Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0025] See Figures 1-4 A surface treatment device for rolled steel plates includes a main body 1 and a surface treatment mechanism 2, with the surface treatment mechanism 2 disposed above the main body 1.

[0026] The surface treatment mechanism 2 includes a feeding assembly 21 located on the upper left side of the main body 1, a rinsing assembly 22 installed on the right side of the feeding assembly 21, and a polishing assembly 23 located on the right side of the rinsing assembly 22.

[0027] In this utility model, the feeding assembly 21 includes a drive motor 211 installed at the front end of the device body 1, and a conveyor belt 212 installed on the inner side of the device body 1. The surface of the conveyor belt 212 is made of rubber. The steel plate is moved by the conveyor belt 212 to feed the steel plate, which facilitates continuous cleaning of the steel plate.

[0028] In this utility model, the rinsing assembly 22 includes a rinsing connecting frame 221 welded to the middle section of the main body 1 of the device. A rinsing pipe 222 is installed on the inner side of the rinsing connecting frame 221. A high-pressure nozzle 223 is installed at the bottom end of the rinsing pipe 222. When the steel plate moves, the surface of the steel plate is rinsed under high pressure by the high-pressure nozzle 223 to quickly cool down the rolled steel plate and remove impurities from the surface of the steel plate to ensure the cleanliness of the steel plate surface.

[0029] In this utility model, a connecting support plate 224 is provided on the right side of the high-pressure nozzle 223, and a cleaning scraper 225 is fixedly connected to the right side of the connecting support plate 224. The cleaning scraper 225 is made of rubber and is in contact with the surface of the main body 1 of the device. The cleaning scraper 225 scrapes the steel plate when it moves to remove excess moisture from the surface of the steel plate and remove impurities at the same time, so as to prevent impurities from entering under the rotating grinding disc 235 and causing the steel surface to be scratched.

[0030] In this utility model, the grinding component 23 includes a grinding connecting frame 231 installed on the right side of the main body 1 of the device. A hydraulic lifting shaft 232 is installed on the inner side of the grinding connecting frame 231. A fixed mounting bracket 233 is welded to the bottom end of the hydraulic lifting shaft 232. The lifting and lowering of the hydraulic lifting shaft 232 drives the rotating grinding disc 235 to be lifted and lowered, which facilitates the adjustment of the rotating grinding disc 235 according to the thickness of the rolled steel plate, so as to ensure the grinding effect.

[0031] In this utility model, a servo motor 234 is installed inside the fixed mounting bracket 233, and a rotating grinding disc 235 is installed at the bottom of the servo motor 234. The servo motor 234 drives the rotating grinding disc 235 to rotate and grind, so as to flatten the surface of the steel plate and remove minor defects, thereby improving the quality of the steel plate.

[0032] In this utility model, a pressing component 3 is provided above the feeding component 21. The pressing component 3 includes a support frame 31 welded to the top left side of the main body 1 of the device. A hydraulic push rod 32 is installed on the inner side of the support frame 31. An auxiliary pressing belt 33 is installed at the bottom end of the hydraulic push rod 32. The surface of the auxiliary pressing belt 33 is made of rubber. According to the thickness of the rolled steel plate, the auxiliary pressing belt 33 is driven by the hydraulic push rod 32 to press the steel plate, thereby increasing the stability of the steel plate during conveying and preventing the steel plate from shaking due to the rotation of the grinding disc 235, thus ensuring the grinding effect of the steel plate.

[0033] As can be seen from the above technical solution, in use, the device is installed at the required location, and then the steel plate is fed and moved by the conveyor belt 212. While the steel plate is moving, the surface of the steel plate is subjected to high-pressure washing by the high-pressure nozzle 223 to quickly cool the rolled steel plate and remove impurities from the surface, ensuring the cleanliness of the steel plate surface. Then, the cleaning scraper 225 scrapes the steel plate as it moves to remove excess moisture and impurities, preventing impurities from entering below the rotating grinding disc 235 and causing scratches on the steel surface. Finally, the servo motor 234 drives the rotating grinding disc... The grinding disc 235 rotates and grinds to flatten the surface of the steel plate and remove minor defects, thereby improving the quality of the steel plate. At the same time, the hydraulic lifting shaft 232 drives the rotating grinding disc 235 to rise and fall, which can be adjusted according to the thickness of the rolled steel plate to ensure the grinding effect. During grinding, according to the thickness of the rolled steel plate, the hydraulic push rod 32 drives the auxiliary pressure belt 33 to press the steel plate tightly, increasing the stability of the steel plate during transportation and preventing the steel plate from shaking due to the rotation of the grinding disc 235, thus ensuring the grinding effect of the steel plate. This completes the use of a surface treatment device for rolled steel plates.
