Detailed implementation mode

[0019] As Figures 1-9 Shown in the figure, a wind shielding device for a movable dryer conveyor belt includes a conveyor belt body 10. A pair of mirror-symmetrical support frames 11 are arranged on the left and right sides of the conveyor belt body 10. A dryer body 12 is fixedly connected to the inside of the pair of support frames 11. A pair of position adjustment mechanisms 20 that are mirror-symmetrical left and right are arranged at the bottom of the dryer body 12. The position adjustment mechanism 20 includes a moving groove 201 opened on the inner side of the support frame 11. A translation box 204 with a cross-section adapted to it is slidably connected inside the moving groove 201. An L-shaped arm 205 that can move left and right in parallel is slidably connected inside the translation box 204. The L-shaped arm 205 includes a vertical rod and a horizontal rod that are vertically connected. A wind shielding mechanism 30 is arranged on the inner side of the horizontal rod.

[0020] Preferably, a threaded rod 202 is rotatably connected to the upper and lower sides inside the moving groove 201. The outer side of the threaded rod 202 is threadedly connected to the translation box 204. A drive motor 203 is fixedly connected to the top of the support frame 11. The output end of the drive motor 203 is fixedly connected to the top of the threaded rod 202.

[0021] During use, the drive motor 203 is started through an external power supply. The rotation of the output end of the drive motor 203 drives the threaded rod 202 to rotate in the same direction, thereby driving the translation box 204, the L-shaped arm 205 and the wind shielding mechanism 30 to move up and down, changing the distance between the wind shielding mechanism 30 and the conveyor belt body 10, and thus achieving the effect of adjusting the height of the wind shielding mechanism 30. In a drying device, raising the wind shielding mechanism 30 can move the range of action of the hot air upward, which is suitable for drying higher or thicker stacked materials; lowering it allows the hot air to act concentratedly on the bottom layer or shorter materials, realizing the precise coverage of hot air on different types and different placement states of materials and improving the drying effect.

[0022] Specifically, a first notch 207 and a second notch 208 are respectively formed in the top of the L-shaped arm 205 from front to back; small gears 209 are rotatably connected to the front and rear sides of the first notch 207 through rotating rods, a moving motor 211 is fixedly installed at the top of the second notch 208, and the output end of the moving motor 211 is fixedly connected to the rotating rod; a path toothed plate 210 is fixedly connected to the inner top of the translation box 204, and the small gears 209 are meshed with the path toothed plate 210.

[0023] Preferably, a pair of mirror-symmetrical guide rails 206 are fixedly connected to the front and rear sides inside the translation box 204, and the pair of guide rails 206 are respectively slidably connected to the L-shaped arm 205. Thus, the effect of guiding and limiting the L-shaped arm 205 during movement is achieved.

[0024] During use, the conveyor belt body 10 is started, and the material to be dried is placed on the surface of the conveyor belt body 10. The conveyor belt body 10 conveys the material to the other end. During the conveying process, the hot air blown out by the dryer body 12 blows on the surface of the material to dry the material; during the drying process, since the cross-section of the air outlet of the dryer body 12 is relatively large, when the hot air blows on the surface of the object, it will also blow on the surface of the conveyor belt where no object is placed. The long-term blowing of hot air will damage the conveyor belt. Therefore, the wind shielding mechanism 30 is proposed; also affected by factors such as the width or height of the material, it is necessary to adjust the distance or height between a pair of wind shielding mechanisms 30; when adjusting the distance between a pair of wind shielding mechanisms 30, the moving motor 211 is started through an external power supply, and the output end of the moving motor 211 drives the small gear 209 to rotate, so that the small gear 209 rolls along the surface of the path toothed plate 210 and drives the L-shaped arm 205 and the wind shielding mechanism 30 to move; by respectively adjusting the rotation directions of the two moving motors 211, the effect of the two L-shaped arms 205 moving towards or away from each other is achieved, and the rotation directions of the two moving motors 211 are inconsistent.

[0025] Reference Figure 1 、 Figure 4 、 Figure 6 As shown in

[0026] Further, a cylinder 307 is fixedly connected to the top of the vertical rod of the L-shaped arm 205. The output end of the cylinder 307 is fixedly connected to a moving toothed plate 308. A reversing gear 309 is engaged with the bottom of the moving toothed plate 308. The reversing gear 309 is fixedly connected to the outside of the rotating rod 301.

[0027] During use, the cylinder 307 is started by an external power supply. When the output end of the cylinder 307 extends, it drives the moving toothed plate 308 to move inward. Through the transmission between the moving toothed plate 308 and the reversing gear 309, the rotating rod 301 and the flexible wind shield 303 are driven to turn upward. When the output end of the cylinder 307 contracts, it drives the moving toothed plate 308 to move outward. Through the transmission of the moving toothed plate 308 and the reversing gear 309, the flexible wind shield 303 is turned downward; thus, the effect of adjusting the angle of the flexible wind shield 303 is achieved. When the flexible wind shield 303 turns, the angle between it and the conveyor belt and the hot air outlet changes, thereby changing the flow direction of the hot air.

[0028] When the flexible wind shield 303 turns upward, the angle between it and the air outlet of the dryer body 12 becomes smaller, and the hot air will be guided to a region closer to the upper part of the conveyor belt, increasing the flow rate and concentration of the hot air above the material, which can accelerate the evaporation of the moisture on the surface of the material. For some materials with high requirements for the surface drying speed, this method can quickly remove the moisture on the surface of the material and improve the drying efficiency; since the hot air is more concentrated near the material, the diffusion to other irrelevant areas of the dryer is reduced, thereby reducing the heat dissipation to the surrounding environment and improving the utilization rate of heat, which helps to save energy.

[0029] When the flexible wind shield 303 turns downward and the angle between it and the air outlet of the dryer body 12 becomes larger, the hot air can blow towards the conveyor belt and the surrounding area at a more inclined angle, expanding the coverage range of the hot air in the horizontal direction. The edge part of the material and the areas on both sides of the conveyor belt can be better affected by the hot air. For materials with a large width or materials that need to be dried evenly as a whole, this method is beneficial for achieving comprehensive and uniform drying; compared with when the angle becomes smaller, the wind speed of the hot air on the surface of the material is relatively reduced after the angle becomes larger, which is more beneficial for some materials that are thin and light, easy to be blown by the wind or sensitive to the wind speed. It can avoid the displacement or damage of the material caused by excessive wind speed, and at the same time, it can also make the heat transfer more evenly to the inside of the material, reducing the quality problems caused by overheating on the surface.

[0030] Further, refer to Figure 5, a transformation mechanism 40 is provided inside the L-shaped arm 205. The transformation mechanism 40 includes a hollow groove 404 formed inside the vertical rod of the L-shaped arm 205. The rotating rod 301 penetrates through the hollow groove 404, and a limiting pulley 405 is fixedly connected to the outer side of the rotating rod 301. A pair of guiding pulleys 406 arranged vertically are fixedly connected to the left side of the hollow groove 404. A movable rod is rotatably connected to the front and rear sides of the second notch 208. A winding roller 402 is rotatably connected to the outer side of the movable rod. A connecting rope 403 is fixedly connected to the outer side of the winding roller 402. The connecting rope 403 sequentially passes through the inner sides and the bottoms of the two guiding pulleys 406 and is finally fixedly connected to the fixed ring 310.

[0031] Preferably, the movable rod extends forward through the first notch 207, and a large gear 401 is fixedly connected to the outer side of the movable rod. The large gear 401 meshes with the small gear 209.

[0032] Initially, the L-shaped arm 205 is located on the side surface of the translation box 204 close to the support frame 11. When the flexible wind shield 303 is not deformed, it is designed as a convex arc shape (such as Figure 7 ). During the process of the flexible wind shield 303 moving inward driven by the position adjusting mechanism 20, the small gear 209 rolls along the path tooth plate 210. At the same time, the small gear 209 drives the large gear 401 to rotate the winding roller 402, so that the connecting rope 403 is gradually wound around the surface of the winding roller 402. The gradually shortened connecting rope 403 drives the fixed ring 310 to pull towards the position of the L-shaped arm 205, reducing the bending degree of the flexible wind shield 303. At the same time, the flexible wind shield 303 drives the hollow rod 304 and the extension rod 305 to flip during the deformation process, causing the rolling rod 306 to roll along the inside of the corresponding rotating frame 302, and the rotating frame 302 flips correspondingly on the rotating rod 301 to adapt to the deformation of the flexible wind shield 303. During this process, the extension rod 305 slides along the inside of the hollow rod 304. When the L-shaped arm 205 moves to the middle position inside the translation box 204, the flexible wind shield 303 deforms into a flat plate (such as Figure 8 ). As the L-shaped arm 205 continues to move inward, the winding roller 402 further contracts the connecting rope 403, and the connecting rope 403 pulls the flexible wind shield 303 to further deform, making the flexible wind shield 303 deform into a concave arc shape (such as Figure 9 ), and the farther the inward movement distance is, the deeper the concave degree of the flexible wind shield 303 is. Similarly, when the L-shaped arm 205 moves outward, the winding roller 402 gradually unwinds the connecting rope 403, so that the flexible wind shield 303 rebounds accordingly, and the rebound degree is determined by the amount of unwinding of the connecting rope 403.

[0033] In summary, when the two L-shaped arms 205 are far apart, the two flexible windshields 303 are convex arc-shaped, and the distance between the two L-shaped arms 205 is adjusted according to the width of the object. When the object has a large width, the two convex arc-shaped flexible windshields 303 will cause the hot air to flow along their surfaces, thereby changing the original flow direction of the hot air. The hot air will be guided upward or downward along the curvature of the arc-shaped plate, so that the hot air can better cover the material. Especially for some materials with irregular shapes or certain thicknesses, the hot air can contact all parts of the material more evenly. Compared with the existing " / " shaped windshield, although it disperses the hot air, due to the presence of edges and straight segments in its shape, the " / " shaped windshield is prone to causing turbulence and eddies in the airflow at the edges when guiding the hot air, resulting in uneven distribution of the hot air. During the material drying process, it may cause different amounts of hot air to act on different areas of the material surface, affecting the drying quality. Moreover, the shape of the " / " shaped windshield is relatively fixed, and for materials of different widths or changes in the position of the material, its effect of guiding hot air may be greatly affected. For example, when the material width is small, a large amount of hot air on both sides of the " / " shaped windshield may be lost and cannot fully act on the material; when the position of the material shifts, it is also easy to cause the hot air not to accurately cover the material.

[0034] When the two L-shaped arms 205 are moderately spaced and facing a material of moderate width, and the two flexible windshields 303 are in the shape of "\ / " , the opening angle can cause the hot air to be concentrated and blown towards the object of moderate width. Under the guidance of the "\ / " shaped structure, the hot air will converge in the area where the object is located, reducing the diffusion and loss of the hot air, improving the utilization efficiency of the hot air, and enabling more effective heating or drying and other treatments on the object.

[0035] When the distance between the two L-shaped arms 205 is relatively close and facing a narrow material, the two flexible windshields 303 are in a concave arc shape. The concave arc-shaped plate can concentrate and guide the hot air to the area where the narrow material is located. Due to the concave structure of the arc, the hot air will flow along the inner wall of the arc and converge above the material, making the hot air act more precisely on the material, reducing the dispersion and waste of the hot air, and improving the utilization efficiency of the heat, which helps to quickly heat or dry the narrow material and other treatments; above the narrow material, the hot air guided by the concave arc-shaped plate will form a relatively uniform thermal field. Under the action of the arc-shaped plate, the hot air will form a relatively stable annular air flow around the material, so that all parts of the material can be evenly affected by the hot air, avoiding local overheating or overcooling, and being beneficial to ensuring the consistency and quality stability of the material treatment.

[0036] Although the above-mentioned “\ / ”-shaped flexible wind shield 303 and the concave arc-shaped flexible wind shield 303 can both gather and guide the hot air, the concave flexible wind shield 303 uses the arc-shaped surface to guide the hot air, which is a convergence method based on a curve trajectory. The hot air flows and converges along the continuously changing curved surface. The convergence effect is more concentrated and precise, and the hot air can be focused on a smaller range, so that objects in a specific area on the conveyor belt can quickly receive a large amount of heat, which is suitable for the scene of focused heating and drying in a small area; while the “\ / ”-shaped flexible wind shield 303 mainly relies on the angle of the inclined plane to gradually bring the hot air together, and the convergence is relatively gentle. Due to the plane characteristics, the hot air convergence process lacks continuous guiding constraints like the arc, and the convergence focus is not so clear. It is more about making the hot air relatively concentrated on the basis of expanding the hot air coverage, which is suitable for situations where a certain degree of heat concentration is required but a relatively large coverage area is required; and in terms of airflow form and uniformity, the concave arc flexible windshield 303: can shape a more regular and stable airflow form, the hot air flows along the arc, and the airflow is relatively stable in the convergence area, which is conducive to uniform heating of the object. Inclined plane windshield: Due to the existence of the plane boundary, the airflow is prone to certain disturbances and turbulence during the convergence process. Although it can increase the coverage area, it is different from the arc windshield in uniformity, and the performance is slightly inferior when the object has high requirements for uniform heating. Therefore, the flexible windshield 303 in the above two states is also applicable to different materials. The concave arc flexible windshield 303: is suitable for block-shaped, stacked materials that need to be deeply dried, such as granular deposits, thick block workpieces, etc., and can heat the interior deeply. Inclined plane flexible windshield 303: more suitable for flat materials with requirements on coverage area, such as thin sheets, large-area plates, etc., and can take into account both heating and overall coverage.

[0037] Moreover, not only can the moving position of the L-shaped arm 205 adjust the angle of the flexible windshields 303, but also when the flexible windshields 303 are flipped by the transmission of the moving toothed plate 308 and the flipping gear 309, the deformation of the flexible windshields 303 can also be driven to change. When the flexible windshields 303 are flipped upward, since the length of the connecting rope 403 is fixed, and the upward flipping of the flexible windshields 303 will move away from the connection between the connecting rope 403 and the fixing ring 310, the flexible windshields 303 will be concave to adapt to the flipping; the arc degree of the originally convex flexible windshields 303 will be weakened, and the concave degree of the concave flexible windshields 303 will be gradually deepened; similarly, when the flexible windshields 303 are flipped downward, the arc degree of the originally convex flexible windshields 303 will be deepened, and the concave degree of the concave flexible windshields 303 will be gradually reduced. Since the distance between the two flexible windshields 303 is adjusted according to the width of the material, after the position is adjusted, if the concave or convex degree of the flexible windshields 303 needs to be further adjusted, the concave or convex degree of the flexible windshields 303 can be increased or weakened according to the above method of flipping the flexible windshields 303, or the flexible windshields 303 can be adjusted to a flat shape at different positions. To adapt to different types of materials to be dried.

[0038] The working principle of the present invention is as follows: When in use, the conveyor belt body 10 is started, and the material to be dried is placed on the surface of the conveyor belt body 10. The conveyor belt body 10 conveys the material to the other end. During the conveying process, the hot air blown by the dryer body 12 blows on the surface of the material to dry the material; during the drying process, since the cross-sectional area of the air outlet of the dryer body 12 is relatively large, when the hot air blows on the surface of the object, it will also blow on the surface of the conveyor belt where no object is placed. The long-term blowing of hot air will damage the conveyor belt. Therefore, the windshield mechanism 30 is proposed; also affected by factors such as the width or height of the material, it is necessary to adjust the distance or height between a pair of windshield mechanisms 30; when adjusting the distance between a pair of windshield mechanisms 30, the moving motor 211 is started through an external power supply. The output end of the moving motor 211 drives the small gear 209 to rotate, so that the small gear 209 rolls along the surface of the path toothed plate 210, and drives the L-shaped arm 205 and the windshield mechanism 30 to move; by respectively adjusting the rotation directions of the two moving motors 211, the effect of the two L-shaped arms 205 moving towards or away from each other is achieved.
