The return air pipe 202 extends to the left and right to the whole width, and meets the film dehumidification requirement of a large extent (6-10 meters).

In the second embodiment, referring to fig. 1 to 7, based on the first embodiment, considering that the width dimension of the tuyere 4 is usually fixed when the tuyere 4 is used, the width of the tuyere entering the film in the housing 7 is often unequal, so that the leftmost side and the rightmost side of the tuyere 4 are not usually corresponding to the film, and at this time, the effective utilization of the air outlet of the tuyere cannot be realized, and a certain limitation of use exists.
For this purpose, the tuyere 4 is improved in that the tuyere 4 comprises two side plates 401 fixedly connected with the telescopic tube 3 and corresponding to each other in front and back, two partition plates 402 corresponding to each other in left and right are slidably installed between the two side plates 401, a baffle 403 for blocking air outlet is fixedly installed at the top of each partition plate 402, and the baffle 403 can extend out from the side surface of the side plate 401 and can be located on the top surface of the base 502 without interference with the base 502. By the above design, the air flow through the telescopic tube 3 can only be discharged from between the two baffles 402.
Referring to fig. 6 and 7, in the present embodiment, it is preferable that the insert 505 includes a quadrangular block 5051 slidably engaged with both the base 502 and the chute 506, and the quadrangular block 5051 is internally screw-sleeved with a strut 5052 rotatably engaged with the partition 402, and the partition 402 is driven to move left and right along the side plate 401 by rotation of the strut 5052 in the quadrangular block 5051, thereby adjusting the interval between the adjacent two partitions 402.
Wherein, quadrilateral piece 5051 makes baffle 402 can not take place to rotate based on pillar 5052, avoids the slope of baffle 402 and curb plate 401, guarantees that the tuyere 4 that curb plate 401 and baffle 402 formed can provide the effect of directly blowing to the film. In order to avoid the side plate 401 and the partition plate 402 from rotating automatically when the hot air flows, a telescopic rod (not shown in the figure) can be mounted between the quadrilateral block 5051 and the partition plate 402, and the telescopic rod can enable the partition plate 402 to move left and right only, so that the side plate 401 can be oriented.
In the above structure, the partition 402 near one side of the trough 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, so that the baffle 403 needs to be manually pulled to adjust by opening the housing 7.
When in use, through the structures of the base 502, the insert 505, the telescopic pipe 3 and the like, the corresponding adjustment of the tuyere 4 in the up-down direction and the front-back direction can be realized, so that the tuyere 4 can be effectively matched with a film to be processed, and the working process and the effect of the part are the same as those of the first embodiment, and the repeated description is omitted. The difference is that when the side plate 401 and the partition plate 402 are driven to be adjusted up and down and adjusted back and forth by the first air cylinder 501 and the second air cylinder 503, the partition plate 402 can be moved along the side plate 401 by rotating the support 5052 based on the insert 505, and the left-right distance between the two partition plates 402 is adjusted to be effectively matched with the left-right width of the film, so that the positions of the side plate 401 on two sides of the film are blocked by the baffle 403. When the subsequent air inlet pipe 201 discharges air through the telescopic pipe 3, the air flow can only be discharged from between the two partition plates 402 and blown to the film, and the positions on two sides are blocked by the baffle plates 403 and cannot discharge air.
Compared with the first embodiment, through the cooperation of structures such as the side plate 401, the partition plate 402, the quadrilateral block 5051 and the support 5052, the left-right spacing adjustment between two adjacent partition plates 402 can be realized, the left-right width of the film to be processed can be effectively adapted, the invalid air outlet on the left side and the right side of the film is avoided, the air flow can be completely blown to the film for processing, the utilization rate of the air flow resource can be further ensured, and the film processing device is also applicable to films with different widths. The overall scheme combines with the design of the tuyere 4 and the insert 505, and does not affect the up-down and back-and-forth adjustment of the side plates 401 and the partition plate 402, so that the applicability is stronger.
Referring to fig. 1 to 10, in the third embodiment, considering that the adjustment of the partition 402 on the side far from the trough plate 504 is difficult, and the partition 402 after the adjustment of the strut 5052 is offset from the right-left direction center position, the position of the film needs to be adjusted, which has disadvantages.
For this purpose, the adjustment of the two partition boards 402 is improved, wherein a moving component 6 is commonly arranged between the two partition boards 402 and the two side boards 401, and the two partition boards 402 can be synchronously relatively close to or relatively far away from each other through the moving component 6, so that the partition boards 402 are left-right symmetrical based on the center of the left-right direction after the position adjustment, and the position of the film is not adjusted again.

Furthermore, the gear 603 and the rack 604 are both arranged at the position of the outer surface of the side plate 401 close to the lower side, namely, the position of obliquely guiding the air outlet, so that the position of the lower side of the side plate 401 can be bonded and protected by design, the lower side of the side plate 401 is prevented from bending and deforming in the long-term hot air discharging process, the service cycle of the side plate 401 is further ensured, the bonding and sealing effects of the side plate 401 and the partition plate 402 can be ensured, and the dissipation of hot air flow in discharging can be avoided.
In order to ensure the same protection effect on the two side plates 401, the cantilever 602 is provided with two end parts, wherein one end part extends to the lower side of the front surface of the front side plate 401, the other end part extends to the lower side of the rear surface of the rear side plate 401, and the upper and lower positions of the two end parts are staggered, so that the two cantilever 602 can provide the same attaching effect on the side plates 401 on the basis of not affecting the meshing transmission of the gear 603 and the rack 604.
When the film processing device is used, through the structures of the base 502, the embedded block 505, the telescopic pipe 3 and the like, the corresponding adjustment of the air nozzle 4 in the up-down direction and the front-back direction can be realized, so that the air nozzle 4 can be effectively matched with the film to be processed, through the structures of the side plates 401, the partition plates 402, the quadrilateral blocks 5051 and the like, the left-right spacing adjustment between the two adjacent partition plates 402 can be realized, the left-right width adjustment of the film to be processed can be effectively matched with the left-right width of the film to be processed, and the working process and the effect of the part are the same as those of the second embodiment, and the repeated description is omitted. The difference is that when the rotating support 5052 moves the position of the partition plate 402 based on the side plate 401, the partition plate 402 can drive the right guide post 601 to move synchronously, the right guide post 601 drives the corresponding rack 604 to move through the cantilever 602, the rack 604 can drive the other cantilever 602 and the other guide post 601 to move synchronously through the gear 603, so that the two partition plates 402 are synchronously relatively close to or relatively far away from each other, and at the moment, the left-right direction center of the two partition plates 402 is still the left-right direction center of the side plate 401.
