Description

Technical Field

[0001] This utility model belongs to the field of granite processing technology, and in particular relates to a vertical grinding device for granite. Background Technology

[0002] Granite, as a natural stone, is widely used in building decoration and flooring due to its high hardness, wear resistance, and unique texture. Surface polishing is an important step in granite processing. Through mechanical grinding and polishing processes, the stone surface can achieve a smooth and flat surface or a special textured effect, enhancing both aesthetics and practicality.

[0003] Comparing with Chinese Patent No. CN216542286U, a grinding device for granite processing is disclosed, including side plates, a base plate, and a telescopic rotating frame. The side plates are disposed at opposite ends of the base plate, and the telescopic rotating frame is disposed on the base plate. The side plates and the base plate are provided with processing structures, which include: a top groove, a side cavity, a first motor, a first screw, a lifting block, a clamping plate, a pulley, and an output part. The top groove is opened on the side plate, the lifting block is threadedly connected to opposite ends of the first screw, the clamping plate is disposed on the side surface of the lifting block, the pulley is disposed on the clamping plate, and the output part is disposed on the base plate. By lying flat, the stone column is fixed in the middle and rotated, and the stone column is moved left and right on both sides for polishing. This allows for rapid and uniform surface polishing with high safety.

[0004] However, when the granite column is held flat and polished on the side using the aforementioned patent, it is difficult to ensure the stability of the granite column under the combined effects of gravity and polishing vibration, which seriously affects the processing accuracy. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide a vertical grinding device for granite to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vertical granite grinding device includes a frame assembly for supporting and fixing a downward-pressing granite column, and a support assembly at the bottom center of the frame assembly for supporting the rotation and surface changing of the granite column. Two execution components are symmetrically arranged on both sides of the frame assembly for vertically lifting and rotating to grind the surface of the granite column. The frame assembly includes a support platform, a cantilever frame behind the support platform, a telescopic cylinder mounted at the top of the cantilever frame, and a downward-pressing plate rotatably mounted at the bottom telescopic end of the telescopic cylinder. The support assembly includes a support tray, a drive shaft fixedly mounted at the bottom of the support tray, and a drive mechanism for providing rotational power at the bottom of the drive shaft. The execution components include a lifting mechanism for adjusting the height, and a rotary grinding mechanism for telescopic feeding and rotating grinding is located in the middle of the lifting mechanism.

[0008] Furthermore: a bearing seat is fixedly installed in the middle of the support platform, and a motor seat is provided on the bottom surface of the support platform.

[0009] Furthermore, both the pressure plate and the support plate are circular and of the same size.

[0010] Furthermore: the drive mechanism includes a second gear mounted on the bottom end of the transmission shaft, a first gear meshing on one side of the second gear, and the first gear being keyed to the output end of the first motor.

[0011] Furthermore, the surface of the tray is covered with an anti-slip mat.

[0012] Furthermore: the lifting mechanism includes a fixed frame, a lead screw is installed in the middle of the fixed frame, a second motor is provided at the top of the lead screw, and a lifting frame is installed in the middle of the lead screw; the rotary grinding mechanism includes an electric push rod installed on the lifting frame, a movable frame is installed at the telescopic end of the electric push rod, a rotary motor is installed on the movable frame, and a grinding disc is installed at the output end of the rotary motor.

[0013] Furthermore, the diameter of the grinding disc is larger than the diameter of the support tray.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] 1. The support plate and the lower pressure plate are matched in size and have anti-slip pads attached to their surfaces. They clamp the granite columns vertically, enhancing the stability of the stone and preventing slippage during rotation or grinding, thus ensuring uniform surface treatment. At the same time, the frame components (support platform, cantilever frame) and bearing seats work together to ensure the stability of the drive shaft and the lower pressure plate, preventing offset caused by grinding vibration and ensuring processing accuracy.

[0016] 2. The bearing tray is driven to rotate by a gear transmission system, and the telescopic cylinder is pressed down to fix it, so as to achieve precise face changing of granite columns and avoid the safety risks and time loss of traditional manual turning.

[0017] 3. The symmetrical grinding discs on both sides rotate and grind simultaneously. Combined with the horizontal feed of the electric push rod and the vertical movement driven by the screw, it can achieve full surface coverage grinding of the granite column in the vertical state, reduce manual intervention and significantly improve efficiency. The diameter of the grinding disc is larger than that of the support tray to ensure complete coverage of the side of the stone and avoid missed grinding or repeated processing.
