[0002] Textile yarn is a basic material in the textile industry and is widely used in clothing, home furnishings, and industrial fields. It can be made from natural or synthetic fibers. The quality of textile yarn directly determines the quality of textile fabrics made from it. Therefore, during the textile process, it is usually necessary to test the tensile strength of the textile yarn to determine whether the quality of the textile yarn is up to standard.

[0003] Currently, when testing the tensile strength of textile yarns, a specified length of yarn is usually cut from the yarn roll, both ends of the yarn are fixed to the clamps of the tensile testing device, and then the equipment is used to perform the yarn tensile test.

[0004] However, in actual testing, temperature can significantly affect the physical and mechanical properties of materials, which means that the tensile strength of textile yarns is usually different under different ambient temperatures. However, existing testing devices cannot simulate different temperature environments, which means that the devices cannot test the tensile strength of textile yarns under different temperature environments, and cannot accurately determine the quality of the yarns used, thus affecting the quality of subsequent textile products.

[0030] Specifically, during use, by controlling the main unit 4, temperature sensor 9, air pump 51, and heating element together, the inside of the testing cabinet 2 can be heated to a specified temperature. By controlling the main unit 4, temperature sensor 9, air pump 51, and cooling element together, the inside of the testing cabinet 2 can be cooled to a specified temperature. This allows for the simulation of different temperature environments, enabling the device to test the tensile strength of textile yarns under different temperature conditions.

[0031] The heating element includes a heating wire 61 fixedly installed inside the heating shell 6. The heating wire 61 is electrically connected to the control host 4. An air inlet 62 is provided through the heating shell 6. The air inlet 62 is located above the heating wire 61, and the air intake pipe A52 is located below the heating wire 61.

[0032] Specifically, by controlling the host 4 to start the heating wire 61 and the air pump 51, air enters the heating shell 6 through the air inlet 62 and is heated by the heating wire 61. The heated air is then fed into the detection cabinet 2 through the suction pipe A52, the air delivery pipe 53 and the air nozzle 5. When the temperature sensor 9 detects that the temperature inside the detection cabinet 2 has reached the set temperature, the heating wire 61 and the air pump 51 can be turned off, thus heating the inside of the detection cabinet 2 to the specified temperature.

[0033] The cooling component includes a cooling shell 7 fixedly connected to the base 1. An air inlet 71 is provided through the cooling shell 7. A semiconductor cooling chip 72 is fixedly installed on the cooling shell 7. The semiconductor cooling chip 72 is electrically connected to the control host 4. A cooling conductive plate 73 is fixedly installed inside the cooling shell 7. The cooling surface of the semiconductor cooling chip 72 is in contact with the cooling conductive plate 73.

[0034] Specifically, firstly, the solenoid valve B76 is closed and the solenoid valve A75 is opened by the control host 4. Then, the semiconductor cooling chip 72 and the air pump 51 are started. The air pump 51 causes air to enter the cooling shell 7 through the air inlet 71, and the air in the cooling shell 7 is cooled by the semiconductor cooling chip 72 and the cooling plate 73. The cooled air is then fed into the detection cabinet 2 through the suction pipe B74, the air delivery pipe 53 and the air nozzle 5. When the temperature sensor 9 detects that the temperature inside the detection cabinet 2 has reached the set temperature, the semiconductor cooling chip 72 and the air pump 51 can be turned off, which can cool the inside of the detection cabinet 2 to the specified temperature.

A protective net 82 is fixedly connected to the air inlet of the fan housing 8, and the exhaust end of the fan 81 faces the semiconductor cooling chip 72.

[0036] Specifically, by activating the fan 81, outside air enters the base 1 through the protective net 82 and the fan casing 8 and blows onto the heating surface of the thermoelectric cooler 72, which can dissipate heat and cool the heating surface of the thermoelectric cooler 72, thereby ensuring the cooling effect of the thermoelectric cooler 72.

A clamp 32 is fixedly installed on both the force-receiving end of the tension sensor 31 and the inner bottom of the testing cabinet 2. The electric push rod 3 and the tension sensor 31 are both electrically connected to the control host 4.

[0038] Specifically, in use, the two ends of the textile yarn are first fixed by two clamps 32. Then, the electric push rod 3 is activated. The output end of the electric push rod 3 drives the tension sensor 31 and the clamps 32 to pull the textile yarn until the yarn breaks, thereby realizing the detection of the tensile strength of the yarn. The detection value is displayed on the display screen on the control host 4.

[0039] Working principle: During use, the tensile strength testing device for textile yarn starts the heating wire 61 and air pump 51 through the control host 4, allowing air to enter the heating shell 6 through the air inlet 62. The heating wire 61 heats the incoming air, and the heated air is then fed into the testing cabinet 2 through the suction pipe A52, the air delivery pipe 53, and the air nozzle 5. When the temperature sensor 9 detects that the temperature inside the testing cabinet 2 has reached the set temperature, the heating wire 61 and air pump 51 are automatically turned off, thus heating the inside of the testing cabinet 2 to the specified temperature.

[0040] On the other hand, by controlling the host 4 to close the solenoid valve B76 and open the solenoid valve A75, the semiconductor cooling chip 72 and the air pump 51 are started. The air pump 51 causes air to enter the cooling shell 7 through the air inlet 71, and the air in the cooling shell 7 is cooled by the semiconductor cooling chip 72 and the cooling plate 73. The cooled air is then fed into the detection cabinet 2 through the suction pipe B74, the air delivery pipe 53 and the air nozzle 5. When the temperature sensor 9 detects that the temperature inside the detection cabinet 2 has reached the set temperature, the semiconductor cooling chip 72 and the air pump 51 can be automatically turned off, which can cool the inside of the detection cabinet 2 to the specified temperature.

[0041] This device, through the coordinated use of the control host 4, temperature sensor 9, air pump 51, heating wire 61, and semiconductor cooling chip 72, can simulate different temperature environments inside the testing cabinet 2, so as to test the tensile strength of textile yarns under different temperature environments. This allows for a more accurate assessment of the yarn's quality and helps ensure the quality of subsequent textile products.

[0042] When testing textile yarn, the two ends of the textile yarn are fixed by two clamps 32. Then, the electric push rod 3 is activated. The output end of the electric push rod 3 drives the tension sensor 31 and the clamps 32 to pull the textile yarn until the yarn breaks, thereby realizing the tensile strength test of the yarn. The test value can be displayed on the display screen on the control host 4.
