Labeling device of pre-gluing label

Abstract

The invention discloses a labeling device of a pre-gluing label. The labeling device comprises a labeling drum. A drum body of the labeling drum is provided with at least two positioning blocks. Eachpositioning block is provided with a head positioning area, a cutting positioning area and a tail positioning area. The sequences of the three positioning areas on all the positioning blocks are consistent. During work, a head gluing area and a tail gluing area of each pre-gluing label can be located at the positions of adjacent head positioning block and tail positioning block among two adjacentgroups of positioning blocks, and the dividing area between every two adjacent pre-gluing labels is located just outside the cutting positioning area of one positioning block. A label input mechanismis arranged at a label feeding station. A laser cutter is arranged outside the labeling drum. A pre-gluing label cut by the laser cutter is conveyed to a labeling station by the labeling drum and is pasted on an auto-rotating to-be-labeled container at a label station. The labeling device of a pre-gluing label has the advantages that the pre-gluing label is cut by the laser, so that the cutting precision and the cutting efficiency are greatly improved.

Description

technical field [0001] The invention relates to the technical field of labeling equipment in a liquid filling production line, in particular to a labeling device for pre-glue labels. Background technique [0002] The labeling device in the liquid filling production line mainly includes two parts: the label cutting mechanism and the labeling mechanism. [0003] The label cutting mechanism mainly includes: a label cutting roller, a knife roller and a label sending roller group. Wherein, the roller body of the label cutting roller is hollow to form the inner cavity of the label cutting roller, and the surface of the roller body is provided with a number of adsorption holes that communicate with the inner cavity of the label cutting roller, and the inner cavity of the label cutting roller communicates with the negative pressure device. Negative pressure is formed in the cavity of the marking roller and the adsorption hole under the action of the cutting roller, so that the labe...

Problems solved by technology

[0006] At present, the labeling device has the following defects: 1. An additional mechanical knife is required in the label cutting mechanism, that is, a mechanical knife is used to cut the partition area. Such a structure is relatively complicated, the mechanical assembly precision is high, the installation is cumbersome, and the knife is easy to wear

2. With the continuous improvement of beverage filling production level, pre-coated labels with glue appear, that is, pre-glued labels. The pre-glued labels to be cut are connected end to end, and the back of the head and the back of the tail of each label are pre-coated. Coated with glue, there is a dividing area for cutting between two adjacent pre-glued labels. When cutting such pre-coated labels, the cutter in the above-mentioned labeling device is easy to stick glue, so that Knives often fail to function properly and cut inefficiently
