Problems solved by technology

[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 problem with the cold ironing device, a large amount of waste products will often appear due to the on-line connection, and affect the speed of the whole machine; due to the on-line work, the rotation speed of the roller needs to Synchronized with the speed of the whole machine, the anodized aluminum is continuously conveyed with the rotation of the roller, and skipping steps cannot be realized, thus causing a lot of waste of anodized aluminum; at the same time, when facing various printed products with different post-press processing, the whole machine after online The process is not flexible and has limitations in terms of process

Abstract

The invention discloses roll paper cold iron printing equipment. The equipment comprises an uncoiling unit, a tension control unit, a gluing unit, a cold iron unit and a coiling unit. An operation method comprises the following steps of: conveying roll paper to a gluing traction roller; transferring an adhesive to a part which is required to be subjected to cold iron on the roll paper; reinforcing the viscosity of the adhesive printed on the roll paper by using a gluing ultraviolet (UV) curing device; releasing temporarily-stored electrochemical aluminum by using an aluminum storage device; remaining the part on which the electrochemical aluminum is contacted with the adhesive on the surface of the roll paper, and integrating the part with the paper; recovering residual electrochemical aluminum after the cold iron by using a foil collecting roller; pulling the electrochemical aluminum between an impression roller and a cold iron printing roller in the direction of the uncoiling unit by using the aluminum storage device to realize the jumping of the electrochemical aluminum, and storing the electrochemical aluminum at the same time; and curing a cold iron part on the roll paper by using a cold iron UV curing device to realize the cold iron process of the whole roll paper. The invention has the advantages that: an independent cold iron unit is used, so that the roll paper is directly subjected to cold iron, and the equipment has a flexible process; and the jumping of the electrochemical aluminum can be realized and controlled, so that the electrochemical aluminum is greatly saved.

Description

(1) Technical field: [0001] The invention is suitable for printing machinery, especially for a printing equipment and working method of roll paper cold ironing 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 probl...
