Problems solved by technology

[0013] Due to the low thermal conductivity of some materials used to make anilox sleeves, the traditional cooling system has the disadvantage of rather slow temperature control, so it cannot meet the special needs of flexographic printing machines
[0014] Moreover, also due to the low thermal conductivity of the sleeve, existing cooling systems must operate with large temperature differences relative to the outer surface of the sleeve and are therefore not particularly energy efficient
[0015] Another disadvantage of existing cooling systems is that they control the temperature of the anilox roll only by cooling and not by heating

Embodiment Construction

[0029] With reference to these figures, an anilox roll, in particular for a flexographic printing machine, is indicated generally by the reference numeral 1 and comprises a sleeve cylinder 2 which is driven around its own axis by a flexographic printing machine. 4 fixed structure 3 rotating support.

[0030] In general, the flexographic printing press 4 expediently has a front side 4a, on which the operator can access the sleeve cylinder 2, and a rear side 4b, which is opposite the front side.

[0031] Preferably, the fixed structure 3 of the flexographic printing machine 4 comprises a first support shoulder 3 a and a second support shoulder 3 b, which are substantially parallel to each other and spaced from each other along the axis of the sleeve cylinder 2 . More specifically, a first support shoulder 3a is provided on the front side 4a of the flexographic printing press 4 and suitably has at least one opening 3c for access to the sleeve cylinder 2, while a second support sh...

Abstract

An anilox roller, particularly for flexographic printing machines, which comprises a sleeve cylinder (2) rotatably supported about its own axis by the fixed structure (3) of a flexographic printing machine (4), and an anilox sleeve (5), which has a tubular body (6) provided, on its outer side wall, with an anilox surface (5a) which can be axially fitted on and removed from the sleeve cylinder (2). According to the invention, means are provided for the forced circulation of a temperature control fluid within the tubular body (6).

Description

technical field [0001] The invention relates to an anilox roll, especially an anilox roll for a flexographic printing machine. Background technique [0002] As we all know, in a printing press, the transfer of ink to the printing material is mainly done through three rollers: anilox roller, plate roller and pressure roller. [0003] Specifically, the function of the anilox roll is to ink the printing plate carried by the plate roll, which in turn prints the material supported by the pressure roll. [0004] Usually the side of the anilox roller has an anilox surface, that is to say it has a plurality of ink pockets which are open to the outside. Ink is stored inside the ink well via the inking element. Inking elements known in the printing process have closed chamber doctor blades. [0005] It should be noted that due to some practical reasons when changing the printing format, in most flexographic printing machines, the anilox roller is not formed as a whole, but is forme...
