Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 , this utility model provides two technical solutions:

[0024] Example 1

[0025] The yarn tightness controllable structure based on the spandex yarn doubling device includes a workbench 1, a yarn guide wheel is installed on the left side of the top of the workbench 1, a doubling machine 2 is installed on the right side of the top of the workbench 1, and the doubling machine 2 is a prior art and is used to doubling multiple groups of spandex yarns. A doubling ring 3 is installed on the top of the workbench 1, a thread guide mechanism 4 is provided on the top of the workbench 1, and an adjustment mechanism 5 is provided on the top of the workbench 1. The adjustment mechanism 5 includes:

[0026] The adjustment assembly 51 includes a support frame 511 mounted on the top of the workbench 1. A slide rail 512 is fixedly connected to the bottom of the inner cavity of the support frame 511. The slide rail 512 is used to slide and limit the sliding block 513. The surface of the slide rail 512 is slidably connected to the sliding block 513. The top of the sliding block 513 is rotatably connected to a rotating rod 514. One end of the rotating rod 514 causes the guide block 515 to slide through the transmission assembly 6.

[0027] The driving assembly 52 is arranged inside the support frame 511. The transmission assembly 6 includes a transmission plate 61 rotatably mounted at one end of the rotating rod 514. The top of the transmission plate 61 is fixedly connected to the bottom of the guide block 515. The two ends of the transmission plate 61 are fixedly connected to the transmission block 62. The surface of the support frame 511 is provided with a lifting groove 7. The lifting groove 7 is used to limit the upward and downward sliding of the transmission block 62, the transmission plate 61 and the guide block 515. The inner surface of the lifting groove 7 is slidably connected to the surface of the transmission block 62. The driving assembly 52 includes a driving motor 521 installed on the front side of the support frame 511. The driving motor 521 is a three-phase asynchronous motor and is connected to the external circuit through wires. One end of the output shaft of the driving motor 521 is fixedly connected to a bidirectional screw rod 522 through a coupling. The surface of the bidirectional screw rod 522 is rotatably connected to the inside of the support frame 511, and the surface of the bidirectional screw rod 522 is connected to the sliding block 513. The internal thread connection of the drive motor 521 drives the bidirectional screw rod 522 to rotate. The rotation of the bidirectional screw rod 522 causes the sliding blocks 513 on both sides to slide synchronously to the opposite or opposite sides. The sliding of the sliding block 513 causes one end of the rotating rod 514 to rotate on the top of the sliding block 513, and the other end of the rotating rod 514 rotates at the bottom of the transmission plate 61, thereby causing the transmission plate 61, the transmission block 62 and the guide block 515 to slide upward or downward synchronously, causing the transmission block 62 to slide on the inner surface of the lifting groove 7. By adjusting the height of the guide block 515, the adjustment mechanism 5 is provided, and the drive motor 521 is driven to realize the free adjustment of the height of the guide block 515, thereby facilitating the flexible adjustment of the tightness of the spandex yarn being transported, avoiding the situation that the subsequent paralleling operation is affected by the loose yarn or the yarn is tight and breaks, thereby improving the paralleling quality of the spandex yarn.

[0028] Example 2

[0029] The main differences from Example 1 are:

[0030] Based on the yarn tightness controllable structure of the spandex yarn doubling device, the lead mechanism 4 includes a lead frame 41 installed on the top of the workbench 1, a mounting groove 42 is provided on the left side of the lead frame 41, a lead plate 43 is slidably connected to the inner surface of the mounting groove 42, a lead groove 44 and a clamping groove 45 are provided on the surface of the lead plate 43, a clamping assembly 46 is provided inside the lead frame 41, and the clamping assembly 46 includes a control board 461 slidably installed inside the lead frame 41, one side of the control board 461 is fixedly connected to a clamping block 462 through a support rod, and one side of the clamping block 462 is fixedly connected to a clamping spring 46 3. The clamping spring 463 is not affected by external forces, so that the surface of the clamping block 462 is always clamped with the inner surface of the clamping groove 45. One end of the clamping spring 463 is fixedly connected to the inner wall of the lead frame 41. By providing the lead mechanism 4, multiple groups of spandex yarns are pulled to avoid entanglement during the transportation process. By providing the clamping assembly 46, the lead plate 43 can be quickly installed and removed, which improves the work efficiency when repairing or replacing the lead plate 43. At the same time, the contents not described in detail in this manual belong to the existing technology well known to those skilled in the art.

[0031] During operation, the bidirectional screw rod 522 is driven to rotate by starting the driving motor 521. The rotation of the bidirectional screw rod 522 causes the sliding blocks 513 on both sides to slide synchronously to the opposite or opposite sides. The sliding of the sliding block 513 causes one end of the rotating rod 514 to rotate on the top of the sliding block 513, and the other end of the rotating rod 514 rotates at the bottom of the transmission plate 61, so that the transmission plate 61, the transmission block 62 and the guide block 515 slide upward or downward synchronously, so that the transmission block 62 slides on the inner surface of the lifting groove 7. By adjusting the height of the guide block 515, the tightness of the spandex yarn in the transportation process can be freely adjusted to avoid If the yarn is loose and affects the subsequent paralleling operation or the yarn is tight and breaks, after the work is completed, the control panels 461 on both sides can be pressed to drive the support rod and the clamping block 462 to slide synchronously to the opposite sides, so that the clamping spring 463 is compressed, and the clamping block 462 slides out of the clamping groove 45, and then the lead plate 43 is pulled out, so as to achieve rapid disassembly of the lead plate 43, which is convenient for maintenance or replacement. When it needs to be installed, the lead plate 43 can be directly inserted into the installation groove 42. Under the influence of the elasticity of the clamping spring 463, the clamping block 462 will always remain in a clamping state with the inside of the clamping groove 45.
