Problems solved by technology

However, in a rotary screen printing machine, since the object to be printed is in contact with the peripheral surface of the rotating screen, that is, the cylinder, when the angle of the squeegee is adjusted to move the tip of the squeegee away from the contact position, the printing quality will deteriorate. The problem

Abstract

A rotary screen printing press includes: a screen plate (201A); a squeegee (213); squeegee supporting means for supporting the squeegee (213); and a worm and a worm wheel. The squeegee supporting means includes: a supporting plate swingably supported and supporting the worm and the worm wheel; an eccentric sleeve configured to adjust the position of the center of swinging movement of the supporting plate; and a contact surface and a screw configured to limit the direction of the movement of the supporting plate. The eccentric sleeve and the contact surface and screw cooperate with each other to move the tip of the squeegee along the tangent line of an impression cylinder (100) at a position at which the screen plate (201A) and the squeegee (213) contact each other.

Description

technical field [0001] The invention relates to a rotary screen printing device for screen printing using a cylindrical rotary screen printing plate. Background technique [0002] Conventionally, a rotary screen printing machine using a rotary screen device is known as an apparatus for high-speed printing on a to-be-printed material composed of a wide range of materials such as cloth and paper. The printing method of the rotary screen printing machine is as follows: use a squeegee to press out the ink from the through holes formed on the plate of the cylindrical screen printing plate, and transfer the pressed ink to the printed matter. [0003] Usually in a rotary screen printing machine, the squeegee has a squeegee body (blade) that presses out the ink and a support (squeegee bar) that supports the blade, and when installing the squeegee to the rotary screen printing machine, the squeegee is positioned at In the rotating screen, both ends of the squeegee rod are fixed to t...
