Paper feed mechanism of adhesive sticker die cutting machine

Abstract

The invention discloses a paper feed mechanism of an adhesive sticker die cutting machine, and relates to the technical field of packaging and printing. The paper feed mechanism comprises a die cutting machine body, wherein a storage tray is arranged at the paper feed end of the die cutting machine body in a lifting manner, an arc-shaped paper feed plate is arranged on the die cutting machine body, a paper adsorption mechanism used for adsorbing paper pieces to the arc-shaped paper feed plate is arranged between the storage tray and the arc-shaped paper feed plate, a limit space used for limiting the paper pieces is formed between the higher part of the arc-shaped paper feed plate and the storage tray, a paper blowing mechanism used for preventing the paper pieces from adhering to each other is arranged in the limit space, and a knife biting mechanism used for transporting paper is arranged on the arc-shaped paper feed plate in a sliding manner. By means of the paper blowing mechanismand the arc-shaped paper feed plate, the condition of multilayer adhesion of the paper pieces in a paper adsorbing process and a paper transporting process is avoided, single-piece paper feeding is guaranteed, and normal running of later die cutting work is ensured.

Description

technical field [0001] The invention relates to the technical field of packaging and printing, in particular to a paper feeding mechanism for a self-adhesive die-cutting machine. Background technique [0002] Die-cutting machine is also called beer machine, cutting machine, CNC punching machine, mainly used for die-cutting, indentation and bronzing of some non-metallic materials, stickers, EVA, double-sided tape, electronics, mobile phone rubber pads, etc. Operation, lamination, automatic waste discharge, die cutting machine uses steel knife, metal mold, steel wire, exerts a certain pressure through the embossing plate, and cuts the printed matter or cardboard into a certain shape. It is an important equipment for post-press packaging processing and molding. In the die-cutting machine, it is necessary to set up a paper feeding mechanism to perform paper feeding and feeding operations on the printed paper. [0003] In the prior art, for the paper feeding of self-adhesive la...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, for the paper feeding of self-adhesive layer paper, a plurality of original paper pieces are generally stored in the form of stacks, and then the paper pieces are sucked into the paper feeding plate one by one by using the paper suction mechanism, and then transported To the die-cutting machine to realize the die-cutting operation of single paper; however, for some paper with self-adhesive layer, due to factors such as static electricity, there will be a certain amount of friction between the stacked paper Adhesion, after the paper suction mechanism absorbs the uppermost paper, there may be two or three sheets of paper attached to the bottom of this paper, which will affect the die-cutting operation of a single paper in the later stage, and there is a problem to be solved.
