[0020] The utility model provides a technical solution: Figure 1 , Figure 2 and Figure 3 As shown, in the present embodiment, an abrasive spraying device for a polishing pad comprises a fixed base 1, an abrasive box 2 is arranged on one side of the top surface of the fixed base 1, a turntable 5 is arranged on the other side of the top surface of the fixed base 1, a driving motor 6 is installed on the inner side of the bottom of the fixed base 1, and the output end of the driving motor 6 is connected to the turntable 5, a spraying pipe 3 is installed on the top of one side of the abrasive box 2, a nozzle 4 is arranged on the bottom of one end of the spraying pipe 3, the top of the nozzle 4 is rotatably connected to the spraying pipe 3, and the nozzle 4 is at the top of the turntable 5, a feeding port is arranged on the top surface of the abrasive box 2, and a protective component is arranged on the side of the turntable 5, the protective component comprises a limiting ring groove 7 arranged on the side of the turntable 5, and a gathering ring 8 is opened on the top surface of the fixed base 1, and the limiting ring groove 7 is engaged with the gathering ring 8 The limiting ring groove 7 is connected to the outside of the turntable 5 through the gathering ring 8. The height of the limiting ring groove 7 is greater than the inner wall depth of the gathering ring 8. The opening of the limiting ring groove 7 is in the same horizontal plane as the top surface of the turntable 5. A protective ring 9 is fixed on one side of the opening of the limiting ring groove 7. The side surface of the turntable 5 is provided with a limiting groove 12 at equal angles. The internal arrangement of the limiting groove 12 is provided with a ball 11. The surface of the ball 11 is rolled and fitted with one side surface of the limiting ring groove 7, which is convenient for protecting the side of the turntable 5, so that during the operation of the spraying device, the abrasive will not spill onto the surface of the fixed base 1. At the same time, it is also convenient to collect the abrasive splashed during spraying, without the need for workers to manually clean and collect, thereby avoiding the waste of abrasive, and the practical effect is good.

[0021] like Figure 2 , Figure 3 and Figure 4As shown, a limiting assembly is provided on the top surface of the turntable 5, and the limiting assembly includes a limiting plate 10 which is equiangularly arranged at the edge of the top surface of the turntable 5, and an installation slot 13 for the bottom of the limiting plate 10 to engage is provided at an equiangular position at the edge of the top surface of the turntable 5, and a fixing column 14 is fixed inside the inner side of the installation slot 13, and a connecting slot 15 for the fixing column 14 to engage is provided on one side of the bottom end surface of the limiting plate 10, and an elastic ring 16 is fixed on the surface of the fixing column 14, and a connecting annular groove 17 is provided on the inner wall of the connecting slot 15, and the outer surface of the elastic ring 16 is tightly fitted with the inner surface of the connecting annular groove 17, and the cross-section of the limiting plate 10 is "L"-shaped, and the surface of the elastic ring 16 is raised, which is convenient for limiting the polishing pad and placing it on the surface of the turntable 5, so that the polishing pad will not move during the rotation of the turntable 5, which is convenient for improving the efficiency and effect of spraying abrasive on the polishing pad, and has good practicality.

[0022] The utility model provides an abrasive spraying device for a polishing pad, and the specific working principle is as follows: when the protective component is installed in the early stage of the utility model, the limiting ring groove 7 is first pushed to move toward the top surface of the fixed base 1, so that the limiting ring groove 7 can be set to the outside of the turntable 5, until the limiting ring groove 7 is limited and engaged to the inside of the collecting ring 8 on the top surface of the fixed base 1. At this time, the protective ring 9 on one side of the opening of the limiting ring groove 7 can realize the protection of the outside of the turntable 5. When the spraying device sprays abrasive on the surface of the polishing pad, the protective ring 9 can have a good protective effect, so that the abrasive will not spill onto the top surface of the fixed base 1. At the same time, the limiting ring groove 7 can collect the splashed abrasive, and there is no need for workers to clean the surface of the fixed base 1, and it also avoids the waste of abrasive. When the turntable 5 rotates, the surface of the limiting ring groove 7 will roll and fit with the surface of the ball 11 inside the limiting groove 12, which can reduce the rotation of the turntable 5. The friction force between the limiting ring groove 7 and the limiting ring groove 7 is good in practicality; when the polishing pad needs to be limited and placed on the surface of the turntable 5, the polishing pad is first pushed to move toward the top surface of the turntable 5. At this time, the edge of the bottom end surface of the polishing pad will first contact the inner bottom surface of the limiting plate 10. At this time, the polishing pad will exert pressure on the limiting plate 10, so that the limiting plate 10 will move toward the inside of the mounting groove 13 through the fixing column 14. At the same time, the surface of the elastic ring 16 will lose connection with the inner surface of the connecting ring groove 17 until the bottom end surface of the limiting plate 10 is fitted and connected with the inner bottom surface of the mounting groove 13. At this time, the bottom end surface of the polishing pad will also be fitted and connected with the top surface of the turntable 5. At this time, the multiple limiting plates 10 at the edge of the turntable 5 can realize the limiting of the polishing pad, so that the polishing pad will not move when the spraying device is spraying abrasive, which is convenient for improving the efficiency and effect of spraying abrasive on the polishing pad, and has a good practical effect.
