The utility model provides a roller which can be used for winding diamond wires in the technical field of multi-wire cutting.

The roller comprises a roller body 1, and end covers 2 and protective clothing 3 are arranged at two ends of the roller body 1. The specific structure is as follows.

Roller body 1: the roller body is cylindrical and comprises a first end 101 and a second end 102 which are spaced in the axial direction along the axial direction of the roller body 1; a fixing hole 103 penetrating through the body in the axial direction is formed along the direction from the first end 101 to the second end 102; a rubber roller layer 104 is arranged along the peripheral wall of the body 1, and a wire slot 1041 is arranged on the rubber roller layer 104.

End cap 2: the first end 101 of the body is provided with an end cover through hole 201 which is matched with the position of the fixing hole 103; the spindle may pass through the end cap through hole 201. The radial dimension of the end cover 2 is not easy to be overlarge, and the radial side of the end cover is positioned at the inner side of the wire slot 1041.

The protective tool 3: with reference to fig. 4, the protector is disposed at the second end 102 of the body, and a through hole 301 of the protector is disposed thereon, and is matched with the fixing hole 103 in position; one end of the protective clothing 3 is abutted against the roller glue layer 104, and the other end thereof extends to the outside of the roller body 1. The radial side is located at the outer end of the wire slot 1041.

When the rubber roller is used, the diamond wire is wound along the wire groove 1041 of the rubber roller layer 104, the end cover through hole 201, the roller body fixing hole 103 and the protector through hole 301 are inserted on the rotatable main roller, and the roller rotates along with the rotation of the main roller. The protector 3 restricts the diamond wire from coming off.

Furthermore, in some embodiments of the present invention, the side circumference of the protector 2 is an inclined surface that radially shrinks in the direction from the second end 102 of the roller to the first end 101 of the roller, and the radial side of the side near one end of the rubber roller layer 104 is located at the outer end of the wire slot 1041.

In some embodiments of the utility model, the fastening hole 103 is a tapered hole, the protector 3 is disposed at the large-diameter end of the tapered hole, and the end cap 2 is disposed at the small-diameter end of the tapered hole. Referring to the attached drawings, the first end 101 of the roller main body 1 is a small-aperture end, and the aperture size of the end cover through hole 201 is not smaller than the aperture of the small-aperture end of the tapered hole; the second end 102 of the roller main body is a large-aperture end, the protector 3 is installed at the section, the aperture of the protector through hole 301 is in a step shape, and the aperture of the side close to the second end 102 is equal to the aperture of the end part of the taper hole. The diameter of the hole decreases in steps towards the outside near the second end 102.
