[0036] Reference Figures 1 to 6, this embodiment provides a stone wire drawing machine, including a frame, the frame is provided with a conveying device for conveying stone, and the frame is also provided with a pressing mechanism, the pressing mechanism is used to press the stone onto the conveying device;

[0037] The conveying device comprises a plurality of conveying rollers 1 arranged in parallel and spaced apart from each other, and the conveying rollers 1 are rotatably connected to the frame;

[0038] A main shaft 2 is arranged on the frame below the clamping mechanism, and a plurality of saw blades are arranged on the outer periphery of the main shaft 2, and the main shaft 2 is located between two adjacent conveying rollers 1; specifically, the saw blade installed on the main shaft 2 in this embodiment is a customized saw blade with a diameter of 105 mm, which is lighter than the traditional saw blade with a diameter of 195 mm.

[0039] It also includes a driving mechanism, which includes a motor and a reducer. The output end of the reducer is connected to the conveying roller 1 and the main shaft 2. Specifically, the main shaft 2 and the conveying roller 1 are connected to the driving mechanism through belt drive or chain drive.

[0040] The traditional wire drawing machine uses a chain pull-belt method to drag the stone on the iron plate. When the stone has an arc during the transmission process, the stone will be subjected to uneven force, causing the stone to collapse and fall off, which increases the damage rate of the stone during the wire drawing process and reduces the work efficiency. In this embodiment, a plurality of parallel and spaced conveying rollers 1 are used to replace the traditional chain pull-belt method, which greatly improves the stability of the transmission, effectively avoids the uneven force on the stone during the transportation process, thereby causing the stone to collapse and fall off, reduces the damage rate during the material processing process, and improves the quality and efficiency of production.

[0041] In the embodiment of the present application, the clamping mechanism includes a mounting frame 3, and a plurality of clamping rollers 301 are rotatably provided at the bottom of the mounting frame 3. Specifically, the clamping rollers 301 are linearly distributed along the length and width directions of the device.

[0042] In the embodiment of the present application, the outer circumferential surface of the pressing roller 301 is provided with stripes evenly distributed along the axial direction, so as to increase the friction force while pressing, which helps to transmit power more effectively and enhance the guiding effect on the conveying stone.

[0043] In the embodiment of the present application, the mounting frame 3 includes a plurality of connecting posts 302 connected to the frame and a mounting plate 303 connected to the plurality of connecting posts 302;

[0044] The pressure roller 301 is installed on the mounting plate 303 through the guide frame 304. The guide frame 304 and the mounting plate 303 slide together in the vertical direction, and an elastic member 305 is provided between the guide frame 304 and the mounting plate 303. The elastic member 305 applies elastic force to the guide frame 304 so that the pressure roller 301 presses the stone.

[0045] In the embodiment of the present application, the guide frame 304 includes a connecting plate 3041 rotatably connected to both ends of the pressing roller 301, and a connecting rod 3042 is fixedly connected to the connecting plate 3041, and the connecting rod 3042 is slidably connected to the mounting plate 303;

[0046] The elastic member 305 is sleeved on the outer circumference of the connecting rod 3042 , and the elastic member 305 is compressed and abutted between the connecting plate 3041 and the mounting plate 303 .

[0047] Specifically, the elastic member 305 is a compression spring. When the device is not working, the elastic member 305 is in a relaxed state. When the device starts to draw the stone, the pressure roller 301 contacts the stone, and the connecting rod 3042 moves upward. At this time, the elastic member 305 is in a compressed state, which exerts downward pressure on the stone, making the stone more stably transmitted during the drawing process.

[0048] In the embodiment of the present application, the connecting column 302 includes a fixed portion 3021 connected to the frame, and a lifting portion 3023 that is telescopically matched with the fixed portion 3021, and a sleeve 3022 is provided on the outer cover of the lifting portion 3023. Specifically, the lifting portion 3023 and the sleeve 3022 are rotatably connected in the circumferential direction and relatively fixed in the axial direction, and the lifting portion 3023 is threadedly connected to the fixed portion 3021. In this embodiment, the sleeve 3022 is connected to the mounting plate 303.

[0049] Specifically, since the lifting part 3023 is threadedly connected to the fixed part 3021, the operator can adjust the height of the lifting part 3023 by rotating the lifting part 3023 forward or reversely. When the lifting part 3023 rotates up or down, the sleeve 3022 maintains its position unchanged in the circumferential direction and rises and falls synchronously with the lifting part 3023 in the axial direction, thereby adjusting the height of the mounting plate 303, so that the device can change the installation height of the clamping mechanism according to the thickness of the processed stone, and is suitable for wire drawing processing of stones of various thicknesses.

[0050] In the embodiment of the present application, a lifting mechanism 5 is provided on the frame, the lifting mechanism 5 is provided with a limiting portion 501 , and both ends of the main shaft 2 are rotatably connected to the limiting portion 501 .

[0051] Specifically, the lifting mechanism 5 can be a screw lifting mechanism, a hydraulic lifting mechanism, an electric push rod lifting mechanism, a pneumatic lifting mechanism, etc. In this embodiment, the lifting mechanism 5 is preferably a screw lifting mechanism, and a lifting part is provided at each end of the main shaft 2, and the lifting parts are connected by a connecting rod 502, so that the lifting heights of the two ends of the main shaft 2 are consistent.

[0052] Specifically, the connecting rod 502 is rotatably matched with the frame, and a turntable 503 is coaxially fixedly connected to one end of the connecting rod 502, and the operator can rotate the connecting rod 502 through the turntable 503. The lifting part includes a screw rod 504, which is threadedly connected with the limiting part 501, and the limiting part 501 is slidably matched with the frame in the vertical direction, and the lower part of the screw rod 504 is transmission-connected with the connecting rod 502 to convert the rotation of the connecting rod 502 into the rotation of the screw rod 504. In this embodiment, the two ends of the connecting rod 502 are connected to the corresponding lower part of the screw rod 504 through bevel gear transmission. When the connecting rod 502 rotates, the screw rod 504 rotates, and the limiting part 501 is slidably matched with the frame, so that the limiting part 501 is lifted and lowered, thereby driving the main shaft 2 to lift and lower. The use of this lifting mechanism 5 makes a series of cumbersome operations of lifting and lowering the main shaft 2 during disassembly simpler, and effectively improves the work efficiency.

[0053] In the embodiment of the present application, a plurality of fixing members 4 are provided on the frame, and both ends of the conveying roller 1 are rotatably connected to the corresponding fixing members 4 . Specifically, the fixing members 4 are fixed by bolts.

[0054] In the embodiment of the present application, the conveying roller 1 includes a driving roller 101 and a plurality of driven rollers, and the driving roller 101 is connected to the driving mechanism by transmission, and specifically, the driving roller 101 is connected to the belt at the output end of the reducer in the driving mechanism. In this embodiment, the driven roller is connected to the driving roller 101 by transmission, and specifically, one end of the driving roller 101 and the driven roller is provided with a sprocket, and the power is transmitted to the driven roller through the driving roller 101 through the meshing of the chain with the corresponding sprocket.

[0055] In the embodiment of the present application, the outer periphery of part of the conveying roller 1 is covered with a conveyor belt 6, and a plurality of tensioning rollers 7 for tensioning the conveyor belt 6 are rotatably arranged at the lower part of the frame; specifically, the surfaces of the conveying roller 1 and the tensioning roller 7 have a certain friction force to make the transmission more stable.

[0056] The conveyor belt 6 includes a connecting portion 601 at the bottom and a first conveying portion 602 and a second conveying portion 603 at the top. The first conveying portion 602 and the second conveying portion 603 are arranged at intervals, and the main shaft 2 is located between the first conveying portion 602 and the second conveying portion 603 .

[0057] Specifically, the outer surface of the conveyor belt 6 is provided with a deeper anti-skid texture, which increases the friction between the conveyor belt and the stone, so as to prevent the stone from slipping during the wire drawing process.

[0058] Working principle: The operator puts the stone to be processed from one end of the equipment, places it on the conveyor roller 1, and the front end of the stone is placed on the conveyor belt 6. Since the conveyor roller 1 is in a rotating state when working, it drives the conveyor belt 6 to move. At this time, the contact between the stone and the conveyor roller 1 is rolling contact, and the stone is in a relatively static state with the conveyor belt 6. When the stone is transported to the bottom of the clamping mechanism, the clamping mechanism exerts downward pressure on the stone, so that the stone is in a stable state during the processing. Then, the stone reaches the middle position between the first conveying part 602 and the second conveying part 603, and the saw blade on the main shaft 2 performs wire drawing on the lower surface of the stone. As the conveyor belt 6 continues to move forward, the processed stone is output from the other end.
