[0017] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0018] Please see Figures 1-5 This application provides a protective device, including a base 2 and a shielding component 3.

[0019] The base 2 has U-shaped guide grooves 21 on its front and sides. The shielding assembly 3 includes guide blocks 31, transparent strips 32, flexible belts 33, and handles 34. Multiple guide blocks 31 are slidably disposed inside the guide grooves 21, and the flexible belts 33 connect the multiple guide blocks 31, with gaps between adjacent guide blocks 31. The bottom end of the transparent strip 32 is fixedly connected to the front of the guide blocks 31, and two handles 34 are respectively installed on the front of the transparent strip 32 at the left and right ends.

[0020] When it is necessary to use multiple transparent strips 32 in the shielding assembly 3 to shield the sparks and debris generated during grinding by the grinding wheel, simply pull the handle 34 on the front of one side of the transparent strip 32. The handle 34 drives the guide block 31 to slide inside the guide groove 21 through the transparent strip 32. Multiple flexible belts 33 pull multiple guide blocks 31 to slide inside the guide groove 21, that is, multiple transparent strips 32 slide together to the front of the grinding wheel to shield the debris that flies during grinding, providing good protection. After use, pull the handle 34 on one side, and the transparent strip 32 and flexible belts 33 work together to move multiple guide blocks 31 inside the guide groove 21 to the side of the base 2, which facilitates loading and unloading.

[0021] Specifically, the base 2 also includes a limiting block 22, which is fixed to the end of the guide groove 21 on the outside of the base 2. The limiting block 22 limits and prevents the guide block 31 from sliding out of the guide groove 21.

[0022] Furthermore, the guide block 31 has a relief groove 35 on its back, and a flexible strip 33 passes through the relief groove 35 and connects to the guide block 31. This arrangement prevents friction between the flexible strip 33 and the inner wall of the guide groove 21. The shielding assembly 3 also includes a fixing bolt 36, which connects the transparent strip 32 and the guide block 31.

[0023] This application also provides a grinding machine including the aforementioned protective device and a grinding machine body 1, with a stand 2 installed in the grinding operation area of ​​the grinding machine body 1. The grinding machine also includes a lighting assembly 4, which is installed on the side of the grinding machine body 1 and projects illumination light into the grinding operation area. The lighting assembly 4 includes a frame 41, a folding frame 42, and a lamp 43. The frame 41 is fixed to the grinding machine body 1, and the folding frame 42 connects the lamp 43 to the frame 41. The lighting assembly 4 also includes a damping shaft 44, which is rotatably mounted to the frame 41 and connected to the end of the folding frame 42 away from the lamp 43.

[0024] The lighting assembly 4 is installed on the side of the grinding machine body 1, and can project light onto the grinding area through the lighting lamp 43, providing good illumination during processing. The folding frame 42 can be folded to adjust the distance between the lighting lamp 43 and the workpiece being ground, and the damping shaft 44 can be used to adjust the horizontal rotation of the lighting lamp 43.

[0025] It should be noted that the specific model and specifications of the lighting lamp 43 need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts existing technology in this field, so it will not be described in detail here. The power supply and principle of the lighting lamp 43 are clear to those skilled in the art, and will not be described in detail here.

[0026] The working principle of this protective device and grinding machine is as follows: When it is necessary to use multiple transparent strips 32 in the shielding assembly 3 to shield the sparks and debris generated during grinding by the grinding wheel, simply pull the handle 34 on the front of one side of the transparent strip 32. The handle 34 drives the guide block 31 to slide inside the guide groove 21 through the transparent strip 32. Multiple flexible belts 33 pull multiple guide blocks 31 to slide inside the guide groove 21, that is, multiple transparent strips 32 slide together to the front of the grinding wheel to shield the debris flying during grinding, thus providing good protection. After use, pull the handle 34 on one side, and the transparent strip 32 and flexible belts 33 work together to move multiple guide blocks 31 inside the guide groove 21 to the side of the table 2. At this time, the shielding is removed, making it convenient for loading and unloading. The gap between adjacent guide blocks 31 is at the arc-shaped structure of the bend in the guide groove 21, which allows for turning along the guide groove 21.

[0027] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
