Description
Technical field
The present invention relates to holographic marking press and use the forging printing plate roller field, more particularly, relate to a kind of anisothermal forging printing plate roller.
Technical background
It is that eighties of last century is introduced China from the U.S. latter stage the earliest that the hologram image technology is used on PET plastic coating film.Its principle is as follows: hologram image is by method of taking pictures or photoetching process, image on the photoetching glass coating version, by electrocasting the hologram image on it is copied on the metallic nickel version again, the metallic nickel version that has hologram image that thickness is approximately 15 ~ 80 μ m is fitted on the version roller of hologram image marking press as working version then, the PET coated film is that 140 ℃～200 ℃ version is passed through on the roller in temperature, the limit roller then pressurizes to the PET coated film to the version roller, hologram image on the metallic nickel version is impressed on the PET figure tunic, thereby (false proof) PET plastic sheeting is packed in the holography that is made into rolling.
Current general version roller has conduction oil and imports and exports on the chock plug of version roller one end, this conduction oil is imported and exported and linked to each other with an oil pipe connector.Deep fat is imported and exported by oil pipe connector, conduction oil and is injected into an edition roller inner chamber, makes its temperature rise to mold pressing required temperature and maintenance, and its structure as shown in Figure 1 and Figure 2.
But because the metallic nickel version can produce the interface slit inevitably when the applying of version roller surface, make to extrude the finished film of coming,, and apparent in view black slit or black line occur, influence the application of finished film because version seam place temperature is lower at trade edition roller patrix.
For eliminating the black seam on the finished film, black line or tangible aberration, China's utility model patent " no-plate seam holographic molding device " (patent No.: 200520064521.x) in its summary of the invention, proposed the method for a kind of making " cylindrical seamless molded plate (roller) ", this method will be printed on the planar nickel plate of hologram image, pattern is rolled into cylindric inwardly, and with its mould as electroforming, directly electroforming goes out to be printed on the version roller of hologram image, yet this method makes the production process of version roller become very complicated, the qualification rate and the quality of the version roller of producing also are lower in practice, by as can be known to the analysis of this method, the seamless molded plate roller that the version roller that this method is produced neither be real; (number of patent application: 200510019746.8) disclosing a kind of being used in its summary of the invention is fitted in method on edition roller with holographic nickel plate: with holographic nickel plate winding version roller in Chinese invention patent application " laser holographic molding draw version method ", in the special narrow line of rabbet joint of the length income version roller that the nickel plate is unnecessary, and it is fitted on edition roller nickel plate tension with a voussoir, this method has certain suggesting effect to reducing black seam or black line width, but still can not eliminate defective fully; (patent No.: 200620063831.4) disclose a kind of principle of producing the mold pressing machine of no-plate seam holographic film and being mentioned to this machine in its summary of the invention: the raw material film can be by twice mold pressing in front and back for China's utility model patent " holographic laser molding press machine ", there is a special device to be used for detecting the position of former and later two editions roller version seam, automatically the mode of taking gap not impress when running into the version seam, distance by twice impression station before and after regulating, the zone that twice gap do not impress before and after making is dropped on mutually and has been impressed on the zone that maybe will impress, thereby alleviate of the harmful effect of version seam to finished film, this machine does not carry out technical transformation to existing version roller, and eliminate defective by process control merely, but, because production process is continuous, this machine described " indexing mechanism " can be in the perseveration state, the operating frequency of " indexing mechanism " can become higher and face pressure roller repetitive positioning accuracy problem during high-speed production, pressure roller resetting meeting causes the Strength Changes of exerting pressure, cause the variation of finished film pattern level, simultaneously, adopt and meet the printing process that edition mode that the seam gap does not impress belongs to the color phase step type, the transition of pattern level must be subjected to certain influence, and these factors all can influence the quality of finished film.Problems such as there still do not have perfectly version roller design can solve edition finished film level that seam causes at present to be inhomogeneous, and quality instability, production efficiency are not high.
Summary of the invention
The purpose of this invention is to provide not isothermal contour forging printing plate roller of a kind of working face, use this edition roller that the raw material film is carried out twice mold pressing, can eliminate the finished film quality problems that the version seam causes to greatest extent.
For achieving the above object, the present invention takes following technical scheme:
A kind of contour forging printing plate roller, left chock plug, right chock plug are fixedly connected on edition roller tube wall two ends respectively, and right chock plug has conduction oil to import and export, and this conduction oil is imported and exported and is connected with oil pipe connector.At version roller tube wall a vertical oil duct is arranged; Left side chock plug has cold oil to import and export; Being provided with left chock plug cooling oil duct in left chock plug inside makes edition vertical oil duct of roller tube wall link to each other with the cold oil import and export; This cold oil is imported and exported and is connected with oil pipe connector; Version vertical oil duct of roller tube wall and left chock plug cooling oil duct have been formed cooling oil duct jointly.
The center line of the vertical oil duct of described version roller tube wall parallels with version roller axis.
The axis that described cold oil is imported and exported overlaps with the axis of version roller tube wall.
The length of the vertical oil duct of described version roller tube wall at least be fitted in edition roller on the width of holographic nickel version equate.
Be inserted into an external diameter in the described cooling oil duct less than cooling oil duct internal diameter and the surperficial oil guide pipe that has aperture; This oil guide pipe is inserted to the vertical oil duct end of edition roller tube wall; Described aperture only is distributed in oil guide pipe and is in edition vertical oil duct of roller tube wall one section.
Described version roller tube wall, except that vertical oil duct is arranged, the back oil road that can also have oil return to use, and this two oil duct communicates.
Below operation principle of the present invention is described:
The contour forging printing plate volume is attached on the present invention's the version roller, and the longitudinal oil track pitch on order version seam and the version roller tube wall is from recently.Circulation and Hot Oil Spray is carried out to version roller inner chamber in conduction oil gateway by right chock plug, makes edition roller temperature rise to molding temperature (being generally 140 ℃～200 ℃) and maintenance; Import and export by left chock plug cold oil, cooling oil is circulated in the cooling oil duct of being made up of left chock plug cooling oil duct, the vertical oil duct of version roller tube wall etc., and order version roller is reduced to and can not mold pressing goes out hologram pattern (being generally 60 ℃～120 ℃) in the temperature of the residing outer surface of this vertical oil duct.On the version roller working face the position away from the vertical oil duct of version roller tube wall be highest temperature mold pressing position, the position of the vertical oil duct of the most close version roller tube wall is lowest temperature mold pressing position, because the variation from high temperature to low temperature is continuous, so from highest temperature mold pressing position to lowest temperature mold pressing position, the version roller die extrudes next level effect meeting nature transition, version seam can't appear at after this mold pressing on half-finished some positions significantly, the substitute is that the level depth gradually changes and the imprinted pattern of the appearance that should variations circulates.
Send these semi-finished product to second mold pressing station, the version roller that version roller and the mold pressing of being adopted on this station for the first time used has identical structure and pattern.By adjusting the dance roller system or the deflector roll system of marking press, lowest temperature mold pressing position when the highest temperature mold pressing position in the time of can be with first time mold pressing is adjusted to mold pressing for the second time coincides, like this, the effect of twice mold pressing is carried out complementation, draw the very good holographic moulding film of effect, can eliminate the defect problem that the version seam causes basically.
By above explanation as can be known, the hologram pattern of finished film is the complementation stack of twice mold pressing pattern in fact.Version roller tube wall is cooled off by the part and makes and can not be over-molded on the holographic coated film at the locational version seam of minimum temperature mold pressing, thereby occur " blank ", this chilling temperature is the appearance and the width of influence " blank " directly: cooling is not enough, can occur the mold pressing vestige of version seam on the film; Undercooling, the width of " blank " that occurs on the film is wide, makes the width of normal mold pressing pattern be not enough to additional " blank " width that is somebody's turn to do, and causes the pattern after complementation superposes the uneven situation of level still can occur.Yet, by the synchronous adjustment to the chilling temperature of former and later two editions roller tube wall, the holographic film finished product that can obtain to meet the requirements.
The invention has the beneficial effects as follows: the pattern level transition nature on the coated film after this edition roller die is pressed, the pattern after twice mold pressing is carried out the complementation stack, its finished film is even, the color nature of level visually.
