It should be noted that the upper and lower roller groups 2 are aligned in the longitudinal direction, so that when the span adjustment mechanism adjusts the span between the roller assemblies, the tensioning force can be guaranteed and the diamond wire 3 is more evenly stressed.

[0024] A lifting mechanism 9 is provided below the diamond wire 3, and is used for carrying and moving the cutting material 12, so that the cutting material 12 can be cut close to the diamond wire 3; wherein, the lifting mechanism 9 comprises a table 10 and a cylinder 11, and the cylinder 11 is installed on the bottom side of the table 10, and the output end of the cylinder 11 passes through the table 10 and abuts against the cutting material 12. When cutting, the cutting material 12 is lifted by the cylinder 11 to make it close to the diamond wire 3 for cutting.

[0025] Preferably, the span adjustment mechanism comprises a second drive motor 13, a screw rod 14, a nut block 15 and a connecting frame 16, wherein the screw rod 14 is vertically arranged between the two roller assemblies and is connected to the second drive motor 13 in transmission; two nut blocks 15 are connected to the screw rod 14, the middle part of the connecting frame 16 is hinged to the nut block 15, and the two ends are respectively hinged to the roller assemblies on both sides, and a screw structure is formed between the nut block 15 and the screw rod 14, wherein the second drive motor 13 is installed on the lower side of the frame 1, with the output end facing upward, and is connected to the screw rod 14 in transmission through a coupling. When the second motor drives the screw rod 14 to rotate, the nut block 15 is limited by the rotation of the connecting frame 16, so that when the nut block 15 moves longitudinally on the screw rod 14, the connecting frame 16 can drive the roller assemblies on both sides to move closer or farther, so that the spacing between the two groups of roller assemblies can be adjusted, and then the span of the diamond wire 3 can be adjusted, so that the tension of the diamond wire 3 can be adjusted.

[0026] Furthermore, a limit block 17 is provided at the top end of the screw rod 14 . The limit block 17 can play a limiting role, thereby preventing the nut block 15 at the high end from falling off the screw rod 14 .

[0027] Preferably, a slide rail 18 is transversely arranged on the frame 1, and the roller assembly is slidably connected to the slide rail 18. Furthermore, the roller assembly is provided with a sliding seat 7, the mounting seat 4 and the first drive motor 6 are mounted on the sliding seat 7, and the sliding seat 7 is slidably connected to the slide rail 18, so that the roller assembly can move left and right on the frame 1 to adjust the position.

Among them, the connecting frame 16 is hingedly arranged with the slide seat 7. When the second drive motor 13 drives the screw 14 to rotate and controls the nut block 15 to move up and down, it can eventually be converted into the left and right movement adjustment of the roller 5, thereby adjusting the tension of the diamond.

[0028] Preferably, the connecting frame 16 includes two groups of articulated rod groups 19, and the two groups of articulated rod groups 19 are hingedly arranged on both sides of the nut block 15, one end of the articulated rod group 19 is hingedly arranged with the nut block 15, and the other end is hingedly arranged with the roller assemblies on both sides. Among them, in this embodiment, the two sides of the nut block 15 protrude to form a rotating shaft, and the two groups of articulated rod groups 19 are connected to the rotating shaft. There are many ways of articulation, which will not be described here. Furthermore, a bearing seat 8 is provided on the sliding seat 7, and the other end of the articulated rod group 19 is connected to the sliding seat 7 through the bearing in the bearing seat 8, so that when the middle part of the articulated rod group 19 moves with the nut block 15, the two ends can drive the sliding seats 7 on both sides to move. The two groups of articulated rod groups 19 provide a more stable connection relationship to ensure stability during adjustment. It should be noted that each group of roller groups 2 corresponds to two slide rails 18, and the sliding seats 7 corresponding to the two slide rails 18 are respectively arranged under the mounting seat 4 and the first drive motor 6, and the screw 14 passes between the two slide rails 18, and the mounting seat 4 and the first drive motor 6 are fixedly connected.

[0029] Preferably, the roller 5 is provided with a plurality of wire grooves 20, and the wire grooves 20 are used to place and connect the diamond wires 3. By providing a plurality of wire grooves 20, a plurality of diamond wires 3 can be placed, thereby achieving a multi-wire cutting effect and better cutting efficiency.

[0030] When the tension of the diamond wire 3 becomes smaller during processing, the second drive motor 13 can be started to drive the screw 14 to rotate, and the connecting frame 16 can be driven by the nut block 15 to transmit the movement to the slider seat, and finally drive the roller assembly to move left and right, change the span, and then change the tension of the diamond wire 3, so that the wire network is evenly stressed.

[0031] When cutting stones of different sizes, the optimal cutting distance can be achieved by changing the span, or by replacing diamond wires of different lengths 3, effectively controlling the wire tension, improving cutting efficiency, ensuring cutting results, and reducing cutting waste.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
