Description

Technical Field

[0001] This utility model relates to the field of rubber processing technology, and more specifically, to a noise reduction device for rubber processing. Background Technology

[0002] The history of rubber processing dates back to ancient times, especially when humans began using natural rubber. With industrial development, the demand for rubber products has increased, and cutting and processing techniques have also evolved.

[0003] The use of machinery such as rubber cutters during rubber processing generates high-intensity noise. Prolonged exposure to this noise environment can cause irreversible damage to workers' hearing, even leading to hearing loss or deafness. Therefore, we propose a noise reduction device for the rubber processing process. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a liftable camera device.

[0005] This utility model discloses a noise reduction device for rubber processing, including a workbench. A limit assembly is fixedly connected to the outer wall of the workbench. A transmission roller is rotatably connected to the workbench. A U-shaped frame is fixedly connected to the workbench. A hydraulic cylinder is fixedly connected to the outer wall of the U-shaped frame. A cutting blade is fixedly connected to the piston rod of the hydraulic cylinder. A sliding noise reduction device is provided on the U-shaped frame. An auxiliary noise reduction device is provided on the sliding noise reduction device. The sliding noise reduction device includes:

[0006] A rotating roller is rotatably connected in a sliding groove on the U-shaped frame, and multiple sets of the rotating roller are provided.

[0007] A bevel gear one is fixedly connected to the rotating roller, and the bevel gear one is meshed with a bevel gear two.

[0008] The rotating rod is fixedly connected to the bevel gear two, and the rotating rod is rotatably connected in the sliding groove.

[0009] Preferably, the auxiliary noise reduction device includes a bevel gear three, and the bevel gear three is meshed with the side of the bevel gear two away from the bevel gear two, so that the rotation of the bevel gear two drives the rotation of the bevel gear three.

[0010] Preferably, the bevel gear three is fixedly connected to the rotating disk, and the rotating disk is rotatably connected in the sliding groove.

[0011] Preferably, an extrusion plate is fixedly connected to the outer wall of the rotating disk, and a movable groove is provided on the sliding groove. When the rotation of the rotating disk drives the extrusion plate to rotate to the edge of the sliding groove, it approaches the movable groove.

[0012] Preferably, the movable trough is provided with an oil storage tank, and a movable plate is provided on the lower side of the oil storage tank. The oil in the oil storage tank is in an open state, but cannot flow out due to the limitation of the movable trough and the movable plate.

[0013] Preferably, the movable plate is slidably connected in the movable groove, and the surface of the movable plate is provided with through holes. The movable plate and the sliding groove are elastically connected by a spring. When the pressing plate approaches the movable groove, it can press the movable plate in front of the movable groove, and the movable plate is forced to contract into the movable groove.

[0014] Preferably, the surface of the movable plate is provided with a through hole, and the movable plate and the sliding groove are elastically connected by a spring.

[0015] Preferably, the through hole is located on the outside of the movable groove.

[0016] The beneficial effects of this application are as follows:

[0017] 1. This noise reduction device for rubber processing uses a sliding noise reduction mechanism. When the cutting blade and other working components slide in the sliding groove, they drive the rotation of the rotating roller. The rotation of the rotating roller drives the meshing motion of bevel gear one and bevel gear two, making the rotation of the rotating roller more stable. The bevel gear transmission system itself has a certain shock absorption effect. When the cutting blade generates impact during the lifting and lowering process, the meshing of the bevel gears can absorb some of the impact energy, thereby reducing noise generation, reducing the noise generated by the unstable rotation of the rotating roller, improving the working environment, and increasing work efficiency.

[0018] 2. This rubber processing noise reduction device, through an auxiliary noise reduction device, drives the rotation of bevel gear three via meshing connection when bevel gear two rotates. The rotation of the rotating disk drives the extrusion plate to rotate to the edge of the sliding groove, extruding the movable plate in front of the movable groove. The movable plate is forced to contract into the movable groove until the through hole on the movable plate enters the movable groove, and the open oil reservoir is transmitted out of the movable groove through the through hole to lubricate the various working components. This significantly reduces the direct contact and friction between metal parts, thereby reducing the noise generated by friction. Attached Figure Description

[0030] To further understand the utility model's content, features, and effects, the following embodiments are provided, along with detailed descriptions in conjunction with the accompanying drawings:

[0031] Reference Figure 1 The noise reduction device for rubber processing in this embodiment includes a workbench 1, a limit assembly 2 fixedly connected to the outer wall of the workbench 1, a transmission roller 3 rotatably connected to the workbench 1, a U-shaped frame 4 fixedly connected to the workbench 1, a hydraulic cylinder 501 fixedly connected to the outer wall of the U-shaped frame 4, a cutting blade 502 fixedly connected to the piston rod of the hydraulic cylinder 501, a sliding noise reduction device 6 provided on the U-shaped frame 4, an auxiliary noise reduction device 7 provided on the sliding noise reduction device 6, and the sliding noise reduction device 6 includes a rotating roller 61.

[0032] In this embodiment of the utility model, in order to improve the working environment and increase work efficiency, specifically, a rotating roller 61 is rotatably connected in the sliding groove on the U-shaped frame 4, and multiple sets of rotating rollers 61 are provided. When the working components such as the cutting blade 502 slide in the sliding groove, they drive the rotation of multiple sets of rotating rollers 61. A bevel gear 62 is fixedly connected to the rotating roller 61, and the bevel gear 62 meshes with a bevel gear 63. The bevel gear 63 is fixedly connected to the rotating rod 64, and the rotating rod 64 is rotatably connected in the sliding groove. Through the meshing motion of the bevel gear 62 and the bevel gear 63, the rotation of the rotating roller 61 is made more stable. The bevel gear transmission system itself has a certain shock absorption effect. When the cutting blade 502 generates an impact during the lifting and lowering process, the meshing of the bevel gears can absorb part of the impact energy, thereby reducing the generation of noise and reducing the noise generated by the unstable rotation of the rotating roller 61.

[0033] In this embodiment of the invention, in order to reduce frictional resistance and noise caused by vibration and impact, the auxiliary noise reduction device 7 specifically includes a bevel gear 71. The bevel gear 71 is meshed with the side of the bevel gear 63 away from the bevel gear 63. The rotation of the bevel gear 63 drives the rotation of the bevel gear 71. The bevel gear 71 is fixedly connected to a rotating disk 72, which is rotatably connected in a sliding groove. A pressing plate 73 is fixedly connected to the outer wall of the rotating disk 72, and a movable groove 74 is provided on the sliding groove. When the rotating disk 72 rotates, it drives the pressing plate 73... When rotated to the edge of the sliding groove, it approaches the movable groove 74. The movable groove 74 is provided with an oil storage tank 75, and a movable plate 76 is provided on the lower side of the oil storage tank 75. The oil in the oil storage tank 75 is in an open state, but it cannot flow out due to the limitation of the movable groove 74 and the movable plate 76. The movable plate 76 is slidably connected in the movable groove 74, and a through hole 77 is opened on the surface of the movable plate 76. The movable plate 76 and the sliding groove are elastically connected by a spring 78. When the extrusion plate 73 approaches the movable groove 74, it can extrude the movable plate 76 in front of the movable groove 74. The movable plate 76 is forced to retract into the movable groove 74.

[0034] In use, when the cutting blade 502 and other working components slide in the sliding groove, they drive the rotation of the rotating roller 61. The rotation of the rotating roller 61 drives the meshing motion of bevel gear 62 and bevel gear 63, making the rotation of the rotating roller 61 more stable. The bevel gear transmission system itself has a certain shock absorption effect. When the cutting blade 502 generates impact during lifting and lowering, the meshing of the bevel gears can absorb some of the impact energy, thereby reducing noise generation and reducing the noise generated by the unstable rotation of the rotating roller 61, improving the working environment and increasing work efficiency. As gear 2 63 rotates, it drives the rotation of bevel gear 3 71 through meshing connection. The rotation of rotating disk 72 drives extrusion plate 73 to rotate to the edge of sliding groove, extruding movable plate 76 in front of movable groove 74. Movable plate 76 is forced to retract into movable groove 74 until through hole 77 on movable plate 76 enters movable groove 74. The open oil reservoir 75 is transmitted out of movable groove 74 through through hole 77 to lubricate the various working components, significantly reducing direct contact and friction between metal parts, thereby reducing noise caused by friction.

[0035] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
