7. The textile yarn elasticity testing device of claim 1, wherein the hook frame has a bottom portion of a frame-shaped structure and a top portion of a hook structure, and the hook portion of the hook frame is fitted to an inside of the threading hole.
8. The textile yarn elasticity testing device of claim 1, wherein a supporting groove is formed in the top of the lifting plate, a buffering sliding shaft is fixedly connected inside the supporting groove, a movable plate is arranged on the top of the buffering sliding shaft, and a pressure sensor is arranged at the bottom of the movable plate.
9. The textile yarn elasticity testing device of claim 8, wherein the outer surface of the movable plate is slidably connected with the inner surface of the supporting groove, and the hook frame is installed above the movable plate.
10. A textile yarn elasticity testing method is characterized by comprising the following steps:
s1, the textile yarns transversely penetrate into the threading holes to keep normal conveying and straightening, during detection, the rotating motor is started in the forward direction, the rotating motor drives the screw rod to rotate, the screw rod drives the connecting plate to move upwards when rotating, and the connecting plate drives the lifting plate and the hook frame to move upwards;
s2, when the hook part of the hook frame is higher than the top of the yarn, the rotating motor is turned off, the expansion piece is started, the expansion piece drives the linkage frame to contract, the linkage frame drives the movable pressure to axially press the inside of the expansion groove, meanwhile, the hook frame on the lifting plate can be synchronously driven to move towards the upper part of the yarn, and the hook frame is kept inside the movable groove when moving;
s3, when the hook frame moves to the position right above the yarn, the movable pressing shaft is transversely inserted into the threading hole to compress and limit the yarn, and the hook frame is hooked on the surface of the yarn;
s4, reversely starting the rotating motor, driving the screw rod to reversely rotate by the rotating motor, driving the connecting plate to move downwards by the screw rod, driving the lifting plate to move downwards by the connecting plate, enabling the hook frame to form a downward pulling force on the yarn, and closing the rotating motor along with the hook frame being separated from the surface of the lifting plate;
and S5, the rotating motor is started in the positive direction, so that the lifting plate moves upwards, the hook frame hung in the step S is lifted upwards, and the upward shrinkage and resetting of the yarn are formed after the hook frame is lifted upwards, so that the elastic recovery of the yarn can be tested.
