The two ends of the support 3 are arranged on the two sides of the movable platform 10, and the cutting edge of the cutter 8 faces downwards. The welding of 3 top right sides of support has horizontal roof 4, roof 4 below is equipped with L-shaped knife rest 5, cutter 8 passes through screw fixed connection with the inner face of knife rest 5. The welding of being close to the right side in the support 3 has vertical curb plate, the symmetry is equipped with two vertical tracks 7 on the curb plate, track 7 passes through screw fixed connection with the curb plate. The cross section of the rail 7 is in a dovetail shape, and two dovetail grooves which are respectively matched with the corresponding rail 7 in a sliding mode are symmetrically arranged on the left side of the tool rest 5. Three air cylinders 6 used for driving the cutter 8 to move up and down are transversely and uniformly distributed between the cutter rest 5 and the top plate 7, and the three air cylinders 6 are vertically arranged. The cylinder bodies of the three cylinders 6 are fixedly connected with the top plate 4 through screws, and the push rods of the three cylinders 6 are fixedly connected with the tool rest 5 through screws. A driving device for driving the movable platform 10 to move longitudinally is arranged between the movable platform 10 and the fixed platform 1, and a follow-up device for driving the support 3 to move synchronously with the movable platform 10 is arranged between the base 15 and the support 3.

The driving device drives the movable platform 10 and the cloth piece 9 to move rightwards along the longitudinal direction, when the movable platform moves to a set numerical value, the follow-up device drives the support 3 and the cutter 8 on the support 3 to synchronously move rightwards along with the movable platform 10, and at the moment, the cloth piece 9 and the cutter 8 are relatively static. Then the cutter 8 moves downwards under the drive of the cylinder 6 to cut the cloth piece 9, then the cylinder 6 drives the cutter 8 to move upwards to leave the cloth piece 9, and then the follow-up device drives the bracket 3 to rapidly move reversely and reset. The above process is repeated, so that the cloth piece 9 is in continuous motion during cutting, and the cutting efficiency of the cloth piece 9 is improved. And meanwhile, the continuous movement is also beneficial to prolonging the service life of the driving device.

The driving device is a first linear module 12 longitudinally arranged between the fixed platform 1 and the movable platform 10, and the first linear module 12 is a ball screw linear module driven by a servo motor.

The movable platform 10 and the cloth piece 9 placed on the movable platform are driven by the first linear module 12 to move from the left side to the right side of the bracket 3, so that the cloth piece 9 is cut. When the cloth piece moves to the right side of the bracket 3 and the cutting operation is finished, the cylinder B13 acts to enable the movable platform 10 to move upwards, and therefore the roller 2 and the corresponding first sliding groove 17 are separated. Then, the movable platform 10 is horizontally rotated by 90 degrees to align the second sliding grooves 18 with the corresponding rollers 2, and then the air cylinder b 13 is operated to move the movable platform 10 downwards and make the rollers 2 enter the corresponding second sliding grooves 18. Then the first linear module 12 drives the movable platform 10 to move leftwards and reset, and the cutting of the cloth piece 9 can be continued. Therefore, the utility model can cut the cloth piece 9 into a plurality of rectangular small pieces in a net shape.
