Detailed Description

The present invention is described in detail below with reference to the attached drawings:

example one

As shown in fig. 1, 2, and 3, a laser plate roller device for three-dimensional engraving comprises a bracket 1 formed by welding angle steel and a plate roller capable of being rotated on the bracket 1, wherein the plate roller is made of steel and comprises a cylindrical substrate 21 and a plurality of accommodating cavities 22 recessed from the cylindrical surface of the substrate 21 to the axial direction thereof to form a space for accommodating ink, wherein at least two accommodating cavities 22 with different distances from the bottom to the surface of the substrate 21 are provided, the plurality of accommodating cavities 22 with different distances, surface shapes of the substrate 21 and different areas are combined to form printed patterns with different fancy shapes, and the accommodating cavities 22 are provided with different depths to accommodate different amounts of ink and react with the printed patterns, so that the ink with different thicknesses and the three-dimensional patterned patterns are presented. The utility model provides a hold chamber 22 for the base member 21 surface shaping through laser engraving at version roller, the same tolerance control level that has in holding chamber 22, the adjacent chamber that holds transition also has good structural shape, guarantees that the space surface quality who holds printing ink is good, the shape rule, and then provides good printing ink stamp quality. The three-dimensional pattern is formed at one time by the plate roller, so that the plate roller has good economy.

In this embodiment, it produces the angular edge 24 that has at least one and set up along its border extending direction to hold chamber 22 opening border through laser engraving (this embodiment is 1 that the contained angle is 90, can be two arriss that constitute and be equivalent to the chamfer structure in other preferred embodiments), through angular edge 24, it is as its inside and outside boundary to provide each opening that holds chamber 22, can prevent that the printing ink in this holding chamber 22 from oozing to the outside through the pressure of angular edge 24's angle to the cloth and isolation effect when stamp to the cloth, improve between the fashioned solid pattern, transition stereology between pattern and the cloth, improve the quality and the aesthetic property of output.

In this embodiment, the support roller 3 and the ink fountain 4 are further mounted on the bracket 1, and the support roller 3 and the ink fountain 4 are sequentially arranged in a tangential manner along the rotation direction of the plate roller. Wherein the supporting roll 3 and the plate roller synchronously rotate through devices such as a chain, and the cloth to be printed passes through the supporting roll 3 and the plate roller to realize printing. The successive arrangement in the direction of rotation allows a circulation of printing ink to be obtained between the ink bath 4 and the backing roll 3 at the surface of the plate roll.

In the present embodiment, the backup roll 3 has a soft layer 31 made of a material having a certain elasticity and support property, such as rubber or POM, which is in contact with the roll and is subjected to compression deformation around the surface thereof (in other preferred embodiments, the soft layer 31 may be directly provided as the entire backup roll 3, and may be able to perform its function). During printing, the roller extrudes and deforms the soft layer 31 on the surface of the supporting roller 3, and the deformation amount of the soft layer is different according to different depths of the accommodating cavities 22, namely, the cloth to be printed is completely and comprehensively and correspondingly pressed on each accommodating cavity 22 to completely realize contact transfer of printing ink. By this arrangement, together with the angular edges 24, an effective processing of a cloth, such as a fleece, which is difficult to print, can be achieved.

In the embodiment, the axes of the plate roller and the supporting roller 3 are parallel and are positioned in the same horizontal plane, so that the extrusion elastic printing action between the plate roller and the supporting roller is stable, and the output quality is ensured.

In this embodiment, a scraping blade 41 tangent to the plate roller is disposed at the edge of the ink tank 4, and a scraping strip 42 opposite to the extension direction of the scraping blade and pointing to the surface of the plate roller and forming an elastic deformation stop with the surface of the plate roller is disposed at the edge of the scraping blade 41. The ink tank 4 stores printing ink, the scraper 41 and the scraping strip 42 are made of elastic materials, and the ink cannot remain on the unprocessed part of the surface of the printing roller (namely the part which does not need printing on the corresponding cloth) through the stopping and ink scraping actions on the surface of the printing roller, so that the ink pollution which influences the output quality is avoided.

In this embodiment, the scraping strips 42 are multiple segments sequentially distributed along the edge direction of the scraping plate 41, so as to better adapt to different accommodating cavity structures 22 distributed in the length direction of the printing roller, and each segment of the scraping strip can adapt to adaptive deformation of the surface of the corresponding printing roller for scraping ink.

Example two

The technical solution in the second embodiment is similar to that in the first embodiment, and the difference is as follows:

as shown in fig. 4, in this embodiment, the bottom of the accommodating cavity 22 is a rectangular array and is uniformly distributed with dots 23 for accommodating ink, the dots 23 are used for further improving the printing and transferring capability and quality of the accommodating cavity 22, and by arranging the dots 23, the ink can be more completely separated from the adhesion of the accommodating cavity 22 during transferring, so that the quality of the produced surface is improved.

In this embodiment, the opening diameter and depth of the dots 23 at the bottom of different cavities 22 increase linearly with the distance from the bottom of the cavity 22 to the surface of the substrate 21. The depth adjustment of the printed pattern can be realized by controlling the depth of the dots 23. Such as larger, darker dots, which hold a greater amount of ink, print patterns that are darker and/or thicker, and likewise lighter dots, which are used to print lighter and/or finer patterns. The opening diameter and the depth of the mesh points 23 at the bottoms of the different accommodating cavities 22 are linearly increased or decreased along with the increase of the distance from the bottoms of the accommodating cavities 22 to the surface of the base body 21, so that the color depth of the integrally produced pattern can be correspondingly adjusted, and the better presenting effect is realized. Meanwhile, the setting mode enables the whole ink amount and the expected transfer effect to be controllable, and facilitates pattern design and processing of the printing roller.

EXAMPLE III

The technical solution in the third embodiment is similar to that in the second embodiment, and the difference is as follows:

in this embodiment, the opening diameter and depth of the dots 23 at the bottom of different cavities 22 decrease linearly with the distance from the bottom of the cavity 22 to the surface of the substrate 21. Thereby achieving the reverse color-toning effect of the second embodiment.

The above embodiments are only described for the preferred embodiments of the present invention, and are not intended to limit the concept and scope of the present invention, and the various modifications and improvements made by the ordinary person in the art without departing from the design concept of the present invention all fall into the protection scope of the present invention.
