[0002] Metal sheets are flat rectangular plates made of metal as the base material and processed through specific processes. Metal sheet surface spraying is a surface treatment technology that uses specific processes to uniformly coat the surface of metal sheets to improve their appearance, enhance their performance, or endow them with special functions. Metal sheet surface renovation spraying is a comprehensive process that uses specific processes and techniques to repair, clean, pre-treat, and coat the surface of aged, corroded, or damaged metal sheets in order to restore their original performance, extend their service life, and improve their appearance quality.

[0003] Currently, there are various metal sheet surface renovation and spraying devices on the market. These devices have achieved basic functions such as cleaning, spraying, and drying of metal sheets to a certain extent. In the cleaning process, traditional devices mostly use fixed cleaning air nozzles to clean dust from the surface of metal sheets. The spray angle is relatively fixed. When dealing with complex curved surfaces or irregularly shaped metal sheets, the fixed nozzles are difficult to cover dead corner areas, and dust residue is likely to appear in the dead corners. Therefore, a metal sheet surface renovation and spraying device is proposed to solve the above problems. Utility Model Content

Two electric telescopic rods are fixedly mounted on the inner right side of the support frame, and a connecting plate is fixedly mounted on the outside of the electric telescopic rods. A movable frame is fixedly mounted on the outside of the connecting plate, and racks are fixedly mounted on the inner upper and lower walls of the movable frame.

[0006] Furthermore, the air compressor is fixedly connected to the air nozzle via an air pipe, and the rotating rod passes through the movable frame and is movably connected to the movable frame.

[0007] Furthermore, the half gear meshes with the rack, and the half gear is located inside the movable frame.

[0014] 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.

[0015] Please see Figure 1-4 The metal sheet surface renovation spraying device in this embodiment includes a frame 1, a dust removal device 2 installed on the top of the frame 1, a spraying device 3 fixedly installed on the top of the frame 1, a drying device 4 fixedly installed on the top of the frame 1, and a conveyor belt 5 installed inside the frame 1.

[0016] The dust removal device 2 includes a support frame 201. The support frame 201 is fixedly installed on the top of the frame 1. An air compressor 202 is fixedly installed on the top of the support frame 201. A rotating rod 203 is rotatably installed inside the support frame 201. An air nozzle 204 is fixedly installed on the outside of the rotating rod 203. A half gear 205 is fixedly installed on the outside of the rotating rod 203. Two electric telescopic rods 206 are fixedly installed on the inner right side of the support frame 201. A connecting plate 207 is fixedly installed on the outside of the electric telescopic rods 206. A movable frame 208 is fixedly installed on the outside of the connecting plate 207. A rack 209 is fixedly installed on the inner upper and inner lower walls of the movable frame 208.

[0017] exist Figure 1 In the process, the air compressor 202 continuously compresses the air, so that the air ejected from the air nozzle 204 is compressed air. As the pressure increases, it can blow away the dust remaining on the surface of the metal sheet.

[0018] exist Figure 1 In the spraying equipment 3, the specific equipment includes a spray gun, a storage tank, a pump, pipes, a PLC, sensors, and a data acquisition device, which can achieve uniform spraying on the surface of metal sheets and also allow for precise control of spraying parameters.

[0019] exist Figure 1 In the drying equipment 4, the specific structure consists of an infrared quartz tube, a PLC, and a touch screen control device. The infrared quartz tube is used to electrically heat and dry the surface of the metal sheet. The PLC and touch screen control device precisely adjust the temperature and time to ensure the drying quality.

[0020] During implementation, the following steps are performed: When in use, the metal sheet is passed sequentially through the bottom of the dust removal device 2, the spraying device 3, and the drying device 4 via the conveyor belt 5 to complete the cleaning, spraying, and drying of the metal sheet. The angle of the air nozzle 204 is adjusted by the metal sheet with different surfaces, which causes the blowing angle of the air nozzle 204 to change, so that the air nozzle 204 can adapt to metal sheets with various curved surfaces, reduce dust residue at the four corners, and improve the spraying efficiency of the metal sheet.

[0021] In summary, the metal sheet is sequentially passed through the bottom of the dust removal device 2, the spraying device 3, and the drying device 4 via the conveyor belt 5, completing the cleaning, spraying, and drying of the metal sheet. The angle of the air nozzle 204 is adjusted by the different surfaces of the metal sheet. The two electric telescopic rods 206 are activated, which moves the moving frame 208. When the rack 209 moves, the half gear 205 rotates, causing the rotating rod 203 to rotate synchronously, thus changing the blowing angle of the air nozzle 204. This allows the air nozzle 204 to adapt to various curved metal sheets, reducing dust residue in the four corners and improving the spraying efficiency of the metal sheet. This solves the problem that currently, there are various metal sheet surface renovation spraying devices on the market. These devices have achieved basic functions such as cleaning, spraying, and drying of metal sheets to a certain extent. In the cleaning stage, traditional devices mostly use fixed cleaning air nozzles to clean dust from the surface of the metal sheet. The spray angle is relatively fixed. When dealing with complex curved or irregularly shaped metal sheets, the fixed nozzles are difficult to cover dead corner areas, and dust residue is likely to occur in the dead corners.
