Description

Technical Field

[0001] The utility model belongs to the technical field of marble polishing, in particular to a marble polishing device. Background Art

[0002] Marble is an important building material. It is easy to process because of its high compressive strength and good physical and chemical properties.

[0003] The existing marble polishing device needs to fix the marble during use, but the existing fixing method is single. In the process of processing marbles of different sizes, the fixed limit device needs to be replaced, which reduces the use efficiency.

[0004] For example, (authorization announcement number CN221313771U) an artificial marble polishing device is provided with a conduit, a nozzle, a water tank and a water filling cover. During use, the water filling cover is first opened to add water into the water tank. During polishing, the water pump can be started to extract the water inside the water tank, and the water is transported to the nozzle through the conduit and sprayed out. The spraying effect of the nozzle is used to make the water form atomization and fall around the polishing device, which can effectively reduce the dust flying around during polishing, thereby having the function of preventing dust from spreading. This device has the problem that it cannot effectively fix marbles of different sizes, reducing the use efficiency. Utility Model Content
