[0001] The utility model belongs to the technical field of furniture plate processing, and in particular relates to a grinding and polishing device for plate materials. Background Art

[0002] Grinding and polishing is a method of processing the surface of a material, the main purpose of which is to obtain a specific surface roughness or a smooth and flat surface. After grinding and polishing, the sheet material can obtain a smooth surface, which is conducive to improving the adhesion of the paint surface and enhancing the overall aesthetics of the product. In addition, grinding and polishing can also remove the oxide layer and shallow marks on the surface of the sheet, further improving the quality and service life of the product.

[0003] When grinding the sheet material, if the sheet material itself is relatively thin and narrow, the angle of the edge of the sheet material may be worn away due to the inclination of the grinding workpiece during the grinding process, and excessive grinding may cause losses. In addition, it is troublesome to handle the thin and narrow sheets one by one, and the grinding progress is slow, which is not conducive to cost savings. Utility Model Content

[0004] Based on the problems mentioned in the above background technology, the utility model provides a grinding and polishing device for plate materials.

DETAILED DESCRIPTION

[0023] like Figure 1 to Figure 5 As shown, a grinding and polishing device for sheet material comprises a workbench 1, a mounting cover 3 and a grinding mechanism, wherein a clamping mechanism is arranged on the workbench 1, and the clamping mechanism comprises two clamping blocks 24, and the two clamping blocks 24 are slidably connected to the workbench 1 through an adjusting mechanism; the mounting cover 3 is arranged on the workbench 1, and a pressing mechanism is arranged on the rear wall of the mounting cover 3, and the pressing mechanism comprises a mounting box 4, and the mounting box 4 is arranged on the rear wall of the mounting cover 3 through a first moving mechanism, and a plurality of array-distributed pressing members 41 are hinged in the mounting box 4, and an angle between the end of the pressing member 41 exposed from the mounting box 4 and the bottom of the mounting box 4 is an acute angle, and an elastic member 42 is arranged between the pressing member 41 and the mounting box 4; the grinding mechanism is located on one side of the pressing mechanism, and is used for grinding sheet material 6.

[0024] By adopting the above technical scheme, the sheet material 6 is clamped by the two clamping blocks 24 of the clamping mechanism to prepare for grinding. The adjusting mechanism can adjust the clamping according to the amount of the sheet material 6. After the sheet material 6 is clamped, the mounting cover 3 moves downward under the drive of the first moving mechanism, and the plurality of pressing members 41 in the mounting box 4 contact one end of the plurality of sheet materials 6. Since the thickness of the sheet material 6 before grinding is uneven, and an elastic member 42 is provided in the mounting box 4, when the plurality of pressing members 41 contact the sheet material 6, the elastic member 42 produces different compression amounts for the sheet materials 6 of different thicknesses, thereby ensuring that each sheet material 6 can be pressed and there will be no situation where it cannot be fixed, thereby achieving simultaneous grinding of multiple sheet materials 6, providing a more stable surface, and avoiding excessive grinding.

[0025] As a preferred solution, the adjustment mechanism includes a mounting seat 2 and two adjustment blocks 21. The workbench 1 is provided with a sliding through hole 11. The two mounting seats 2 are arranged at the bottom of the workbench 1 at the two ends of the sliding through hole 11. The mounting seat 2 is rotatably connected with an adjustment screw 22. The adjustment screw 22 is driven by a motor. The threads at the two ends of the adjustment screw 22 are in opposite rotations. The two adjustment blocks 21 are respectively threadedly connected to the two ends of the adjustment screw 22. The adjustment block 21 is provided with a connecting column 23. The connecting column 23 passes through the sliding through hole 11 and is fixedly connected to the clamping block 24. The adjustment block 21 is restricted by the sliding through hole 11 to ensure that when the adjustment screw 22 rotates, the adjustment block 21 can only move in the sliding through hole 11. Since the threads at the two ends of the adjustment screw 22 are in opposite rotations, the adjustment block 21 will drive the two clamping blocks 24 to approach each other through the connecting column 23 to achieve clamping, or move away from each other to end clamping.

[0026] As a preferred solution, the grinding mechanism includes a mounting plate 5, which is connected to the mounting cover 3 through a second moving mechanism, and an electric track 51 perpendicular to the rear wall of the mounting cover 3 is provided on the mounting plate 5, and a slider 52 is connected to the electric track 51, and a mounting frame 53 is provided at the bottom of the slider 52, and a grinding roller 54 is rotatably connected to the mounting frame 53. The mounting plate 5 is driven downward by the second moving mechanism to make the grinding roller 54 contact the surface of the sheet 6 and start grinding. Driven by the slider 52, the grinding roller 54 is shifted while grinding to ensure that the sheet 6 is ground to the same plane. After the grinding is completed, the mounting box 4 is moved upward to continue to grind the part that has been pressed but not polished evenly.

[0027] As a preferred solution, the second moving mechanism is a hydraulic cylinder 32 fixedly mounted on the top of the mounting cover 3, and the output end of the hydraulic cylinder 32 is connected to the mounting plate 5. The mounting plate 5 is driven downward by the hydraulic cylinder 32 to achieve grinding and polishing.

[0028] As a preferred solution, a pressing block 43 is hingedly connected to the bottom of the pressing member 41. The hinged pressing block 43 contacts the surface of the sheet 6, ensuring that no matter how the angle of the pressing member 41 changes during the pressing process, the contact area between the pressing block 43 and the sheet 6 will not change, and the stable pressing of the pressing block 43 and the sheet 6 will not be affected.

[0029] As a preferred solution, the elastic member 42 is a rubber pad filled on the upper surface of the installation box 4 and the pressing member 41. The rubber pad controls the amount of contraction into the installation box 4 when different pressing members 41 press different heights of the sheet materials 6, ensuring that each sheet material 6 can be fixed and will not be unable to be fixed due to uneven heights.

[0030] As a preferred solution, the first moving mechanism is a rodless cylinder 31 fixedly mounted on the rear wall of the mounting cover 3, and the output end of the rodless cylinder 31 is connected to the mounting box 4. The mounting box 4 is moved up and down and positioned by the rodless cylinder 31, and the mounting box 4 is pressed down so that the pressing block 43 contacts the surface of the sheet 6 to achieve fixation.
