Laser hologram image is seamless roller UV marking press
Technical field
The utility model relates to a kind of laser hologram image marking press, especially relates to the seamless roller UV of a kind of laser hologram image marking press.
Background technology
At present, all in the world laser hologram image marking presses are broadly divided into two types: 1. high temperature, the high pressure of the plastic sheeting of precoating imaging layer (coil paper) are embossed into picture.2. laser hologram image UV is embossed into picture (being embossed into picture while being coated with).
The machine that in first kind of situation, is divided into dual mode usually: the one, press machine, its advantage is to impress PET, PVC etc. are harder, thicker material, its impression width is no more than 1000mm.Roll modus operandi and two according to the difference classification three of press machine structure and roll modus operandi.Three advantages of rolling are that the intermediate plate in rolling by three rolls, the cam adjustment on both sides, imprinted pattern as the time can realize that the coincidence of image connects.Two roll the modus operandi imprinted pattern looks like to have a finedraw.The outstanding advantage of the soft press of wide cut is that the impression breadth is wideer than press machine, and maximum can reach 1000mm.The material of main impression is a Bopp laser class film, and the thickness of film approximately is 0.002~0.003mm, it be two roll modus operandi, the laser hologram image working plate sticks on the higher steel rider of smooth finish with double faced adhesive tape.Pressure roll is the high-temperature resistant rubber roller, and the bright steel rider that has refrigerating function with an inside contacts pressure rubber roller, during work, supplies with its pressure and instant cooling rubber rollers.The laser hologram image working plate of press machine is to roll on the fixing middle steel of steel anchor clamps, does not need two-sided gluing.Above machine has common shortcoming: 1. imprinted pattern looks like that seam is arranged, 2. high temperature (100 ℃~150 ℃), and high pressure (0.5 MPa), power consumption is big, generally needs 20~30kW, if it is then bigger to count the power consumption of precoating imaging layer in.The power consumption 100kW of general coating machine.3. by reason of heavy pressure, the temperature height adopts cooling method to being embossed into the plastic sheeting typing after looking like during machine works.Tension force after the bad and rolling of the flatness of plastic sheeting is bad like this, influences the manufacturability and the usability in road thereafter.
Laser hologram image UV marking press is researched and developed the novel machine of release in order to overcome above-mentioned a part of shortcoming.It is earlier with UV paint for imaging coating straticulation, and with the roller that has the laser hologram image plate or with transparent plastic film that has laser hologram image and the imaging of UV coating contact printing, separation forms.The shortcoming of the method is to have seam, coating to be embossed into as thicker, plastic sheeting to become crisp and hard, is unfavorable for the manufacturability and the usability in road thereafter.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of seamless roller UV of laser hologram image marking press of having realized being embossed under seamless and the normal temperature picture.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of laser hologram image is seamless roller UV marking press, comprise and unreeling, the right-hand feeding deflector roll that is provided with that is unreeling, the right-hand guide roller that is provided with of feeding deflector roll, the most right-handly be provided with rolling, between described feeding deflector roll and guide roller, be provided with the seamless roller of laser hologram image, above the seamless roller of laser hologram image, be provided with the UV cold light source, below the seamless roller of laser hologram image, be provided with coating.
In order to make the power of dragging constant, described unreel and the feeding deflector roll between be provided with the automatic constant tension sensor; Between described guide roller and rolling, be provided with the automatic constant tension sensor.
In order to remove the static on the material, between described automatic constant tension sensor and rolling, be provided with X eliminator.
In order to guarantee the quality of finished product, between described X eliminator and rolling, be provided with optical real-time detection device.
Adopt after the above-mentioned structure, be embossed into picture at normal temperatures, the total energy consumption 9kW of machine, and the total energy consumption of traditional mode of production reaches 30kW energy-conservationly reaches 70%.Because imaging under the normal temperature, base material (plastic sheeting) is distortion not, and the brightness of image improves 25%.Same pattern is seamless be embossed into the picture after, can arbitrarily divide the work to send out into various sizes, cut the waste, enhance productivity.

Embodiment
The seamless roller UV of a kind of laser hologram image shown in Figure 1 marking press, comprise and unreel 109, be provided with feeding deflector roll 115 at the rear that unreels 109, the feeding deflector roll 115 right-hand guide rollers 135 that are provided with, the most right-handly be provided with rolling 150, between described feeding deflector roll 115 and guide roller 135, be provided with the seamless roller 105 of laser hologram image, above the seamless roller 105 of laser hologram image, be provided with UV cold light source 120, below the seamless roller 105 of laser hologram image, be provided with coating 100.
Seamless stamping technique is meant that impression does not produce concealed wire in producing.The method that realizes is that to choose anti-wear performance good, the cylinder of high brightness and high rigidity (circle roller) face, on its face of cylinder, coat photoresists equably, at photoresists photographs laser hologram image, with high fidelity be replicated on the external cylindrical surface of steel rider after the embossment laser hologram image on the photoresists modulation with etching method, because the external cylindrical surface of laser hologram image and steel rider is an one, rather than clamping or stick-on, therefore in producing, impression just can not produce concealed wire.The seamless roll-in of same image can arbitrarily be cut after being printed as picture as requested, does not have the open and close machine waste material of edging surplus and replacing cylinder, reduces raw-material consumption 10%.
Select the deflector roll guiding plastic sheeting contact of a smooth surface for use and by the seamless roller of laser hologram image (the retractable system of plastic sheeting should be automatic constant tension control, to guarantee that plastic sheeting steadily, move glossily).Adjust and configure the parameters such as direct of travel, speed, tension force, coating thickness of plastic sheeting, add the UV coating for preparing in advance.Along with the normal operation of machine, UV coating will be coated between seamless roller of laser hologram image and the film equably.At this moment use UV radiation of light source plastic sheeting in place,, separate with the seamless roller of laser hologram immediately after the curing with UV curing coating.Laser hologram image quilt on the seamless like this roller with high fidelity imprinting and copying is finished by detecting the light rolling on plastic sheeting at last.
This product does not need high temperature, is because the curable imaging layer of UV is coated between seamless roller and the plastic-based film at normal temperatures, peels off with the UV radiation curing simultaneously and impresses out laser hologram image.UV is a cold light source, does not produce heat radiation.Overcome conventional art high temperature, high pressure, the shortcoming that power consumption is big, energy-conservation more than 70%.And automatic tension control, automatic detection alarm are arranged, multiple base materials such as applicable PET, Bopp, PVC, PE, coil paper.
