[0041] The working principle of the present invention is as follows: before processing, the shoe upper is clamped on the clamping seat 56 in advance, and the shoelace is placed on the clamping seat 56 at the same time. The two hard ends of the shoelace are clamped on the two clamping claws 57 on the front side of the clamping seat 56 respectively, and the push-pull cylinder 52 drives the clamping seat 56 to slide into the working area along the sliding rail 51, and then the lifting cylinder 54 drives the clamping seat 56 to rise to the clamping range of the inner clamping pneumatic clamp 61, and at the same time, the clamping claws of the inner clamping pneumatic clamp 61 on both sides move inward and the clamping arms of the inner clamping pneumatic clamp 61 are opened. After the clamping seat 56 is lifted into place, the inner clamping pneumatic clamp 61 closes its claws to clamp the two hard ends of the shoelace, and then the clamping seat 56 descends and pushes forward until the inner clamping pneumatic clamp 61 The clamping jaws are located at the position of the first group of shoelace holes on the upper, and then the clamping seat 56 rises until the clamping jaws of the inner clamping pneumatic clamping jaws 61 are located between the inner end surfaces of the upper, and then the clamping jaws of the inner clamping pneumatic clamping jaws 61 on both sides move to both sides, so that the two hard ends of the shoelace are respectively inserted into the first group of shoelace holes on the upper, and then the slide cylinder 21 drives the outer clamping pneumatic clamping jaws 22 to approach the upper, and the two hard ends of the shoelace passing through the first group of shoelace holes on the upper are clamped by the outer clamping pneumatic clamping jaws 22, and then the inner clamping pneumatic clamping jaws 61 release the clamping of the shoelace, and the slide cylinder 21 drives the outer clamping pneumatic clamping jaws 22 to retreat to bring the shoelace out, and then the pressing plate lifting cylinder 54 pushes the pressing plate to rise and press against the lower side of the hard end of the shoelace;

When the shoelaces are all pulled out, the pressing rod 37 is subjected to the resistance of the shoelaces, so that the pressing plate 39 rotates and tilts upward along the rotating bearing 391 to achieve avoidance.

[0043] Then the belt pressing mechanism 3 is reset, and during the reset process, the belt pressing rod 37 contacts the stop bar 35 to reset the belt pressing plate 39;

[0044] Then the inner pneumatic clamping jaw 61 moves outward to clamp the two hard ends of the shoelace again, and the rear rotating cylinder drives the fixing plate 62 to rotate 360 ​​degrees, so that the two shoelaces cross, and the clamping seat 56 descends, and then the inner pneumatic clamping jaw 61 moves inward, and the clamping seat 56 slides forward and lifts up to make the clamping jaws of the inner pneumatic clamping jaw 61 located at the position of the second group of shoelace holes on the vamp, and then the inner clamping mechanism 6, the outer clamping mechanism 2, the pressing mechanism 3, and the clamping mechanism 5 cooperate to repeat the above work in a cycle until the shoelace threading work is completed.
