Description

Technical Field

[0001] The utility model relates to the technical field of tempered glass, in particular to a glass tempering front side grinding device. Background Art

[0002] When tempered glass is cut before tempering, some very fine cracks will be left on the side. Although it is not easy to see with the naked eye, if it is sent to the tempering furnace for tempering without treatment, it will cause edge collapse and cracking. During the heating and cooling process of the glass, the crack defects on the edge of the glass will cause the furnace to explode under the influence of several or uneven stresses, causing great losses to the equipment and even casualties. There are some fine glass slags around the un-edged glass, which are difficult to see with the naked eye. These glass slags will fall on the rollers due to swinging or cooling wind during the operation of the tempering furnace, and stick to the surface of the glass, causing pitting on the finished tempered glass produced by tempering. This will also cause damage to the rollers of the glass tempering furnace. In severe cases, the furnace needs to be stopped for treatment, which will affect the entire production progress. To this end, we propose a side grinding device before glass tempering. Utility Model Content
