Description

Technical Field

[0001] The invention relates to a two-roller diamond wire cutting machine for stone with a wire wheel. Background Art

[0002] Traditionally, the cutting tools used to process rough stone into slabs include saw blades, saw belts, and beaded wire saws. These tools typically involve welding alloy diamond segments to saw blades or steel belts, or stringing these segments together to form a wire saw. Traditional stone processing machines, such as bridge-type combination stone saws, marble frame saws, granite sand saws, multi-strand wire saws, and band saw splitters, use these cutting tools to process rough stone. Because alloy diamond segments are bulky and require attachment to a metal substrate, traditional cutting tools require a certain thickness to ensure proper cutting and cannot be infinitely thinned. Consequently, kerfs of 3-10mm are formed when cutting the stone, resulting in waste and pollution. This also contributes to the drawbacks of traditional stone processing equipment, such as large kerfs, high noise levels, a large footprint, high energy consumption, and significant pollution.

[0003] To this end, in the Chinese invention patent application publication number CN 109866338 A, entitled "A New Stone Cutting Winding Device and Stone Cutting Saw Machine", a stone cutting saw machine is disclosed, including a new stone cutting winding device, a stone transfer vehicle, and a cutting transfer bracket. The new stone cutting winding device is movably mounted on the cutting transfer bracket, or / and the stone transfer vehicle is movably arranged below the new stone cutting winding device; a channel is formed on the cutting transfer bracket for the stone transfer vehicle to move through, and the channel is located below the new stone cutting winding device; the stone transfer vehicle is equipped with multiple groups of vertically retractable support rod assemblies arranged along the moving direction of the stone transfer vehicle. When the support rod assemblies approach the new stone cutting winding device, they move downward to allow the stone transfer vehicle to pass through the channel below the new stone cutting winding device, and at the same time, the stone on it is cut by the wire net on the new stone cutting winding device. Among them, the new stone cutting winding device includes a mounting frame, a wire guide wheel, a first cutting guide wheel and a second cutting guide wheel. The two ends of the wire guide wheel, the first cutting guide wheel and the second cutting guide wheel are respectively rotatably connected to the mounting frame. The wire guide wheel, the first cutting guide wheel and the second cutting guide wheel are parallel and spaced apart. The first cutting guide wheel is arranged between the wire guide wheel and the second cutting guide wheel. The first cutting guide wheel and the second cutting guide wheel are respectively provided with a plurality of positioning parts for winding the diamond cutting wire to form a spaced parallel wire network.

[0004] During use, it was discovered that the diamond wire of this type of sawing machine is set at an acute angle relative to the axis of the wire guide wheel. This requires high precision in the placement of the diamond wire on the wire guide wheel, making debugging more difficult. If the angle of the diamond wire at a certain position is not properly arranged, the diamond wire will axially cut the wire guide wheel during the sawing process, increasing the running resistance of the wire guide wheel and even cutting the wire guide wheel, causing wear. In addition, the support rod assembly needs to be precisely controlled during the sawing process to ensure that the support rod assembly rises and falls in an orderly manner, which increases the difficulty of control and affects the stability of the processing.
