Technical Field

[0001] The invention relates to the technical field of textile yarn testing, and in particular to a strong tensile textile yarn testing device and method. Background Art

[0002] Yarn is a kind of textile, which is made of various textile fibers into a product of a certain fineness, used for weaving, rope making, thread making, knitting and embroidery, etc. It is divided into short fiber yarn, continuous filament, etc. Tensile testing machine is also called universal material testing machine. Universal testing machine is a mechanical force testing machine used to perform mechanical property tests such as static load, tension, compression, bending, shearing, tearing, peeling, etc. on various materials.

[0003] However, in many practical application scenarios in our daily lives, yarns are often used in a twisted state. The lack of accurate testing of twisted yarns will lead to a lack of direction in the optimization of the production process, and it is impossible to make targeted improvements to the characteristics of the twisted yarns. In addition, when evaluating the quality of the yarns, it is difficult to accurately grasp the tension differences between multiple yarns, and it is impossible to provide a reliable basis for judging the stability of the production process. This may cause problems such as product breakage in actual applications, reducing the reliability and service life of the product. Summary of the invention

Rotate the extrusion sleeve. When the extrusion sleeve rotates, it gradually approaches the guide cover along the rotating axis. At this time, the inner wall of one end of the extrusion sleeve close to the guide cover gradually conflicts with the outer wall of the connecting rod. As the extrusion sleeve moves, multiple connecting rods are gradually pressed into the interior of multiple accommodating grooves. When the connecting rod gradually approaches the accommodating groove, the pull rod rotatably connected to the connecting rod will be pulled toward the rotating axis. At this time, the pull rod drives the limiter to approach the rotating axis through the connecting ring and the U-shaped handle, and then pulls the limiter away from the slot, which is convenient for the operator to place the textile yarn inside the slot, and further wind the wire into the wire management slot opened on the outer wall of the column, and rotate the extrusion sleeve in the opposite direction to release the multiple connecting rods. Under the action of the return spring, the limiter is driven to insert into the interior of the slot, thereby fixing the textile yarn; S2. further starting the test motor, which drives the threaded rod to rotate, so that the two connecting blocks gradually move away from each other, and then drive the two moving frames to gradually move away from each other. When the two moving frames gradually separate, the textile yarn fixed on the column will be pulled, and during the pulling process, the tension of the textile yarn will be tested; S3. When multiple yarns need to be tested after twisting, the drive motor is started, and the gear provided at the output end of the drive motor is meshed with the matching teeth provided on the outer wall of the rotating ring, so that the drive motor drives one of the rotating rings to rotate, and the position of the other rotating ring is relatively fixed, so that the textile yarns located inside the rotating ring are rotated and twisted; S4. After twisting, start the test motor to perform a tension test on the twisted yarn.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are: Through the coordinated use of rotating rings, columns, slots, stands, limiters, return springs, test motors, threaded rods, and connecting blocks, it is convenient to perform equal force tests on multiple yarns, thereby facilitating the observation of the tension differences between the yarns, and further facilitating the recording of the stability of the production process, which is conducive to continuously optimizing the production process, improving yarn quality, and ensuring that each yarn meets higher quality standards.

[0022] Through the coordinated use of the limit ring, rotating ring, driving motor and column, it is convenient to twist multiple cables, which can more realistically simulate the state of the yarn in actual use, making the test results more valuable for practical reference.

[0023] Through the coordinated use of the rotating shaft, connecting rod, guide cover, pull rod, connecting ring, threaded groove and extrusion sleeve, multiple cables can be installed simultaneously, thereby improving the installation of textile yarns by operators and improving testing efficiency.

When the two movable frames 201 gradually separate, the textile yarn fixed on the column 205 will be pulled, and during the pulling process, the tension of multiple textile yarns will be tested.

[0028] like Figure 4 As shown, the tops of the multiple columns 205 are fixedly connected with the stands 207, the outer side walls of the multiple stands 207 are respectively slidably connected with the outer side walls of the limit members 208, the tops of the multiple limit members 208 are fixedly connected with the return springs 209, and the ends of the return springs 209 away from the multiple limit members 208 are respectively fixedly connected with the bottoms of the stands 207.

The two mounting frames 301 are respectively located on both sides of the top of the support platform 1, and the inner side walls of the two mounting frames 301 are rotatably connected with a rotating shaft 302, and the ends of the two rotating shafts 302 that are close to each other are rotatably connected, and the outer side walls of the two rotating shafts 302 are fixedly connected with guide covers 305, and the outer side walls of the two guide covers 305 are provided with through holes, and the inner side walls of the two guide covers 305 are slidably connected with a plurality of pull rods 306, and the outer side walls of the two rotating shafts 302 are respectively provided with a plurality of accommodating grooves 303, and the plurality of accommodating grooves 303 are respectively arranged along the outer sides of the two rotating shafts 302. The walls are distributed in a circle, and the inner walls of the two rotating shafts 302 are rotatably connected with multiple connecting rods 304 respectively. The ends of the multiple connecting rods 304 away from the pull rods 306 are respectively located inside the multiple accommodating grooves 303, and the ends of the multiple connecting rods 304 close to the multiple pull rods 306 are rotatably connected to the multiple pull rods 306. When in use, the operator can press the connecting rod 304 in the direction of the accommodating groove 303 to retract the connecting rod 304 into the interior of the accommodating groove 303. Further, the pull rod 306 is driven by the connecting rod 304 to approach the direction of the rotating shaft 302. At this time, the guide cover 305 drives the limit piece 208 to move out of the interior of the slot 206, which is convenient for the operator to place multiple textile yarns.

When the two moving frames 201 gradually separate, the textile yarn fixed on the column 205 is pulled, and the tension of the textile yarn is tested during the pulling process; S3. When multiple yarns need to be tested after twisting, the drive motor 204 is started, and the gear provided at the output end of the drive motor 204 is meshed with the matching teeth provided on the outer wall of the rotating ring 203, so that the drive motor 204 drives one of the rotating rings 203 to rotate, and the position of the other rotating ring 203 is relatively fixed, so that the textile yarns located inside the rotating ring 203 are rotated and twisted; S4.
