Problems solved by technology

The plastic film is cumbersome to carry, which often affects the printing efficiency of the film. Moreover, printing holographic patterns on the forward and reverse embossed sides of the plastic film requires high positioning accuracy of the graphics printed on the front and back of the plastic film. The position error of the holographic image embossed on the front and back embossed surfaces of the coating film must be less than 0.01mm. It is difficult to meet the process requirements by using a hot molding machine and a UV molding machine alone for molding.

Embodiment 1

[0035] Take the molded double-sided coated PET film as an example, such as Figure 1-4 As shown, in this embodiment 1, the hot molding system 1 and the UV molding system 2 are used separately, and the UV molding system 2 includes an adjustment system, which includes a positioning adjustment roller 3, a hydraulic cylinder 4, a detection light source 5 and a The detection light source receiving device corresponding to the detection light source 5 ; the hydraulic cylinder 4 is used as a driving device, and its piston rod is connected with the positioning adjustment roller 3 . The detection light source receiving device includes a receiving probe 6 and a computer system, and the receiving probe 6 is data connected to the computer system; the hydraulic cylinder 4 is also connected to the computer system through electronic components.

[0036] The printing layer is coated on the positive embossing side of the PET film. The printing layer is used to increase the adhesion between the ...

Embodiment 2

[0050] The difference between this embodiment 2 and embodiment 1 is that in this embodiment 2, if Figure 5 As shown, the thermal molding system 1 and the UV molding system 2 work in line. Along the traveling direction of the film, a front turning system and a back turning system are respectively arranged upstream and downstream of the thermal embossing system 1, wherein the front turning system consists of a first guide roller 20 and a second guide roller 21, the first guide roller 20 and the second guide roller 21 are arranged successively along the direction of travel of the film, and the first guide roller 20 is between the first version roller 7 and the second version roller 9 and is positioned below the first version roller 7; the second guide roller 21 Between the first version roller 7 and the first guide roller 20 and above the first version roller 7; the back turning system is composed of the third guide roller 22, the fourth guide roller 23 and the fifth guide rolle...

Abstract

The invention discloses a mould pressing method for a double-surface-coated film. According to the mould pressing method, a front UV mould pressing system and a rear UV mould pressing system which are connected in a front-and-rear direction are capable of carrying out mould pressing on a forward impression surface and a backward impression surface of the film by virtue of a front turnover system and a rear turnover system; and accurate alignment for patterns formed on the forward impression surface and the backward impression surface of the film through mould pressing are ensured by virtue of an adjustment system. The mould pressing method disclosed by the invention is accurate in location, carrying for the film during the mould pressing process is not required, and the production efficiency is high; and the film is small in deformation and high in smoothness during a production process, and the produced film can achieve high-quality requirements.

Description

technical field [0001] The invention relates to the technical field of holographic anti-counterfeiting and holographic laser packaging, in particular to a molding method of a double-sided coated film. Background technique [0002] The application of holographic laser image technology on plastic coating films was first introduced from the United States to China at the end of the last century. The principle is as follows: the holographic laser image is imaged on the photolithographic glass coating plate by photographing or photolithography, and then the holographic image on it is copied to the metal nickel plate by electroforming, and then the thickness is about 15~ The 80μm metal nickel plate with holographic laser image is used as the embossing plate and attached to the plate roller of the holographic laser molding machine. The coating film passes on the heated plate with the embossing plate, and the side roll is coated on the plate roller. The first layer of film is pressu...
