Problems solved by technology

As for the ceramic anilox roller with serious clogging, the printing material blocked in the mesh hole is firmly bonded to the mesh hole after drying, and it still cannot be completely cleaned by laser high temperature.
At present, some technologies use chemical agents and lasers for treatment, but there is still the problem of possible ablation

Embodiment 1

[0035] use as figure 1 The shown anilox roller cleaning device performs anilox roller cleaning: the device includes an anilox roller 1, a roller frame 2, a laser head 3, and a laser connected to the laser head 3 through an optical fiber, and the laser head 3 is provided with a scanning vibrator mirror. During use, the laser beam emitted on the laser head 3 is aimed at the anilox roller, and the laser device can reciprocate axially along the anilox roller; the anilox roller is a Pu polyurethane anilox roller, and The length is 1.62m.

[0036] The method includes cleaning the anilox roller with a pulsed laser, the wavelength of the pulsed laser is 1064nm, the pulse frequency is 25kHz, the power is 200W, the spot diameter of the pulsed laser is 1.0mm, and the scanning line width of the galvanometer is 140mm , the scanning frequency of the galvanometer is 85Hz, and the surface speed of the anilox roller is 15mm / s.

[0037] Such as figure 2 As shown, from top to bottom are the...

Abstract

The invention belongs to the technical field of flexography printing, and relates to an anilox roller cleaning method. The anilox roller cleaning method comprises the steps that an anilox roller is cleaned through pulse laser, the wavelength of the pulse laser is 1064 nm, the pulse frequency is 20-30 kHz, and the power is 180-220 W. According to the anilox roller cleaning method, a laser cleaninglight source is controlled accurately, and thus the effects of high cleaning speed, thorough cleaning effect and no chemical reagent participation are achieved.

Description

technical field [0001] The invention belongs to the technical field of flexographic printing, and more specifically relates to a method for cleaning an anilox roller. Background technique [0002] The short ink path ink supply system is used in the flexographic printing machine, which is mainly composed of four parts: ink tank, rubber roller, doctor blade and anilox roller. Among them, the anilox roller is the core component of the flexographic printing machine, and it transfers the ink evenly to the printing plate. The anilox roller transfers the ink by the mesh, the mesh is very small, it is easy to be blocked by the solidified ink during use, thus affecting the ink transfer effect, therefore, the anilox roller needs to be cleaned regularly. [0003] Currently used anilox roller cleaning techniques include chemical immersion, ultrasonic cleaning or manual removal. These methods have the disadvantages of difficult disposal of chemical hazardous waste, long cleaning time a...
