[0022] By starting the two hydraulic cylinders 29, the telescopic ends of the two hydraulic cylinders 29 are extended, thereby driving the first slider 27 and the second slider 28 to slide in the through groove 4, and then the first slider 27 and the second slider 28 drive the first motor 21 to move, and then the second motor 22 is started, and then the second rotating shaft 9 on the second motor 22 rotates, and then the second rotating shaft 9 drives the saw blade 23 to rotate, and when the saw blade 23 contacts the cloth, the cloth is cut, and the first motor 21 is started to drive the first rotating shaft 6 to rotate, and then the first rotating shaft 6 rotates the screw rod 25 to rotate, and then the screw rod 25 drives the moving block 24 to move horizontally, and the connecting plate 30 is provided to guide the moving block 24, so that its movement is more stable, and the moving block 24 drives the saw blade 23 to move horizontally to cut the cloth, and then the cloth is cut by the saw blade 23 so that the cutting surface of the cloth is smooth and flat, thereby improving the working efficiency of the cloth cutting machine.

[0023] The positioning mechanism 14 includes a positioning plate 141, a spring 142, a connecting rod 143, a fixing plate 144 and a clamping block 145.

The clamping block 145 is placed in the annular groove 16 and is fixedly connected to the connecting rod 143.

[0024] By rotating the connecting rod 143, the clamping block 145 is driven to move in the annular groove 16 until the clamping block 145 corresponds to the connecting groove 19. The elasticity of the spring 142 causes the connecting rod 143 to move downward, thereby driving the clamping block 145 to move from the annular groove 16 to the connecting groove 19, and then move out of the connecting groove 19 until the connecting rod 143 drives the fixing plate 144 to squeeze the cloth, thereby fixing the cloth, thereby facilitating the cutting mechanism 2 to cut the cloth.

[0025] Working principle: first, place the cloth to be cut on the roller 18, then pull the cloth so that both ends of the cloth enter the guide groove 11, and then pull up the connecting rod 143 so that the fixed plate 144 squeezes the spring 142, until the block 145 passes through the connecting groove 19 and extends into the annular groove 16, then rotate the connecting rod 143, thereby driving the block 145 to engage with the annular groove 16, and then the fixed plate 144 is raised and fixed. When the cloth passes through the positioning plate 141, the connecting rod 143 is rotated again until the block 145 corresponds to the connecting groove 19, and then the connecting rod 143 is released, the squeezing force of the spring 142 is reduced and then rebounds to drive the connecting rod 143 to drive the fixed plate 144 to move downward until the fixed plate 144 contacts the cloth, thereby fixing the cloth, and then starting two hydraulic The cylinder 29 extends the telescopic ends of the two hydraulic cylinders 29, thereby driving the first slide block 27 and the second slide block 28 to slide in the two through grooves 4, thereby driving the movable block 24 to move downward, and then starting the second motor 22 to drive the second rotating shaft 9, and then the second rotating shaft 9 drives the saw blade 23 to rotate until the saw blade 23 contacts and cuts the cloth, and then starts the first motor 21, thereby rotating the first rotating shaft 6, and then the first rotating shaft 6 rotates the lead screw 25 to rotate. Since the lead screw 25 is threadedly connected to the threaded hole 7 on the movable block, the movable block starts to move horizontally with the rotation of the lead screw 25, and then cuts the cloth. By providing a knife groove 12, the electric saw can cut the cloth placed in the guide groove 11 to prevent the saw blade 23 from being obstructed during cutting.
