[0002] Patent CN220664514U provides a lawn curling yarn winding machine. In this patent, a reciprocating rod assembly is placed above the winding drum. The reciprocating rod assembly is heavy, and as the diameter of the winding drum increases, the angle of the reciprocating rod assembly also changes. That is, initially, the weight of the reciprocating rod assembly presses on the winding drum, but as the diameter increases, the pressure exerted on the winding drum by the weight of the reciprocating rod assembly decreases, causing the pressure on the curling yarn to change, thus affecting the winding quality of the curling yarn. Therefore, in order to ensure the forming quality of the curling yarn, this constant tension winding machine was designed. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1 to 5This utility model provides a technical solution: a constant tension winding machine, including a frame 1. A guide wheel 3, a traction roller 4, and a traction inclined roller 5 are sequentially arranged on the frame 1. The guide wheel 3 is rotatably connected to the frame 1. A motor is connected to the surface of the frame 1, and the output end of the motor is connected to the traction roller 4. A motor cover is fixed to the surface of the motor. The traction inclined roller 5 is rotatably connected to the motor cover. A tension rod 6 is rotatably connected to the lower part of the traction inclined roller 5 on the frame 1. A reciprocating conveying assembly 7 is arranged below the tension rod 6. The reciprocating conveying assembly 7 is used to reciprocately wind the yarn onto the winding roller 81. A guide wheel 9 is arranged on the side of the tension rod 6. The guide wheel 9 is used to guide the yarn and introduce it into the reciprocating conveying assembly 7. A waist-shaped groove is opened on the frame 1, and the reciprocating conveying assembly 7 is inserted into the waist-shaped groove. A cylinder 74 is fixed on the back of the machine. The conveying end of the cylinder 74 is connected to the reciprocating conveying assembly 7. The extension and retraction of the cylinder 74 controls the position of the reciprocating conveying assembly 7 in the waist-shaped groove. A take-up roller 81 is rotatably connected to the frame 1. The yarn is wound sequentially around the guide wheel 3, traction roller 4, traction inclined roller 5, tension rod 6, guide wheel 9, reciprocating conveying assembly 7, and take-up roller 81. The tension rod 6 is used to adjust the tension of the yarn to ensure the quality of yarn winding. The take-up roller 81 is located on the side of the reciprocating conveying assembly 7, and when winding, the take-up roller 81 is attached to the reciprocating conveying assembly 7 to increase the pressure on the yarn and improve the winding quality. Compared with the previous winding machine, the weight of the reciprocating conveying pressure plate applied to the yarn is reduced, which further ensures the constant tension of the yarn and improves the winding quality.

[0016] like Figures 6 to 8 As shown, the reciprocating conveyor assembly 7 includes a panel 73, a cylinder 74 connected to the lower end of the panel 73, one end of the cylinder 74 connected to the frame 1, the telescopic part of the cylinder 74 connected to the reciprocating conveyor assembly 7, and the output end of the cylinder 74 can control the movement of the reciprocating conveyor assembly 7. The yarn on the reciprocating conveyor assembly 7 is in close contact with the take-up roller 81. A slider connecting plate 72 is connected to the lower end of the panel 73. A slider is fixed on the side of the slider connecting plate 72. A slide rail 71 is slidably connected to the side of the slider. The slide rail 71 is fixed on the frame 1. The movement of the reciprocating conveyor assembly 7 is guided by the slide rail 71. As the diameter of the take-up roller 81 increases, a thrust is applied to the reciprocating conveyor assembly 7, causing the reciprocating conveyor assembly 7 to move to one side. This ensures that the yarn is clamped between the reciprocating conveyor assembly 7 and the take-up roller 81, improving the winding quality of the curved yarn.

[0017] like Figure 7 and 8As shown, side plates 75 are fixed to both ends of the panel 73. An upper roller 76 and a side roller 77 are rotatably connected between the side plates 75 via pins. The upper roller 76 is used to guide the yarn, and the side roller 77 is used to provide pressure to the wound yarn. A mounting plate 712 is connected to the side of the side plate 75. Rollers 78 are rotatably connected to both ends of the mounting plate 712. A motor is also mounted on the mounting plate 712. A synchronous pulley is connected to the output end of the motor. A synchronous belt is also connected between the synchronous pulley and the roller 78. A guide nozzle 711 is connected to the synchronous belt. The reciprocating motion of the synchronous belt is controlled by the rotation of the motor, so that the guide nozzle 711 reciprocates and drives the yarn to reciprocate and evenly wind on the take-up roller 81.

[0018] like Figure 7 and 8 As shown, a reciprocating guide rail 79 is bolted to the mounting plate 712, and a sliding block 710 slides on the reciprocating guide rail 79. The sliding block 710 is located below the synchronous belt. The wire nozzle 711 and the sliding block 710 are respectively clamped on the upper and lower ends of the synchronous belt. The reciprocating motion of the wire nozzle 711 is guided by the sliding of the reciprocating guide rail 79 and the sliding block 710, making the reciprocating motion smoother.

[0019] A rotating plate 2 is mounted on the frame 1. A rotating gear 21 is connected to the back of the rotating plate 2 via a pin. Multiple evenly distributed limiting wheels are fixed on the outer edge of the rotating gear 21, restricting the rotating gear 21 to rotate on the back of the frame 1. A central roller 82 is rotatably connected to the back of the rotating gear 21. Four synchronous pulleys are fitted and fixed on the central roller 82. A drive motor 83 is also mounted on the back of the frame 1. The output end of the drive motor 83 is also connected to synchronous pulleys. The synchronous pulleys are connected to each other by a synchronous belt. The drive motor 83 controls the rotation of the central roller 82. A take-up roller 81 is also rotatably connected to the back of the rotating gear 21. The take-up roller 81 and the central roller 82 rotate together via a synchronous belt and synchronous pulleys. The central roller 82 drives the take-up rollers 81 on both sides to rotate, winding up the yarn.

[0020] A side gear 84 is rotatably connected to the back of the frame 1. The side gear 84 meshes with the rotating gear 21. The side gear 84 is driven by a motor. The rotation of the side gear 84 controls the rotation of the rotating gear 21, which in turn drives the rotating plate 2 to rotate. This causes the two take-up rollers 81 on the rotating plate 2 to exchange positions, rotate the take-up roller 81 that is winding the thread to the other side, cut the thread, and rewind the thread onto the take-up roller 81 on the other side, thus achieving automatic roll changing.

[0021] like Figure 3 and 4As shown, a tensioning wheel 85 is also connected to the back of the rotating gear 21. The tensioning wheel 85 is pressed against the synchronous belt between the take-up roller 81 and the center roller 82. A mounting plate is connected to the lower end of the tensioning wheel 85. A waist hole is opened on the mounting plate, and a bolt is connected in the waist hole to fix the tensioning wheel 85. By adjusting the height of the waist hole, the height of the tensioning wheel 85 can be adjusted to further control the tension of the synchronous belt and ensure that the synchronous belt is in a taut state.

[0022] The tension rod 6 includes a central shaft 68 inserted into the frame 1. One end of the central shaft 68 is rotatably connected to the back of the frame 1 via a bearing seat 67 and a bearing. A tension motor 66 is connected to the end of the central shaft 68. A housing 64 is also sleeved on the central shaft 68 and fixed to the frame 1. A rotating housing 63 is inserted into the housing 64 and connected to the housing 64 via a spring 65. The rotating housing 63 is bolted to the central shaft 68, allowing the rotating housing 63 and the central shaft 68 to rotate together. A transmission rod 62 is fixed to the end of the rotating housing 63. A tension wheel 61 is rotatably connected to the other end of the transmission rod 62 via a bearing. The tension wheel 61 guides the yarn. The rotation of the central shaft 68 is controlled by the tension motor 66. The swing angle of the transmission rod 62 is adjusted according to the change in yarn tension to ensure that the yarn is under constant tension and improve the winding quality.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
