Description

Technical Field

[0001] This utility model relates to the field of zipper production equipment technology, and in particular to a zipper assembly machine. Background Technology

[0002] A zipper is a connector that uses continuously arranged teeth to interlock or separate to achieve the function of opening and closing. It is widely used in clothing, bags and other items.

[0003] Under current conditions, a zipper production device, such as the one disclosed in CN220013009U, is commonly used. This device includes a cutting device on the sewing table, and both the sewing and cutting devices are controlled by a control element. The control element controls the cutting device to cut the zipper chain after the sewing device has sewn a set number of stitches. However, this device relies solely on the conveyor groove of the lower pressure plate to limit the zipper chain, and the cutting device is located close to the feeding mechanism. During chain cutting, the chain is prone to shifting or loosening, resulting in uneven cuts, burrs, or damage to the chain teeth, affecting the product qualification rate. After completing one segment of zipper production, the chain conveying needs to be restarted manually or by external control before the next segment can begin. Manual intervention is required after each chain cut, failing to meet the requirements for continuous automated production. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing zipper production equipment cannot achieve continuous automated feeding during cutting, and to propose a zipper assembly machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A zipper assembly machine includes a workbench, on which a chain feeding device, a cutting device, a sewing device, and a collecting device are arranged. A conveyor platform corresponding to the cutting device is also arranged on the workbench, and an alternating feeding mechanism for automatically feeding zippers is provided on the conveyor platform. The alternating feeding mechanism includes two sets of limiting frames for limiting the chain, and a support plate for supporting the chain is fixedly installed on the limiting frame. An electric telescopic rod is fixedly installed on the limiting frame, and a limiting plate corresponding to the support plate and used for vertically limiting the chain is fixedly installed at the output end of the electric telescopic rod.

[0007] Preferably, the alternating feeding mechanism further includes a rotating rod rotatably mounted on the conveyor table, and a gear is keyed to the rotating rod. Two fixed frames are fixedly mounted on the conveyor table, and two racks, rack one and rack two, are slidably sleeved on the fixed frames and mesh with the gear.

[0008] The rack one and rack two are respectively fixedly installed with support blocks that pass through the conveyor table, and a movable frame is fixedly installed on the support block. The movable frame is slidably provided with a conveyor frame that moves alternately laterally, and the limiting frame is provided on the conveyor frame.

[0009] Preferably, a limiting block for limiting the movement of rack one and rack two is fixedly installed on the fixing frame, and the limiting block has a T-shaped structure.

[0010] Preferably, a slide rod is fixedly installed inside the movable frame, and a movable block integrally connected to the conveyor frame is slidably sleeved on the slide rod.

[0011] Preferably, the conveyor platform is provided with a limiting hole for controlling the movement trajectory of the conveyor frame, a limiting rod extending toward the limiting hole is fixedly installed on the conveyor frame, and a circular slider that fits into the limiting hole is fixedly installed on the limiting rod.

[0012] Preferably, the middle section of the limiting hole is offset from both ends, and the corner of the limiting hole has an arc-shaped structure adapted to the circular slider.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This utility model, through the coordinated clamping of two sets of limiting plates and support plates, can firmly fix both ends of the zipper when the cutting device cuts the zipper, effectively avoiding problems such as skewed cuts caused by material loosening, thereby ensuring the flatness and precision of the cut surface, which helps to improve the cutting quality and product qualification rate of the zipper.

[0015] 2. This utility model, through precise control of the electric telescopic rod, can quickly release the limit on the cut chain, allowing it to smoothly enter the sewing process. At the same time, the alternating feeding mechanism driven by the servo motor, through gear and rack transmission and guide by the limit hole of a specific trajectory, ensures that the two sets of conveyor frames can move towards each other synchronously and without interference, thereby accurately pulling the chain to be cut to the cutting station, which helps to improve the working efficiency of the equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A zipper assembly machine includes a workbench 1, a controller mounted on the workbench 1, a chain feeding device 2, a cutting device 4, a sewing device 5, and a collecting device 6 mounted on the workbench 1. A conveyor platform 3 corresponding to the cutting device 4 is mounted on the workbench 1, and an alternating feeding mechanism for automatically conveying zippers is mounted on the conveyor platform 3. The alternating feeding mechanism achieves stable conveying and precise positioning of the zipper chain, which not only ensures cutting quality but also helps to improve the working efficiency of the equipment.

[0024] The alternating feeding mechanism includes two sets of limiting frames 21 for limiting the chain. The two sets of limiting frames 21 are respectively set on both sides of the conveyor table 3 corresponding to the cutting device 4, so as to limit and fix the zipper from both ends.

[0025] A support plate 24 for supporting the chain is fixedly installed on the limiting frame 21. An electric telescopic rod 22 is fixedly installed on the limiting frame 21, and a limiting plate 23 corresponding to the support plate 24 and used to vertically limit the chain is fixedly installed at the output end of the electric telescopic rod 22. The limiting plate 23 is horizontally set and located directly above the support plate 24. When the electric telescopic rod 22 extends or retracts, it drives the limiting plate 23 to move up and down, thereby clamping and releasing the zipper chain on the support plate 24.

[0026] The alternating feeding mechanism also includes a rotating rod 7 rotatably mounted on the conveyor table 3. A servo motor that drives the rotating rod 7 to rotate is fixedly mounted on the conveyor table 3, and a gear 8 is keyed to the rotating rod 7. Two fixed frames 9 are fixedly mounted on the conveyor table 3, and two racks 10 and 11 that mesh with the gear 8 are slidably sleeved on the fixed frames 9.

[0027] A support block 13 that passes through the conveyor table 3 is fixedly installed on rack 10 and rack 2 respectively, and a movable frame 14 is fixedly installed on the support block 13. A conveyor frame 17 that moves alternately laterally is slidably arranged on the movable frame 14, and a limit frame 21 is arranged on the conveyor frame 17.

[0028] A limiting block 12 for limiting rack 10 and rack 2 11 is fixedly installed on the fixed frame 9. The limiting block 12 has a T-shaped structure. The T-shaped limiting block 12 can limit rack 10 and rack 2 11 from the upper and lower directions to prevent rack 10 and rack 2 11 from shifting up and down or falling off the fixed frame 9 during sliding, and ensure that rack 10 and rack 2 11 always maintain a stable sliding state.

[0029] A slide rod 15 is fixedly installed inside the movable frame 14, and a movable block 16 integrally connected to the conveyor frame 17 is slidably sleeved on the slide rod 15. Through the cooperation of the slide rod 15 and the movable block 16, the sliding of the conveyor frame 17 on the movable frame 14 is guided, ensuring that the conveyor frame 17 can move smoothly in a fixed direction.

[0030] The conveyor table 3 is provided with a limiting hole 18 for controlling the movement trajectory of the conveyor frame 17. A limiting rod 19 extending into the limiting hole 18 is fixedly installed on the conveyor frame 17, and a circular slider 20 that fits into the limiting hole 18 is fixedly installed on the limiting rod 19. The diameter of the circular slider 20 is adapted to the width of the limiting hole 18, and it can slide freely in the limiting hole 18 and fit tightly against the inner wall of the limiting hole 18 to prevent the limiting rod 19 from shaking in the limiting hole 18.

[0031] The middle section and both ends of the limiting hole 18 are offset. The limiting hole 18 cooperates with the circular slider 20 to precisely control the movement trajectory of the conveyor frame 17, so that the two sets of conveyor frames 17 are offset during the process of moving towards each other, avoiding movement interference between the two sets of limiting frames 21, and ensuring that the alternating feeding mechanism can operate in an orderly manner.

[0032] The corner of the limiting hole 18 is an arc-shaped structure that matches the circular slider 20. The arc-shaped structure design enables the circular slider 20 to smoothly turn when passing through the corner of the limiting hole 18, avoiding jamming or impact.

[0033] It should be noted that the specific models and specifications of the controller, servo motor, feeding device 2, cutting device 4, sewing device 5, and collecting device 6 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation methods adopt existing technology in this field, so they will not be elaborated here.

[0034] The functional principle of this utility model can be explained through the following operation methods:

[0035] The controller controls the chain feeding device 2, cutting device 4, sewing device 5, and collecting device 6 to start sequentially, adjusts them to appropriate working parameters, and then controls the servo motor to start.

[0036] The chain feeding device 2 transports the zipper to the alternating feeding mechanism on the conveyor table 3. At this time, the electric telescopic rods 22 on both sets of conveyor frames 17 are in a retracted state. The output end of the electric telescopic rod 22 drives the limiting plate 23 to move down and cooperate with the support plate 24 on the limiting frame 21 to limit and clamp the chain in the vertical direction, ensuring that the chain is in a stable tension state before cutting.

[0037] When the chain is conveyed to the designated cutting position, the cutting device 4 is started to cut the chain between the two sets of limit frames 21. During this process, due to the clamping effect of the limit plate 23 and the support plate 24, the zipper is always kept taut to ensure the cutting quality.

[0038] After the cutting is completed, the electric telescopic rod 22 on the side near the sewing device 5 retracts, driving the corresponding limiting plate 23 to move upward, releasing the limitation on the chain on that side, and the cut chain enters the processing area of ​​the sewing device 5 under the traction of the subsequent mechanism;

[0039] At the same time, the output end of the servo motor drives the rotating rod 7 to rotate, and the rotating rod 7 drives the gear 8 to rotate synchronously. The gear 8 drives the rack 10 and rack 21 on the two sets of fixed frames 9 to move in opposite directions through the meshing connection of rack 10 and rack 21.

[0040] The support blocks 13 on rack 10 and rack 2 11 move synchronously. The support blocks 13 drive the moving frame 14 to move towards each other. The moving frame 14 drives the conveyor frame 17 to move synchronously through the moving block 16.

[0041] When the conveyor frame 17 moves, the limiting rod 19 fixedly installed at its bottom drives the circular slider 20 to slide in the limiting hole 18. Since the middle section of the limiting hole 18 is offset from both ends and the corner is an arc structure, the limiting frames 21 on the two sets of conveyor frames 17 are offset during the process of moving towards each other, so as to avoid the two sets of limiting frames 21 from interfering with each other.

[0042] During the movement of the two sets of limiting frames 21, the chain feeding device 2 feeds materials synchronously, conveying new chain segments to the space between the two sets of limiting frames 21. The electric telescopic rod 22 on the side away from the sewing device 5 extends to limit the chain on that side, completing one cycle of feeding.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
