Therefore, the first power rod 511 and the second power rod 512 will be driven to move toward each other, thereby driving the first friction seat 153 and the second friction seat 154 to move toward each other, so that the first friction seat 153 and the second friction seat 154 are in contact with the surface of the nylon yarn, and then the reciprocating component 6 drives the sliding seat 151, the placement seat 152, the first friction seat 153 and the second friction seat 154 to reciprocate along the length direction of the slide rail 15. The length direction of the slide rail 15 is consistent with the length direction of the nylon yarn, and the slide rail 15 is located directly below the nylon yarn. Therefore, the first friction seat 153 and the second friction seat 154 will continuously rub the nylon yarn, thereby completing the wear resistance test of the nylon yarn.

A second driving motor 64 is fixedly mounted on the frame 1, and a driving gear 65 is coaxially mounted on the output shaft of the second driving motor 64. A driven gear 66 is coaxially mounted on the driving shaft 62, and the driving gear 65 is meshed with the driven gear 66. When in use, the second driving motor 64 is rotated. Rotation, the second drive motor 64 will drive the driving gear 65 to rotate synchronously during the rotation of the second drive motor 64, and the driving gear 65 will drive the driven gear 66 to rotate during the rotation of the driven gear 66. The driving shaft 62 will be driven to rotate during the rotation of the driven gear 66, thereby driving the driving disk 61 to rotate synchronously. During the rotation of the driving disk 61, the sliding seat 151 will be driven to reciprocate along the length direction of the slide rail 15 through the connecting rod 63, thereby facilitating the first friction seat 153 and the second friction seat 154 to perform wear resistance detection on the nylon yarn.

[0048] like Figures 5 to 8 As shown, the adjustment assembly 7 includes an adjustment rail 71, which is arranged along the radial direction of the drive disk 61, and an adjustment block 72 is slidably installed on the adjustment rail 71. The connecting rod 63 and the adjustment block 72 are hinged to the adjustment rail 71, and an adjustment screw rod 73 is installed for rotation inside the adjustment rail 71. The adjustment screw rod 73 is threadedly connected to the adjustment block 72, and a first bevel gear 74 is coaxially installed on the end of the adjustment screw rod 73 close to the drive shaft 62.

During the rotation of the adjustment motor 77, the adjusting shaft 75 will be driven to rotate synchronously. During the rotation of the adjusting shaft 75, the second bevel gear 76 will be driven to rotate synchronously. During the rotation of the second bevel gear 76, the first bevel gear 74 will be driven to rotate. During the rotation of the first bevel gear 74, the adjusting screw rod 73 will be driven to rotate synchronously. During the rotation of the adjusting screw rod 73, the adjusting block 72 will be driven to move along the length direction of the adjusting rail 71. When the adjusting block 72 moves toward the center position away from the driving disk 61, the first friction seat 153 and the second friction seat 154 will increase the friction distance with the nylon yarn. When the adjusting block 72 moves toward the center position close to the driving disk 61, the first friction seat 153 and the second friction seat 154 will reduce the friction distance with the nylon yarn.

[0049] like Figures 5 to 8As shown, a first wire lifting frame 17 and a second wire lifting frame 18 are installed on the top of the frame 1. The second wire lifting frame 18 has the same structure and size as the first wire lifting frame 17. The first wire lifting frame 17 and the second wire lifting frame 18 are respectively located on both sides of the placement seat 152, and one end of the first wire lifting frame 17 is slidably installed on the first mounting seat 13, and the other end is slidably installed on the second mounting seat 14. The first wire lifting frame 17 and the second wire lifting frame 18 are both rotatably installed with a wire lifting roller 19, and the nylon yarn is tangent to the top of the wire lifting roller 19. An adjustment slide rail 8 is installed on one side of the first mounting seat 13. A first sliding block 81 is installed, the first sliding block 81 is slidably installed in the adjustment slide rail 8, a second sliding block 82 is installed on the second wire lifting frame 18, the second sliding block 82 is slidably installed in the adjustment slide rail 8, a bidirectional screw rod 83 is rotatably installed in the adjustment slide rail 8, the first sliding block 81 is threadedly connected to one end of the bidirectional screw rod 83, the second sliding block 82 is threadedly connected to the other end of the bidirectional screw rod 83, a third bevel gear 84 is coaxially installed on the bidirectional screw rod 83, a connecting shaft 85 is rotatably installed on the frame 1, one end of the connecting shaft 85 is coaxially installed with a fourth bevel gear 86, and the other end is coaxially installed with a fifth bevel gear The fourth bevel gear 86 is meshed with the third bevel gear 84, and the other end of the adjusting shaft 75 is provided with a sixth bevel gear 88, and the fifth bevel gear 87 is meshed with the sixth bevel gear 88; when in use, the nylon yarn is tangent to the top of the wire lifting roller 19, and the wire lifting roller 19 on the first wire lifting frame 17 and the second wire lifting frame 18 will support the nylon yarn so that the nylon yarn remains in a horizontal position, so that the first friction seat 153 and the second friction seat 154 can subsequently perform wear resistance testing on the nylon yarn; when the adjusting motor drives the adjusting shaft 75 to rotate, the sixth bevel gear 88 on the adjusting shaft 75 is installed. The bevel gear 88 will rotate synchronously, and the sixth bevel gear 88 will drive the fifth bevel gear 87 to rotate during the rotation process. The fifth bevel gear 87 will drive the connecting shaft 85 and the fourth bevel gear 86 to rotate synchronously during the rotation process of the fourth bevel gear 86. The third bevel gear 84 will drive the bidirectional screw rod 83 to rotate synchronously during the rotation process. The threads at both ends of the bidirectional screw rod 83 are reversed. Therefore, during the rotation process of the bidirectional screw rod 83, the first wire lifting frame 17 and the second wire lifting frame 18 will be driven to move towards each other or towards each other.When the adjustment motor 77 drives the adjustment block 72 toward a position away from the center of the drive disk 61, the bidirectional screw rod 83 drives the first and second thread lifting frames 17 and 18 to move away from each other, thereby preventing the first and second friction seats 153 and 154 from colliding with the first and second thread lifting frames 17 and 18 during their reciprocating movement. When the adjustment motor 77 drives the adjustment block 72 toward a position closer to the center of the drive disk 61, the bidirectional screw rod 83 drives the first and second thread lifting frames 17 and 18 to move toward each other, thereby facilitating support of the nylon yarn.

[0050] like Figures 4 and 5 As shown, a V-shaped shearing knife 26 is installed on one side of the first push rod 212 and the second push rod 222; when in use, when the driving assembly 2 drives the active rod 21 to move toward a position close to the first clamping seat 1311 and the second clamping seat 1321, the first push rod 212 and the second push rod 222 will move synchronously, thereby driving the shearing knife 26 to move synchronously. When the shearing knife 26 contacts the nylon yarn, the shearing knife 26 will cut the nylon yarn without the need for manual operation by the staff or the use of additional cutting devices.

[0051] The implementation principle of this embodiment is as follows: the driving component 2 drives the first clamping arm 131 and the second clamping arm 132 to clamp and fix the nylon yarn at the same time; when performing a tensile resistance test, the stretching component 3 drives the second clamping arm 132 to move in a direction away from the first clamping arm 131, and then the front and back lengths of the nylon yarn are measured to obtain the tensile resistance of the nylon yarn; when it is necessary to perform a wear resistance test on the nylon yarn, the clamping component 5 drives the first friction seat 153 and the second friction seat 154 to move in a direction approaching each other, so that the first friction seat 153 and the second friction seat 154 are in contact with the surface of the nylon yarn, and then the reciprocating component 6 drives the sliding seat 151 to reciprocate along the length direction of the slide rail 15. The first friction seat 153 and the second friction seat 154 wear the nylon yarn during the reciprocating movement. After a period of time, the wear of the nylon yarn is detected to obtain the wear resistance of the nylon yarn.
