JG small character inkjet coding equipment
JG Small character inkjet coding equipment is a non-contact inkjet marking system controlled by a single-chip microcomputer. It exerts a certain pressure on the ink in the system by controlling the internal gear pump or by the compressed gas supplied from the outside of the machine, so that the ink can be ejected through a nozzle of a bore of tens of micrometers. And ink droplets with identical frequency and size at a certain interval will be split from continuous ink lines ejected through the crystal oscillation signal added on the top of the nozzle. And then, ink droplets are charged, respectively when passing through charging electrodes; Their electric charges are controlled by the CPU; After that, ink droplets are passed the detection electrodes to detect whether the actual electric charge and the phase are correct; Finally, charged ink droplets are deflected in the deflection electric field formed by the deflection electrode and ejected from the nozzle on different positions on the product surface, respectively to form the desired characters, patterns and other logos. Ink droplets without charged are infiltrated into the recovery tank for re-entering the ink circulation system of the machine.
