Furthermore, the outer wall and the inner wall of the 2 layers of the resin tube layer are provided with sawtooth structures.

Further, the inner surface of the common polyurethane adhesive layer 1 is provided with a wear-resistant coating 4.

Further, the thickness of the wear-resistant coating 4 is 0.1mm-0.3 mm.

Furthermore, the included angle formed by the lines of the outer surface layer of the common polyurethane adhesive layer 1 and the horizontal line is not more than 5 degrees. .

Further, the thickness of the common polyurethane adhesive layer 1 is 1 mm; the thickness of the resin tube layer 2 is 2 mm; the thickness of the polyurethane semiconductor conductive adhesive layer 3 is 5 mm.

Compared with the prior art, the utility model discloses following beneficial effect has at least:

the utility model discloses mainly utilize atmospheric pressure to make the rubber roll sleeve inflation, make it reach strict installation requirement in the installation.

The utility model discloses an outmost polyurethane semiconductor conductive adhesive layer that has set up, the theory is used to the electro-magnet in other words to the principals on static glue film, and its effect is that when the rubber roll when the operation produce static through the electric current and adsorb on the rubber roll with the printing ink that must use between the rubber roll uniformly to make the rubber roll can reach operation requirement when the work.

The resin tube layer of the utility model is used for consolidating the rubber roller, so that the rubber roller can be manufactured more precisely and stably and has the function of a framework, the nonmetal adopted is determined by the characteristic of the rubber roller due to the sleeve, and the centering material has good elasticity, such as toughness, wear resistance and the like, so that the rubber roller can be better matched with a steel core on a machine in a sizing range.

Ordinary glue film of polyurethane on the one hand guarantee that the rubber roll can assemble the main part of steel core, convenient close control size precision, on the other hand plays certain insulating effect, places the electrostatic breakdown.

The utility model discloses still set up wear-resistant coating in the inside of the ordinary glue film of polyurethane, improved the wearability on the one hand, on the other hand improves insulating nature to a certain extent.

The utility model discloses a resin pipe layer surface sets up to the sawtooth structure, because whole shaping adopts the mode of pouring, comparatively rough surface can improve the degree of adhesion between each layer, makes the laminating more firm.

The utility model provides a promote method of novel polyurethane rubber roll installation accuracy, it can avoid the equipment error that produces in the static polyurethane is made, has not only solved the nonconformity of rubber roll in the actual production, has also changed the work efficiency of rubber roll, very big solution the technical problem who exists in the product production.
