Flattening die-cutting mechanism for switching feeding mode by using floating guide roller

Abstract

The invention discloses a flattening die-cutting mechanism for switching a feeding mode by using a floating guide roller. The mechanism comprises upper and lower die carrier plates, a cutting die and a cutting die bottom plate, and is characterized in that a rear fixed guide roller, a rear floating guide roller and a paper delivery traction roller are arranged on a paper delivery side of the cutting die bottom plate, wherein the paper delivery traction roller is driven by a second servo motor; the rear floating guide roller is arranged on a floating frame; the floating frame is movably arranged and is driven by a third servo motor; during die cutting action, the second servo motor does not stop working, the floating frame is driven by the third servo motor to move, and the rear floating guide roller synchronously moves along with the floating frame; the paper length change caused by movement of the rear floating guide roller is the same as the paper length drawn by the paper delivery traction roller; the paper delivery length through the rear fixed guide roller is zero. The mechanism is applied to a flattening die-cutting machine; continuous feeding is switched into step feeding by using active action of the floating guide roller so as to finish die cutting work of a flattening, so that the production efficiency is improved and the production requirements of high-speed die cutting are met.

Description

technical field

[0001] The invention relates to a flat-press die-cutting machine, in particular to a flat-press die-cutting mechanism of the flat-press die-cutting machine. Background technique

[0002] The plate table and the press-cutting mechanism of the flat die-cutting machine are flat-shaped. When the die-cutting machine is working, the platen is pressed to the plate table through transmission to exert pressure on the plate table. Since the die-cutting action of the flat-bed die-cutting machine must be intermittent, the paper feeding action at the die-cutting mechanism must also be intermittent, which requires step-by-step paper feeding, and the biggest impact brought by step-by-step paper feeding The problem is that the paper output traction roller, the paper feed traction roller and the corresponding traction motor also work intermittently, the waiting time is long, the production efficiency is low, and it cannot better meet the production requirements of high-speed ...
