Description

Technical Field

[0001] This application belongs to the field of zipper manufacturing technology, and in particular relates to a pusher mechanism and a zipper processing device. Background Technology

[0002] Zippers typically consist of toothed strips on both sides and a slider. The slider slides through the toothed strips to open and close the zipper. To prevent the slider from detaching from the toothed strips, a stop structure is required at the beginning and / or end of the toothed strips. This stop structure blocks the slider in its sliding direction, preventing it from detaching from the toothed strips.

[0003] In related technologies, during the zipper manufacturing process, teeth need to be aligned on the toothed belt before being pushed to a fixed size. Currently, the common method is to remove excess teeth by cutting to create spaces on the toothed belt for the installation of the stop structure. However, the cutting process can easily damage the toothed belt and generate a large amount of shavings.

[0004] Therefore, how to improve the yield rate of zipper processing is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0016] In some embodiments of this application, there are at least two first protrusions, the at least two first protrusions are spaced apart, and a first gap is formed between the at least two first protrusions;

[0017] And / or, there are at least two second bosses, the at least two second bosses are spaced apart, and a second gap is formed between the at least two second bosses;

[0018] The pusher is provided with a third protrusion, which is configured to pass through the first gap and / or the second gap to push the tooth.

[0019] In some embodiments of this application, the pusher moves along a first direction to push the tooth; wherein the first direction is perpendicular to a second direction, and the second direction is the direction in which the first fixing member and / or the second fixing member presses against the rack belt.

[0020] In some embodiments of this application, the tooth-pushing mechanism includes a pusher that extends along the second direction;

[0021] The pusher is at least partially tapered along the second direction, so that when the pusher moves along the second direction, it pushes the pusher to move along the first direction.

[0022] Secondly, this application also provides a zipper processing device, including the aforementioned tooth-pushing mechanism, which is used to push away at least some of the teeth on the toothed strip.

[0023] In some embodiments of this application, the number of tooth-pushing mechanisms is at least two, and the at least two tooth-pushing mechanisms are arranged opposite to each other to process at least two rack belts.

[0024] In some embodiments of this application, the zipper processing device includes a push cylinder, and the pusher mechanism includes a pusher element;

Detailed Implementation

[0035] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0036] It should be noted that when a component is referred to as being "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0037] It should be understood that the terms "length", "width", "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0039] It should be noted that zippers typically consist of toothed strips on both sides and a sliding component. The sliding component is slidably connected to the toothed strips on both sides to open and close the zipper. To prevent the sliding component from disengaging from the toothed strips, a stop structure needs to be provided at the beginning and / or end of the toothed strips. The stop structure can block the sliding component in the sliding direction to prevent it from disengaging from the toothed strips.

[0040] In related technologies, a very long toothed strip is typically manufactured first, and multiple teeth are injection molded onto the strip. Then, excess teeth are pushed out of the strip to create openings, allowing for the cutting of multiple zippers at these openings. Stop structures can also be installed at these openings to limit the movement of the sliding components. During zipper manufacturing, after arranging the teeth on the toothed strip, a tooth-pushing and sizing process is performed. This can be understood as arranging multiple teeth at intervals on the toothed strip. Sizing refers to determining the required length of the zipper to be divided on the toothed strip. Tooth pushing refers to removing excess teeth at the sizing positions (openings).

[0041] Currently, excess teeth are typically removed by machining to create openings in the rack for the installation of the stop structure. It's important to explain that the teeth are usually bonded to the rack via a connecting structure. Currently, this connecting structure is partially removed manually by cutting, but this process easily damages the rack and generates a large amount of shavings. Scratches on the rack affect the appearance of the rack and zipper, and even the garment containing the zipper; the shavings generated during processing also degrade the workshop environment.

[0042] Therefore, this application improves the related pusher mechanism and zipper processing device based on this.

[0043] Please refer to the following: Figure 1 , Figure 1 A schematic diagram of the tooth-pushing mechanism provided in this embodiment is shown. This tooth-pushing mechanism is used to process zippers. The zipper includes a toothed strip and multiple teeth, which are spaced apart and clamped onto the toothed strip. The tooth-pushing mechanism is used to push away at least some of the teeth. It should be explained that the teeth are provided with slots, and the toothed strip is embedded in the slots to fix the teeth and the toothed strip. In conventional technology, one side of the slot wall is usually cut off with a knife, which greatly reduces the connection stability between the toothed strip and the teeth, making it easier to remove the teeth.

[0044] The tooth-pushing mechanism includes a fixing component 100 and a tooth-pushing element. The fixing component 100 includes a first fixing element 110 and a second fixing element 120. The first fixing element 110 and the second fixing element 120 are positioned on opposite sides of the rack belt to clamp the rack belt. It is understood that the first fixing element 110 and / or the second fixing element 120 can be close to or away from the rack belt.

[0045] In one exemplary description, the first fastener 110 and the second fastener 120 are brought close to the rack belt until the first fastener 110 and the second fastener 120 abut against the rack belt to achieve clamping of the rack belt.

[0046] In another exemplary description, the first fastener 110 is disposed on the second fastener 120, and the rack belt is placed on the second fastener 120, and the rack belt is clamped by the first fastener 110 approaching the rack belt until the first fastener 110 abuts against the rack belt.

[0047] In another exemplary description, the first fastener 110 is disposed on the second fastener 120, and the rack belt is distributed below the first fastener 110. The rack belt is brought close to the second fastener 120 until it is pushed to the bottom of the first fastener 110 to clamp the rack belt.

[0048] In some embodiments, the toothed belt can be a cloth belt.

[0049] The pusher is at least partially disposed between the first fixing member 110 and the second fixing member 120, and is used to push at least some of the teeth off the rack belt. It should be explained that the first fixing member 110 and the second fixing member 120 can fix the rack belt, and then the pusher removes the teeth from the rack belt. Understandably, in actual production, this allows for the removal of teeth without damaging the rack belt, thereby improving the yield rate of zipper processing.

[0050] Currently, excess teeth are mostly removed manually by cutting with a knife, which can easily damage the rack and generate a large amount of shavings during the process. However, in this application, a tooth-pushing component is provided, at least partially positioned between the first fixing member 110 and the second fixing member 120, to push at least some of the teeth off the rack. On the one hand, the tooth-pushing component does not cut the rack during the pushing process, which helps improve the processing yield; on the other hand, the tooth-pushing component can push out the complete rack, which reduces the generation of shavings and improves the processing environment.

[0051] In some embodiments of this application, please refer to Figures 2 to 4 , Figure 2 This embodiment provides the following: Figure 1 A partial schematic diagram of structure A; Figure 3 A schematic diagram of the tooth-pushing mechanism provided in this embodiment is shown; Figure 4A schematic diagram of the structure of the second fastener 120 provided in this embodiment is shown. The first fastener 110 of this embodiment includes a first boss 111 extending along a direction close to the second fastener 120, and the second fastener 120 includes a second boss 121 extending along a direction close to the first fastener 110. The first boss 111 is configured to cooperate with the second boss 121 to clamp the rack belt. It can be understood that the first boss 111 is close to the second boss 121, or the second boss 121 is close to the first boss 111, or the first boss 111 and the second boss 121 are close to each other to achieve clamping of the rack belt.

[0052] The first boss 111 includes a first hollow portion 114, which is used to avoid the teeth; and / or, the second boss 121 includes a second hollow portion, which is also used to avoid the teeth. It should be explained that, since the rack band is typically thinner than the teeth, the first hollow portion 114 and / or the second hollow portion can avoid the teeth and protect them during the tooth-pushing process.

[0053] Please refer to the embodiments described in this application. Figure 4 And see Figure 5 , Figure 5 This embodiment provides the following: Figure 3 A partial enlarged structural diagram of section B is shown. In this embodiment, the first boss 111 includes a first protrusion structure 112 and a second protrusion structure 113, with a first hollow portion 114 disposed between the first protrusion structure 112 and the second protrusion structure 113. The second boss 121 has a top surface 122 and at least one side surface 123. The top surface 122 is disposed opposite to the first protrusion structure 112, and the second protrusion structure 113 extends to one side of the side surface 123 and abuts against it.

[0054] It should be explained that during the pushing process of the tooth pusher, there is a certain bonding force between the first tooth to be pushed away and the second tooth to be retained. The second protrusion structure 113 can block the second tooth in the direction in which the pusher 200 pushes the first tooth, so as to prevent the second tooth from being pushed away by the first tooth.

[0055] Please refer to the embodiments described in this application. Figure 5 In this embodiment, the first hollow portion 114 has a first inner wall 116 for avoiding teeth, and the first inner wall 116 has a curved structure. And / or, the second hollow portion has a second inner wall for avoiding teeth, and the second inner wall has a curved structure. It should be explained that by setting the first inner wall 116 and / or the second inner wall to a curved structure, it is beneficial to further protect the teeth. In some embodiments, the first inner wall 116 and / or the second inner wall has an arcuate structure.

[0056] Please refer to the embodiments described in this application. Figure 2 and Figure 4 In this embodiment, there are at least two first protrusions 111, which are spaced apart and a first gap 115 is formed between them; and / or, there are at least two second protrusions 121, which are spaced apart and a second gap 124 is formed between them. It is understood that at least two first protrusions 111 and at least two second protrusions 121 can enhance the clamping effect on the rack belt, thereby improving the tooth pushing yield.

[0057] The pusher is provided with a third protrusion 210, which is configured to pass through the first gap 115 and / or the second gap 124 to push the tooth. It should be explained that the first protrusion 111 and the second protrusion 121 are positioned directly opposite the tooth gap between two adjacent teeth, ensuring that each protrusion corresponds exactly to one tooth, thereby improving the uniformity of force distribution on the teeth. Furthermore, the first gap 115 and the second gap 124 serve to avoid the third protrusion 210, allowing it to pass through the first fixing member 110 and / or the second fixing member 120 to push the tooth.

[0058] Please refer to the embodiments described in this application. Figure 1 In this embodiment, the pusher moves along a first direction a to push the tooth; wherein, the first direction a is perpendicular to the second direction b, and the second direction b is the direction in which the first fixing member 110 and / or the second fixing member 120 press against the rack belt. It should be explained that the first direction a can be the depth direction of the groove on the tooth, and pushing the tooth off the rack belt along the first direction a makes it easier.

[0059] It needs to be explained that, Figure 1 The first direction 'a' in the diagram refers only to the direction in which the first fixing member 110 presses against the rack belt. The direction in which the second fixing member 120 presses against the rack belt is opposite to the direction in which the first fixing member 110 presses against the rack belt.

[0060] Please refer to the embodiments described in this application. Figure 1 The tooth-pushing mechanism of this embodiment includes a pusher 200, which extends along a second direction b; wherein the pusher 200 has at least a partially tapered structure along the second direction b, so that when the pusher 200 moves along the second direction b, it pushes the tooth-pushing member to move along the first direction a.

[0061] It should be explained that the pusher 200 has at least a partially tapered structure along the second direction b, which is a slope structure. As the pusher 200 moves along the second direction b, the tapered structure gradually pushes the pusher tooth to move along the first direction a.

[0062] In some embodiments, the pusher is provided with a rotating shaft, and a roller 220 is provided on the rotating shaft. The roller 220 is slidably connected with the pusher 200, which can help reduce the frictional resistance between the pusher 200 and the pusher, thereby improving the transmission efficiency of the pushing force in the pusher mechanism.

[0063] In order to better implement the tooth-pushing mechanism in this application, based on the tooth-pushing mechanism provided in any of the above embodiments, this application also provides a zipper processing device, including the tooth-pushing mechanism described above, which is used to push away at least some of the teeth on the toothed belt.

[0064] In some embodiments of this application, please refer to Figure 6 and Figure 7 , Figure 6 A schematic diagram of the zipper processing device provided in this embodiment is shown. Figure 7 An exploded view of the zipper processing apparatus provided in this embodiment is shown. In this embodiment, there are at least two pusher mechanisms, which are arranged opposite to each other to process at least two toothed strips.

[0065] It should be explained that zippers typically have a left toothed strip and a right toothed strip. The zipper processing device of this embodiment can process both the left and right toothed strips, thereby improving the processing efficiency of zippers.

[0066] Please refer to the embodiments described in this application. Figure 7 The zipper processing device in this embodiment includes a push cylinder and a pusher mechanism including a pusher 200. The push cylinder connects the pusher 200 and the first fixing member 110 to push the pusher 200 and the first fixing member 110 to move along the second direction b.

[0067] It should be explained that the push cylinder serves as a power source, which drives the pusher 200 and the first fixed member 110 to move through the same power source, thereby enabling the pusher 200 and the first fixed member 110 to move in tandem, thus improving the fault tolerance of the zipper processing device.

[0068] In some embodiments, the push cylinder includes a push plate and a push frame 600, with the push member 200 fixed on the push plate and the first fixing member 110 fixed on the push frame 600.

[0069] In some embodiments, the zipper processing device includes a base 700 and a second fastener 120 disposed on the base 700.

[0070] In some embodiments of this application, the zipper processing apparatus further includes a positioning mechanism 500, which includes a positioning track 520 and a positioning disk 510. The positioning disk 510 is perpendicular to the positioning track 520 and has a plurality of positioning teeth. The positioning disk 510 is configured to rotate to count the number of teeth on the zipper on the positioning track 520.

[0071] It needs to be explained that the positioning teeth can be inserted into the gap between two adjacent teeth.

[0072] In some embodiments, the tooth-pushing mechanism includes a housing 800, on which a tooth-pushing track 810 is provided, and a rack belt can perform tooth-pushing steps on the tooth-pushing track 810. The tooth-pushing track 810 is connected to a positioning track 520, and the rack belt can move along a third direction c on the tooth-pushing track 810 and the positioning track 520.
