The utility model proposes a kind of forging printing plate rollers 31, are applied to moulding press 100.
As shown in Figures 1 to 3, in 31 1 embodiment of the utility model forging printing plate roller, forging printing plate roller 31 include roller 311,
It is molded mother matrix 312, hot oil pipe 313, mother matrix volume 312 of molding is affixed on the outer peripheral surface of roller 311, and roller 311 is equipped with heating oil duct
311a, hot oil pipe 313 passes through one end of roller 311 and protrudes into heating oil duct 311a, and the inserting end of hot oil pipe 313 is connected to
The other end of roller 311, the tube wall that hot oil pipe 313 is located in heating oil duct 311a offer several oilholes 3131, adjacent two oil
The spacing in hole 3131 is gradually reduced along flow of hot direction.
Specifically, roller 311 is substantially cylindrical, internal to form heating oil duct 311a；Molding mother matrix 312 post in
The peripheral surface of roller 311, molding mother matrix 312 are generally the metallic nickel version with holographic laser image, and thickness is generally 15-
80μm.The heating of forging printing plate roller 31 generallys use oil heating roller 311, and hot oil is provided by oil heater, and via hot oil pipe 313
It is delivered in heating oil duct 311a.It should be understood that one end of hot oil pipe 313 is connected to oil heater, the other end protrudes into heating oil
In road 311a, and its end abutment, in the other end of roller 311, the tube wall of the hot oil pipe 313 protruded into heating oil duct 311a is opened
Equipped with several oilholes 3131, so that the hot oil in hot oil pipe 313 is flowed in heating oil duct 311a by oilhole 3131, pair roller barrel
311 are heated.Further, the spacing of adjacent two oilhole 3131 is gradually reduced along flow of hot direction, is so arranged, by
It is gradually decreased in its temperature with flow of hot, by gradually decreasing the spacing of adjacent two oilhole 3131, may make 311 edge of roller
The Temperature Distribution in flow of hot direction is relatively uniform.When coated film by the forging printing plate roller 31 that is heated by when, due to roller
The temperature on 311 surfaces of cylinder is along its axial distribution uniform, then the phenomenon that being not in film version easy to stick, while can also improve holography
The brightness uniformity of film, to guarantee the clarity of hologram pattern.
Accordingly, it is to be understood that, the technical solution of the utility model, forging printing plate roller 31 is affixed on roller including roller 311, volume
