Rotating die cutting device

Abstract

The invention discloses a rotating die cutting device, comprising a frame body, an upper knife roll and a lower knife roll fixed on the frame body, an upper bearing sleeve and a lower bearing sleeve respectively installed on two ends of the upper knife roll and the lower knife roll, and an upper slide block and a lower slide block respectively connected with the upper bearing sleeve and the lower bearing sleeve, wherein the rotating die cutting device further comprises a pressurizing mechanism and a pressure release mechanism; the pressurizing mechanism is matched with the upper bearing sleeve through the upper slide block; the pressurizing mechanism applies a downward force to the upper knife roll; the pressure release mechanism comprises a pressure release rod and a first elastic piece; the first elastic piece is installed on the pressure release rod; the pressure release rod is connected with the upper slide block or the lower slide block; and the first elastic piece applies an upward force to the upper knife roll by the pressure release rod. The distance between the upper knife roll and the lower knife roll is conveniently adjusted by the coordination of the pressurizing mechanism and the pressure release mechanism; in actual using process, the rotating die cutting device is quick to detach and high in repeated mounting precision without detaching the bearing sleeves when the knife rolls are grinded again; the rotating die cutting device is not only beneficial for keeping the precisions of knife rolls, and simultaneously the mounting efficiency is also largely increased.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a rotary die-cutting device. Background technique [0002] At present, the application of rotary die-cutting technology at home and abroad is becoming more and more extensive.

The rotary die-cutting device is a column structure, including four columns 1', the upper bearing block slider 2', the lower bearing block slider 3' are fixed together with the upper knife roller 4' and the lower knife roller 5' respectively , The pressurizing mechanism 6' is set on the top plate 7', and there is a wedg...

AI Technical Summary

Problems solved by technology

The assembly process of the rotary die-cutting device is complicated, and it is inconvenient to adjust the gap between the upper and lower knife rollers. The wedges are easy to loosen when the die-cutting machine is running at high speed. The damage will affect the accuracy of loading and unloading the knife roll, and the efficiency of adjusting and loading and unloading the knife roll is low, which brings great inconvenience to the user
