Online-peeling rotary intaglio printing apparatus and production process thereof

Abstract

The invention discloses an online-peeling rotary intaglio printing apparatus. The online-peeling rotary intaglio printing apparatus orderly comprises a rotary double-station non-stoppage unwinding device, an introduction device, a peeling unit, a double-station film winder and a set-type rotary intaglio printing unit. The online-peeling rotary intaglio printing apparatus further comprises a secondary adhesive tape mechanism positioned between the dual-station film winder and the set-type rotary intaglio printing unit; the secondary adhesive tape mechanism comprises a rubber covered roller, a doubling steel roller, a doubling roller and a reciprocating mechanism. An on-line peeling rotary intaglio printing method is realized by using the apparatus. Compared with the prior art, the online-peeling rotary intaglio printing apparatus has the advantages that a basal film and a transfer composite paper are directly wound after being composited in the production process to manufacture a transfer composite paper scroll with the basal film; and under the protection of the basal film on the surface of the transfer composite paper, the quality defects about abrasion mark and sticky mark are avoided in the winding process; therefore, the defective index is greatly reduced.

Description

Technical field [0001] The invention relates to a printing device and its production process, more specifically to an on-line peeling rotogravure printing device and its production process. Background technique [0002] As the country's requirements for environmental protection are getting higher and higher, ordinary composite paper is used less and less because of the non-degradable base film on the surface. In order to meet the requirements of environmental protection, the printing industry has turned to transfer composite paper (ie transfer aluminized paper) for printing. [0003] The existing transfer composite paper production process sequentially includes the following steps: coating a release layer on the base film, vacuum plating aluminum on the release layer to form a vacuum aluminum plating layer, and combining the vacuum aluminum plating layer with paper to obtain a base film The transfer composite paper is peeled from the release layer to obtain the transfer composite ...

AI Technical Summary

Problems solved by technology

The transfer composite paper roll is a roll of transfer composite paper after the base film is peeled off. The surface of the transfer composite paper is an aluminum layer (ie vacuum aluminized layer) and a layer of coating (varnish layer) on the surface of a few microns, so The surface of the transfer composite paper is very sensitive to external forces such as friction. During the winding process of the transfer composite paper, under the action of tension generated during winding, the paper layers of the transfer composite paper are always subject to the stress generated by the rewinding process. Make the paper layers rub and squeeze each other, so that the surface of the transfer composite paper is prone to rubbing and sticking defects, and it is difficult for the producer to control the quality of the transfer composite paper surface, often resulting in a lot of waste products
