[0002] In the production of protective paper, it is easy for the protective paper to wrinkle in the conveying roller, which greatly affects the production speed and product quality. Utility Model Content

[0003] The utility model provides a conveying roller structure, comprising a central roller. The surface of the central roller is provided with a plurality of circumferentially arranged surface layers, the surface layers form wood layers or bamboo board layers, the surface layers are screwed together with the central roller, and the surface of the surface layers forms an arc.

[0004] In one or more embodiments, a plurality of mounting holes are provided on the surface layer, a plurality of connecting screw holes are provided on the center roller, and connecting screws are provided on the mounting holes, and the connecting screws are connected to the connecting screw holes.

[0005] In one or more embodiments, the mounting hole forms a countersunk hole, and when the connecting screw is installed in the mounting hole, the top end of the connecting screw is lower than the surface of the mounting hole.

[0006] In one or more embodiments, the left and right sides of the center roller are provided with upwardly protruding steps, and the left and right sides of the surface layer are provided with recessed portions matching with the steps.

[0007] In one or more embodiments, the surface layers are arranged at intervals.

[0008] In one or more embodiments, the center roller is a steel roller.

[0009] The beneficial effects of the utility model are as follows: in the production of protective paper, a conveying roller with a wood layer or a bamboo board layer as a surface layer is provided; since the wood layer and the bamboo board layer have fibers, the protective paper can be stretched out after passing through the surface layer, thus avoiding the generation of wrinkles and solving the problem of generating wrinkles; and since the wood layer or the bamboo board layer has little deformation and high stability after working for a long time.

[0012] The present application scheme is further described as follows in conjunction with the accompanying drawings:

[0013] See attached Figure 1-2A conveying roller structure includes a center roller 1, wherein the surface of the center roller 1 is provided with a plurality of circumferentially arranged surface layers 2, wherein the surface layers 2 form wood layers or bamboo board layers, and the surface layers 2 are screwed together with the center roller 1, and the surface of the surface layers 2 forms an arc.

[0014] Furthermore, a plurality of mounting holes 21 are provided on the surface layer 2 , a plurality of connecting screw holes 11 are provided on the center roller 1 , and connecting screws 22 are provided on the mounting holes 1 , and the connecting screws 22 are connected to the connecting screw holes 11 .

[0015] Furthermore, the mounting hole 21 forms a countersunk hole, and when the connecting screw 22 is installed in the mounting hole 21, the top of the connecting screw 22 is lower than the surface of the mounting hole 21 to avoid the connecting screw 22 protruding from the surface layer, thereby preventing the connecting screw 22 from affecting the production of the protective paper.

[0016] Furthermore, the left and right sides of the center roller 1 are provided with upwardly protruding steps 12 , and the left and right sides of the surface layer 2 are provided with recessed portions 23 that match the steps 12 .

[0017] Furthermore, the surface layers 2 are arranged at intervals to reserve deformation space, and the surface of the surface layer 2 forms an arc shape.

[0018] Furthermore, the center roller 1 is a steel roller body.
