Description

Technical Field

[0001] The utility model relates to the technical field of steel plate processing, in particular to a surface pretreatment device for steel plate processing. Background Technique

[0002] Through painting construction, the coating is formed on the surface of the steel plate to play its functions such as decoration, protection and special functions. The main painting equipment is divided into surface pretreatment equipment before painting, painting equipment, film drying and curing equipment, mechanized conveying equipment, dust-free constant temperature and humidity air supply equipment and other auxiliary equipment. The purpose of pretreatment is to remove the rust spots on the surface of the steel plate and provide a good base suitable for painting requirements.

[0003] The publicly disclosed CN208451395U discloses a surface pretreatment device for steel plate painting, including a base and a treatment box. The treatment box is fixedly installed on the top of the base. A steel plate fixing table is fixedly installed on the top of the base. A plurality of negative pressure adsorption notches are arranged on the steel plate fixing table. The gap between the steel plate fixing table and the inner wall of the treatment box forms a waste collection groove. Side slide rails are installed on the opposite sides inside the treatment box. A sliding seat is slidably installed on the side slide rails. A movable plate is fixedly connected between the sliding seats. The top of the movable plate is connected to a telescopic cylinder installed on the top of the treatment box through a piston rod. A sandblasting pipe and an air jet pipe are fixedly installed at the bottom of the movable plate. A plurality of sandblasting guns are fixedly installed at the output end of the sandblasting pipe. The input end of the sandblasting pipe is connected to a sandblaster through a material guiding pipe. An air jet nozzle is installed at the output end of the air jet pipe. The input end of the air jet pipe is connected to the output end of a blower through an air delivery pipe. Although this surface pretreatment device realizes the fixation of the steel plate during the sandblasting process and moves the sandblasting gun installed up and down, effectively improving the sandblasting and rust removal effect. However, in this surface pretreatment device, the steel plate is fixed during the sandblasting process. This design limits the coverage range of the sandblasting gun, making it only able to spray on the fixed surface area of the steel plate. Since the steel plate does not rotate, the sandblasting gun cannot fully contact the entire surface of the steel plate, resulting in some areas not being fully processed. This phenomenon of insufficient local sandblasting will cause uneven rust removal on the surface of the steel plate, and some rust stains and impurities may remain on the surface, affecting the overall rust removal effect. Therefore, improvement is needed. Content of the Utility Model

The material of the supporting feet 14 can be selected from stainless steel or high-strength plastic. Stainless steel has excellent corrosion resistance and can adapt to humid and corrosive environments, while high-strength plastic has the advantages of light weight and strong impact resistance, ensuring the stability and durability of the equipment during long-term use. The top surface of the base 1 is fixedly installed with a support beam 2, the top surface of the support beam 2 is fixedly installed with a cylinder 3, and the output end of the cylinder 3 is installed with a sandblasting chamber 4. The bottom surface of the sandblasting chamber 4 is communicated with sandblasting guns 5, and the sandblasting guns 5 are arranged at equal distances on the bottom surface of the sandblasting chamber 4 to ensure uniform sandblasting effect. The top surface of the sandblasting chamber 4 is communicated with a material guiding pipe 6 and a blower 7.

[0025] Please refer to Figures 1-5 , the top surface of the base 1 is rotatably connected with a rotating column 8, and the top end of the rotating column 8 is fixedly installed with a steel plate fixing table 9. The surface of the rotating column 8 is fixedly installed with a worm gear 10, and the worm gear 10 is connected to the rotating column 8 by a key to ensure no slipping during the transmission process. The top surface of the base 1 is fixedly installed with a vertical plate 11, the surface of the vertical plate 11 is fixedly installed with a motor 12, the output end of the motor 12 is installed with a worm 13, and the worm 13 meshes with the worm gear 10. The worm 13 and the worm gear 10 are processed with high precision to ensure smooth and efficient transmission. The worm 13 is driven by the motor 12 to rotate, driving the worm gear 10 and the rotating column 8 to rotate synchronously, so as to realize the rotation function of the steel plate fixing table 9. Place the steel plate to be processed on the steel plate fixing table 9, and then turn on the motor 12. The motor 12 can drive the worm 13 to rotate, the worm 13 drives the meshing worm gear 10 to rotate, and the worm gear 10 drives the rotating column 8 to rotate, so that the steel plate fixing table 9 rotates. This enables the surface of the steel plate to fully contact the sand during sandblasting by the sandblasting guns 5, thereby improving the sandblasting effect. During sandblasting, the cylinder 3 drives the sandblasting chamber 4 and the sandblasting guns 5 to move downward, the material guiding pipe 6 feeds sand, the blower 7 feeds air, and finally sandblasting is carried out through the sandblasting guns 5. The sandblasting chamber 4 is made of high-strength alloy material to ensure its durability and stability in a high-pressure working environment. Embodiment

[0026] Please refer to Figures 4-5 On the back of the base 1, a grinding mechanism is provided. The grinding mechanism includes a sliding plate 15 which is slidably connected to the back of the base 1. The sliding plate 15 is connected through a guiding slide rail to ensure the smoothness and precision during its sliding process. At the top end of the sliding plate 15, a top plate 16 is fixedly installed. On the top surface of the top plate 16, a pull handle 21 is fixedly installed. The pull handle 21 is made of PP plastic. The PP plastic material is strong and durable, with good impact resistance and wear resistance, ensuring comfort and safety during operation. At the bottom surface of the top plate 16, a grinding stone 17 is fixedly installed. The material of the grinding stone 17 can be selected from emery or silicon carbide. The grinding stone 17 made of emery has extremely high hardness and wear resistance, and is suitable for high-intensity grinding operations, while the silicon carbide material has good thermal conductivity and corrosion resistance. At the bottom end of the sliding plate 15, a bottom block 18 is fixedly installed. On the bottom surface of the base 1, a short rod 19 is fixedly installed. The bottom block 18 is slidably connected to the short rod 19. Through the guiding action of the short rod 19, it is ensured that the grinding mechanism can move smoothly during use. The short rod 19 is slidably connected to the bottom block 18. A spring 20 is sleeved on the surface of the short rod 19. One end of the spring 20 is fixedly connected to the bottom block 18, and the other end is fixedly connected to the base 1. The spring 20 is made of spring steel material and has good elasticity and durability. The spring 20 made of spring steel material has high strength and fatigue resistance, and can maintain stable elastic force and service life for a long time. When the steel plate rotates and is fixed on the steel plate fixing table 9, due to the elastic force of the spring 20, the spring 20 can drive the bottom block 18 to move downward. The bottom block 18 drives the sliding plate 15 to slide downward. The sliding plate 15 drives the top plate 16 to move downward. The top plate 16 drives the grinding stone 17 to fit the steel plate. In this way, when the steel plate rotates, the steel plate can also be ground by the grinding stone 17 to fully remove rust stains and impurities on the surface, improving the sandblasting processing effect. In the present utility model, during the rotation of the steel plate, the surface of the steel plate is pre-ground by the grinding stone 17, which can effectively remove rust stains and impurities on the surface of the steel plate, provide a cleaner surface for subsequent sandblasting treatment, and thus improve the sandblasting effect and coating adhesion.

[0027] Working principle: Place the steel plate to be processed on the steel plate fixing table 9, and then turn on the motor 12. At this time, the motor 12 can drive the worm 13 to rotate. At this time, the worm 13 can drive the worm wheel 10 meshed with it to rotate. Subsequently, the worm wheel 10 can drive the rotating column 8 to rotate, thereby rotating the steel plate fixing table 9, so that the steel plate can rotate. In this way, when sandblasting is carried out through the sandblasting gun 5, the surface of the steel plate can be more fully contacted with the sandblasting, thereby improving the sandblasting effect. When sandblasting, the cylinder 3 drives the sandblasting chamber 4 and the sandblasting gun 5 to move downward, and then sand can enter through the material guiding pipe 6, and the blower 7 blows air. Finally, sandblasting is carried out through the sandblasting gun 5. In this utility model, through the transmission mechanism of the worm 13 and the worm wheel 10, the steel plate fixing table 9 is driven to rotate, so that the steel plate can rotate evenly during the sandblasting process, thereby ensuring that the entire surface of the steel plate can be in full contact with the sandblasting, avoiding insufficient sandblasting in local areas, and improving the overall rust removal effect. And the rotating steel plate fixing table 9 enables the sandblasting gun 5 to cover the entire surface of the steel plate in a more efficient manner, reducing the time of the sandblasting operation and improving the work efficiency. The rotating steel plate can better receive the sandblasting, the cleaning effect is more thorough, and the coating adhesion is stronger, thereby improving the processing quality of the steel plate, and the quality of the final product is also improved. When the steel plate rotates on the steel plate fixing table 9, at this time, due to the elastic force of the spring 20, the spring 20 can drive the bottom block 18 to move downward. Subsequently, the bottom block 18 can drive the sliding plate 15 to slide downward. Then, the sliding plate 15 can drive the top plate 16 to move downward. Subsequently, the top plate 16 can drive the grinding stone 17 to fit the steel plate. In this way, when the steel plate rotates, the steel plate can also be ground by the grinding stone 17, which can fully remove the rust and impurities on the surface and improve the sandblasting processing effect. In this utility model, during the rotation of the steel plate, the surface of the steel plate is pre-ground by the grinding stone 17, which can effectively remove the rust and impurities on the surface of the steel plate, provide a cleaner surface for the subsequent sandblasting treatment, thereby improving the sandblasting effect and the coating adhesion. And when the steel plate rotates, grinding and sandblasting are carried out simultaneously, which can greatly improve the rust removal efficiency, reduce the processing time, and realize a more efficient surface pretreatment process. And through the double treatment of grinding first and then sandblasting, the surface of the steel plate is more flat and clean, and the sandblasting effect is more uniform and thorough, thereby improving the quality and durability of the coating.
