Description

Technical Field

[0001] This utility model relates to the field of textile machinery spindle technology, specifically a textile machinery spindle with a damping structure. Background Technology

[0002] The spindle in textile machinery is a key component in spinning equipment used to support and drive the yarn bobbin or winding body to rotate at high speed. It typically consists of a mounting base, spindle shaft, and support structure. During operation, the spindle has the dual function of evenly winding the yarn onto the yarn bobbin and maintaining stable rotational accuracy and good dynamic balance to ensure yarn formation quality and spinning efficiency.

[0003] Existing textile machinery spindles are susceptible to axial and non-axial vibrations during high-speed operation. If only spring structures are used for buffering, there are often problems such as insufficient damping efficiency and limited buffering performance, which can easily lead to reduced spindle operation stability, noise and mechanical wear, thereby shortening the service life of the spindle.

[0004] Therefore, it is necessary to design a textile machinery spindle with a damping structure to solve the above problems. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figure 1-3 This utility model provides a textile machinery spindle with a damping structure, including a mounting base 1. A spindle end 2 is slidably inserted into the top of the mounting base 1, and a damping block 6 is fixedly connected to the bottom of the mounting base 1. An oil groove 20 is formed inside the mounting base 1, and a cylindrical groove 18 is formed at the bottom of the oil groove 20. A positioning post 10 is fixedly connected to the bottom of the damping block 6, and the bottom end of the positioning post 10 is slidably inserted into the interior of the cylindrical groove 18. A spring 11 is sleeved on the outer surface of the positioning post 10. Two symmetrical plug-in blocks 15 are fixedly attached to the outer surface of the damping block 6, and two symmetrical plug-in slots 17 are opened on the inner wall of the oil tank 20. The two plug-in blocks 15 are slidably inserted into the two plug-in slots 17 respectively. Multiple liquid inlet holes are opened on the outer surface of the damping block 6. Multiple second sealing rings 12 are fixedly attached to the inner wall of the cylindrical groove 18. Multiple first sealing rings 7 are fixedly attached to the inner wall of the top end of the mounting base 1. An oil inlet 8 and a sludge outlet 9 are fixedly inserted into the top end of the mounting base 1. The top and bottom of the oil tank 20 are respectively provided with an upper annular groove 13 and a lower annular groove 14. When the device is in use, the shallow oil tank 20 limits the sliding range of the damping block 6 inside the oil tank 20. Silicone oil is filled into the oil tank 20 through the oil inlet 8, while the impurity outlet 9 facilitates the discharge of gas and the removal of water and impurities during cleaning. When the spindle end 2 rotates, the elasticity of the spring 11 dampens and buffers the axial vibration of the spindle end 2. However, due to the spring... The buffering efficiency of 11 is relatively low. Therefore, by the slight sliding of the damping block 6 in the silicone oil, the damping buffer generated by multiple liquid inlet holes and oil pressure is used in conjunction with the spring 11 to achieve multi-layer buffering efficiency. At the same time, the setting of the upper ring groove 13 and the lower ring groove 14 can also improve the backflow effect of the oil circuit, thereby improving the overall damping effect of the device and extending the service life of the device. In order to improve the stability of the axial sliding of the damping block 6 and the spindle end 2, the sliding limit is achieved by the two plug-in blocks 15 and the positioning column 10.

[0021] To better fill the silicone oil required for damping operation and facilitate the periodic cleaning of impurities inside the oil tank 20, the oil inlet 8 and the impurity outlet 9 are located on both sides of the spindle end 2, and the top of the oil inlet 8 and the impurity outlet 9 are equipped with pistons 4, and the bottom of the oil inlet 8 and the impurity outlet 9 are connected to the interior of the oil tank 20.

[0022] In order to utilize the elasticity of the spring 11 to provide a layer of damping and buffering, the spring 11 is sleeved on the outside of the positioning post 10, and the top and bottom ends of the spring 11 are respectively fixed to the bottom of the damping block 6 and the bottom of the oil tank 20. A gap is formed between the outer surface of the damping block 6 and the inner wall of the oil tank 20.

[0023] In order to improve the overall sealing of the device and prevent silicone oil from overflowing when the spindle end 2 and the positioning post 10 slide, the outer surface of the bottom end of the spindle end 2 is in contact with the inner wall of the multiple first sealing rings 7, and the bottom end of the positioning post 10 is in contact with the inner wall of the multiple second sealing rings 12.

[0024] In order to buffer non-axial vibration, one end of each of the two insertion blocks 15 is fixed with a rubber block 16, and the two rubber blocks 16 are respectively attached to one side of the inner cavity of the two insertion slots 17, and the two sides of the two rubber blocks 16 and the two insertion blocks 15 are respectively attached to the other two sides of the inner cavity of the two insertion slots 17.

[0025] In order to improve the overall winding efficiency of the device and facilitate the stable installation of the device, the spindle end 2 is provided with multiple winding grooves 3 on the outer surface of the top of the mounting base 1, and multiple equally spaced fixed iron rings 5 ​​are fixed to the outer surface of the mounting base 1.

However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
