[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 A drying device for spray painting color-coated steel sheets includes a workbench 1, a conveyor belt 2, and a support 3. The conveyor belt 2 is mounted on the workbench 1, and the support 3 is U-shaped with an open bottom. The two free ends of the support 3 are fixed to the workbench 1, and the conveyor belt 2 is disposed between the two free ends of the support 3. The device also includes:

[0027] The workbench 1 stably supports the conveyor belt 2, which includes a driver, rollers and a carrier belt. It is a conventional structure that can be purchased on the market and is used to transport materials. It will not be described in detail here. The bracket 3 is fixed on the workbench 1 to provide stable support for the drying components.

[0028] The drying assembly includes a lifting assembly, a fan 4, a heating chamber 5, a connecting pipe 6, an air hood 7, and a lifting plate 8. The support 3 is equipped with a lifting assembly that drives the lifting plate 8 to move up and down. The fan 4 and the heating chamber 5 are located on the top wall of the support 3. One end of the fan 4 is connected to the heating chamber 5, and one end of the connecting pipe 6 is connected to the other end of the fan 4. The other end of the connecting pipe 6 passes through the top wall of the support 3 and the lifting plate 8 and connects to the air hood 7. The height of the lifting plate 8 is adjusted by the lifting assembly. The fan 4 and the heating chamber 5 work together. The heating element inside the heating chamber 5 heats the air, and the fan 4 delivers the heated air to the air hood 7 through the connecting pipe 6. During this process, the fan 4 provides power, causing the hot air to circulate continuously, ensuring a continuous and stable heat source in the drying area.

[0029] In actual use, the gap adjustment assembly includes a sealing plate 9 and a guide member. The support 3 and the worktable 1 enclose a working cavity that runs through the front and back. The lifting plate 8 is symmetrically provided with sealing plates 9 on both the front and back sides for adjusting the size of the front and back openings of the working cavity. The sealing plates 9 are connected to the side wall of the support 3 through the guide member. The sealing plates 9 move with the lifting plate 8. As a preferred embodiment, the bottom wall of the sealing plate 9 is lower than the air hood 7. When the air hood 7 is in a suitable position, the sealing plate 9 does not affect the feeding and discharging of materials. At this time, the opening of the working cavity is relatively small to prevent foreign objects from entering from below the support 3 and to protect the surface quality of the color-coated steel plate. When it is necessary to increase the opening, the sealing plate 9 is pushed in the opposite direction, and the opening of the working cavity becomes larger, making it easier to observe the situation inside the cover 10.

[0030] In practical use, it is necessary to ensure the stability of the lifting plate 8's lifting and lowering without affecting the installation of corresponding equipment on the lifting plate 8. Therefore, the lifting assembly includes a cover 10, a motor 11, a worm gear 12, a worm 13, and a screw 14. The cover 10 is mounted on the support 3, and the worm 13 and two sets of worm gears 12 are installed inside the cover 10. The output end of the motor 11 passes through the cover 10 and is connected to the worm 13. A screw 14 is also rotatably mounted between the support 3 and the worktable 1. The top of the screw 14 passes through the support 3 and the cover 10 and is centrally connected to the worm gears 12. The left and right sides of the lifting plate 8 are also provided with screw holes adapted to the screw 14. When the motor 11 in the lifting assembly is started, the motor 11 is a precisely controlled servo motor, and the output end of the motor 11 drives the worm 13 to rotate. The worm 13 meshes with the worm gears 12, thereby driving the worm gears 12 to rotate. Since the worm gear 12 is centrally connected to the screw 14, the rotation of the worm gear 12 drives the screw 14 to rotate. The screw hole on the lifting plate 8 is matched with the screw 14. The rotation of the screw 14 causes the lifting plate 8 to move up and down along the screw 14, thereby adjusting the distance between the air hood 7 and the color-coated steel plate on the conveyor belt 2 to meet the drying requirements of color-coated steel plates of different thicknesses and ensure uniform drying effect.

[0031] In this embodiment, the guide component includes guide posts 15 and guide frames 16. Guide frames 16 are provided on both the left and right sides of the front and rear ends of the bracket 3. The closed plate 9 is also provided with guide posts 15 that are inserted into the guide frames 16. The guide posts 15 are T-shaped. Because the guide posts 15 are T-shaped, the guide frames 16 restrict and guide the movement of the guide posts 15, so that the closed plate 9 can move smoothly towards the middle, reducing the front and rear openings of the working chamber. The sealing strips 17 embedded on the front and rear sides of the top wall of the bracket 3 effectively prevent heat loss from the gaps, improve the energy utilization efficiency of the drying device, and prevent external dust and moisture from entering the drying area, avoiding adverse effects on the drying quality of the color-coated steel sheet.

[0032] In actual use, the sealing plate 9 and the lifting plate 8 are connected by bolts 18. This connection method facilitates disassembly and installation when the sealing plate 9 is damaged, needs cleaning, or requires replacement. Simply unscrewing the bolts 18 allows the sealing plate 9 to be removed from the lifting plate 8, simplifying the operation, reducing equipment maintenance difficulty and costs, and allowing for the replacement of sealing plates of the corresponding specifications to meet the requirements for sealing the working chamber opening.

[0033] The UV lamps 19 embedded on the lower front and rear sides of the lifting plate 8 play an auxiliary drying role in the drying process of the color-coated steel sheet. The ultraviolet rays emitted by the UV lamps 19 can trigger a photochemical reaction in the photosensitive substances in the paint layer on the surface of the color-coated steel sheet, accelerating the curing and drying of the paint layer and improving the drying efficiency. At the same time, the paint layer cured by UV has improved properties such as hardness, wear resistance and adhesion, further improving the coating quality of the color-coated steel sheet. It should be noted that the material feeding speed can be adjusted by the conveyor belt 2 as needed to ensure that the material surface is dried.
