Then rotate the manual screw rod 5. Through its threaded cooperation with the sliding plate 6, the sliding plate 6 and the cutting knife 7 can be horizontally translated. At this time, observe the position of the guiding head 9 on the measuring scale 8, and then adjust it to the specified position and tighten the setscrew. At this time, the cutting length is determined;

[0027] Then, the whole zipper is placed on the horizontal table 3 and the support plate 19, and then one end of the zipper is placed against the standing plate 2, and then the output shafts of the single-axis cylinder 10 and the single-axis cylinder 20 are started to extend, so that the pressing plate 13 and the pressing plate 21 are lowered, and finally the zipper is clamped, and then the motor is started in the forward direction, and its output shaft drives the electric screw 16 to rotate, so that under the thread cooperation between the electric screw 16 and the slide seat 17, the slide seat 17 moves horizontally with the mold frame 18, so as to gradually straighten and flatten the whole chain, until it is completely straightened and flattened and then the motor is turned off, and then the output shaft of the double-axis cylinder 22 is started to extend, and the cutter 7 is lowered, and finally the zipper is cut;

[0028] After cutting, first start the output shafts of single-axis cylinder 10 and single-axis cylinder 20 to retract and loosen the zipper, then start the motor in reverse to bring the mold frame 18 back to its original position, then remove the cut zipper, move the remaining zipper forward so that its end contacts the station plate 2 again, and then repeat the above action to perform another cutting action, and repeat this process until the entire zipper is cut.
