The vacuum aluminizing system is characterized in that a set of flexible printing mechanism is additionally mounted on a process roller of a vacuum aluminizing machine, and comprises a vacuum aluminizing machine sealed chamber, wherein an oil tank, a transferring roller and a printing roller are arranged in the vacuum aluminizing machine sealed chamber; silicone oil is held in the oil tank; the transferring roller is arranged above the oil tank; the printing roller is arranged on one side of the transferring roller; a rubber sleeve with anti-fake patterns engraved on the surface is sleeved on the periphery of the printing roller; the transferring roller and the printing roller are in contact fit, and a scraper is arranged in front of the transferring roller and the printing roller; the exterior of the printing roller of the sealed chamber is near an aluminizing process roller; and the aluminizing process roller and the printing roller are in contact fit, and the circumferences of the aluminizing process roller and the printing roller are provided with substrates. The aluminized layer with anti-fake identification printing patterns is formed by combining the basic principle and method of flexography and vacuum aluminizing technology; and the anti-fake identification has the advantages of distinct layers, obvious darkness and light, vivid image, massive metal texture, and excellent anti-fake effect, so that the anti-fake identification is difficult to be simulated.

Description

A kind of vacuum aluminum-coated system

Technical field

The utility model relates to a kind of vacuum aluminum-coated system, belongs to vacuum aluminum-coated systems technology field.

Background technology

At present, the vacuum aluminium-plated paper of known band anti-counterfeiting mark adopts the explained hereafter of band holographic false proof pattern more, and its typical process flow is divided into two kinds of straight plating method and transfer methods.

One) direct Alplate method:

1. mold pressing on the OPP film forms the OPP film of being with holographic anti-counterfeiting label;

2. will be compound with the OPP film and the paper base material of holographic anti-counterfeiting label;

3. will peel off with the OPP film and the paper base material of holographic anti-counterfeiting label, holographic anti-counterfeiting label is transferred on the paper base material;

4. on paper base material, aluminize;

5. on aluminium coated, be coated with aluminium protective layer (band colouring).

Two) transfer aluminum plated method:

1. coating is fit to mold pressing and aluminized coating on the PET film;

2. mold pressing forms holographic anti-counterfeiting label on coating;

3. on the PET film of band holographic anti-counterfeiting label, aluminize;

Aluminized PET film and paper substrate is compound 4.;

5. PET film and paper substrate are peeled off.

No matter directly Alplate method still is transfer aluminum plated method, and its used vacuum aluminum-coated system all can't realize antiforge function at paper surface, and complex procedures, the production cost height, and efficient is low, and the product antiforgerg identification that makes is easy to imitation, and antifalse effect is not ideal enough.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of can access clear layer, show the score bright, lifelike image and have thick and heavy metal-like, have the vacuum aluminum-coated system of the vacuum aluminum-coated product of flexographic printing of the band anti-counterfeiting mark of good antifalse effect secretly, this system has adopted the ultimate principle of flexographic printing and method and vacuum aluminium plating process to combine closely, and structure is simple and direct, operation is compact, production cost is low, efficient is high.

The technical solution adopted in the utility model is as follows:

A kind of vacuum aluminum-coated system, its special character is, have a cover and be installed at vacuum aluminum-coated machine technology roller flexographic printing mechanism before, to reach flexographic printing and the vacuum aluminum-coated purpose that combines, flexographic printing mechanism comprises that inside is provided with fuel tank 1, the vacuum aluminum-coated machine sealing chamber 5 of angle stripper 2 and print roller 4, the silicone oil that circulation is carried is equipped with in fuel tank 1 inside, the top of fuel tank 1 is provided with the angle stripper 2 that contacts with silicone oil, one side of angle stripper 2 is provided with the print roller 4 that is mated transmission, print roller 4 outer race are provided with the rubber coating of surface engraving security pattern, angle stripper 2 contacts the place ahead that cooperates and is provided with and is used for scraper 3 that unnecessary silicone oil on the angle stripper 2 is wiped off with print roller 4, the print roller 4 outside close bottoms of sealing chamber 5 are provided with the aluminum plating process roller 6 of evaporation boat 8, and aluminum plating process roller 6 contacts the periphery that cooperates and has base material 7 with print roller 4;

During transmission, when angle stripper 2 rotates the silicone oil in the fuel tank 1 is taken up, meanwhile, scraper 3 is wiped silicone oil unnecessary on it off, the oil film of angle stripper 2 remainders is transferred on the print roller 4 that is mated transmission, print roller 4 will have the oil film trans-printing of security pattern again to the base material 7 of aluminum plating process roller 6 peripheries, will carry out vacuum aluminum-coated with the base material 7 of oil film pattern again;

The set rubber coatings in described print roller 4 surfaces be can dismounting and change rubber coating.

A kind of vacuum aluminum-coated system of the utility model, structure is simple and direct, operation is compact, production cost is low, efficient is high, adopted the ultimate principle of flexographic printing and method and vacuum aluminium plating process to combine closely, form the aluminium coated of band printed patterns (anti-counterfeiting mark), after subsequent disposal, form the product of band anti-counterfeiting mark, the anti-counterfeiting mark that forms under this method has clear layer, show the score bright, lifelike image and have thick and heavy metal-like secretly, have good antifalse effect, so anti-counterfeiting mark is difficult to imitation.
