Description

Technical Field

[0001] The present application relates to the technical field of yarn testing, and in particular to a yarn elasticity testing device. Background Art

[0002] Yarn plays an important role in clothing, textiles, and industrial applications. Yarn quality directly impacts the performance of the final product. Yarn elasticity is a key factor in measuring yarn quality. In related technologies, yarn elasticity testing is required before processing yarn into textiles. To test yarn elasticity, one end of the yarn is fixed to a winding pole, and the other end is connected to a weighted structure, such as a weight. The yarn's elasticity is then tested by measuring its stretch and recovery lengths.

[0003] Regarding the above-mentioned related technologies, there are the following defects: in actual applications, the yarn is not only subjected to vertical downward force, but also to twisting and forces in different directions. Testing the elasticity of the yarn only by vertical downward force will reduce the testing accuracy of the yarn. At the same time, in the related technologies, when testing different types of yarns, they need to be tested one by one, which will lead to a decrease in the testing efficiency of the yarn.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0052] See also Figure 2 、 Figure 5 、 Figure 6 In some embodiments of the present disclosure, the driving mechanism 5 includes a driving outer tube 51, a driving inner tube 52, a first telescopic rod 53, a first connecting rod 56, a second connecting rod 57, a second telescopic rod 55 and a clamping member 54; the first telescopic rod 53 is provided on the working frame 1, and the movement direction of the first telescopic rod 53 is perpendicular to the height direction of the working frame 1; one side of the first connecting rod 56 is connected to the end of the first telescopic rod 53; the second telescopic rod 55 is fixedly connected to the first connecting rod 56; one side of the second connecting rod 57 is rotatably connected to the end of the second telescopic rod 55; the driving outer tube 51 is connected to the other side of the second connecting rod 57, the driving inner tube 52 is coaxially movably provided in the driving outer tube 51, and the driving inner tube 52 is connected to the other side of the first connecting rod 56; wherein the inner wall of the driving outer tube 51 has a protrusion 511, and the driving inner tube 52 has a rotating groove 521 corresponding to the protrusion 511; the clamping member 54 is provided on the driving inner tube 52, and the clamping member 54 can clamp the yarn.

[0053] Specifically, when it is necessary to apply force in the second direction to the yarn, the first telescopic rod 53 is turned on, and the first telescopic rod 53 drives the driving inner tube 52 to approach the yarn. At this time, the clamping member 54 is close to the yarn position, and the clamping member 54 is turned on. The clamping member 54 clamps the yarn, and the first telescopic rod 53 is turned on again, and the first telescopic rod 53 drives the driving inner tube 52 to move, and the movement of the driving inner tube 52 drives the clamping member 54 to move (when force is applied in the first direction, the second telescopic rod 55 does not perform telescopic movement), thereby causing the yarn to move in the second direction. In conjunction with the counterweight mechanism 6, the elastic parameters of the yarn in the second direction can be measured. Similarly, when it is necessary to apply force in the third direction to the yarn, the first telescopic rod 53 is opened, and the first telescopic rod 53 drives the driving inner tube 52 to approach the yarn, and the driving inner tube 52 drives the clamping member 54 to approach the yarn. When the clamping member 54 is close to the yarn position, the clamping member 54 is opened, and the clamping member 54 clamps the yarn. At the same time, the second telescopic rod 55 is opened, and the second telescopic rod 55 drives the second connecting rod 57 to move. The second connecting rod 57 drives the driving outer tube 51 to move. Under the action of the driving outer tube 51, the driving inner tube 52 is driven to move, and the driving inner tube 52 drives the clamping member 54 to move, thereby making the yarn move in the third direction. In conjunction with the counterweight mechanism 6, the elastic parameters of the yarn in the second direction can be measured.

[0054] As an example, the clamping member 54 includes two clamping blocks 541 and a bidirectional telescopic rod 542; the clamping block 541 is rotatably connected to the end of the driving inner tube 52 close to the yarn, wherein the axial direction of rotation of the clamping block 541 and the driving inner tube 52 is the same as the axial direction of the driving inner tube 52, and the relatively arranged clamping blocks 541 form a clamping space for the yarn; the bidirectional telescopic rod 542 is used to drive the relatively arranged clamping blocks 541 to approach or move away from each other.

[0055] In the embodiment of the present disclosure, a force in a first direction (vertical direction) can be applied to the yarn to measure the elastic parameters of the yarn; a force in a second direction (perpendicular to the plane where the working frame 1 is located) can be applied to the yarn to measure the elastic parameters of the yarn; and a force in a third direction (torsion force) can be applied to the yarn to measure the elastic parameters of the yarn. It is understandable that the elastic quality of the yarn can be judged based on the elastic parameters of the yarn in the first direction; the elastic quality of the yarn can be judged based on the elastic parameters of the yarn in the second direction; the elastic quality of the yarn can be judged based on the elastic parameters of the yarn in the third direction; of course, the parameters of the yarn can also be comprehensively judged based on the forces in the first, second, and third directions.

[0056] As an example, the clamping member 54 includes at least two clamping blocks 541 and a bidirectional telescopic rod 542. The clamping blocks 541 are rotatably connected to the ends of the driving inner tube 52. The axes of the rotation of the clamping blocks 541 and the driving inner tube 52 are perpendicular to the axis of the driving inner tube 52. The multiple clamping blocks 541 form a clamping space for the yarn. The bidirectional telescopic rod 542 is used to drive the relatively arranged clamping blocks 541 toward or away from each other. When it is necessary to test the elasticity of the yarn in the second and third directions, the bidirectional telescopic rod 542 can be adjusted to drive the clamping blocks 541 toward each other. The approaching clamping blocks 541 can clamp and secure the yarn, so that force in the second and third directions can be applied to the yarn.
