By installing the air guide pipe at the lower end of the air guide housing, installing the lifting members on both sides of the air guide housing, arranging the hanging member on the upper part of the air guide housing, connecting the hanging member to the lifting member, and the hanging member being located above the lifting member, the distance between the air nozzle and the foil to be dried can be adjusted, and the wind speed can be adjusted through the air guide pipe. This structure is simple and ingenious, easy to install, and conducive to reducing structural size and energy consumption.

[0004] This application uses hanging parts and lifting parts to achieve the up and down movement of the nozzle, and then adjusts the upper and lower distance between the foil.

[0031] Example 1: Please refer to Figures 1 to 4 An embodiment of the present invention provides an oven device for an online coating device, which is mainly used to achieve height adjustment and spacing adjustment of the position of the air nozzle 4. The device includes a shell 7, and two corresponding static pressure boxes 1 are fixedly installed inside the shell 7. A space is left between the two static pressure boxes 1 for the film to pass through. The opposite sides of the two static pressure boxes 1 are connected to the air nozzle 4 through a telescopic tube 3; wherein the number of the air nozzles 4 is set to four and is arranged in a front-to-back array based on the static pressure boxes 1.

[0032] In this embodiment, the flexible telescopic tube 3 allows for vertical and longitudinal position adjustment of the nozzle 4, thereby enabling adjustment of the nozzle 4. Vertical adjustment provides an appropriate blowing force on the film, preventing damage to the film and ensuring effective blowing. Fore-and-aft adjustment provides an appropriate spacing between adjacent nozzles 4, further ensuring effective blowing and preventing turbulent airflow between the nozzles 4.

[0033] Furthermore, an adjustment assembly 5 for driving the movement of the air nozzle 4 is provided on the side wall of the static pressure box 1. The adjustment assembly 5 can realize the height adjustment and spacing adjustment of the air nozzle 4 relative to the static pressure box 1. The interior of the housing 7 is also provided with an air duct 2 connected to the static pressure box 1. The air duct 2 can realize the supply of air to the static pressure box 1 and the return of air in the housing 7.

[0034] Reference Figure 2 and Figure 3 In this embodiment, the adjustment assembly 5 preferably includes a first cylinder 501 fixedly connected to the static pressure box 1 and an insert 505 for driving the air nozzle 4 to move. The output shaft of the cylinder is fixedly mounted with a base 502 for the insert 505 to slide. The side wall of the base 502 is fixedly mounted with a second cylinder 503. The output shaft of the second cylinder 503 is fixedly mounted with a slot plate 504 for the insert 505 to slide. The first cylinder 501 and the second cylinder 503 both move up and down. The first cylinder 501 is used to drive the base 502 and the second cylinder 503 to move up and down, while the second cylinder 503 is used to drive the slot plate 504 to move up and down.

[0035] In the above structure, the insert 505 slides back and forth on the base 502. The up and down movement of the base 502 drives the insert 505 up and down synchronously. The surface of the groove plate 504 is provided with a slide groove 506 for the slide of the insert 505. When the second cylinder 503 drives the groove plate 504 up and down, the slide groove 506 drives the insert 505 to slide back and forth. Specifically, the slide groove 506 is designed as an inclined straight line, but other shapes can be used as long as they can enable the insert 505 to move back and forth with equal spacing.

[0036] In this embodiment, the insert 505 is fixedly connected to the side wall of the nozzle 4, so that when the insert 505 moves, the nozzle 4 can be moved synchronously. The base 502 is designed as a whole in a T shape, with its vertical portion being used to house the second cylinder 503 and its horizontal portion being used for the left and right sliding of the insert 505.

[0037] Reference Figure 1 and Figure 4 In this embodiment, preferably, the air duct 2 includes two air inlet ducts 201 and two air return ducts 202. The two air inlet ducts 201 are respectively connected to the two static pressure boxes 1. One of the return air ducts 202 is fixedly installed on the top of one of the static pressure boxes 1, and the other return air duct 202 is fixedly installed on the bottom of the other static pressure box 1 to ensure better space utilization.

[0038] In this embodiment, both the air inlet duct 201 and the air return duct 202 extend outside the housing 7 and connect to an external fan (not shown) for air supply and return. The air return duct 202 extends across the entire width of the membrane, meeting the moisture removal requirements of a wide range (6-10 meters).

[0039] During use, the film enters the housing 7 and is positioned between the upper and lower rows of nozzles 4. The external fan is activated to discharge air toward the nozzles 4 through the air inlet duct 201, the static pressure box 1, and the telescopic tube 3, ensuring uniform heating of the coating film. Simultaneously, the airflow within the housing 7 can be discharged through the return air duct 202, ensuring adequate dehumidification. Before use, the first cylinder 501 can be activated to synchronously raise and lower the base 502, the second cylinder 503, and the slot plate 504, thereby driving the nozzles 4 up and down in a corresponding manner via the insert 505. Alternatively, the second cylinder 503 can be activated to raise and lower the slot plate 504. At this point, the base 502 no longer moves, and the insert 505 can be driven by the slide 506 to move left and right along the base 502, thereby enabling corresponding adjustment of the nozzles 4 in the forward and backward directions. During this process, the telescopic tube 3 can also move accordingly, ensuring rapid adjustment of the nozzles 4.

[0040] To sum up, through the cooperation of structures such as the base 502, the insert 505, the groove plate 504 and the telescopic tube 3, the corresponding adjustment of the air nozzle 4 in the up and down directions and the front and back directions can be achieved, so that the up and down spacing between the air nozzle 4 and the film, as well as the front and back spacing between adjacent air nozzles 4, can be effectively adapted to the film to be processed, thereby ensuring the processing effect and processing efficiency of the film, and can be effectively applied to the use of films with different parameters; the overall structure is simple and the space utilization rate is higher, and the utilization rate of the air flow resources in the shell 7 is also higher. At the same time, the adjustable range of the air nozzle 4 is larger due to the design of the telescopic tube 3, and it has higher practicality.

[0041] Example 2: Please refer to Figures 1 to 7 On the basis of Example 1, considering that the left and right widths of the air nozzle 4 are usually fixed when in use, the left and right widths of the film entering the shell 7 are often not equal, so that the leftmost and rightmost sides of the air nozzle 4 usually do not correspond to the film. At this time, this part of the air outlet cannot be effectively utilized, and there are certain limitations on its use.

[0042] To this end, the nozzle 4 is improved: it now includes two side panels 401 fixedly connected to the telescopic tube 3 and corresponding to each other in front and back. Two partitions 402, corresponding to each other in the left and right, are slidably mounted between the two side panels 401. A baffle 403 is fixedly mounted on the top of the partitions 402 to block the outflow of air. The baffle 403 can extend from the side of the side panels 401 and can be located on the top surface of the base 502 without interfering with the base 502. This design ensures that airflow through the telescopic tube 3 can only be discharged from between the two partitions 402.

[0043] Reference Figure 6 and Figure 7 In this embodiment, preferably, the insert 505 includes a quadrilateral block 5051 that slides with the base 502 and the slide groove 506, and the internal threaded sleeve of the quadrilateral block 5051 is provided with a pillar 5052 that rotates with the partition 402. Through the rotation of the pillar 5052 on the quadrilateral block 5051, the partition 402 can be driven to move left and right along the side plate 401, thereby adjusting the distance between two adjacent partitions 402.

[0044] The quadrilateral blocks 5051 prevent the partitions 402 from rotating relative to the support 5052, thus preventing the partitions 402 and side panels 401 from tilting and ensuring that the air nozzles 4 formed by the side panels 401 and partitions 402 provide a direct blow effect on the film. To prevent the side panels 401 and partitions 402 from rotating when the hot air flow blows, a telescopic rod (not shown) can be installed between the quadrilateral blocks 5051 and the partitions 402. The telescopic rod restricts the partitions 402 to left and right movement, thereby also providing a directional effect on the side panels 401.

[0045] In the above structure, the partition 402 close to the groove plate 504 can be adjusted by the support 5052, and the partition 402 and the baffle 403 on the other side are in a relatively fixed state, and the shell 7 needs to be opened to manually pull the baffle 403 for adjustment.

[0046] During use, the nozzle 4 can be adjusted vertically and forward and backward through the base 502, insert 505, and telescopic tube 3, allowing it to effectively adapt to the film being processed. The working process and effects of this portion are the same as those in Example 1 and will not be repeated here. The difference is that while the side panels 401 and partitions 402 are adjusted vertically and forward and backward by the first and second cylinders 501 and 503, the insert 505 can also be used to rotate the support 5052 to move the partitions 402 along the side panels 401, thereby adjusting the left-right spacing between the two partitions 402 to effectively adapt to the left-right width of the film, so that the side panels 401 on both sides of the film are blocked by the baffles 403. When the air inlet 201 subsequently discharges air through the telescopic tube 3, the airflow can only be discharged from between the two partitions 402 and blown toward the film, while the airflow on both sides is blocked by the baffles 403 and cannot be discharged.

[0047] Compared to the first embodiment, the coordination of the side panels 401, partitions 402, quadrilateral blocks 5051, and struts 5052 allows for adjustment of the left-right spacing between adjacent partitions 402, effectively adapting to the left-right width of the film being processed. This prevents ineffective airflow from the left and right sides of the film, allowing the entire airflow to be directed toward the film for processing. This further ensures efficient utilization of airflow resources and is equally applicable to films of varying widths. This overall solution, combined with the design of the nozzle 4 and insert 505, does not affect the vertical and forward and backward adjustment of the side panels 401 and partitions 402, resulting in greater applicability.

[0048] Example 3: Please refer to Figures 1 to 10 On the basis of Example 2, considering that the partition 402 on the side away from the groove plate 504 is more difficult to adjust, and although the partition 402 after the adjustment of the support 5052 realizes the left and right spacing adjustment, it also deviates from the center position in the left and right directions, and the position of the film also needs to be adjusted, it still has shortcomings.

[0049] To this end, the adjustment of the two partitions 402 is improved: at this time, a moving component 6 is commonly provided between the two partitions 402 and the two side plates 401. The moving component 6 can realize the synchronous relative approach or relative distance of the two partitions 402, so that the partitions 402 are still symmetrical based on the center in the left and right directions after the position adjustment, and it is invalid to adjust the position of the film again.

[0050] Reference Figure 9 and Figure 10In this embodiment, preferably, the moving component 6 includes a guide column 601 fixedly connected to the side plate 401 and a gear 603 rotatably installed on the side plate 401, and the end of the guide column 601 away from the partition 402 is fixedly installed with a cantilever 602 that movably fits with the side plate 401, and the surface of the cantilever 602 is fixedly installed with a rack 604 that is transmission-connected to the gear 603, and the racks 604 on the two cantilevers 602 are symmetrically staggered, so that when one of the cantilevers 602 approaches the side plate 401, the rack 604 and the gear 603 can drive the other cantilever 602 to approach the side plate 401 synchronously, thereby realizing the synchronous relative approach or relative distance of the two guide columns 601.

[0051] Furthermore, the gear 603 and the rack 604 are both arranged on the outer surface of the side panel 401 near the lower side, that is, the position where the air outlet is inclined. This design can fit and protect the lower side of the side panel 401, avoiding bending and deformation of the lower side of the side panel 401 during long-term hot air discharge, thereby ensuring the service life of the side panel 401; it can also ensure the fitting and sealing effect of the side panel 401 and the partition 402, avoiding the escape of hot air flow during discharge.

[0052] In order to ensure the same protective effect on the two side panels 401, the cantilever 602 is provided with two ends, one end extends to the lower side of the front surface of the front side panel 401, and the other end extends to the lower side of the rear surface of the rear side panel 401, and the upper and lower positions of the two ends are staggered, without affecting the meshing transmission of the gear 603 and the rack 604, so that the two cantilevers 602 can provide the same fitting effect on the side panels 401.

[0053] During use, the nozzle 4 can be adjusted in the up and down directions and the front and back directions through structures such as the base 502, the insert 505 and the telescopic tube 3, so that the nozzle 4 can be effectively adapted to the film to be processed; through structures such as the side panels 401, the partitions 402 and the quadrilateral blocks 5051, the left and right spacing between two adjacent partitions 402 can be adjusted, which can effectively adapt to the left and right widths of the film to be processed. The working process and effects of this part are the same as those in Example 2 and will not be repeated here. The difference is: when the rotating pillar 5052 moves the position of the partition 402 based on the side plate 401, the partition 402 can drive the right guide column 601 to move synchronously, and the right guide column 601 drives the corresponding rack 604 to move through the cantilever 602, and the rack 604 can drive another cantilever 602 and another guide column 601 to move synchronously through the gear 603, thereby making the two partitions 402 relatively close or relatively far away from each other synchronously. At this time, the left and right centers of the two partitions 402 are still the left and right centers of the side plate 401.

[0054] Compared to Example 2, the coordination of structures such as the partition 402, guide post 601, cantilever 602, and gear 603 allows the two partitions 402 to be synchronously moved closer or further apart, so that after adjustment, the centers of the two partitions 402 always correspond to the centers of the side panels 401. At this point, the position between the two partitions 402 can always correspond to the film, and there is no need to adjust the position of the film. The overall design is combined with the arrangement of the partitions 402 and side panels 401, and can reduce the bending deformation of the side panels 401 during long-term use, ensuring that the hot air flow is fully directed toward the film, further ensuring the effective utilization of airflow resources and the processing effect of the film, and meeting more needs in actual use.
