Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and more specifically, to a surface treatment device for coated parts with high-efficiency anti-corrosion function. Background Technology

[0002] Highly efficient anti-corrosion surface treatment equipment for coated parts mainly includes sandblasting machines, spraying equipment, surface cleaning equipment, and drying and curing equipment. These devices play a crucial role in anti-corrosion surface treatment and coating application, ensuring the quality and efficiency of the work. The curing equipment enables the anti-corrosion coating on the workpiece surface to form a dense chemical structure, which can resist corrosion from various chemicals during chemical production processes, extending the service life of the equipment.

[0003] There are many existing technologies for curing devices, such as:

[0004] Chinese patent application CN221674833U discloses a coating drying and curing device, comprising a base, a coating table, and a drying assembly. A fixing block is fixedly connected to one side of the base, and a coating chamber shell is fixedly connected to the upper end of the fixing block. A drying assembly is disposed on one side of the coating chamber shell, with a first air vent on one side of the drying assembly, a metal mesh on one side of the first air vent, a fan on one side of the metal mesh, a heating element on one side of the fan, and a second air vent on one side of the heating element. With this device, when it is necessary to dry the coated item, the controller controls the fan and heating element to operate, causing the first air vent to draw in outside air, which is then filtered through the metal mesh to remove impurities, heated to the required temperature by the heating element, and finally delivered into the coating chamber shell through the second air vent to dry and cure the coated item. This achieves rapid drying and curing of the coated item, improving coating efficiency and quality.

[0005] Existing curing devices use fans to blow hot air onto the surface of the coated parts. However, the direction of the hot air is relatively fixed, making it difficult to reach other surfaces of the workpiece. This can lead to uneven drying and surface defects such as orange peel, runs, and pinholes in the coating. Corrosive media can penetrate into the coating through these weak points and come into contact with the coated object, affecting the coating's anti-corrosion performance. Therefore, we propose a surface treatment device for coated parts with high-efficiency anti-corrosion function. Utility Model Content

[0010] As a further improvement to this technical solution, the drying oven is provided with a transmission assembly, which includes a rotating rod rotatably mounted on one side of the top of the drying oven. The lower part of the transmission assembly rotatably extends into the inner cavity of the drying oven. A transmission pulley is fixedly mounted on the upper end of the rotating shaft, and a driven pulley is fixedly mounted above the rotating rod. An annular belt is provided between the surfaces of the transmission pulley and the driven pulley. A transmission bevel gear is fixedly mounted on the lower end of the rotating rod, and the transmission bevel gear is located in the inner cavity of the drying oven.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this highly efficient anti-corrosion surface treatment device for coated parts, during the drying process, a motor is started to drive a rotating shaft, which in turn drives the fan blades at the bottom to rotate. The heat generated by the heating grid is blown out through the air collector hood, allowing the hot air to be directed more concentratedly to the surface of the coated part, accelerating the evaporation of solvents in the coating. As the rotating shaft rotates, the transmission assembly drives the guide plate to rotate, guiding the airflow so that the hot air is blown onto different surfaces of the workpiece, achieving uniform drying and curing. Uniform drying and curing can prevent surface defects such as orange peel, runs, and pinholes from appearing on the coating, preventing corrosive media from penetrating into the coating through these weak points and then contacting the coated object, thus affecting the anti-corrosion performance of the coating. This is beneficial for further improving the corrosion resistance of the workpiece and enhancing its overall aesthetics. Attached Figure Description

[0031] 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.

[0032] Please see Figures 1-7 As shown, this embodiment provides a surface treatment device for coated parts with high-efficiency anti-corrosion function, including a base 1, a conveying component 2 is provided on the top of the base 1, and a drying box 3 is fixedly provided on the top of the conveying component 2; a drying component 4 is provided on the top of the inner wall of the drying box 3; a flow guiding component 5 is provided on the top of the inner cavity of the drying box 3, the flow guiding component 5 is located directly below the drying component 4, and a transmission component 6 is provided between the flow guiding component 5 and the drying component 4.

[0033] The top of the inner wall of the drying chamber 3 is provided with a receiving slot for installing the drying component 4. The drying component 4 is used to blow hot air to dry the coated workpiece. When the drying component 4 is running, the transmission component 6 drives the guide component 5 to rotate, adjusting the air direction and angle.

[0034] The improvement in this embodiment is that when drying the coated part, the drying component 4 is activated to blow hot air onto the surface of the coated part. While the drying component 4 is running, the transmission component 6 drives the guide component 5 to rotate, adjusting the air direction so that the hot air is blown onto different surfaces of the workpiece, achieving uniform drying and curing. Uniform drying and curing can avoid surface defects such as orange peel, runs, and pinholes in the coating, preventing corrosive media from penetrating into the coating through these weak points and then contacting the coated object, affecting the anti-corrosion performance of the coating. This is beneficial to further improve the corrosion resistance of the workpiece and enhance the overall aesthetics of the workpiece. Moreover, after passing through the guide component 5, the hot air becomes more concentrated on the surface of the workpiece, accelerating the diffusion of solvent or water molecules from the surface of the coated part into the air, which is beneficial to quickly dry and cure the surface of the coated part.

[0035] To facilitate the drying of painted parts, therefore, as Figures 3-7 As shown, the drying assembly 4 includes a rotating shaft 41 rotatably disposed in a receiving groove above the inner cavity of the drying chamber 3. The upper end of the rotating shaft 41 rotatably extends out of the receiving groove of the inner cavity of the drying chamber 3, and the extended end is fixedly connected to the output end of the motor. Multiple fan blades 42 are provided at the bottom of the rotating shaft 41. A heating grid 43 is fixedly provided at the bottom of the receiving groove in the inner cavity of the drying chamber 3. The heating grid 43 is located directly below the fan blades 42. When drying the coated parts, the door of the drying chamber 3 is opened, and the conveying assembly 2 conveys the coated parts into the inner cavity of the drying chamber 3. Then, the heating grid 43 is started to heat up, and at the same time, the motor is started to drive the rotating shaft 41 to rotate. The rotating shaft 41 drives the fan blades 42 at the bottom to rotate, blowing the heat generated by the heating grid 43 to the surface of the workpiece and the surrounding environment, accelerating the diffusion of solvent or water molecules from the surface of the coated parts into the air, so that the surface of the coated parts dries and cures. The cured coating forms a continuous and dense protective film on the surface of the coated parts, which can effectively prevent external corrosive media from contacting the surface of the coated workpiece, inhibit the rusting process of the workpiece, and improve the corrosion resistance of the workpiece.

[0036] Considering that the hot air blown out by the fan blade 42 tends to concentrate in a certain direction, therefore, as Figures 3-6 As shown, the air guiding assembly 5 includes an air collecting hood 51 fixedly installed at the top of the inner cavity of the drying oven 3. The air collecting hood 51 is located directly below the heating grid 43. A guide plate 52 is rotatably installed below the inner cavity of the air collecting hood 51. The side length of the guide plate 52 is smaller than the inner diameter of the air collecting hood 51. When the fan blade 42 rotates and blows air, the guide plate 52 inside the air collecting hood 51 rotates. The air collecting hood 51 can guide the hot air blown out by the fan blade 42 to the surface of the coated part more concentratedly, so that the solvent in the coating evaporates faster. During the rotation, the guide plate 52 can change the flow direction of the hot air and guide the hot air to different surfaces of the coated part, which is conducive to achieving uniform drying. Uniform air drying and curing can avoid surface defects such as orange peel, sagging, and pinholes in the coating, and prevent corrosive media from penetrating into the interior of the coating through these weak points and then contacting the coated object, affecting the anti-corrosion performance of the coating. This is conducive to further improving the corrosion resistance of the workpiece and improving the overall aesthetics of the workpiece.

[0037] To facilitate the swinging of the guide vane 52, therefore, as Figures 1-5As shown, a transmission assembly 6 is provided on the drying chamber 3. The transmission assembly 6 includes a rotating rod 61 rotatably mounted on one side of the top of the drying chamber 3. The lower part of the transmission assembly 6 rotatably extends into the inner cavity of the drying chamber 3. A transmission pulley 62 is fixedly mounted on the upper end of the rotating shaft 41, and a driven pulley 63 is fixedly mounted above the rotating rod 61. An annular belt 64 is provided between the surfaces of the transmission pulley 62 and the driven pulley 63. A transmission bevel gear 65 is fixedly mounted on the lower end of the rotating rod 61, and the transmission bevel gear 65 is located in the inner cavity of the drying chamber 3. A driven bevel gear 66 is meshed with the outer edge of the transmission bevel gear 65. Shafts for rotatably connecting with the air collector hood 51 are fixedly mounted on both sides of the guide plate 52, and one side of the shaft rotatably extends out of the inner cavity of the air collector hood 51. The driven bevel gear 66 is fixedly mounted on the surface of the shaft extending out of the guide plate 52. When the coated parts are dried and cured, the motor is started to drive the rotating shaft 41 to rotate. The rotating shaft 41 drives the bottom fan blade 42 to rotate, which in turn drives the transmission pulley 62 on the upper surface to rotate. Then, the surface of the transmission pulley 62 and the belt 64 in contact with each other generate friction, thereby driving the belt 64 to rotate. Similarly, the belt 64 drives the driven pulley 63 to rotate. The driven pulley 63 drives the rotating rod 61 fixedly connected to it to rotate. When the rotating rod 61 rotates, it drives the bottom transmission bevel gear 65 to rotate. The transmission bevel gear 65 then drives the driven bevel gear 66 to rotate. Then, the driven bevel gear 66 drives the guide plate 52 to rotate, changing the airflow direction at the outlet of the air collector hood 51 and guiding the airflow to different surfaces of the coated parts, so that the hot air can better cover the coated parts and improve the drying efficiency.

[0038] Considering that the hot air discharged from drying oven 3 usually contains a large amount of heat, therefore, as Figures 1-7 As shown, a U-shaped exhaust pipe 31 is fixedly installed on one side of the drying oven 3 near the bottom, and an air inlet pipe 32 is fixedly installed on the top of the drying oven 3. The output end of the air inlet pipe 32 is connected to the receiving groove opened above the inner cavity of the drying oven 3. A dehumidification component 7 is sealed between the output end of the exhaust pipe 31 and the input end of the air inlet pipe 32. Excess heat-containing gas inside the drying oven 3 is discharged into the dehumidification component 7 through the exhaust pipe 31. After being dehumidified by the dehumidification component 7, it is transported back into the drying oven 3 through the air inlet pipe 32, realizing energy recovery and utilization, which helps to reduce the overall energy consumption of the drying and curing oven.

[0039] When dehumidifying with dehumidifying component 7, to make dehumidification more convenient, therefore, as Figure 7As shown, the dehumidification assembly 7 includes a dehumidification chamber 71 located on the top of the drying chamber 3 away from the rotating rod 61. A drying plate 72 is slidably disposed on one side of the inner cavity of the dehumidification chamber 71, and an activated carbon filter plate 73 is slidably disposed on the other side of the inner cavity of the dehumidification chamber 71. The gas with residual heat discharged from the inner cavity of the drying chamber 3 enters the dehumidification chamber 71 through the exhaust pipe 31. It first passes through the drying plate 72 to absorb moisture, and then passes through the activated carbon filter plate 73 to absorb odors in the gas before being discharged into the inner cavity of the drying chamber 3 through the air inlet pipe 32. By dehumidifying the discharged gas, it is beneficial to control the humidity of the air entering the drying and curing chamber, providing a more stable humidity environment for the drying and curing of coated parts, which helps to improve the drying quality and reduce quality problems caused by humidity changes.

[0040] To facilitate the transport of coated parts, a drying and curing process is performed. Therefore, such as Figure 1 and Figure 2 As shown, the conveying assembly 2 includes a concave frame 21 symmetrically arranged on the top of the base 1. A drive roller 22 is rotatably arranged on one side of the inner cavity of the frame 21, and a driven roller 23 is rotatably arranged on the other side of the inner cavity of the frame 21. A base belt 24 is arranged between the surfaces of the drive roller 22 and the driven roller 23. When the coating on the surface of the coated part needs to be cured, the door at the entrance of the drying chamber 3 is opened, and then the coated part is placed on top of the base belt 24. The motor is started to drive the drive roller 22 to rotate. When the drive roller 22 rotates, friction is generated between its surface and the base belt 24, causing the base belt 24 to rotate. The base belt 24 moves the coated part on top to the inner cavity of the drying chamber 3, which facilitates the conveying of the coated part into the inner cavity of the drying chamber 3 and is beneficial for subsequent curing work.

[0041] In practical use, this utility model of a surface treatment device for coated parts with high-efficiency anti-corrosion function involves opening the door at the entrance of the drying chamber 3, placing the coated part on top of the base belt 24, and starting the motor to drive the transmission roller 22 to rotate. As the transmission roller 22 rotates, friction is generated between its surface and the base belt 24, causing the base belt 24 to rotate. The base belt 24 then moves the coated part from the top into the inner cavity of the drying chamber 3. Simultaneously, the heating mesh 43 is activated to raise the temperature, and the motor is started to drive the rotating shaft 41 to rotate. The rotating shaft 41 drives the bottom fan blades 42 to rotate, blowing the heat generated by the heating mesh 43 onto the surface of the workpiece and the surrounding environment. The hot air blown out by the fan blades 42 is then concentrated on the surface of the coated part after passing through the air collector shroud 51, allowing the coating to penetrate more effectively. The solvent evaporates more quickly. When the rotating shaft 41 drives the fan blades 42 to rotate, it will drive the transmission pulley 62 on the upper surface to rotate. Then, the surface of the transmission pulley 62 and the belt 64 will generate friction, thereby driving the belt 64 to rotate. Similarly, the belt 64 will drive the driven pulley 63 to rotate. The driven pulley 63 will drive the rotating rod 61 fixedly connected to it to rotate. When the rotating rod 61 rotates, it will drive the transmission bevel gear 65 at the bottom to rotate. The transmission bevel gear 65 will then drive the driven bevel gear 66 to rotate. Then the driven bevel gear 66 will drive the guide plate 52 to rotate. This conveniently drives multiple fan blades 42 and guide plates 52 to rotate simultaneously, which is beneficial to change the airflow direction at the outlet of the air collector hood 51 and facilitates subsequent drying work.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
