Description

Technical Field

[0001] The present application relates to the technical field of optical fiber cable cutting, and in particular to a noise reduction device for an optical fiber cable cutting machine. Background Art

[0002] Fiber optic cable cutting machines are widely used in the communications industry to cut and process optical fibers, playing an important role in improving the efficiency of optical fiber connections. With the development of communication technology and the increase in market demand, fiber optic cable cutting machines are widely used in production lines.

[0003] A common fiber optic cable cutting machine in the prior art includes a frame with a fixed cutting table mounted on it, a slidable cutter mounted above the table, and several rotating traction rollers within the frame. These rollers are used to pull the optical fiber into and out of the space between the cutting table and the cutter. However, each traction roller requires a motor to drive it, resulting in a large number of motors in the entire cutting mechanism.

[0004] When multiple motors operate simultaneously, they generate a significant amount of noise, polluting the work environment. This is especially true when multiple motors operate simultaneously, where the noise they generate overlaps, creating a strong acoustic interference that significantly impacts the operator's hearing and work comfort. This noise problem not only creates a harsh working environment but can also reduce worker efficiency. Utility Model Content

[0005] In order to effectively reduce the noise generated by an optical fiber cable cutting machine during operation and improve the working environment, the present application provides a noise reduction device for an optical fiber cable cutting machine.

[0006] The present application provides a noise reduction device for an optical fiber cable cutting machine using the following technical solutions:

[0007] A noise reduction device for an optical fiber cable cutting machine includes a silencer box arranged on the side of the optical fiber cable cutting machine, the silencer box includes an inner plate, an outer plate, and a side plate, the inner plate is located on the side of the silencer box close to the optical fiber cable cutting machine, the outer plate is located on the side of the silencer box away from the optical fiber cable cutting machine, the side plate is arranged around the inner plate and the outer plate, one side of the side plate is fixedly connected to the inner plate, and the other side of the side plate is fixedly connected to the outer plate, a through hole is formed through the inner plate, the through hole is used for the motor of the optical fiber cable cutting machine to pass through and extend into the silencer box, and a first sound insulation cotton is adhered to the inner wall surface of the silencer box.

[0008] By adopting the above technical solution, when the optical fiber cable cutting machine is working, the noise generated by the motor operation is transmitted inside the silencer box, and the first sound insulation cotton adhered to the inner wall surface of the silencer box absorbs and blocks the incoming noise, reducing the transmission intensity of the noise, thereby reducing the adverse effects of the noise on the external environment and improving the working environment.

[0009] Preferably, a plurality of heat dissipation holes are formed through the side plate.

[0010] By adopting the above technical solution, the provision of the heat dissipation holes can ensure that the heat generated by the motor in the muffler box during operation is dissipated in a timely manner, thereby preventing the motor from overheating and causing malfunction or performance degradation.

[0011] Preferably, a first folding plate and a second folding plate are provided in the silencer box, and the first folding plate and the second folding plate are both arranged around the through hole. The first folding plate is fixedly mounted on the inner plate, and the cross section of the first folding plate is inclined to the surface of the inner plate. The second folding plate is fixedly mounted on the outer plate, and the cross section of the second folding plate is inclined to the surface of the outer plate. The first folding plate and the second folding plate are parallel to each other.

[0012] By adopting the above technical solution, when the noise sound waves propagate around at the through hole in the silencer box, the sound waves experience multiple reflections inside the silencer box. The first folding plate and the second folding plate extend the propagation path of the sound waves. In this process, the energy of the sound waves is continuously consumed, thereby achieving a noise reduction effect and avoiding the noise sound waves from directly escaping from the heat dissipation holes as much as possible.

[0013] Preferably, the second folding plate is located on a side of the first folding plate close to the through hole.

[0014] By adopting the above technical solution, the second folding plate is located on the side of the first folding plate close to the through hole. During the propagation process, the sound waves emitted by the motor preferentially enter the gap between the second folding plate and the inner plate, making it easier for the noise sound waves to enter between the second folding plate and the first folding plate.

[0015] Preferably, the first folded plate cross section is inclined on the inner plate in a direction away from the through hole, and the second folded plate cross section is inclined on the outer plate in a direction close to the through hole.

[0016] By adopting the above technical solution, the sound waves emitted by the motor are guided in the propagation path of the sound waves in the silencer box during the propagation process. When the sound waves are reflected between the second folding plate and the first folding plate, the sound waves propagate outward away from the through hole.

[0017] Preferably, a first connecting plate is integrally formed on the first folding plate, and the first connecting plate is riveted to the inner plate; and a second connecting plate is integrally formed on the second folding plate, and the second connecting plate is riveted to the outer plate.

[0018] By adopting the above technical solution, the integrally formed first folding plate and the first connecting plate, the second folding plate and the second connecting plate ensure the stability and reliability of the connection between the folding plate and the plate body, which is convenient for production. Then, through the riveted installation method, the first folding plate is installed on the inner plate and the second folding plate is installed on the outer plate. It can also provide a reliable connection, facilitate subsequent installation and maintenance, and facilitate the replacement of the sound insulation cotton.

[0019] Preferably, second sound insulation cotton is adhered to the surfaces of the first folding plate, the second folding plate, the first connecting plate, and the second connecting plate.

[0020] By adopting the above technical solution, the second sound insulation cotton can more effectively capture and consume the energy of sound waves, increase the speed at which the energy of sound waves is consumed, and thus further improve the overall noise reduction effect of the silencer box.

[0021] Preferably, a sound absorbing panel is fixedly mounted on one side of the outer panel close to the inner panel, and the sound absorbing panel is provided with sound absorbing holes, and a plurality of the sound absorbing holes are distributed in a honeycomb pattern.

[0022] By adopting the above technical solution, when sound waves propagate to the sound-absorbing panel, the sound-absorbing holes can cleverly guide the propagation direction of the sound waves, causing the sound waves to be scattered and absorbed inside the sound-absorbing holes, further attenuating the energy of the sound waves and reducing the noise propagating outward.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up the silencer box, the first sound insulation cotton and the heat dissipation holes, the noise of the optical fiber cable cutting machine motor can be reduced while ensuring the normal heat dissipation of the motor, effectively improving the working environment;

[0025] 2. By setting the first folding plate, the second folding plate, and the second sound insulation cotton, the sound wave propagation path is extended, the sound wave energy is consumed, and the noise sound waves are prevented from directly escaping from the heat dissipation holes as much as possible, thereby ensuring the noise reduction effect;

[0026] 3. By setting up sound-absorbing panels and honeycomb sound-absorbing holes, the sound waves are further guided and absorbed, the noise propagating outward is reduced, and the overall noise reduction capability is enhanced. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The embodiment of the present application discloses a noise reduction device for an optical fiber cable cutting machine. Figure 1 and Figure 2 The size of the silencer box 1 is customized according to the size and number of the motors 21 on the optical fiber cable cutting machine 2 to ensure that all the motors 21 are fully covered. The silencer box 1 includes an inner panel 11, an outer panel 12, and a side panel 13. The inner panel 11 is located on the side of the silencer box 1 close to the optical fiber cable cutting machine 2, and the outer panel 12 is located on the side of the silencer box 1 away from the optical fiber cable cutting machine 2. The side panel 13 is arranged around the inner panel 11 and the outer panel 12. One side of the side panel 13 is fixedly connected to the inner panel 11, and the other side of the side panel 13 is fixedly connected to the outer panel 12. The inner panel 11, the outer panel 12, and the side panel 13 together form a closed space. The connection method can be bolted to ensure the connection strength while facilitating opening. A number of heat dissipation holes 131 can be opened through the side panel 13 to ensure that the heat generated by the motor 21 is dissipated in time to prevent the motor 21 from overheating and causing failure.

[0033] Reference Figure 2 and Figure 3 The inner plate 11 is provided with a through hole 111 for the motor 21 of the optical fiber cable cutter 2 to pass through and extend into the muffler box 1. A first sound insulation foam is adhered to the inner wall surface of the muffler box 1. If the position of the motor 21 on the frame is fixed, the through hole 111 is directly provided around the motor 21. If the position of the motor 21 on the frame is not fixed, the through hole 111 is provided around the motion trajectory of the motor 21.

[0034] Reference Figure 2 and Figure 3 A sound absorbing plate 123 is fixedly mounted on one side of the outer plate 12 close to the inner plate 11, and a sound absorbing hole 1231 is opened on the sound absorbing plate 123. The shape of the sound absorbing hole 1231 can be designed to be honeycomb-shaped, so that when the sound wave propagates to the sound absorbing hole 1231, it can be scattered and reflected and absorbed inside.

[0035] Reference Figure 2 and Figure 3The silencer box 1 is provided with a first folding plate 112 and a second folding plate 121. A first connecting plate 113 is integrally formed on the first folding plate 112. The first connecting plate 113 is riveted to the inner plate 11. The first folding plate 112 is fixedly mounted on the inner plate 11 via the first connecting plate 113. The cross-section of the first folding plate 112 is inclined to the surface of the inner plate 11. A second connecting plate 122 is integrally formed on the second folding plate 121. The second connecting plate 122 is riveted to the sound-absorbing plate 123 on the outer plate 12. The second folding plate 121 is fixedly mounted on the outer plate 12 via the second connecting plate 122. The cross-section of the second folding plate 121 is inclined to the outer surface. The first folding plate 112, the second folding plate 121, the first connecting plate 113, and the second connecting plate 122 are all made of steel plates or engineering plastics, with good mechanical strength and durability, and a second sound insulation cotton is adhered to their surfaces.

[0036] Reference Figure 2 and Figure 3 The first folded plate 112 and the second folded plate 121 are arranged parallel to each other. Specifically, the second folded plate 121 is located on the side of the first folded plate 112 closest to the through hole 111. The cross-section of the first folded plate 112 on the inner plate 11 is tilted away from the through hole 111, while the cross-section of the second folded plate 121 on the outer plate 12 is tilted toward the through hole 111. The first and second folded plates 112 and 121 extend the propagation path of sound waves within the silencer box 1, increasing the number of sound wave reflections within the silencer box 1, thereby consuming more sound wave energy and improving the overall noise reduction effect.

[0037] The operating principle of this embodiment is as follows: When the optical fiber cable cutter 2 is operating, the noise generated by the motor 21 is transmitted to the muffler box 1. Some of the noise waves enter the sound-absorbing plate 123, where they are scattered and reflected and absorbed within the sound-absorbing holes 1231. The muffler provides initial absorption and blocking, reducing direct noise transmission. Another portion of the noise waves enters the area between the first folded plate 112 and the second folded plate 121. Due to the inclined arrangement of the first and second folded plates 112, 121, the sound waves reflect multiple times between the first and second folded plates 112, 121, extending the propagation path and continuously dissipating the sound wave energy during the reflection process. Simultaneously, the second sound-insulating cotton adhered to the surfaces of the first and second folded plates 112, 121, and the first and second connecting plates 113, 122 further absorbs and dissipates the sound wave energy. By the time the sound waves reach the heat dissipation holes 131, they are significantly attenuated. This effectively reduces the noise generated by the motor 21, reduces outward noise transmission, improves the working environment, and ensures the health and comfort of the operator.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
