And then the middle filling layer is arranged in the sleeve to achieve the supporting effect so as to meet the requirement of being applied to flexographic printing. For example, patent publication number CN105500896B discloses a multi-layer composite sleeve, which has a cylindrical structure and a circular cross section; the outer layer is thermoplastic material or hard rubber, the filling layer is polyurethane or rubber hard foaming layer, the skeleton layer and the inner skeleton layer are made of glass fiber resin, and the buffer layer is soft rubber or polyurethane foaming sponge. The multi-layer composite sleeve is characterized in that the inner framework layer and the framework layer are made of glass fiber resin, so that the sleeve is endowed with certain elasticity, is convenient to assemble with an air inflation mandrel, has small mass and high strength, and is safe and reliable in high-speed printing; in the scheme, a multi-layer composite structure is adopted, and the characteristics of the high polymer materials are utilized and exerted, so that the flexography operation is completed by tightly matching with the inflatable mandrel.

The existing support layer of the plate pasting sleeve is formed by rotationally casting double-component polyurethane foam on a pipe, and also is formed by high-temperature vulcanization after rubber coating on the pipe, and is formed by coating a honeycomb plate on the pipe. The polyurethane foam is used as the middle supporting layer, the investment of production equipment is large, the energy consumption in the production process is high, the occupied area of the production line is large, and the production method is limited to the foaming foam rotary casting molding process, so that the selectivity of other materials is limited.
