Abstract
Description
Technical Field
[0001] This utility model relates to the field of zipper head assembly technology, and more specifically, it relates to a push device for automatically clamping, unlocking and holding a spring-loaded zipper head. Background Technology
[0002] Currently, in conventional zipper pull processing, a vibratory feeder is typically used to guide the zipper pull tabs onto a guide rail. The tabs need to be pushed open to 90 degrees by a cylinder to unlock the zipper pull and facilitate the subsequent threading of the zipper tape. However, in actual operation, due to various vibrations and equipment operation, the tabs are prone to tipping over due to unstable angles, causing them to jam during threading. This leads to equipment malfunctions and severely impacts production efficiency and product quality.
[0003] In traditional production methods, the pullers are guided onto the guide rails via a vibratory feeder, and the opening of the pullers relies on a cylinder to push them open. However, due to various vibrations and operational factors during machine operation, the pullers may detach and return to their initial state, causing equipment malfunctions and affecting the stability of the entire production process.
[0004] To address the aforementioned problems, this invention proposes a novel solution: a mechanical gripper directly grasps the zipper pull, then transfers it from the vibratory feeder to a pushing device. Under the action of a cylinder, the pushing device smoothly rotates the zipper pull from a vertical to a horizontal position. During this process, a mechanical cam mechanism automatically opens the zipper tab to 90 degrees and maintains this position. This design not only improves the accuracy of the zipper pull entering the zipper belt but also effectively avoids mechanical failures caused by vibration, thereby improving production efficiency and product quality.

The pull tab opening module has an opening plate. The pull tab clamping module includes a clamping groove b that is adapted to the shape of the pull tab. The clamping groove b is used to vertically insert the pull tab from above. The opening plate is located below the clamping groove and interferes with the pull tab. When the flipping module drives the pull tab clamping module to flip, the flipping module pulls the pull tab clamping module to flip vertically. Under the interference of the opening plate, the pull tab and the pull tab are pulled apart to form a 90° angle and held in this state.
[0008] According to one embodiment of the present invention, the flipping module includes a fixed base connected to a pusher base, a flipping base rotatably connected to the top of the fixed base, a first telescopic device fixedly connected to the bottom of the fixed base, a drive end of the first telescopic device extending from the fixed base and eccentrically rotatably connected to the flipping base, a flipping head mounted on the flipping base, and a flipping pressure block mounted on the flipping head; a first bracket of T-shaped structure is connected to the pusher base, a third track is mounted on the vertical arm of the first bracket, a third slider is slidably connected on the third track, a pressed seat is fixed on the third slider, and a second bracket for mounting a sliding plate is provided on the side of the pressed seat away from the third slider.
[0009] According to one embodiment of the present invention, a roller seat is installed at the top of the pressed seat, a guide wheel is installed on the roller seat, a cam surface a is provided on the flipping pressing block to match the guide wheel, a fourth connecting post is also provided on the pressed seat, a second connecting post is provided on the side of the flipping pressing block, and a second tension spring is sleeved between the second connecting post and the fourth connecting post.
[0010] According to the above embodiments, this utility model also provides a pusher device for automatically clamping, unlocking, and holding a spring-loaded pull head. The pusher seat is provided with a matching second slider and a second track. The second slider is fixedly connected to the upper end face of the pusher seat. The horizontal arm of the first bracket is fixedly connected to one end of the second track. A connecting block is connected to the other end of the second track. A stop seat is fixed on the pusher seat. The stop seat is located on the side of the flipping module away from the pull head module. A first buffer head that abuts against the connecting block is connected to the stop seat. A third connecting post is provided on the flipping seat. A first connecting post is also provided on the connecting block. A third tension spring is sleeved between the first connecting post and the third connecting post.
[0011] According to one embodiment of the present invention, the clamping head module includes a first clamping arm and a second clamping arm fixedly connected to the flipping pressure block. The bottom of the second clamping arm is rotatably connected to the first clamping arm through a rotating shaft. The end faces of the first and second clamping arms away from the rotating shaft are connected by a first tension spring. The first clamping arm is provided with a first clamping part, and the second clamping arm is provided with a second clamping part. The first clamping part and the second clamping part form a clamping groove b and automatically clamp the pull head through the first tension spring.
[0012] According to one embodiment of the present invention, a base is provided at one end of the first track, the second telescopic device is installed on the base, and a second buffer head is also installed on the base, the second buffer head abutting against the push seat.
[0013] According to one embodiment of the present invention, the top of the slitting plate is set higher than the guide wheel, and when the clamping head module is flipped to a horizontal state, the top of the slitting plate is set lower than the first clamping arm or the second clamping arm.
[0014] In summary, this application includes at least one of the following beneficial technical effects:
[0015] 1. In this solution, the slider is rotated from a vertical to a horizontal state by a flipping module. Specifically, the first telescopic device drives the flipping pressure block to adjust the slider's posture to a horizontal state. The vertically arranged opening plate interferes with the slider. When the slider is flipped to a horizontal state, the slider is automatically opened to 90 degrees during the flipping process, achieving stable unlocking of the slider. The slider is fixed in position by the slider clamping module to prevent the slider from springing back in subsequent processes, thereby ensuring the stability and high efficiency of the entire production process.
[0016] 2. In this solution, the pull tab opening module ensures that the pull head and pull tab are in the open state in a vertical position through the opening plate, thereby facilitating the feeding of the pull head; the pull head clamping module clamps the pull head through the first clamping arm and the second clamping arm in conjunction with the first tension spring, realizing the automatic clamping function of the pull head and ensuring the stability and flexibility of clamping.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] like Figure 1 As shown, this utility model provides a pusher device for automatically clamping, unlocking, and holding a spring-loaded pull tab, including a support module 1, a flipping module 2, a pusher module 3, a pull tab module 4, and a pull tab clamping module 5. The flipping module 2, the pull tab module 4, and the pull tab clamping module 5 are all mounted on the support module 1. Furthermore, the pusher module 3 can drive the flipping module 2, the pull tab module 4, and the pull tab clamping module 5 to move synchronously.
[0028] Furthermore, such as Figure 2As shown, the support module 1 has a first track 101, on which a first slider 102 is slidably connected. A pusher seat 103 is fixedly mounted on the first slider 102. The pusher module 3 includes a second telescopic member 302. The driving end of the second telescopic member 302 is fixedly connected to the pusher seat 103 to push the pusher seat 103 to move along the first track 101. A flipping module 2 and a pull tab opening module 4 are mounted on the pusher seat 103. A pull tab clamping head module 5 is also connected to the flipping end of the flipping module 2. The pull tab opening module 4 has a tab opening plate 408. The pull tab clamping head module 5 includes a clamping groove b that is adapted to the shape of the pull tab. The clamping groove b is an open opening facing upwards. The pull tab can be clamped from the vibratory feeder by a mechanical gripper, and then the pull tab is vertically inserted from above the clamping groove b. For details, please refer to [reference needed]. Figure 1 At the location of the central pull head, since the sliding plate 408 is located below the clamping groove and interferes with the pull tab, when the flipping module 2 drives the clamping pull head module 5 to flip, the flipping module 2 pulls the clamping pull head module 5 to flip vertically. Under the interference of the sliding plate 408, that is, the flipping module 2 flips the pull head to a horizontal state. At the same time, the flipping module 2 also pulls the pull head away from the pull tab, so that the pull tab and the sliding plate 408 resist each other, so that the pull head and the pull tab unlock in a vertical state, and the clamping pull head module 5 and the sliding plate 408 keep the pull head and the pull tab unlocked in this state.
[0029] like Figure 3As shown, the flipping module 2 includes a fixed base 202 connected to the push base 103. The top of the fixed base 202 is rotatably connected to the flipping base 203, and the bottom end of the fixed base 202 is fixedly connected to a first telescopic device 201. The driving end of the first telescopic device 201 extends from the fixed base 202 and is eccentrically rotatably connected to the flipping base 203. A flipping head 204 is installed on the flipping base 203, and a flipping pressure block 205 is also installed on the flipping head 204. A T-shaped first bracket 401 is connected to the push base 103, and a third track 402 is installed on the vertical arm of the first bracket 401. The third track 402 slides on the third track 402. A third slider 403 is connected, and a pressing seat 404 is fixed on the third slider 403. A second bracket 407 for mounting a slitting plate 408 is provided on the side of the pressing seat 404 away from the third slider 403. A roller seat 405 is mounted on the top of the pressing seat 404, and a guide wheel 406 is mounted on the roller seat 405. A cam surface a is provided on the flipping pressing block 205, which is adapted to the guide wheel 406. A fourth connecting post 409 is also provided on the pressing seat 404. A second connecting post 206 is provided on the side of the flipping pressing block 205, and a second tension spring 7 is sleeved between the second connecting post 206 and the fourth connecting post 409. The fixed seat 202 supports the entire flipping module 2 and is connected to the push seat 103 to ensure the stability of the module during operation. The flipping seat 203 can rotate on the fixed seat 202, driven by power provided by the first telescopic device 201, to achieve a flipping action, thereby adjusting the posture of the workpiece being processed. The eccentric connection between the drive end of the first telescopic device 201 and the flipping seat 203 makes the flipping smoother and more flexible. The flipping head 204 and the flipping pressure block 205 further ensure the precise position and stability of the workpiece during the flipping process. The pusher seat 103 achieves precise positional movement through the third track 402 and the third slider 403 on the first bracket 401, ensuring accurate positioning of the workpiece between different processes. The second bracket 407 is used to install the slitting plate 408 for operation on the workpiece in specific steps. The working principle is as follows: the telescopic movement of the first telescopic device 201 drives the flipping seat 203 to rotate, realizing the pressing or releasing of the slitting plate 408 by the flipping head 204 and the flipping pressure block 205 on it; the cooperation of the third track 402 and the third slider 403 allows the pressed seat 404 to move smoothly along the track, realizing the adjustment of the position of the slitting plate 408; the matching design of the guide wheel 406 and the cam surface a ensures the smoothness of the pressing and releasing actions.
[0030] Furthermore, the roller seat 405 and guide wheel 406 mounted on the top of the pressure seat 404 can guide the tilting pressure block 205 to move smoothly up and down. The cam surface a on the tilting pressure block 205 cooperates with the guide wheel 406, so that the tilting pressure block 205 can not only tilt along a specified path, but also precisely control the tilting angle. The fourth connecting post 409 on the pressure seat 404 and the second connecting post 206 on the side of the tilting pressure block 205 are connected by a second tension spring 7. The tension of the second tension spring 7 drives the tilting pressure block 205 to return to its initial position. Through this design, the tilting pressure block 205 can be tilted to a specified position for operation under pressure, and automatically return to its original position after the external force is removed by the action of the second tension spring 7, realizing automation and precise control.
[0031] like Figure 1 , 4 As shown in Figure 5, a roller seat 405 is mounted on the top of the pressing seat 404, and a guide wheel 406 is mounted on the roller seat 405. The flipping pressing block 205 has a cam surface a that matches the guide wheel 406. The pressing seat 404 also has a fourth connecting post 409, and a second connecting post 206 is provided on the side of the flipping pressing block 205. A second tension spring 7 is sleeved between the second connecting post 206 and the fourth connecting post 409. The guide wheel 406 mounted on the roller seat 405 reduces the frictional resistance during the movement of the flipping pressing block 205, making the flipping smoother. The cam surface a on the flipping pressing block 205 cooperates with the guide wheel 406 to ensure that the flipping pressing block 205 can accurately flip along a predetermined path.
[0032] The fourth connecting post 409 is connected to the second connecting post 206 on the side of the flipping pressure block 205 via a second tension spring 7. During the flipping process, the second tension spring 7 generates tension and compression, providing a return force that allows the flipping pressure block 205 to reset. Specifically, the flipping pressure block 205 flips along a predetermined path via the cooperation of the cam surface a and the guide wheel 406. The second tension spring 7 provides a return force, so that when the flipping head 204 returns to its initial state, the second tension spring 7 can drive the pressed seat 404 back to its original position, allowing for the next unlocking action of the pull head.
[0033] Furthermore, such as Figure 2As shown, the pusher seat 103 is provided with a matching second slider 105 and a second track 106. The second slider 105 is fixedly connected to the upper end face of the pusher seat 103. The horizontal arm of the first bracket 401 is fixedly connected to one end of the second track 106. A connecting block 107 is connected to the other end of the second track 106. A stop seat 104 is fixed on the pusher seat 103. The stop seat 104 is located on the side of the flipping module 2 away from the clamping head module 5. A first buffer head 108 that abuts against the connecting block 107 is connected to the stop seat 104. A third connecting post 207 is provided on the flipping seat 203. A first connecting post 109 is also provided on the connecting block 107. A third tension spring 8 is sleeved between the first connecting post 109 and the third connecting post 207. The pusher seat 103 provides a smooth platform for pushing objects. The second slider 105 is fixedly connected to the pusher seat 103 to ensure smooth movement. The horizontal arm of the first bracket 401 is fixed to one end of the second track 106, providing a support and guiding structure. The other end of the second track 106 is fixed by the connecting block 107, ensuring the stability of the overall structure and facilitating the transmission of thrust. The anti-reverse seat 104 is fixed to one side of the pusher seat 103 to prevent over-push. Its first buffer head 108 abuts against the connecting block 107, effectively buffering the impact during the push process. During the push process, the cooperation of the connecting block 107 and the connecting column, as well as the tension of the third tension spring 8, allows the pusher seat 103 to move smoothly along the second track 106. The anti-reverse seat 104, through the action of the first buffer head 108, further ensures the safety and smoothness of the operation, preventing excessive movement during the push process, thereby ensuring precise control of the process and safe operation of the equipment.
[0034] Furthermore, during the feeding process of the zipper head, the zipper head is usually clamped by the feeding mold for threading the zipper tape. Therefore, by pushing one end of the second bracket 407, the second bracket 407 together with the opening plate 408 can be moved away, thereby exposing the zipper tab in the vertical unlocking state, which makes it easier for the feeding mold to clamp the zipper head and the zipper tab. Then, through the connection of the third tension spring 8, the second bracket 407 can be quickly reset after being moved away, which is convenient for the next use of the opening plate 408.
[0035] like Figure 6As shown, the zipper puller module 5 includes a first clamping arm 501 and a second clamping arm 502 fixedly connected to the flipping pressure block 205. The bottom of the second clamping arm 502 is rotatably connected to the first clamping arm 501 via a rotating shaft 503. The end faces of the first clamping arm 501 and the second clamping arm 502 away from the rotating shaft 503 are connected by a first tension spring 6. The first clamping arm 501 is provided with a first clamping part 5011, and the second clamping arm 502 is provided with a second clamping part 5021. The first clamping part 5011 and the second clamping part 5021 form a clamping groove b and automatically clamp the zipper puller through the first tension spring 6. In this zipper puller module 5, the first clamping arm 501 is responsible for providing the main clamping force and is connected to the second clamping arm 502 through the first tension spring 6 to ensure the stability of the clamping action and the automatic clamping effect. The second clamping arm 502 is connected to the first clamping arm 501 via a rotating shaft 503. It can flip or rotate under specific actions to adjust the clamping position or release the clamped object. A flipping pressure block 205 is fixedly connected to its bottom to increase flexibility and adaptability during clamping. A first tension spring 6 is provided on the end face of the first clamping arm 501 and the second clamping arm 502 away from the rotating shaft 503, automatically clamping the slider head through elastic restoring force. The first clamping part 5011 on the first clamping arm 501 and the second clamping part 5021 on the second clamping arm 502 work together to form a stable clamping groove, achieving effective clamping of the slider head. In terms of working principle, when the slider head is inserted into the clamping groove b, the slider head first pushes open the first clamping arm 501 and the second clamping arm 502 on both sides. Then, due to the action of the tension spring, the first clamping arm 501 and the second clamping arm 502 automatically move towards the slider head and clamp it, ensuring the flexibility and stability of the clamping process.
[0036] A base 301 is provided at one end of the first track 101. A second telescopic device 302 is mounted on the base 301, and a second buffer head 303 is also mounted on the base 301, abutting against the push seat 103. The top of the slitting plate 408 is higher than the guide wheel 406. When the clamping head module 5 is flipped to a horizontal state, the top of the slitting plate 408 is lower than the first clamping arm 501 or the second clamping arm 502. The base 301 is responsible for supporting the second telescopic device 302 and providing a stable foundation to ensure that the movement of the telescopic device can be accurate and reliable. The second telescopic device 302 is mounted on the base 301 and can move in a set direction. The second buffer head 303 can absorb the force and rebound force of the second telescopic device 302, effectively reducing vibration and impact and protecting other components from damage. The pusher seat 103 is connected to the second buffer head 303 and can perform push-pull movements through the action of the second telescopic device 302 to push or pull other components. The height setting of the top of the slitting plate 408 ensures that when the clamping head module 5 is flipped to a horizontal state, the top of the slitting plate 408 is lower than the first or second clamping arm 502. This effectively prevents interference between the slitting plate 408 and the clamping arm during clamping or processing, ensuring smooth operation. The movement of the second telescopic device 302 drives the second buffer head 303 and the pusher seat 103 to perform push-pull movements, while ensuring that the slitting plate 408 of the clamping head module 5 does not interfere with the clamping arm under specific working conditions, thereby achieving stable clamping and movement of the clamping head.
[0037] It should be noted that both the first telescopic device 201 and the second telescopic device 302 of this utility model are cylinders.
[0038] The specific working principle is: combining Figure 7 As shown, a mechanical gripper directly picks up the zipper pull from the vibratory feeder, and a cylinder in the pushing device pushes it to rotate it from a vertical to a horizontal position. During rotation, the cam surface a of the flip-over pressure block 205 further ensures that the zipper pull is automatically opened and maintained at 90 degrees. This device not only improves operational stability and reduces equipment failures caused by unstable zipper pull angles, but also ensures that the zipper pull remains in the correct open position throughout the production process, thereby avoiding damage to the zipper pull, zipper tape, and other components, significantly improving production efficiency and product quality.
[0039] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
