[0002] With the continuous development of society, aluminum coils and aluminum sheets have developed rapidly. Aluminum sheets have low density but relatively high strength, close to or exceeding high-quality steel, good plasticity, can be processed into various profiles, and have excellent electrical conductivity, thermal conductivity and corrosion resistance. They are widely used in industry and are a commonly used metal material in the fields of home decoration, mechanical equipment, etc. During the production and processing of aluminum sheets, they need to enter the spraying room to spray primer and topcoat on the surface. In order to improve the surface adhesion of aluminum during the spraying process, the surface of the aluminum sheet needs to be polished.

[0003] In the existing double-sided grinding devices, the distance between the top grinding roller and the bottom grinding roller is often not adjustable or has a limited adjustment range. Since aluminum plates of different thicknesses require different grinding spacings, if the grinding spacing is fixed, it cannot adapt to aluminum plates of different thicknesses, resulting in poor grinding effects and may even damage the aluminum plate or the grinding roller. Utility Model Content

[0004] The purpose of the utility model is to provide a double-sided grinding device for aluminum plates to solve the problem proposed in the above background technology that the distance between the top grinding roller and the bottom grinding roller in the existing double-sided grinding device is often not adjustable or has a limited adjustment range. Since aluminum plates of different thicknesses require different grinding intervals, if the grinding interval is fixed, it cannot adapt to aluminum plates of different thicknesses, resulting in poor grinding effect and even possible damage to the aluminum plate or the grinding roller.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-sided grinding device for an aluminum plate, comprising a workbench, a bottom grinding roller is fixedly installed at the center of the top of the workbench, a top frame is fixedly connected to the outer side of the top of the workbench, the bottom of the top frame is fixedly connected to fixed columns on both sides, a cylinder is fixedly installed at the center of the top of the top frame, the output end of the bottom of the cylinder passes through the bottom of the top frame and is fixedly connected to a movable plate, the bottom of the movable plate is fixedly connected to a support plate, movable grooves are provided on the opposite sides of the two fixed columns, and movable grooves are provided on the top positions on the opposite sides of the two fixed columns, the top grinding roller is rotatably connected to the support plate near the center position, two support rods are fixedly connected to one side of the movable groove, and the bottom of the support rods passes through the inside of the movable groove.

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] The double-sided grinding device for aluminum plates drives the movable plate to slide up and down in the movable groove of the fixed column through the telescopic action of the cylinder, thereby realizing the lifting and lowering function of the support plate and the top grinding roller thereon. This design allows the distance between the top grinding roller and the bottom grinding roller to be flexibly adjusted according to aluminum plates of different thicknesses. Therefore, whether it is a thinner aluminum plate or a thicker aluminum plate, a suitable grinding spacing can be obtained in this device to ensure the grinding quality and efficiency. The sliding connection between the movable plate and the movable groove and the sliding connection between the support rod and the sliding groove both enhance the stability and durability of the device. At the same time, the sleeve sliding connection between the sliding ring and the support rod provides additional support and stability for the movement of the support plate, ensuring that it is not easy to shake or deviate during the lifting process.

[0021] Working principle: First, place the aluminum plate to be polished on the conveyor body 3 and start the conveyor. The aluminum plate will be smoothly transported to the working area. At this time, the bottom grinding roller 2 has been fixed at the top center position of the workbench 1, ready to polish the bottom surface of the aluminum plate. Then, start the cylinder 6, and the telescopic rod of the cylinder 6 extends downward to push the movable plate 7 to move downward along the movable groove 12 of the fixed column 5. Since the movable plate 7 is fixedly connected to the support plate 8, the support plate 8 will also move downward. In the process of the support plate 8 descending, the reinforcing plate 16 on its top and the sliding ring 18 on the fixed plate 17 slide downward along the support rod 14 in the movable groove 13 of the fixed column 5. The sliding connection between the sliding ring 18 and the support rod 14 supports and stabilizes the movement of the support plate 8, further enhancing the structural stability of the device. As the support plate 8 moves downward, the top grinding roller 9 on it gradually Approaching the top surface of the aluminum plate, when the top grinding roller 9 contacts the top surface of the aluminum plate, start the drive motor 19, and the output end of the drive motor 19 drives the top grinding roller 9 to rotate, thereby starting to grind the top surface of the aluminum plate. At the same time, the auxiliary pressure roller 10 at the bottom of the support plate 8 performs auxiliary limiting on both sides of the aluminum plate to prevent the aluminum plate from offsetting or sliding during the grinding process. This design ensures the stability of the aluminum plate during the grinding process and the uniformity of the grinding. During the grinding process, the distance between the top grinding roller 9 and the bottom grinding roller 2 can be controlled according to the thickness of the aluminum plate by adjusting the expansion and contraction amount of the cylinder 6, so as to meet the grinding needs of aluminum plates of different thicknesses. This flexible adjustment function enables the device to be suitable for aluminum plates of different specifications, thereby improving the versatility and practicality of the device. Finally, after the aluminum plate passes through the double-sided grinding area, the conveying device body 2 4 will continue to transport it to the next process to complete the entire grinding process.

[0022] To sum up: the double-sided grinding device for aluminum plates, through the telescopic action of the cylinder 6, drives the movable plate 7 to slide up and down in the movable groove 12 of the fixed column 5, thereby realizing the lifting function of the support plate 8 and the top grinding roller 9 thereon. This design allows the distance between the top grinding roller 9 and the bottom grinding roller 2 to be flexibly adjusted according to the aluminum plates of different thicknesses. Therefore, whether it is a thinner aluminum plate or a thicker aluminum plate, a suitable grinding spacing can be obtained in this device to ensure the grinding quality and efficiency. The sliding connection between the movable plate 7 and the movable groove 12 and the sliding connection between the support rod 14 and the sliding groove 15 enhance the stability and durability of the device. At the same time, the sleeve sliding connection between the sliding ring 18 and the support rod 14 provides additional support and stability for the movement of the support plate 8, ensuring that it is not easy to shake or deviate during the lifting process.
