Description

Technical Field

[0001] This utility model relates to the field of color sorters, and in particular to a bearing sealing and protection structure for a color sorter track machine and a color sorter. Background Technology

[0002] The working principle of the color sorting track machine's main drive is as follows: after the material is fed by the vibrator, it enters the main drive, accelerates on the conveyor belt, and eventually reaches a relative standstill. Then, it is ejected from the front end of the main drive in a stable manner. After passing the camera's observation point, it is blown out by compressed gas from the rejection mechanism at the lower part of the main drive. The main drive has side guards and silicone pads on both sides. This structure is adjustable up and down, ensuring that the silicone pads are close enough to the conveyor belt but do not contact it. This prevents material from rolling and overflowing from the sides of the main drive when the material is fed by the front vibrator.

[0003] Currently, the color sorting tracked machine performs stably when dry-sorting materials with low dust content. However, when sorting materials containing moisture or high dust content, water and dust overflow from the gaps between the left and right side guards of the main drive and the conveyor, eventually landing on the bearing at the discharge end. Simultaneously, when the material is blown out by compressed gas at the blowing point, water and impurities carried along with it are ejected and splashed onto the bearing at the discharge end. Furthermore, when the material contains moisture or high dust content, bearing guards are generally not installed to prevent material accumulation at the bearing. This leaves the bearing unprotected, leading to a continuous accumulation of water, impurities, and dust on the bearing surface. This dust enters the bearing through the bearing dust seal, accumulating and causing the high-speed rotating bearing to jam, overheat, and ultimately damage itself. Utility Model Content

[0004] To address the technical problem of short bearing lifespan due to damage, this utility model provides a bearing sealing and protection structure for a color sorting track machine and a color sorter.

[0005] This utility model is achieved using the following technical solution: a sealing and protective structure for a color sorting track bearing, comprising a seated bearing and a dustproof main seat for mounting the seated bearing, wherein a rubber pad is provided between the seated bearing and the dustproof main seat, and a rubber ring, a pad plate, and a dustproof cover are sequentially provided on the side of the seated bearing away from the dustproof main seat, the dustproof cover being connected to the dustproof main seat, and a wool felt, a pressure plate, a rubber ring, and a sealing plate are sequentially provided on the other side of the dustproof main seat, the sealing plate being connected to the dustproof main seat, and an mounting plate connected to the seated bearing being connected to one side of the dustproof main seat.

[0006] As a further improvement to the above scheme, the dust cover is connected with multiple bolts 1 that are connected to the dust cover main seat, the sealing plate is connected with multiple bolts 2 that are connected to the dust cover main seat, and the mounting plate is connected with bolts 3 that pass through one side of the bearing seat, with one end of bolt 3 connected to the dust cover main seat.

[0007] As a further improvement to the above solution, a mounting hole for installing wool felt and pressure plate is provided on one side of the dustproof main seat, and a bearing hole is provided on the sealing plate.

[0008] As a further improvement to the above solution, a limit post is provided on the outer ring of the bearing with housing, and a limit groove is provided on the dustproof main seat for the limit post to pass through.

[0009] A color sorter includes a protective housing for protection, a belt connected inside the protective housing, specific bearings connected to the protective housing at both support ends of the belt, a power assembly connected to the protective housing at one of the support ends of the protective housing, a filter collection box connected to the bottom of the protective housing, a vacuum pump connected to the bottom of the filter collection box, an ejector fixedly connected to one side of the filter collection box, a rotator connected inside the ejector, a spray nozzle located below the belt connected to the rotator, multiple cameras connected to the ejector, a telescopic rod connected to one side of the ejector, a collection frame connected to the moving end of the telescopic rod, and multiple spray pipes connected to the middle of the collection frame.

[0010] As a further improvement to the above solution, the camera is equipped with a protective plate that is fixedly connected to the sprayer, and the filter collection box is filled with filter material.

[0011] As a further improvement to the above solution, a monitoring device is fixedly connected to one side of the collection box. The cross-section of the monitoring device adopts a W-shaped structure, and an opening located below the belt is provided on one side of the filter collection box.

[0012] As a further improvement to the above solution, side strips are fixedly connected to both sides of the belt, and a protective strip that slides and engages with the side strips is fixedly connected inside the protective box. The protective strip has a U-shaped cross-section, and a vibrating screen is connected to one side of the protective box.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By adding dustproof and waterproof gaskets to both ends of the bearing, the dustproof and waterproof gaskets can fully prevent dust and water damage and are wear-resistant. At the same time, the structure can be extended to create more layers of sealing according to the actual operating space and the requirements of the protection level, so as to meet different levels of protection needs.

[0015] 2. By providing appropriate protection for belt 2, the emission of dust or water mist is reduced. At the same time, the collection and absorption of the filter collection box reduces overflow and the adsorption of impurities on the bearing, thereby further extending the service life of the bearing. In addition, the adjustable collection frame and spray pipe further assist in screening to ensure the classification of materials, thereby further reducing the possible dust and meeting the needs of the work.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Example 1:

[0025] Please combine Figure 1-3A sealing and protective structure for a color sorting track machine bearing includes a mounted bearing 05 and a dustproof main seat 07 for mounting the mounted bearing 05. The dustproof main seat 07 limits, installs, and protects the mounted bearing 05, while also facilitating easy installation during use. A rubber gasket 06 is provided between the mounted bearing 05 and the dustproof main seat 07, protecting the mounted bearing 05. On the side of the mounted bearing 05 away from the dustproof main seat 07, a rubber ring 04, a gasket 03, and a dust cover 02 are sequentially arranged. The rubber ring 04 seals one side of the mounted bearing 05. Plate 03 increases the contact area between dust cover 02 and rubber ring 04 to ensure the sealing of rubber ring 04. Dust cover 02 is connected to dust cover main seat 07. On the other side of dust cover main seat 07, wool felt 08, pressure plate 09, rubber ring 10 and sealing plate 11 are arranged in sequence. Wool felt 08 protects and seals the bearing 05 with seat. Pressure plate 09 increases the contact area. Rubber ring 10 also provides sealing. Sealing plate 11 is connected to dust cover main seat 07. One side of dust cover main seat 07 is connected to mounting plate 13 connected to bearing 05 with seat. Sealing plate 11 limits and seals one side.

[0026] The dust cover 02 is connected to multiple bolts 1 01 that are connected to the dust cover main seat 07. The sealing plate 11 is connected to multiple bolts 2 12 that are connected to the dust cover main seat 07. The mounting plate 13 is connected to a bolt 3 14 that passes through one side of the seated bearing 05. One end of the bolt 3 14 is connected to the dust cover main seat 07. Bolt 1 01 ensures the connection and fixation between the dust cover 02 and the dust cover main seat 07. Bolt 2 12 ensures the connection and fixation between the sealing plate 11 and the dust cover main seat 07. Bolt 3 14 ensures the fixation between the seated bearing 05, the mounting plates 13 and 17.

[0027] The dustproof main seat 07 has mounting holes on one side for installing wool felt 08 and pressure plate 09. The sealing plate 11 has bearing holes. The mounting holes ensure the passage of the shaft and the installation of some devices.

[0028] The outer ring of the mounted bearing 05 is provided with a limit post, and the dustproof main seat 07 is provided with a limit groove for the limit post to pass through. The limit post cooperates with the limit groove to realize the limitation of the mounted bearing 05.

[0029] The outer side of the mounted bearing 05 uses a dust cover 02, a gasket 03, and a rubber ring 04. These are tightened to the dustproof main seat 07 using bolts 01, forming a sealed cavity between the outer side of the mounted bearing 05 and the dust cover 02, providing dust protection for the outer side of the mounted bearing 05. This is the first layer of sealing. A rubber gasket 06 is used between the mounted bearing 05 and the dustproof main seat 07 to form a sealing layer, which is the second layer of sealing. The inner side of the mounted bearing 05 uses the dustproof main seat 07, felt 08, a second rubber ring 10, a pressure plate 09, and a sealing plate 11. The felt 08 and the second rubber ring 10 are installed in the inner groove of the dustproof main seat 07. The diameter of the inner groove is larger than the outer diameter of the felt 08 and the second rubber ring 10, used for automatically correcting dimensional deviations during bearing self-alignment, preventing the felt 08 and... When the bearing misaligns, the contact surface between the rubber ring 2 10 and the shaft will have a gap on one side and be too tight on the other side, causing wear. The felt 08 and the rubber ring 2 10 are separated by a pressure plate 09, which can both tighten and prevent excessive wear of the rubber ring 2 10 during relative rotation. The sealing plate 11 needs to be installed and locked after the bearing has completed self-alignment after working for a period of time. The outer diameter of this sealing plate 11 is the same as that of the dustproof main seat 07. It can both seal and protect the bearing 05 when it is disassembled with a puller. The above are the third and fourth layers of sealing. According to the inner groove depth of the dustproof main seat 07, the design can be extended. The greater the inner groove depth, the more felt 08 and rubber ring 2 10 can be installed, and the more sealing layers there are.

[0030] The hole spacing and diameter of mounting plate 13 are consistent with those of bearing 05, so no separate holes are needed. It can be added directly to the original mounting hole position, which can ensure the concentricity between bearing 05 and dustproof main seat 07. It can also be installed directly on the original equipment mounting hole without changing other structures or holes, making the operation simple.

[0031] The wool felt 08 and the rubber ring 210 are interference fit with the shaft. The wool felt 08 is dustproof and wear-resistant, and the rubber ring 210 is waterproof and wear-resistant.

[0032] Example 2:

[0033] Please combine Figure 1-5A color sorter includes a protective housing 20 for protection. A belt 21 is connected inside the protective housing 20. Specific bearings 32 connected to the protective housing 20 are connected to the two support ends of the belt 21. A power assembly 33 connected to the protective housing 20 is driven to one of the support ends of the protective housing 20, providing power to transport the raw materials via the belt 21 at a certain speed. The specific bearings 32 are bearings as described in this application, providing protection. A filter collection box 31 is connected to the bottom of the protective housing 20, and a vacuum pump 30 is connected to the bottom of the filter collection box 31. An ejector 29 is fixedly connected to one side of the filter collection box 31, and a rotor 23 is connected inside the ejector 29. The nozzle 24 is connected to the 23 below the belt 21. The rotator 23 is an existing mechanism that can rotate within the injector 29 to adjust the angle. The nozzle 24 discharges gas. The injector 29 is also an existing structure that performs forced gas flow. Multiple cameras 35 are connected to the injector 29. A telescopic rod 28 is connected to one side of the injector 29. A collection frame 27 is connected to the moving end of the telescopic rod 28. Multiple spray pipes 25 are connected to the middle of the collection frame 27. The cameras 35 perform optical sensing. The collection frame 27 can move to a certain extent under the push of the telescopic rod 28 to adapt to the collection needs. One end of the spray pipe 25 is connected to the injector 29 to discharge gas.

[0034] The camera 35 is equipped with a protective plate 36 that is fixedly connected to the sprayer 29. The filter collection box 31 is filled with filter material. The protective plate 36 is made of transparent material to protect the camera 35. The filter material in the filter collection box 31 performs filtration.

[0035] A monitor 26 is fixedly connected to one side of the collection box 27. The monitor 26 has a W-shaped cross-section. An opening located below the belt 21 is provided on one side of the filter collection box 31. The monitor 26 observes the amount of material stored in the collection box 27 to prevent overflow. The W-shaped structure enables the separation and storage of materials.

[0036] Side strips 22 are fixedly connected to both sides of the belt 21. A protective strip that slides and fits into the side strips 22 is fixedly connected inside the protective box 20. The protective strip has a U-shaped cross-section. A vibrating screen 34 is connected to one side of the protective box 20. Through the connection between the side strips 22 and the protective strip, some material can be reduced from overflowing from both sides of the belt 21, thereby reducing the accumulation of dust or water on the specific bearing 32 and helping to improve the overall service life of the lifting device.

[0037] The implementation principle of this application embodiment is as follows: During operation, the material is fed through the vibrating screen 34, then falls onto the belt 21, accelerates, and eventually reaches relative stillness. After that, it is thrown out from the front end of the belt 21 in a stable posture. After passing the view of the camera 35, the compressed gas blown out at the nozzle 24 of the injector 29 changes direction and enters different storage positions in the collection frame 27. The belt 21 has side strips 22 on the left and right sides to ensure that there is almost no gap between the belt 21 and the protective box 20. This ensures that when the vibrating screen 34 feeds material and when the belt 21 is transported, the material will not overflow from the left and right sides of the belt 21 due to rolling, thus reducing the spillage of dust.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
