[0020] The following further elaborates on the present application in conjunction with the attached Figures 1-4 drawings for a more detailed description.

[0021] First embodiment

[0022] Refer to Figures 1-4, a grinding device for billboard processing, including a support frame 1. One end of the support frame 1 is welded with a filter bin 2 on the outside. A blower 3 is installed on one side inside the filter bin 2. A filter screen box 4 is slidably embedded on the other side inside the filter bin 2. The air outlet end of the blower 3 is connected to one end of the filter screen box 4. A number of holes are opened on the outside of the filter bin 2. A motor bin 5 is arranged on the outside of the other end of the support frame 1. One end of the motor bin 5 is welded with a downward pressure chute 19 on the outside. A connecting slide bar 20 is slidably embedded inside the downward pressure chute 19. The bottom end of the motor bin 5 is welded with a support cover 6 through a bracket. In order to enable the support frame 1 to press down the grinding mechanism, a rubber ring gasket 7 is fixed to the bottom end of the support cover 6 by bolts. In order to limit the grinding debris, a number of communication grooves 8 are penetrated and opened at the top end of the support cover 6. A first closed cover 9 is fixed to the outside surface of the top end of the support cover 6 through bolts at the top end of the communication groove 8. One side of the top end of the first closed cover 9 is connected with a connecting pipe 10. The air outlet end of the connecting pipe 10 is connected to the air inlet end of the blower 3. A grinding motor 17 is installed inside the motor bin 5. The driving end of the grinding motor 17 is rotatably connected with a collar 11. A limiting ring 18 is welded on the outside of the driving end of the grinding motor 17 at the top end of the collar 11. In order to prevent the driving end of the grinding motor 17 from sliding inside the collar 11 and thus unable to drive the collar 11 to move downward, a number of rebound grooves 12 are opened on the inner side of the middle of the support cover 6. A return spring 13 is installed at the bottom end of each of the number of rebound grooves 12. In order to enable the grinding mechanism to reset, a connecting slider 14 is slidably embedded at the top of the return spring 13 inside each of the number of rebound grooves 12. One end of each of the number of connecting sliders 14 is welded to the outside of the collar 11. The driving end of the grinding motor 17 is connected with a grinding disc 15 through a coupler at the bottom end of the collar 11. One end of the filter bin 2 is fixed with a second closed cover 16 through bolts. One end of the connecting slide bar 20 is welded to the outside of one end of the support frame 1. The other end of the connecting slide bar 20 is fixedly connected to the grinding motor 17 through bolts.

[0023] Working principle: First, the operator fixes the billboard to be ground. Then, the operator places the grinding mechanism on the top surface of the billboard and places the rubber ring gasket 7 at the position to be ground. Then, the operator presses down the support frame 1. At this time, the support frame 1 will press down the motor bin 5 connected to it, and the motor bin 5 will press down the connecting slide bar 20 welded to it, and the connecting slide bar 20 will press down the grinding motor 17 connected to it. At this time, the grinding motor 17 will press down the collar 11 connected to its driving end. At this time, the collar 11 will press down a number of connecting sliders 14 welded to its outside, and the connecting sliders 14 will slide down inside the rebound grooves 12 opened on the inner side of the middle of the support cover 6;

[0024] The collar 11 will press down its bottom end and slide down through the grinding disc 15 rotatably connected to the transmission shaft of the inner grinding motor 17. At this time, the grinding disc 15 will contact the outer surface of the top end of the bulletin board. Then the operator starts the grinding motor 17, and the grinding motor 17 will drive the grinding disc 15 connected to its transmission end to rotate, so as to achieve grinding. During this period, the debris generated by grinding will be limited by the rubber ring gasket 7. Then the operator starts the fan 3. At this time, the fan 3 will suck air into the connecting pipe 10 connected to its air inlet end. The connecting pipe 10 will suck air into the first closed cover 9 fixed to the top end of the support cover 6 by bolts. The first closed cover 9 will suck air through a number of communication grooves 8 opened at the top end of the support cover 6, collect the debris inside the support cover 6 and the rubber ring gasket 7, discharge it through the air outlet end of the fan 3, and filter it by the filter box 4. Such a design can prevent the grinding debris from splashing, thus protecting the safety of the operator.

[0025] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
