Description

Technical Field

[0001] The utility model relates to the technical field of elastic testing of knitted yarns, and particularly relates to an elastic testing device for high-elastic composite knitted yarns. Background Technique

[0002] Knitted yarn is the yarn used for hand knitting or producing knitted fabrics. It is divided into cotton knitted yarn, wool knitted yarn, and blended yarn according to raw materials, and into carded knitted yarn and combed knitted yarn according to the spinning system. Usually, the raw materials used are of good quality, the yarn is smooth, the twist is small, and the hand feeling is soft. Composite knitted yarn is a structure in which two different fibers are intertwined with single yarns or filaments similar to the structure of ply yarn. When producing high-elastic composite knitted yarns, it is often necessary to test their elasticity.

[0003] The "Yarn Elasticity Testing Device" disclosed in its application number "202021581221.X" "comprises: a device base, a support base, a test support, a fixed support, and weights; the support base is fixed on the device base, the lower part of the test support is rotatably fixed on the support base, and the fixed support is foldably fixed on the top of the test support; a marking scale is provided on the test support; a yarn winding column and a wire pressing assembly are provided on the fixed support; wherein, when the test support and the fixed support are in a vertical state, the wire pressing assembly and the marking scale are located below the yarn winding column".

[0026] In this embodiment, preferably, the second driving component 17 includes a second motor 1701. The output shaft of the second motor 1701 is connected with a worm 1702. Both sides of the worm 1702 are meshed and connected with worm wheels 1703. The worm wheels 1703 are fixedly connected with the middle part of the support shaft 15. The top end of the worm 1702 is rotationally connected with the inner wall of the top end of the base 13. By driving the worm 1702 with the second motor 1701, the two worm wheels 1703 are driven to rotate in opposite directions to each other, so that the two support shafts 15 can rotate in opposite directions to each other, and the auxiliary support legs 16 can be extended and retracted.

[0027] In this embodiment, preferably, a positioning rod 2 is fixedly arranged at the bottom of one side of the frame 1. One end of the high-elastic composite knitting yarn can be positioned through the positioning rod 2. Two baffle plates 11 are fixedly arranged at the top of one side of the frame 1. The baffle plates 11 can prevent the sliding table 3 from falling off. A display screen 12 is fixedly installed at the top of one side of the frame 1. The display screen 12 is electrically connected with the pressure sensor 6. The pressure sensor 6 can be read through the display screen 12. The top end of the base 13 is welded to the bottom end of the frame 1. There is a maintenance opening on one side of the base 13. One side of the maintenance opening is fixedly connected with a cover plate 14 through screws. By opening the cover plate, the inside of the base 13 can be maintained and repaired.

[0028] During use, first, the base 13 is erected on the ground. Then, the second motor 1701 of the second driving component 17 is used to drive the worm 1702. The worm 1702 drives the two worm wheels 1703 to rotate in opposite directions to each other, so that the two support shafts 15 can rotate in opposite directions to each other, and the four auxiliary support legs 16 can be unfolded simultaneously. After the auxiliary support legs 16 are unfolded, the worm 1702 and the worm wheels 1703 can achieve self-locking of the support shaft 15, increasing the support area of the base 13. Then, both ends of the high-elastic composite knitting yarn are fixed through the positioning rod 2 and the pull rod 4 respectively. Finally, the first motor 801 of the first driving component 8 is used to drive the lead screw 802. The threaded sleeve converts the rotational motion of the lead screw 802 into the linear motion of the sliding plate 803. The support rod 805 can drive the sliding table 3 to rise. The sliding table 3 can stretch the knitting yarn through the pull rod 4. By observing the moving value of the sliding table 3 through the scale 10, the elasticity of the knitting yarn can be calculated; [[ID= nine]]

[0029] During the test, the pressure sensor 6 can detect the tensile force during stretching and transmit the detected data to the display screen 12 for the convenience of the tester to read the data, and the tensile resistance of the knitting yarn can be tested. After the test, the motor 801 drives the lead screw 802 in the reverse direction to lower the height of the sliding table 3 and contract it. Then, the motor 1701 drives the worm 1702 in the reverse direction to contract the auxiliary support leg 16, which can reduce its volume and facilitate its storage and movement.

The scope of the present invention is defined by the appended claims and their equivalents.
