Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of zipper forming equipment, specifically to a forming tension mechanism for a zipper forming machine, used for tension control and pressing of the zipper chain during the zipper forming process. Background Technology
[0002] In the zipper manufacturing process, especially in the process of processing the raw zipper into a finished zipper, tension control and accurate pressing are crucial steps. Traditional zipper forming equipment is often not precise enough in terms of tension control and cannot automatically adapt to the tension changes of the raw zipper under different production conditions. This can easily lead to unstable zipper forming quality, such as loose zipper teeth, dimensional deviations, and broken raw zippers.
[0003] Therefore, there is a need for a zipper forming tension mechanism that can effectively control tension and achieve high-quality pressing. Summary of the Invention
[0004] The purpose of this invention is to provide a forming tension mechanism for a zipper forming machine that has advantages such as novel structure, precise tension control, good pressing effect, stable guide chain, and convenient installation and maintenance, and can effectively improve the forming quality and production efficiency of zippers, so as to solve the above-mentioned technical problems.
[0005] To achieve the above technical solution, the technical solution of this utility model is as follows: A forming tension mechanism for a zipper forming machine mainly includes a forming tension seat, a self-balancing component, and a pressing component. The forming tension seat serves as the basic support structure of the entire mechanism, with symmetrically arranged first guide wheels on it, and a second guide wheel perpendicularly arranged on one side of the first guide wheel. These guide wheels are used to guide the transmission of the zipper chain. The self-balancing component is movably arranged on the left and right sides of the forming tension seat and located between the first and second guide wheels. It can automatically adjust the tension of the output zipper chain to ensure that the zipper chain maintains appropriate tension throughout the processing. The pressing component is rotatably arranged on the forming tension seat and located below the second guide wheel. Its main function is to press the zipper chains on the left and right sides into a formed zipper.
[0006] Furthermore, the pressing assembly includes a drive motor fixed on the molding tension seat. The output end of the drive motor is provided with a first pressing roller, which is the driving roller for the pressing operation and provides power for the pressing process. A second pressing roller is oscillatingly provided on one side of the first pressing roller. The second pressing roller cooperates with the first pressing roller to complete the pressing of the chain.
[0007] Furthermore, the first pressing roller has a concave pressing groove on its circumference. This groove design better accommodates and positions the chain, preventing it from shifting during pressing. The second pressing roller includes a rocker arm with one end oscillatingly connected to the forming tension seat. The other end of the rocker arm is connected to the forming tension seat via a spring. This spring-connected rocker arm design allows the second pressing roller to oscillate flexibly within a certain range. A second pressing roller is rotatably mounted on the rocker arm. The edge of the second pressing roller is pressed into the pressing groove, and the second pressing roller has a concave V-shaped groove. This V-shaped groove design facilitates better contact and pressing with the chain, while also providing some positioning for the chain during pressing. During pressing, the elastic force of the spring ensures that the second pressing roller always maintains a tight fit with the first pressing roller, adapting to chains of different thicknesses or widths and ensuring uniform and stable pressing force.
[0008] Furthermore, the self-balancing component includes a movable guide shaft fixedly mounted on the side of the forming tension seat, which provides precise guidance for the movement of the counterweight. A square counterweight is fitted onto the movable guide shaft; the shape and weight of the counterweight are designed to automatically adjust its position according to the tension of the chain. A self-balancing guide wheel can be mounted on the counterweight, which contacts the chain to adjust the chain tension by moving the counterweight.
[0009] Furthermore, one side of the counterweight is slidably connected to the other side of the forming tension seat via a linear guide. This linear guide sliding connection ensures the stability and accuracy of the counterweight during movement, reduces the impact of friction on its movement, and enables the counterweight to respond quickly and accurately to changes in the chain tension, thereby achieving automatic adjustment of the chain tension.
[0010] Furthermore, both the first and second guide wheels are installed at the same height, which is beneficial to the stability of the chain during transmission. Both the first and second guide wheels are equipped with guide grooves, which better guide and position the chain, preventing it from detaching from the guide wheels during transmission and ensuring the accuracy and stability of the chain transmission.
[0011] Furthermore, a mounting bracket is installed at an angle on one side of the forming tension seat. The mounting bracket can be used to connect other related equipment or components. At the same time, its inclined design may be to better adapt to the layout and workflow of the entire zipper forming machine, and to facilitate the installation and use of the entire mechanism.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1) The self-balancing component design automatically adjusts the tension of the zipper chain, ensuring that the chain maintains appropriate tension regardless of any tension changes caused by factors during production. This effectively avoids problems such as loose zipper tooth engagement and zipper size deviation caused by improper tension, improving the forming quality of the zipper and ensuring product consistency and stability.
[0014] 2) The special structural design of the first and second pressing rollers in the pressing assembly, as well as their cooperation method, enables high-quality pressing of the zipper chain. The design of the pressing groove and V-groove can accurately position the zipper chain, and the spring-connected second pressing roller can automatically adjust the pressing force according to the actual situation of the zipper chain, ensuring uniform and tight pressing, thereby improving the connection strength and overall performance of the zipper and extending its service life.
[0015] 3) The uniform height installation of the first and second guide rollers, along with the setting of the guide groove, provides a stable transmission path for the zipper chain. The zipper chain can be transmitted smoothly and accurately on the guide rollers, reducing shaking and offset during transmission, improving the stability and efficiency of the entire zipper forming process, and also reducing the defect rate caused by zipper transmission problems.
[0016] 4) The overall forming tension mechanism has a reasonable structural design, and the installation methods of each component are clear and simple, making it convenient to install and debug on the zipper forming machine. At the same time, the maintenance of the mechanism is relatively simple. Through regular inspection, cleaning, and lubrication, problems can be identified and resolved in a timely manner, extending the service life of the mechanism and reducing the operating cost and maintenance difficulty of the equipment.
[0017] In summary, the forming tension mechanism for the zipper forming machine has advantages such as novel structure, precise tension control, good pressing effect, stable chain guide, and convenient installation and maintenance. It can effectively improve the forming quality and production efficiency of zippers and meet the needs of the zipper manufacturing industry. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0021] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0022] Please see the appendix Figure 1 As shown: A forming tension mechanism for a zipper forming machine, the forming tension mechanism comprising:
[0023] A forming tension seat 1 is provided, on which first guide wheels 11 are symmetrically arranged; a second guide wheel 12 is vertically arranged on one side of the first guide wheel 11.
[0024] The self-balancing component 2 is movably disposed on the left and right sides of the forming tension seat 1, and located between the first guide wheel 11 and the second guide wheel 12; it is used to automatically adjust the tension of the output chain; and
[0025] The pressing component 3 is rotatably mounted on the forming tension seat 1 and located below the second guide wheel 11, and is used to press the left and right sides of the zipper into a zipper.
[0026] The self-balancing component is movably positioned on both sides of the forming tension seat, between the first and second guide rollers. Its unique structural design allows it to automatically adjust the tension of the output chain. During zipper production, various factors (such as fluctuations in chain supply speed and changes in material properties) can cause unstable chain tension. This automatic adjustment function ensures that the chain maintains appropriate tension at all times. This is crucial for zipper forming quality, effectively preventing problems such as poor zipper tooth meshing, uneven link spacing, and chain breakage caused by improper tension, greatly improving the quality and consistency of the finished zipper. The movable guide shaft in the self-balancing component provides precise movement guidance for the counterweight. One side of the counterweight is slidably connected to the forming tension seat via a linear guide. This stable connection and guidance method ensures the accuracy and reliability of the counterweight during tension adjustment. The self-balancing guide rollers on the counterweight contact the chain and can make fine adjustments in real time according to the chain's condition, resulting in minimal tension fluctuations throughout the forming process and ensuring the stability and durability of the zipper in long-term use.
[0027] Based on the above embodiments, the pressing assembly 3 includes a drive motor 31 fixed on the forming tension seat 1; the output end of the drive motor 31 is provided with a first pressing roller 32; a second pressing roller 33 is oscillatingly provided on one side of the first pressing roller 32. The drive motor of the pressing assembly 3 drives the first pressing roller to rotate, and the oscillating second pressing roller on one side of the first pressing roller cooperates with it. The second pressing roller is connected to the forming tension seat by a swing arm and a spring. This structure allows the second pressing roller to automatically adjust the pressure according to the thickness and width of the zipper chain. When pressing the zipper chains on the left and right sides, regardless of the slight difference in the size of the zipper chains, the pressing force can be ensured to be uniform, thereby making the connection between the zipper teeth tight and firm, improving the zipper's pulling strength and smoothness, and reducing the possibility of the zipper breaking or jamming during use.
[0028] Based on the above embodiments, the first pressing wheel 32 is provided with a concave pressing groove on its peripheral side;
[0029] The second pressure roller 33 includes a swing arm with one end oscillatingly connected to the forming tension seat 1; the other end of the swing arm is connected to the forming tension seat 1 via a spring; a second pressing roller is rotatably mounted on the swing arm; the edge of the second pressing roller is pressed into a pressing groove; the second pressing roller has a concave V-shaped groove. This embodiment cleverly uses the concave pressing groove on the periphery of the first pressing roller and the concave V-shaped groove on the second pressing roller, which provide precise positioning for the zipper chain during the pressing process. When the zipper chain enters between the pressing rollers, it can be accurately confined within these grooves, preventing offset or misalignment of the zipper chain during pressing, further ensuring the forming quality of the zipper, making the zipper chain more regular in appearance, and meeting the standards of high-quality products.
[0030] Based on the above embodiments, the self-balancing component 2 includes a movable guide optical shaft 21 fixedly installed on the side of the forming tension seat 1; a square counterweight 22 is sleeved on the movable guide optical shaft 21; and a self-balancing guide wheel 23 can be mounted on the counterweight 22. The first guide wheel symmetrically arranged on the forming tension seat and the second guide wheel arranged perpendicular to one side of the first guide wheel are both installed at the same height and both have guide grooves. This design provides a smooth and continuous transmission path for the zipper chain. When the zipper chain runs on the guide wheels, it can smoothly advance along the guide grooves, reducing swaying and friction caused by height differences or lack of guidance, lowering the risk of damage to the zipper chain surface, and also improving the efficiency of zipper chain transmission. This provides a stable input for subsequent tension adjustment and pressing operations, ensuring the smoothness of the entire zipper forming process.
[0031] Based on the above embodiments, one side of the counterweight 22 is slidably connected to one side of the forming tension seat 1 via a linear rail.
[0032] Based on the above embodiments, the first guide wheel 11 and the second guide wheel 12 are both installed at the same height; both the first guide wheel 11 and the second guide wheel 12 are provided with material guide grooves.
[0033] The molding tension seat 1 is mounted with an installation bracket on one side at an angle.
[0034] During installation: First, install the forming tension seat in the corresponding position on the zipper forming machine, ensuring it is securely installed and accurately positioned using bolts or other fixing methods. Then, install the first and second guide wheels in their designated positions on the forming tension seat, ensuring they are at the same height and the guide groove is oriented correctly so the zipper can pass smoothly. Next, install the self-balancing assembly. Accurately install the moving guide shaft on the side of the forming tension seat, then place the counterweight on the moving guide shaft and connect one side of the counterweight to the forming tension seat via a linear guide. Install the self-balancing guide wheel on the counterweight, ensuring it can rotate freely and is properly positioned for good contact with the zipper. Finally, install the pressing assembly. Fix the drive motor to the forming tension seat, then install the first pressing wheel at the output end of the drive motor. Install the second pressure roller, swing one end of the swing arm to the forming tension seat, connect a spring between the other end of the swing arm and the forming tension seat, and rotatably mount the second pressure roller on the swing arm, ensuring that the edge of the second pressure roller fits well with the pressing groove of the first pressure roller, while ensuring the correct position of the V-groove on the second pressure roller. After installation, debug the entire mechanism. First, manually rotate the first and second guide rollers to check their rotational flexibility, ensuring there is no jamming or excessive friction. At the same time, check whether the guide chute can accurately guide the chain; if there are problems, adjust the position of the guide rollers or clean the debris in the guide chute. For the self-balancing component, check the movement flexibility of the counterweight on the moving guide shaft without the chain passing through. Gently push the counterweight and observe whether it can slide smoothly along the guide rail, and check whether the rotation of the self-balancing guide roller is smooth. Then, the automatic adjustment function of the counterweight can be observed by simulating different tension conditions (such as using objects of different weights to simulate chain tension). This ensures that it can accurately move according to tension changes and adjust the position of the self-balancing guide wheel, thereby achieving effective control of the chain tension. When debugging the pressing assembly, start the drive motor and observe the rotation of the first and second pressing rollers. Check whether their fit is tight and whether the pressing action is smooth. Some test chain samples can be used to pass through the pressing assembly to observe the pressing effect and check for problems such as loose chain pressing or pressing position misalignment. If problems are found, adjust the spring coefficient or check the installation position of the pressing rollers to ensure uniform pressing force and accurate pressing position.
[0035] During the pressing process: When the zipper forming machine starts working, the left and right zippers are guided into the forming tension mechanism from their respective positions. The zippers first pass through the first guide roller, accurately transmitted under the guidance of the guide groove. Next, upon passing the self-balancing component, the zipper contacts the self-balancing guide roller, which automatically adjusts the position of the counterweight according to the initial tension of the zipper, thus providing appropriate tension. Finally, after passing through the second guide roller and changing the direction of the zipper teeth, the zipper continues to be transmitted downwards into the pressing component. Driven by the drive motor, the first pressing roller begins to rotate, causing the second pressing roller to rotate in coordination. The left and right zippers are pressed between the first and second pressing rollers. The pressing groove of the first pressing roller and the V-groove of the second pressing roller position and press the zipper, forming it into a zipper. During the pressing process, the spring-connected second pressing roller automatically adjusts the pressure according to the thickness and width of the zipper, ensuring stable pressing quality. Throughout the zipper forming process, the self-balancing component continuously monitors and adjusts the tension of the zipper. If the tension of the zipper chain changes during the production process (such as changes in the zipper chain supply speed, material, or size), the counterweight will move on the moving guide shaft and adjust the tension of the zipper chain in real time through the self-balancing guide wheel to ensure that the zipper chain always maintains the appropriate tension and to ensure the stability of the zipper forming quality.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art should be able to make equivalent embodiments by making some changes or modifications to the above-disclosed technical content without departing from the scope of the present invention.
