Title: Hiroto Imai: Innovator in Flexographic Printing Technology

Introduction

Hiroto Imai is a distinguished inventor based in Fukuyama, Japan. He has made significant contributions to the field of printing technology, holding a total of 4 patents. His innovative designs have advanced the capabilities of flexographic printing, making processes more efficient and effective.

Latest Patents

One of Imai's latest patents is a flexographic printing press designed for printing on corrugated board sheets. This invention features a printing cylinder equipped with a form plate on its peripheral surface and a receiving roll. The flexographic ink is stored between a doctor roll and an anilox roll, which rotate in opposite directions to supply ink to the form plate. The anilox roll is driven by the printing cylinder at the same peripheral speed, while the doctor roll's speed is adjusted by a speed change drive mechanism. This mechanism ensures optimal performance by varying the peripheral speed of the doctor roll based on the rotational speed of the anilox roll.

Another notable patent is a rotary die cutter that performs punching and scribing on sheets fed between a die cylinder and an anvil cylinder. The die cylinder rotates in a predetermined direction and is equipped with a knife and a scribing rule. The anvil cylinder rotates in the opposite direction and has an anvil surface to receive the knife and scribing rule. This invention includes a mechanism for adjusting the clearance between the two cylinders and a staged gear type speed changing device that allows for fine adjustments in velocity.
