The working principle is as follows: when the cloth cutting machine works, a cloth roll is firstly installed on an installation frame, partial cloth is dragged to slide to a required position along a first bearing table 1 and a second bearing table 2, at the moment, a cutting knife 8 is positioned on the left side of the cloth, the cloth is clamped by two clamping cylinders 18 on the left side, the cloth is prevented from deviating during cutting, the cutting horizontality is ensured, then, a driving mechanism is started to enable two transmission screw rods 5 to rotate simultaneously, two first moving plates 6 drive a first rotating rod 7 and two cutting knives 8 to start moving towards the rear side to cut the cloth, an arc-shaped spring 10 pulls the two cutting knives 8 to be positioned in a relatively stable state, the two cutting knives 8 cut off the cloth from the side surface of the cloth, the phenomenon that a large cutting dragging force is generated on the cloth roll is avoided, the cutting accuracy is improved, the performance of the cloth is ensured, the deformation of the cloth is avoided, after the cutting knife 8 finishes cutting, the driving mechanism rotates reversely, the cutting knife 8 is driven to reset slowly, when the cutting knife 8 and the first moving plate 6 move to the original position, after the first sensor 19 detects that the first moving plate 6 reaches the original position, the first sensor 19 controls the first motor 12 to start, the first motor 12 drives the second rotating rod 13 and the two first transmission wheels 14 to rotate simultaneously, the fixing belt 16 is driven to transmit, the first connecting block 17 on the right side is driven to pass through the third sensor 22, the clamping cylinder 18 at the bottom of the first connecting block 17 on the right side is opened, a person takes out the cut cloth, so that the next cloth is conveyed to the right side conveniently, the clamping cylinder 18 at the bottom of the first connecting block 17 on the left side clamps the cloth, in the clockwise conveying process of the fixing belt 16, the cloth is pulled to move to the right side, the cloth is automatically pulled to the next cutting position slowly, when the first connecting block 17 at the bottom is driven by the fixing belt 16 to move to the left cutting position, when the cloth is sensed by the second sensor 20, the first motor 12 stops running, the edge of the cloth is clamped by the clamping cylinder 18 which is sensed by the second sensor 20 and begins to extend inwards, the cloth is prevented from moving when being cut, then the driving mechanism is started again, the cutting knife 8 is enabled to move backwards again, the cloth is cut automatically, the continuous and automatic cutting process of the cloth is achieved, therefore, when the cloth roll is produced by the centrifugal machine, the cloth roll is cut by the cutting device, the pulling mechanism is matched with the cutting mechanism, when the cutting mechanism is used for cutting, the pulling mechanism is used for tensioning and positioning the cloth, the stability when the cloth is cut is ensured, the cloth is prevented from being deformed when being cut, after the cutting is completed, the subsequent cloth is automatically pulled to the cutting position by the pulling mechanism, personnel are not required to pull the cloth for multiple times, and the position of the cloth can be accurately determined every time, the inconsistent cloth cutting length is avoided, and the cutting efficiency is improved.
