Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to a novel vibration-damping yarn spindle. Background Technology

[0002] The spindle is one of the main components of the spinning machine for twisting and winding. It is an assembly with a slender rotating shaft supported at two points. Spindles inevitably vibrate and wear during rotation. Severe vibration can cause bobbins to jump, resulting in yarn breakage or poor yarn formation, and accelerating the wear of machine parts, which is especially noticeable at high speeds.

[0003] When spinning spindles rotate at high speeds, they exhibit longitudinal and lateral vibrations. Longitudinal vibration refers to the up-and-down movement of the spindle and bobbin, while lateral vibration is commonly known as spindle head shaking. Traditional vibration reduction measures for spindles typically involve dual elastic elements, namely, using an elastic tube and a spring installed at the lower bearing of the spindle rod. However, the contact between the bottom of the spindle rod and the bottom of the spindle foot is usually a fixed surface contact or point contact, resulting in poor overall vibration reduction, especially as this type of vibration reduction measure is prone to generating significant lateral vibration.

[0004] To address this, a novel vibration-damping fine yarn spindle is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a novel vibration-damping fine yarn spindle in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A novel vibration-damping spindle includes a spindle foot, a flexible rubber ring fixedly installed on the inner wall of the spindle foot, and a bearing fixedly installed on the inner ring of the flexible rubber ring. A spindle rod is fixedly inserted into the inner ring of the bearing. A transverse vibration damping mechanism is provided on the inner wall of the spindle foot and the surface of the spindle rod located inside the spindle foot. A longitudinal vibration damping mechanism is provided at the bottom of the spindle foot and the bottom end of the spindle rod. The transverse and longitudinal vibration damping mechanisms are used to reduce longitudinal and transverse vibrations during the rotational movement of the spindle rod.

[0008] Furthermore, the spindle rod is mounted in a rotatable manner via bearings and spindle feet, and a spindle disc is fixedly sleeved on the surface of the spindle rod located outside the spindle feet.

[0009] Furthermore, the transverse damping mechanism includes a housing fixedly inserted into the inner wall of the spindle foot, and a rotating ring is rotatably mounted on the inner wall of the housing. Multiple sets of first damping springs are fixedly connected between the surface of the spindle rod and the rotating ring.

[0010] Furthermore, the longitudinal vibration damping mechanism includes a connecting shaft inserted into the bottom end of the spindle rod, and the spindle rod and the connecting shaft are internally threaded with a first bolt. A movable connecting plate is rotatably installed at the bottom end of the connecting shaft, and a fixed connecting plate is fixedly installed on the inner bottom of the spindle foot by a second bolt. A second vibration damping spring is fixedly installed between the movable connecting plate and the fixed connecting plate.

[0011] Furthermore, the diameter of the movable connecting plate is equal to the inner diameter of the spindle foot, and the movable connecting plate is vertically slidable inside the spindle foot.

[0012] Furthermore, the inner wall of the housing is provided with a limiting protrusion ring, and the rotating ring is rotatably mounted on the inner wall of the housing and located between the limiting protrusion rings.

[0013] The beneficial effects of this utility model are as follows:

[0014] The flexible rubber ring installed on the inner side of the spindle foot creates a buffer gap between the bearing and the spindle foot, reducing the impact of rotation. At the same time, the transverse and longitudinal vibration damping mechanisms set on the inner wall of the spindle foot and the bottom of the spindle rod respectively buffer and absorb the transverse and longitudinal vibrations of the spindle rod, effectively suppressing the transmission of vibration to the yarn and machine parts. When the spindle rod rotates at high speed, the bearing first connects the spindle rod and the spindle foot. The buffering characteristics of the flexible rubber ring create a gap between the bearing and the spindle foot. Finally, through the synergistic action of the transverse and longitudinal vibration damping mechanisms, the longitudinal and transverse vibrations of the spindle rod are effectively absorbed, reducing yarn breakage or poor forming, and extending the service life of the machine.

[0026] like Figures 1 to 6As shown, a novel vibration-damping spinning spindle includes a spindle foot 1. A flexible rubber ring 2 is fixedly installed on the inner wall of the spindle foot 1, and a bearing 3 is fixedly installed on the inner ring of the flexible rubber ring 2. A spindle rod 4 is fixedly inserted into the inner ring of the bearing 3. A transverse vibration damping mechanism 6 is provided on the inner wall of the spindle foot 1 and the surface of the spindle rod 4 located inside the spindle foot 1. A longitudinal vibration damping mechanism 7 is provided on the bottom of the spindle foot 1 and the bottom end of the spindle rod 4. The transverse vibration damping mechanism 6 and the longitudinal vibration damping mechanism 7 are used to reduce longitudinal and transverse vibrations when the spindle rod 4 rotates. More specifically, the bearing 3 enables the spindle rod 4 and the spindle foot 1 to be rotated. The flexible rubber ring 2 on the inner wall of the spindle foot 1 enables a buffer gap to exist between the bearing 3 and the spindle foot 1. The transverse vibration damping mechanism 6 enables the transverse vibration of the spindle rod 4 to be buffered and absorbed during its rotation. The longitudinal vibration damping mechanism 7 enables the longitudinal vibration of the spindle rod 4 to be buffered and absorbed during its rotation.

[0027] The spindle 4 is mounted in a rotatable manner with respect to the spindle foot 1 via the bearing 3, and a spindle disc 5 is fixedly sleeved on the surface of the spindle 4 outside the spindle foot 1. More specifically, the spindle disc 5 is fixedly sleeved on the surface of the spindle 4, and the relative rotation between the spindle 4 and the spindle foot 1 enables the high-speed rotational motion of the spindle 4 and the spindle disc 5.

[0028] The lateral vibration damping mechanism 6 includes a housing 601 fixedly inserted into the inner wall of the spindle foot 1, and a rotating ring 602 is rotatably mounted on the inner wall of the housing 601. Multiple sets of first damping springs 603 are fixedly connected between the surface of the spindle rod 4 and the rotating ring 602. More specifically, the spindle rod 4 drives the first damping springs 603 and the rotating ring 602 to rotate relative to each other on the inner wall of the lateral vibration damping mechanism 6. The first damping springs 603 create an elastic connection between the spindle rod 4 and the rotating ring 602, and the lateral vibration force during the rotation of the spindle rod 4 is absorbed by the elastic force of the first damping springs 603.

[0029] The longitudinal vibration damping mechanism 7 includes a connecting shaft 701 inserted into the bottom end of the spindle 4, and a first bolt 702 is threadedly inserted into the spindle 4 and the connecting shaft 701. A movable connecting plate 703 is rotatably mounted on the bottom end of the connecting shaft 701. A fixed connecting plate 705 is fixedly mounted on the inner bottom of the spindle foot 1 by a second bolt 706, and a second vibration damping spring 704 is fixedly mounted between the movable connecting plate 703 and the fixed connecting plate 705. More specifically, the first bolt 702 is threaded into the spindle rod 4 and its internal connecting shaft 701, thereby fixing the bottom end of the connecting shaft 701 and the spindle rod 4. Since the connecting shaft 701 and the movable connecting plate 703 are rotatably installed, the bottom end of the spindle rod 4 and the movable connecting plate 703 rotate relative to each other as the spindle rod 4 rotates. Due to the vibration force, the movable connecting plate 703 moves within the spindle foot 1, thereby compressing the second damping spring 704. The second damping spring 704 absorbs the longitudinal vibration force during the rotation of the spindle rod 4.

[0030] The diameter of the movable connecting plate 703 is equal to the inner diameter of the spindle foot 1, and the movable connecting plate 703 is vertically slidable inside the spindle foot 1. More specifically, the inner wall of the spindle foot 1 provides limiting and guiding for the vertical movement of the movable connecting plate 703.

[0031] The inner wall of the housing 601 is provided with limiting protrusions, and the rotating ring 602 is rotatably mounted on the inner wall of the housing 601 and located between the limiting protrusions. More specifically, the limiting protrusions on the inner wall of the housing 601 are used to limit the installation of the rotating ring 602.

[0032] In summary: the bearing 3 enables the spindle 4 and spindle foot 1 to rotate, the flexible rubber ring 2 on the inner wall of spindle foot 1 enables a buffer gap between the bearing 3 and spindle foot 1, the lateral vibration damping mechanism 6 enables the lateral vibration of the spindle 4 to be buffered and absorbed during its rotation, and the longitudinal vibration damping mechanism 7 enables the longitudinal vibration of the spindle 4 to be buffered and absorbed during its rotation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
