[0020] The conveying device 2 includes two pulleys 20 arranged at an interval, a conveyor belt 21 which is tensioned between the two pulleys 20 and can convey continuously, a support plate 22 which abuts against the back of the straight conveying section of the conveyor belt 21, and a second motor 23 which is connected through a belt transmission mechanism and drives the pulley 20 to rotate. A reducer is provided on the second motor 23. The conveyor belt 21 is arranged vertically along the width direction, and the support plate 22 abuts against the back of the straight conveying section of the conveyor belt 21.

[0021] The pressing device 3 includes a pressing wheel 30, an axle 31, an axle box 32 and a third motor 33. The axle box 32 is arranged on the frame, the axle 31 is vertically rotatably arranged on the axle box 33, the pressing wheel 30 is arranged on the axle 31, and the third motor 33 is connected to and drives the axle 31 to rotate. The pressing wheel 30 is arranged at an interval with the front side of the straight conveying section of the conveying device 2. The rotation direction of the pressing wheel 30 is opposite to the rotation direction of the conveyor belt 21. The plate-like stone on the workbench 1 can be pressed between the pressing wheel 30 and the front side of the straight conveying section and conveyed forward.

[0022] The auxiliary pressing device 5 includes an auxiliary pressing wheel 50, a swing arm 51 and a torsion spring 52. The swing arm 51 can be rotatably arranged around a vertical pivot axis. The auxiliary pressing wheel 50 is arranged at the front end of the swing arm 51. The torsion spring 52 is used to drive the swing arm 51 to swing toward the straight conveying section. The auxiliary pressing wheel 50 cooperates with the pressing wheel 30 to press the plate-like stone. The auxiliary pressing device 5 is arranged at intervals with the pressing device 3 along the straight transmission direction of the conveyor belt 21 through a base extending from the axle box 32. The auxiliary pressing wheel 50 is arranged behind the pressing wheel 30. When the stone part is out of the pressing range of the pressing wheel 30, it will be pressed again on the conveyor belt 21 by the auxiliary pressing wheel 50, so that the edge of the stone will not be lifted, and the whole cutting process will be smoother and safer.

[0023] The cutting device 4 includes a circular saw blade 40, a rotating shaft box 41, a rotating shaft 42, and a first motor 43. The rotating shaft box 41 is arranged on the frame, the rotating shaft 42 can be rotatably arranged on the rotating shaft box 41, the circular saw blade 40 is arranged on the rotating shaft 42, the first motor 43 is connected through a belt transmission mechanism and drives the rotating shaft 42 to rotate, the rotating shaft box 41 can be axially movable along the rotating shaft 42 on the frame, an adjustment mechanism is arranged between the rotating shaft box 41 and the frame, the adjustment mechanism includes a screw nut pair 410 for driving the rotating shaft box 42 to move, the rotating shaft 41 extends horizontally and is arranged vertically with the straight conveying section, the circular saw blade 40 is arranged on the rotating shaft 41 and can cut the plate-like stone pressed between the pressure wheel 30 and the front side of the straight conveying section of the conveyor belt 21.

[0024] The cutting device 4 is provided with a dustproof cooling mechanism, which is a water outlet extending to the side of the circular saw blade 40. During the cutting process, the water outlet sprays water toward the circular saw blade 40, which can not only prevent smoke and dust but also cool the heat generated by the friction between the circular saw blade 40 and the plate-like stone during the cutting process, thereby increasing the service life of the circular saw blade 40 and also speeding up the recycling of the stone after cutting.

[0025] Reference Figures 1 to 4 When the present invention is working, the first motor 43, the second motor 23 and the third motor 33 are started, the first motor 43 drives the circular saw blade 40 to rotate, the second motor 23 drives the conveyor belt 21 to rotate, and the third motor 33 drives the pressure wheel 30 to rotate. The plate-like stone to be cut thin is placed vertically on the workbench along the width direction and slowly pushed between the conveyor belt 21 and the clamping device 3. After the plate-like stone contacts the pressure wheel 30 and the conveyor belt 21, the conveyor belt 21 and the pressure wheel 30 rotate relative to each other to transport the stone forward close to the conveyor belt 21. After being cut by the cutting device 4, the cut stone is slowly transported away from the circular saw blade, the stone is recovered, and the cutting is completed.

[0026] During cutting, when part of the cut stone is transported away from the clamping device 3, the auxiliary clamping device 5 performs secondary clamping on the stone to ensure the stability of the entire cutting process and improve the quality of the finished product. A lead screw nut pair 410 is provided between the rotating shaft box 41 and the frame, which can drive the rotating shaft box 41 to move, thereby adjusting the position of the cutting device 4 to adapt to plate-like stones of various thicknesses.

[0027] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
