Description
Technical Field
[0001] The utility model belongs to the technical field of sheet metal drying equipment processing, in particular to a drying equipment for spraying. Background Art
[0002] In existing technology, sheet metal parts require drying after spraying to ensure the coating is effective. The primary purpose of drying sheet metal parts is to remove moisture from the workpiece surface, thereby improving its quality and performance. Drying can reduce problems such as rust and deformation during subsequent processing or use. There are various methods for drying sheet metal parts, including industrial dryers, vibrating dryers, and tunnel ovens.
[0003] China's authorization announcement number is "CN221816519 U", and the announcement date is 2024.10.11, which discloses a spraying device for sheet metal production, including a processing box, an adjustment component, a spraying mechanism and a drying mechanism. The processing box is equipped with a box door, and a collection drawer is installed at the lower end of the inner cavity of the processing box. The adjustment component is installed at the upper end of the inner cavity of the processing box, and the adjustment component is connected to a clamping mechanism; the adjustment component includes a first servo electric cylinder and a servo motor, the first servo electric cylinder is fixedly installed at the upper end of the inner cavity of the processing box, and the output end of the first servo electric cylinder is fixedly connected to the servo motor. The spraying mechanism is installed on one side of the processing box, and the drying mechanism is installed on the processing box away from the sprayer.
[0004] One side of the structure; the utility model can drive the sheet metal to adjust the height and angle through the setting of the adjustment component, so as to perform multi-angle adjustment spraying on the sheet metal, which can more effectively cover sheet metal parts with complex shapes or irregular surfaces, thereby improving the coating efficiency.
[0005] The above structure sets the drying mechanism on the other side of the box body, and then realizes drying by fixing the air outlet on the box body. It is necessary to adjust the components to hang the objects to be dried to the corresponding height before drying. Since the box body is closed during the drying process, it is impossible to reliably determine whether the drying mechanism can be ready to bake the objects to be dried. Moreover, for small sheet metal parts, if the drying mechanism is always open, the air will be discharged before the objects to be dried reach the destination, thereby wasting energy. Utility Model Content
[0006] The purpose of the utility model is to provide a drying device for spraying, which can reliably bake a baking device when a workpiece is placed therein, thereby reducing energy consumption.
[0007] To achieve the above objectives, the present invention provides the following technical solutions:
[0008] The top of the drying box is provided with a drying box, and the drying box is provided with more than two insertion slots at intervals along the length direction of the drying box, and a pulling box is slidably provided on the insertion slots.

Then, since the sheet metal parts are placed in the pulling box, the pressure plate tilts under the action of gravity of the pulling box, so that the sealing plate rotates around the rotating shaft, so that the sealing plate opens the air outlet, and the hot air from the hot air pipe comes out from the air outlet and then enters the pulling box through the air vent for baking. Therefore, the sealing plate can be opened for baking only when the sheet metal parts are installed, which can improve the utilization rate of energy, and the air can be discharged to the pulling box through the hot air pipe for baking, which can further ensure the baking effect.
[0010] Furthermore, there are more than two rotating shafts, and more than two rotating sleeves are provided on the pressure plate. One side end of one rotating shaft is fixedly connected to a spring plate, and one side end of the rotating sleeve and one side end of the spring plate are fixedly connected to a torque spring.
[0011] The above arrangement, through the arrangement of the torque spring, can reliably reset the pulling box when it is pulled out of the insertion slot so as to cover the air outlet.
[0012] Furthermore, the lower end of the pulling box is fixedly connected to a containing box, more than two layers are fixedly connected inside the containing box, and a ventilation hole is opened on one side end of the containing box.
[0013] The above arrangement can facilitate the entry of hot air through the vent holes on each layer of the containing box for drying.
[0014] Furthermore, a heat source connection slot receiving opening is provided at one side end of the drying box body, and a blocking block is fixedly connected to a position corresponding to the insertion slot in the pulling box.
[0015] The above arrangement connects the heat source connection slot to an external heat source through the heat source receiving port, thereby realizing the input of the heat source. In addition, a closed space can be formed between the pulling box and the insertion slot by arranging a blocking block.
[0016] Furthermore, a handle is fixedly connected to the upper end of the pulling box, and a cotton pad is fixedly connected to the outer surface of the handle.
[0017] The above arrangement can facilitate the putting in and pulling out of the suitcase.
[0018] Furthermore, one side end of the drying box is provided with more than two groups of air outlet components, and the air outlet components each include a hot air outlet, a connecting plate and an air outlet plate. The hot air outlet is opened at one side end of the drying box, the connecting plate is fixedly connected to one side end of the drying box, and the air outlet plate is fixedly connected to the connecting plate.
[0019] The above arrangement can facilitate the replacement of the air outlet plate by connecting the air outlet plate to the connecting plate.

[0031] See also Figure 1-Figure 5 The present invention provides the following technical solutions: a spray drying device, comprising: a drying box 1; two or more insertion slots 2 are provided on the drying box 1 along the length direction of the drying box 1, and a pull box 3 is provided on the insertion slot 2 to match and slide. In this embodiment, there are three pull boxes 3, and the three pull boxes 3 are respectively slidably connected to the three insertion slots 2;
[0032] The drying components include a hot air pipe 4, a vertical plate 5, a rotating shaft 6, a rotating sleeve 7, a pressing plate 8, an air outlet 9 and a sealing plate 10. There are multiple vertical plates 5, rotating shafts 6, air outlets 9 and sealing plates 10. The hot air pipe 4 is fixedly connected to the drying box body 1, and multiple vertical plates 5 are fixedly connected to the lower inner wall of the drying box body 1. Multiple rotating shafts 6 are respectively fixedly connected to the upper ends of multiple vertical plates 5. The rotating sleeve 7 is rotatably connected to the circumferential surfaces of multiple rotating shafts 6. The pressing plate 8 is fixedly connected to one side end of the rotating sleeve 7. Multiple air outlets 9 are opened at one side end of the hot air pipe 4. Multiple sealing plates 10 are fixedly connected to one side end of the pressing plate 8 and rotatably connected to the multiple air outlets 9.
[0033] In this embodiment, the hot air pipe 4 is a frame structure, and an inclined surface is provided on the upper end of the hot air pipe near the side of the pulling box. The inclined surface is inclined outward and upward, and an air outlet is provided on the inclined surface and the vertical surface near the side of the pulling box. The air outlet is inclined outward and upward, so that the gas can enter the pulling box over a larger range. In order to further increase the ventilation, an exhaust fan can be provided on the top of the pulling box so that the wind from the air outlet can better enter the pulling box.
[0034] like Figure 5 As shown, the blocking plate 10 includes a first blocking plate 101, a second blocking plate 102, and a third blocking plate 103. One end of the first blocking plate 101 is fixedly connected to the pressure plate 8, and the other end of the first blocking plate 101 is obliquely connected to one end of the second blocking plate. One end of the second blocking plate 102 is fixedly connected to one end of the third blocking plate 103, and the other end of the third blocking plate 103 is free. An acute angle is formed between the first blocking plate 101 and the second blocking plate 102, while an obtuse angle is formed between the second blocking plate 102 and the third blocking plate 103. This allows for more effective blocking of the inclined air outlet.
[0035] In a specific embodiment of the present invention, a drying box 1 is used to dry workpieces for spraying equipment. The drying equipment is arranged at the bottom of the drying box 1. The pulling box 3 is used to load and dry sheet metal parts. The hot air pipe 4 is connected to an external drying heat source. By burning natural gas, hot air is generated, and then input into the hot air pipe 4 to dry the workpiece. There are multiple air outlets 9 on the hot air pipe 4 to input hot air into the drying box 1. The openings of the multiple air outlets 9 are blocked by a blocking plate 10. When drying the workpiece, the workpiece is placed in the pulling box 3, and then the pulling box 3 is inserted into the drying box 1 through the insertion slot 2, and the upper opening of the insertion slot 2 is blocked at the same time. When the pulling box 3 is full of sprayed workpieces, the overall weight of the pulling box 3 is higher, and the pulling box 3 is pressed on the inclined On the pressing plate 8, press the pressing plate 8 downward and parallelize it. While the pressing plate 8 rotates around the rotating shaft 6, the sealing plate 10 on the other side of the pressing plate 8 also rotates downward, thereby opening the air outlet 9. At this time, the air outlet 9 corresponding to the position where the pulling box 3 for holding the workpiece is placed is opened, and the openings of multiple air outlets 9 are tilted upward. At this time, the hot air released by the opened air outlet 9 dries the workpiece in the pulling box 3 at the corresponding position. When the pulling box 3 is empty and no workpiece is placed, the weight of the pulling box 3 cannot press the pressing plate 8 downward. At this time, the sealing plate 10 blocks the air outlet 9 to avoid wasting hot air, so that when the device dries the workpiece, it only releases hot air to dry the position where the workpiece is placed, reducing the natural gas required for drying the workpiece and saving drying costs.
[0036] For details, please refer to Figure 1-Figure 5 One side end of the rotating shaft 6 is fixedly connected to a spring plate 11 , and one side end of the rotating sleeve 7 and one side end of the spring plate 11 are fixedly connected to a torque spring 12 .
[0037] In this embodiment: one side end of the torque spring 12 is fixed by the spring plate 11, and the other end pulls the rotating sleeve 7 and rotates with the rotating sleeve 7. When a workpiece is placed on the pulling box 3, the mass of the pulling box 3 is sufficient to torque the torque spring 12 to rotate the rotating sleeve 7. When the pulling box 3 is empty, the mass of the pulling box 3 is insufficient to torque the torque spring 12, so that the sealing plate 10 blocks the air outlet 9 to avoid waste of hot air.
[0038] For details, please refer to Figure 1-Figure 5 The lower end of the pulling box 3 is fixedly connected to the containing box 13, and the containing box 13 is fixedly connected with a multi-layer containing plate 22. A ventilation hole 14 is opened at one side end of the containing box 13.
[0039] In this embodiment, the holding plate 22 is a hollow plate for placing workpieces for drying. The air vents 14 are provided on both sides of the holding box 13. The hot air ejected from the air outlet 9 can enter the holding box 13 through the air vents 14 and dry the workpieces in the holding box 13.
[0040] For details, please refer to Figure 1-Figure 5 A heat source connection slot containing plate 21 is provided at one side end of the drying box body 1 , and a blocking block 15 is fixedly connected to the pulling box 3 .
[0041] In this embodiment: the heat source connecting groove holding plate 21 is an opening for connecting hot air, and the hot air pipe 4 is connected to the external heating equipment from the torque spring 12. The blocking block 15 is arranged at the upper end of the holding box 13. When there is no workpiece in the pulling box 3, the pressing plate 8 presses against the pulling box 3 so that the upper end of the pulling box 3 protrudes a certain height from the upper end of the insertion groove 2. At this time, the blocking block 15 blocks the upper opening of the insertion groove 2 to prevent hot air from leaking from the insertion groove 2. In this embodiment, the blocking block 15 can be a sealing block. Sealing blocks are respectively provided on the four sides of the pulling box 3 to achieve sealing. The height of the four sides of the pulling box 3 is greater than or equal to the distance that the pressing plate 3 moves downward. When the pressing plate 8 can be rotated, the sealing blocks on the four sides of the pulling box 3 are completely fitted with the four sides of the insertion groove 2.
[0042] For details, please refer to Figure 1-Figure 5 The upper end of the pulling box 3 is fixedly connected with a handle 16 , and the outer surface of the handle 16 is fixedly connected with a cotton pad 17 .
[0043] In this embodiment, the handle 16 is provided at the upper end of the drying box 1 , and the cotton pad 17 is made of cotton material. When the workpiece is dried, the operator holds the cotton pad 17 to pull up the lifting box 3 and take the workpiece out of the drying box 1 .
[0044] For details, please refer to Figure 1-Figure 5 One side end of the drying box body 1 is provided with multiple groups of air outlet components, each group of air outlet components includes a hot air outlet 18, a connecting plate 19 and an air outlet plate 20, the hot air outlet 18 is opened at one side end of the drying box body 1, the connecting plate 19 is fixedly connected to one side end of the drying box body 1, and the air outlet plate 20 is fixedly connected to the connecting plate 19.
[0045] In this embodiment, threaded holes are provided on one side of the connecting plate 19 and the air outlet plate 20 , and the air outlet plate 20 is fixed to one side of the hot air outlet 18 through the threaded holes. The hot air in the drying box 1 dries the workpiece from bottom to top and is released from the air outlet plate 20 .
[0046] The working principle and usage process of the present invention are as follows: the drying box 1 is used for drying the workpieces for the spraying equipment. The drying equipment is arranged at the bottom of the drying box 1. The pulling box 3 is used for loading the dried workpieces. The hot air pipe 4 is connected to the external drying heat source. By burning natural gas, hot air is generated, and then input into the hot air pipe 4 to dry the workpieces. There are multiple air outlets 9 on the hot air pipe 4 to input hot air into the drying box 1. The openings of the multiple air outlets 9 are blocked by the blocking plate 10. When drying the workpiece, the workpiece is placed in the pulling box 3, and then the pulling box 3 is inserted into the drying box 1 through the insertion slot 2, and the upper opening of the insertion slot 2 is blocked at the same time. When the pulling box 3 is full of sprayed workpieces, the overall weight of the pulling box 3 is higher, and the pulling box 3 is pressed on the tilting plate. On the inclined pressing plate 8, the pressing plate 8 is pressed down and parallel. While the pressing plate 8 rotates with the rotating shaft 6 as the axis, the sealing plate 10 on the other side of the pressing plate 8 also rotates upward, thereby opening the air outlet 9. At this time, the air outlet 9 corresponding to the position where the pulling box 3 for holding the workpiece is placed is opened, and the openings of multiple air outlets 9 are inclined upward. At this time, the hot air released from the opened air outlet 9 dries the workpiece in the pulling box 3 at the corresponding position. When the pulling box 3 is empty and no workpiece is placed, the weight of the pulling box 3 cannot press the pressing plate 8 down. At this time, the sealing plate 10 blocks the air outlet 9 to avoid waste of hot air, so that when the device dries the workpiece, it only releases hot air to dry the position where the workpiece is placed, reducing the natural gas required for drying the workpiece and saving drying costs.
[0047] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
