[0025] Working principle: For this type of steel nail grinding device, first, the operator places the support 1 for keeping the device stable during weight balancing on one side of the grinding table 12. The connecting seat 3 is fixed to the fixing plate 2 of the support 1 by riveting. Then, according to the size of the steel nails to be ground, the relative gap between the sandpaper belt 11 sleeved on the sleeve 10 of the support plate 8 and the grinding table 12 is adjusted. The support plate 8 is riveted to the mounting seat 7. The angles between the mounting seat 7, the second rotating arm 6, the rotating cylinder 5, the first rotating arm 4, and the connecting seat 3 can be adjusted by tightening or loosening the connecting bolts. When the bolts are tightened, the angle is fixed. When the bolts are loosened, rotation adjustment can be performed to facilitate the adjustment of the gap between the sandpaper belt 11 on the support plate 8 and the grinding table 12, so as to quickly adapt to the grinding operations of steel nails of different specifications. Subsequently, the operator places the steel nails to be ground in the feeding groove 13 on the grinding table 12. A feeding wheel 16 is rotatably disposed in the wheel groove 14 inside the feeding groove 13 through a bearing. The feeding wheel 16 rotates on the inner wall of one side of the feeding groove 13 driven by the output shaft of the second motor 15 to push the steel nails, causing the steel nails to move towards the gap between the grinding table 12 and the sandpaper belt 11. The output shaft of the first motor 9 drives the sleeve 10 and the sandpaper belt 11 to rotate for automatic feeding and grinding operations. Finally, when the sandpaper belt 11 is worn after a period of grinding operations, the operator can remove it from the groove 17 on the rotating cylinder 5 through the limiting belt 18 for quick disassembly, replacement, and to maintain the high-efficiency and stability of the grinding operations of this device.
