Technical Field

The invention relates to a labeling machine, in particular to a full-automatic labeling machine for ultrathin self-adhesive labels, which can be used for labeling ultrathin labels.

Background

The labeler is a mechanical device for sticking a coiled self-adhesive paper label (paper or metal foil) on a stuck object. Labelling machines are an indispensable component of modern packaging.

Labeling machines in China mainly go through three stages. The first stage is from the beginning of the reform opening to 1995. This stage is mainly based on the introduction and imitation of foreign labelling machines. Because the difference between the function and labeling quality of the labeling machine made in China and the difference between the labeling machines made in China and the labeling machines imported in this period are larger, the labeling machines imported in China dominate the market, and most manufacturers choose the labeling machines imported. The second phase was from 1996 to 2003. This stage is the lifting stage of chinese labeler production. The quality of the labeling machine made in China is greatly improved, and the labeling machine can basically meet the requirements of domestic manufacturers. The third stage is from 2003 to date. The stage is the mature stage of the Chinese labeling machine technology, and in the stage, manufacturers of the domestic labeling machines compete with each other and simultaneously form a situation of competition with manufacturers of foreign labeling machines, so that the labeling machines are improved, developed and innovated in the competition, are strong in innovation and gradually complete a qualitative leap.

However, the existing labeling machine for the non-setting adhesive is only suitable for the situation that the thickness of the thin film type surface paper layer is more than or equal to 35 um and the thickness of the paper type surface paper layer is more than or equal to 80 g/m²Because the adhesive sticker label has certain thickness and higher stiffness, the adhesive sticker label can be automatically tilted and separated from the release base paper to shoot to a product, and can be adhered to the product.

At present, in some products, a mark is required to be provided, and the mark occupies as little space as possible, for example, if the thickness of a label of a rechargeable lithium battery is too thick, the capacity of the lithium battery is reduced under the condition that the appearance of the lithium battery is certain. The thickness of the label is less than 30um, usually 8-15 um, and the label is difficult to be peeled off from the existing labeling machine, and automatic labeling can not be realized.
