Description

Technical Field

[0001] The utility model relates to the technical field of stone processing equipment, in particular to a closed-loop independent tensioning and detection mechanism. Background Art

[0002] In the stone processing industry, stone is a natural material formed by magma gushing out and invading the earth's crust to form lava, which is affected by high temperature and high pressure, crustal movement, climate weathering, and other complex physical environments. It contains silicon dioxide, calcium carbonate, iron, magnesium, etc. The material purity is not high, and the content of components in different parts of the stone is different, showing that the hardness is uneven in different places. Wire saw equipment is generally equipped with a unified tensioning system. This unified tensioning system only has a tensioning effect on the wires close to the edge of the stone, and has no tensioning effect on the wires in the middle of the stone. In the multi-wire cutting of stone, the hardness inside the stone is uneven, the cutting resistance of each wire is different, the sawing progress of each wire is different, and the tension of each wire is also different. The unified tensioning system of the existing stone cutting multi-wire saw equipment cannot ensure that the tension of each wire is the same, and cannot meet the precise control requirements for the tension of each wire in the multi-wire saw equipment, which limits the accuracy, cutting efficiency and personalized adjustment of stone processing. A closed-loop independent tensioning and detection mechanism is needed to solve this problem. Utility Model Content
