[0006] In the above-mentioned guide straightening wheel, the outer wall of the guide straightening outer ring is provided with a guide straightening groove.

[0007] In the above-mentioned guide straightening wheel, sealing grooves are provided on the side surfaces of the guide straightening outer ring and the guide straightening inner ring, and sealing rings are nested inside the two sealing grooves.

[0008] In the above-mentioned guide straightening wheel, a liquid injection hole connected to the retaining frame is opened on the surface of the sealing ring, and a through hole connected to the roller groove is opened on the surface of the retaining frame.

[0009] In the above-mentioned guide straightening wheel, a sealing plug is nested inside the liquid injection hole, and the size of the sealing plug is the same as the inner diameter of the liquid injection hole.

[0010] In the above-mentioned guide straightening wheel, a plurality of assembly grooves are equidistantly formed on the inner wall of the guide straightening inner ring.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the guide straightening wheel can limit the roller through the arc-shaped fixing plate provided on the side wall of the roller groove, ensuring that the roller is not easily squeezed out inside the rolling groove, thereby improving the use stability of the guide straightening wheel; at the same time, an injection hole is provided on the side of the sealing ring, through which the roller inside the rolling groove can be lubricated, thereby reducing the friction between the roller and the guide straightening outer ring and the guide straightening inner ring, thereby improving the service life of the guide straightening wheel.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 The utility model provides a technical solution for the guide straightening wheel:

[0018] according to Figure 1-3 As shown, it includes a guide straightening outer ring 1, a guide straightening inner ring 2, a retaining frame 6 and a plurality of rollers 8. The guide straightening outer ring 1 is sleeved and connected with the guide straightening inner ring 2. The retaining frame 6 is fixedly installed between the guide straightening outer ring 1 and the guide straightening inner ring 2. A plurality of roller grooves are equidistantly provided on the surface of the retaining frame 6. The inner walls of the plurality of roller grooves are fixedly installed with arc-shaped fixing plates 7. The interiors of the plurality of roller grooves are rollingly connected with rollers 8. The inner wall of the guide straightening outer ring 1 and the outer wall of the guide straightening inner ring 2 are provided with rolling grooves 9.
