Description

Technical Field

[0001] This application relates to the field of twisting machine technology, specifically a yarn bobbin for a twisting machine. Background Technology

[0002] As an important piece of equipment in the textile industry, the twisting machine is used to process yarn or plied yarn products into linear products. It is widely used in weaving and knitting. With the continuous development of textile technology, the production efficiency and quality requirements of twisting machines have gradually increased. As one of the key components of the twisting machine, the stability of the yarn bobbin support structure directly affects the operation of the twisting machine.

[0003] Currently, the yarn bobbin support structure of twisting machines mostly adopts a direct embedding method. This method can meet the requirements in low vibration environments, but in high vibration environments, it is easy to cause the yarn bobbin to shake or even fall off, affecting production efficiency and product quality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a yarn bobbin for a twisting machine, which has the advantages of improving the installation stability of the yarn bobbin and effectively preventing the yarn bobbin from shaking or falling off in high vibration environments. It solves the problem that using a direct embedding method to support and position the yarn bobbin can easily lead to shaking or even falling off in high vibration environments, affecting production efficiency and product quality.

[0005] To achieve the above objectives, this application provides the following technical solution: a yarn bobbin for a twisting machine, comprising a base, with two elastic clamping members symmetrically arranged on the upper surface of the base. Each elastic clamping member includes a connecting part, two symmetrically arranged arc-shaped support parts, and two bending parts. The connecting part is fixedly connected to the arc-shaped support parts through the bending parts. A first shock-absorbing pad is fixedly connected to the inner wall of each arc-shaped support part. A yarn bobbin body is provided on the upper surface of the base. The two elastic clamping members are in contact with the outer circumferential surface of the yarn bobbin body through the first shock-absorbing pads. A lead screw is rotatably connected inside the base. Two threaded tubes are threadedly connected to the outer circumferential surface of the lead screw. A connecting plate is fixedly connected to the outer circumferential surface of each threaded tube. A back plate is fixedly connected to the upper surface of each connecting plate. The outer surface of the back plate is fixedly connected to the outer surface of the connecting part. A worm gear is rotatably connected inside the base. A worm wheel is fixedly sleeved on the outer circumferential surface of the lead screw, and the worm wheel meshes with the worm gear.

[0006] The above solution addresses the issue that directly embedding the yarn bobbin for support and positioning can easily cause it to sway or even fall off in high-vibration environments, affecting production efficiency and product quality. By incorporating an elastic clamping component consisting of a connecting part, an arc-shaped support part, and a bending part, the elastic deformation characteristics of the clamping component can absorb vibration energy during operation, achieving a certain shock absorption effect. This improves the installation stability of the yarn bobbin body and effectively prevents it from swaying or falling off in high-vibration environments. Furthermore, by setting a first shock-absorbing pad on the inner wall of the arc-shaped support part, the shock absorption effect on the yarn bobbin body is further optimized.

[0007] Furthermore, the elastic clamping member is made of spring steel, and its outer surface is coated with an anti-rust coating.

[0008] Through the above solution, spring steel has good elasticity and fatigue resistance, which enables the elastic clamping component to maintain stable clamping of the yarn bobbin body for a long time. Even under frequent use and vibration environments, it can maintain its shape and performance. The anti-rust coating on the outer surface of the elastic clamping component can effectively prevent it from being affected by environmental factors such as moisture and corrosive gases, thus extending its service life.

[0009] Furthermore, two first limiting rings are fixedly sleeved on the outer circumferential surface of the lead screw, and the side of the first limiting rings near the base contacts the outer surface of the base respectively.

[0010] The above method restricts the lead screw, preventing it from sliding off the base and improving the stability of the lead screw's movement.

[0011] Furthermore, the base has two limiting holes inside, and the outer surface of the connecting plate is slidably connected to the base through the limiting holes.

[0012] The above scheme restricts the threaded tube, preventing it from rotating with the lead screw, thus ensuring that the connecting plate always drives the back plate and the elastic clamping component to move laterally, thereby improving the stability of the elastic clamping component's movement.

[0013] Furthermore, the lead screw is centrally located inside the base, and the lead screw is a bidirectional threaded rod.

[0014] The above scheme enables the two threaded tubes to move simultaneously in opposite directions, thereby causing the two elastic clamping parts to open and close simultaneously, completing the positioning operation of the yarn bobbin body.

[0015] Furthermore, two second limiting rings are fixedly sleeved on the outer circumferential surface of the worm gear, and the side of the second limiting rings near the base contacts the outer surface of the base respectively.

[0016] The above solution restricts the worm gear, preventing it from sliding laterally and causing misalignment between the worm gear and the worm wheel, which could damage the device.

[0017] Furthermore, a mounting plate is fixedly connected to the bottom of the base, and the mounting plate has four mounting holes inside.

[0018] With the above solution, the mounting plate can provide stable support for the base, and bolts can be used to fix the mounting plate to the body of the twisting machine through the mounting holes on the mounting plate.

[0019] Furthermore, a second shock-absorbing pad is fixedly connected to the bottom surface of the mounting plate, and the second shock-absorbing pad has through holes corresponding to the mounting holes inside.

[0020] Through the above solution, the second damping pad can effectively absorb the vibration energy during the operation of the twisting machine, further reducing the vibration and noise generated by the entire mechanism during operation, and improving the stability and comfort of the equipment.

[0021] Furthermore, both the first and second shock-absorbing pads are made of rubber.

[0022] Through the above solution, the rubber material has good elasticity and shock absorption performance, which can effectively absorb and disperse vibration energy, reduce equipment vibration and noise. At the same time, the rubber material also has good wear resistance and corrosion resistance, which can extend the service life of the shock absorption pad.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This twisting machine yarn bobbin, by incorporating an elastic clamping component consisting of a connecting part, an arc-shaped support part, and a bending part, can absorb vibration energy during operation through the elastic deformation characteristics of the clamping component, achieving a certain shock absorption effect. This improves the installation stability of the yarn bobbin body and effectively prevents the yarn bobbin body from shaking or falling off in high-vibration environments. By setting a first shock-absorbing pad on the inner wall of the arc-shaped support part, the shock absorption effect on the yarn bobbin body is further optimized. The movement and clamping action of the elastic clamping component is realized through the linkage of the worm, worm wheel, and lead screw, which not only facilitates operation but also further improves the positioning stability of the yarn bobbin body by utilizing the self-locking characteristics of the worm and worm wheel.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 2 and Figure 5 This embodiment of a twisting machine yarn bobbin includes a base 1. Two elastic clamping members 2 are symmetrically arranged on the upper surface of the base 1. Each elastic clamping member 2 includes a connecting part 201, two symmetrically arranged arc-shaped support parts 202, and two bending parts 203. The connecting part 201 is fixedly connected to the arc-shaped support parts 202 via the bending parts 203. A first shock-absorbing pad 10 is fixedly connected to the inner wall of each arc-shaped support part 202. The upper surface of the base 1 is provided with a yarn bobbin body 3. The two elastic clamping members 2 are respectively connected to... The first shock-absorbing pad 10 contacts the outer circumferential surface of the yarn bobbin body 3. The base 1 is rotatably connected to a lead screw 4. The outer circumferential surface of the lead screw 4 is threadedly connected to two threaded tubes 5. The outer circumferential surface of each threaded tube 5 is fixedly connected to a connecting plate 6. The upper surface of each connecting plate 6 is fixedly connected to a back plate 7. The outer surface of the back plate 7 is fixedly connected to the outer surface of the connecting part 201. The base 1 is rotatably connected to a worm gear 8. The outer circumferential surface of the lead screw 4 is fixedly sleeved with a worm wheel 9. The worm wheel 9 meshes with the worm gear 8.

[0034] Please see Figure 1 , Figure 3 and Figure 5The elastic clamping component 2 is made of spring steel, and its outer surface is coated with an anti-rust coating. Spring steel has good elasticity and fatigue resistance, which enables the elastic clamping component 2 to maintain stable clamping of the yarn bobbin body 3 for a long time. Even in frequent use and vibration environments, it can maintain its shape and performance. The anti-rust coating on the outer surface of the elastic clamping component 2 can effectively prevent it from being affected by environmental factors such as moisture and corrosive gases, thus extending its service life.

[0035] Please see Figure 1 , Figure 2 and Figure 3 Two first limiting rings 11 are fixedly sleeved on the outer circumferential surface of the lead screw 4. The side of the first limiting ring 11 closest to the base 1 contacts the outer surface of the base 1 to restrict the lead screw 4, prevent the lead screw 4 from sliding off the base 1, and improve the stability of the movement of the lead screw 4.

[0036] Please see Figure 1 , Figure 2 and Figure 3 The base 1 has two limiting holes 12 inside. The outer surface of the connecting plate 6 is slidably connected to the base 1 through the limiting holes 12 to restrict the threaded tube 5 and prevent the threaded tube 5 from rotating with the screw 4. This causes the connecting plate 6 to always drive the back plate 7 and the elastic clamping member 2 to move laterally, thereby improving the stability of the movement of the elastic clamping member 2.

[0037] Please see Figure 2 and Figure 4 The lead screw 4 is centrally located inside the base 1. The lead screw 4 is a bidirectional threaded rod, which enables the two threaded tubes 5 to move simultaneously in opposite directions, thereby causing the two elastic clamping parts 2 to open and close simultaneously, completing the positioning operation of the yarn bobbin body 3.

[0038] Please see Figure 1 , Figure 2 and Figure 3 Two second limiting rings 13 are fixedly sleeved on the outer circumferential surface of the worm 8. The side of the second limiting ring 13 closest to the base 1 contacts the outer surface of the base 1 to restrict the worm 8 and prevent the worm 8 from sliding laterally, which would cause the worm 8 and the worm wheel 9 to misalign and damage the device.

[0039] Please see Figure 1 , Figure 2 and Figure 3 The bottom of the base 1 is fixedly connected to the mounting plate 14. The mounting plate 14 has four mounting holes 15 inside. The mounting plate 14 can provide stable support for the base 1. At the same time, the mounting plate 14 can be fixedly connected to the body of the twisting machine by bolts through the mounting holes 15 on the mounting plate 14.

[0040] Please see Figure 1 , Figure 2 and Figure 4 The bottom surface of the mounting plate 14 is fixedly connected to a second shock-absorbing pad 16. The second shock-absorbing pad 16 has through holes corresponding to the mounting holes 15. The second shock-absorbing pad 16 can effectively absorb the vibration energy of the twisting machine during operation, further reduce the vibration and noise generated by the entire mechanism during operation, and improve the stability and comfort of the equipment.

[0041] Please see Figure 1 , Figure 2 and Figure 5 Both the first damping pad 10 and the second damping pad 16 are made of rubber. Rubber has good elasticity and damping performance, which can effectively absorb and disperse vibration energy, reduce equipment vibration and noise. At the same time, rubber also has good wear resistance and corrosion resistance, which can extend the service life of the damping pad.

[0042] In this embodiment, a yarn bobbin for a twisting machine is provided with an elastic clamping member 2, which consists of a connecting part 201, an arc-shaped support part 202, and a bending part 203. The elastic deformation characteristics of the elastic clamping member 2 can absorb the vibration energy during operation, achieving a certain shock absorption effect and improving the installation stability of the yarn bobbin body 3. This effectively prevents the yarn bobbin body 3 from shaking or falling off in a high-vibration environment. By providing a first shock-absorbing pad 10 on the inner wall of the arc-shaped support part 202, the shock absorption effect on the yarn bobbin body 3 is further optimized. The movement and clamping action of the elastic clamping member 2 is realized through the linkage of the worm 8, the worm wheel 9, and the lead screw 4. This not only facilitates operation but also improves the positioning stability of the yarn bobbin body 3 by virtue of the self-locking characteristics of the worm 8 and the worm wheel 9.

[0043] It should be noted that handwheels are provided at both ends of the worm gear 8, which facilitates the rotation of the worm gear 8 via the handwheels. The elastic clamping part 2 is integrally formed.

[0044] The working principle of the above embodiments is as follows:

[0045] The mounting plate 14 can be fixed to the body of the twisting machine using bolts through the mounting holes 15 on the mounting plate 14. When it is necessary to support and position the yarn bobbin body 3, the yarn bobbin body 3 is placed in the center on the base 1. Then, the worm 8 is rotated. The worm 8 drives the lead screw 4 to rotate through the worm wheel 9. The lead screw 4 drives the connecting plate 6 and the back plate 7 to move inward through the threaded tube 5. The back plate 7 drives the elastic clamping member 2 to move inward. Then, the two elastic clamping members 2 clamp and fix the bottom of the yarn bobbin body 3 through the arc-shaped support part 202 and the first shock-absorbing pad 10. The arc-shaped support part 202 has a certain elastic deformation characteristic. Together with the first shock-absorbing pad 10, it can effectively absorb the vibration energy during the operation of the twisting machine, achieve a certain shock absorption effect, improve the installation stability of the yarn bobbin body 3, and effectively prevent the yarn bobbin body 3 from shaking or falling off in a high vibration environment.
