[0002] After the processing of nylon DTY low-elastic yarn is completed, various parameters and performances of nylon need to be tested to ensure that the product meets the standards. The electronic single yarn strength tester is a device specially used to test the strength of nylon and various fibers.

[0003] According to the patent document CN202222293618.4, an electronic single yarn strength machine is proposed, which relates to the field of textile testing equipment. The electronic single yarn strength machine includes a strength machine body, an upper clamp seat and a lower clamp seat, a column is arranged on the strength machine body and near the left end, a lifting seat is arranged on the rear side of the upper clamp seat, and a lifting assembly is arranged below the lifting seat and inside the column, and the lifting assembly includes a threaded sleeve and a second screw rod, and a clamping mechanism is arranged on the front side of the upper clamp seat and the lower clamp seat. When the electronic single yarn strength machine is tested, the second bevel gear is driven to rotate by rotating the handle, so that the second bevel gear is meshed with the first bevel gear for transmission, and the threaded sleeve and the second screw rod move relative to each other, which can drive the lifting seat to move up and down, so that the height of the upper clamp seat can be adjusted, and the pulling range between the upper clamp seat and the lower clamp seat can be expanded, thereby increasing the measurement range of the yarn length and enhancing the test effect of the yarn elongation.

[0039] Through the structural design of the clamping mechanism, the cylinder 32 is started to push the first push rod 34 and the second push rod 35 to move, and the push block 38 fixed on the first push rod 34 and the second push rod 35 can push the mobile clamp 26 to move, so that the yarn is automatically fixed by the mobile clamp 26, which is convenient for fixing the yarn, improves the detection efficiency, and the detection personnel do not need to bend down to operate. When working, first pull the yarn to the front of the electronic strong single yarn machine 1, and make the yarn roughly between the fixed clamp 23 and the mobile clamp 26, and then start the cylinder 32, and the cylinder 32 will push The fixed block 33 moves in the horizontal direction, and the fixed block 33 is rotatably connected with the first push rod 34 and the second push rod 35, so the fixed block 33 will push the first push rod 34 and the second push rod 35 to move, the first push rod 34 is rotatably connected with the sliding block 50, and the second push rod 35 is rotatably connected with the slider 39, and the slider 39 and the sliding block 50 both slide on the guide rod 40 and can only move in the vertical direction, and the pushing block 38 fixed on the slider 39 and the sliding block 50 moves in the vertical direction and moves away from each other, and the pushing block 38 will abut against the inner wall of the abutment groove 31 when moving and push The movable clamp 26 moves, and the movable clamp 26 is connected to the fixed clamp 23 through the spring 28. The two sets of springs 28 will be compressed, and the movable clamp 26 will be close to the fixed clamp 23 to complete the clamping and fixing of the yarn between the fixed clamp 23 and the movable clamp 26. At this time, the upper and lower ends of the yarn will be clamped and fixed, so as to facilitate subsequent detection and avoid wasting more time in the process of fixing the yarn, resulting in low detection efficiency. When the yarn is fixed, the driving mechanism inside the electronic strong single yarn machine 1 will drive the base 25 at the bottom to move, while the top base 25 remains fixed. Thereby, the tensile strength of the yarn is tested. Similarly, when the test is completed, the cylinder 32 drives the fixed block 33 to move in the opposite direction, and the first push rod 34 and the second push rod 35 pull the push block 38 to move. The two groups of push blocks 38 approach each other, and the mobile clamp 26 will be reset under the action of the spring 28 and move away from the fixed clamp 23. The mobile clamp 26 no longer contacts the yarn, so that the yarn can be removed. The plug-in rod 29 is inserted in the slot 30 and passes through the slot 30. The plug-in rod 29 can provide support and guidance for the movement of the mobile clamp 26 to ensure the smooth movement of the mobile clamp 26.

[0040] Through the structural design of the straightening component, the yarn may not be straightened after being pulled down. In order to facilitate subsequent detection, the second push rod 35 will drive the slider 39 to move downward while moving, and the slider 39 will pull the winding post 45 to move downward, so that the yarn wound on the winding post 45 will be straightened before the movable clamp 26 clamps the yarn. During operation, when the second push rod 35 moves downward, it will push the slider 39 to slide downward on the guide rod 40, and the slider 39 is connected to the winding post 45 through the fixing ring 42, which will drive the winding post 45 to move downward, and the rear end of the winding post 45 will slide in the U-shaped groove 44, and before the yarn is clamped and fixed, the bottom end of the yarn is wound around the winding post 45, and when the winding post 45 moves downward, the yarn is automatically straightened, so that the yarn can be in a straightened state during detection, which is convenient for the electronic high-strength single yarn machine 1 to detect.

[0041] Further, the fixed assembly includes a connecting rod 49, the connecting rod 49 is rotatably connected to the sliding block 50, the left side of the connecting rod 49 is rotatably connected to the moving block 48, the left side of the moving block 48 is fixedly connected with an insertion rod 47, the insertion rod 47 is inserted on the clamping block 46, and the clamping block 46 is fixedly connected to the electronic strong single yarn machine 1;

[0042] Through the structural design of the fixing component, when the first pushing rod 34 pushes the sliding block 50 to move upward, the moving block 48 will move toward the direction close to the clamping block 46 and clamp the yarn, so that during the downward movement of the slider 39 to straighten the yarn, the top position of the yarn can be kept fixed and will not move downward with the winding column 45, ensuring that the yarn can be straightened normally. During operation, when the first pushing rod 34 pushes the sliding block 50 to move upward, the sliding block 50 will push the connecting rod 49, and the connecting rod 49 pushes the moving block 48 to make it close to the clamping block 46, and the clamping block 46 is close to the yarn, and the yarn is fixed by the clamping block 46 and the moving block 48, so that the top of the yarn can be fixed in advance before the moving clamp 26 clamps the yarn, to avoid the yarn moving during the straightening process, resulting in the straightening component being unable to straighten the yarn normally.

[0043] Further, the front end of the fixed block 33 is fixedly connected with a connecting rod 36, the left side of the connecting rod 36 is fixedly connected with a clamping plate 37, the connecting rod 36 does not contact the guide rod 40, the clamping plate 37 is close to a long plate 51, the long plate 51 is fixedly connected to the electronic strong single yarn machine 1, and a scale is opened on the long plate 51, and the long plate 51 is made of transparent PP material;

[0044] During operation, when the cylinder 32 pushes the fixed block 33 to move, the connecting rod 36 fixed on the fixed block 33 will push the clamping plate 37 to move, and the clamping plate 37 will gradually approach the yarn and finally abut against the yarn. The two sides of the yarn can be clamped and fixed by the clamping plate 37 and the long plate 51. At the same time, a scale is provided on the long plate 51 to facilitate the measurement of the original length of the yarn and the length after stretching.

[0046] During operation, the rear end of the fixed plate 52 does not contact the spring 28 and the plug-in rod 29. The design of the fixed plate 52 can prevent the yarn from contacting the spring 28 when it is between the fixed clamp 23 and the movable clamp 26, thereby preventing the yarn from being entangled on the plug-in rod 29. A slot 24 is provided on the fixed clamp 23. When the movable clamp 26 clamps the yarn, the fixed plate 52 can slide into the slot 24, thereby avoiding contact with the fixed clamp 23.

[0047] Furthermore, two groups of stoppers 27 are fixedly connected to the left side of the fixing plate 52, and the two groups of stoppers 27 are respectively fitted with the top and bottom ends of the fixing fixture 23;

[0048] During operation, the stopper 27 is fixed on the fixing plate 52 and fits with the top and bottom ends of the fixing clamp 23. The stopper 27 can block the top and bottom ends of the slot 24 to reduce foreign matter or dust from entering the slot 24, causing the fixing plate 52 to be unable to move normally into the slot 24.

[0049] Furthermore, the plug-in rod 29 is designed in a T-shape as a whole, and the left side of the plug-in rod 29 fits with the left side of the fixing fixture 23;

[0050] During operation, the plug-in rod 29 is designed in a T-shape. Through the fit between the plug-in rod 29 and the fixed clamp 23, the moving distance of the movable clamp 26 can be limited, thereby preventing the movable clamp 26 from being pulled incorrectly and causing the spring 28 to be over-stretched.

[0051] Embodiment 2

[0052] See also Figure 5 As shown, comparative example 1 is another embodiment of the present invention, the extension plate 43 is L-shaped, and a vertical groove is provided on the winding post 45;

[0053] During operation, the extension plate 43 is designed to be L-shaped. When the winding post 45 moves downward to the maximum position, the bottom end of the fixing ring 42 will abut against the extension plate 43, thereby providing support for the fixing ring 42 through the extension plate 43 to prevent the fixing ring 42 and the winding post 45 from continuing to move downward. At the same time, a vertical groove is opened on the winding post 45 to facilitate the winding of the yarn on the winding post 45.

[0054] A method for detecting the tensile strength of nylon DTY low-elastic yarn for processing, the method comprising the following steps:

After the cylinder 32 is started, the first push rod 34 and the second push rod 35 will respectively push the two groups of push blocks 38 to move, and the push blocks 38 will abut against the inner wall of the abutment groove 31, and push the movable clamp 26 to move, so that the movable clamp 26 is close to the yarn until the yarn is clamped and fixed, and the movable clamp 26 will fix the yarn;

[0057] S3, adjusting the parameters of the control panel of the electronic strong single yarn machine 1, and then starting the electronic strong single yarn machine 1, the driving mechanism inside the electronic strong single yarn machine 1 will drive the bottom base 25 to move downward, so as to detect the tensile strength of the yarn.
