Technical Field

[0001] The utility model relates to the technical field of wooden handicraft processing, and more specifically to a dust removal device for polishing wooden handicrafts. Background Art

[0002] During the processing of wooden handicrafts, semi-finished products need to be polished. During the polishing process, in order to reduce the harm caused by dust to operators, a dust removal device will be used to extract the dust to achieve the purpose of protecting the operators.

[0003] Most of the current dust removal devices use an exhaust method to suck air mixed with grinding dust into the interior of a dust removal box, and then filter the dust in the air through the dust filter screen inside the dust removal box, and discharge the filtered clean air out of the dust removal box. However, since the grinding debris of wood products is light in weight and small in size, under the action of the suction force, after being intercepted by the dust filter screen, it will not fall down along the surface of the dust filter screen, but will adhere to the surface of the dust filter screen and cause the dust filter screen to be blocked, thereby affecting the dust removal effect of the entire dust removal device. In order to ensure the use effect of the dust removal device, it is necessary to manually clean the dust filter screen frequently, which has the disadvantages of being inconvenient to use and cumbersome to operate.
