Description
Technical Field
The invention relates to the technical field of printing equipment, in particular to a gravure printing line connection concave-convex device and a using method thereof.
Background
Embossing is an important process in post-press working procedures, and is an embossing method without printing ink. The embossing process is used for post-printing processing of printed matters (such as trademark paper, cigarette packets, paper boxes, greeting cards, bottle labels and the like), can enable the printed matters to obtain vivid and beautiful stereoscopic impression, and increases the layering of printed patterns. The embossing mechanism comprises a concave template (such as a concave plate roller) and a convex template (such as a convex plate roller), wherein the patterns of the concave template (such as the concave plate roller) and the convex template (such as the convex plate roller) are in a positive-negative correspondence, and the printing stock is placed between the concave template and the convex template during embossing to extrude the relief-shaped concave-convex patterns by applying larger pressure. Embossing is carried out after gravure printing of a printed matter, and the method is a common printed matter processing mode at present.
Some existing intaglio printing presses often perform single-side pressure application, and a reverse spring disc is arranged between the intaglio rollers to realize roller reset work, but the single-side pressure application causes unbalanced pressing pressure and separation pressure, so that poor synchronism of the relief work of the intaglio rollers is easy to generate, and the effective performance of the relief work is not facilitated, for example, a gravure online embossing workstation with application number 201420843859.4 discloses that "the lower interlocking gear 6 is arranged at the right end of the lower concave table shaft 4, the lower interlocking gear 6 is meshed with the upper interlocking gear 5, and the upper interlocking gear 5 is arranged at the right end of the upper concave table shaft 3; the upper interlocking gear 5 is fixed on the upper sliding block 9, the lower interlocking gear 6 is fixed on the lower sliding block 10, and a reverse spring disc 11 is arranged between the upper sliding block 9 and the lower sliding block 10; when the upper concave table shaft 3 and the lower concave table shaft 4 are pressed and separated, the upper concave table shaft 3 is pressed down by air pressure directly by using an upper pressing device of the embossing roller during pressing, and when the pressure is relieved, the elastic force of the rebound spring disc 11 can bounce the upper concave table shaft 3, so that the separation function is achieved. The technical scheme of the invention has the technical problem of poor synchronization of the relief printing roller due to the typical case of single-side pressure application.
