Description

Printing machine with ironing roller

The invention relates to a printing machine with a cold ironing roller, and is a printing machine structure used for printing and cold ironing.

Printed materials such as books, newspapers and magazines, literature, posters, and various product packaging are widely circulated in the market. In addition to being used as document records and information dissemination, as the times progress, people pay more attention to visual beauty, and printed materials are used more for publicity. Or decorative packaging purposes, and the mature printing technology has also derived a variety of different types of printing, among which cold foil printing with metallic texture is very popular.

Please refer to Figure 1, which is a printing machine 1 of the current conventional technology. There are a plurality of rollers 11 for printing operations installed inside. Each roller 11 brings ink into the aluminum plate of the special cold stamping groove for lithographic printing when rolling. , and then print the ink in the aluminum plate on the rubber wheel, and then transfer it to the paper (or other printed materials). A cold-foil embossing roller 13, next to the cold-foil embossing roller 13, a transmission wheel set 131 is arranged. On the printing roller 13, the transmission roller 12, the cold stamping film embossing roller 13 and the transmission wheel set 131 are synchronously rolling during operation. When the paper is brought between the transmission roller 12 and the cold foil embossing roller 13, The original printed position on the paper will stick the part in contact with the cold foil 14 to complete the cold stamping process; in addition to the rollers 11 used for the original printing, the commonly used printing machine 1 is used for cold stamping. The additional installation of the drive roller 12, the cold stamping film embossing roller 13 and the drive wheel set 131 will cause the overall volume of the printing machine 1 to increase and the purchase cost to increase, especially in large factories, many of these must be purchased at the same time. The printing machine 1 performs printing operations. If the volume of the printing machine 1 is too large, the number of the printing machines 1 accommodated in the factory will be reduced, further reducing the overall printing production volume; The cold stamping film embossing roller 13 and the drive wheel set 131 are all rolling synchronously. Therefore, after the cold stamping process, part of the cold foil 14 that is not used will still recover with the rotation of the drive wheel set 131. Please refer to the second In the figure, the figure is the expanded view of the surface that the transmission roller 12 and the cold stamping film embossing roller 13 are in contact with when rolling. The transmission roller 12 and the cold stamping film embossing roller 13 are arranged side by side to present the corresponding position of contact. , wherein, the first length L1 is the total length of the cold perm film embossing roller 13 circumference (that is, the length representing one revolution), the first area A is the effective range of the cold perm film 14 used for cold perm, and the second area B It is the invalid range where the cold foil 14 is not used for cold foil, so every time the cold foil embossing roller 13 rotates the distance of the first length L1, the cold foil 14 has a range beyond the second area B that is not used If the first area A used is smaller, the second area B will be larger, and the waste in the use of the cold film 14 will be more, which will cause a considerable increase in cost or use of company resources in the long run. burden.

Therefore, the cold foil embossing roller and the transmission wheel are combined into a single component, and an independent drive element is provided to drive the cold foil, so as to avoid waste caused by the cold foil stamping roller continuously operating and outputting the cold foil, and at the same time reduce the overall Space, so is the solution of the cold perm film roller structure of the present invention.
