Double-pull-tab pull head pushing mold structure for double-pull-tab cutting and penetrating machine

Abstract

According to the double-pull-tab pull head pushing mold structure for the double-pull-tab cutting and penetrating machine, in the working process, a lower mold air cylinder is started, the lower mold air cylinder pushes a reverse penetrating lower mold to move upwards, and after the reverse penetrating lower mold makes contact with a double-pull-tab upper mold, the lower mold air cylinder stops; then a feeding air cylinder drives a first material receiving base and a second material receiving base to approach a reverse penetrating lower die, at the moment, the double-pull-piece pull heads on the first material receiving base and the second material receiving base are conveyed to the reverse penetrating lower die, then a bearded needle air cylinder pushes a reverse penetrating small die base to drive a small die to move towards the position close to the reverse penetrating lower die, and after the small die clamps the double-pull-piece pull heads on the reverse penetrating lower die, the double-pull-piece pull heads on the reverse penetrating lower die are clamped by the bearded needle air cylinder. The air cylinder is started to drive the pull tab fixing plate to move towards the double-pull-tab upper die, after the pull tab fixing plate clamps the double-pull-tab pull head, the first material receiving seat and the second material receiving seat are reset, and the next procedure is waited after resetting; by means of the design, the avoiding problem of the double-pull-piece pull head pushed into the mold assembly is solved, and the placing problem of the double-pull-piece pull head after material receiving of the mold assembly is also solved.

Description

Technical Field

[0001] The invention belongs to the technical field of double-pull-tab cutting and plugging machines, and in particular relates to a double-pull-tab pull head pushing mold structure for the double-pull-tab cutting and plugging machine. Background Art

[0002] The double-tab cutting and threading machine is an automated device for installing double-tab sliders on zippers. The double-tab cutting and threading machine commonly used is used for double-tab sliders. When the double-tab slider enters the slider mold, the pull tab will not interfere with the end of the slider.

[0003] The existing double-tab pull-head cutting and threading machine cannot solve the problem of giving way to the double-tab pull-head after pushing the double-tab pull-head into the mold; and the problem of placing the double-tab pull-head after the mold is connected with the material cannot be solved; therefore, the present invention proposes a double-tab pull-head pushing mold structure for the double-tab pull-head cutting and threading machine to solve the above problems. Summary of the invention

[0005] The present invention is implemented as follows: a double-pull-tab pull-head pushing mold structure for a double-pull-tab cutting and threading machine includes a material receiving assembly and a mold assembly;

[0006] The material receiving assembly comprises a material receiving seat, the material receiving seat comprises a material receiving seat 1 and a material receiving seat 2, the material receiving seat 1 and the material receiving seat 2 are fixedly connected, and the material receiving seat 2 is provided with a double pull tab pull head;

[0007] The mold assembly includes a double-pull-tab upper mold, a cylinder and a reverse-penetrating lower mold. The output end of the cylinder is connected to a pull-tab fixing seat. A pull-tab fixing plate is provided on the pull-tab fixing seat. The double-pull-tab upper mold is located on the inner side of the pull-tab fixing plate. The reverse-penetrating lower mold is provided below the double-pull-tab upper mold. The reverse-penetrating lower mold is driven by the lower mold cylinder. A small mold is provided on the front side of the reverse-penetrating lower mold.

[0008] Preferably, the material receiving assembly further comprises a feeding upright plate, and a feeding seat upright plate is provided on the front side of the feeding upright plate.

[0009] Preferably, a rotating cylinder is provided on the front side of the feed seat stand, and the output end of the rotating cylinder is connected to the material receiving seat connecting rod.

[0010] Preferably, the material receiving seat is provided on the material receiving seat connecting rod.

[0011] Preferably, the small mold is arranged on a reverse small mold base.

[0012] Preferably, the reverse-piercing small mold base is driven by a hook cylinder.

[0013] Preferably, the crochet cylinder is arranged on the mold cylinder plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] During operation, the lower mold cylinder is started, 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 pullers at the reverse-penetrating lower mold, the starting 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 pullers, the material receiving seat 1 and the material receiving seat 2 are reset, and after resetting, they wait for the next step of the process; the design of the present invention solves the problem of giving way to the double-pull-tab pullers when the double-pull-tab pullers are pushed into the mold assembly, and also solves the problem of placing the double-pull-tab pullers after the mold assembly receives the materials.

[0037] The working principle and use process of the present invention are as follows: when working, the lower mold cylinder is started, and the lower mold cylinder pushes the reverse-penetrating lower mold 9 to move upward. When the reverse-penetrating lower mold 9 contacts the double-pull-tab upper mold 5, the lower mold cylinder stops; then the feeding cylinder drives the material receiving seat 1 2 and the material receiving seat 2 3 to approach the reverse-penetrating lower mold 9. At this time, the double-pull-tab pull head 4 on the material receiving seat 1 2 and the material receiving seat 2 3 will be sent to the reverse-penetrating lower mold 9, and then the hook cylinder pushes the reverse-penetrating small mold base 11 to drive the small mold 10 to move close to the reverse-penetrating lower mold 9. When the small mold 10 clamps the double-pull-tab pull head 4 at the reverse-penetrating lower mold 9, the cylinder 6 is started to drive the pull tab fixing plate 8 to move toward the double-pull-tab upper mold 5. After the pull tab fixing plate 8 clamps the double-pull-tab pull head 4, the material receiving seat 1 2 and the material receiving seat 2 3 are reset, and after resetting, they wait for the next step.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
