DETAILED DESCRIPTION

[0021] 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.

[0022] In this embodiment, the telescopic tube 3 is flexible, and the position of the air nozzle 4 can be adjusted in the up-down direction and the front-back direction, thereby adjusting the position of the air nozzle 4. The adjustment in the up-down direction can provide a suitable blowing force for the film, avoid damage to the film and ensure the blowing effect; and the front-back adjustment can provide a suitable spacing between two adjacent air nozzles 4, which can further ensure the blowing effect and avoid turbulent disturbance of the air flow between the air nozzles 4.

[0023] Furthermore, an adjustment component 5 for driving the movement of the air nozzle 4 is provided on the side wall of the static pressure box 1, and the height and spacing of the air nozzle 4 based on the static pressure box 1 can be adjusted by adjusting the component 5. Among them, the shell 7 is also provided with an air duct 2 connected to the static pressure box 1, and the air supply to the static pressure box 1 and the return of the air flow in the shell 7 can be realized through the air duct 2.

[0024] Reference Figure 2 and Figure 3 In this embodiment, preferably: the adjustment component 5 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 installed with a base 502 for the insert 505 to slide, the side wall of the base 502 is fixedly installed with a second cylinder 503, and the output shaft of the second cylinder 503 is fixedly installed with a slot plate 504 for the insert 505 to slide. Among them, the first cylinder 501 and the second cylinder 503 are both moved up and down, the first cylinder 501 is used to drive the base 502 and the second cylinder 503 to move up and down, and the second cylinder 503 is used to drive the slot plate 504 to move up and down.

[0025] In the above structure, the insert 505 slides forward and backward based on the base 502, and the up and down movement of the base 502 can drive the insert 505 to move up and down synchronously. The surface of the groove plate 504 is provided with a slide groove 506 for the insert 505 to slide. When the second cylinder 503 drives the groove plate 504 to move up and down, the slide groove 506 can drive the insert 505 to slide forward and backward; specifically, the slide groove 506 is an inclined straight-line design, and of course other shapes can be used as long as the insert 505 can move forward and backward with equal spacing.

[0026] In this embodiment, the insert 505 is fixedly connected to the side wall of the nozzle 4, so that when the insert 505 moves, it can drive the nozzle 4 to move synchronously. The base 502 is designed in a T shape as a whole, and its vertical part is used for the placement of the second cylinder 503, and its horizontal part is used for the left and right sliding of the insert 505.

[0027] 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.

[0028] In this embodiment, the air inlet duct 201 and the air return duct 202 are both extended to the outside of the housing 7 and connected to an external fan for air inlet and air return, and the external fan is not shown in the figure. The air return duct 202 extends to the entire width to meet the large-scale (6-10 meters) film dehumidification requirements.

[0029] When in use, the film enters the housing 7 and is located between the upper and lower rows of nozzles 4. The external fan is started to discharge air to the nozzles 4 through the air inlet pipe 201, the static pressure box 1 and the telescopic tube 3 to ensure that the coating film is heated evenly. At the same time, the airflow in the housing 7 can be discharged through the return air pipe 202 to ensure sufficient dehumidification. Before use, the first cylinder 501 can be started to drive the base 502, the second cylinder 503 and the slot plate 504 to rise and fall synchronously, and then the nozzle 4 can be driven to rise and fall in the up and down directions through the insert block 505; the second cylinder 503 can also be started to drive the slot plate 504 to rise and fall. At this time, the base 502 no longer moves, and the insert block 505 can be driven to move left and right along the base 502 through the slide slot 506, thereby realizing the corresponding adjustment of the nozzle 4 in the front and back directions; in this process, the telescopic tube 3 can move accordingly to ensure the rapid adjustment of the nozzle 4.

[0030] To summarize, through the coordination 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 efficiency of the film, and can be effectively applied to the use of films with different parameters; the overall structure is concise 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.

[0031] Example 2: Please refer to Figures 1 to 7 On the basis of the first embodiment, 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 in use.

[0032] To this end, the air nozzle 4 is improved: the air nozzle 4 now includes two side panels 401 fixedly connected to the telescopic tube 3 and corresponding to each other in the front and back, two partitions 402 corresponding to each other in the left and right are slidably installed between the two side panels 401, and a baffle 403 for blocking the air flow is fixedly installed on the top of the partition 402; the baffle 403 can extend from the side of the side panel 401 and can be located on the top surface of the base 502 without interfering with the base 502. Through the above design, the airflow can only be discharged from between the two partitions 402 after passing through the telescopic tube 3.

[0033] Reference Figure 6 and Figure 7 In this embodiment, preferably: the insert 505 includes a quadrilateral block 5051 that is slidably matched 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 is rotatably matched 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.

[0034] The quadrilateral block 5051 prevents the partition 402 from rotating based on the pillar 5052, thereby preventing the partition 402 and the side plate 401 from tilting, and ensuring that the air nozzle 4 formed by the side plate 401 and the partition 402 can provide a direct blowing effect on the film. In order to prevent the side plate 401 and the partition 402 from self-rotating when the hot air flow blows, a telescopic rod (not shown in the figure) can be installed between the quadrilateral block 5051 and the partition 402. The telescopic rod allows the partition 402 to move only left and right, thereby also having a directional effect on the side plate 401.

[0035] In the above structure, the partition 402 close to the slot plate 504 can be adjusted by the support 5052, while 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.

[0036] When in use, the corresponding adjustment of the nozzle 4 in the up-down direction and the front-back direction can be realized through the 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. The working process and effect of this part are the same as those in the first embodiment, and will not be repeated here. The difference is that when the side plate 401 and the partition 402 are driven to adjust up and down and front and back by the first cylinder 501 and the second cylinder 503, the support 5052 can also be rotated based on the insert 505 to make the partition 402 move along the side plate 401, and then the left-right spacing between the two partitions 402 is adjusted to effectively adapt to the left-right width of the film, so that the position of the side plate 401 on both sides of the film is blocked by the baffle 403. When the air inlet pipe 201 discharges air through the telescopic tube 3, the airflow can only be discharged from between the two partitions 402 and blown to the film, while the positions on both sides are blocked by the baffle 403 and cannot discharge air.

[0037] Compared with the first embodiment, the left-right spacing between two adjacent partitions 402 can be adjusted through the coordination of the side panels 401, the partitions 402, the quadrilateral blocks 5051 and the pillars 5052, which can effectively adapt to the left-right width of the film to be processed, avoiding ineffective airflow on the left and right sides of the film, so that the airflow can be blown to the film for processing, further ensuring the utilization rate of airflow resources, and also applicable to films of different widths. The overall solution is combined with the design of the air nozzle 4 and the insert 505, and will not affect the up-down and front-back adjustment of the side panels 401 and the partitions 402, and has stronger applicability.

[0038] Example 3: Please refer to Figures 1 to 10 On the basis of the second embodiment, considering that the partition 402 far from the side of the slot plate 504 is 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.

[0039] 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, and 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 is adjusted, and it is invalid to adjust the position of the film.

[0040] Reference Fig. 9 and Fig.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 is movably fitted 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 cantilever 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.

[0041] 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 provide a close protection for the lower side of the side panel 401, thereby preventing the lower side of the side panel 401 from bending and deforming during long-term hot air discharge, thereby ensuring the service life of the side panel 401; it can also ensure the close sealing effect between the side panel 401 and the partition 402, thereby preventing the hot air flow from escaping during discharge.

[0042] In order to ensure the same protective effect on the two side panels 401, the cantilever 602 is provided with two ends, one of which 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, so that the two cantilevers 602 can provide the same fitting effect on the side panels 401 without affecting the meshing transmission of the gear 603 and the rack 604.

[0043] When in use, the corresponding adjustment of the air nozzle 4 in the up and down directions and the front and back directions can be achieved through the structures such as the base 502, the insert block 505 and the telescopic tube 3, so that the air nozzle 4 can be effectively adapted to the film to be processed; through the 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-right center of the two partitions 402 is still the left-right center of the side plate 401.

[0044] Compared with the second embodiment, through the coordination of the structures such as the partition 402, the guide column 601, the cantilever 602 and the gear 603, the two partitions 402 can be synchronously relatively close or far away, so that the centers of the two partitions 402 and the center of the side plate 401 are always kept corresponding after adjustment. At this time, the position between the two partitions 402 can always keep corresponding to the film, and there is no need to adjust the position of the film. The overall design is combined with the setting of the partition 402 and the side plate 401, and the bending deformation of the side plate 401 during long-term use can be reduced, ensuring that the hot air flow can be fully guided to blow toward the film, further ensuring the effective use of air flow resources and the processing effect of the film, and meeting more needs in actual use.
