[0032] It should be noted that by pulling the first limit rod 34, the two sliders 35 can be moved away from each other. By loosening the first limit rod 34, the first spring 36 pushes the slider 35 to return to its original position. The inner side of the slider 35 is slidably connected to the upper wall of the guide rail 2 on both sides, thereby fixing the placement rack 31, so that the placement rack 31 does not deflect and can only move forward and backward.

[0034] It should be noted that the first limiting rod 34 is pulled until the slot 37 is aligned with the card plate 382. At this time, the second spring 384 pushes the circular plate 383 to move the second limiting rod 381 backward, so that the card plate 382 is movably sleeved into the inner side of the slot 37, so that the first limiting rod 34 is fixed, which is convenient for the installation of the slider 35.

[0036] It should be noted that when the push block 51 is located on the upper side of the conveyor belt 4, the vertical surface faces backward. When the placement rack 31 moves backward, the inclined surface of the push block 51 is pushed to cause the push block 51 to move downward. When the push block 51 is no longer restricted, the third spring 52 pushes the push block 51 to reset, and the conveyor belt 4 drives the push block 51 to move, so that the vertical surface of the push block 51 pushes the placement rack 31 to cause the quartz plate to move.

[0037] like Figure 1 , Figure 5As shown, the first grinding mechanism 8 includes a first motor 81, the lower surface of the first motor 81 is fixedly connected to the upper side of the movable platform 6 located in the middle, the output end of the first motor 81 is fixedly connected to a first connecting plate 82, and the side of the first connecting plate 82 close to the guide rail 2 is fixedly connected to a plurality of annularly distributed first telescopic rods 83, the outer walls of the plurality of first telescopic rods 83 are movably sleeved with a fourth spring 84, and the end of the first telescopic rod 83 close to the guide rail 2 is fixedly connected to a first grinding wheel 85.

[0038] It should be noted that the first motor 81 drives the first connecting plate 82 to rotate.

The first grinding wheel 85 grinds the side of the quartz plate.

[0039] like Figure 1 , Figure 6 As shown, the second grinding mechanism 9 includes a second motor 91, the lower side of the second motor 91 is fixedly connected to the front side of the space on the upper side of the moving platform 6 located on the rear side, the output end of the second motor 91 is fixedly connected to the first bevel gear 92, the lower side of the first bevel gear 92 is meshingly connected to the second bevel gear 93, the lower side of the second bevel gear 93 is rotatably connected to the upper side of the moving platform 6 located on the rear side, the upper side of the second bevel gear 93 is fixedly connected to a plurality of annularly distributed second telescopic rods 94, the outer walls of the plurality of second telescopic rods 94 are movably sleeved with sixth springs 95, and the upper end of the second telescopic rod 94 is fixedly connected to a second grinding wheel 96.

[0040] It should be noted that the second motor 91 drives the first bevel gear 92 to rotate, and when the first bevel gear 92 rotates, it drives the second bevel gear 93 to rotate, and when the second bevel gear 93 rotates, it drives the second telescopic rod 94 to revolve, so that the second grinding wheel 96 rotates, and the second grinding wheel 96 grinds the lower edge of the quartz plate.

[0041] like Figure 6 As shown, a second screw 97 is fixedly connected to the upper axis of the second bevel gear 93, and a mounting platform 98 is movably connected to the outer wall of the second screw 97 near the upper side, and a plurality of annularly distributed third telescopic rods 99 are fixedly connected to the lower side of the mounting platform 98, and a seventh spring 910 is movably connected to the outer walls of the plurality of third telescopic rods 99, and a third grinding wheel 911 is fixedly connected to the lower side of the seventh spring 910, and a limiting nut 912 is rotatably connected to the upper side of the mounting platform 98, and the inner side of the limiting nut 912 is threadedly connected to the outer wall of the second screw 97.

[0042] It should be noted that rotating the limit nut 912 can drive the mounting platform 98 to move up and down. There is a convex strip on the inner side of the mounting platform 98, and the convex strip is slidably connected to the groove on the outer wall of the second screw 97 to prevent the mounting platform 98 from rotating with the limit nut 912 when the limit nut 912 is rotated. The second screw 97 drives the mounting platform 98 to rotate, causing the third telescopic rod 99 to revolve, causing the third grinding wheel 911 to rotate, and the third grinding wheel 911 to grind the edge of the upper side of the quartz plate.

[0043] The working principle of the utility model is as follows: first, the first motor 81 drives the first connecting plate 82 to rotate, and when the first connecting plate 82 rotates, it drives the first telescopic rod 83 to revolve, so that the first grinding wheel 85 rotates, and the first grinding wheel 85 grinds the side of the quartz plate. The second motor 91 drives the first bevel gear 92 to rotate, and when the first bevel gear 92 rotates, it drives the second bevel gear 93 to rotate, and when the second bevel gear 93 rotates, it drives the second telescopic rod 94 to revolve, so that the second grinding wheel 96 rotates, and the second grinding wheel 96 grinds the lower edge of the quartz plate. The limiting nut 912 is rotated to drive the mounting table 98 to move up and down. There is a convex strip on the inner side of the mounting table 98, and the convex strip is slidably connected to the first The groove on the outer wall of the second screw 97 prevents the mounting platform 98 from rotating with the limiting nut 912 when the limiting nut 912 rotates, and the second screw 97 drives the mounting platform 98 to rotate, so that the third telescopic rod 99 revolves, so that the third grinding wheel 911 rotates, and the third grinding wheel 911 grinds the edge of the upper side of the quartz plate, and the first motor 81 and the second motor 91 drive the first grinding wheel 85, the second grinding wheel 96 and the third grinding wheel 911 to rotate, so that the side and the upper and lower sides of the edge of the quartz plate are grinded, thereby increasing the efficiency, relying on the first telescopic rod 83 and the fourth spring 84, the second telescopic rod 94 and the sixth spring 95, and the third telescopic rod 83. The cooperation between 99 and the seventh spring 910 makes the first grinding wheel 85, the second grinding wheel 96 and the third grinding wheel 911 close to the outer surface of the quartz plate, making the grinding more thorough. Finally, the first screw rod 33 is rotated to make the first screw rod 33 move up and down. The lower end of the first screw rod 33 and the lower side of the placement rack 31 jointly clamp the side of the quartz plate to achieve the purpose of fixing the quartz plate. Pulling the first limit rod 34 can make the two sliders 35 move away from each other. Loosening the first limit rod 34, the first spring 36 pushes the slider 35 to reset, and the inner side of the slider 35 is slidably connected to the two sides of the upper wall of the guide rail 2 to fix the placement rack 31, so that the placement rack 31 is fixed. 1 can only move forward and backward without deflection. When the push block 51 is located on the upper side of the conveying crawler 4, the vertical surface is backward. When the placement rack 31 moves backward, the inclined surface of the push block 51 is pushed to cause the push block 51 to move downward. When the push block 51 is no longer restricted, the third spring 52 pushes the push block 51 to reset, and the conveying crawler 4 drives the push block 51 to move, so that the vertical surface of the push block 51 pushes the placement rack 31 to cause the quartz plate to move. The front and rear sides of the quartz plate are fixed by the two fixing mechanisms 3, and the fixing mechanism 3 is pushed to move it onto the conveying crawler 4. The conveying crawler 4 drives the pushing mechanism 5 to rotate, so that the pushing mechanism 5 pushes the fixing mechanism 3 to move, thereby achieving the purpose of automatic feeding, which is safer and more convenient to operate.
