Description

Technical Field

[0001] The invention belongs to the field of color-spun yarn detection, and in particular relates to a color-spun yarn stretching device. Background Art

[0002] The so-called colored yarn is to dye the fiber into colored fiber first, and then fully mix two or more fibers of different colors and spin them into yarn with unique color mixing effect. Colored yarn can achieve the hazy three-dimensional effect and texture that cannot be achieved by dyeing white blanks. Colored yarn is pollution-free to use and can control the color difference to the greatest extent. Therefore, colored yarn with soft and fashionable colors and flexible production of small batches and multiple varieties is increasingly used in mid-to-high-end clothing products. Now, the processed colored yarn needs to go through multiple inspection processes, including a stretching process, which is used to detect the overall tensile strength of the colored yarn.

[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0021] Depend on Figure 1 , Figure 2 and Figure 3As shown, a colored yarn stretching device includes a base 1, a side bracket 2, a tension detector 3 and a control end 4, the side brackets 2 are symmetrically fixedly installed on the surface of the base 1, the tension detector 3 is fixedly installed on the surface of the base 1 between the side brackets 2, the control end 4 is fixedly installed on one side of the surface of the base 1, and a clamping mechanism 5 is symmetrically arranged between the side brackets 2. The clamping mechanism 5 includes an outer shell 51, a clamping assembly 52, a disassembly assembly 53 and a side clamping plate 54. The outer shell 51 is slidably installed between the side brackets 2, the clamping assembly 52 is fixedly installed inside the outer shell 51, the side clamping plate 54 is fixedly installed on one side of the bottom end of the outer shell 51, the disassembly assembly 53 is arranged at the bottom end of the outer shell 51, and the disassembly assembly 53 is fixedly connected to the clamping assembly 52, and a lifting mechanism 6 is arranged between the side brackets 2.

[0022] During use, the device is installed at the target position, and then the colored spun yarn that needs to be tested for tensile strength is placed between the two sets of clamping mechanisms 5. Then, the colored spun yarn is stably clamped and positioned by using the clamping mechanism 5. First, the side clamping plates 54 and the side clamping plates 54 of corresponding sizes are selected according to the specifications and sizes of the colored spun yarn materials to be tested. Then, the two ends of the colored spun yarn that needs to be stretched and tested are placed between the side clamping plates 54 and the disassembly and assembly components 53 respectively. By using and operating the clamping components 52, the position of the disassembly and assembly components 53 is adjusted and changed, so that the disassembly and assembly components 53 can be easily adjusted. The assembly component 53 moves toward the side clamping plate 54 to stably clamp and position the colored yarn between the side clamping plate 54 and the disassembly assembly 53. Then, the clamping mechanism 5 and the colored yarn are installed to corresponding positions through the cooperation of the outer shell 51 and various components. Then, the colored yarn is stretched and tested by using the lifting mechanism 6. This allows the equipment to flexibly adjust the overall specifications of its own disassembly assembly component 53 and the side clamping plate 54 when testing the colored yarn, so as to better stably position the colored yarn and make the equipment's own testing more accurate.

[0023] By the attached Figure 2 As shown, in this embodiment, the clamping mechanism 5 further includes an indicator needle 55 , which is fixedly mounted on one side of the surface of the disassembly assembly 53 , and a scale is provided on the surface of the side bracket 2 .

[0024] During use, by using and cooperating with the indicator needle 55 and the scale on the surface of the side bracket 2, the staff can flexibly and accurately observe the distance between the two sets of outer shells 51 when using the equipment. The staff no longer needs to use a measuring ruler to manually measure, which simplifies the adjustment steps during equipment operation.

[0025] By the attached Figure 3As shown, in this embodiment, the clamping assembly 52 includes a movable groove 521, an upper partition 522, a first screw rod 523, a first guide rod 524, a rotating block 525 and a movable key 526. The outer shell 51 is provided with a movable groove 521, the upper partition 522 is fixedly installed at the opening of the movable groove 521, the first screw rod 523 is rotatably installed between the upper partition 522 and the inside of the movable groove 521, the first guide rod 524 is fixedly installed on the side of the upper partition 522, the first guide rod 524 is fixedly connected to the inside of the movable groove 521, the rotating block 525 is fixedly installed at the end of the first screw rod 523, the movable key 526 is threadedly installed on the outside of the first screw rod 523, the movable key 526 is slidably connected to the first guide rod 524, and the movable key 526 is fixedly connected to the disassembly assembly 53.

[0026] During use, the colored spun yarn to be stretched and tested is placed on the surface of the side clamp 54, and then the rotating block 525 is rotated. Driven by the rotating block 525, the first screw rod 523 rotates between the moving groove 521 and the upper partition 522. Then, with the cooperation of the moving key 526, the disassembly and assembly component 53 at the bottom of the moving key 526 moves together with the moving key 526, so that the distance between the disassembly and assembly component 53 and the side clamp 54 can be flexibly adjusted to achieve stable clamping of the end of the colored spun yarn.

[0027] By the attached Figure 4 As shown, in this embodiment, the disassembly and assembly component 53 includes a linkage plate 531, a positioning block 532, a first spring 533, an upper linkage plate 534 and a clamping plate 539. The linkage plate 531 is fixedly installed at the bottom end of the moving key 526. The positioning block 532 is symmetrically and slidably installed inside the linkage plate 531. The first spring 533 is fixedly installed at the bottom end of the positioning block 532. The upper linkage plate 534 is arranged at the bottom end of the linkage plate 531, and the clamping plate 539 is fixedly installed at the bottom end of the upper linkage plate 534.

[0028] When the locking cam 531 is in the process of being installed, the locking cam 532 is automatically retracted into the locking cam 531 by the internal notch of the locking cam 534. At this time, the first spring 533 enters the force storage state. When the locking cam 531 moves to the target position, the first spring 533 releases its accumulated elastic force and pops the locking cam 532 out of the locking cam 531, and the locking cam 532 enters the upper locking cam 534, completing the combination and connection of the components, and quickly completing the installation and positioning of the clamping plate 539. When in use, the disassembly and assembly assembly 53 and the side clamping plate 54 have the same structure. In the process of replacing components, the second guide rod 63 and the internal components of the side clamping plate 54 can be replaced at the same time.

[0029] By the attached Figure 4As shown, in this embodiment, the disassembly and assembly component 53 also includes a pushing rod 535, a pushing block 536, a second spring 537 and a locking groove 538. The upper connecting plate 534 is symmetrically provided with locking grooves 538, the pushing block 536 is slidably installed in the locking groove 538, the pushing rod 535 is fixedly installed at the end of the pushing block 536, and the second spring 537 is sleeved on the outside of the pushing rod 535.

[0030] When the clamping plate 539 needs to be disassembled during use, the push rod 535 is pressed. Under the push of the push rod 535, the push block 536 moves to the side close to the positioning block 532, squeezing the position of the positioning block 532, allowing the positioning block 532 to re-enter the linkage plate 531. At this time, the clamping plate 539 is pulled to separate the upper connecting plate 534 and the linkage plate 531, and the components are quickly separated, which is convenient for the installation and positioning of subsequent components.

[0031] By the attached Figure 5 As shown, in this embodiment, the colored yarn stretching device also includes a connecting mechanism 7, which includes a connecting end 71, a connecting plate 72, a fixing plate 73 and a positioning assembly 74. The connecting mechanism 7 is provided with two groups, one group of connecting ends 71 ​​is fixedly installed at the bottom end of the lifting mechanism 6, and the other group of connecting ends 71 ​​is fixedly connected to the tension detector 3, the connecting plate 72 is fixedly installed at the bottom end of the connecting end 71, the fixing plate 73 is fixedly installed on the side of the connecting plate 72, and the positioning assembly 74 is fixedly installed on the surface of the outer shell 51.

[0032] During use, the two sets of clamping mechanisms 5 are moved to the target positions respectively, and then the two sets of clamping mechanisms 5 are installed at the bottom end of the lifting mechanism 6 and the top end of the tension detector 3 respectively through the use of the positioning assembly 74. After that, the position of the components is fixed and installed through the use and cooperation of the connecting end 71 and the connecting plate 72, thereby assisting the subsequent rapid stretching of the colored yarn.

[0033] By the attached Figure 5 and Figure 6 As shown, in this embodiment, the positioning assembly 74 includes an installation groove 741, a positioning groove 742, a positioning block 743 and a positioning rod 744. The fixing plate 73 is provided with an installation groove 741, and the fixing plate 73 is symmetrically provided with positioning grooves 742. The positioning groove 742 is communicated with the installation groove 741. The positioning block 743 is fixedly installed on the side of the outer shell 51, and the positioning rod 744 is symmetrically fixedly installed on the bottom end of the positioning block 743. The positioning rod 744 is slidably connected to the positioning groove 742, and the positioning block 743 is slidably connected to the installation groove 741.

[0034] During use, the two sets of clamping mechanisms 5 that have clamped the colored yarn are moved to the target positions respectively, and the positioning block 743 is pressed into the installation groove 741. During the movement of the positioning block 743, it is necessary to ensure that the positioning rod 744 can accurately enter the positioning groove 742 to complete the rapid positioning of the components, so that when the subsequent lifting mechanism 6 moves, the clamping mechanism 5 is driven to move vertically through the connecting mechanism 7.

[0035] By the attached Figure 7 As shown, in this embodiment, the lifting mechanism 6 includes a lifting slot 61, a second screw rod 62, a second guide rod 63, a movable end 64, a driving motor 65 and a lifting rod 66.

[0036] During use, the second screw rod 62 rotates inside the lifting groove 61 through the operation of the driving motor 65, and under the cooperation and limitation of the second guide rod 63, the movable end 64 moves along the thread on the outside of the second screw rod 62, and the movable end 64 is fixedly connected to the lifting rod 66. The lifting rod 66 can pull a group of clamping mechanisms 5 at the bottom end of the lifting mechanism 6 to realize the stretching detection of the colored yarn.

[0037] By the attached Figure 8 As shown, in this embodiment, the lifting mechanism 6 also includes a sliding groove 67 and a sliding block 68. The side bracket 2 is provided with a sliding groove 67. The sliding block 68 is slidably installed inside the sliding groove 67. The sliding block 68 is fixedly connected to the end of the lifting rod 66.

[0038] During use, the cooperation of the sliding groove 67 and the sliding block 68 opened in the other set of side brackets 2 makes the sliding of the lifting rod 66 itself more stable, so that the lifting rod 66 is in a vertical moving state when sliding up and down, ensuring the accuracy and stability during detection.
