Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a yarn winding guiding mechanism. Background Technology

[0002] The automatic winding machine's yarn winding mechanism rewinds the bobbins or skeins from the spinning section into larger-capacity bobbins for subsequent processing and use. This process not only changes the yarn's package shape but also uses a yarn clearing device to inspect and remove defects and impurities from the yarn, such as thick places, thin places, double yarns, weak twist yarns, and neps, thereby improving yarn quality and providing high-quality yarn for subsequent processes. The yarn winding mechanism typically includes components such as a yarn clearer, a tensioner, and a guide tube. The tensioner controls the tension during yarn winding, and the guide tube guides the yarn into the bobbin.

[0003] In existing automatic winding machines, the yarn guiding mechanism is usually fixed in a fixed position. When a yarn spool reaches the required diameter, the fully wound spool needs to be removed, replaced with a new empty spool, and the yarn needs to be wound onto the new empty spool through the guiding mechanism before the winding work can continue. This structure affects work efficiency and requires frequent operation by staff, which consumes a lot of time and manpower. Utility Model Content

[0004] To address the problem in existing technologies where the yarn winding guide mechanism is fixed and cannot be flexibly and seamlessly switched to a new yarn winding cylinder, this utility model provides a yarn winding guide mechanism.

[0005] The technical solution adopted in this utility model is:

[0006] A yarn winding guide mechanism includes a yarn winding mechanism, a guide mechanism, and a yarn winding bracket, wherein the guide mechanism is disposed on the yarn winding bracket, and the yarn winding mechanism is disposed on one side of the yarn winding bracket;

[0007] The yarn winding mechanism includes a yarn winding drum and an electric motor. The electric motor is connected to the yarn winding drum via a motor shaft. The yarn winding drum is located inside the yarn winding bracket.

[0008] The guiding mechanism includes a movable guiding bracket and a guiding wheel mounted on the guiding bracket. The movable guiding bracket has "I"-shaped guiding sliders at both ends. The yarn winding bracket has a horizontally positioned guiding slide rail, which slides in cooperation with the guiding sliders of the movable guiding bracket.

[0009] Furthermore, pressure roller brackets are connected to both sides of the guide wheel on the movable guide bracket, and pressure roller groups are provided on the pressure roller brackets;

[0010] The pressure roller assembly includes an upper pressure roller and a lower pressure roller, with a gap between the upper and lower pressure rollers for yarn to pass through. Both the upper and lower pressure rollers are rotatably connected to the pressure roller bracket.

[0011] Furthermore, a roller groove is provided at the position of the guide rail on the yarn winding bracket, and a traveling roller is connected to the side of the guide slider opposite to the roller groove, and the traveling roller cooperates with the roller groove.

[0012] Furthermore, a winding support mechanism is provided on the side of the yarn winding bracket opposite to the yarn winding mechanism. The winding support mechanism includes a drive cylinder and a support head. The drive cylinder is connected to a piston rod, the piston rod is connected to a support rod, the support head is fixedly connected to the end of the support rod, and the support rod is rotatably connected to the piston rod.

[0013] The support head is used to extend the piston rod to contact the yarn winding drum and support the rotation of the yarn winding drum.

[0014] Furthermore, multiple inner wall support components are evenly arranged on the side of the support head around the rotation axis of the support rod. The inner wall support components include an inner wall support seat and an inner wall support block telescopically disposed within the inner wall support seat. A pneumatic device is externally connected to the inner wall support seat.

[0015] Furthermore, a rotary bearing is connected between the support rod and the piston rod, and a cylinder mounting platform is connected to the bottom of the drive cylinder.

[0016] The beneficial effects of this utility model are:

[0017] This utility model's yarn winding guide mechanism achieves switchable guide positions and seamless transitions to a new yarn winding bobbin by incorporating guide wheels that move with the movable guide bracket. When the currently winding bobbin reaches the specified winding size, the drive mechanism of the movable guide bracket drives the guide slider to slide along the guide rail, moving it above the next yarn winding bobbin and guiding the yarn end to the corresponding bobbin below for continued winding. Even if the previously fully wound bobbin is not removed, it does not affect the normal operation of the yarn winding mechanism. Workers can choose when to handle the yarn winding bobbin without stopping the winding process. This yarn winding guide mechanism improves the continuity of yarn winding production, saves time and manpower, and increases production efficiency. Attached Figure Description

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Example 1

[0031] This embodiment is a yarn winding guiding mechanism; please refer to... Figures 1-3 The device includes a yarn winding mechanism 1, a guiding mechanism 2, and a yarn winding support 4. The guiding mechanism 2 is mounted on the yarn winding support 4, and the yarn winding mechanism 1 is mounted on one side of the yarn winding support 4. Specifically, the yarn winding mechanism 1 includes a yarn winding drum 11 and a motor 12. The motor 12 is connected to the yarn winding drum 11 via a motor shaft. The yarn winding drum 11 is located inside the yarn winding support 4. The guiding mechanism 2 includes a movable guiding support 21 and a guiding wheel 22 mounted on the guiding support. The movable guiding support 21 has I-shaped guiding sliders 23 at both ends. The yarn winding support 4 has a horizontally positioned guiding slide rail 41, which slides in cooperation with the guiding sliders 23 of the movable guiding support 21.

[0032] In this embodiment, the yarn winding guide mechanism 2 achieves switchable guiding positions and seamless transition to a new yarn winding bobbin 11 by setting a guide wheel 22 that can move with the movable guide bracket 21. When the currently winding bobbin 11 reaches the specified winding size during the winding process, the drive mechanism of the movable guide bracket 21 drives the guide slider 23 to slide along the guide rail 41 to the top of the next yarn winding bobbin 11, guiding the end of the yarn to the corresponding lower yarn winding bobbin 11 so that the yarn can continue to be wound. At this time, even if the previously fully wound yarn winding bobbin 11 is not removed temporarily, it does not affect the normal operation of the yarn winding mechanism 1. The operator can choose when to handle the yarn winding bobbin 11 without stopping the yarn winding operation. This yarn winding guide mechanism 2 improves the continuity of yarn winding production, saves time and manpower, and improves production efficiency. In this structure, the guide wheel 22 can rotate around the movable guide bracket 21, and the two can be connected to each other by bearings or other components. The guide wheel 22 also provides a certain tension support to the yarn when guiding the winding of the yarn.

[0033] Preferably, when switching between the two yarn winding drums 11, an automatic yarn cutting mechanism can be provided to cut the yarn connected to the previous yarn winding drum 11, so that the new yarn winding drum 11 can be wound smoothly.

[0034] Example 2

[0035] This embodiment is based on Embodiment 1, please refer to it. Figure 1 , Figure 3 The guide wheel 22 on the movable guide bracket 21 is connected to the two sides of the pressure roller bracket 24, and the pressure roller bracket 24 is provided with a pressure roller group; the pressure roller group includes an upper pressure roller 25 and a lower pressure roller 26, and a gap is provided between the upper pressure roller 25 and the lower pressure roller 26 for yarn to pass through. The upper pressure roller 25 and the lower pressure roller 26 are rotatably connected to the pressure roller bracket 24 respectively.

[0036] In this embodiment, the pressure roller serves as the gap between the guide mechanism 2 and the two yarn winding drums 11. The pressure roller can fix the position of the yarn relative to the position of the guide wheel 22 by the pressure of the upper and lower pressure rollers 26, thereby preventing the yarn from coming off the guide wheel 22 due to movement during the movement of the guide mechanism 2, reducing the need for manual intervention and ensuring the effective operation of the yarn winding process.

[0037] Example 3

[0038] This embodiment is based on Embodiment 1, please refer to it. Figures 3-4A roller groove 42 is provided at the position of the guide rail 41 on the yarn winding bracket 4. A traveling roller 27 is connected to the side of the guide slider 23 opposite to the roller groove 42, and the traveling roller 27 cooperates with the roller groove 42. The traveling roller 27 rolls in the roller groove 42, which drives the guide slider 23 of the movable guide bracket 21 to move along the guide rail 41. The driving force of the traveling roller 27 can be a micro motor or other driving device. The specific structure can be selected and set according to the existing technology and design requirements.

[0039] Example 4

[0040] This embodiment is based on Embodiment 1, please refer to it. Figure 1 , Figure 2 , Figure 5 , Figure 6 A winding support mechanism 3 is provided on the side of the yarn winding bracket 4 opposite to the yarn winding mechanism 1. The winding support mechanism 3 includes a drive cylinder 31 and a support head 32. The drive cylinder 31 is connected to a piston rod 33, and the piston rod 33 is connected to a support rod 34. The support head 32 is fixedly connected to the end of the support rod 34, and the support rod 34 is rotatably connected to the piston rod 33. The support head 32 is used to extend through the piston rod 33 to contact the yarn winding cylinder 11 and support the rotation of the yarn winding cylinder 11.

[0041] The winding support mechanism 3 can improve the stability of the yarn winding process, thereby preventing the yarn drum 11 from shifting or detaching due to the connection stress with the motor shaft and the yarn tension during rotation. Specifically, just before the yarn drum 11 begins winding, the drive cylinder 31 drives the piston rod 33 to extend forward, so that the support head 32 on the support rod 34 is fixedly in contact with the yarn drum 11 and supports it. The support head 32 and the support rod 34 as a whole will rotate together with the yarn drum 11 and rotate relative to the piston rod 33. In this embodiment, the winding support mechanism 3 ensures that both ends of the yarn drum 11 are subjected to force, making the rotation process more stable.

[0042] In a preferred embodiment, multiple inner wall support components are evenly arranged on the side of the support head 32 around the rotation axis of the support rod 34. Each inner wall support component includes an inner wall support seat 321 and an inner wall support block 322 telescopically disposed within the inner wall support seat 321. A pneumatic device is externally connected to the inner wall support seat 321. After the support head 32 penetrates into the hollow position inside the yarn winding drum 11, the inner wall support block 322 extends from the inner wall support seat 321 and contacts and abuts against the inner wall of the yarn winding drum 11, providing circumferential support. This makes the force on the yarn winding drum 11 more even and the support more stable. It should be noted that the driving force provided by the pneumatic device of the inner wall support head 32 should not be too large to prevent damage to the yarn winding drum 11. The side of the inner wall support head 32 that contacts the inner wall of the yarn winding drum 11 can be made of a material that increases friction to prevent relative sliding.

[0043] In a preferred embodiment, a rotary bearing connects the support rod 34 and the piston rod 33, and a cylinder mounting platform 35 is connected to the bottom of the drive cylinder 31. By fixing and supporting the rotation of the support rod 34 and the piston rod 33 to each other through the rotary bearing, the winding support mechanism 3 can provide a more stable supporting force.

[0044] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
