A rough plate 203 is arranged below the gang saw mounting frame 105, and the rough plate 203 is used for loading stone.

[0037] When the adjustment motor 126 rotates, the driving rod 121 rotates, and the driving ring 124 drives the second rotating rod 120 to move by utilizing the principle of thread transmission, and then the spacing between the saw blades 106 is accurately adjusted through the linkage of the scissor-fork structure.

[0038] The lifting unit 200 also includes a first synchronization shaft 204, a second synchronization shaft 205, a drive box 206 and a transmission box 207.

[0040] A lifting motor 211 is fixedly mounted on the transmission box 207 , and the lifting motor 211 is used to drive the second synchronous shaft 205 to rotate, serving as a power source for lifting the blank plate 203 .

[0041] Working principle:

[0042] Before starting cutting, according to the thickness requirement of the stone slab to be cut, the adjusting motor 126 is started, and the adjusting motor 126 drives the driving rod 121 to rotate. Since the threaded area 122 on the driving rod 121 is threadedly connected with the driving ring 124, and the fixing ring 125 limits the axial movement of the collar 123, when the driving rod 121 rotates, the driving ring 124 drives the second rotating rod 120 to move, and through the linkage of the first rotating rod 119 and the second rotating rod 120 in the scissor structure, the adjusting seat 117 slides on the crossbar 116, so as to accurately adjust the spacing of the saw blades 106 to the required size, and the adjusting motor 126 is turned off after the adjustment is completed.

[0043] First, place the stone block to be cut on the block plate 203 and start the lifting motor 211. The lifting motor 211 drives the second synchronous shaft 205 to rotate. The third bevel tooth 210 at the end of the second synchronous shaft 205 drives the first bevel tooth 208 in the transmission box 207 to rotate, and then the lead screw 201 in each drive box 206 rotates synchronously through the first synchronous shaft 204. Since the lead screw 201 is threadedly connected to the lifting sleeve 202, the block plate 203 rises accordingly, and the stone is lifted to a suitable cutting height so that it contacts the saw blade 106.

[0044] Next, the rotating motor 113 is started, the rotating motor 113 drives the pulley 114 to rotate, the toothed belt 115 transmits power to the flywheel 107 and the rotating shaft 108, the rotating shaft 108 rotates to cause the rocker 110 to swing, the rocker 110 drives the swing arm 111 to move, and the swing arm 111 pulls the gang saw mounting frame 105 to move back and forth on the guide rail 103, at which time the saw blade 106 runs at a high speed to cut the stone. During the cutting process, the speed of the rotating motor 113 can be appropriately adjusted according to the material and hardness of the stone to ensure the cutting quality.

[0045] After the cutting is completed, the rotary motor 113 is turned off, and the rough plate 203 is lowered by a certain distance to leave space for subsequent stone plate packaging. If cutting is required again, the above steps are repeated.
