In order to simplify the disclosure of the embodiments of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present utility model. In addition, the embodiments of the present utility model can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0028] In order to better understand the purpose, structure and function of the utility model, the high-strength hydrogenated nitrile rubber roller of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1-5 As shown, the high-strength hydrogenated nitrile rubber roller of the utility model comprises a rubber roller body 1, a second fixing plate 7 is welded at one end of the rubber roller body 1, and by installing the second fixing plate 7, the second fixing plate 7 can provide an installation position for the external threaded rod 8, thereby ensuring the stability of the external threaded rod 8 and being very convenient to use. The external threaded rod 8 is welded on the side of the second fixing plate 7, and the shaft rod 2 is installed inside the rubber roller body 1. The surface of the shaft rod 2 is provided with a first fixing plate 6, and the external threaded rod 8 passes through the first fixing plate 6. A nut 9 is installed on the surface of the external threaded rod 8. By installing the first fixing plate 6 and utilizing the fixation between the first fixing plate 6 and the second fixing plate 7, a reinforcement effect is provided between the rubber roller body 1 and the shaft rod 2, and looseness will not occur, and the strength is high when in use.

[0030] A T-shaped slide groove 12 is provided on the surface of the rubber roller body 1, and a T-shaped slider 11 is clamped inside the T-shaped slide groove 12. The surface of the T-shaped slider 11 is fixedly connected to the outer rubber sleeve 3, and the outer rubber sleeve 3 is sleeved on the rubber roller body 1. A fixing ring 10 is welded at one end of the rubber roller body 1, and a bolt 13 is installed on the side of the fixing ring 10. The other end of the bolt 13 passes through the T-shaped slider 11. By installing the outer rubber sleeve 3, when the high-strength hydrogenated nitrile rubber roller is used for a long time and the surface of the high-strength hydrogenated nitrile rubber roller is worn, the bolt 13 can be directly removed to directly replace the outer rubber sleeve 3 on the surface of the rubber roller body 1. There is no need to perform maintenance on the high-strength hydrogenated nitrile rubber roller, which is very convenient to use.

[0031] The bolts 13 are distributed in a ring shape and penetrate the rubber roller body 1. By installing the bolts 13, the bolts 13 can provide a fixing effect for the outer rubber sleeve 3, thereby ensuring the stability of the outer rubber sleeve 3, and the stability is relatively strong during use.

[0032] A slideway 4 is provided on the surface of the shaft 2, and a slide plate 5 is fixedly connected to the inner wall of the first fixed plate 6. The slide plate 5 is located inside the slideway 4. By providing and installing the slide plate 5 and sliding the slide plate 5 inside the slideway, the first fixed plate 6 can be driven to move. At the same time, the first fixed plate 6 can be limited so that it will not rotate, which is very convenient to use.

[0033] The slideway 4 is in an annular distribution form, the first fixed plate 6 is internally fitted to the shaft rod 2, and the slide plate 5 is in an annular distribution form. Through the distribution form opened by the slideway 4, the slideway 4 provides a stable restriction effect for the slide plate 5, so that the first fixed plate 6 will not rotate, and the stability is strong during use.

[0034] The external threaded rod 8 is distributed in a ring shape, and the nut 9 is distributed in a ring shape. The side of the nut 9 is fitted to the first fixing plate 6. The distribution form of the external threaded rod 8 can provide a more stable fixing effect for the outer rubber sleeve 3 after installation, and the stability is stronger during use.

[0035] The working principle of the high-strength hydrogenated nitrile rubber roller: When using the high-strength hydrogenated nitrile rubber roller, the outer rubber sleeve 3 should be sleeved on the surface of the rubber roller body 1 first. When sleeved, ensure that the T-shaped slider 11 is embedded in the T-shaped slide groove 12, and then move the outer rubber sleeve 3 until one end of the T-shaped slider 11 fits in the T-shaped slide groove 12, and then install the bolt 13 on the side of the fixing ring 10 until the bolt 13 is embedded in the T-shaped slider 11. At this time, the outer rubber sleeve 3 can be fixed to the surface of the rubber roller body 1 by the bolt 13, and then the slide plate 5 is embedded in the slideway 4. At this time, the first fixed plate 6 can be moved until the external threaded rod 8 on the side of the second fixed plate 7 penetrates the first fixed plate 6, and then install the nut 9 on the surface of the external threaded rod 8 until the side of the nut 9 fits against the side of the first fixed plate 6. The fixation between the first fixed plate 6 and the second fixed plate 7 provides a reinforcement effect between the rubber roller body 1 and the shaft rod 2, and there will be no loosening. The strength is high when in use, and then the high-strength hydrogenated nitrile rubber roller can be used. When the high-strength hydrogenated nitrile rubber roller is worn on the surface after long-term use, the bolt 13 can be directly removed, and the outer rubber sleeve 3 can be taken out, and the worn outer rubber sleeve 3 on the surface of the rubber roller body 1 can be directly replaced, and there is no need to perform maintenance on the high-strength hydrogenated nitrile rubber roller, which is very convenient to use.
