Description

Technical Field

[0001] The utility model relates to the technical field of building materials, and particularly relates to a burr grinding machine for building materials. Background Art

[0002] Building materials are collectively referred to as materials used in civil engineering and construction engineering, and can be divided into structural materials, decorative materials and certain special materials. Structural materials include wood, bamboo, stone, cement, concrete, metal, bricks, tiles, ceramics, glass, engineering plastics, composite materials, etc. Usually, when using metal plates, there are certain burrs around the metal plates, so it is usually necessary to grind the metal plates.

[0003] For example, in a Chinese patent with the publication number CN211760349U, a burr grinding machine is proposed. In this patent, a pressure sensor and a controller cooperate to press down the pressing block within the pressure range that the plate can withstand. Memory sponges are bonded to the surfaces of the pressing block and the clamping seat to protect the plate, and the plate can be fixed in a non-damaged state. The pressure sensor measures the pressure value of the pressing block pressing down on the plate and transmits it to the controller. The controller controls the pressure value generated when the hydraulic cylinder drives the pressing block to press down not to exceed the set maximum pressure value that the plate can withstand, so that the plate is pressed within the bearing range. The memory sponge evenly distributes the surface pressure and adapts to the surface shape of the external pressure through stress relaxation, can gently maintain the shape of the plate and has resilience, and can protect the plate during the pressing process. However, in this solution, when the above device grinds the plate, the plate will be placed on the clamping seat and then ground by the grinding wheel. Since there may be burrs around some plates, when one side of the plate is ground, the staff needs to manually lift the plate, then move the plate out of the inside of the fixing frame, adjust the position, and then place the plate on the clamping seat again for grinding. Therefore, the staff needs to move and grind the plate multiple times. Summary of the Utility Model
