Description

Technical Field

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

[0002] Marble is a type of metamorphic rock, named after the abundant production of this rock in Dali County, Yunnan Province, China. It is formed by carbonate rock through regional metamorphism or contact metamorphism. Marble processing generally requires grinding, and the grinding process of marble will produce dust and other substances that are harmful to the health of processing personnel. Although the existing marble grinding equipment can reduce the harm of dust to the environment and personnel to a certain extent, it cannot be cleaned and replaced in time after collection, and replacement requires shutdown, which reduces processing efficiency and increases processing costs.

[0003] After searching, the Chinese patent document (authorization announcement number CN109079630A) discloses an efficient marble grinding device, including a bracket, a workbench and a sliding sleeve. The lower end of the bracket is provided with a workbench, and the upper part of the workbench is provided with a sliding sleeve. The sliding sleeve is provided with a screw rod, and the left end of the screw rod is connected to a servo motor. The lower end of the sliding sleeve is symmetrically provided with a hydraulic rod. When the device of the present invention is practical, the marble to be polished is placed on the upper end of the rotating base, and the reduction motor is started, and the active bevel gear rotates, driving the driven bevel gear to rotate, so that the support rod rotates and the rotating base rotates, and the marble and the grinding head move relative to each other. This design reduces the grinding time, thereby improving the grinding efficiency; when the rotating base rotates, the ball rotates to support the rotating base, so that the rotating base rotates smoothly, keeps the surface of the marble flat, and avoids the uneven grinding surface; the exhaust fan is started to draw the floating dust generated by the grinding into the dust collecting tank, reduce the floating dust from being scattered into the air, thereby reducing the pollution of the working environment. The device reduces the dust pollution to a certain extent, but it cannot be cleaned and replaced in time after collection, and the machine needs to be stopped when replaced, which reduces the processing efficiency and increases the processing cost.

The cleaning box collects dust and sewage generated by grinding to prevent leakage. Motors 2 and 3 in the grinding box cooperate to drive the grinding disc to perform full-plane grinding through a spiral rod. Eight telescopic rods cooperate. When grinding, the telescopic rods judge through a position sensor to retract the telescopic rods close to the grinding disc and clamp the marble away from the grinding disc, thereby avoiding grinding dead corners at the clamping position during grinding and allowing comprehensive uniform flatness grinding. The marble is cleaned and cooled during grinding, and the sewage generated after cleaning enters the water inlet pipe through the sewage inlets around the grinding platform until it enters the horizontal rotating barrel. The outer periphery of the horizontal rotating barrel is provided with fine holes and a filter net. When motor 1 is turned on, the horizontal rotating barrel is driven to rotate, and the filtered water is thrown out and falls to the bottom of the water tank for sedimentation. The filtered water can be recycled. BRIEF DESCRIPTION OF THE DRAWINGS
