Problems solved by technology

[0003] The color printing of traditional paper towels is limited to eight colors, and each printing device only provides one printing color, and ordinary flexo printing machines cannot achieve eight-color printing; in addition, paper towels need to be folded and rolled after they are rolled. The cutting process can finally make the finished product. If you want to continue post-printing treatment on the finished paper towel, the requirements for the subsequent process and the difficulty of implementation will be greatly increased.

Embodiment 1

[0052] see figure 1 , a cold stamping process for tissue flexo printing, comprising the following steps:

[0053] S1. Raw paper towel unwinding:

[0054] Using a flexographic printing machine, install the raw paper towel after winding on the paper towel unwinding roller of the flexographic printing machine, adjust the belt so that the outer surface of the belt is in conflict with the original paper towel, turn on the drive motor to drive the belt to convey, and pass the belt The friction between the raw paper towel and the original paper towel can realize the unwinding of the original paper towel, and control the anti-rolling speed of the original paper towel to 100m / min;

[0055] S2. Printing:

[0056] The raw paper towels after unwinding are flexo-printed sequentially through multiple printing devices on the flexographic printing machine, and a pre-printing is performed after the flexo printing is completed, and a layer of pre-printed ink is coated on the surface of the ra...

Embodiment 2

[0068] A cold ironing process for tissue flexo printing, the difference from Example 1 is that the power of the UV lamp in S5 is 210W, and the heating temperature of the oven in S6 is 355°C.

Embodiment 3

[0070] see figure 2 , a cold ironing device for tissue flexo printing, including a frame 1, an unwinding device 2 is arranged on the frame 1, five printing devices 3 are connected to the outlet end of the unwinding device 2, and each printing device 3 is responsible for printing a A pre-printing device 4 is connected to the outlet of the last printing device 3. The difference between the pre-printing device 4 and other printing devices 3 is that the pre-printing ink is used as printing oil. The outlet end of the pre-printing device 4 is connected with a cold ironing mechanism 5, and the outlet end of the cold ironing mechanism 5 is connected with a drying device 6. The drying device 6 includes a plurality of ovens 61 connected in series. In the oven 61, an infrared heating device and a drying device are installed. The outlet end of 6 is connected with paper towel folding device 7. Also be provided with the first driving roller 11 and the second driving roller 12 on the frame...

Abstract

The invention discloses a koldfoil technology and device for flexographic printing of a tissue. The koldfoil technology comprises the steps of uncoiling, printing, preparing of a cold foil stamping film, cold foil stamping, curing of UV adhesive, drying and folding and cutting. The technology is characterized in that flexographic printing and koldfoil are combined, and thus tissue with more than eight colors can be conveniently printed; in addition, pores in the surface of the original tissue can be filled by preprinting before the koldfoil, and meanwhile, a smooth printing film can be formed on the surface of the original tissue, so that the subsequent koldfoil quality can be improved; the original tissue subjected to koldfoil passes through a UV fixing device and then is dried through a subsequent drying oven, so that the UV adhesive can be sped up to cure, and as a result, the color information of a metal foil film can be perfectly transferred to the original tissue to form a combined tissue; and finally, the combined tissue is folded and cut to obtain a finished product. According to the koldfoil technology and device, the steps of the whole technology are simplified, and the difficulty in implementation of the technology can be reduced.

Description

technical field [0001] The invention relates to flexographic printing equipment, in particular to a cold stamping process and device for flexographic printing of paper towels. Background technique [0002] As a daily necessities, paper towels are widely used in restaurants, bathrooms, kitchens and other fields. And in some special occasions such as important banquets, wedding parties, etc., some paper towels with exquisite patterns will be specially made, and the printing of paper towels generally adopts a flexographic printing machine. A kind of flexographic printing machine", including frame, unwinding device, transmission mechanism, printing device, drying tunnel and winding device; said printing device includes a plurality of anilox ink transfer rollers, ink fountain rubber rollers and doctor blades, paper towels After passing through multiple printing devices, the desired pattern is printed, then enters the drying tunnel for drying, and finally winds up. [0003] The ...
