 and the nozzle 120 can be moved away from or relative to the mounting part 111.

[0071] In one embodiment, refer to Figure 6 The nozzle 120 also includes a first flange 123 and a second flange 124 arranged vertically at intervals. Both ends of the air outlet body 122 are provided with the first flange 123 and the second flange 124. The first flange 123 is located above the second flange 124. The mounting part 111 is located between the first flange 123 and the second flange 124. The first flange 123 and the second flange 124 define a gap that allows the mounting part 111 and the nozzle 120 to slide together. Both the first flange 123 and the second flange 124 can move relative to the mounting part 111 in a first direction. The first flange 123 is connected to the upper surface of the mounting part 111, and the second flange 124 is connected to the lower surface of the mounting part 111. The nozzle 120 is connected to the mounting part 111 on both the upper and lower sides, which strengthens the connection between the nozzle 120 and the mounting part 111, giving the nozzle 120 high positional stability and high airflow delivery accuracy during airflow blowing.

[0072] Additionally, refer to Figure 1 and Figure 2 The nozzle box 100 also includes a pressing assembly 150, which is used to fix the nozzle 120 and the cover 130 on the mounting part 111 by pressing. Specifically, the pressing assembly 150 includes a plurality of sealing strips 151 and a plurality of pressing members 152. Each sealing strip 151 is provided with a plurality of pressing members 152, and the pressing members 152 are arranged along a first direction. The covers 130 located between adjacent sealing partitions 140 are all pressed by the pressing assembly 150. Therefore, the pressing members 152 located at different positions can press the covers 130 at different positions. Specifically, refer to Figure 8The sealing strip 151 is connected to the first flange 123. Since the position of the nozzle 120 is fixed by the first flange 123 and the second flange 124, connecting the sealing strip 151 to the first flange 123 can further fix the position of the sealing strip 151. The sealing strip 151 covers the part of the cover 130 and the part of the nozzle 120 that overlaps with the upper surface of the mounting part 111. That is, the sealing strip 151 covers the top of the first flange 123 and the part of the cover 130 that contacts the mounting part 111. The top of each cover 130 abuts against at least one crimping member 152. By crimping the cover 130 with the crimping member 152, the cover 130 is stably connected to the mounting part 111.

[0073] Understandably, fixing the cover 130 by crimping allows for convenient changes to its position or width. For example, the crimping member 152 is a threaded fastener, threadedly connected to the sealing strip 151, with its lower end abutting against the cover 130. Tightening the threaded fastener changes the pressure exerted by the crimping member 152 on the cover 130, thereby pressing the cover 130 tightly against the mounting portion 111, or allowing it to move relative to the mounting portion 111. When the overall width of the cover 130 can be adjusted by moving the movable portion 132 relative to the cover body 131, the crimping member 152 can press the cover body 131 and the movable portion 132 separately. By tightening the crimping member 152 pressed against the movable portion 132, the movable portion 132 can move relative to the cover body 131, thereby changing the overall width of the cover 130, offering high operational convenience.

[0074] Alternatively, the nozzle 120 can be fixed to the mounting part 111 by screwing a locking member 125 into the second flange 124, with the upper end of the locking member 125 pressing against the bottom surface of the mounting part 111, or by threading it to the bottom of the mounting part 111, thus fixing the nozzle 120 to the mounting part 111. When it is necessary to remove the nozzle 120, the locking member 125 can be unscrewed from the bottom of the nozzle box 100 to release the locking member 125 from the second flange 124. In addition, the crimping member 152 can also be connected to the first flange 123, thereby realizing the connection between the sealing strip 151 and the nozzle 120, so that the sealing strip 151 remains stable after being fixed in the position of the nozzle 120; the connection method between the crimping member 152 and the first flange 123 can be that the crimping member 152 passes through the sealing strip 151, and its lower end is inserted, threaded, or snapped into the first flange 123.

[0075] The length of the air outlet body 122 in the arrangement direction of the mounting portions 111 is less than the minimum distance between the mounting portions 111, that is, there is a gap between the two ends of the air outlet body 122 and the mounting portions 111. If the two mounting portions 111 are defined as arranged along a second direction, then the first direction is perpendicular to the second direction and both are parallel to the horizontal plane. The air outlet body 122 extends along the second direction, and there is a gap between the two ends of the air outlet body 122 in the second direction and the mounting portions 111. When the first flange 123 and the second flange 124 are disconnected from the mounting portions 111, the nozzle 120 can be rotated around the vertical axis, so that the first flange 123 is not obstructed vertically by the mounting portions 111, and the nozzle 120 can be removed from between the two mounting portions 111, making the disassembly and assembly of the nozzle 120 relatively convenient.

[0076] In this invention, sealing gaskets 160 are provided between adjacent protective covers 130, between protective covers 130 and nozzles 120, and between protective covers 130 and sealing partitions 140. The sealing gaskets 160 are flexible and compressible, used to achieve sealing between protective covers 130, between protective covers 130 and nozzles 120, and between protective covers 130 and sealing partitions 140, ensuring that airflow exiting from the air outlet channel only exits through the air outlet 121 of the nozzles 120, preventing air leakage. Furthermore, the sealing gaskets 160 can compensate for positional errors of the protective covers 130, nozzles 120, and sealing partitions 140 after movement, keeping them clamped in the first direction. The number of sealing gaskets 160 can also be increased or decreased to fill gaps between adjacent protective covers 130, between protective covers 130 and nozzles 120, or between protective covers 130 and sealing partitions 140. In addition, a sealing strip 114 is provided on the upper surface of the mounting part 111. The sealing strip 114 is sandwiched between the mounting part 111 and the first flange 123, between the mounting part 111 and the protective cover 130, and between the mounting part 111 and the sealing partition 140, which can further improve the sealing effect of the nozzle box 100.

[0077] In one specific embodiment of the present invention, the second flange 124 is locked to the bottom of the mounting portion 111 by the locking member 125, the sealing strip 151 is connected to the first flange 123 by the pressing member 152, the cover 130 is pressed to the top of the mounting portion 111 by the pressing member 152, and the sealing partition 140 is clamped between adjacent covers 130. When the position of the nozzle 120 needs to be changed, if the adjustment range of the nozzle 120 is small, rotate the crimping member 152 to release the crimping member 152 from pressing the moving part 132, so that the moving part 132 moves relative to the cover body 131, changing the overall width of the cover 130, providing space for the position change of the nozzle 120. Further rotate the crimping member 152 and the locking member 125 to release the lock on the nozzle 120, change the position of the nozzle 120, and finally lock the moving part 132 and the nozzle 120. If the adjustment range of the nozzle 120 is large, rotate the crimping member 152 to remove the cover 130, providing space for the position change of the nozzle 120. Further rotate the crimping member 152 and the locking member to release the lock on the nozzle 120. After moving the nozzle 120 to the required position, replace the cover 130 of the corresponding width or increase or decrease the number of covers 130, and finally lock the cover 130 to the mounting part 111. During the position adjustment of the above-mentioned air nozzle 120, the position of the sealing partition 140 can be changed simultaneously, and the sealing partition 140 can be clamped between the adjacent protective covers 130.

[0078] In this invention, the bottom box 110 also includes a frame 112 and an annular sealing structure 113. The frame 112 has a through mounting cavity, and two mounting parts 111 are respectively connected to two opposite inner walls of the mounting cavity. The sealing structure 113 is connected to the top surface of the frame 112 and is used to cooperate with related structures inside the oven 200 and to seal. The sealing structure 113 surrounds the outside of the sealing partition 140. The sealing structure 113 includes a first sealing part 1131 extending in a first direction and a second sealing part 1132 extending in a second direction. The two ends of the first sealing part 1131 are respectively connected to the two second sealing parts 1132, and the two ends of the second sealing parts 1132 are respectively connected to the two first sealing parts 1131. A sealing cavity is defined between adjacent sealing partitions 140 or between sealing partitions 140 and the second sealing parts 1132, which is used to isolate adjacent air outlet channels and between air outlet channels and the external environment, so that all the airflow in the air outlet channel is introduced into the air nozzle 120 and discharged from the air outlet 121.

[0079] In addition, the top of the frame 112 is provided with a mounting groove 1121, which is used to install the sealing structure 113 and limit the sealing structure 113. A part of the sealing structure 113 protrudes from the top of the mounting groove 1121 to facilitate sealing with other structures.

[0080] Reference Figures 9 to 11The present invention also provides an air outlet device, including the nozzle box 100 in the above embodiment, and an oven 200. The oven 200 has an air outlet cavity 210 and a main air duct 220 inside. The oven 200 is also provided with air guide walls 230 arranged at intervals along a first direction. An air outlet channel 240 is defined between adjacent air guide walls 230. The air outlet cavity 210 is connected to the main air duct 220 through the air outlet channel 240. The nozzle box 100 is disposed in the air outlet cavity 210. When the nozzle box 100 is located inside the air outlet cavity 210, the top of the sealing partition 140 abuts against the air guide wall 230 to isolate adjacent air outlet channels 240. Each air outlet channel 240 is connected to the air outlet 121 of at least one nozzle 120. The airflow in the main air duct 220 is distributed to different air nozzles 120 through each air outlet duct 240. Since the air outlet duct 240 is isolated by the sealed partition 140, the airflow in the air outlet duct 240 can be completely discharged from the air outlet 121 to prevent airflow leakage and turbulence.

[0081] The oven 200 is provided with an inlet and outlet 250 on one side in the first direction. The inlet and outlet 250 is connected to the air outlet 210 and is used to supply air nozzle box 100 to enter and exit the oven 200. The inlet and outlet 250 is provided with an openable and closable door for opening or closing the inlet and outlet 250.

[0082] Reference Figure 12 and Figure 13 The nozzle box 100 has a rotatable roller 170 on its side. The roller 170 is mounted on the bottom box 110. The oven 200 is provided with a guide ramp 260, which is used to guide the roller 170. When the roller 170 rolls along the guide ramp 260, the nozzle box 100 moves in the first direction to enter and exit the oven 200. In addition, along the direction in which the nozzle box 100 enters the air outlet cavity 210, the height of the guide ramp 260 gradually increases. Thus, when the nozzle box 100 enters the oven 200 along the guide ramp 260, the nozzle box 100 is raised, and the sealing partition 140 and the sealing structure 113 can make close contact with the lower surface of the air guide wall 230 in the oven 200, thereby strengthening the contact force between the sealing partition 140, the sealing structure 113 and the air guide wall 230 and improving the sealing effect.

[0083] Furthermore, the guide ramp 260 includes multiple straight sections 261 and multiple inclined sections 262. The upper surface of the straight section 261 is horizontally arranged, and the upper surface of the inclined section 262 gradually rises along the direction in which the air nozzle box 100 enters the oven 200. The straight section 261 and the inclined section 262 are alternately distributed along the first direction. Multiple rollers 170 are arranged along the first direction. When the air nozzle box 100 is located in the air outlet cavity 210, the first inclined section 262 is in contact with at least one roller 170. The direction in which the nozzle box 100 enters the oven 200 is defined as the moving direction. When the roller 170 located at the front of the moving direction passes through different inclined sections 262 in sequence, the position of the nozzle box 100 is raised, so that the sealing partition 140 and the sealing structure 113 can be in close contact with the lower surface of the air guide wall 230. Furthermore, the adjacent straight section 261 and inclined section 262 make the overall transition of the guide ramp 260 smooth, and the rolling of the roller 170 is more stable. On the other hand, when the roller 170 located at the front end in the moving direction contacts the front inclined section 262, the top of each sealing partition 140 contacts the lower surface of an air guide wall 230. As the nozzle box 100 moves forward continuously, under the guidance of the inclined section 262, the squeezing action between the sealing partition 140 and the air guide wall 230 is strengthened, achieving further pre-tightening and improving the sealing effect between the sealing partition 140 and the air guide wall 230.

[0084] In addition, to prevent the nozzle box 100 from moving out of the oven 200 after it has been moved into place, in one embodiment, the oven 200 is also provided with a positioning member to hold the rear end of the nozzle box 100 in the direction of movement, thereby limiting the position of the nozzle box 100 and keeping the nozzle box 100 in a stable position. Furthermore, the oven 200 is also provided with a positioning member to indicate the position of the nozzle box 100. When the nozzle box 100 moves to a preset position in the oven 200, the positioning member abuts against the front end of the nozzle box 100 in the direction of movement, thereby limiting the nozzle box 100 from moving further. Specifically, the oven 200 includes a first positioning member 270 and a second positioning member 280, which are arranged facing each other and abut against opposite ends of the nozzle box 100 along a first direction. For example, the first positioning member 270 is located at the front end of the nozzle box 100 in the moving direction to indicate the moving position of the nozzle box 100, and the second positioning member 280 is located at the rear end of the nozzle box 100 in the moving direction to constrain the nozzle box 100 from exiting the oven 200.

[0085] The air nozzle box 100 also includes an adjusting member 180, with rollers 170 mounted on it. The adjusting member 180 is connected to the side of the base box 110. The adjusting member 180 can change its vertical position to adjust the height of the rollers 170. Understandably, when the air nozzle box 100 is inside the oven 200, rollers 170 at different positions contact different inclined sections 262, and the heights of these different inclined sections 262 are different. By changing the height of the adjusting member 180, the upper surface of the base box 110 can be kept horizontal, ensuring that each sealing partition 140 is in close contact with the corresponding air guide wall 230. That is, along the direction of movement, the heights of different adjusting members 180 decrease sequentially, and the height difference between adjacent adjusting members 180 is equal to the height difference between adjacent rollers 170.

[0086] The side wall of the base box 110 is provided with a waist-shaped hole. The adjusting member 180 is locked in the waist-shaped hole by a threaded fastener. The height of the adjusting member 180 can be changed by adjusting the locking position of the threaded fastener in the waist-shaped hole. In addition, the side of the base box 110 is also provided with an abutment member 190. The abutment member 190 abuts against the top of the adjusting member 180 to further stabilize the height position of the adjusting member 180 and prevent the adjusting member 180 from loosening or changing position due to the adjustment of the roller 170.

[0087] The process of the air nozzle box 100 entering and exiting the oven 200 is as follows: Place the air nozzle box 100 on the top of the lifting trolley 300, open the door at the inlet and outlet 250, adjust the height of the lifting trolley 300 so that the height of the air nozzle box 100 corresponds to that of the inlet and outlet 250, push the air nozzle box 100 into the oven 200, and the roller 170 rolls along the guide ramp 260. When the air nozzle 120 moves to the approximate position, the roller 170 contacts the inclined section 262, and the air nozzle box 100 rises along the inclined section 262. The sealing partition 140 and the sealing structure 113 press against the air guide wall 230 to form a seal. At the same time, the air nozzle box 100 is positioned by the first positioning member 270. Then, the second positioning member 280 is locked so that the second positioning member 280 abuts against the air nozzle box 100 and the inlet and outlet 250 are closed, completing the process of pushing the air nozzle box 100 into the oven 200. When the position of the air nozzle 120 needs to be adjusted, the oven 200 stops operating, the inlet and outlet 250 is opened, the height of the lifting trolley 300 is aligned with the inlet and outlet 250, the air nozzle box 100 is pulled out from the oven 200 onto the lifting trolley 300, the position of the air nozzle 120 is adjusted, and a seal is formed between the air nozzle 120 and the protective cover 130, between adjacent protective covers 130, and between the protective cover 130 and the sealing partition 140, and then the air nozzle box 100 is pushed back into the oven 200.
