Abstract

The invention discloses single paper cold waving printing equipment. The equipment comprises a paper feeding unit, a gluing unit, a cold waving unit and a paper collection unit. An operation method of the equipment comprises the following steps of: conveying single paper to the gluing unit through the paper feeding unit; transferring an adhesive onto a part which is required to be subjected to cold waving on the paper, wherein the viscosity of the adhesive printed on the paper is improved by an ultraviolet (UV) curing device I; holding the paper by using a cripper on a cold waving printing roller; discharging electrochemical aluminum which is temporarily stored by using an aluminum storage device; recovering the electrochemical aluminum which remains after the cold waving by using a foil collection roller; pulling the electrochemical aluminum between an impression roller and the cold waving printing roller by using the aluminum storage device towards the paper feeding unit so as to realize the jumping of the electrochemical aluminum, and storing the electrochemical aluminum at the same time; curing a part which is just subjected to the cold waving by using a UV curing device II; and transferring the cured paper by using a chain towards a paper collection pile so as to realize the whole single paper cold waving process. The invention has the advantages that: due to the adoptionof an independent cold waving unit, the single paper is directly subjected to the cold waving, so that the jumping of the electrochemical aluminum can be realized and controlled, and the electrochemical aluminum can be greatly saved.

Description

(1) Technical field:

[0001] The invention is suitable for printing machines, especially for a printing equipment and working method of sheet-fed cold stamping process. (two) background technology:

[0002] In the fierce market competition, in order to increase the added value of products and carry out packaging anti-counterfeiting more effectively, more and more packaged goods adopt hot stamping technology. Compared with the hot stamping technology, the cold stamping technology does not need to use a heated metal printing plate, which saves energy and reduces consumption. Instead, it uses printing adhesives to transfer electrochemical aluminum. The cold stamping speed is fast and the efficiency is high. Therefore, cold stamping technology It is a new technology that meets the needs of the processing market.

[0003] Most of the existing cold ironing devices in the market work on-line with offset printing machines or flexographic printing machines, but when there is a proble...
