US 2023/0132899 A1 · SCREEN PRINTING APPARATUS

Abstract

A screen-printing apparatus for repeatedly marking an indicium at regularly spaced intervals or predefined discrete intervals on a surface or medium. The screen-printing apparatus includes a wheel mounted to a housing. A screen frame can be mounted to a housing that can interchangeably receive a screen having void(s) of a shape that corresponds to the indicia to be printed. The screen-printing apparatus also has an ink supplying unit that sprays ink over the top surface of the screen. A solenoid operably coupled to the ink supplying unit for triggering the ink supplying unit. The solenoid and the wheel are operably coupled to a control unit, the control unit can receive readings from the wheel about the distance covered by the wheel on the surface and based on the readings can trigger the solenoid at predefined intervals.

Dependent claims

A screen-printing apparatus comprising:

a housing;
a wheel rotatably mounted to the housing, the wheel configured to roll on a surface;
a digital encoder mounted to the housing and operable coupled to the wheel, the digital encoder configured to measure rotations of the wheel;
a screen frame mounted to the housing, the screen frame configured to interchangeably receive a screen, the screen having one or more voids, the screen is positioned such as when ink is sprayed on a top surface of the screen, a portion of the ink passes through the one or more voids onto the surface forming an indicia;
an ink supplying unit coupled to the housing, the ink supplying unit has one or more nozzles in spatial relationship with the screen;
and
a solenoid mounted to the housing and operably coupled to a control unit and the ink supplying unit, wherein the solenoid upon triggering by the control unit activates the ink supplying unit to spray the ink through the one or more nozzles on the top surface of the screen.
