Description

Technical Field

[0001] This utility model relates to the field of noise reduction idler technology, specifically to a noise reduction idler coated with a polymer elastic material. Background Technology

[0002] As a core supporting component of conveyor belt systems, idlers' operational stability and noise control directly affect conveying efficiency, working environment, and equipment maintenance costs. With the increasing stringency of noise pollution control in industrial production, noise-reducing idlers coated with polymer elastic materials are gradually replacing traditional metal idlers because they can absorb frictional vibration noise through the elastic coating layer. However, existing noise-reducing idlers coated with polymer elastic materials still have significant technical defects in practical applications, especially in bearing sealing and noise interception, making it difficult to meet the requirements for low noise and long service life.

[0003] In the process of developing this application, the following problems were found in the technology: Existing noise control of noise-reducing idlers mostly rely on the polymer elastic coating layer on the outer circumference, ignoring the noise source at the joint between the idler shaft and the bearing. When the idler is running, the rolling friction between the inner ring of the bearing and the roller, and between the roller and the outer ring, will generate high-frequency noise, and this noise will be directly leaked out through the gap between the bearing and the idler housing, thus reducing the practicality of the equipment.

[0004] To address this, a noise-reducing idler roller coated with a polymer elastic material is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a noise-reducing idler roller coated with a polymer elastic material to solve the problems mentioned in the background art.

[0006] A noise-reducing idler roller coated with a polymer elastic material includes an idler roller with bearings on both the upper and lower sides. The outer ends of the two sets of bearings are fitted with sealing components that block and seal the openings of the two sets of bearings. A reset component is installed on the outer end of the sealing component, and a connecting ring is installed inside the sealing component.

[0007] Furthermore, the sealing assembly includes two sets of protective cover plates, which are respectively attached to opposite sides of the two sets of bearings. An annular sealing plate is slidably connected to the outer ends of both sets of protective cover plates. The annular sealing plates are respectively sleeved on the outer ends of the two sets of bearings. Two sets of grooves are formed on the outer surface of the bearings. Positioning frames are slidably connected inside the two sets of grooves. Limiting springs are installed inside the two sets of positioning frames. The ends of the limiting springs furthest from the positioning frames are respectively installed inside the two sets of grooves of the bearings. Two sets of positioning holes are formed on the outer surface of the annular sealing plate. The positions of the two sets of positioning frames are respectively located on the movement paths of the two sets of positioning holes.

[0008] Furthermore, the reset assembly includes multiple sets of elastic bands, which are respectively disposed on the outer surfaces of the two sets of annular sealing plates. A plug is installed on the side of the elastic band near the annular sealing plate, and the end of the plug away from the elastic band is inserted into the positioning hole of the annular sealing plate.

[0009] Furthermore, a fixing plate is installed on the inner wall of the connecting ring, and a groove is formed inside the fixing plate. A magnetic plate is installed inside the groove of the fixing plate, and the side of the magnetic plate near the idler roller is adsorbed onto the side of the protective cover away from the idler roller.

[0010] Furthermore, an annular sealing gasket is adhered to the side of the protective cover plate near the idler roller, and the side of the annular sealing gasket away from the protective cover plate is attached to the side of the bearing away from the idler roller.

[0011] Furthermore, multiple sets of slots are provided on the side of the bearing away from the idler roller, and limit plates are inserted into the multiple sets of slots of the bearing. The multiple sets of limit plates are installed on the side of the protective cover plate near the idler roller on the side away from the bearing.

[0012] Furthermore, the outer surface of the idler roller is provided with a foamed elastomer composite sleeve.

[0013] The beneficial effects of this utility model are as follows: 1. This utility model involves pushing the protective cover plate to adhere it to the side of the bearing away from the idler roller. At this time, the annular sealing plate is pushed to fit onto the outer end of the bearing. As the annular sealing plate slides on the outer end of the bearing, it presses the positioning frame to reset and adjust it into the groove inside the bearing. Then, a limiting spring is installed inside the positioning frame. When the positioning frame is adjusted and moved to a position parallel to the positioning hole of the annular sealing plate, the limiting spring uses its own elastic potential energy to push the positioning frame to move, locking the positioning frame into the positioning hole of the annular sealing plate. This allows the sealing assembly to fit onto the outer end of the bearing, thereby intercepting the noise generated between the idler roller and the bearing, reducing the impact of excessive noise on surrounding personnel, and thus improving the practicality of the device.

[0014] 2. This utility model moves the insertion rod by pushing the elastic belt. At this time, the insertion rod slides inside the positioning hole of the annular sealing plate. Then, the positioning frame is inserted into the positioning hole of the annular sealing plate, so that when the insertion rod slides, it pushes the positioning frame to reset and move into the groove of the bearing. This allows the operator to disassemble the sealing assembly without taking tools, thereby shortening the time spent by the operator when disassembling and moving the sealing assembly, thus improving the practicality of the device.

[0021] like Figures 1 to 5 As shown, a noise-reducing idler roller covered with a polymer elastic material includes an idler roller 1. Bearings 3 are provided on both the upper and lower sides of the idler roller 1. A sealing component 4 is sleeved on the outer end of the two sets of bearings 3 to block and seal the openings of the two sets of bearings 3. A reset component 5 is installed on the outer end of the sealing component 4, and a connecting ring 8 is installed inside the sealing component 4. Specifically, by pushing the sealing component 4, the sealing component 4 is sleeved on the outer end of the bearing 3, so that the sealing component 4 can intercept the noise generated between the idler roller 1 and the bearing 3, thereby reducing the impact of loud noise on surrounding personnel, thus improving the practicality of the device. By sleeved on the outer end of the bearing 3, the sealing component 4 can be quickly installed and removed by the staff, which facilitates the subsequent maintenance of the connection between the bearing 3 and the idler roller 1.

[0022] The sealing assembly 4 includes two sets of protective cover plates 403, which are respectively attached to opposite sides of the two sets of bearings 3. The outer ends of the two sets of protective cover plates 403 are slidably connected to annular sealing plates 402. The two sets of annular sealing plates 402 are respectively sleeved on the outer ends of the two sets of bearings 3. The outer surface of the bearing 3 has two sets of grooves. The two sets of grooves of the bearing 3 are slidably connected to positioning frames 401. The two sets of positioning frames 401 are each installed with a limit spring 404. The ends of the two sets of limit springs 404 away from the positioning frames 401 are respectively installed in the two sets of grooves of the bearing 3. The outer surface of the annular sealing plate 402 has two sets of positioning holes. The positions of the two sets of positioning frames 401 are respectively located on the movement paths of the two sets of positioning holes. Specifically, by pushing the protective cover plate 403 to adhere it to the side of the bearing 3 away from the idler roller 1, the annular sealing plate 402 is pushed and fitted onto the outer end of the bearing 3. When the annular sealing plate 402 slides on the outer end of the bearing 3, it presses the positioning frame 401 to reset and adjust it into the groove of the bearing 3. Then, a limiting spring 404 is installed inside the positioning frame 401. When the positioning frame 401 is adjusted and moved to a position parallel to the positioning hole of the annular sealing plate 402, the limiting spring 404 uses its own elastic potential energy to push the positioning frame 401 to move, locking the positioning frame 401 into the positioning hole of the annular sealing plate 402. This allows the sealing component 4 to be fitted onto the outer end of the bearing 3, thereby intercepting the noise generated between the idler roller 1 and the bearing 3, reducing the impact of loud noise on surrounding personnel, thus improving the practicality of the device. By fitting the sealing component 4 onto the outer end of the bearing 3, the sealing component 4 can be quickly installed and removed by the staff, facilitating subsequent maintenance of the connection between the bearing 3 and the idler roller 1.

[0023] The reset assembly 5 includes multiple sets of elastic bands 501, which are respectively disposed on the outer surfaces of two sets of annular sealing plates 402. A rod 502 is installed on the side of the elastic band 501 near the annular sealing plate 402, and the end of the rod 502 away from the elastic band 501 is inserted into the positioning hole of the annular sealing plate 402. Specifically, by pushing the elastic band 501, the rod 502 is moved. At this time, the rod 502 slides inside the positioning hole of the annular sealing plate 402, and then the positioning frame 401 is inserted into the positioning hole of the annular sealing plate 402. When the rod 502 slides, it pushes the positioning frame 401 to reset and move into the groove of the bearing 3. This allows the operator to disassemble the sealing assembly 4 without taking tools, thereby shortening the time spent by the operator when disassembling and moving the sealing assembly 4, and thus improving the practicality of the device.

[0024] A fixing plate 6 is installed on the inner wall of the connecting ring 8. The fixing plate 6 has a groove inside, and a magnetic plate 7 is installed inside the groove. The side of the magnetic plate 7 near the idler roller 1 is attracted to the side of the protective cover plate 403 away from the idler roller 1. Specifically, by pushing the annular sealing plate 402, the side of the magnetic plate 7 near the idler roller 1 is attracted to the side of the protective cover plate 403 away from the idler roller 1. This restricts the sliding position of the annular sealing plate 402 at the outer end of the protective cover plate 403, preventing the annular sealing plate 402 from shaking during use, thus improving the stability of the annular sealing plate 402 during use.

[0025] An annular sealing gasket 10 is adhered to the side of the protective cover plate 403 near the idler roller 1, and the side of the annular sealing gasket 10 away from the protective cover plate 403 is attached to the side of the bearing 3 away from the idler roller 1. Specifically, by pushing the two sets of protective covers 403, the two sets of annular sealing gaskets 10 are respectively attached to the connection between the two sets of protective covers 403 and the two sets of bearings 3, so that the two sets of annular sealing gaskets 10 seal the connection between the two sets of protective covers 403 and the two sets of bearings 3, preventing the noise generated inside the bearing 3 from spreading outward along the connection between the bearing 3 and the protective cover plate 403, thus improving the noise reduction effect of the sealing assembly 4.

[0026] Multiple slots are provided on the side of bearing 3 away from idler roller 1. Each slot of bearing 3 is fitted with a limiting plate 9. The side of the limiting plate 9 away from bearing 3 is installed on the side of protective cover 403 near idler roller 1. Specifically, by pushing protective cover 403, the multiple limiting plates 9 are inserted into the slots of bearing 3, allowing workers to quickly put the sealing component 4 onto the outer end of bearing 3. This shortens the time spent by workers installing the sealing component 4 onto the outer end of two sets of bearings 3, thus improving the practicality of the device.

[0027] The outer surface of the idler roller 1 is provided with a foamed elastomer composite sleeve 2. Specifically, the foamed elastomer composite sleeve 2 adopts a composite structure of an inner foamed elastomer and an outer dense wear-resistant layer. At this time, the inner foamed material is used to efficiently absorb noise and vibration, and the outer dense layer ensures the wear resistance of the foamed elastomer composite sleeve 2. This allows the foamed elastomer composite sleeve 2 to simultaneously achieve noise reduction effect and service life, thus improving the practicality of the device.

[0028] In summary: By pushing the protective cover plate 403 to adhere it to the side of the bearing 3 away from the idler roller 1, the annular sealing plate 402 is pushed to fit onto the outer end of the bearing 3. When the annular sealing plate 402 slides on the outer end of the bearing 3, it presses the positioning frame 401 to reset and adjust it into the groove of the bearing 3. Then, a limiting spring 404 is installed inside the positioning frame 401. When the positioning frame 401 is adjusted and moved to a position parallel to the positioning hole of the annular sealing plate 402, the limiting spring 404 uses its own elastic potential energy to push the positioning frame 401 to move, thus engaging the positioning frame 401 into the positioning hole of the annular sealing plate 402. This allows the sealing assembly 4 to be fitted onto the outer end of the bearing 3, thereby intercepting the noise generated between the roller 1 and the bearing 3, thus reducing the impact of excessive noise on surrounding personnel. By pushing the elastic band 501, the insertion rod 502 is moved. At this time, the insertion rod 502 slides inside the positioning hole of the annular sealing plate 402, and then the positioning frame 401 is inserted into the positioning hole of the annular sealing plate 402. When the insertion rod 502 slides, it pushes the positioning frame 401 to reset and move into the groove of the bearing 3. This allows the workers to remove the sealing assembly 4 without taking tools, thus shortening the time spent by the workers in removing and moving the sealing assembly 4.
