ROTARY HIGH-SPEED WEB DIE-CUTTING MACHINE AND USING METHOD THEREOF

摘要

Disclosed in the present invention is a rotary high-speed web die-cutting machine comprising a frame and a bed. The bed comprises a paper guiding device and a paper connecting device. The paper connecting device comprises a first work module and a second work module. A paper feeding gap is provided between the first work module and the second work module. A paper changing cutter and a paper changing cutter sleeve which cooperate with each other at the paper feeding gap, and a left bonding device and a right bonding device which can be lifted to the height of the paper changing cutter are respectively arranged between the first work module and the second work module. The paper guiding device comprises an upper paper guiding roller at a paper outlet of the paper feeding gap. A paper pressing roller is arranged at the upper paper guiding roller. An electric eye detection device is arranged at the paper pressing roller. The paper connecting device is used for cutting the paper. The paper pressing roller and the upper paper guiding roller cooperate with each other, thus preventing the paper at the upper paper guiding roller of the web I from shaking. The electric eye detection device can obtain a stable cursor signal, so that the paper connecting accuracy of the paper connecting device is improved greatly and the waste of the paper during the production process is reduced.
