[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1-8 The utility model provides a technical solution: a drying device with uniform air blowing, comprising a drying box 1, a conveying frame 2 is horizontally provided inside the drying box 1, and openings 3 are symmetrically opened on both sides of the outer wall of the drying box 1, and hot air conveying components are symmetrically provided on both sides of the top of the drying box 1, and the hot air conveying components extend to the top of the inner wall of the drying box 1. The inner wall of the drying box 1 is horizontally provided with a plurality of second support rods 7 and a first support rod 6 rotatably connected thereto above the conveying frame 2, the outer wall of the first support rod 6 is provided with spiral blades 8, and the top of the second support rod 7 is provided with a plurality of rotatably connected wind dispersion components 9; air inlets 4 are symmetrically opened on both sides of the top of the drying box 1, and the hot air conveying component includes a fan 10, an air supply duct 11 and an electric heating wire 5, the electric heating wire 5 is arranged on the top of the inner wall of the drying box 1, and the electric heating wire 5 is arranged below the air inlet 4, and the fan 10 is connected to the air inlet 4 through the air supply duct 11; a servo motor 12 is provided on the outer wall of the drying box 1, and the output end of the servo motor 12 is fixedly connected to one end of the first support rod 6.

[0029] The distance between two adjacent second support rods 7 is greater than the outer diameter of the air dispersion component 9, and the distance between two adjacent second support rods 7 is less than twice the outer diameter of the air dispersion component 9, which can effectively prevent the air dispersion components 9 from colliding or wearing each other during rotational motion, and at the same time effectively ensure that the air dispersion component 9 covers the hot air delivered by the hot air delivery component, thereby ensuring uniform dispersion and guidance of the hot air.

[0030] The air dispersion component 9 can be one or more of a turbine blade, a conical guide plate, and an impeller. The air dispersion component 9 is designed to be in the shape of a turbine blade, a conical guide plate, and an impeller, so that when the hot air blows to the top of the air dispersion component 9, the hot air drives the air dispersion component 9 to rotate. At the same time, the hot air is diffused and guided along the lines and channels on the surface of the air dispersion component 9, which can effectively ensure the air dispersion treatment effect of the hot air, thereby improving the uniformity of the hot air distribution inside the drying box 1.

[0031] The spiral directions of the spiral blades 8 provided at both ends of the outer wall of the first support rod 6 are opposite, so that the conveying directions of the two hot air conveying assemblies corresponding to the spiral blades 8 at both ends of the outer wall of the first support rod 6 are different, which can further ensure the uniform distribution of hot air inside the drying box 1.

[0032] In one embodiment, the second support rod 7 is arranged below the first support rod 6, so that the air dispersion component 9 is located above the spiral blade 8. After the hot air is transported to the inside of the drying box 1 through the hot air delivery component, it is first diffused by the horizontal rotation movement of the air dispersion component 9, and then passes through the spiral blade 8 for spiral guidance and diffusion treatment in the vertical direction.

[0033] In one embodiment, the second support rod 7 is arranged above the first support rod 6, so that the air dispersion component 9 is located below the spiral blade 8. After the hot air is transported to the inside of the drying box 1 through the hot air delivery component, it first passes through the spiral blade 8 for spiral guidance and diffusion treatment in the vertical direction, and then passes through the air dispersion component 9 for rotational movement and diffusion treatment in the horizontal direction.

[0034] The working principle of this utility model:

[0035] Refer to the instruction manual Figures 1-8 The utility model is provided with a hot air conveying component, a first support rod 6, a second support rod 7, a spiral blade 8 and an air dispersing component 9. The hot air conveying component conveys hot air to the inside of the drying box 1. After entering the drying box 1, the hot air first passes through the first support rod 6 and the second support rod 7, and then blows to the top of the conveying rack 2. The leather to be dried is placed on the surface of the conveying rack 2 through the opening 3 on one side of the drying box 1. The conveying rack 2 rotates to drive the belt to pass through the drying box 1 and is sent out from the opening 3 on the other side of the drying box 1. When the hot air blows to the surface of the first support rod 6, the spiral blade 8 guides the hot air, and the hot air moves downward along the surface shape of the spiral blade 8. The spiral blade 8 can effectively The spiral guided diffusion treatment can effectively improve the diffusion treatment of the hot air inside the drying box 1, thereby improving the uniformity of the hot air inside the drying box 1; when the hot air blows to the surface of the second support rod 7, the hot air blows to the surface of the air dispersion component 9 on the top of the second support rod 7, and the air dispersion component 9 rotates to perform a rotational dispersion treatment on the hot air, and the hot air radiates outward along the air dispersion component 9, which can effectively improve the uniformity of the distribution of the hot air inside the drying box 1. The coordinated use of the spiral blades 8 and the air dispersion component 9 can further improve the uniformity of the hot air dispersion inside the drying box 1, making the hot air blown to the leather more uniform, which can effectively improve the uniformity of the heating of the leather during the drying process, and can effectively avoid local damage to the leather due to heat;

[0036] When the hot air inlet assembly is working, the fan 10 is started, and the fan 10 conveys the ambient air to the air inlet 4 through the air supply duct 11. After the ambient air passes through the air inlet 4, it needs to pass through the electric heating wire 5 before entering the drying box 1, which can effectively ensure that the hot air is continuously conveyed to the drying box 1.

[0037] The servo motor 12 drives the first support rod 6 to rotate. The first support rod 6 rotates actively, and the spiral blade 8 rotates along with the first support rod 6, so that when the hot air blows through the spiral blade 8 on the surface of the first support rod 6, the hot air moves downward along the surface shape of the spiral blade 8. The spiral blade 8 can effectively perform spiral guidance and diffusion treatment on the hot air. After the spiral blade 8 actively rotates, the contact guide surface shape of the spiral blade 8 and the hot air is continuously switched, so that the movement direction of the hot air after being guided by the spiral blade 8 is continuously switched, which can further improve the uniformity of the distribution of the hot air inside the drying box 1, thereby effectively improving the uniformity of heating of the leather during the drying process, and effectively avoiding local heat damage to the leather.
