Description

Technical Field

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

[0002] Zipper tooth assembly refers to the automated process of sequentially installing individual zipper teeth onto the edge of the zipper belt. Typically, a feeding mechanism conveys the zipper belt and teeth to the assembly area, where a positioning structure precisely aligns them. A pressing mechanism then secures the teeth to the zipper belt, forming a complete, equidistant zipper chain. This process emphasizes high-precision positioning and stable pressing, and is widely used in the production of various types of zippers, including nylon, resin, and metal zippers.

[0003] Existing zipper toothing assembly machines (Announcement No.: CN216089219U) have at least the following drawbacks: In existing technology, zipper toothing assembly devices typically use a fixed speed and fixed path to transport the zipper belt, without a dedicated mechanism for adjusting the belt tension. This structural design makes the zipper belt prone to uneven tension during actual operation due to slack or overstretching. On the one hand, when the belt tension is insufficient, the belt will vibrate and shift when passing through the toothing assembly, resulting in deviations in the tooth installation position and uneven arrangement, and in severe cases, even assembly defects such as missing or crooked teeth. On the other hand, when the tension is too high, the zipper belt is easily stretched and deformed, which affects the pressing accuracy between the teeth and the belt, reducing the consistency and durability of the product. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a zipper teeth assembly device.

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

[0006] A zipper toothing assembly device includes a workbench, a zipper toothing machine for toothing the zipper belt is fixedly connected to the top of the workbench, a feeding frame is fixedly connected to the top of the workbench, a tightening roller is rotatably connected to the top of the workbench via a support plate, a motor is fixedly connected to the side wall of the support plate, the output end of the motor is fixedly connected to the central shaft of the tightening roller, a mounting plate is fixedly connected to the top of the workbench, two guide wheels are rotatably connected to the side wall of the mounting plate, and a tension adjustment mechanism for adjusting the tension of the zipper belt is provided on the side wall of the mounting plate.

[0007] As a further embodiment of this utility model, the tension adjustment mechanism includes a slide rail fixedly connected to the side wall of the mounting plate, a slider slidably connected to the side wall of the slide rail, a threaded rod rotatably connected between the inner walls of the slide rail, one end of the threaded rod penetrating the outer wall of the slide rail and fixedly connected to a rotating wheel, the slider being threadedly connected to the outer wall of the threaded rod, a groove being formed on the side wall of the slider, a movable block being slidably connected inside the groove, a spring being fixedly connected between the opposite surfaces of the movable block and the groove, and an adjusting roller being rotatably connected to the side wall of the movable block.

[0008] As a further embodiment of this utility model, a threaded ring is threadedly connected to the outer wall of one end of the adjusting roller, and a limiting ring for limiting the chain belt is fixedly connected to the side wall of the threaded ring.

[0009] As a further embodiment of this utility model, the side wall of the mounting plate is movably connected to two limiting plates via a connecting plate, and the side walls of the two limiting plates are provided with limiting grooves for the passage of the chain belt.

[0010] As a further embodiment of this invention, the two guide wheels and the adjusting roller are arranged in a triangular pattern.

[0011] As a further embodiment of this utility model, anti-slip grooves are provided on the outer walls of both guide wheels and adjusting rollers.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, a rotating wheel externally mounted on the device drives a threaded rod to rotate, causing the threaded slider to move along the groove direction. This, in turn, drives the movable block to move and changes the position of the adjusting roller, achieving precise adjustment of the chain tension. This solves the problem in existing zipper tooth assembly devices that cannot adjust chain tension, easily leading to chain slack or stretching deformation. When the chain tension is insufficient, adjustment can effectively tighten the chain, preventing it from shaking or shifting during tooth arrangement, and avoiding inaccurate tooth installation, uneven arrangement, or even missing or crooked teeth. When the chain tension is too high, the threaded rod rotates in the opposite direction, causing the slider, movable block, and groove to move in opposite directions. This prevents the chain from breaking due to excessive tension adjustment. The movable block's compression spring provides a buffer, further preventing excessive compression of the chain by the movable block due to excessive adjustment force. This effectively prevents chain breakage, ensures chain operation stability and assembly accuracy, improves tooth arrangement quality and product consistency, and extends the equipment's service life.

[0022] Reference Figures 1-4A zipper toothing assembly device includes a workbench 1, a zipper toothing machine 2 for toothing the zipper belt fixedly connected to the top of the workbench 1, a feed frame 3 fixedly connected to the top of the workbench 1, a tensioning roller 4 rotatably connected to the top of the workbench 1 via a support plate, a motor 5 fixedly connected to the side wall of the support plate, the output end of the motor 5 fixedly connected to the central shaft of the tensioning roller 4, a mounting plate 6 fixedly connected to the top of the workbench 1, two guide wheels 7 rotatably connected to the side wall of the mounting plate 6, a tension adjusting mechanism for adjusting the tension of the zipper belt provided on the side wall of the mounting plate 6, the tension adjusting mechanism including a slide rail 8 fixedly connected to the side wall of the mounting plate 6, a slider 9 slidably connected to the side wall of the slide rail 8, a threaded rod 10 rotatably connected between the inner walls of the slide rail 8, one end of the threaded rod 10 penetrating the outer wall of the slide rail 8 and fixedly connected to a [missing information - likely a component or component]. The rotating wheel 19 and the slider 9 are threadedly connected to the outer wall of the threaded rod 10. The side wall of the slider 9 is provided with a groove 11. The inside of the groove 11 is slidably connected to a movable block 12. A spring 13 is fixedly connected between the opposite surfaces of the movable block 12 and the groove 11. The side wall of the movable block 12 is rotatably connected to an adjusting roller 14. The two guide wheels 7 and the adjusting roller 14 are arranged in a triangle. One end of the outer wall of the adjusting roller 14 is threadedly connected to a threaded ring 15. The side wall of the threaded ring 15 is fixedly connected to a limiting ring 16 for limiting the chain. The side wall of the mounting plate 6 is movably connected to two limiting plates 17 through a connecting plate. The side walls of the two limiting plates 17 are provided with limiting grooves 18 for the passage of the chain. The outer walls of the two guide wheels 7 and the adjusting roller 14 are provided with anti-slip grooves. The anti-slip grooves increase the friction when conveying the chain.

[0023] In this embodiment, the chain belt is first threaded through the internal structure of the zipper toother 2, and then through two guide wheels 7, adjusting roller 14 and limiting groove 18 to form a predetermined conveying path. One end of the chain belt is fixedly connected to the outer wall of the tightening roller 4. The tightening roller 4 is driven to rotate by the motor 5 to realize the winding of the arranged chain belt. After the zipper toother 2 is started, it begins to perform toothing operation on the chain belt. At the same time as the toothing is completed, the tightening roller 4 synchronously drives the chain belt to wind up.

[0024] To achieve precise adjustment of the chain tension, a tension adjustment mechanism is provided: when it is necessary to adjust the chain tension, the operator can rotate the rotating wheel 19 located outside the device, thereby causing the threaded rod 10 to rotate. The threaded rod 10 is threadedly connected to the slider 9. When the threaded rod 10 rotates, it will cause the slider 9 to slide away from the rotating wheel 19. The movement of the slider 9 will simultaneously drive the movable block 12 connected to it to move synchronously, thereby pushing the adjusting roller 14 to move accordingly and tighten the chain, thereby achieving the purpose of tension adjustment.

[0025] In this embodiment, the cooperation between the movable block 12, the slide groove 11, and the spring 13 can play a buffering and limiting role when the chain tension is large, so as to avoid the movable block 12 from excessively squeezing the chain due to excessive adjustment force, thereby effectively preventing the chain from breaking.

[0026] In this embodiment, an adjustable diameter limiting structure is provided on the outer wall of the guide wheel 7 and the adjusting roller 14. By rotating the threaded ring 15, the limiting ring 16 is driven to move on the outer wall of the guide wheel 7 and the adjusting roller 14, thereby adjusting the effective covering diameter of the guide wheel 7 and the adjusting roller 14, realizing the effective limiting of the chain belt running path, and preventing the chain belt from becoming loose or detaching from the guide wheel 7 and the adjusting roller 14 during operation, which would affect the tooth setting accuracy.

[0027] In this embodiment, the chain belt passes through the limiting groove 18 provided with the limiting plate 17 before entering the tooth-laying area. The limiting plate 17 can effectively constrain the vertical direction of the chain belt, thereby preventing the chain belt from floating up and down during the tooth-laying process, ensuring the stability of the chain belt at the tooth-laying position, and further improving the tooth-laying quality and assembly accuracy.

[0028] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: by rotating the threaded rod 10 through the rotating wheel 19 set outside the device, the threaded slider 9 moves along the groove direction, thereby driving the connected movable block 12 to move and changing the position of the adjusting roller 14, thus achieving precise adjustment of the chain tension. This solves the problem in the prior art that the zipper toothing assembly device cannot adjust the chain tension, which easily leads to the chain loosening or stretching deformation. When the chain tension is insufficient, the chain can be effectively tightened by adjustment to prevent the chain from shaking during the toothing process. This mechanism prevents misalignment, uneven tooth placement, and even missing or crooked teeth. When the chain tension is too high, the threaded rod 10 rotates in the opposite direction, causing the slider 9, movable block 12, and slide groove 11 to move in opposite directions. This prevents the chain from breaking due to excessive tension adjustment. The movable block 12 also compresses the spring 13 to buffer the chain, further preventing excessive pressure on the chain due to excessive adjustment force. This effectively prevents chain breakage, ensures chain stability and assembly accuracy, improves tooth alignment quality and product consistency, and extends the service life of the equipment.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
