Description

Technical Field

[0001] The invention belongs to the technical field of yarn detection, and in particular relates to a textile yarn performance testing device. Background Art

[0002] Yarn is a textile product made from various textile fibers processed into a certain fineness for weaving, rope making, thread making, knitting and embroidery.

[0003] The performance of textile yarns has an important impact on the quality and durability of fabrics. Before textile yarns leave the factory, the performance of textile yarns is usually tested to check whether this batch of textile yarns meets the factory requirements. However, when testing the maximum tensile force that textile yarns can withstand, the existing technology usually cuts a section of yarn from the yarn tube and uses a testing device to pull the yarn. After the yarn breaks, the tensile force that the yarn withstands at the time of breakage is the maximum tensile force that the yarn can withstand. However, in order to change the surface texture and glossiness of the yarn and improve the appearance and feel of the fabric during subsequent use, the yarn is usually twisted, and the maximum tensile force that the yarn can withstand is 100%. A certain amount of twisting can enhance the structural stability of the yarn and increase its tensile strength. However, when the twisting is too much, the internal structure of the yarn will be over-compressed, the friction between the fibers will increase, and the tensile strength of the yarn will decrease. The existing technology can only perform tensile tests on a section of untwisted yarn, and cannot accurately test the maximum tensile force that the yarn can withstand after twisting, which will lead to a gap between the test results and the actual performance. Moreover, the test results are only based on the untwisted yarn, which can easily lead to quality control problems in the production process, greatly reducing the reliability and detection effect of the test device when detecting the maximum tensile force of the textile yarn.

[0034] Specifically, the maximum tensile force that a single strand of yarn can withstand can be detected, and the yarn can be automatically twisted after being taken off the take-up reel to simulate the specific use state of the yarn when the subsequent textile yarn is in use, and then the maximum tensile force of the twisted yarn can be tested to prevent the gap between the test result when only testing a single strand of yarn and the actual use performance, and to avoid quality control problems in the production process when the manufacturer debugs the production machine according to the test results. At the same time, when twisting the yarn, the twisting degree of the yarn can be changed according to the specific situation of the subsequent use of the yarn, so as to accurately test the maximum tensile force that yarns with different twisting degrees can withstand, thereby improving the reliability and detection effect of the device when testing the maximum tensile force of textile yarns.

[0035] In the embodiment, the friction detection assembly 13 includes an eighth electric telescopic rod 131 fixedly connected to the top side wall of the base plate 1, the telescopic end of the eighth electric telescopic rod 131 is fixedly connected to the third fixed block 132, the side wall of the third fixed block 132 is fixedly connected to the ninth electric telescopic rod 133, and the telescopic end of the ninth electric telescopic rod 133 is fixedly connected to the friction plate 134.

[0036] Specifically, after the single yarn or the twisted yarn is straightened by using the yarn fixing component 8, the tension detection component 10 and the yarn twisting auxiliary component 12, the ninth electric telescopic rod 133 is controlled to start so that the friction plate 134 is located directly below the yarn, and then the tenth electric telescopic rod is controlled to start so that the friction plate 134 contacts the yarn and then continues to move upward for two centimeters. Then, a small pressure is applied to the yarn by using the friction plate 134, and then the ninth electric telescopic rod 133 is controlled to reciprocate and extend so that the friction plate 134 continuously rubs the yarn. When the yarn breaks, the number of extensions of the ninth electric telescopic rod 133 is recorded, so as to judge the performance of the single yarn or the twisted yarn when subjected to friction, thereby improving the effect and efficiency of the yarn performance test of the device.

[0037] The operating principle of the present invention is now described as follows:

[0038] In the present invention, when it is necessary to test the maximum tensile force of the produced textile yarn, the staff first inserts the take-up drum into the outside of the installation rod 4, and then controls the first electric telescopic rod 5 to start, driving the fixed plate 6 to move toward the inner wall of the take-up drum, and uses the fixed plate 6 to fix the take-up drum. After that, the staff passes one end of the yarn through the installation ring 82 and the detection ring 104, and then controls the fourth electric telescopic rod 105 and the fifth electric telescopic rod 1010 to start, respectively driving the second clamping plate 107 and the third clamping plate 1011 to move in the direction of the yarn to fix one end of the yarn, and then controls the first electric slide rail 101 to start, driving the first slide plate 102 and the detection ring 104 to move, and at the same time controls the first motor 7 to start, so that the fixed rod and the take-up drum are connected. The drum rotates so that the speed of the take-up drum rotates matches the speed at which the first slide 102 drives the detection ring 104 to move, ensuring that the yarn always remains in a straightened state. After the detection ring 104 drives one end of the yarn to move a certain distance, the second electric telescopic rod 89 is controlled to start, and the second clamping plate 107 is used to fix the yarn. At the same time, the third electric telescopic rod 812 is controlled to start, driving the cutting plate 813 to move in the direction of the yarn to cut the yarn. Then, the first electric slide rail 101 is controlled to continue to start, and the second clamping plate 107 and the third clamping plate 1011 are used to pull one end of the yarn in the moving direction of the first slide 102. In this process, the yarn is continuously subjected to tension. At the same time, the second clamping plate 107 and the third clamping plate 1011 continuously pull the yarn when fixing it. The first tension sensor 1012 will detect the value of the pulling force of the second clamping plate 107 and the third clamping plate 1011 on the yarn at this time. As the first slide plate 102 moves, when the yarn breaks, the tension value detected by the first tension sensor 1012 is used to judge the maximum tension that the yarn can withstand before it is twisted. Then the staff will continue to operate one end of the yarn according to the above steps, and then fix one end of the yarn. After the first slide plate 102 passes the twisting rod 1211, the seventh electric telescopic rod 125 is controlled to drive the U-shaped plate 126 to move in the direction of the yarn, so that the U-shaped plate 126 is located on the other side of the yarn, and then the fourth motor 128 is controlled to start, driving the side rod 127 and the twisting rod 1211 to rotate. The sixth electric telescopic rod 123 is controlled to start, and the twisting rod 1211 is driven to move upward so that the twisting rod 1211 and the yarn are located in the same plane. Then, the seventh electric telescopic rod 125 is controlled to retract. After the twisting rod 1211 contacts the yarn, the seventh electric telescopic rod 125 drives the twisting rod 1211 to continue to move a distance. Then, the first electric slide rail 101 is controlled to drive the first slide plate 102 to move toward the mounting ring 82. At the same time, the third motor 106 is controlled to start, and the fourth electric telescopic rod 105 is driven to rotate. Under the limit cooperation between the card plate and the card slot 1014, the fifth electric telescopic rod 1010, the third clamping plate 1011 and the second clamping plate 107 are driven to rotate. After the fourth electric telescopic rod 105 rotates 180 degrees,At this time, one end of the yarn fixed by the second clamping plate 107 and the third clamping plate 1011 is facing the mounting ring 82. After the first slide plate 102 moves to the initial position, one end of the yarn is located inside the mounting ring 82. Then, the second electric telescopic rod 89 is controlled to start, and the second clamping plate 107 is used to fix the two strands of yarn inside the mounting ring 82. During this process, the first motor 7 stops running, and then the fourth electric telescopic rod 105 and the fifth electric telescopic rod 1010 are controlled to drive the second clamping plate 107 and the third clamping plate 1011 to return to their original positions, and then the seventh electric telescopic rod 125 is controlled to drive the twisting rod 1211 to move so that the yarn is located directly above the first groove 9. Then, the second electric slide rail 121 is controlled to start, driving the second slide plate 122 After the twisting rod 1211 moves a certain distance, the second electric slide rail 121 is closed. During this process, the operating speed of the first motor 7 also matches the speed at which the second electric slide rail 121 drives the second slide plate 122 to move. Then, the third electric telescopic rod 812 is controlled to start, so that the cutting plate 813 cuts the yarn. Then, the second motor 88 is controlled to start, driving the round rod 86 and the outer gear 87 to rotate, so that the circular gear 84 drives the side plate 85 to rotate. During this process, the two strands of yarn will continue to rotate to achieve the twisting of the yarn. At this time, the twisting degree of the yarn can be changed by controlling the number of rotations of the circular gear 84. At the same time, as the yarn is twisted, the second electric slide rail 121 is controlled to drive the second slide plate 122 to continuously move toward the direction of the detection ring 104. When the yarn is continuously contracted during the twisting process, it is ensured that the twisting rod 1211 does not apply a large pulling force to the yarn while the yarn is in a straightened state. After the twisting of the yarn is completed, the second electric slide rail 121 is controlled to start, so that the second slide plate 122 moves in the opposite direction of the detection ring 104, and the twisting rod 1211 is used to apply tension to the twisted yarn. At this time, the second tension sensor 1213 will continuously detect the tension of the twisting rod 1211 on the yarn. When the twisted yarn breaks, the tension detected by the second tension sensor 1213 is the maximum tension that the twisted yarn can withstand, thereby completing the maximum tension test of the twisted yarn, and then the component fixing the yarn is controlled to return to its original position, and the staff rotates the limit Plate 1212, so that the limit plate 1212 is separated from the twisting rod 1211, and the twisted yarn can be removed, which is convenient for subsequent testing of the next batch of yarns, and can detect the maximum tensile force that a single strand of yarn can withstand. At the same time, after the yarn is taken off the take-up drum, the yarn can be automatically twisted to simulate the specific use state of the yarn when the subsequent textile yarn is used, and then the maximum tensile force of the twisted yarn can be tested to prevent the gap between the test result when only testing a single strand of yarn and the actual use performance, and avoid quality control problems in the production process when the manufacturer debugs the production machine according to the test results. At the same time, when twisting the yarn, the twisting degree of the yarn can be changed according to the specific situation of the subsequent use of the yarn.In this way, the maximum tensile force that yarns with different twist degrees can withstand can be accurately tested, and the reliability and detection effect of the device in testing the maximum tensile force of textile yarns can be improved.
