Flexographic printer with enclosures at a regulated temperature and vapor extraction

A flexographic printer with temperature-controlled sections and vapour extraction of the type comprising:

• a frame;
• at least one rotating back-pressure cylinder, which is mounted on said frame, with an exterior support surface for a band to be printed,
• at least one flexographic head comprising:
• a cliché-holder that can come into contact with the band to be printed over said back-pressure cylinder;
• and
• a print head comprising at least one inking cylinder which supplies ink from a tank to said cliché-holder cylinder;
• wherein the components of said flexographic print head can be moved closer to or farther away from said back-pressure cylinder, of which there is at least one;
• means of rotating drive for said cylinders, of which there is at least one of each and means for movement drive for said at least one flexographic print head;
• means of drying or curing a film of ink deposited on the band to be printed;
• and
• a surrounding casings,
• means of interior division which, in combination with said surrounding casing, delimit at least one first and one second sections;
• and
• means of circulating fluid through said first and second sections, of which there are at least two and at least one temperature-controlled fluid,
• with the first and second sections being sufficiently closed and insulated from each other and producing the cited fluid circulation at a flow rate that is sufficient to provide an atmosphere with a concentration of solvent vapour coming from the ink that is below a preset explosion limit in at least the second section, which contains electrical and/or electronic elements and/or devices that are associated with said means of rotation and movement drives.
