Description

A stone surface polishing device Technical Field

[0001] This utility model relates to the field of stone surface polishing technology, and specifically to a stone surface polishing device. Background Technology

[0002] Stone, as a high-end building decoration material, is widely used in interior and exterior decoration design, curtain wall decoration, and public facility construction. Currently, the most common types of stone on the market are natural stone and artificial stone. Natural stone is further divided into slate and granite based on its physical and chemical properties. Artificial stone is divided into terrazzo and synthetic stone based on its manufacturing process. With the development of architectural design, stone has long been one of the important raw materials for construction, decoration, roads, and bridges.

[0003] Chinese utility model patent publication number "CN 212145719 U" discloses a stone processing surface grinding device. This device places stone slabs inside a dustproof housing for grinding, preventing excessive stone powder dispersion and reducing dust pollution, while also protecting the health of operators. By incorporating an electric lifting rod into the grinding assembly and fixing a drive motor with a grinding disc to the electric lifting rod via a motor mounting plate, the distance between the grinding disc and the stone slab can be easily adjusted during grinding. This allows for grinding of stone slabs of different thicknesses, and the grinding thickness can also be adjusted by changing the distance between the grinding disc and the stone slab.

[0004] The aforementioned device grinds the stone by driving an electric lifting rod and a grinding disc. However, there are gaps between the grinding discs, which cannot be adjusted by the device, affecting the quality of stone grinding. Furthermore, the device draws out dusty air by using a fan, but the dustproof housing has inlet and outlet ports, making it impossible to seal off the dusty air. The escaped dusty air can easily pollute the working environment. Summary of the Invention
