DETAILED DESCRIPTION

[0029] like Figures 1-9 As shown, a windshield device for a movable dryer conveyor belt includes a conveyor belt body 10, a pair of mirror-symmetrical support frames 11 are provided on the left and right sides of the conveyor belt body 10, and the inner sides of the pair of support frames 11 are fixedly connected to a dryer body 12. The bottom of the dryer body 12 is provided with a pair of mirror-symmetrical position adjustment mechanisms 20, and the position adjustment mechanism 20 includes a movable groove 201 opened on the inner side of the support frame 11, and the interior of the movable groove 201 is slidably connected to a translation box 204 with a matching cross-section, and the interior of the translation box 204 is slidably connected to an L-shaped arm 205 that can move parallel to the left and right, and the L-shaped arm 205 includes a vertical rod and a horizontal rod connected vertically, and the inner side of the horizontal rod is provided with a windshield mechanism 30.

[0030] Preferably, the upper and lower sides of the interior of the movable groove 201 are rotatably connected with a threaded rod 202, and the outer side of the threaded rod 202 is threadedly connected to the translation box 204; the top of the support frame 11 is fixedly connected with a drive motor 203, and the output end of the drive motor 203 is fixedly connected to the top of the threaded rod 202.

[0031] During use, the drive motor 203 is activated by an external power supply. The output end of the drive motor 203 rotates, driving the threaded rod 202 to rotate in the same direction, thereby driving the translation box 204, the L-shaped arm 205, and the windshield mechanism 30 to move up and down, changing the distance between the windshield mechanism 30 and the conveyor belt body 10, thereby achieving the effect of adjusting the height of the windshield mechanism 30. In the drying equipment, raising the windshield mechanism 30 can move the hot air's range upward, which is suitable for drying taller or thicker materials; lowering it allows the hot air to focus on the bottom layer or shorter materials, achieving precise coverage of different types and materials in different positions, thereby improving the drying effect.

[0032] Specifically, the top of the L-shaped arm 205 is respectively provided with a notch 1 207 and a notch 2 208 from front to back; the front and rear sides of the notch 1 207 are rotatably connected to a pinion 209 via a rotating rod, and a moving motor 211 is fixedly installed on the top of the notch 208, and the output end of the moving motor 211 is fixedly connected to the rotating rod; the inner top of the translation box 204 is fixedly connected to a path tooth plate 210, and the pinion 209 is engaged with the path tooth plate 210.

[0033] Preferably, a pair of mirror-symmetrical guide rails 206 are fixedly connected to the front and rear sides of the translation box 204, and the pair of guide rails 206 are respectively slidably connected to the L-shaped arms 205, thereby achieving the effect of guiding and limiting the movement of the L-shaped arms 205.

[0034] When in use, the conveyor belt body 10 is opened, and the material to be dried is placed on the surface of the conveyor belt body 10, and the conveyor belt body 10 transports the material to the other end. During the transportation process, the hot air blown out by the dryer body 12 blows on the surface of the material to dry the material; and in the drying process, since the cross-section of the air outlet of the dryer body 12 is large, the hot air blows on the surface of the object while also blowing on the surface of the conveyor belt where no object is placed. Long-term hot air blowing will damage the conveyor belt, so a wind shield mechanism 30 is proposed; and it is also affected by the width or height of the material. Due to the influence of factors, it is necessary to adjust the spacing or height of a pair of wind shield mechanisms 30; when adjusting the spacing of a pair of wind shield mechanisms 30, the mobile motor 211 is started by an external power supply, and the output end of the mobile motor 211 drives the small gear 209 to rotate, so that the small gear 209 rolls along the surface of the path tooth plate 210, and drives the L-shaped arm 205 and the wind shield mechanism 30 to move; by adjusting the direction of the two mobile motors 211 respectively, the effect of the two L-shaped arms 205 moving toward or away from each other is achieved, and the directions of the two mobile motors 211 are inconsistent.

[0035] refer to Figure 1 、 Figure 4 、 Figure 6 The windshield mechanism 30 includes a rotating rod 301 rotatably connected to the vertical rod in the L-shaped arm 205, and the left and right sides of the rotating rod 301 are respectively rotatably connected to a pair of staggered rotating frames 302, and the interior of the rotating frame 302 is rollingly connected to a rolling rod 306, and the outer side of the rolling rod 306 is rotatably connected to an extension rod 305, and the inner side of the extension rod 305 is slidingly connected to a hollow rod 304, and the inner side of a group of the hollow rods 304 is hinged with a flexible windshield plate 303 through a hinge. The flexible windshield plate 303 is made of fiber material with good elasticity, and the inner side of the flexible windshield plate 303 is fixedly connected to a pullable fixing ring 310.

[0036] Furthermore, the top of the vertical rod of the L-shaped arm 205 is fixedly connected to a cylinder 307, the output end of the cylinder 307 is fixedly connected to a movable gear plate 308, the bottom of the movable gear plate 308 is engaged with a flip gear 309, and the flip gear 309 is fixedly connected to the outer side of the rotating rod 301.

[0037] During use, the cylinder 307 is activated by an external power source. Extending the output end of the cylinder 307 drives the movable toothed plate 308 inward. The movable toothed plate 308 and the flipping gear 309 drive the rotating rod 301 and the flexible windshield 303 upward. Retracting the output end of the cylinder 307 drives the movable toothed plate 308 outward. The movable toothed plate 308 and the flipping gear 309 drive the flexible windshield 303 downward, thereby adjusting the angle of the flexible windshield 303. As the flexible windshield 303 flips, its angle with the conveyor belt and the hot air outlet changes, thereby altering the direction of the hot air flow.

[0038] When the flexible windshield 303 flips upward, the angle between it and the air outlet of the dryer body 12 becomes smaller, and the hot air will be guided to the upper area closer to the conveyor belt, so that the hot air flow rate above the material increases and becomes more concentrated, which can accelerate the evaporation of moisture on the surface of the material. For some materials with high requirements for surface drying speed, this method can quickly remove moisture from the surface of the material and improve drying efficiency; because the hot air is more concentrated near the material, the diffusion to other unrelated areas of the dryer is reduced, thereby reducing the loss of heat to the surrounding environment, improving the utilization rate of heat, and helping to save energy.

[0039] When the flexible wind shield 303 flips downward and the angle with the air outlet of the dryer body 12 becomes larger, the hot air can be blown toward the conveyor belt and the surrounding area at a more inclined angle, thereby expanding the horizontal coverage of the hot air, and allowing the edge parts of the material and the areas on both sides of the conveyor belt to be better affected by the hot air. For materials with a larger width or materials that need to be dried uniformly as a whole, this method is conducive to 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 with a lighter texture, which are easily blown by the wind or are sensitive to wind speed. It can avoid material displacement or damage due to excessive wind speed, and at the same time, it can also make the heat more evenly transferred to the inside of the material, reducing quality problems caused by surface overheating.

[0040] For further reference, Figure 5A transformation mechanism 40 is provided inside the L-shaped arm 205, and the transformation mechanism 40 includes a hollow groove 404 opened inside the vertical rod of the L-shaped arm 205, the rotating rod 301 passes through the hollow groove 404, and the outer side of the rotating rod 301 is fixedly connected to the limiting pulley 405, and the left side of the hollow groove 404 is fixedly connected to a pair of guide pulleys 406 arranged up and down; the front and rear sides of the notch 208 are rotatably connected to a movable rod, and the outer side of the movable rod is rotatably connected to a winding roller 402, and the outer side of the winding roller 402 is fixedly connected to a connecting rope 403, and the connecting rope 403 passes through the inner side of the two guide pulleys 406 and the bottom of the guide pulley 406 in sequence, and is finally fixedly connected to the fixing ring 310.

[0041] Preferably, the movable rod extends forward and passes through the notch 1 207 , and a large gear 401 is fixedly connected to the outer side of the movable rod, and the large gear 401 is meshed with the small gear 209 .

[0042] Initially, the L-shaped arm 205 is located inside the translation box 204 near the side surface of the support frame 11, and the flexible windshield 303 is a convex arc design when it is not deformed (such as Figure 7 When the gear 201 is in the middle of the translation box 204, the flexible windshield 303 is deformed into a flat plate (such as the flat plate 303). Figure 8 ), and 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 windshield 303 to further deform, causing the flexible windshield 303 to deform into a concave arc shape (such as Figure 9 ), and the further the inward movement, the deeper the depression of the flexible windshield 303. Similarly, when the L-shaped arm 205 moves outward, the winding roller 402 gradually unwinds the connecting rope 403, causing the flexible windshield 303 to rebound. The degree of rebound is determined by the amount of unwinding of the connecting rope 403.

[0043] In summary, when the two L-shaped arms 205 are far apart, the two flexible windshields 303 are in the shape of a convex arc, and the distance between the two L-shaped arms 205 is adjusted according to the width of the object. When the width of the object is large, the two convex arc-shaped flexible windshields 303 will cause the hot air to flow along its surface, thereby changing the original flow direction of the hot air. The hot air will be guided upward or downward along the curvature of the curved plate, which can make the hot air better cover the material, especially for some irregularly shaped or thick materials, so that the hot air can contact all parts of the material more evenly. Compared with the existing " / \"-shaped windshield, although it disperses the hot air, the " / \"-shaped windshield has sharp corners and straight lines. When guiding the hot air, it is easy to cause turbulence and eddies at the corners, resulting in uneven distribution of the hot air. During the material drying process, different areas of the material surface may receive different amounts of hot air, affecting the drying quality. Furthermore, the shape of the " / \"-shaped windshield is relatively fixed. Its effectiveness in guiding the hot air may be significantly affected by materials of varying widths or changes in the material's position. For example, when the material width is small, a large amount of hot air may be lost on both sides of the " / \"-shaped windshield, preventing it from fully reaching the material. When the material's position shifts, the hot air may not accurately cover the material.

[0044] When the two L-shaped arms 205 are positioned at a moderate distance from each other and facing a material of moderate width, and the two flexible windshields 303 are shaped like a "\ / ", their opening angles allow the hot air to be directed towards the object of moderate width. Guided by the "\ / " structure, the hot air converges in the area where the object is located, reducing its diffusion and loss, improving its utilization efficiency, and enabling more effective heating or drying of the object.

[0045] When the two L-shaped arms 205 are close to each other, facing materials with a narrow width, the two flexible windshields 303 are in a concave arc shape, and the concave arc plate can 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, so that the hot air can act on the material more accurately, reduce the dispersion and waste of hot air, improve the efficiency of heat utilization, and help to quickly heat or dry narrow materials; above the narrow material, the hot air guided by the concave arc plate will form a relatively uniform thermal field. Under the action of the arc plate, the hot air will form a relatively stable annular airflow around the material, so that all parts of the material can be evenly affected by the hot air, avoiding local overheating or overcooling, which is conducive to ensuring the consistency of material processing and quality stability.

[0046] 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 can focus the hot air into a smaller range, so that objects in a specific area on the conveyor belt can quickly receive a large amount of heat. It is suitable for scenarios where small areas are focused on heating and drying. The “\ / ”-shaped flexible wind shield 303 mainly relies on the angle of the inclined plane to gradually bring the hot air closer, and the convergence is relatively gentle. Due to its planar nature, the hot air converges without the continuous guidance and constraints of an arc, resulting in a less defined focal point. Instead, it focuses on expanding the hot air's coverage area while maintaining relative concentration. This makes it suitable for applications requiring a certain degree of heat concentration but also requiring a relatively large coverage area. Furthermore, in terms of airflow pattern and uniformity, the concave arc-shaped flexible windshield 303 creates a more regular and stable airflow pattern, allowing the hot air to flow along the arc. The airflow is relatively stable in the convergence area, promoting uniform heating of the object. The inclined plane windshield, however, is prone to some disturbance and turbulence during the convergence process due to the plane boundary. While this increases the coverage area, it lacks the uniformity of the curved windshield and performs slightly worse when the object requires high uniformity. Therefore, the two types of flexible windshields 303 are suitable for different materials. The concave arc-shaped flexible windshield 303 is suitable for bulky, accumulated materials that require deep drying, such as granular deposits and thick workpieces, allowing for deep heating. 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.

[0047] Furthermore, not only can the movement of the L-shaped arm 205 adjust the angle of the flexible windshield 303, but the deformation of the flexible windshield 303 can also be changed when the flexible windshield 303 is flipped by the transmission of the movable tooth plate 308 and the flipping gear 309. When the flexible windshield 303 flips upward, because the length of the connecting rope 403 is fixed, the flexible windshield 303 flips upward away from the connection between the connecting rope 403 and the fixed ring 310, causing the flexible windshield 303 to become concave to accommodate the flip. This weakens the curvature of the originally convex flexible windshield 303 and gradually deepens the concave degree of the concave flexible windshield 303. Similarly, when the flexible windshield 303 flips downward, the curvature of the originally convex flexible windshield 303 deepens, and the concave degree of the concave flexible windshield 303 gradually decreases. Since the spacing between the two flexible windshields 303 is adjusted according to the width of the material, after the position is adjusted, if the degree of depression or protrusion of the flexible windshield 303 needs to be further adjusted, the degree of depression or protrusion of the flexible windshield 303 can be increased or decreased by flipping the flexible windshield 303 as described above, or the flexible windshield 303 can be adjusted to a flat shape at different positions to adapt to different types of materials to be dried.

[0048] The working principle of the present invention is as follows: when in use, the conveyor belt body 10 is opened, and the material to be dried is placed on the surface of the conveyor belt body 10, and the conveyor belt body 10 transports the material to the other end. During the transportation process, the hot air blown out by the dryer body 12 blows on the surface of the material to dry the material; and in the drying process, since the cross-section of the air outlet of the dryer body 12 is large, the hot air blows on the surface of the object while also blowing on the surface of the conveyor belt where no object is placed. The hot air blowing for a long time will damage the conveyor belt, so a wind shield mechanism 30 is proposed; and it is affected by factors such as the width or height of the material, and the spacing or height of the pair of wind shield mechanisms 30 needs to be adjusted; when adjusting the spacing of the pair of wind shield mechanisms 30, the mobile motor 211 is started by an external power supply, and the output end of the mobile motor 211 drives the small gear 209 to rotate, so that the small gear 209 rolls along the surface of the path tooth plate 210, and drives the L-shaped arm 205 and the wind shield mechanism 30 to move; by adjusting the direction of the two mobile motors 211 respectively, the effect of the two L-shaped arms 205 moving toward or away from each other is achieved.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
