[0003] In the magnetic alignment device of the prior art, once the magnet is installed, it is tightly attached to the cylinder wall of the cylinder body during printing and cannot move
When the magnetic field generated by the magnet is used to magnetically orient the magnetic pigment flakes in the magnetic pigment, the effect of the corresponding magnetic orientation patterns formed between the magnets is the same, which cannot meet the needs of diversified magnetic orientation patterns
At the same time, the magnetic orientation device of the prior art, since the magnet is fixed on the outer surface of the cylinder wall of the cylinder body, it is very easy to cause low printing positioning accuracy and overprinting accuracy during printing, so it is difficult to meet the requirements of long boards such as large-format patterns and characters. Precision Magnetic Orientation Printing

The invention provides a magnetic orienting device for magnetic ink printing and a printing device. The magnetic orienting device comprises a drum body, a magnet pedestal and a magnet, wherein the drum body has an internal hollow structure with at least one open end and is provided with at least one first open groove which penetrates the drum wall; the magnet is arranged on the magnet pedestal; the magnet pedestal is fixedly arranged on the inner surface of the drum wall of the drum body and enables that the magnet is exposed through the first open groove and curved surfaces where the exposed outer surface and the outer surface of the drum wall of the drum body are positioned are consistent. By such arrangement, the magnet can be driven by the drum body to come into contact with a printed matter substrate during printing and rotate at the same linear velocity, and a magnetic pigment sheet in a magnetic pigment is magnetically oriented during rotation, so that magnetic orientation patterns or combined patterns of the magnetic orientation patterns and non-magnetic orientation patterns of different effects are printed.
Description
technical field [0001] The invention relates to the technical field of magnetic alignment printing, in particular to a magnetic alignment device and a printing device for magnetic pigment printing. Background technique [0002] At present, in the field of anti-counterfeiting technology, such as printing banknotes, bills, etc., it is usually necessary to use a magnetic orientation device to magnetically orient the magnetic pigment flakes in the magnetic pigment during printing to obtain various predetermined magnetic orientation patterns. [0003] In the magnetic alignment device of the prior art, once the magnet is installed, it is tightly attached to the cylinder wall of the cylinder main body during printing and cannot move. When the magnetic field generated by the magnet is used to magnetically orient the magnetic pigment flakes in the magnetic pigment, the effects of the corresponding magnetic orientation patterns formed between the magnets are the same, which cannot mee...
