Description

Technical Field

[0001] This utility model relates to the field of sensor base technology, and in particular to a shock-absorbing mounting base for a high-precision tension sensor for a texturing machine. Background Technology

[0002] During operation, the vibrations of components such as the rollers, false twister, and heating box in a texturing machine are directly transmitted to the tension sensor, leading to measurement errors. According to search results, the vibration frequency range of a texturing machine is 0~50Hz, with optimal vibration damping at 30Hz and an amplitude range of 0~1.5mm. High-precision tension sensors (such as surface acoustic wave (SAW) sensors need to achieve a resolution of 0.001N and an accuracy of 1.6205%. Prolonged vibration can cause internal components to loosen or be damaged; therefore, tension sensors are typically mounted on a vibration-damping base.

[0003] In existing technologies, the structure of the shock-absorbing base is relatively simple, and it can often only alleviate the oscillation in the vertical direction. This means that the oscillation in the horizontal direction will still affect the detection of the tension sensor, making it difficult to meet people's usage needs. Utility Model Content

[0004] The purpose of this invention is to provide a shock-absorbing mounting base for a high-precision tension sensor in a texturing machine, in order to solve the problem of the influence of horizontal oscillations on the tension sensor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vibration-damping mounting base for a high-precision tension sensor in a texturing machine includes a base plate and a sensor body located on top of it. The base plate and the sensor body are connected by a connecting assembly, which includes a first plate, a second plate, and a third plate. The base plate and the first plate are connected by a first vibration-damping unit, the first plate and the second plate are connected by a second vibration-damping unit, and the second plate and the third plate are connected by a third vibration-damping unit. The sensor body is mounted on the third plate.

[0007] As a further description of the above technical solution: the first damping unit includes a first spring fixedly installed between the fixed plate and the base plate, and the fixed plate is fixedly installed on the lower end face of the first plate.

[0008] As a further description of the above technical solution: a damper is fixedly installed between the fixed plate and the base plate, and the damper is located inside the first spring.

[0009] As a further description of the above technical solution: the second damping unit includes a first groove formed on the first plate and a second spring fixedly installed between the first fixed block and the first slider. The first fixed block is fixedly installed in the first groove, the first slider is slidably installed in the first groove, and the first slider is fixedly connected to the lower end face of the second plate.

[0010] As a further description of the above technical solution: the third damping unit includes a second slide groove formed on the second plate, and a third spring fixedly installed between the second fixed block and the second slider. The second fixed block is fixedly installed in the second slide groove, the second slider is slidably installed in the second slide groove, and the second slider is fixedly connected to the lower end face of the third plate.

[0011] As a further description of the above technical solution: a first rubber pad is fixedly installed on the upper surface of the base plate, and a second rubber pad is fixedly installed at the ends of both the first and second slide grooves.

[0012] As a further description of the above technical solution: the base plate is provided with mounting holes, and the third plate is provided with mounting grooves.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] The first damping unit absorbs the energy of the sensor body's vertical vibration, and the second and third damping units absorb the energy of the sensor body's vertical vibration. The entire device can absorb vibration energy from multiple directions, ensuring the positional stability of the sensor body during operation as much as possible and meeting the usage requirements.

[0015] When the vibration is large, the first plate may hit the bottom plate. The first rubber pad can buffer this impact. Similarly, the second rubber pad can buffer the impact of the first and second sliders on the ends of the first and second slide grooves. This not only protects the various parts inside the device, but also reduces the noise generated during impact, making it highly practical. Attached Figure Description

[0023] 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.

[0024] Example: This example provides a shock-absorbing mounting base for a high-precision tension sensor in a texturing machine. See [link / reference]. Figure 1 - Figure 5 Specifically, it includes a base plate 1 and a sensor body 11 located on top of it. The base plate 1 and the sensor body 11 are connected by a connecting assembly, which includes a first plate 12, a second plate 13 and a third plate 14. The base plate 1 and the first plate 12 are connected by a first damping unit, the first plate 12 and the second plate 13 are connected by a second damping unit, and the second plate 13 and the third plate 14 are connected by a third damping unit. The sensor body 11 is mounted on the third plate 14.

[0025] The first damping unit absorbs the energy of the sensor body 11 vibrating up and down. The second and third damping units absorb the energy of the sensor body 11 vibrating up and down. The entire device can absorb the energy of vibration from multiple directions, ensuring the positional stability of the sensor body 11 as much as possible during operation.

[0026] The first damping unit includes a first spring 21 fixedly installed between the fixed plate 2 and the base plate 1. The fixed plate 2 is fixedly installed on the lower end face of the first plate 12. A damper 3 is fixedly installed between the fixed plate 2 and the base plate 1. The damper 3 is located inside the first spring 21.

[0027] When the sensor body 11 vibrates up and down, the sensor body 11 drives the first plate 12 to move up and down through the connecting assembly. The first plate 12 stretches and compresses the first spring 21 through the fixed plate 2, absorbing the energy of the up and down vibration. Since the sensor body 11 is mainly affected by the up and down vibration, the damper 3 irreversibly converts the kinetic energy into heat energy and dissipates it through internal friction or the throttling resistance of the fluid, reducing the number of times the first spring 21 is repeatedly deformed, so that the sensor body 11 is as stable as possible.

[0028] The second damping unit includes a first groove 4 formed on the first plate 12, and a second spring 43 fixedly installed between the first fixed block 41 and the first slider 42. The first fixed block 41 is fixedly installed in the first groove 4, the first slider 42 is slidably installed in the first groove 4, and the first slider 42 is fixedly connected to the lower end face of the second plate 13.

[0029] When the sensor body 11 vibrates along the first slide groove 4, the second plate 13 forces the second spring 43 to deform through the first slider 42, and the second spring 43 absorbs the energy of vibration in this direction through its own deformation.

[0030] The third damping unit includes a second slide groove 5 opened on the second plate 13, and a third spring 53 fixedly installed between the second fixed block 51 and the second slider 52. The second fixed block 51 is fixedly installed in the second slide groove 5, the second slider 52 is slidably installed in the second slide groove 5, and the second slider 52 is fixedly connected to the lower end face of the third plate 14.

[0031] When the sensor body 11 vibrates along the direction of the second slide groove 5, the third plate 14 forces the third spring 53 to deform through the second slider 52. The third spring 53 absorbs the energy of vibration in this direction through its own deformation. It should be noted that: during the deformation process, one of the two second springs 43 and the third spring 53 in the same first slide groove 4 and the second slide groove 5 is always in a stretched state, while the other is in a compressed state. The elastic forces of the two second springs 43 and the third spring 53 are superimposed to ensure that they can resist strong vibrations and that the position of the sensor body 11 will not change significantly, thus ensuring the stability of the sensor body 11.

[0032] A first rubber pad 6 is fixedly installed on the upper surface of the base plate 1, and a second rubber pad 61 is fixedly installed at the ends of the first slide groove 4 and the second slide groove 5.

[0033] When the vibration is large, the first plate 12 may hit the bottom plate 1. The first rubber pad 6 can buffer this impact. Similarly, the second rubber pad 61 can buffer the impact of the first slider 42 and the second slider 52 on the ends of the first slide groove 4 and the second slide groove 5. This not only protects the various parts in the device, but also reduces the noise generated by the impact, making it highly practical.

[0034] The base plate 1 has mounting holes 7 and the third plate 14 has mounting grooves 71.

[0035] Mounting hole 7 is used to fix base plate 1 in the area to be installed, and mounting groove 71 is used to install sensor body 11 on third plate 14.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
