DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme of the utility model carry out clearly, complete description, and the advantage is more clear and distinct, the following combining with the figure to the utility model embodiment carries out further detailed explanation.Should understand, the specific embodiment described here is a part of the embodiment of the utility model, instead of all the embodiments, only use to explain the embodiment of the utility model, and does not use to limit the embodiment of the utility model, all other embodiments obtained by the ordinary skill in the art without making the creative labor belong to the scope of the protection of the utility model.

[0025] Embodiment one, please refer to Figures 1-6 The utility model provides a kind of technical scheme: a traction device for yarn production, traction device includes: fixed crossbeam 1.

[0026] Specifically, lifting guide rail 2 is arranged below fixed crossbeam 1, lifting guide rail 2 itself is placed horizontally, and can move up and down in vertical direction, a plurality of rotating shafts 5 are rotatably installed on one side of lifting guide rail 2, the relative position of rotating shaft 5 and lifting guide rail 2 remains fixed, rotating shaft 5 can only rotate on one side of lifting guide rail 2, so that rotating shaft 5 can be lifted along with lifting guide rail 2 when lifting guide rail 2 lifts, rack 3 is slidably installed in the inner cavity of lifting guide rail 2, rack 3 slides along the length direction of lifting guide rail 2, special-shaped tooth ring 4 is sleeved on the upper outer side of rotating shaft 5, and special-shaped tooth ring 4 is in meshing transmission with rack 3, rack 3 drives special-shaped tooth ring 4 to rotate when sliding, in turn drives rotating shaft 5 to rotate, "J" shaped traction hook 6 is fixed to the lower end of rotating shaft 5, rotating shaft 5 can drive traction hook 6 to rotate when rotating, as shown in Figure 1 It can be known that a plurality of traction hooks 6 and a plurality of yarns are sequentially and spacedly distributed, when traction hook 6 has not rotated, lifting guide rail 2 can drive a plurality of traction hooks 6 to pass through the gap between a plurality of yarns respectively when descending, then rotating traction hook 6, lifting guide rail 2 is lifted again, a plurality of traction hooks 6 can pull a plurality of yarns out one by one, so that winding between adjacent yarns is avoided.

[0027] Secondly, a plurality of guide sliding grooves 42 are arranged in the inner side wall of special-shaped tooth ring 4 in annular array, guide boss 53 corresponding to a plurality of guide sliding grooves 42 is fixed to the upper outer side wall of rotating shaft 5, as shown in Figure 5 AndFigure 6 As shown, the special-shaped tooth ring 4 can slide up and down along the length direction of the rotating shaft 5, so the worker can control the special-shaped tooth ring 4 to separate from the rack 3 by controlling the special-shaped tooth ring 4 to move up alone, at this time, the rack 3 will not drive the special-shaped tooth ring 4 to rotate when sliding, and further cannot drive the rotating shaft 5 and the traction hook 6 corresponding to the special-shaped tooth ring 4 to rotate, therefore, the worker can control the traction of the specified yarn by controlling the engagement of the special-shaped tooth ring 4 and the rack 3, thereby ensuring the accuracy of the yarn traction.

[0028] In order to limit the rotation angle of the special-shaped tooth ring 4, the present application also has a tooth groove 41 formed on the side surface of the special-shaped tooth ring 4, and the central angle of the tooth groove 41 is ninety degrees, the teeth on the side surface of the rack 3 are in engagement transmission with the special-shaped tooth ring 4 through the tooth groove 41, and when the rack 3 drives the special-shaped tooth ring 4 to rotate, the special-shaped tooth ring 4 can only rotate a maximum of ninety degrees, that is, the maximum rotation angle of the traction hook 6 is ninety degrees, when the traction hook 6 is not rotated, the hook at the lower end of the traction hook 6 can pass through the gap between the adjacent two yarns, when the traction hook 6 is rotated by ninety degrees, the traction hook 6 rises to hook the yarn, in addition, one side of the rack 3 extends out of the inner cavity of the lifting guide rail 2 and engages with the tooth groove 41, as shown in Figure 3 and Figure 4 As shown, although the special-shaped tooth ring 4 is in engagement transmission with the rack 3 through the tooth groove 41, the special-shaped tooth ring 4 can move up and down alone and will not be hindered by the lifting guide rail 2, so the worker can control the relative position between the special-shaped tooth ring 4 and the rack 3 at any time.
