The application relates to the technical field of edge
grinding machine equipment, and discloses a
vertical edge grinding machine for marble manufacturing, which comprises a platform, a vertical plate is welded to the upper surface of the platform, a protective cover is welded to the side surface of the vertical plate, an edge
grinding wheel is connected to the inside of the protective cover through a rotating shaft, an edge grinding sand belt is arranged on the surface of the edge
grinding wheel, a silent motor is connected to the end of the rotating shaft through a shaft
coupling, and the inside of the edge
grinding wheel is hollow. In the application, the hollow edge
grinding wheel forms an air flow channel with the air
pipe through the
air exchange hole, the cooling air flow conveyed by the silent
turbine fan acts on the surface of the edge grinding sand belt (the base belt surface in contact with the wheel body) through the annular groove, and the
nozzle of the cooling
water pipe sprays, so that the double cooling of 'internal cooling +
water cooling' is formed, the heat generated by the friction of the edge grinding sand belt can be quickly taken away, the sand belt is prevented from being aged or abraded due to high temperature, and the service life of the sand belt is prolonged.
