Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-3, a replaceable roller comprises a main structure body, the main structure body includes a roller main body 1 and a roller sleeve 2 sleeved on the outer peripheral surface of the roller main body 1, the outer peripheral surface of the roller sleeve 2 is provided with diamond-shaped wear-resistant patterns, the main structure body further includes limiting rings 3 respectively arranged on two sides of the roller sleeve 2, the two limiting rings 3 simultaneously limit the axial displacement of the roller sleeve 2 to prevent the position deviation of the roller sleeve 2, the outer peripheral surface of the roller main body 1 is provided with at least one clamping groove 13, the inner peripheral surface of the roller sleeve 2 is provided with at least one locking block 21, the locking block 21 is clamped with the clamping groove 13, the locking block 21 and the clamping groove 13 are mutually matched to realize the limiting function of the roller sleeve 2 and the roller main body 1, so as to ensure the roller sleeve 2 and the roller main body 1 to coaxially rotate, the limiting rings 3 are provided with at least one, the roller main body 1 is provided with a threaded hole 11 communicated with the locking hole 31, and the limiting ring 3 and the roller main body 1 are locked through screws.

The thickness of the limiting ring 3 is equal to that of the roller sleeve 2.

The locking block 21 is fixedly connected with the roller sleeve 2 through a bolt.
