Description
Technical Field

Background
With the development of economy in China, the requirements of high-end printed matters are more and more, and the requirements on the color, the anti-counterfeiting performance and the refinement degree of the packaging printed matters are also more and more. However, for soft packaging materials, in the process of processing the rolled film, because the film material for soft packaging has stronger tensile property, the positioning processing has great difficulty.
The existing soft packing material is generally printed by using a PET (Polyethylene terephthalate) film, because the ductility of the PET film is relatively weak, the difficulty of positioning printing processing is slightly low, and the printing quality is relatively stable. However, PET films have limited applications, are generally used for single-sided printing, and are mainly used for printed matters with small variations on a printing material (such as paper).
In the period of high demand of the printing industry of the journal newspapers, the double-sided processing printing is mainly carried out on paper, the relative tensile property of the paper is limited, and meanwhile, the double-sided processing is mainly aimed at double-sided color image-text printing. In order to show more exquisite effect, the ordinary printing precision can not meet the processing resolution of the grating layer and the image-text layer.
With the progress of printing technology, high-stretch film materials such as BOPP (Biaxially Oriented Polypropylene) are used more and more on soft package printed matters, have high antifogging property and higher refinement degree than PET films, but have certain limitations in aspects of positioning printing, positioning processing (such as film pressing) and the like due to the high biaxial stretchability of the BOPP films.
At present, when the double-sided processing of membrane materials, the membrane materials are generally firstly unreeled, printed and rolled on one side, and then printed on one side of the membrane materials in the same mode, so that the working efficiency is low, and the membrane materials are easily lengthened due to the unreeling and rolling processing modes for multiple times, and the positioning difficulty is increased when the membrane materials are processed.
Thus, the prior art has yet to be improved and enhanced.

Optionally, the molding cursor may be a laser cursor or a laser dumb mark, and only needs to be set on one surface of the stretch film according to the length of the plate pitch, so as to be recognized and read by the electric eye 6. When the electric eye 6 identifies that the overprinting position on the other surface of the stretched film exceeds the registration position, the floating roller unit 4 moves to one side while the film is fed, and the film is synchronously stored to increase the tension of the film fed by the second satellite type printing device 7 until the overprinting position is superposed with the registration position; on the contrary, when the electric eye 6 recognizes that the overprinting position on the other surface of the stretch film does not reach the registration position, the floating roller unit 4 moves to the other side while the film is fed, and the film is synchronously placed to reduce the tension of the film fed by the second satellite printing device 3 until the overprinting position coincides with the registration position.
The number of the transverse rectification rollers 52 is more than two, when the transverse offset generated by the overprinting of the stretch film is detected, the motor 53 controls the transverse deflection frame 51 to swing in the opposite direction of the offset by a preset angle (for example, 5 degrees), so that the transverse rectification rollers 52 synchronously swing, and when the electric eye detects that the overprinting of the mold pressing cursor 10 is accurate in real time, the motor controls the transverse rectification rollers 52 to reset. When resetting, in order to prevent the stretch film from deviating again, the motor 53 controls the transverse rectification roller 52 to descend to a preset height, and after the angle is reset, the transverse rectification roller rises to the preset height.
