Description

Technical Field

[0001] The present invention relates to the technical field of yarn testing, and specifically relates to a yarn strength tester. Background Art

[0002] In the spinning field, a spinning machine twists different plant fibers together into yarns. These yarns can be used to weave into cloth, and finally different products are woven from the cloth. The strength of the yarn is an important index for evaluating the quality of the yarn. The raw material quality, the technological process, the yarn structure, the yarn evenness, etc. will all affect the strength of the yarn. When the measured strength of the yarn is less than the required value for production, it indicates that there is a problem with the yarn quality. Therefore, it is necessary to test the strength of the yarn.

[0003] When the existing yarn strength tester is in use, usually a specified length of yarn is intercepted from the yarn roll, and the two ends of the yarn are fixed on the clamps at the test end of the tensile testing machine, and then the device is enabled for testing. In order to accurately control the quality of a batch of products, multiple tests are required. And for multiple tests, the staff needs to intercept and clamp the yarn, which increases the working intensity of the staff and also results in a low detection efficiency of the yarn.

[0050] Working principle: When in use, place the yarn roller 49 between the discs 48 and adjust it to a suitable position. At this time, the hydraulic cylinder A 47 can be operated. When the hydraulic cylinder A 47 operates, it will drive the adjacent discs 48 to move relatively, thereby driving the squares 481 to respectively insert into the inner cavities of the adjacent square grooves 491. At this time, the staff can pull the yarn on the yarn roller 49, make it pass between the two wire wheels, and then enter the carding frame 51 and between the two lower clamping frames 61 in sequence. At this time, the lower hydraulic cylinder B 63 can be driven to operate. When the hydraulic cylinder B 63 operates, it will drive the adjacent wire clamping plates 64 to move relatively, thereby realizing the clamping and fixing of the yarn. After the clamping and fixing is completed, the hydraulic cylinder B 63 can be stopped. Then, the servo motor 43 is operated. When the servo motor 43 operates, it will drive the reciprocating lead screw 41 to rotate through the movable shaft. When the reciprocating lead screw 41 rotates, it will drive the thread sleeve A 44 to move back and forth. When the thread sleeve A 44 moves back and forth, it will drive the n-shaped plate 46 to move back and forth through the square rod 45. At this time, the yarn roller 49 can be driven to move back and forth, which is beneficial to the uniform feeding of the yarn on the yarn roller 49, and can reduce the friction of the yarn on the yarn roller 49 during feeding. When the movable shaft rotates, it will drive the transmission rod to rotate through the belt A 723. When the transmission rod rotates, it will drive the movable bevel gear 722 to rotate. When the movable bevel gear 722 rotates, it will drive the rear threaded rod 72 to rotate through the rotating bevel gear 721, and will drive the front and rear threaded rods 72 to rotate synchronously under the transmission of the belt B 724. When the threaded rod 72 rotates, it will drive the adjacent thread sleeve B 73 to move downward. When the thread sleeve B 73 moves downward, it will jointly drive the movable seat 74 to move downward. When the movable seat 74 moves downward, it will drive the lower clamping frame 61 to move downward through the L-shaped connecting rod 77. At the same time, when the movable seat 74 moves downward, it will also drive the T-shaped pressing plate 75 to move downward. When the lower clamping frame 61 moves downward, it will drive the yarn on the yarn roller 49 to unwind and feed. When the T-shaped pressing plate 75 contacts the pressure sensor 76, it will transmit a signal to the control panel 2. The control panel 2 will control the hydraulic cylinder B 63 on the front and rear sides of the upper clamping frame 61 to operate. When the hydraulic cylinder B 63 operates, it will drive the adjacent wire clamping plates 64 to move relatively, realizing the clamping and fixing of the passing yarn. And the lower clamping frame 61 will continue to move downward, thereby tightening and testing the yarn. When the lower clamping frame 61 moves into the inner cavity of the groove and the bottom of the U-shaped connecting plate 611 moves to the top of the extrusion pushing plate 81, it will drive the pushing plate 81 to move downward. And the lower clamping frame 61 will continue to move downward. When the pushing plate 81 moves downward, it will squeeze the spring 813, and at the same time will also drive the rack plate B 82 to move downward. When the rack plate B 82 moves downward, it will drive the rotating gear 83 to rotate. When the rotating gear 83 rotates, it will drive the screw 85 to rotate through the belt C 84. When the screw 85 rotates, it will drive the thread sleeve C 86 to move forward. When the thread sleeve C 86 moves forward, it will drive the cutting knife 87 to move forward through the moving rod. When the cutting knife 87 moves forward, it will cut the yarn.The staff can observe whether the yarn breaks before cutting and record it, which is beneficial for the subsequent data statistics of the staff. After this test is completed, the clamping frame 61 below can be driven to move upward and recover, which is beneficial for the sequential test of the strength of the whole roll of yarn on the yarn roller 49, and reduces the work intensity of the staff and improves the test efficiency.
