Description

Technical Field

[0001] The utility model relates to the technical field of glass processing machinery, in particular to a multi-angle edge grinding machine. Background Art

[0002] In the process of glass production, in order to meet various usage needs, the glass is first divided into small pieces. In order to facilitate the next processing, the glass cut into small pieces often needs to be edged. At present, most of them use edge grinding machines for edge grinding. Its working principle is that the cut glass is driven by a glass conveyor belt and enters the edge grinding machine. When the glass moves to the edge grinding station, the grinding wheel grinds the edge of the glass.

[0003] When the existing edge grinding machine is working, it is necessary to apply a certain pressure to the glass relative to the grinding wheel, and the glass is ground during the moving process. Improper pressure application will cause excessive or uneven resistance to the glass movement, which will cause uneven glass edge grinding or deflection of the glass, causing the grinding wheel to break the glass and cause waste. In addition, after the existing edge grinding machine is working, a large amount of dust will adhere to the surface of the glass after the edge grinding is completed. The existing grinder only has the function of grinding and is unable to remove dust from the glass after grinding, thereby reducing the efficiency of glass production and processing.
