[0020] like Figures 1 to 7 As shown, the present invention provides a double-disc sealing device for an upper roller of a drafting device, comprising a roller body 1; The insert shaft 2 is arranged on both sides of the roller body 1; The drafting assembly is arranged on both sides of the roller body 1 and the outer surface of the insertion shaft 2, and can be used to draft and straighten the strips on the surface by rotating it and the roller body 1 as a whole; A shielding component is arranged at the upper and lower parts of the inner side of the drafting component; The adjusting mechanism includes an adjusting component, a sliding component, a power component, and a linkage component; The adjusting assembly includes a first tooth plate 4, which is arranged above and below the insertion shaft 2, and a second tooth plate 5 is movably installed on the inner wall of the drafting assembly above and below the first tooth plate 4. When the second tooth plate 5 is facing and in contact with the first tooth plate 4, the drafting assembly can be fixed on both sides of the roller body 1.
[0021] By compressing the first spring 9, the slider 7 and the second tooth plate 5 are pushed toward each other and fit with the first tooth plate 4. Since the top of the first tooth plate 4 is meshed with the bottom of the second tooth plate 5, the sealing disk 3 can be fixed on both sides of the roller body 1 and the outside of the plug-in shaft 2, and can also be adjusted through it.
[0022] like Figures 1 to 3 As shown, the drafting assembly includes a sealing disk 3; The sealing disks 3 are movably mounted on both sides of the roller body 1 and the outer surface of the insertion shaft 2. There are two sealing disks 3, and the two sealing disks 3 have the same size.
[0023] The above solution is adopted: by providing the sealing disk 3, when the two sealing disks 3 are fixed on both sides of the roller body 1, not only the two sides of the roller body 1 can be sealed, but also the sliver can be stretched.
[0024] like Figure 7 As shown, a sealing ring 24 is also included; The sealing ring 24 is arranged on the inner wall of the sealing disk 3 , and the outer shape of the sealing ring 24 is annular.
[0025] By adopting the above solution, the sealing effect of the installation connection position of the roller body 1 and the sealing disk 3 can be improved by providing the sealing ring 24 and designing the two sealing rings 24 .
[0026] like Figure 4 As shown, the sliding assembly includes a slide groove 6 and a slider 7; The slide groove 6 is formed on the inner wall of the sealing disk 3 and on both sides of the second tooth plate 5 , and the sliders 7 are disposed on both sides of the second tooth plate 5 and on the inner wall of the slide groove 6 .
[0027] The above solution is adopted: by providing the slide groove 6 and the slider 7, the design of the slide groove 6 and the slider 7 will have a good limiting effect on the overall movement of the second tooth plate 5.
[0028] like Figure 4 As shown, the power assembly includes a limit rod 8 and a first spring 9; The limiting rod 8 is arranged on the inner wall of the slide groove 6 and is movably connected with the inner wall of the slider 7 . The first spring 9 is arranged between the top of the slider 7 and the inner wall of the slide groove 6 and on the outer side of the limiting rod 8 .
[0029] The above solution is adopted: by providing the first spring 9, since the first spring 9 is in a compressed state, it will push the slider 7 to drive the second tooth plate 5 to move downward as a whole.
[0030] like Figure 4 As shown, the linkage assembly includes a movable rod 10, a connecting plate 11, a fixing frame 12 and a fixing shaft 13; The fixed frame 12 is arranged at the front and rear of the inner end of the outer side of the second tooth plate 5, the movable rod 10 is movably connected to the outer side of the inner wall of the sealing disk 3 and the inner end passes through the sealing disk 3, the connecting plate 11 is hinged to the outer end of the inner side of the movable rod 10 and the inner end extends to the fixed frame 12, and the fixed shaft 13 is arranged on the inner wall of the bottom end of the connecting plate 11 and the front and rear ends extend to the inner wall of the fixed frame 12.
[0031] By adopting the above solution, by providing the fixed shaft 13, when the operator pushes the movable rod 10 away from each other, the connecting plate 11 can be deflected, so that the fixed shaft 13 pulls the fixed frame 12 and the second tooth plate 5 to move away from each other as a whole.
[0032] like Figure 7 As shown, the shielding assembly includes a magnet 14 and a shielding cover 25; The shielding cover 25 is hinged to the upper and lower parts of the inner side of the sealing disk 3 and the outer side of the movable rod 10 , and the magnet 14 is arranged on the inner wall of the sealing disk 3 and the middle part of the outer front end of the shielding cover 25 .
[0033] The above solution is adopted: by providing the magnet 14, since the shielding cover 25 is made of iron, there will be an attraction force between the magnet 14, so that the shielding cover 25 can be fixed on the outside of the movable rod 10 for shielding and avoiding accidental contact.
[0034] like Figure 2 As shown, a buffer mechanism is also included, and the buffer mechanism includes a buffer component, a limit component and a drive component; The buffer assembly includes a buffer block 15 and a rubber pad 16; The buffer block 15 is movably mounted on the inner wall of the outer side of the plug shaft 2 , and the rubber pad 16 is arranged on the outer side of the buffer block 15 and the inner wall of the sealing disk 3 .
[0035] The above solution is adopted: by providing the rubber pad 16 , due to the design of the rubber pad 16 , it is possible to prevent the buffer block 15 from moving in opposite directions and causing damage to the inner wall of the sealing disk 3 .
[0036] like Figure 6 As shown, the limiting assembly includes a limiting groove 17 and a limiting block 18; The limiting groove 17 is formed on the inner wall of the insertion shaft 2 and above and below the buffer block 15 , and the limiting block 18 is disposed on the inner side of the above and below the buffer block 15 and on the inner wall of the limiting groove 17 .
[0037] The above solution is adopted: by providing the limiting groove 17 and the limiting block 18, the limiting groove 17 and the limiting block 18 cooperate with each other, so that the overall movement of the buffer block 15 toward and away from each other can be limited.
[0038] like Figure 6 As shown, the driving assembly includes a fixed rod 19, a buffer plate 20, a fixed arc block 21, a fixed block 22 and a second spring 23; The fixing rod 19 is arranged on the upper and lower parts of the inner wall of the plug shaft 2 and the inner side of the buffer block 15, the buffer plate 20 is movably sleeved on the outer surface of the fixing rod 19, the fixing arc block 21 is arranged on the outer side of the middle part of the outer surface of the fixing rod 19, the fixing block 22 is arranged on the inner wall of the buffer plate 20 and the outer side of the fixing rod 19, and the second spring 23 is arranged between the fixing block 22 and the fixed arc block 21.
[0039] The above solution is adopted: by providing the second spring 23, since the second spring 23 is in a compressed state, it will push the fixing block 22 to drive the buffer plate 20 to deflect, so as to push the buffer block 15 back to perform auxiliary adjustment processing.
[0040] The working principle and use process of the present invention: First, when the operator needs to adjust the overall length of the roller body 1 and the sealing disk 3 as required, the shielding cover 25 can be flipped open first, and then the movable rods 10 at the upper and lower ends can be pressed to move toward each other so that the connecting plate 11 can be deflected, and the fixed shaft 13 will move toward each other along the fixed frame 12, and then the fixed frame 12 and the second tooth plate 5 will be driven to move away from each other as a whole, so that the bottom of the second tooth plate 5 is separated from the top of the first tooth plate 4, and the clamping and fixing effect is released, and finally the sealing disk 3 on both sides of the movement can be adjusted.
[0041] At the same time, due to the elastic force of the second spring 23, the fixed block 22 can be pushed to drive the buffer plate 20 to deflect, and then the buffer block 15 will be pushed to drive the sealing disk 3 to move in opposite directions, thereby assisting the operator to adjust the length, and then adjust it to a fixed position, and then install it on the stretching device for operation. At this time, the second spring 23, the fixed block 22 and the buffer block 15 as a whole can also buffer the stress of the two sealing disks 3 rotating towards each other to reduce vibration and improve the overall service life.
