[0028] The energy-saving fabric drying oven proposed by this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0029] Reference Figures 1-4 This utility model provides an energy-saving fabric drying oven, including a drying box 1 for drying fabric. The drying box 1 has openings 2 on both sides. Three guide rollers 3 for guiding the fabric are rotatably connected to the inner walls of the front and rear sides of the drying box 1. Several heating tubes 40 are provided inside the drying box 1. A spacing adjustment mechanism 4 is provided between the heating tubes 40 and the drying box 1. A fan 6 is fixedly connected to the front side of the drying box 1. An air outlet pipe 7 is fixedly connected to one side of the fan 6. A dehumidification box 8 is fixedly connected to one end of the air outlet pipe 7. The dehumidification box 8 and the front side of the drying box 1 are fixedly connected to the same return pipe 10. A controller is fixedly connected to the front side of the drying box 1. A filter mechanism 5 and a dehumidification mechanism 9 are provided on the dehumidification box 8.

[0030] Specifically, refer to Figure 1 and Figure 2 The spacing adjustment mechanism 4 includes a drive shaft 47 rotatably connected to the top of the drying chamber 1 and two threaded cylinders 41. The drive shaft 47 is fixedly sleeved with a drive tooth 45, and the two threaded cylinders 41 are fixedly sleeved with driven teeth 43. The drive tooth 45 meshes with the two driven teeth 43. The two threaded cylinders 41 are threadedly sleeved with lifting screws 44. The lower ends of the two lifting screws 44 are fixedly connected to the same mounting bracket 49. Multiple heating tubes 40 are fixedly connected to the front and rear inner walls of the mounting bracket 49.

[0031] The above solution is adopted as follows: According to the different drying requirements of different fabrics, the drive shaft 47 and the active gear 45 are rotated by the handwheel 46. The active gear 45 drives the two driven gears 43 and the threaded cylinder 41 to rotate synchronously. The two threaded cylinders 41 drive the mounting frame 49 and multiple heating tubes 40 to rise and fall, thereby adjusting the distance between the heating tubes 40 and the fabric, so that the heating temperature is appropriate, avoiding burning the fabric if the distance is too close, and reducing the drying efficiency if the distance is too far, requiring a long working time to dry, thus saving energy consumption.

[0032] Specifically, a handwheel 46 is fixedly connected to the top of the drive shaft 47, and two threaded cylinders 41 are rotatably connected to the top of the drying chamber 1 through bearings, which facilitates the rotation of the drive shaft 47 and at the same time supports the threaded cylinders 41 to make their rotation more stable.

[0033] Specifically, the top of the mounting frame 49 is fixedly connected to two guide rods 42. One of the guide rods 42 has a scale line 48 on its outer side. Both guide rods 42 are slidably mounted on the top of the drying box 1, which facilitates the guidance of the mounting frame 49. At the same time, the distance between the heating tube 40 and the fabric can be precisely adjusted through the scale line 48.

[0034] Specifically, refer to Figure 3 and Figure 4 The filtration mechanism 5 includes a mounting block 51 and a filter plate 54 fixedly connected to the bottom of the mounting block 51. The top of the dehumidification box 8 has an installation opening 52. The mounting block 51 is slidably fitted into the installation opening 52. Both sides of the mounting block 51 are fixedly connected with elastic locking blocks 53. The inner walls on both sides of the installation opening 52 have slots. The two elastic locking blocks 53 are respectively movably locked into the corresponding slots.

[0035] The above solution allows for the filtration of the filter plate 54, which removes impurities from the hot air and prevents contamination of the fabric when it is blown back in. The elastic locking block 53 and the locking groove facilitate the fixing of the mounting block 51 and allow the filter plate 54 to be pulled out directly for regular disassembly, cleaning and replacement.

[0036] Specifically, the top of the mounting block 51 is fixedly connected with a handle, which makes it easy to pull the mounting block 51.

[0037] Specifically, refer to Figure 3 and Figure 4The dehumidification mechanism 9 includes a weighing sensor 905 fixedly connected to the inner wall of the bottom of the dehumidification box 8 and a guide rail 912 fixedly connected to one side of the dehumidification box 8. Four support legs 906 are fixedly connected to the top of the weighing sensor 905. A partition 913 is fixedly connected to the top of the four support legs 906. Several water outlet grooves 902 are opened on the top of the partition 913. A water-absorbing sponge 901 is movably placed on the top of the partition 913. The water-absorbing sponge 901 movably abuts against one side of the filter plate 54. A servo motor 909 is fixedly connected to one side of the guide rail 912. A threaded rod 911 is fixedly connected to the output shaft of the servo motor 909. A movable plate 910 is threaded on the outer side of the threaded rod 911. A connecting plate 908 is fixedly connected to one side of the movable plate 910. A sliding rod 904 is fixedly connected to one side of the connecting plate 908. A squeezing mesh plate 903 is fixedly connected to one end of the sliding rod 904. The squeezing mesh plate 903 movably abuts against one side of the water-absorbing sponge 901.

[0038] The above solution involves filtering hot air and blowing it into the absorbent sponge 901, where it absorbs the water vapor, thus achieving dehumidification. This prevents the water vapor from being blown back onto the fabric, which would reduce the drying effect and efficiency. The dehumidified hot air is then blown back into the drying chamber 1 through the return pipe 10, allowing for air recycling and greater energy efficiency. When the absorbent sponge 901 absorbs a significant amount of water over a long period, and the weight measured by the weighing sensor 905 reaches the required level, the weighing sensor 905 sends a signal to the controller. The controller starts the servo motor 909, which drives the rotation of the threaded rod 911. The threaded rod 911 drives the moving plate 910, connecting plate 908, slide rod 904 and extrusion mesh plate 903 to move to the left, squeezing the water-absorbing sponge 901. This causes water to be discharged from the water outlet 902 to below the partition 913, and then discharged from the drain pipe 907. Then the controller starts the servo motor 909 in reverse, which drives the extrusion mesh plate 903 to move to the left and reset. At this time, the water-absorbing sponge 901 is no longer compressed and returns to its original state.

[0039] Specifically, a drain pipe 907 is fixedly connected to one side of the dehumidifier box 8, and a control valve is installed on the drain pipe 907 to facilitate the discharge of water.

[0040] Specifically, the movable plate 910 is slidably sleeved in the guide rail 912, and the partition 913 is slidably sleeved in the dehumidification box 8, which facilitates the guidance of the partition 913 and the movable plate 910, making their movement more stable.

[0041] Working principle: During use, the guide roller 3 facilitates the guidance of the fabric, making its conveying smoother. According to the different drying requirements of different fabrics, the drive shaft 47 and the active gear 45 are rotated by the handwheel 46. The active gear 45 drives the two driven gears 43 and the threaded cylinder 41 to rotate synchronously. The two threaded cylinders 41 drive the lifting and lowering of the mounting frame 49 and multiple heating tubes 40, thereby adjusting the distance between the heating tubes 40 and the fabric to make the heating temperature appropriate. This avoids burning the fabric if the distance is too close, and reducing the drying efficiency if the distance is too far, requiring a long working time to dry the fabric, thus saving energy.

[0042] Hot air is drawn out by the fan 6 and enters the dehumidification chamber 8 through the air outlet pipe 7. After being filtered by the filter plate 54, impurities in the hot air are removed to prevent contamination of the fabric when it is blown back in. The filtered hot air is then blown into the water-absorbing sponge 901, where water vapor is absorbed, thus achieving a dehumidification effect. This prevents water vapor in the hot air from being blown back onto the fabric, which would reduce the drying effect and efficiency. The dehumidified hot air is then blown back into the drying chamber 1 through the return pipe 10, thus recycling the hot air and making it more energy-efficient.

[0043] When the absorbent sponge 901 absorbs a large amount of water after prolonged use, and the weight measured by the weighing sensor 905 reaches the required level, the weighing sensor 905 sends a signal to the controller. The controller then activates the servo motor 909, which drives the rotation of the threaded rod 911. The threaded rod 911 causes the moving plate 910, connecting plate 908, sliding rod 904, and extrusion mesh plate 903 to move to the left, compressing the absorbent sponge 901. This causes the water to drain from the outlet trough 902 to below the partition 913, and then out through the drain pipe 907. The servo motor 909 then reverses and activates again, causing the extrusion mesh plate 903 to move to the left and reset. At this point, the absorbent sponge 901 returns to its original state without pressure. The elastic locking block 53 and the locking groove facilitate the fixing of the mounting block 51 and allow the filter plate 54 to be pulled out directly for periodic disassembly, cleaning, and replacement.

[0044] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

[0045] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
