[0028] The operation process of the zipper cutting device of the utility model is as follows: when cutting the zipper, the rolled zipper strip is first conveyed to the transmission roller 202 through the guide roller 201. According to the width of the zipper strip, the distance between the two limit blocks 203 is adjusted, and the limit blocks 203 are fixed on the guide roller 201. Then the elastic pressing plate 204 is lifted, and the zipper strip is conveyed between the pressing rollers 402. The elastic pressing plate 204 presses the zipper strip on the workbench 1 to avoid uneven tightness during subsequent transmission, which causes errors in the cutting length and is difficult to cut. The zipper strip is conveyed to the pressing roller 402. The upper and lower pressing rollers 402 are parallel and are respectively installed in the bracket 401 and the workbench 1, and the position of the gap between the two pressing rollers 402 is level with the workbench 1. A groove is provided in the middle of the pressing roller 402 so that the chain teeth in the middle of the zipper strip can pass through, and the cloth strips of the zipper strip are pressed tightly on both sides. The zipper strip passes through the upper cutter 403, and the two sides are clamped by the pneumatic finger cylinder 301. The second motor 3010 is started, and the second motor 3010 drives the second screw rod 305 to rotate, so that the slider seat 306 moves backward. The pneumatic finger cylinder 301 is fixed on the slider seat 306, so that the pneumatic finger cylinder 301 moves backward. Move to the cutting distance, the second motor 3010 stops rotating, and the control cylinder 405 drives the upper cutter 403 to move downward to cut the zipper strip. The pneumatic finger cylinder 301 is opened, so that the zipper strip falls onto the conveyor belt 501. The conveyor belt 501 rotates to one side of the operating table 6, and the cut zipper strip is transferred to the collection table 502. The zipper strips on the collection table 502 are stacked vertically for easy collection. The second motor 3010 rotates in the opposite direction to move the pneumatic finger cylinder 301 to the first movable seat 302. The pneumatic finger cylinder 301 clamps the zipper strip and repeats the work. It does not require manual operation and is simple and convenient. If the width of the zipper strip is adjusted, the first motor 309 is started. The first motor 309 drives the first screw rod 303 to rotate, and the two first movable seats 302 installed on the first screw rod 303 move relative to each other along the axial direction of the first screw rod 303. The two first movable seats 302 are connected to the two second movable seats 304 through the guide rod 307 and the second screw rod 305 respectively. The movement of the first movable seat 302 causes the two second movable seats 304 to move relative to each other along the guide rail 308. The slider seat 306 installed on the guide rod 307 and the second screw rod 305 respectively also moves relative to each other along the axial direction of the first screw rod 303. The pneumatic finger cylinders 301 fixed on the slider seat 306 also move relatively, and the distance between the pneumatic finger cylinders 301 is consistent with the width of the zipper strip, so that the zipper strip clamped by the pneumatic finger cylinders 301 always maintains flatness, making cutting smoother.
