Abstract

The invention relates to an improved flexographic printer comprising a structure (11) that supports a printing cylinder (12), on top of which the plate (20) is placed. The upper part of the left-hand side of the inventive printer comprises two diagonally-disposed rollers which are provided with different diameters (15) and between which cardboard or another similar material (30) passes. The lower part of said side comprises three equidistant rollers (14) which are mounted on a part (17) that serves as the centre of rotation for the three anilox or ceramic cylinders (14). Said printer also comprises an ink chamber (18), which is provided with a double-scraper, and a locking cylinder (16). Printing on the corrugated board or similar material (30) is triggered by the rotation of the roller (11) together with the action of the three rollers (14).

BACKGROUND OF THE INVENTION
El solicitante no tiene conocimiento de la existencia en la actualidad de una invención que presente las características que se describen en la presente memoria.The applicant is not aware of the present existence of an invention that has the characteristics described herein.
Debe indicarse que actualmente las máquinas impresoras flexográficas sobre cartón ondulado, utilizan única y exclusivamente un solo cilindro de anilox en cada máquina y la operación de sustitución y limpieza de este rodillo o cilindro de anilox resulta muy laboriosa.It should be noted that currently flexographic printing machines on corrugated cardboard use only one single anilox cylinder in each machine and the replacement and cleaning operation of this anilox roller or cylinder is very laborious.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
La impresora flexográfica perfeccionada que la invención propone, se configura en si misma como una evidente novedad dentro de su campo especifico de aplicación, logrando a tenor de la misma una mejor calidad de impresión en el sector, con impresiones que precisan tramas diferenciadas de los rodillos de anilox de acuerdo a como se realice la impresión, es decir, si se realiza sobre papeles estucados o sobre papeles absorbentes.The refined flexographic printer that the invention proposes, is configured in itself as an obvious novelty within its specific field of application, achieving a better print quality in the sector, with prints that require different patterns of the rollers of anilox according to how the printing is done, that is, if it is done on coated papers or on absorbent papers.
De forma más concreta, la impresora flexográfica perfeccionada está constituida a partir de un cilindro impresor de un diámetro sustancialmente mayor al de tres rodillos cerámicos que se incorporan en la parte inferior sobre los cuales actúa una cámara de tinta con doble rasqueta desplazable, disponiendo el cilindro impresor de mayores dimensiones de dos rodillos de diámetro diferenciado posicionados en diagonal en la parte superior y lateral izquierda del mismo.More specifically, the improved flexographic printer is constituted from a printing cylinder with a diameter substantially greater than three ceramic rollers that are incorporated in the lower part on which an ink chamber with a double sliding scraper acts, providing the cylinder Large size printer with two different diameter rollers positioned diagonally on the top and left side of the same.
El cliché se incorpora en la superficie del cilindro impresor, permitiendo sobre su superficie el paso del cartón o similar, actuando a continuación los cilindros que colaboran situados en diagonal, y a la vez los cilindros cerámicos que actúan en colaboración con un cilindro de enclavamiento situado sobre una pieza posicionados a la vez equidistantes.The cliché is incorporated into the surface of the printing cylinder, allowing on its surface the passage of the cardboard or the like, then acting the collaborating cylinders located diagonally, and at the same time the ceramic cylinders that act in collaboration with an interlocking cylinder located above one piece positioned at the same time equidistant.
