Description

Technical Field

[0001] The invention belongs to the technical field of plate polishing, and in particular relates to an automatic flattening and polishing device for plate processing. Background Art

[0002] Plate grinding and polishing are common processes in plate processing. The surface finish of the plate directly impacts the quality of the product, particularly in architectural decoration, furniture, and electronics. Surface polishing can also be used in mass production to eliminate color variations and processing marks, ensuring surface consistency across batches or components. Polishing metal plate surfaces removes oxide layers and micropores, facilitating subsequent coating, electroplating, or anodizing, enhancing rust and corrosion resistance. Polishing transparent materials like glass and acrylic can reduce light scattering and improve transmittance or reflectivity (e.g., mirrors and display panels).

[0003] When polishing a plate, the plate is generally fixed first, and then the surface of the plate is polished by holding the plate or using a mechanical arm to drive the polishing wheel. For example, a plate polishing device disclosed in publication number CN222222185U first places the plate to be polished on a rack, abuts the junction of the two sides of the plate against two buffer plates, positions the plate on the rack, and then polishes the upper end of the plate with a polishing wheel.

[0004] Although the existing plate polishing device can realize plate polishing, when polishing both the upper and lower ends of the plate, the plate is fixed on the clamp, and one end of the plate is polished. After polishing one end of the plate is completed, the plate is removed from the clamp, turned over and re-fixed on the clamp to polish the other end. This requires clamping and disassembling the plate twice, which makes the plate polishing operation more complicated. Summary of the Invention

It also prevents dust from overflowing when polishing the plate. The suction head can absorb the heat on the polishing shaft to avoid heat accumulation and prevent heat from causing physical changes on the plate surface, such as expansion and deformation, which will affect the uniformity and accuracy of polishing. It also prevents the polishing shaft from working in a high temperature environment and accelerating the wear of the polishing tool.

[0019] 3. A support plate that can move up and down is set above and below the movable plate. The support plate supports the surface of the plate, thereby preventing the polishing shaft from exerting pressure on the plate during polishing, which may cause deformation of the plate.

[0020] 4. Through the setting of the unloading plate, feeding plate, supporting plate and supporting block, workers can place the plate on the feeding plate and remove the plate from the unloading plate, so as to avoid delaying the grinding and polishing device from grinding and polishing the plate due to loading and unloading.

[0042] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 7 As shown, as a preferred embodiment of the present invention, the elastic telescopic rod 106 includes a telescopic sleeve 1061, a telescopic rod 1062 and a tension spring 1063, the telescopic rod 1062 is slidably connected in the telescopic sleeve 1061, the two ends of the tension spring 1063 are respectively connected to the telescopic sleeve 1061 and the telescopic rod 1062, the telescopic sleeve 1061 is rotatably connected to the inner wall of the frame 101, the telescopic end of the hydraulic cylinder 108 is rotatably connected to the telescopic sleeve 1061, and the polishing shaft 107 is rotatably connected to the telescopic rod 1062.

[0043] In the embodiment of the present invention, when the polishing shaft 107 contacts the plate, the tension spring 1063 pulls the telescopic rod 1062 , and the telescopic rod 1062 drives the polishing shaft 107 to press against the plate.

[0045] In the embodiment of the present invention, the second motor 401 drives the driving gear 402 to rotate, the driving gear 402 drives the transmission gear to rotate, and the transmission gear drives the polishing shaft 107 to rotate.

[0046] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 10 、 Figure 11 、 Figure 12As shown, as a preferred embodiment of the present invention, a negative pressure tube 701 is arranged between the two elastic telescopic rods 106, and the two ends of the negative pressure tube 701 are respectively rotatably connected to the two telescopic rods 1062, and a plurality of suction heads 702 are installed on the negative pressure tube 701, one end of the negative pressure tube 701 is connected to the hose of the vacuum cleaner, and the other end of the negative pressure tube 701 is connected to a swing rod 705, and a fixed shaft 706 is fixed on the swing rod 705, and a fan-shaped sink groove 1 704 is provided on the telescopic rod 1062, and the swing rod 705 is rotatably connected in the fan-shaped sink groove 1 704, and a torsion spring 703 is fixed on the negative pressure tube 701, and the end of the torsion spring 703 is fixed on the telescopic rod 1062, and a fan-shaped sink groove 2 707 is provided on the inner wall of the frame 101, and the fixed shaft 706 is movably provided in the fan-shaped sink groove 2 707.

[0047] 704 , which will affect the polishing effect and the service life of the polishing shaft 107.

[0048] When the hydraulic cylinder 108 contracts, the telescopic sleeve 1061 and the telescopic rod 1062 drive the polishing shaft 107 to move below the movable plate 103. During this process, the telescopic rod 1062 drives the swing rod 705 and the fixed shaft 706 to move downward until the fixed shaft 706 contacts the lower end of the fan-shaped sink groove 2 707.

Under the guidance of the guide shaft 502, the second cylinder 503 drives the upper support plate 504 to move downward. The upper support plate 504 supports the upper end of the plate, thereby preventing the pressure of the polishing shaft 107 on the plate during the ground and polishing, which causes the plate to deform. The second cylinder 503 below the movable plate 103 contracts, and the lower support plate 504 is below the polishing shaft 107, thereby not affecting the movement of the polishing shaft 107 relative to the plate.

[0052] When the support plate 504 moves, it can drive the limiting screw rod 505 to move.

The clamping plate 201 cooperates with the inner wall of the placement groove 105 to fix the plate, thereby realizing automatic material removal before the plate is ground and polished;

[0057] The movable plate 103 drives the plate to move toward the polishing shaft 107. When the polishing shaft 107 contacts the upper end of the plate, the tension spring 1063 pulls the telescopic rod 1062. The telescopic rod 1062 drives the polishing shaft 107 to press against the upper surface of the plate. The rotating component 4 drives the polishing shaft 107 to rotate. The rotating polishing shaft 107 grinds and polishes the upper end of the plate. The supporting plate 504 below drives the supporting block 605 to support the lower end of the plate, thereby avoiding the pressure of the polishing shaft 107 on the plate during grinding and polishing, which causes deformation of the plate, until the movable plate 103 drives the plate to completely pass under the polishing shaft 107. Then the movable plate 103 drives the plate to move in the opposite direction and reset. The hydraulic cylinder 108 contracts. The hydraulic cylinder 108 drives the elastic telescopic rod 106 to rotate downward. The elastic telescopic rod 106 drives the polishing shaft 107 to be located under the movable plate 103.

[0058] The second cylinder 503 above the movable plate 103 extends, and under the guidance of the guide shaft 502, the second cylinder 503 drives the upper support plate 504 to move downward, and the upper support plate 504 supports the upper end of the plate, thereby preventing the pressure of the polishing shaft 107 on the plate during grinding and polishing, which causes deformation of the plate. The second cylinder 503 below the movable plate 103 contracts, and the lower support plate 504 is below the polishing shaft 107, thereby not affecting the movement of the polishing shaft 107 relative to the plate. The movable plate 103 drives the plate to pass over the polishing shaft 107, and the polishing shaft 107 grinds and polishes the lower end of the plate.

[0059] The second cylinder 503 below the movable plate 103 extends, and under the guidance of the guide shaft 502, the second cylinder 503 drives the support plate 504 below to move upward, and the support plate 504 below drives the supporting block 605 to support the lower end of the plate.
