Analysis on the working principle of small character inkjet printer

The small character inkjet printer is a non-contact inkjet coding system controlled by a single-chip microcomputer.

It controls the gear pump to supply ink, and applies a certain pressure to the ink path system, so that the ink is ejected through a nozzle with an aperture of several tens of μm, and is oscillated by a crystal placed above the nozzle.< /p>

The signal splits the continuous ink line into ink droplets with the same frequency, the same size, and a certain interval.

Then, the ink droplets are charged separately when passing through the charging electrode, and the amount of electricity charged is controlled by the central processing unit CPU; then the actual position of the ink droplet is detected by the detection electrode< /p>

Whether the charged amount and phase are correct; Finally, the charged ink droplets are deflected in the deflection electric field formed by the deflection electrode, ejected from the nozzle, and hit different positions on the surface of the product.

The formation of various characters, patterns and other signs required.

Ink droplets that are not charged are sent to the recycling tank and re-enter the ink circulation system inside the machine. About the working principle of the small character inkjet printer is probably this

A process. We can find the difference between it and other cij printers in terms of working principle.

However, in general, the working principles of any cij printer are similar.

The characteristics of the product. It can perform non-contact printing on a variety of forms of large and small packages.

.Print batch number, logo, product name, expiration date, number, etc.

Use it on a certain part of the package, which is convenient and practical. And some products use invisible

ink, invisible ink for marking, this kind of invisible ink can only be read under UV light.

It is recommended that manufacturers make targeted choices during the purchase process. Although the inkjet printers are similar, they have certain effects in different industries.

Differences, manufacturers can make corresponding segmentation according to the products they produce, and select the corresponding cij printer through segmentation, so that it will be more efficient. .
