Label station of adhesive sticker labeling machine

Abstract

The invention discloses a label station of an adhesive sticker labeling machine. The station comprises a label roll, an unwinding mechanism, a label feeding mechanism, a stripping mechanism and a winding mechanism; the label feeding mechanism comprises a buffer conveying mechanism, a label feeding power roller group and a label bottom paper recovery power roller group, wherein the buffer conveyingmechanism is arranged between the unwinding mechanism and a guide roller; the buffer conveying mechanism comprises a main shaft, wherein a guide cylinder body is arranged outside the main shaft, theguide cylinder body is divided into a plurality of circular arc-shaped guide plates, each circular arc-shaped guide plate is movably supported on a guide rod, each guide rod is fixed on the main shaftand is radially arranged along the main shaft, each circular arc-shaped guide plate can move back and forth on the corresponding guide rod, and at least one counterweight mechanism is arranged between each circular arc-shaped guide plate and the main shaft. The station has the advantages that the failure of label jam is effectively avoided, the label buffering and conveying are stable, and labelbottom paper can be effectively prevented from being broken in the conveying process.

Description

technical field [0001] The invention relates to the technical field of labeling machines, in particular to a labeling station in a self-adhesive labeling machine. Background technique [0002] The self-adhesive labeling machine mainly includes a main machine and a labeling station. The main machine is used to rotate and transport the containers to be labeled to the labeling station, and output the labeled containers. The labeling station is mainly equipped with a label roll, an unwinding mechanism, a label feeding mechanism, a peeling mechanism, and a winding mechanism. The label to be pasted is pasted on the backing paper and rolled into a roll, and the rolled label is called a label roll. The roll-out mechanism is used to roll out labels coated with self-adhesive and pasted on the backing paper. The label feeding mechanism usually includes: a buffer conveying mechanism, a label feeding power roller group and a label bottom paper recovery power roller group. Among them, ...

Problems solved by technology

[0003] The label station in the self-adhesive labeling machine with the above structure has the following defects: 1. The label spread through the buffer conveying mechanism is unstable. Unstable delivery

2. When the airflow is used for buffer conveying, the label is easily blocked in the guide roller outside the buffer conveying, resulting in card label failure
