[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a hot air drying oven for preventing sticking of cellulose film includes: a box body 20, which is a hollow box with a front wall that can be flipped open; a hot air blower assembly 21 is installed on the top of the box body 20; the air outlet of the hot air blower assembly 21 can communicate with the top of the cavity of the box body 20; the hot air blower assembly 21 is electrically connected to a power source; and a handle for fixing is installed on the front wall of the box body 20. This is existing technology and will not be described in detail here.
[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the film-hanging structure is set inside the cavity of the box 20 for hanging film. The film-hanging structure includes: upper frame 34, side rods 36, partition plate 33, handle 40 and hanging rod 41. The upper frame 34 is set inside the cavity of the box 20. The side rods 36 are symmetrically fixedly connected to the wall of the upper frame 34. The partition plate 33 is fixedly connected to the wall of the upper frame 34. The handle 40 is detachably connected to the top of the upper frame 34. The hanging rod 41 is fixedly connected to the bottom of the handle 40. The wall of the hanging rod 41 can hang the film to be dried.
[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4and Figure 5 As shown, the upper frame 34 and side rod 36 are rectangular rods. The front wall of the side rod 36 is also provided with the same upper frame 34. The symmetrical upper frame 34 and side rod 36 can form a rectangular frame. The partition plate 33 is located between the symmetrical upper frames 34. Multiple identical partition plates 33 are evenly arranged between the symmetrical upper frames 34. The partition plate 33 is a rectangular plate. Multiple rectangular slots are symmetrically opened on both sides of each partition plate 33. The handle 40 is a rectangular rod. The hanging rod 41 is a U-shaped rod with the opening facing upward. The top of each upper frame 34 is provided with the same handle 40. Multiple identical hanging rods 41 are evenly arranged between the symmetrical handles 40. Each hanging rod 41 is located between adjacent partition plates 33. The membrane hanging structure also includes a fixed rail 30, a sliding rod 31, a slot 32, a slot 35 and a pocket plate 37. The fixed rail 30 is symmetrically fixedly connected to the two sides of the cavity of the box body 20. On the side, the slide rod 31 is slidably connected between symmetrical fixed rails 30. A rectangular bracket is fixedly connected to the top center of the slide rod 31. The top of the rectangular bracket can be fixedly connected to the bottom of the upper frame 34 behind. The slots 32 are symmetrically opened on both sides of the slide rod 31. The slots 35 are opened on the top of each upper frame 34. The pocket plate 37 is fixedly connected to the bottom of all the partition plates 33. The fixed rail 30 is a T-shaped rod. The fixed rail 30 is horizontally placed on the inner side wall of the cavity of the box 20. The slide rod 31 is engaged with the wall of the symmetrical fixed rail 30 through the slots 32 on both sides. A rectangular groove is opened on the side wall of the box 20 above each fixed rail 30. The pocket plate 37 is a rectangular plate. Multiple identical arc-shaped grooves are opened on the top of the pocket plate 37. Each groove on the top of the pocket plate 37 is located directly below each hanging rod 41. Multiple identical round holes are opened on the top of the pocket plate 37.
[0030] In practical use, first, the front wall of the box 20 is flipped open using the opening handle. Then, the upper frame 34 is pulled. When the upper frame 34 is pulled, the sliding rod 31 will slide along the symmetrical fixed rails 30 towards the outer wall. At this time, the upper frame 34 will cause all the structures on its wall to extend out of the cavity of the box 20. The side rod 36 will slide synchronously along the rectangular groove in the cavity of the box 20. After the upper frame 34 is pulled out, the hanging rod 41 will be misaligned with the cavity of the box 20. At this time, the cellulose film to be dried is hung one by one in the top opening of each hanging rod 41. Then, the upper frame 34 is pushed into the cavity of the box 20. Finally, the upper frame 34 is fully inserted into the box. After the body 20 cavity is filled, the front wall of the box 20 can be closed and the hot air blower assembly 21 can be turned on. At this time, the hot air blower assembly 21 will continuously deliver hot air into the box 20 cavity. The hot air will move from top to bottom in the box 20 cavity. The hot air blown by the hot air blower assembly 21 will pass through the adjacent partition plates 33 and contact the film hanging on the wall of the hanging rod 41 and dry it. After drying, the upper frame 34 can be pulled outward through the above opening steps and then the handle 40 can be lifted upward. The handle 40 can drive the hanging rod 41 to separate from the wall of the upper frame 34 at the same time. The bottom of the handle 40 is fixedly connected with a rectangular block for engaging with each slot 35.
[0031] In summary, by setting up a film hanging structure and utilizing the individually detachable handles 40 and hanging rods 41, each batch of cellulose film can be hung and removed simultaneously. This not only saves a lot of time, but also, in conjunction with each guide plate 33, enables centralized drying of each cellulose film while preventing adjacent cellulose films from sticking together.
[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a collection box 22 is snapped into the bottom of the cavity of the box 20. The collection box 22 is a hollow rectangular box with an open top. The top opening of the collection box 22 is aligned with the bottom of the pocket 37. A ventilation pipe 23 is symmetrically and fixedly connected to the rear wall of the box 20. The ventilation pipe 23 is an L-shaped round pipe. The bottom opening of the ventilation pipe 23 can communicate with the rear wall of the cavity of the box 20. The connection between the ventilation pipe 23 and the box 20 is located below the pocket 37.
[0033] In actual use, the liquid dripping from the cellulose film wall hanging on the hanging rod 41 will be collected from the round hole at the top of the pocket plate 37 into the cavity of the collection box 22, while the ventilation pipe 23 can guide the hot air in the cavity of the box 20 to be discharged.
[0034] In summary, by setting up the flap 37, the problem of cellulose film falling from the wall of the hanging rod 41 into the cavity of the box 20 can be prevented, while the collection box 22 and the ventilation pipe 23 can prevent liquid accumulation in the cavity of the box 20 and facilitate ventilation in the cavity of the box 20.
[0035] Working principle: First, the front wall of the box 20 is flipped open using the opening handle. Then, the upper frame 34 is pulled. When the upper frame 34 is pulled, the sliding rod 31 will slide along the symmetrical fixed rails 30 towards the outer wall. At this time, the upper frame 34 will cause all the structures on its wall to extend out of the cavity of the box 20. The side rod 36 will slide synchronously along the rectangular groove in the cavity of the box 20. After the upper frame 34 is pulled out, the hanging rod 41 will be misaligned with the cavity of the box 20. At this time, the cellulose film to be dried is hung one by one on the top of each hanging rod 41. In the opening, push the upper frame 34 into the cavity of the box 20. After the upper frame 34 is fully inside the cavity of the box 20, close the front wall of the box 20 and turn on the hot air blower assembly 21. At this time, the hot air blower assembly 21 will continuously deliver hot air into the cavity of the box 20. The hot air will move from top to bottom inside the cavity of the box 20. The hot air blown by the hot air blower assembly 21 will pass through the adjacent partition plates 33 and contact the film hanging on the wall of the hanging rod 41 and dry it. The ventilation pipe 23 can guide the hot air in the cavity of the box 20 to be discharged.
