Description

Technical Field

[0001] The utility model relates to a stone grinding device, in particular to a water sprinkling device for stone grinding and a stone grinding device. Background Art

[0002] Natural building stones mainly include marble, granite and bluestone. These stones need to go through cutting, grinding, polishing and other processes before they become finished slabs. Stone grinding and polishing are generally carried out on stone grinding equipment. Depending on the grinding surface, the grinding wheel used is also different. When a large area of ​​flat surface needs to be polished, a crown grinding wheel is generally used, and the grinding surface is the annular plane on the grinding wheel; when a chamfer or a narrow area needs to be polished, an edge grinding wheel is generally used, and the grinding surface is the circular side of the grinding wheel. Since water needs to be continuously added to the grinding area during the stone grinding process, the rotating grinding wheel will cause the waste liquid mixed with debris to splash around. The rotation axis of the crown grinding wheel is usually vertical, so the waste liquid splash area is horizontal and circular, and the rotation axis of the edge grinding wheel is usually horizontal, so the waste liquid splash area is mainly vertical fan-shaped. Since the rotation speed of the grinding wheel is extremely fast, if the splashing waste liquid is not shielded, the waste liquid splash area is very large, which will cause serious pollution to the production site. Therefore, most stone grinding equipment is equipped with a water retaining structure. However, in order to avoid friction between the water retaining structure and the moving stone, a certain gap will still be formed between the two. Splashing sewage and water mist can easily fly out of the gap, causing certain pollution. Summary of the invention

[0003] The utility model provides a water sprinkling device for stone grinding, which solves the problem in the prior art that sewage splashes during the stone grinding process, causing pollution to equipment and sites.

[0004] The above technical problems of the utility model are mainly solved by the following technical solutions: a water spraying device for stone grinding, characterized in that it includes a vertically arranged guide rod, a sliding sleeve slidably assembled on the guide rod, a locking device arranged on the sliding sleeve, and a water spraying assembly fixed on the sliding sleeve, wherein the water spraying assembly includes a mounting seat fixed relative to the sliding sleeve, a cover plate arranged at the bottom of the mounting seat, and a brush arranged on the bottom surface of the cover plate, the top view profile of the mounting seat is annular or C-shaped, a plurality of water spraying holes are arranged on the cover plate, and a water supply pipeline and a water supply interface connected to the water spraying holes are arranged on the mounting seat. When the rotating axis of the grinding wheel is vertical, the mounting seat needs to adopt an annular structure, so that the brush can be arranged around the crown grinding wheel; when the rotating axis of the grinding wheel is horizontal, the mounting seat can adopt a C-shaped structure to ensure that the rotating side of the grinding wheel is blocked by the brush.

[0005] The utility model is fixed on the stone grinding equipment through a guide rod, and the height of the water shower assembly is controlled by adjusting the height of the sliding sleeve on the guide rod, and the sliding sleeve is fixed by a locking device. The water shower assembly has the effect of replenishing water to the grinding wheel and preventing sewage from splashing. Specifically, the water supply interface on the water shower assembly is connected to the water pipe, and the water can be finally discharged from the water shower hole on the cover plate through the water supply pipeline, so as to wet the stone and the grinding wheel in the grinding area. At the same time, the brushes on the bottom surface of the cover plate are distributed on the path of waste liquid splashing and can directly contact the stone surface, so the protection effect is excellent. When the brush is worn, it can be compensated by lowering the height of the water shower assembly.

[0006] Furthermore, the mounting seat is also provided with a water baffle. When the rotation axis of the grinding wheel is vertical, the water baffle on the mounting seat is generally a rubber sheet with a circular ring structure, the water baffle is higher than the grinding wheel and partially covers the grinding wheel; when the rotation axis of the grinding wheel is horizontal, the water baffle on the mounting seat is generally in an "Ω" shape, and is entirely wrapped outside the annular side wall of the grinding wheel.

[0007] The utility model also provides a stone grinding device, including a machine body, a transmission component, a grinding component and a water spraying device, characterized in that the water spraying device is the above-mentioned stone grinding water spraying device. Since the above-mentioned stone grinding water spraying device has the above-mentioned technical effects, the stone grinding device having the water spraying device also has the same technical effects.

[0008] Therefore, compared with the prior art, the utility model has the following characteristics: 1. The water supply interface on the water shower assembly is connected to the water pipe, and the water can be finally discharged from the water shower hole on the cover plate through the water supply pipeline, so as to moisten the stone and grinding wheel in the grinding area. The brushes on the bottom surface of the cover plate are distributed on the path of waste liquid splashing and can directly contact the surface of the stone, so the protective effect is excellent. Therefore, the water shower assembly has the effect of replenishing water to the grinding wheel and preventing sewage from splashing; 2. A water baffle is also provided on the mounting seat to make up for the deficiency that the brush cannot block water in the upper area of ​​the stone. BRIEF DESCRIPTION OF THE DRAWINGS
