Abstract
A gravure ink distributing device changes the conversion from direct ink supply to indirect ink supply by additionally arranging a set of ink distributing rollers, avoids the direct contact of UV ink and a gravure roller, plays a role in protecting the gravure roller, and solves the problem that the UV ink can generate bubbles in quick inking; the utility model discloses a printing process is smooth, and the high-quality finished product of product printing rate is high, and the outward appearance that has beautified the printing product has improved economic benefits.
Description
Technical Field
The invention relates to the field of printing, in particular to a gravure ink distributing device.
Background
Intaglio printing is called gravure for short, is one of four printing modes, intaglio printing is a direct printing method, and ink contained in intaglio pits is directly printed on a printing stock, wherein the gradation of a printed picture is determined by the size and the depth of the pits, if the pits are deeper, more ink is contained, and the ink layer left on a printed matter after being printed is thicker; conversely, if the pit is shallow, the amount of ink contained is small, and the ink layer left on the substrate after the imprint is thin.
But general gravure printing UV printing plate is low in printing resistance, and easy bubble, the easy black scheduling problem that appears getting rid of appears in the printing process, because UV printing ink can produce the bubble in quick inking, after the bubble bursts to split, transfer to the stock and can lead to the printed product to appear the phenomenon of the tiny spot and the leveling difference after the UV gloss oil drying, cause the space of a whole page after the printing unevenness, cause the damage of the space of a whole page, reduced work efficiency for the defective percentage improves, influences economic benefits.
Disclosure of Invention
The present invention is directed to a gravure ink distributing apparatus, which solves the above problems in the prior art.
The technical problem solved by the invention is realized by adopting the following technical scheme: a gravure cross inking apparatus comprising: the printing device comprises a printing cylinder, a gravure plate roller, a doctor blade, an ink distributing roller, a gravure machine ink tank, gravure UV (ultraviolet) ink, a detachable hook and a spring; the inner part of the ink groove of the gravure press is provided with gravure UV printing ink, and a gravure plate roller is arranged above the gravure UV printing ink; and ink distributing rollers are respectively arranged on two sides of the gravure roller.
The ink scraping knife is arranged on the gravure roller, and the impression cylinder is connected with the gravure roller through the ink scraping knife.
And the ink distributing roller is additionally arranged between the gravure roller and the gravure UV ink, and the direct ink supply is changed into the indirect ink supply.
The two ends of the ink distributing roller are provided with springs, so that the contact pressure between the ink distributing roller and the gravure roller can be adjusted, and the height of an ink groove of the gravure press is changed to adjust the ink distributing roller.
The ink distributing roller is connected with the gravure ink groove through the hook, and can be freely detached.
A layer of water velvet sleeve is arranged outside the ink distributing roller, so that the problem of inconsistent gravure speed caused by slippage between the ink distributing roller and a gravure roller is solved.
Compared with the prior art, the invention has the beneficial effects that: the ink distributing roller changes the conversion from direct ink supply to indirect ink supply by additionally arranging the set of ink distributing rollers, avoids the direct contact of UV ink and a gravure roller, plays a role in protecting the gravure roller, and solves the problem that the UV ink can generate bubbles in quick inking; the printing process of the invention is smooth, the printing rate of the product is high, the finished product is high in quality, the appearance of the printed product is beautified, and the economic benefit is improved.

Detailed Description
The conception, specific structure and technical effects of the present invention will be described clearly and completely with reference to the following embodiments and the accompanying drawings, so that the objects, features and effects of the present invention can be fully understood, it is obvious that the described embodiments are only a part of the embodiments of the present invention, and other embodiments obtained by those skilled in the art without any inventive work based on the embodiments of the present invention belong to the protection scope of the present invention, in addition, all the coupling/connection relations designed in the patent are not directly connected with each other, but rather, all the coupling accessories can be added or reduced to form a more coupling structure according to the specific implementation conditions, so that the technical means, the creation features, the purpose and the effects of the present invention can be easily understood, the invention is further illustrated.
As shown, a gravure ink distribution device includes: the printing device comprises a printing cylinder, a gravure plate roller, a doctor blade, an ink distributing roller, a gravure machine ink tank, gravure UV (ultraviolet) ink, a detachable hook and a spring; the inner part of the ink groove of the gravure press is provided with gravure UV printing ink, and a gravure plate roller is arranged above the gravure UV printing ink; and ink distributing rollers are respectively arranged on two sides of the gravure roller.
The ink scraping knife is arranged on the gravure roller, and the impression cylinder is connected with the gravure roller through the ink scraping knife.
And the ink distributing roller is additionally arranged between the gravure roller and the gravure UV ink, and the direct ink supply is changed into the indirect ink supply.
The two ends of the ink distributing roller are provided with springs, so that the contact pressure between the ink distributing roller and the gravure roller can be adjusted, and the height of an ink groove of the gravure press is changed to adjust the ink distributing roller.
The ink distributing roller is connected with the gravure ink groove through the hook, and can be freely detached.
The oscillating roller is made of rubber materials with the hardness of 80-85, and the surface is smooth; the ink distributing roller is easy to slip after contacting with the gravure plate roller, so that the speeds of the ink distributing roller and the printing plate are asynchronous, the friction with the gravure plate roller is serious, and the printing durability of the printing plate is reduced; in order to solve the slipping phenomenon, a layer of napping sleeve is added outside the ink distributing roller to increase the friction force of the surface of the ink distributing roller; the water velvet sleeve is composed of the inner vinylon fibers and the outer rayon, the silk threads are arranged more closely, the water absorption performance and the ink adhesion performance are better, the chemical corrosion resistance and the abrasion resistance are better, the ink distributing roller can be tightened, the ink distributing roller is not easy to slip, and the effect of synchronizing the speeds of the gravure roller and the ink distributing roller is achieved.
Compared with the prior art, the invention has the beneficial effects that: the ink distributing roller changes the conversion from direct ink supply to indirect ink supply by additionally arranging the set of ink distributing rollers, avoids the direct contact of UV ink and a gravure roller, plays a role in protecting the gravure roller, and solves the problem that the UV ink can generate bubbles in quick inking; the printing process of the invention is smooth, the printing rate of the product is high, the finished product is high in quality, the appearance of the printed product is beautified, and the economic benefit is improved.
While there have been shown and described what are at present considered to be the fundamental principles of the invention and its essential features and advantages, it will be understood by those skilled in the art that the invention is not limited by the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
