Description

Technical Field

[0001] This utility model relates to the field of yarn processing technology, and in particular to a yarn braiding machine. Background Technology

[0002] Yarn is a continuous, slender body made by twisting textile fibers. As an intermediate material connecting fibers and fabrics, it is widely used in the textile and apparel industry. Its definition covers traditional staple fiber yarn and filament yarn. According to raw materials, it can be divided into natural fiber yarn (cotton / linen), chemical fiber yarn (polyester / nylon), and blended yarn, etc.

[0003] A yarn braiding machine is a mechanical device used to weave yarn into fabric. It mainly includes warp knitting machines, sewing machines, and weaving machines. When using a yarn braiding machine, a winding mechanism is installed above the braiding mechanism to wind up the woven yarn. To facilitate easy removal of the wound yarn, the winding rollers are often arranged with multiple support shafts around the circumference to allow sufficient clearance for material handling. However, because the multiple support shafts are fixedly installed, the yarn inevitably needs to loosen during winding, affecting the winding effect and causing the woven yarns to become entangled. Furthermore, the fixed support shafts result in a fixed winding radius for the wound yarn, leading to low adaptability; that is, the overall thickness of the wound yarn is limited and its limitations are too high. Therefore, we propose a yarn braiding machine. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example Reference Figures 1-4 A yarn braiding machine includes an operating table 1, with support legs 2 installed at the bottom corners of the operating table 1, a braiding mechanism on the top of the operating table 1, and a winding mechanism above the braiding mechanism. The winding mechanism is fixed to the operating table 1 by a support frame 11.

[0019] like Figure 1 and Figure 2As shown, the weaving mechanism includes a turntable 3. A first rotating shaft 4 is coaxially mounted on the bottom of the turntable 3. The first rotating shaft 4 passes through the operating table 1 and is connected to a first drive motor 5. The first drive motor 5 is fixed to the bottom of the operating table 1, and the first rotating shaft 4 is rotatably connected to the operating table 1. A support base 10 is coaxially mounted on the top of the turntable 3. The support base 10 has a cylindrical structure. Multiple feed racks 8 are provided along the top edge of the turntable 3, and a guide rack 9 is provided on the top of the feed racks 8. In use, the yarn to be woven can be placed on the feed racks 8, and one end of the yarn can be passed through the guide rack 9 and fixed on the winding mechanism. As the turntable 3 rotates, the yarn twisted into a strand on the winding mechanism can complete the weaving operation of multiple yarns under winding.

[0020] In order to improve the stability of the turntable 3 when it rotates, a ring-shaped first slide rail 6 is provided coaxially at the bottom of the turntable 3. The first slide rail 6 is fixed on the operating table 1. Several first sliders 7 are slidably installed on the first slide rail 6 at intervals. The first sliders 7 are fixed to the turntable 3, and support the turntable 3 without affecting its rotation, thereby improving the rotational stability of the turntable 3.

[0021] like Figure 3 and Figure 4 The winding mechanism includes a rotating seat 12, a second rotating shaft 13 connected to the middle of one side of the rotating seat 12, and a second drive motor 14 installed at the other end of the second rotating shaft 13. The second drive motor 14 is fixed on the support frame 11 and provides power for the rotation of the rotating seat 12.

[0022] Furthermore, a ring-shaped second slide rail 15 is provided on the side of the rotating seat 12 near the second drive motor 14. The second slide rail 15 is mounted on the support frame 11. Several second sliders 16 are slidably mounted on the second slide rail 15 at intervals. The other end of the second sliders 16 is fixed to the rotating seat 12. While not affecting the rotation of the rotating seat 12, a connection is established between the rotating seat 12 and the support frame 11, so as to provide additional support for the rotating seat 12 and the support frame 11 except for the second rotating shaft 13, thereby improving the rotational stability of the rotating seat 12.

[0023] The rotating seat 12 is a hollow cylindrical shell. Multiple spaced strip grooves 17 are provided on the side of the rotating seat 12 away from the second drive motor 14. The strip grooves 17 are arranged along the axial direction of the rotating seat 12. Multiple lead screws 18 are provided inside the rotating seat 12. The lead screws 18 correspond one-to-one with the strip grooves 17. One end of the lead screw 18 is rotatably connected to the inner wall of the rotating seat 12, and the other end of the lead screw 18 is rotatably mounted on the connecting seat 29. The connecting seat 29 is fixed to the inner wall of the rotating seat 12. A transmission mechanism is provided between the lead screws 18 to drive their rotation. A drive mechanism is provided on one of the lead screws 18.

[0024] The drive mechanism includes a worm gear 22, which is located outside the rotating seat 12 and coaxially fixed with one of the lead screws 18. A worm 23 is meshed on one side of the worm gear 22, and a fixed seat 24 is rotatably mounted on the end of the worm 23. The fixed seat 24 is fixed to the outer wall of the rotating seat 12. A handle 25 is installed on one end of the worm 23. In use, the operator can hold the handle 25 to rotate the worm 23, thereby driving the lead screw 18 coaxially connected to the worm gear 22 to rotate. With the help of the transmission mechanism, the rotation of the lead screw 18 can drive the lead screw 18 to rotate synchronously. In actual use, the transmission between the worm gear 22 and the worm 23 can also lock the lead screw 18, that is, the worm gear 22 cannot rotate the worm 23.

[0025] Furthermore, the transmission mechanism includes a first bevel gear 19 coaxially mounted on one end of the lead screw 18 near the connecting seat 29, a second bevel gear 20 meshing on one side of the first bevel gear 19, and a connecting shaft 21 coaxially mounted on the second bevel gear 20. The connecting shaft 21 is rotatably mounted on the connecting seat 29 to achieve synchronous rotation of all lead screws 18.

[0026] As all the lead screws 18 rotate synchronously, a movable seat 26 is connected to the lead screw 18 via a threaded nut. One end of the movable seat 26 passes through the strip groove 17 and a support shaft 27 is vertically mounted on its end face. The movable seat 26 can reciprocate linearly along the length of the strip groove 17, thereby adjusting the size of the circumference enclosed by all the support shafts 27. This allows for adjustment of the winding radius of the yarn during weaving according to actual usage, and also enables the support shafts 27 to be moved outward at the start of winding to achieve yarn tensioning, ensuring that the yarn winding effect does not result in tangling between yarns.

[0027] Furthermore, both sides of the movable seat 26 and the inner wall of the strip groove 17 are smooth surfaces, and the side of the movable seat 26 and the inner wall of the strip groove 17 are fitted with a clearance, which limits the linear movement of the movable seat 26 and ensures the stability of the movable seat 26 when it moves under the rotation of the lead screw 18.

[0028] Furthermore, one end of the support shaft 27 is threaded to the movable seat 26, and a limiting plate 28 is threaded to the other end of the support shaft 27 to limit the yarn wound on the support shaft 27 and prevent the yarn from falling off the support shaft 27. In addition, since the support shaft 27 is threaded to the movable seat 26, it is convenient to add or reduce the number of support shafts 27 according to the winding radius to ensure that there is sufficient distance between adjacent support shafts 27 so as to pick up the yarn after winding.

[0029] Specifically, a control box 30 is installed on the top of the side of the operating table 1 away from the support frame 11. The control box 30 contains a controller, which is connected to the second drive motor 14 and the first drive motor 5 via wires. In actual use, the controller is one of a PLC logic controller, a control motherboard, or a control host, and controls the operation of the knitting machine. In addition, a touch screen is installed on the outer wall of the control box 30. The touch screen is connected to the controller via wires to operate the knitting machine.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
