The wire withdrawing mechanism 11 comprises two wire withdrawing rollers 12 which are rotatably connected to the wire withdrawing frame 1. The two take-off rolls 12 rotate in the same direction and are arranged horizontally.

The yarn withdrawing frame 1 is provided with an adjusting mechanism 2 for adjusting the distance between two adjacent yarn withdrawing rollers 12 so as to adapt to yarn coils with different outer diameters.

Wherein, the adjusting mechanism 2 comprises a supporting seat 21 and a fixing rod 22. The wire withdrawing frame 1 is transversely provided with a supporting groove 24, and the two supporting seats 21 are slidably connected in one supporting groove 24. The take-off roll 12 is rotatably connected to a support base 21. A plurality of fixing holes 23 are formed in the outer wall of the wire withdrawing frame 1, and the plurality of fixing holes 23 are arranged along the length direction of the supporting groove 24 and beside the supporting groove 24. The fixing rod 22 passes through the supporting seat 21 and then penetrates into one fixing hole 23.

The take-off roll 12 is driven by a motor (not shown in the figure).

The yarn package is placed between two take-off rolls 12 and supported by the take-off rolls 12. When the two take-off rolls 12 rotate in the same direction, the yarn package rotates and the yarn is drawn off. As the yarn package continues to unwind, the outer diameter of the yarn package gradually decreases, allowing the take-off rolls 12 to continue to support the yarn package by drawing the distance between the take-off rolls 12 closer together. Then, the fixing rod 22 penetrates through the supporting seat 21 and then penetrates into the fixing hole 23, so that the supporting seat 21 can be positioned, and the operation is simple and convenient.

Four chutes 31 are longitudinally arranged on the adjusting frame 3, and the four chutes 31 are transversely arranged along the adjusting frame 3. A slide 32 is slidably connected to each slide groove 31, and a godet 33 is rotatably connected to each slide 32, and the godet 33 is horizontally disposed and driven by a motor (not shown). A limiting mechanism 4 is arranged between the sliding seat 32 and the adjusting frame 3.

The distance between two adjacent godet rollers 33 can be adjusted by moving the slide 32 along the chute 31. As the distance between two adjacent godets 33 increases, the yarn can be tensioned to accommodate the more elastic yarn. Similarly, the sliders 32 are used in a direction toward each other to accommodate the less elastic yarn to avoid yarn breakage.

The limiting mechanism 4 includes a support 41, a button 42, an elastic member 43, a limiting post 44 and a limiting hole 45. A plurality of limiting holes 45 are opened on the outer wall of the adjusting frame 3 and are arranged along the length direction of the sliding groove 31. The holder 41 is fixed to the slider 32. The button 42 and the limit post 44 are slidably connected to the support 41 and are connected by an elastic member 43, and the elastic member 43 is a spring. The guiding mechanism 6 is arranged between the button 42 and the limiting column 44, and the limiting column 44 is used for penetrating into a limiting hole 45.

The guide mechanism 6 includes a ramp 61, an S-block 62 and a conduit 63. The inclined blocks 61 are fixed to the inner wall of the button 42, and both ends of the S-shaped block 62 are respectively abutted against the two inclined blocks 61. The guide tube 63 is fixed on the support 41, and the limiting column 44 is connected in the guide tube 63 in a sliding manner; a slide hole 631 is opened in the conduit 63, and the slide hole 631 communicates with the inner wall of the conduit 63. The limiting column 44 is provided with an inclined hole 441; the middle part of the S-shaped block 62 is slidably connected in the inclined hole 441. The S-block 62 is slidably coupled in the slide hole 631.

When the position of the slider 32 is to be adjusted, the button 42 is pressed, the button 42 moves toward the direction close to the position-limiting post 44, the S-shaped block 62 is pressed by the inclined block 61, the S-shaped block 62 moves along the slide hole 631, and the middle part of the S-shaped block 62 presses the inner wall of the inclined hole 441, so that the position-limiting post 44 moves toward the direction close to the button 42, the elastic member 43 is further compressed, and the position-limiting post 44 is pulled out from the position-limiting hole 45. The slide 32 is moved along the slide groove 31. After the position of the slide seat 32 is adjusted, the button 42 is released, the limiting column 44 is pushed into the limiting hole 45 through the elastic force of the elastic piece 43, and the slide seat 32 can be positioned through the interference of the limiting column 44 and the inner wall of the limiting hole 45.

Four arc-shaped guide plates 7 are arranged along the circumferential direction of the godet roller 33, and the arc-shaped guide plates 7 are connected to the godet roller 33 in a sliding manner along the radial direction of the godet roller 33 through a conduction mechanism 8.

The conduction mechanism 8 comprises a support plate 81, a sliding groove 82, a sliding seat 83, a drive ring 84 and a connecting rod assembly 85, wherein the support plate 81 is fixed at the end part of the godet roller 33, and the four sliding grooves 82 are arranged on the support plate 81 and are uniformly distributed along the circumferential direction of the support plate 81; the sliding seat 83 is slidably connected to the sliding groove 82.

The drive ring 84 is mounted on the godet roll 33 and is rotatably connected to the godet roll 33 via the positioning mechanism 9. The driving ring 84 pushes the sliding seat 83 to move through the connecting rod assembly 85, and the sliding seat 83 is fixedly connected with the arc guide plate 7. The drive ring 84 is disposed coaxially with the godet roller 33 and is connected by bearings. In order to facilitate the rotation of the drive ring 84, an anti-slip groove 841 is formed on the outer wall of the drive ring 84.

The link assembly 85 includes a first link 86 and a second link 87. The first link 86 is fixed at one end to the drive ring 84 and at the other end is hinged to the second link 87. The end of the second link 87 remote from the first link 86 is hinged to the sliding seat 83.

When the driving ring 84 is rotated in the forward direction, the first link 86 drives the second link 87 to move, and then the second link 87 drives the sliding seat 83 to move, so that the sliding seat 83 moves along the sliding groove 82, and the distance between two adjacent arc guide plates 7 is increased. Similarly, the driving ring 84 rotates reversely, so that the distance between two adjacent arc guide plates 7 becomes smaller, thereby accommodating yarns of different elasticity.

When the yarn passes through the outer wall of the arcuate guide plate 7, the yarn can be further tensioned or relaxed.

Wherein, positioning mechanism 9 includes location shrinkage pool 91, reference column 92 and shell fragment 93. A plurality of positioning concave holes 91 open on the outer wall of the drive ring 84 and are evenly distributed along the axial center of the drive ring 84. Set up location shrinkage pool 91 on godet 33's outer wall, with reference column 92 sliding connection in location shrinkage pool 91 and through shell fragment 93 and the inner wall connection of location shrinkage pool 91. The positioning concave hole 91 penetrates into the positioning concave hole 91.

The driving ring 84 is rotated to overcome the friction between the positioning posts 92 and the positioning holes 91, and the distance between the sliding seats 83 is changed. After the adjustment is completed, the acting force on the driving ring 84 is stopped, so that the positioning column 92 is abutted against one positioning concave hole 91 through the elastic force of the elastic sheet 93, and the positioning of the sliding seat 83 is realized.

As described above, the yarn package is placed on the two take-off rolls 12, and the take-off rolls 12 are rotated to draw the yarn out of the yarn package. The yarn is passed through the surface of the arcuate guide plate 7 and tensioned. By adjusting the position of the slide 32 and the position of the arcuate guide plate 7, the yarn is tensioned or loosened, and over-tightening or over-loosening of the yarn is avoided. Feeding the coated coarse sand through a back roller, converging the stretched coarse sand with the yarn, and twisting the yarn together to form the yarn.
