[0028] Please see Figure 1-6 The technical solution provided by this utility model is as follows:

[0029] Example 1:

[0030] In this embodiment, an elevator door headboard grinding device with dust prevention function includes a grinding device body 1, a lifting processing seat 11 for loading the headboard body 13 is fixedly installed inside the grinding device body 1, a limit mechanism 12 is installed on the lifting processing seat 11, and a grinding assembly 14 is provided inside the grinding device body 1 above the headboard body 13, and two dust removal components 2 are provided on the grinding assembly 14.

[0031] The grinding assembly 14 includes a grinding cylinder 141 fixed to the inner wall of the grinding device body 1, a motor body 142 mounted on the grinding cylinder 141, a grinding wheel 143 connected to the output end of the motor body 142 via a rotating shaft, and the grinding wheel 143 rotatably connected to the bottom end of the grinding cylinder 141. A dust collection cover 144 is fixed on the outer wall of the grinding cylinder 141.

[0032] Each dust collection assembly 2 includes a dust collection cylinder 21 fixed on both sides of the dust collection hood 144. A drive shaft 23 is rotatably connected to the inner wall of the dust collection cylinder 21. A central bevel gear ring 22 is fixed on the arc-shaped outer wall of the drive shaft. A side bevel gear 231 that meshes with the central bevel gear ring 22 is fixedly provided at one end of the drive shaft 23. A fan body 24 is fixedly provided on the arc-shaped outer wall of the drive shaft 23. A slip ring 25 is slidably connected to the inner wall of the dust collection cylinder 21. A filter bag assembly 26 is rotatably connected to the slip ring 25. A return spring 251 is fixedly provided between the slip ring 25 and the inner wall of the dust collection cylinder 21. A transmission assembly 27 is provided between one end of the fan body 24 and the filter bag assembly 26. A collection assembly 3 is provided on the inner wall of each dust collection cylinder 21.

[0033] The dust collection hood 144 has air inlets on both sides that are connected to the two dust collection cylinders 21. The bottom of the dust collection hood 144 has an air inlet that is annular. The two dust collection cylinders 21 are symmetrically arranged about the grinding cylinder 141. The end of the dust collection cylinder 21 away from the rotating shaft has an air outlet.

[0034] Each dust collection cylinder 21 has a side sliding groove on its inner wall that matches the slip ring 25. The side sliding groove is cylindrical. One end of the return spring 251 is fixedly connected to the slip ring 25, and the other end of the return spring 251 is fixedly connected to the inner wall of the side sliding groove.

[0035] The dust filter bag assembly 26 includes a bag frame 261 rotatably connected to a slip ring 25, a rubber ring that contacts the bag frame 261 is fixedly provided on the arc-shaped inner wall of a return spring 251, and a bag body 262 is fixedly provided on the inner side of the dust filter bag assembly 26.

[0036] The transmission assembly 27 includes a fixing ring 271 fixed to one end of the fan body 24, and a plurality of arc-shaped guide strips 273 fixedly provided on the end of the bag frame 261 near the fan body 24. A plurality of pushing posts 272 are fixed to the end of the fixing ring 271, and each pushing post 272 is in contact with each arc-shaped guide strip 273.

[0037] Each collection component 3 includes a magnetic absorption collection ring 31 that is snapped onto a slip ring 25. The inner wall of the slip ring 25 is provided with a plug hole that matches the magnetic absorption collection ring 31. Each dust collection cylinder 21 has a plug 32 inserted into its outer wall. The plug 32 extends from the outer wall of the dust collection cylinder 21 to the inner wall of the dust collection cylinder 21.

[0038] The dust collection cylinder 21 has a plug groove that matches the plug 32, and the plug groove is arc-shaped. The plug groove matches the magnetic absorption collection ring 31. The bottom of the lifting processing seat 11 is equipped with an electric telescopic rod, and the bottom of the electric telescopic rod is fixedly connected to the inner wall of the grinding device body 1.

[0039] When polishing the main body 13 of the door panel, the motor body 142 can be started and the polishing wheel 143 connected to its output end via the rotating shaft can be rotated to one side. At this time, the polishing wheel 143 can polish the top of the main body 13 of the door panel and generate a large amount of iron powder dust. At the same time, it drives the central bevel gear ring 22 fixed on the outer wall of the rotating shaft to rotate. Under the meshing engagement of the central bevel gear ring 22 and the two side bevel gears 231, the two drive shafts 23 can be driven to rotate around the positions connected to the two dust collection cylinders 21, thereby causing the wind fixed on the outer wall of the drive shaft 23 to rotate. When the fan body 24 rotates, the rotation of the two fan bodies 24 creates a negative pressure inside the two dust collection cylinders 21, allowing the dust generated during grinding to enter the dust collection cylinder 21 through the air inlet of the dust collection hood 144. At this time, the filter bag body 262 can filter the dust in the air carrying the dust, and then the filtered air can be discharged through the air outlet on the dust collection cylinder 21. While the drive shaft 23 rotates, it can drive the fixing ring 271 fixed at the end of the fan body 24 to rotate, and drive the multiple push columns 272 fixed at the end of the fixing ring 271 to rotate, such as... Figure 6 At this time, the pushing column 272 can contact the lower part of the arc-shaped guide strip 273 near the fixing ring 271. The rotation of the fixing ring 271 can drive the bag keel 261 fixedly connected to the arc-shaped guide strip 273 to rotate, and at the same time drive the bag body 262 on the bag keel 261 to rotate, so that the dust can be evenly distributed on the bag body 262, and can prevent the surface of the bag body 262 from being blocked.

[0040] When dust needs to be removed from the bag body 262, the motor body 142 can be started to rotate the shaft to the other side. Simultaneously, with the cooperation of the dust removal assembly 2, the pushing column 272 can slide along the surface of the arc-shaped guide strip 273, pushing the bag frame 261, which is fixedly connected to multiple arc-shaped guide strips 273, to slide to one side. This also causes the slip ring 25, which is rotatably connected to the bag frame 261, to slide to one side, while simultaneously compressing the return spring 251. When the pushing column 272 slides to the arc-shaped guide strip 273 near the fixed... When the iron powder is below one side of ring 271, the bag body 262 can vibrate under the elastic force of the return spring 251, causing the dust on the surface of the bag body 262 to fall to one side of the magnetic absorption collecting ring 31. At this time, the magnetic absorption collecting ring 31 can adsorb and collect the fallen iron powder. When it is necessary to remove the magnetic absorption collecting ring 31, the motor body 142 can be started to drive the rotating shaft to rotate to the other side, so that the magnetic absorption collecting ring 31 is located below the plug 32. At this time, the magnetic absorption collecting ring 31 can be removed by pulling out the plug 32.

[0041] Working principle: When in use, first, place the door headboard body 13 on the lifting processing seat 11. Then, with the cooperation of the limiting mechanism 12, the lifting processing seat 11 can be limited and clamped. Then, start the electric telescopic rod to drive the door headboard body 13 on the lifting processing seat 11 to rise, so that the top of the door headboard body 13 contacts the bottom of the grinding wheel 143.

[0042] Secondly, by starting the motor body 142, the grinding wheel 143 connected to its output end via the rotating shaft rotates to one side. At this time, the grinding wheel 143 can grind the top of the door panel body 13, generating a large amount of iron powder dust. Simultaneously, it drives the central bevel gear ring 22 fixed on the outer wall of the rotating shaft to rotate. Under the meshing engagement of the central bevel gear ring 22 and the two side bevel gears 231, the two drive shafts 23 can be driven to rotate around the positions connected to the two dust collection cylinders 21, thereby causing the fan body 24 fixed on the outer wall of the drive shaft 23 to rotate. When the two fan bodies 24 rotate, a negative pressure is generated inside the two dust collection cylinders 21, allowing the dust generated during grinding to enter the dust collection cylinders 21 through the air inlet of the dust collection hood 144. At this time, the filter bag body 262 can filter the dust in the air carrying the dust, and the filtered air can then be discharged through the air outlet on the dust collection cylinder 21. Simultaneously, the rotation of the drive shaft 23 drives the fixed ring 271 fixed at the end of the fan body 24 to rotate, and also drives the multiple pushing columns 272 fixed at the end of the fixed ring 271 to rotate. Figure 6 At this time, the pushing column 272 can contact the lower part of the arc-shaped guide strip 273 near the fixing ring 271. The rotation of the fixing ring 271 can drive the bag keel 261 fixedly connected to the arc-shaped guide strip 273 to rotate, and at the same time drive the bag body 262 on the bag keel 261 to rotate, so that the dust can be evenly distributed on the bag body 262.

[0043] Finally, when removing dust from the bag body 262, the motor body 142 can be started to rotate the shaft to the other side. Simultaneously, with the cooperation of the dust removal assembly 2, the pushing column 272 can slide along the surface of the arc-shaped guide strip 273, pushing the bag frame 261, which is fixedly connected to multiple arc-shaped guide strips 273, to slide to one side. This also causes the slip ring 25, which is rotatably connected to the bag frame 261, to slide to one side, while simultaneously compressing the return spring 251. When the pushing column 272 slides to the arc-shaped guide strip 273 near the fixed... When the fixed ring 271 is below one side, the bag body 262 can vibrate under the elastic force of the return spring 251, causing the dust on the surface of the bag body 262 to fall to one side of the magnetic absorption collecting ring 31. At this time, the magnetic absorption collecting ring 31 can adsorb and collect the fallen iron powder. When it is necessary to remove the magnetic absorption collecting ring 31, the motor body 142 can be started to drive the rotating shaft to rotate to the other side, so that the magnetic absorption collecting ring 31 is located below the plug 32. At this time, the magnetic absorption collecting ring 31 can be removed by pulling out the plug 32.
