[0002] At present, as an important means of transportation in modern buildings, the safety and aesthetics of elevators are attracting more and more attention. In the elevator manufacturing process, the processing quality of the door panels is directly related to the overall quality and user experience of the elevator. During the processing of elevator door panels, the surface needs to be polished and cleaned to remove burrs, oil stains and other impurities to ensure the flatness and smoothness of the door panels.
[0003] However, the existing simple handheld grinding equipment only plays a simple grinding role. During the grinding process, a large amount of debris will fly, thus affecting the surrounding environment. The workers inhaling the debris can easily affect their health. However, after long-term use of the grinding equipment equipped with dust removal function, the debris will block the exhaust port in large quantities, thereby affecting the ventilation and dust removal effects and reducing the working efficiency of the device.
[0004] In view of this, we propose a surface grinding and cleaning device for elevator door panels. Utility Model Content

[0020] Reference Figure 1-Figure 3 The embodiment of the utility model provides a surface grinding and cleaning device for elevator door panels, including a grinding shell 1, a connecting frame 2 is fixedly connected to one side of the outer wall of the grinding shell 1, and one end of the connecting frame 2 is rotatably connected to a mounting frame 3 through a thread, a grinding disc 6 is provided at the lower part of the interior of the grinding shell 1, a rotating rod 8 is fixedly connected to the upper end surface of the grinding disc 6, and a first bevel gear 9 is fixedly connected to the outer wall of the rotating rod 8, a tight grid cylinder 12 is provided inside the connecting frame 2, a grid plate 14 and a protective net 15 are respectively fixedly connected at both ends inside the mounting frame 3, a rotating block 16 is provided inside the mounting frame 3, and a plurality of fan blades 17 are fixedly connected to the outer wall of the rotating block 16, a card block 18 is rotatably inserted inside the grid plate 14, and the card block 18 is fixedly connected to the rotating block 16, and the rotating block 16 is rotatably connected to the protective net 15, and the tight grid One end of the cylinder 12 is fixedly connected to the grid plate 14, and an extension rod 19 is provided inside the tight grid cylinder 12. One end of the extension rod 19 is fixedly connected to an insert block 21, and the insert block 21 extends into the inside of the card block 18. The other end of the extension rod 19 is fixedly connected to a second bevel gear 22, and the second bevel gear 22 is meshed with the first bevel gear 9. The rotation of the extension rod 19 drives the insert block 21 and the card block 18 to rotate synchronously. The rotation of the card block 18 drives the rotating block 16 and the fan blades 17 on the protective net 15 to rotate synchronously. The rotation of the fan blades 17 plays a role in exhausting air. The fine debris polished by the grinding disc 6 passes through the sealing ring 10 and the baffle 11 through the wind flow and enters the tight grid cylinder 12. The tight grid cylinder 12 collects these fine debris, which is convenient for later cleaning and can also prevent debris from flying and polluting the surrounding environment.
[0021] Reference Figure 1 and Figure 2 The upper end surface of the grinding shell 1 is fixedly connected with a motor 4, and the output end of the motor 4 extends into the interior of the grinding shell 1 and is fixedly connected to the rotating rod 8. The bottom of the grinding shell 1 is fixedly connected with a soft bristle strip 5. The interior of the grinding shell 1 is fixedly connected with a fixed frame 7. The rotating rod 8 penetrates the fixed frame 7 and is rotatably connected with the fixed frame 7. The soft bristle strip 5 on the grinding shell 1 can block debris and prevent it from flying.
[0022] Reference Figure 2 A sealing ring 10 is fixedly connected to one side of the inner wall of the connecting frame 2, and a baffle 11 is fixedly connected to the lower part of the sealing ring 10. The extension rod 19 passes through the baffle 11 and is rotatably connected to the baffle 11. The baffle 11 limits the extension rod 19 on the one hand, and blocks the debris inside the tight grid tube 12 on the other hand to prevent the debris from entering the grinding shell 1.
[0023] Reference Figure 2 and Figure 3 The outer wall of the tight mesh cylinder 12 is symmetrically fixedly connected with the clamping strip 13, and the outer wall of one end of the extension rod 19 is fixedly connected with a pair of brush strips 20, and the brush strip 20 is L-shaped, and the outer walls of the brush strip 20 are in contact with the inner wall of the tight mesh cylinder 12 and the mesh plate 14 respectively. During the ventilation process, debris will be adsorbed on the inner wall of the tight mesh cylinder 12 and the mesh plate 14, and the rotation of the extension rod 19 drives the brush strip 20 to rotate. The rotation of the brush strip 20 will move the debris on the inner wall of the tight mesh cylinder 12 and the mesh plate 14 to prevent the holes on the tight mesh cylinder 12 and the mesh plate 14 from being blocked, affecting the ventilation and dust collection effect, thereby improving the cleaning effect and work efficiency.
[0024] Working principle: When grinding the elevator door panel, the staff holds the handle and starts the motor 4. The motor 4 drives the output end to rotate, and the rotation of the output end drives the rotating rod 8 to rotate. The rotation of the rotating rod 8 drives the grinding disc 6 and the first bevel gear 9 to rotate synchronously. The grinding disc 6 rotates to grind the elevator door panel. Fine debris will be generated during the grinding process. The soft hair strips 5 on the grinding shell 1 can block the debris and prevent the debris from flying;
[0025] The rotation of the first bevel gear 9 drives the meshed second bevel gear 22 to rotate, and the rotation of the second bevel gear 22 drives the extension rod 19 to rotate. Since the plug block 21 on the extension rod 19 is located in the block 18 on the grid plate 14, the rotation of the extension rod 19 drives the plug block 21 and the block 18 to rotate synchronously. The rotation of the block 18 drives the rotating block 16 and the fan blades 17 on the protective net 15 to rotate synchronously. The rotation of the fan blades 17 plays a role in exhausting air, and small debris passes through the sealing ring 10 and the baffle 11 through the wind flow and enters the tight grid cylinder 12. The debris will be adsorbed on the inner wall of the tight grid cylinder 12 and the grid plate 14. The extension rod 19 will drive a pair of brush strips 20 on the outer wall to rotate while rotating. The rotation of the brush strips 20 will move the debris on the inner wall of the tight grid cylinder 12 and the grid plate 14 to prevent the holes on the tight grid cylinder 12 and the grid plate 14 from being blocked, thereby affecting the ventilation and dust collection effect;
[0026] When the elevator door panel is polished, rotate and remove the installation frame 3. The movement of the installation frame 3 drives the tight grid tube 12 to move. The clamping strip 13 on the tight grid tube 12 is separated from the limit frame on the inner wall of the connection frame 2, and the plug block 21 is separated from the clamping block 18 on the grid plate 14. The staff cleans up the debris on the inner wall of the tight grid tube 12, and finally the tight grid tube 12 is inserted back into the connection frame 2. One end of the tight grid tube 12 is against the sealing ring 10, and the installation frame 3 is rotated and installed to the connection frame 2.
