[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. When the threading machine is working as a whole, the cloth tape is transferred to the tape feeding plate, and then the tape is fed to the inside of the machine head. At this time, the straight upper knife in the machine head cuts off, and the slider is transmitted to the position of the slider bottom plate by the vibration plate, and then pushed into the flip mechanism by the top slider seat, and the reverse-threading lower mold moves upward, and then the slider is sent to the reverse-threading lower mold by the feeding part of the machine head. The hook cylinder drives the reverse-threading small mold base to drive the small mold forward, and after clamping the slider, the cylinder drives the pull-tab fixing plate to move toward the machine head. After clamping the slider, the feeding part of the machine head retreats, and the next action starts after resetting. The clamp seat clamps the sent zipper and pulls it to the left to insert the zipper. After a certain length of insertion, the mold is released, and then the straight upper knife cuts the zipper, and the next cycle begins;

[0020] 2. When the flipping mechanism is working, the rotating cylinder is started to rotate counterclockwise, and the counterclockwise rotation of the rotating cylinder drives the rotating cylinder rotor to rotate counterclockwise, thereby driving the connecting rod of the material receiving seat to rotate counterclockwise, and then driving the material receiving seat 1 and the material receiving seat 2 to rotate counterclockwise. At this time, the needle cylinder and the pull-tab block will move upward counterclockwise at the same time. When the material receiving seat 1 and the material receiving seat 2 rotate 90° counterclockwise, the rotating cylinder stops. At this time, the material receiving seat 1 and the material receiving seat 2 are aligned with the top pull head seat, and then the top pull head seat is driven by the cylinder to push the material downward to push the double pull tab pull heads into the material receiving seat 1 and the material receiving seat 2. Then the needle cylinder is started to drive the movable shaft of the needle cylinder to push the double pull tab pull heads into the groove of the pull tab block to fix the double pull tab pull heads, and then the rotating cylinder is reset, and the double pull tab pull heads are rotated to a horizontal state, waiting for the next step of operation; it solves the friendly transition between the various components in the process of the double pull tab pull head receiving, and it is not easy to cause material jamming or material stripping;

[0021] 3. When the mold mechanism is working, start the lower mold cylinder, and the lower mold cylinder pushes the reverse-penetrating lower mold to move upward. When the reverse-penetrating lower mold contacts the double-pull-tab upper mold, the lower mold cylinder stops; then the feeding cylinder drives the material receiving seat 1 and the material receiving seat 2 to approach the reverse-penetrating lower mold. At this time, the double-pull-tab pullers on the material receiving seat 1 and the material receiving seat 2 are sent to the reverse-penetrating lower mold, and then the hook cylinder pushes the reverse-penetrating small mold base to drive the small mold to move close to the reverse-penetrating lower mold. When the small mold clamps the double-pull-tab puller at the reverse-penetrating lower mold, the start cylinder drives the pull-tab fixing plate to move toward the double-pull-tab upper mold. After the pull-tab fixing plate clamps the double-pull-tab puller, the material receiving seat 1 and the material receiving seat 2 are reset, and after resetting, they wait for the next process; the problem of giving way to the double-pull-tab puller when the double-pull-tab puller is pushed into the mold assembly is solved, and the problem of placing the double-pull-tab puller after the mold assembly receives the material is also solved.

[0049] Furthermore, the hook needle cylinder is arranged on the mold cylinder plate 39 .

[0050] In this embodiment, when the mold mechanism 3 is working, the lower mold cylinder is started, and the lower mold cylinder pushes the reverse-penetrating lower mold 36 to move upward. When the reverse-penetrating lower mold 36 contacts the double-pull-tab upper mold 32, the lower mold cylinder stops; then the feeding cylinder drives the material receiving seat 1 234 and the material receiving seat 235 to approach the reverse-penetrating lower mold 36. At this time, the double-pull-tab pull head 6 on the material receiving seat 1 234 and the material receiving seat 235 is sent to the reverse-penetrating lower mold 36, and then the hook cylinder pushes the reverse-penetrating small mold base 38 to drive the small mold 37 to move close to the reverse-penetrating lower mold 36.

[0051] The working principle and use process of the present invention are as follows: when the threading machine is working as a whole, the cloth tape is passed into the tape feeding plate 4, and then the tape is fed into the machine head 31. At this time, the straight upper knife in the machine head 31 cuts off, and the slider 6 is transmitted by the vibration plate 1 to the position of the slider bottom plate 21, and then pushed into the flip mechanism 23 by the top slider seat 22, and the reverse threading lower mold 36 moves upward, and then the slider 6 is sent to the reverse threading lower mold 36 by the feeding part of the machine head 31, and the hook cylinder drives the reverse threading small mold base 38 to drive the small mold 37 to move forward, and after clamping the slider 6, the cylinder 33 drives the pull-tab fixing plate 35 to move toward the machine head 31. After clamping the slider 6, the feeding part of the machine head 31 retreats, and the next step of action is started after resetting, and the clamp seat 5 clamps the zipper sent out and pulls it to the left to insert the zipper. After a certain length of insertion, the mold is released, and then the zipper is cut off by the straight upper knife, and the next step of the cycle is entered;

[0052] When the flip mechanism 23 is working, the rotating cylinder is started to rotate counterclockwise, and the rotating cylinder rotates counterclockwise to drive the rotating cylinder rotor 232 to rotate counterclockwise, thereby driving the material receiving seat connecting rod 233 to rotate counterclockwise, and then driving the material receiving seat 1 234 and the material receiving seat 235 to rotate counterclockwise. At this time, the needle cylinder 236 and the pull-tab block 238 will move upward counterclockwise at the same time. When the material receiving seat 1 234 and the material receiving seat 235 rotate 90° counterclockwise, the rotating cylinder stops. At this time, the material receiving seat 1 234 and the material receiving seat 235 are aligned with the top pull head seat 22, and then the top pull head seat 22 is driven by the cylinder to push the material downward to push the double pull tab pull head 6 into the material receiving seat 1 234 and the material receiving seat 235, and then the needle cylinder 236 is started to drive the needle cylinder movable shaft 237 to push the double pull tab pull head 6 into the groove of the pull tab block 238 to fix the double pull tab pull head 6, and then the rotary cylinder is reset to rotate the double pull tab pull head 6 to a horizontal state, waiting for the next step of operation;

[0053] Among them, when the mold mechanism 3 is working, the lower mold cylinder is started, and the lower mold cylinder pushes the reverse-penetrating lower mold 36 to move upward. When the reverse-penetrating lower mold 36 contacts the double-pull-tab upper mold 32, the lower mold cylinder stops; then the feeding cylinder drives the material receiving seat 1 234 and the material receiving seat 235 to approach the reverse-penetrating lower mold 36. At this time, the double-pull-tab pull head 6 on the material receiving seat 1 234 and the material receiving seat 235 is sent to the reverse-penetrating lower mold 36, and then the hook cylinder pushes the reverse-penetrating small mold base 38 to drive the small mold 37 to move close to the reverse-penetrating lower mold 36. When the small mold 37 clamps the double-pull-tab pull head 6 at the reverse-penetrating lower mold 36, the cylinder is started to drive the pull tab fixing plate 35 to move toward the double-pull-tab upper mold 32. After the pull tab fixing plate 35 clamps the double-pull-tab pull head 6, the material receiving seat 1 234 and the material receiving seat 235 are reset, and after resetting, they wait for the next step.
