[0002] Stone is widely used in the industry of building decoration, and natural stone for building decoration mainly includes granite and marble. The volume and thickness of the stone just mined are large, and it is necessary to cut the stone into smaller thickness of stone plate. At present, the multi-wire cutting device is commonly used. The existing multi-wire cutting device on the market mostly winds the diamond wire on four main guide wheels, and the diamond wire forms two cutting planes. However, since the four main guide wheels are fixed and immovable, when the height of the stone exceeds the distance between the upper and lower main guide wheels, the upper diamond wire will cut the stone twice. Since the two upper and lower diamond wire planes are not completely parallel, waste products are easily produced. Therefore, the existing multi-wire cutting device limits the size and height of the processed material. SUMMARY

[0023] In combination Figure 1 As shown, in the embodiment, the structure of the rack 1 is not limited, which is used to install the cutting mechanism and the adjusting mechanism. The workbench 2 is formed below the rack 1, and the workbench 2 is provided with a jacking device 5 to jack up the stone on the workbench 2 to the cutting wire net for cutting, that is, the jacking device 5 is used to jack up the stone placed on the workbench 2, so as to cooperate with the cutting wire net for cutting. Of course, in other embodiments, the cutting feed can also be realized by moving the cutting wire net. The jacking device 5 here can adopt the mode of hydraulic jacking or motor jacking, or other structures that can realize lifting.

[0024] In combination Figures 1 to 5 As shown, the first main guide wheel 302 and the second main guide wheel 303 are arranged on the opposite sides of the rack 1, the first main guide wheel 302 and the second main guide wheel 303 have a certain length, and the grooves are arranged on each main guide wheel 3, and the cutting wires are suitable for winding in the grooves. The first main guide wheel 302 or the second main guide wheel 303 is connected with a driving mechanism to drive the first main guide wheel 302 and the second main guide wheel 303 to rotate. In the embodiment, the cutting wire can adopt diamond wire 301, the diamond wire 301 is wound between the first main guide wheel 302 and the second main guide wheel 303 to form cutting wire nets on the upper side and the lower side of the main guide wheel 3. When the driving motor 304 rotates, each diamond wire 301 rotates at high speed to realize the cutting effect.

[0025] In combination Figures 1 to 5As shown, the inner side of the first main guide wheel 302 and the second main guide wheel 303 is provided with the first line pressing wheel 401 and the second line pressing wheel 402, and the first line pressing wheel 401 and the second line pressing wheel 402 are arranged in parallel with the first main guide wheel 302 and the second main guide wheel 303. A plurality of roller wheels 403 are arranged on the first line pressing wheel 401 and the second line pressing wheel 402, and the roller wheels 403 are provided with line grooves parallel to the grooves. Here, the first line pressing wheel 401 and the second line pressing wheel 402 are arranged on the upper part of the upper cutting wire net, and the bottom of the line groove is flush with the bottom of the groove of the main guide wheel 3, so that the upper cutting wire net can be pressed to be coplanar and parallel with the lower cutting wire net. Meanwhile, the line grooves and the grooves are staggered, so that the upper cutting wire net can be pressed to be between the lower cutting wire net when the diamond wire 301 rotates at high speed. Both groups of cutting wire nets can achieve cutting effect, and can act on different positions of the stone to improve the cutting efficiency in a limited space. In this embodiment, the line grooves and the grooves are arranged at equal distances, so that the thickness of the cut stone plate is the same. Of course, in other embodiments, the staggered distance between the line grooves and the grooves can be adjusted to be unequal, so that different thicknesses of stone plates can be cut in the same cutting wire net according to needs. Therefore, in another embodiment, a distance adjusting mechanism can be arranged on the adjusting mechanism 4 to adjust the distance between adjacent roller wheels 403. The distance adjusting mechanism can be adjusted manually when the equipment is stopped, or other existing structures can be used to adjust the distance between the roller wheels 403, and the specific structure is not limited here.

[0026] In this embodiment, the roller wheels 403 are installed on the shaft of the first line pressing wheel 401 and the second line pressing wheel 402 through bearings 404, and are provided with shaft sleeves to limit their movement, so that the roller wheels 403 can rotate with the diamond wire 301 during work to reduce friction damage.

[0027] Through the embodiment scheme, when the diamond wire 301 is wound from the lower side of the main guide wheel 3 to the upper side, the line pitch and direction of the cutting wire net are changed through the roller wheels 403 on the line pressing wheel, so that the cutting wire net is parallel and coplanar with the cutting wire net on the lower side of the main guide wheel 3 and is staggered with each other. The roller wheels 403 on the line pressing wheel are fixed through the bearings 404, and the roller wheels 403 and the bearings 404 are limited by the shaft sleeves. When the main guide wheel 3 drives the diamond wire 301 to move, the roller wheels 403 will rotate, so as to avoid damage to the roller wheels 403 caused by friction as much as possible. During work, the jacking device 5 on the workbench 2 lifts the stone, and the high-speed moving diamond wire 301 cuts the stone. The two diamond wires 301 are in the same plane and parallel to each other, which avoids secondary cutting and does not limit the height of stone processing, thereby improving the applicability of the cutting equipment.

[0028] It should be understood that the above are only preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments, and any technical solutions falling within the concept of the present application shall fall within the protection scope of the present application.
