Description

Stone trimming device

The present invention relates to a fine processing apparatus for stone for processing a non-slip protrusion on an upper surface of a stone for use as a step stone.

In general, various materials are used for interior and exterior materials for construction to suit the function and aesthetics of the interior and exterior spaces of the building. These interior and exterior materials serve to block rain and wind, cold weather, sunlight, fire, heat and noise, and wood, synthetic resin, paper, and stone are mainly used as materials.

Among the materials of interior and exterior materials used for conventional construction, stone is used in various ways as a durable and eco-friendly material. However, the existing stone materials could not satisfy the needs of consumers who demand various colors and textures by using the textures and colors obtained from nature as they are.

However, in the case of marble, in order to process the surface of the collected natural stone, a worker uses a chisel and a hammer to polish the surface by striking. However, the grinding process takes great effort and takes a long time to obtain the desired stone material, thereby increasing the processing cost. The disadvantage was that it was very expensive.

In the prior art for fine-tuning the surface of such a stone, Utility Model Application No. 20-1974-0000566 (name of the design: fine-refining hammer of stone surface) and registered patent No. 10-0915142 (title of invention: stone) A surface roughening surface group) is provided.

This prior art stone grinding hammer forms a handle so that the operator grips the handle and then the fine grinding hammer strikes the marble surface, and the operator grips and fixes it for a long time by the vibrating fine hammer and its weight. There is a problem that it is difficult to do it, and there is a problem that it is inconvenient to move the heavy fine-tuning hammer.

In addition, the prior art stone surface fine-refining surface machine provides power to form uniform and stable irregularities on the surface of the stone while rotating naturally according to the direction of movement when it touches the surface of the stone through a fine-refining device that rotates at high speed. It can be widely used as interior and exterior materials for construction by fine trimming, and by installing a fine trimming device on an automatic processing machine, the left and right movement, up and down movement, and movement speed, movement and displacement of the fine trimming device can be freely controlled, giving the operator dust. It is characterized in that it can be automatically processed so as not to be damaged by excessive and pollutants.

However, in this prior art, since the fine trimming device of the automatic feeder is installed in a pair on the left and right sides of the front, the processing of the upper surface of a long and narrow stone can be performed in one operation, but the upper surface of a long and wide stone can be processed in one operation. The processing cannot be carried out at once, so it has to be processed repeatedly. Also, the conveying speed of the stone conveyed along the conveyor and the left and right movement speed of the fine-finishing device cannot be properly matched, so the conveyor is stopped in the automatic feeder area to prevent the stone material from being processed. There is a problem in that the workability is deteriorated as the machining operation is repeatedly performed after stopping the transfer of the machine.
