Description

Technical Field

[0001] This utility model relates to the field of vibration damping technology for textile machinery, and specifically to a vibration damping device for textile machinery. Background Technology

[0002] Textile machines, also known as spinning machines, looms, cotton spinning machines, etc., are used to process raw materials such as yarn, silk, and hemp into threads and then weave them into fabric. Examples include spinning wheels, spinning trolleys, spindles, and pedal looms, as well as modern mechanical looms and modern CNC automatic looms. The development of textile processes and equipment throughout history has been designed in response to textile raw materials. Therefore, raw materials play an important role in textile technology. Since most of the vibration in textile machines comes from the power mechanism, the power mechanism vibrates during operation, causing the entire machine to shake and shift. Over time, this can also lead to the loosening of internal screws or other parts. Moreover, the power mechanism generates a lot of noise during operation, and noise pollution can damage the eardrums of employees. Therefore, the use of vibration damping devices is crucial during the operation of textile machines.

[0003] Application No. 202321855041.X discloses a shock-absorbing device for textile machinery, "including a frame, a base plate, a first shock absorber, a buffer, a support, a second shock absorber, a limiting post, a limiting block, and a limiting plate. The base plate is located on the upper side of the bottom of the frame, and casters symmetrically arranged based on the center line of the base plate are provided on the lower side of the base plate. The casters are connected to the frame, and by setting the casters, the chassis can move with the support, so as to continuously buffer the vertical direction when the support causes lateral displacement due to vibration of the textile machinery." The above-mentioned device achieves a shock-absorbing effect on textile machinery through the coordinated cooperation of the shock absorber and the buffer. However, the shock absorber used in this device... Most springs are spring structures. While springs have a certain degree of elasticity and shock absorption, they are prone to fatigue during long-term use, which leads to a decrease in the elastic coefficient and seriously affects the overall shock absorption performance. In addition, the stiffness of the spring structure is fixed, and it cannot be flexibly adjusted according to different vibration conditions and load requirements in the face of complex and changing working conditions. Its adaptability is poor. In low-frequency vibration environments, the shock absorption effect of ordinary springs is significantly poor, and it cannot effectively ensure the stable operation of textile machinery. When encountering rapid changes in vibration, the response speed of the spring structure is slow and cannot provide appropriate shock absorption force for textile machinery in a timely manner. Utility Model Content

[0004] The purpose of this invention is to provide a shock-absorbing device for textile machinery to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing device for textile machinery, comprising a housing, a bearing plate embedded in a groove on the upper surface of the housing, a support column fixedly connected to the lower surface of the bearing plate, a cross plate fixedly connected to the lower surface of the support column, a base plate fixedly connected to the bottom of the inner wall of the housing, and a second conical spring connected to the inner wall of the housing, the free end of the second conical spring being connected to the outer wall of the support column. Unequal pitch springs are connected to the corners of the upper surface of the base plate. When the vibration is small, the smaller pitch portion of the unequal pitch springs is easily compressed, providing a smaller elastic force. When the vibration amplitude increases, the larger pitch portion begins to compress, increasing the overall stiffness of the spring, thereby providing stronger support and shock absorption capabilities. This variable stiffness spring structure can be adapted to the actual conditions of textile machinery. The system automatically adjusts the elastic force according to the vibration, greatly improving the adaptability and damping effect of the shock absorption device. A first conical spring is connected between the two unequal pitch springs and on the upper end face of the base plate. Under small vibrations, the smaller diameter and relatively lower stiffness part of the first conical spring is compressed first, providing a relatively gentle elastic force to buffer the initial vibration. As the vibration amplitude increases, the larger diameter and higher stiffness part begins to deform, generating a greater elastic force to resist stronger vibrations. This gradual stiffness characteristic can effectively avoid the problem of over-buffering or under-buffering that may occur when traditional constant stiffness springs face different vibration intensities. The free ends of the unequal pitch springs and the first conical spring are connected to the horizontal plate. Four limiting blocks are symmetrically fixed to the inner surface of the outer shell, and the four limiting blocks are located at the corners on the outer side of the horizontal plate.

[0006] Preferably, a connecting seat is fixedly connected to the middle position of the upper end face of the bearing plate, and a fastening bolt is threaded onto the connecting seat.

[0007] Specifically, after the support leg of the textile machinery is inserted into the mounting groove of the connecting seat, the fastening bolt is finally tightened to achieve a stable connection between the shock absorption device and the textile machinery, ensuring the stability and reliability of the textile machinery during operation.

[0008] Preferably, the housing is equipped with three airbag-type shock absorption components. Each airbag-type shock absorption component includes two cover plates, two connecting blocks, and an air spring. The two connecting blocks are symmetrically connected to both ends of the air spring, and the two cover plates are connected to the ends of the connecting blocks away from the air spring. A waist ring is connected to the recess of the air spring. One end of one of the cover plates is connected to an air inlet pipe. The air inlet end of the air inlet pipe is connected to an air inlet head, and a cover is fitted over the air inlet head. The air spring is made of nanocomposite material, which has high strength, high elasticity, and wear resistance, and can enhance the strength and durability of the air spring, enabling it to withstand greater pressure and more frequent deformation. An air pressure sensor (not shown in the figure) is installed inside the air spring.

[0009] Preferably, one of the airbag-type shock absorbers is disposed between the horizontal plate and the bottom plate, and the two airbag-type shock absorbers are symmetrically disposed on both sides of the support column.

[0010] Preferably, a ball joint support is connected to the middle position of the outer wall of the support column and the lower end face of the cross plate, and one end of the ball joint support is connected to another cover plate.

[0011] Through the above technical solution:

[0012] In use, the air spring utilizes internal compressed air for shock absorption. Its stiffness and load-bearing capacity can be flexibly adjusted according to the working conditions of textile machinery. When higher stiffness is required, air is added to increase the air pressure; conversely, releasing air to reduce the air pressure decreases the stiffness, thus perfectly adapting to various complex working conditions and expanding the adaptability of textile machinery. At the same time, the air spring also has good vibration isolation performance. In the face of high-frequency vibration, the slight compression and expansion of the internal air can effectively absorb vibration energy, isolating the vibration like a barrier, reducing the impact on the main body of the textile machinery, and effectively ensuring the stable operation of the textile machinery.

[0013] Preferably, a sealing assembly is provided at the connection between the cover and the air inlet head. The sealing assembly includes a rod movably connected to the inner wall of the cover, a sealing block fixedly connected to the outer wall of the rod, a sealing ring meshing with the outer wall of the sealing block, and the sealing ring fixedly connected to the inner wall of the air inlet head.

[0014] Preferably, the sealing assembly further includes a groove formed at the end of the air inlet head, wherein a block is embedded inside the groove, and one end of the block is fixedly connected to the cover.

[0015] Through the above technical solution:

[0016] After the air spring is inflated, the insert rod is first inserted into the air inlet head. Once in place, the cover is placed over the opening of the air inlet head, and the sealing block engages with the inside of the sealing ring. Finally, the cover is rotated, and the insert slides from the opening end of the groove to the other end of the groove. This operation ensures a sealed and secure connection between the cover and the air inlet head. Under the continuous vibration of textile machinery, this effectively prevents air pressure leakage, maintains stable internal air pressure of the air spring, ensures good shock absorption performance, significantly reduces the probability of malfunctions caused by air pressure problems, extends the service life of the air spring, lays the foundation for long-term stable operation of textile machinery, reduces maintenance costs and downtime, and improves overall production efficiency.

[0017] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0018] 1. By setting up an airbag-type shock absorption component, the device has an airbag-type shock absorption function. When in use, the compressed air inside the air spring can be used to achieve the shock absorption function. Its stiffness and load-bearing capacity can be flexibly adjusted according to different working conditions of textile machinery. This feature allows the air spring to perfectly meet the requirements of textile machinery under various complex working conditions, greatly expanding the working adaptability of textile machinery. At the same time, the air spring also has good vibration isolation performance. When high-frequency vibration is transmitted to the air spring, the small compression and expansion process of the air inside the spring can effectively absorb the vibration energy and isolate the vibration on one side of the air spring, greatly reducing the impact on the main body of the textile machinery and providing a strong guarantee for the stable operation of the textile machinery.

[0019] 2. By incorporating a sealing component, the sealing and secure connection between the cover and the air inlet head are ensured during use. This prevents air pressure leakage due to loose connections during continuous operation and vibration of textile machinery, guaranteeing stable internal air pressure and maintaining excellent shock absorption performance. Simultaneously, it significantly reduces the probability of malfunctions caused by air pressure issues, substantially extending the service life of the air spring. This lays a solid foundation for the long-term stable operation of textile machinery, reduces maintenance costs and downtime, and improves overall production efficiency. Attached Figure Description

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] This utility model provides, for example Figures 1-3 A shock-absorbing device for textile machinery, as shown, includes:

[0032] The outer casing 1 has a groove on its upper surface in which a support plate 2 is embedded. A support column 3 is fixedly connected to the lower surface of the support plate 2, and a horizontal plate 4 is fixedly connected to the lower surface of the support column 3. A base plate 5 is fixedly connected to the bottom of the inner wall of the outer casing 1, and a second conical spring 9 is connected to the inner wall of the outer casing 1. The free end of the second conical spring 9 is connected to the outer wall of the support column 3. Unequal pitch springs 7 are connected to the corners of the upper surface of the base plate 5. When the vibration is small, the smaller pitch portion of the unequal pitch springs 7 is easily compressed, providing a smaller elastic force. When the vibration amplitude increases, the larger pitch portion begins to compress, increasing the overall stiffness of the spring, thereby providing stronger support and shock absorption capabilities. This variable stiffness spring structure can automatically adjust the elastic force according to the actual vibration of the textile machinery, greatly improving the shock absorption capacity. To improve the adaptability and damping effect of the vibration device, a first conical spring 8 is connected between the two unequal pitch springs 7 and on the upper end of the base plate 5. Under small vibrations, the smaller diameter and relatively lower stiffness part of the first conical spring 8 is compressed first, providing a gentler elastic force to buffer the initial vibration. As the vibration amplitude increases, the larger diameter and higher stiffness part begins to deform, generating a greater elastic force to resist stronger vibrations. This gradual stiffness characteristic can effectively avoid the problem of over-buffering or under-buffering that may occur when traditional constant stiffness springs face different vibration intensities. The free ends of the unequal pitch springs 7 and the first conical spring 8 are both connected to the horizontal plate 4. Four limiting blocks 15 are symmetrically fixedly connected to the inner surface of the outer shell 1. The four limiting blocks 15 are located at the corners on the outer side of the horizontal plate 4.

[0033] Further, see Figure 2 and Figure 3 As shown, a connecting seat 16 is fixedly connected to the middle position of the upper end face of the bearing plate 2, and a fastening bolt is threaded onto the connecting seat 16.

[0034] Specifically, after the support leg of the textile machinery is inserted into the mounting groove of the connecting seat 16, the fastening bolt is finally tightened to achieve a stable connection between the shock absorption device and the textile machinery, ensuring the stability and reliability of the textile machinery during operation.

[0035] This utility model provides, for example Figures 2-4The illustrated shock-absorbing device for textile machinery includes an airbag-type shock-absorbing assembly 6 inside the outer casing 1. There are three airbag-type shock-absorbing assemblies 6, each comprising two cover plates 61, two connecting blocks 62, and an air spring 63. The two connecting blocks 62 are symmetrically connected to both ends of the air spring 63. The two cover plates 61 are connected to the ends of the connecting blocks 62 furthest from the air spring 63. A waist ring 64 is connected to the recessed part of the air spring 63. One end of one cover plate 61 is connected to an air inlet pipe 66, and the air inlet end of the air inlet pipe 66 is connected to an air inlet head 67. A cover 68 is fitted over the air inlet head 67. The air spring 63 is made of nanocomposite material, which has high strength, high elasticity, and wear resistance, enhancing the strength and durability of the air spring 63, enabling it to withstand greater pressure and more frequent deformation. An air pressure sensor (not shown in the figure) is also installed inside the air spring 63.

[0036] One of the airbag-type shock absorber components 6 is located between the horizontal plate 4 and the bottom plate 5, and the two airbag-type shock absorber components 6 are symmetrically located on both sides of the support column 3.

[0037] A ball joint support 65 is connected to the outer wall of the support column 3 and the middle position of the lower end face of the cross plate 4, and one end of the ball joint support 65 is connected to another cover plate 61.

[0038] Through the above technical solution:

[0039] When in use, the air spring 63 uses internal compressed air for shock absorption. Its stiffness and load-bearing capacity can be flexibly adjusted according to the working conditions of textile machinery. When higher stiffness is required, air can be added to increase the air pressure. Conversely, releasing air to reduce the air pressure can reduce the stiffness, thus perfectly adapting to various complex working conditions and expanding the working adaptability of textile machinery. At the same time, the air spring 63 also has good vibration isolation performance. In the face of high-frequency vibration, the slight compression and expansion of the internal air can effectively absorb vibration energy, isolating the vibration like a barrier, reducing the impact on the main body of textile machinery, and effectively ensuring the stable operation of textile machinery.

[0040] This utility model provides, for example Figures 5-7 The vibration damping device for textile machinery shown has a sealing assembly at the connection between the cover 68 and the air inlet head 67. The sealing assembly includes an insert rod 10 movably connected to the inner wall of the cover 68, a sealing block 11 fixedly connected to the outer wall of the insert rod 10, a sealing ring 12 meshing with the outer wall of the sealing block 11, and the sealing ring 12 fixedly connected to the inner wall of the air inlet head 67.

[0041] The sealing assembly also includes a groove 13 at the end of the air inlet head 67, and a block 14 is embedded inside the groove 13. One end of the block 14 is fixedly connected to the cover 68.

[0042] Through the above technical solution:

[0043] After the air spring 63 is inflated, the insert rod 10 is first inserted into the air inlet head 67. Once in place, the cover 68 is placed over the opening of the air inlet head 67, and the sealing block 11 engages with the inside of the sealing ring 12. Finally, the cover 68 is rotated, and the insert 14 slides from the opening end of the groove 13 to the other end of the groove 13. This operation ensures a tight seal and secure connection between the cover 68 and the air inlet head 67. Under the continuous vibration of textile machinery, this effectively prevents air pressure leakage, maintains stable internal air pressure of the air spring 63, ensures good shock absorption performance, significantly reduces the probability of failure caused by air pressure problems, extends the service life of the air spring 63, lays the foundation for long-term stable operation of textile machinery, reduces maintenance costs and downtime, and improves overall production efficiency.
