Description

Character ink jet numbering machine shower nozzle

Technical Field

The utility model relates to the technical field of spray heads, in particular to a spray head of a character code spraying machine.

Background

The working principle of the spray head of the small character ink jet printer is as follows: the liquid ink with conductivity enters a spray cavity at the upper part of the spray head under the action of pressure, and forms spray ink flow through a spray nozzle; the piezoelectric crystal oscillator in the spray cavity generates oscillation under the action of an amplitude signal, and the oscillation breaks ink flow into ink drops with equal size in the charging electrode; the ink drops are negatively charged as they pass through the charging electrode, the charging being synchronized with the breaking of the ink drops; when the charged ink drops fly through the high-voltage deflection plate at the lower part of the spray head, the charged ink drops deflect under the action of an electrostatic electric field, characters are formed on the surface of a moving sprayed object, the ink drops which are not sprayed are not charged, therefore, the charged ink drops are not deflected, directly enter the recovery tank, and finally flow into the ink mixing tank for recycling.

The authorized bulletin number is CN207594533U discloses a little character ink jet numbering machine shower nozzle, includes: spout the chamber subassembly, spout the chamber subassembly and include: the device comprises a crystal oscillator lock nut, a crystal oscillator rod, a cavity, a spray cavity pipeline, a nozzle plate, a spray cavity pipeline connecting plate and a spray cavity bracket; the spray cavity pipeline is integrated on the spray cavity pipeline connecting plate, the spray cavity pipeline connecting plate is connected with the cavity, the front end of the cavity is connected with the nozzle plate, but the spray head is fixed by only one bolt, the stability is poor, when the ink recycling device recycles external ink, the recycled ink is easy to absorb dust in the air due to the contact of the ink and the external air, and the spray head is blocked by the dust in the recycled ink due to the fact that the filter screen is not arranged in the ink recycling tank.
