Description

Technical Field

[0001] This utility model relates to the field of clothing, specifically to a high-efficiency zipper tape warping tension control device. Background Technology

[0002] In the modern zipper manufacturing industry, the tape warping process is one of the key steps determining zipper quality and production efficiency. As a crucial component of the zipper, the quality of the tape directly impacts the zipper's durability, aesthetics, and user experience. Tension control during the warping process is a core element in ensuring tape quality. With the continuous expansion of zipper applications, market demands for zipper product quality are increasing. In the apparel industry, high-end fashion has stringent standards for the color uniformity and surface smoothness of zipper tape; in industrial applications such as outdoor equipment and bag manufacturing, zippers require high strength and high abrasion resistance, posing a greater challenge to the tension stability of the tape warping process. However, current zipper tape warping equipment on the market has significant deficiencies in tension control.

[0003] Traditional zipper tape warping tension control devices mostly employ simple mechanical friction structures, such as relying on spring pressure or manual adjustment of friction plates to control tension. This method is not only cumbersome to operate, but also difficult to precisely adapt to zipper tapes of different materials and wire diameters. For example, for tapes made of chemical fibers such as nylon and polyester, their elastic modulus differs significantly from that of natural fibers such as cotton and linen. Traditional devices cannot accurately adjust the tension according to the material characteristics, easily leading to overstretching or slack of the tape during warping. Overstretching reduces tape strength and causes dimensional deformation, resulting in problems such as tooth mismatch during subsequent zipper assembly; while insufficient tension causes wrinkles and knots on the tape surface, affecting the continuity of warping and production efficiency. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a high-efficiency tension control device for zipper tape warping. This patent utilizes a tension control mechanism installed between the feed roller and take-up roller of the machine. A drive mechanism rotates a gear, which meshes with a rack to drive a slider to slide within a groove, thereby moving the tension control roller up and down and changing the tape wrapping angle and path length to precisely adjust the tension. Simultaneously, a tension detection guide roller located at the front center of the machine monitors the tape tension in real time and feeds the data back to the control system. The combined effect of the tension control roller and the rotating guide roller forms a closed-loop control, effectively solving the problems of inaccurate tension control, delayed response, and high reliance on manual labor in traditional zipper tape warping, achieving high-precision and automated tension control.

Detailed Implementation

[0020] The following will refer to the appendix in the example of this utility model. Figures 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1-3 As shown, this utility model provides a high-efficiency zipper tape warping tension control device, including a machine base 1. A feed roller 2 is arranged on the left front side of the machine base 1, and a take-up roller 3 is arranged on the right front side of the machine base 1. The device is characterized by a tension control mechanism 4 arranged between the feed roller 2 and the take-up roller 3. A tension detection guide roller 5 is arranged in the middle of the front end of the machine base 1. Auxiliary guide rollers 6 are fixed on the left and right sides of the front end of the machine base 1. A control panel 7 is arranged at the front of the machine base 1.

[0022] The machine base 1 is the basic support structure of the entire device, providing an installation carrier for all components such as the feeding roller 2, the receiving roller 3, and the tension control mechanism 4, ensuring that the relative positions of each component are fixed and guaranteeing the stability and reliability of the device during operation.

[0023] The feed roller 2 is used to mount the zipper tape raw material roll. Its rotation gradually releases the tape, providing a source of tape for the warping process. The take-up roller 3 is responsible for winding and collecting the tape after tension control and warping, forming a neat roll for easy subsequent processing and use. The tension control mechanism 4 is the core component of the device. Through a drive mechanism, it rotates a gear, which meshes with a rack to drive a slider to slide within a groove, thus moving the tension control roller up and down. This changes the tape wrap angle or path length, precisely adjusting the tension during the warping process. The tension detection guide roller 5 monitors the tape tension in real time during warping, converting the tension data into processable signals such as electrical signals, and feeding them back to the control system. This provides a basis for the adjustment of the tension control mechanism 4, achieving closed-loop tension control. Auxiliary guide rollers 6 are installed on the left and right sides of the front of the machine base 1 to assist in guiding the direction of the fabric belt and prevent problems such as belt deviation and entanglement during transmission. This ensures that the fabric belt can pass smoothly and accurately through components such as the unloading roller 2, tension control mechanism 4, and tension detection guide roller 5, and reach the take-up roller 3. Operators can set various parameters in the warping process through the control panel 7, such as the target tension value and the winding and unwinding speed. At the same time, the control panel 7 receives tension data fed back by the tension detection guide roller 5, analyzes and processes it, and sends control commands to the tension control mechanism 4 to realize the automation and intelligence of warping tension control.

[0024] The tension control mechanism 4 includes a mounting plate 41. A drive mechanism 42 is located on the left side of the mounting plate 41, and an outer plate 43 is fixed to the right side of the mounting plate 41. A drive shaft 44 is fixed to the end of the output shaft of the drive mechanism 42, and a gear 45 is axially fixed to the drive shaft 44. A rack 46 is embedded on the outer side of the mounting plate 41 and the outer plate 43. A slide groove 47 is provided on the inner side of the mounting plate 41 and the outer plate 43. A slider 48 is slidably connected inside the slide groove 47. A tension regulating roller 49 is provided between the sliders 48, and a rotating guide roller 50 is provided at the lower end of the tension regulating roller 49. The slider 48 is fixedly connected to the rack 46. The gear 45 is located on the outer side of the mounting plate 41 and the outer plate 43. A guide groove 411 matching the outer edge of the rack 46 is provided on the outer side of the mounting plate 41 and the outer plate 43. The upper and lower ends of the guide groove 411 are limit strokes.

[0025] The mounting plate 41 forms the basic frame of the mechanism, fixing the drive mechanism 42 to the left and connecting to the outer side plate 43 on the right, providing structural support for the entire tension control mechanism and ensuring the stability of each component. The outer side plate 43 is parallel to the mounting plate 41, providing track constraints for the sliding of the slider 48. The drive mechanism 42 is a servo motor or stepper motor, providing the power source and driving the drive shaft 44 to rotate via the output shaft, realizing automated control of tension regulation. The drive shaft 44 connects the drive mechanism 42 and the gear 45, transmitting the rotational motion of the motor to the gear 45, ensuring the stability of power transmission. The gear 45 and the rack 46 form the core transmission pair. When the gear 45 rotates, it meshes with the rack 46, converting the circular motion into the linear motion of the rack 46, ensuring the accuracy of the tension regulating roller 49 position adjustment.

[0026] The slider 48 is embedded in the groove 47 and fixedly connected to the rack 46. When the rack 46 moves linearly, the slider 48 slides synchronously along the groove 47, providing a vertical linear motion track for the tension regulating roller 49 and ensuring smooth movement. The guide groove 411 is located outside the mounting plate 41 and the outer side plate 43, matching the outer edge of the rack 46, further constraining the movement trajectory of the rack 46 and preventing lateral deviation. The upper and lower ends of the guide groove 411 are equipped with limit strokes to limit the maximum movement range of the rack 46 and prevent the mechanism from malfunctioning due to over-limit operation.

[0027] The tension regulating roller 49 acts directly on the core component of the zipper tape, moving up and down via the slider 48 to change the wrapping angle or path length of the tape. The rotating guide roller 50 is located at the lower end of the tension regulating roller 49 and can rotate freely. It guides the tape direction, reduces the frictional resistance between the tape and the roller surface, prevents damage to the tape due to excessive friction, and assists the tension regulating roller 49 in forming a stable tape path.

[0028] Working principle:

[0029] The zipper tape material is released by the feed roller 2 on the left side of the front of the machine 1, passes around the tension detection guide roller 5 in the middle of the front of the machine 1, and enters the tension control mechanism 4 between the feed roller 2 and the take-up roller 3. Finally, it is wound up by the take-up roller 3 on the right side of the front of the machine 1.

[0030] In the tension control stage, the drive mechanism 42 in the tension control mechanism 4 is energized, driving the drive shaft 44 and the gear 45 fixed thereon to rotate. The gear 45 is located on the outside of the mounting plate 41 and the outer plate 43, meshing with the rack 46 on the outside of the mounting plate 41 and the outer plate 43, converting the rotational motion into linear motion, pushing the slider 48 fixedly connected to the rack 46, causing it to slide up and down in the groove 47 on the inside of the mounting plate 41 and the outer plate 43. The slider 48 drives the tension regulating roller 49 to move synchronously. When the tension regulating roller 49 moves upward, it increases the wrap angle or path length of the fabric belt. According to Euler's formula, the frictional resistance of the fabric belt increases during operation, thereby increasing the tension. When the tension regulating roller 49 moves downward, it decreases the wrap angle and path length of the fabric belt, reducing the frictional resistance and tension. The rotating guide roller 50 located at the lower end of the tension regulating roller 49 can rotate freely, reducing the friction between the fabric belt and the roller surface, and at the same time helping to stabilize the direction of the fabric belt.

[0031] The auxiliary guide rollers 6 on the left and right sides of the front of the machine 1 further regulate the direction of the fabric belt, ensuring stable transmission of the fabric belt. The tension detection guide roller 5 monitors the tension of the fabric belt in real time and feeds the data back to the control panel 7 at the front of the machine 1. The control panel 7 automatically adjusts the operating status of the drive mechanism 42 according to the difference between the preset tension value and the actual monitored value, and precisely controls the position of the tension regulating roller 49 to form a closed-loop control, ensuring that the fabric belt maintains a stable tension that meets the process requirements throughout the warping process.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
