[0002] The flaking machine roller is one of the core components of the flaking machine, which is used to roll metal sheets or other materials. The roller is made of high-strength steel or other alloys and has a specific shape and surface treatment to meet the requirements of different rolling processes.
[0003] The roller end sealing device is a sealing device installed at both ends of the roller. Its main function is to prevent the lubricant from leaking out and impurities from entering the bearing when the roller is rolling, and to prevent external impurities from entering the inside of the roller.
[0004] The roller end sealing devices in the prior art only have an internal sealing function, but lack an external sealing effect, which will cause external impurities to accumulate at the connection between the bearing seat and the roller. In the case of long-term use, the impurities are easy to enter the bearing seat, thereby affecting the sealing effect. Therefore, a roller end sealing device for a sheet rolling machine is proposed to solve the above problem. Utility Model Content

[0024] Reference Figure 1 , Figure 2 , Figure 4 The utility model provides an embodiment: a roller end sealing device for a sheet rolling machine, comprising a roller 1, a mounting seat 2 is fixedly connected to the rear end of the roller 1, a sealing baffle 3 is slidably connected to the front end of the mounting seat 2, levers 4 are slidably connected to the left and right sides of the front end of the mounting seat 2, two levers 4 are fixedly connected to the opposite sides of the cross bars 5, two cross bars 5 are fixedly connected to the opposite sides of the clamping blocks 6, support rods 7 are slidably connected to the inside of the two cross bars 5, compression springs 8 are fixedly connected to the opposite sides of the two cross bars 5, slide grooves 9 are opened on the left and right sides of the inside of the sealing baffle 3, a sealing assembly is provided on the periphery of the roller 1, and two clamping blocks 6 are slidably connected to the inside of the two slide grooves 9 respectively.
[0025] Specifically, the roller 1 is the main body of the sheet rolling machine roller, the mounting seat 2 is the connecting seat of the shaft end, the sealing baffle 3 is used to prevent external media from entering the interior of the mounting seat 2, and is also used to prevent the leakage of lubricating oil in the mounting seat 2, the lever 4 is used to facilitate the movement of the cross bar 5, the cross bar 5 is used to connect the lever 4 and the block 6, the support rod 7 is used to support the compression spring 8, the compression spring 8 is used to provide elastic support, the slide groove 9 is used to accommodate the movement of the block 6, and facilitate the block 6 to limit the slide groove 9.
[0026] Reference Figure 1 - Figure 3The sealing assembly includes a sealing ring 15, which is sleeved on the outer periphery of the roller 1, and the outer periphery of the sealing ring 15 is slidably connected to the inside of the mounting seat 2. Clamping assemblies are provided on both sides of the sealing ring 15, and the clamping assembly includes an arc-shaped bracket 14, which is slidably connected to the inside of the mounting seat 2, one end of the arc-shaped bracket 14 is fixedly connected to a pull rod 11, the middle part of the pull rod 11 is fixedly connected to a limiting plate 13, one side of the limiting plate 13 is fixedly connected to a spring 12, the inside of the arc-shaped bracket 14 abuts against the outer periphery of the sealing ring 15, a limiting groove 16 is provided inside the mounting seat 2, the limiting plate 13 is slidably connected to the inside of the limiting groove 16, a movable groove 17 is provided inside the mounting seat 2, the arc-shaped bracket 14 is slidably connected to the inside of the movable groove 17, and the end of the pull rod 11 away from the arc-shaped bracket 14 is fixedly connected to a pull plate 10.
[0027] Specifically, the arc bracket 14 is used to provide a second layer of sealing to prevent impurities from entering the rolling roller. The arc bracket 14 is used to clamp the sealing ring 15. When the arc bracket 14 applies pressure to the sealing ring 15, the sealing ring 15 will be close to the outer periphery of the rotating roller 1. The pull rod 11 is used to facilitate the movement of the arc bracket 14. The pull plate 10 is used to facilitate the movement of the pull rod 11. The spring 12 is used to provide elastic support. The limit plate 13 is used to squeeze the spring 12 to compress the spring 12. The limit groove 16 is used to accommodate the sliding of the limit plate 13. The movable groove 17 is used to accommodate the sliding of the arc bracket 14.
[0028] Working principle: After the arc bracket 14 is sleeved on one end of the roller 1, the roller 1 is installed inside the mounting seat 2. When the roller 1 enters the mounting seat 2, the pull plates 10 on both sides are pulled to make the pull rod 11 drive the arc bracket 14 to move. When the pull rod 11 moves, the limit plate 13 in the middle will squeeze the spring 12, and then the roller 1 is placed in the mounting seat 2. After reaching the installation position, the pull plate 10 is released, and the spring 12 loses pressure and can be reset to generate thrust to push the limit plate 13 to move. When the limit plate 13 moves, it will drive the pull rod 11 to move together, and then the arc bracket 14 moves toward the tightening sealing ring 15, and then the inside of the sealing ring 15 is tightly abutted against the outer periphery of the roller 1, thereby achieving an efficient sealing environment.
[0029] Secondly, by moving the levers 4 on both sides of the mounting seat 2 toward each other, the two levers 4 drive the cross bar 5 to move. When the two cross bars 5 move, they will move along the support rod 7 to squeeze the compression spring 8, and then the sealing baffle 3 will be installed on one side of the mounting seat 2. After the block 6 enters the slide groove 9, the lever 4 can be released, and the compression spring 8 can generate thrust to reset after losing pressure, pushing the cross bar 5 to move, so that the block 6 slides into the interior of the sealing baffle 3, forming a limit for the sealing baffle 3, thereby forming a first layer of protection for the external medium through the sealing baffle 3, and forming a first layer of seal for the rotating roller 1.
[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
