[0002] The glass positioning and edge grinding machine for door and window production is a special equipment used for accurate positioning and edge grinding of glass during the door and window manufacturing process. It can ensure the processing accuracy and quality of glass and improve the assembly accuracy and aesthetics of doors and windows. The glass positioning and edge grinding machine for door and window production usually adopts a computer control system, which can automatically position and edge grind according to the glass size and processing requirements. It contains main components such as positioning device, edge grinding device, transmission device, etc. The positioning device can accurately position the glass in the edge grinding position to ensure the accuracy and consistency of edge grinding. The edge grinding device can grind the edge of the glass to eliminate dimensional errors and surface defects and provide a flat and smooth edge. The glass positioning and edge grinding machine for door and window production is efficient, precise and stable, which can greatly improve the production efficiency and product quality of door and window manufacturing. It is widely used in door and window manufacturing, architectural decoration, furniture manufacturing and other industries.

[0003] When grinding the glass, most existing edge grinding machines place the glass on a conveying wheel and use the conveying wheel to convey the glass for grinding instead of positioning the glass. However, some customized doors and windows have single-sided glass with a large area, and general grinders cannot adapt to their size. At the same time, their thickness is thicker than other glasses. If grinding is performed by conveying the glass, the conveying device needs greater power, and the grinding wheel also needs greater power. At this time, the glass and the grinding wheel will vibrate when they collide with each other, resulting in poor grinding effect. Utility Model Content
