Dust-free wall surface grinding machine for building decoration

Abstract

The invention provides a dust-free wall surface grinding machine for building decoration and relates to the field of building decoration tools. The dust-free wall surface grinding machine for building decoration comprises a grinding mechanism and a dust removal mechanism. The grinding mechanism comprises a millstone. Abrasive paper is arranged on one side of the millstone, the millstone is provided with a first through hole, and the abrasive paper is provided with a second through hole. The dust removal mechanism comprises a first sealing part and a dust suction part. The first sealing part is of a bowl-shaped structure with an opening formed in one end. The end, with the opening, of the first sealing part is movably buckled on the side, away from the abrasive paper, of the millstone. The first sealing part is provided with a third through hole. The dust suction part communicates with the first sealing part through the third through hole. During grinding, a second sealing part is attached to a wall surface and seals the side, used for grinding, of the millstone, and powder cannot leak. The first sealing part is buckled on the other side of the millstone and seals the other side of the millstone, and the dust is sucked by the dust suction part immediately reaching the first sealing part. The dust suction part is provided with straps, and a worker can carry the dust suction part around. The device is high in grinding efficiency and good in dust removal effect.

Description

technical field [0001] The invention mainly relates to the field of building decoration tools, in particular to a dust-free wall grinder for building decoration. Background technique [0002] Architectural decoration, especially interior decoration, the indispensable procedure is wall whitening, and the commonly used methods of whitening are brushing paint, scraping putty, etc. Due to the strong smell of paint and the short service life, it has gradually been replaced by other methods . The most commonly used method of whitening the wall in the prior art is putty scraping. Usually, after the putty is scraped on the wall, unevenness will appear on the surface, and the wall surface needs to be polished to achieve a certain smoothness. The most commonly used grinding method is to use sandpaper for manual grinding. This grinding method is inefficient, labor-intensive, and produces a lot of dust during the grinding process. Moreover, due to the small indoor environment space, th...

AI Technical Summary

Problems solved by technology

The dust-free grinding machine has a certain dust-absorbing effect, but because there is no sealing device in the grinding process, part of the dust generated by the grinding will also break away from the grinding disc and fall out, resulting in poor dust removal effect

And the device for containing the dust is fixed, it is inconvenient to move when grinding, which will affect the efficiency of grinding
