Description

Technical Field

[0001] This utility model relates to the field of drawing device technology, specifically to a drawing component with built-in positioning function. Background Technology

[0002] Covered yarn processing is a textile process that involves covering one or more yarns onto another yarn or filament to form a composite yarn with specific properties. In the covered yarn processing, yarn stretching is a key step. Stretching and deforming the yarn improves its performance and structure, thereby enhancing the production quality of the covered yarn.

[0003] Chinese utility model patent CN220149732U discloses a roller drafting assembly, which includes "a U-shaped plate and multiple hollow rods movably connected to both sides inside the U-shaped plate, with a rear roller fixed to the outer wall of the multiple hollow rods, multiple vent pipes fixedly installed through one side of the U-shaped plate, one end of the multiple vent pipes extending into the interior of the multiple hollow rods, and a diversion sealing can being fixedly installed at the other end of the multiple vent pipes"; however, this drafting assembly does not have a limiting structure, and when the yarn is tensioned in the drafting process, the high-speed moving yarn is prone to tilting and deflection on the rotating roller, resulting in the yarn tangling and knotting, affecting the drafting efficiency and stability, and lacking practicality. Utility Model Content

[0017] The configuration is further defined as follows: the two screws on both sides are respectively connected to the worm gear on the left side of the corresponding worm through their respective turbines, and the two screws on both sides are respectively connected to the worm gear on the right side of the corresponding worm through their respective turbines.

[0018] By adopting the above technical solution, the worm gears at both ends of the two worms are meshed with the corresponding turbines, thereby achieving the effect of simultaneously driving the two screws (screw one and screw two) on both sides.

[0019] To achieve the effect of limiting and positioning the yarn:

[0020] The U-shaped limiting ring is further configured such that its inner wall is slidably connected to the outer wall of the pressure ring.

[0021] By adopting the above technical solution, the pressure ring is slidably inserted into the corresponding U-shaped limiting ring, thereby achieving the effect of limiting and positioning the yarn.

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0035] Please see Figures 1 to 7 The traction assembly with built-in positioning function includes a frame 1. The frame 1 is equipped with two screws 1 2 and two screws 2 3. The outer walls of the two screws 1 2 and the two screws 2 3 are movably connected to the inner walls of the two connecting rods 4. The two screws 1 2 and the two screws 2 3 are movably connected to the drive assembly 5.

[0036] Two screws 1, 2 are located on the front and rear sides of the frame 1 near the left end, respectively; two screws 2, 3 are located on the front and rear sides of the frame 1 near the right end, respectively.

[0037] The front and rear side walls of the frame 1 are symmetrically provided with a number of shaft holes 11, and the inner walls of the shaft holes 11 on both sides are rotatably connected to the outer walls at both ends of the limiting roller 6.

[0038] The two connecting rods 4 are symmetrically provided with several shaft holes 41 inside, and the two ends of the two connecting rods 4 are provided with screw holes 42. The inner walls of the shaft holes 41 on both sides are rotatably connected to the outer walls of the two ends of the pressure roller 7.

[0039] The inner wall of the screw hole 42 at the left end of each connecting rod 4 is threaded to the outer wall of the corresponding screw rod 2, and the inner wall of the screw hole 42 at the right end of each connecting rod 4 is threaded to the outer wall of the corresponding screw rod 3.

[0040] The drive assembly 5 includes two worm gears 51, which are located on the front and rear sides of the frame 1 near the top. Each worm gear 51 has a spiral tooth 511 at both ends. A rotating wheel 52 is fixedly connected to the right end of each worm gear 51. The two rotating wheels 52 are connected by a belt 53. The right side wall of one of the rotating wheels 52 is connected to the output end of a servo motor 54 fixedly mounted on the side wall of the frame 1.

[0041] Several U-shaped limiting rings 61 are fixedly connected to the outer side wall of the limiting roller 6, and several pressure rings 71 are fixedly connected to the outer side wall of the pressure roller 7. The several U-shaped limiting rings 61 and several pressure rings 71 are set in correspondence.

[0042] In this embodiment, as Figure 1 and Figure 3 As shown, screw 2 is equipped with turbine 21 near the top, and screw 3 is equipped with turbine 31 near the top.

[0043] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, the two screws 2 are respectively connected to the worm gear 51 on the left side of the corresponding worm 51 through their respective turbines 21, and the two screws 3 are respectively connected to the worm gear 51 on the right side of the corresponding worm 51 through their respective turbines 31.

[0044] In this embodiment, as Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the inner wall of the U-shaped limiting ring 61 is slidably connected to the outer wall of the pressure ring 71.

[0045] In this embodiment, as Figure 1 , Figure 5 and Figure 6 As shown, each pressure roller 7 is located directly above the corresponding limiting roller 6, and the set of pressure rollers 7 and limiting rollers 6 on the left end is lower than the pressure rollers 7 and limiting rollers 6 on the right.

[0046] The drawing assembly with built-in positioning function works as follows:

[0047] First, the yarns are passed through the U-shaped limiting rings 61 on the outer wall of the limiting roller 6 located on the left end. Then, the yarns are passed through the subsequent limiting rollers 6 in sequence and extend from the right end of the frame 1 to achieve the effect of yarn positioning and packaging. The servo motor 54 drives one rotating wheel 52 to rotate, and the belt 53 drives another rotating wheel 52 to rotate synchronously, thereby simultaneously driving the worm gears 51 on both sides to rotate.

[0048] The worm gears 511 at both ends of the worm 51 mesh with the turbine 21 and the turbine 31 respectively, thereby synchronously driving the screw 2 and the screw 3 to rotate. The rotation of the screw causes the connecting rods 4 on both sides to move up and down along the screw direction through the screw hole 42, thereby driving the pressure roller 7 to adjust its height.

[0049] The pressure ring 71 on the outer wall of the pressure roller 7 can be slidably inserted into the corresponding U-shaped limiting ring 61 to achieve the limiting and fixing of the yarn. By adjusting the height of the connecting rod 4, the depth of the pressure ring 71 inserted into the U-shaped limiting ring 61 can be controlled, thereby precisely adjusting the tightness of the yarn.

[0050] During the yarn drafting process, the pressure roller 7 rotates within the connecting rod 4 through the shaft hole 11, and the limiting roller 6 rotates within the frame 1 through the shaft hole 41. This structure realizes the functions of automatic yarn positioning, adjustable pressure, and smooth drafting.

[0051] The servo motor 54 is model 1PM4105-2LF86-1 CS1, which is a known prior art.
