Description

Technical Field

[0001] The invention belongs to the technical field of zipper equipment and relates to a guide rail head threading machine and a threading method thereof. Background Art

[0002] Zippers are a common connector on various types of clothing, bags, tents and other items. Depending on the different items the zipper is used for, the types of zipper pullers are often different. Among them, the guide puller is a puller with a special structure. It can be used on both sides and is often used on some double-sided products, such as clothing that can be worn on both sides.

[0003] For example, CN201821813806.2 discloses a guide rail head, including a zipper body, an upper cover fixed on the upper part of the zipper body, the zipper body and the upper cover constitute a zipper core, the outside of the zipper core is provided with a clearance-fitting and movable cap, a horse hook forms a locking structure with the core and the cap respectively, and a through hole is provided on the back side of the zipper body. When the pull piece is freely placed, the hook lock penetrates the through hole and contacts with the cloth piece to form a self-locking structure.

[0004] When the chain belt passes through the above-mentioned guide rail head, it is necessary to first push the cap to move closer to the zipper body so that the hook lock retracts into the through hole, that is, after the safety of the guide rail head is released, the chain belt can smoothly pass through the guide rail head. Since ordinary head-threading machines cannot release the safety of the guide rail head, that is, the chain belt cannot pass through the guide rail head, a head-threading machine that can release the safety of the guide rail head is needed for the special structure of the guide rail head, so that the chain belt can pass through the guide rail head.

[0005] For example, CN201720336487.X discloses a slider threading machine, comprising a slider threading mold and a belt divider for clamping the slider; the belt divider comprises a safety release member for pushing the slider to release the safety, the safety release member is connected to a safety release driving device, and the safety release driving device is used to push the safety release member to move toward the slider; and also comprises a reset driving device for resetting the safety release member.

[0006] The above-mentioned pull head threading machine pushes the cap of the guide rail head to move through the safety release piece, so that the safety of the guide rail head is released, and then the chain belt can be smoothly passed through the guide rail head. However, when the chain belt passes through the guide rail head, in order to enable the chain belt to pass through the guide rail head quickly, the chain belt will generate a large thrust on the guide rail head. If there is no corresponding fixing structure, the guide rail head may be pushed out of the threading head, causing the threading machine to be unable to perform the threading work normally. Therefore, in addition to the device for releasing the safety of the guide head, the pull head threading machine also needs to have a structure that can fix the guide rail head during threading.

[0007] For example, CN201510248061.4 discloses a zipper threading machine, including a frame, a zipper pulling mechanism, a zipper sensing detection device, a slider mold, a feeding head, a zipper sliding groove and a strip pin positioning device. The slider mold is provided with a slider safety release mechanism, and the slider safety release mechanism includes a safety slider, and a hook is provided on the safety slider.

[0008] When the above-mentioned threading machine is threading the slider and the slider is fed into the slider mold, the hook needle will penetrate into the slider tab, thereby hooking the slider, so that the chain belt will not push the slider off the slider mold when passing through the slider. However, when the pull tab of the guide rail head is hooked by the hook needle, friction will be generated between the pull tab of the guide rail head and the cap. When the force of the pull tab being hooked by the hook needle is too large, the friction between the pull tab and the cap will also be large, making it difficult to push the cap, that is, it creates a certain obstacle to the equipment to release the safety of the guide rail head, causing the chain belt to be unable to pass through the guide rail head smoothly.

[0009] To address the above problems, a rail head piercing machine suitable for piercing the rail head can be designed, which can fix the position of the rail head during piercing and does not affect the normal release of the rail head safety, as well as a piercing method for the rail head using the piercing machine. Summary of the invention

[0010] In view of the above problems, the present invention provides a guide rail head piercing machine and a piercing method thereof. When performing the piercing work, the piercing machine can fix the position of the guide rail head without affecting the normal release of the guide rail head safety. The piercing method used by the piercing machine can effectively and stably realize the piercing work of the guide rail head.

DETAILED DESCRIPTION

[0038] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0039] The present invention will be further described below with reference to specific embodiments of the present invention.

[0040] like Figure 1-7As shown, a guide head threading machine comprises a guide head mold base 1, a positioning groove 11 for placing the guide head is formed on the guide head mold base 1, a minute hand 2 which can move up and down relative to the positioning groove 11 is provided on one side of the guide head mold base 1, and a first power member 21 which can control its movement is connected to the minute hand 2, a hook needle 3 for hooking the guide head pull tab is provided in the guide head mold base 1, a linkage block 31 is formed at the lower end of the hook needle 3, and a linkage groove 311 is formed on the linkage block 31, a second power member 4 for controlling the movement of the linkage block 31 is provided on one side of the guide head mold base 1, a connecting seat 41 aligned with the connecting groove 311 is provided on the second power member 4, a connecting rod 7 is connected between the connecting block 31 and the second power member 4, the connecting rod 7 passes through the connecting groove 311 and is inserted into the connecting seat 41, the connecting rod 7 can be raised and lowered relative to the connecting seat 41, and the force of the second power member 4 on the hook needle 3 can be changed by raising and lowering the linkage rod 7. Specifically, in the threading machine, the guide rail head mold base 1 clamps the guide rail head through the positioning groove 11, and the pull tab of the guide rail head hangs downward. When the threading machine performs threading, the hook needle 3 moves toward the bottom of the guide rail head in the positioning groove 11 and passes through the through hole on the guide rail head pull tab. The second power member 4 starts to work and drives the linkage block 31 to move through the linkage rod 7. The linkage block 31 pulls the hook needle 3 while moving, so that the hook needle 3 tightens the guide rail head through the through hole on the guide rail head pull tab. The guide rail head can be fixed in the positioning groove 11. At this time, the first power part 21 controls the minute hand 2 to move downward. The minute hand 2 pushes the cap of the guide rail head to move during the downward movement, so that the safety of the guide rail head is released. The minute hand 2 also separates the chain belt while moving downward. After the guide rail head safety is released and the chain belt is separated, the threading machine passes the chain belt through the guide head to complete the threading work. During this process, the hook needle 3 tightens the guide head pull tab to prevent the guide head from being pushed out of the positioning groove 11 of the guide head mold base 1 when the chain belt passes through. Since the guide head pull tab is connected to the guide head cap, in order to prevent the hook needle 3 from pulling the guide head pull tab with too much force, that is, causing excessive friction between the guide head pull tab and the guide head cap, the minute hand 2 cannot push the guide head cap to move when moving downward, thereby causing the guide head safety to fail to be released normally and the chain belt to fail to pass through the guide head, the second power member 4 controls the linkage block 31 to pull the hook needle 3 with a force that should be adjusted to an appropriate range.The linkage rod 7 is formed with a portion that can be pressed against the linkage block 31. By adjusting the distance of the linkage rod 7 inserted into the connecting seat 41 on the second power member 4, the tightness of the portion on the linkage rod 7 against the linkage block 31 can be changed, so that the force generated by the second power member 4 on the linkage block 31 during operation can be adjusted. The force of the linkage block 31 when pulling the hook needle 3 to hook the rail head pull tab also changes accordingly, so that when the hook needle 3 hooks the rail head pull tab, the friction generated between the rail head pull tab and the cap will not hinder the minute hand 2 from pushing the rail head cap, ensuring that the safety of the rail head can be released normally, and the head threading machine can smoothly pass the chain belt through the rail head after the chain is split. The first power member 21 and the second power member 4 can be motors or cylinders to achieve corresponding movements.

[0041] Furthermore, a thread is formed in the connection seat 41. Specifically, the linkage rod 7 and the connection seat 41 can be connected by threaded engagement, and by twisting the linkage rod 7, the tightness of the part on the linkage rod 7 against the linkage block 31 can be adjusted, and the distance of the linkage rod 7 inserted into the connection seat 41 can be fixed.

[0042] like Figure 2 As shown, a guide hole 12 is formed on the rail head mold base 1 for the linkage block 31 to extend out, and the linkage block 31 can move up and down in the guide hole 12. Specifically, the guide hole 12 limits the moving range of the linkage block 31, further preventing the linkage block 31 from pulling the hook needle 3 with too much force, causing excessive friction between the cap of the rail head and the pull tab when the hook needle 3 hooks the rail head pull tab.

[0043] like Figure 2-4 As shown, a U-shaped groove 13 is formed in the rail head mold base 1 for the hook needle 3 and the rail head pull tab to extend into. Specifically, the U-shaped groove provides a space for the hook needle 3 to hook the pull tab of the rail head after the pull tab of the rail head is hung down, and facilitates the movement of the hook needle 3.

[0044] Furthermore, a support platform 14 aligned with the positioning groove 11 is formed on the guide rail head mold base 1. Specifically, the support platform 14 is used to support the chain belt passing through the guide rail head.

[0045] like Figure 1 As shown, the guide rail head mold base 1 is connected with a limit plate 5 that abuts against the upper end of the second power member 4, and a matching groove 51 is formed on the limit plate 5 for the connection seat 41 to extend into. Specifically, the limit plate 5 abuts against the upper end of the second power member 4, limits the movement stroke of the second power member 4 when working, fixes the connection seat 41, and plays a guiding role when the second power member 4 pulls the linkage rod 7.

[0046] like Figure 2-4 As shown, a stopper 6 is provided on one side of the minute hand 2. Specifically, the stopper 6 is used to prevent the minute hand 2 from tilting when descending.

[0047] Furthermore, the bottom end of the minute hand 2 is a plane. Specifically, the plane-shaped bottom end can prevent the minute hand 2 from scratching the surface of the guide rail head when moving downward, thereby affecting the product appearance of the guide rail head.

[0048] like Figure 3 As shown, a push groove 22 for the rail head cap to be inserted into is formed on the minute hand 2. Specifically, when the minute hand 2 descends, the cap of the rail head is inserted into the push groove 22 and pushed, so as to prevent the cap of the rail head from affecting the descent of the minute hand 2.

[0049] Furthermore, an inclined surface is formed in the push groove 22. Specifically, when the cap of the guide rail head enters the push groove 22 of the minute hand 2, the cap of the guide rail head abuts against the inclined surface in the push groove 22, increasing the contact area between the cap of the guide rail head and the minute hand 2, making it easier for the minute hand 2 to push the cap of the guide rail head.

[0050] like Figure 1-7 As shown, a guide rail head threading method of a guide rail head threading machine comprises the following steps:

[0051] 1) Place the rail head to be pierced into the positioning groove 11 on the rail head die base 1, hang the pull tab of the rail head, extend the hook needle 3 to the bottom of the rail head, and pass through the through hole on the pull tab of the rail head to hook the pull tab of the rail head;

[0052] 2) Pass the linkage rod 7 through the linkage groove 311 on the linkage block 31 and insert it into the connecting seat 41 on the second power member 4, and adjust the distance of the linkage rod 7 inserted into the connecting seat 41 until the hook needle 3 hooks the rail head pull tab tightly, and the minute hand 2 descends to smoothly push the rail head cap;

[0053] 3) The second power member 4 works and pulls the linkage block 31 downward through the linkage rod 7, and the linkage block 31 pulls the hook needle 3 downward, and the hook needle 3 tightens the rail head through the through hole of the rail head pull tab, so that the rail head is fixed on the rail head mold base 1;

[0054] 4) Bring the chain belt close to the guide rail head, the first power member 21 works, and controls the minute hand 2 to descend. During the descent, the minute hand 2 contacts the cap of the guide rail head and pushes the cap of the guide rail head to move. The safety of the guide rail head is released, and the minute hand 2 continues to descend until the chain belt close to the guide rail head is separated. The separated chain belt continues to move and passes through the guide rail head.

[0055] Specifically, in this method, the distance that the linkage rod 7 is inserted into the connection seat 41 should be adjusted according to the force required by the hook needle 3 when tightening the pull tab of the guide rail head. If the force is too large, it is easy to cause a large friction between the pull tab of the guide rail head and the cap, which hinders the minute hand 2 from pushing the cap of the guide rail head to move. If the force is too small, the hook needle 3 cannot tighten the guide rail head to fix the guide rail head on the guide rail head mold seat 1. The linkage rod 7 is formed with a portion that can abut against the linkage block 31. By adjusting the distance that the linkage rod 7 is inserted into the connection seat 41, the tightness of the portion of the linkage rod 7 abutting against the linkage block 31 can be changed, so that the force of the second power member 4 acting on the linkage block 31 during operation can be changed, and the force of the linkage block 31 pulling the hook needle 3 and the force of the hook needle 3 tightening the pull tab of the guide rail head will also change accordingly. The force required when the hook needle 3 tightens the rail head pull tab is affected by factors such as equipment scale and rail head size, and the distance that the linkage rod 7 is inserted into the connecting seat 41 should be adjusted accordingly.

[0056] The distance that the linkage rod 7 is inserted into the connecting seat 41 needs to be adjusted to the optimal distance through continuous testing. During the testing process, the second power member 4 works, and the second power member 4 pulls the linkage block 31 to move through the linkage rod 7, and the hook needle 3 hooks the guide head pull tab so that the guide head is fixed in the positioning groove 11 of the guide head mold seat 1. The first power member 21 then works, and the first power member 21 controls the minute hand 2 to descend, and the minute hand 2 contacts the guide head cap. According to the pushing condition of the minute hand 2 on the guide head cap when the minute hand 2 contacts the guide head cap, and the release condition of the guide head safety, the distance that the linkage rod 7 is inserted into the connecting seat 41 is adjusted until the guide head pull tab is hooked by the hook needle 3, and the minute hand 2 can smoothly push the guide head cap, so that the guide head safety is smoothly released. At this time, the distance that the linkage rod 7 is inserted into the connecting seat 41 is the optimal distance.

[0057] like Figure 5-7 As shown, when the rail head is not released, the hook lock 8 extends from the middle of the rail head, and the hook lock 8 prevents the chain belt from passing through the middle of the rail head. When the rail head cap is pushed and the rail head is released, the hook lock 8 in the middle of the rail head retracts, and the chain belt can pass through the middle of the rail head normally.

[0058] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
