[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0022] Please refer to Figures 1-4 , the embodiments of the present application include:

[0023] As shown in Figure 1 and Figure 2 , the material pallet leg automatic polishing mechanism comprises a base 1, a negative pressure box 2, a support 19, a sand belt 4 and a first lifting driving mechanism 11. The negative pressure box 2 is horizontally arranged on the base 2 in a lifting manner. In the embodiment, the base 1 is provided with a second lifting driving mechanism 22 for driving the negative pressure box 2 to lift. The second lifting driving mechanism 22 comprises a screw rod lifter at both ends of the negative pressure box, which can be a manually adjustable screw rod lifter. The position height of the negative pressure box 2 can be finely adjusted to adapt to material pallet legs 6 of different thicknesses.

[0024] A workbench 5 longitudinally slidable is arranged on the top of the negative pressure box 2. Longitudinally extending guide rails 15 are arranged on both sides of the negative pressure box 2. A second sliding block 14 corresponding to the guide rails 15 is arranged on the bottom of the workbench 5 to guide the sliding of the workbench 5. A telescopic driving cylinder 10 driving the longitudinal movement of the workbench 5 is arranged at the end of the guide rail 15. The telescopic driving cylinder 10 can be controlled in extension and retraction through PLC to realize the longitudinal movement of the workbench 5, thereby improving the automation level and work efficiency. The gap between the bottom surface of the workbench 5 and the top surface of the negative pressure box 2 is small, which reduces the problem of air leakage. A sealing ring can also be arranged on the top of the negative pressure box 2 to further reduce the problem of air leakage without affecting the movement of the workbench 5.

[0025] The material pallet leg 6 can be placed on the workbench 5. The material pallet leg 6 is fixed by installing a tooling on the workbench 5, so that the material pallet leg 6 moves with the workbench 5. As shown in Figure 4 , dust suction holes 26 communicating with the negative pressure box 2 are arranged on the workbench 5 at intervals. The dust suction holes 26 can suck the particulate matter generated in the polishing process into the negative pressure box 2, thereby avoiding the problem of pollution of the surrounding environment.

[0026] AsFigure 2 As shown, a vacuum pump 17 is installed on the negative pressure box 2. The air inlet of the vacuum pump 17 is equipped with a filter 20 that communicates with the negative pressure box 2. The vacuum pump 17 is turned on to evacuate the negative pressure box 2. A drawer 25 is installed at the bottom of the negative pressure box 2. Particles entering the negative pressure box 2 fall into the drawer 25. After the vacuum pump 17 is turned off, the drawer 25 can be opened for cleaning.

[0027] The bracket 19 is mounted on the base 1 and located behind the negative pressure box 2. A slide rail 7, positioned horizontally above the worktable 5, is mounted on the front of the bracket 19 and can be secured with bolts, ensuring structural stability. Slide seats 12 are spaced apart on the slide rail 7. The first lifting drive mechanism 11 is vertically mounted on the slide seats 12 and adjusts laterally with the slide seats 12, improving adaptability to areas on the material tray legs 6 that require focused grinding.

[0028] The sanding belt 4 is rotatably mounted on the support 19, with its bottom passing below the first lifting drive mechanism 11. In this embodiment, the support 19 is equipped with a protective cover 3 corresponding to the sanding belt 4, which covers the upper part of the sanding belt 4, exposing the bottom. A pipe 27 is provided between the negative pressure box 2 and the protective cover 3, which can suck particulate matter in the protective cover 3 into the negative pressure box 2, reducing environmental pollution.

[0029] Several longitudinally extending rollers 18 are provided in the bracket 19 to support the rotation of the sanding belt 4. A motor 21 is provided on the base 1 or the bracket 19 to drive one of the rollers 18 to rotate, thereby realizing the rotation of the sanding belt 4. Figure 3 As shown, the bracket 19 is provided with a longitudinally extending rotating shaft 24. A lever 23 extending obliquely upward is provided on one side of the rotating shaft 24. A counterweight 9 is provided at the top of the lever 23. A swing arm 28 is provided radially on the rotating shaft. A tensioning wheel 8 extending longitudinally into the sanding belt 4 is provided at the end of the swing arm 28. The counterweight 9 drives the swing arm 28 to flip upward through the lever 23, keeping the tensioning wheel 8 in an upward state, thereby achieving automatic tensioning of the sanding belt 4 without adjustment.

[0030] A roller or pressure block 16 is provided at the bottom of the first lifting drive mechanism 11. In this embodiment, the pressure block 16 is made of nylon or smooth steel, resulting in low frictional resistance. The first lifting drive mechanism 11 is made of a cylinder or hydraulic cylinder, which can be controlled by a PLC to extend and retract, driving the roller or pressure block 16 to move downward, increasing the local friction between the sanding belt 4 and the material tray support leg 6, and focusing on grinding burrs or other defects on the material tray support leg 6.

[0031] like Figure 1As shown, the slide rail 7 is provided with a sliding groove 13, the sliding groove 13 is provided with a first sliding block corresponding to the sliding seat, the sliding seat 12 is provided with a screw connected with the first sliding block, the transverse adjustment and fixing of the sliding seat 12 are facilitated, the position of the first lifting driving mechanism 11 is changed, and the adaptability to burrs or other defect positions on the legs of different models of material pallets 6 is improved.

[0032] In conclusion, the automatic polishing mechanism for the legs of the material pallets can automatically polish the legs of the material pallets, improves the polishing efficiency and safety, has good adaptability to the thickness of the legs of the material pallets, improves the adaptability to burrs or other defect positions on the legs of the material pallets, and reduces the problem of particulate matter polluting the environment in the polishing process.
