Online labeling production line of non-setting adhesive labels

Abstract

The invention relates to the technical field of labeling production lines and particularly relates to an online labeling production line of non-setting adhesive labels. The online labeling productionline comprises a conveying belt, wherein the conveying belt sequentially passes through a cooling device, a weighing device, a leak hunting device, a non-setting adhesive label labeler and a stackingsystem from a blow molding machine. Through controlling the blowing of the cooling device, blow-molded products can be appropriately cooled, and contraction is accelerated; through additionally mounting a preheating plate on the non-setting adhesive label labeler, appropriate heating-up is carried out on the basis of not affecting properties of the non-setting adhesive labels, and the bonding andflowing properties of glue are improved; through reducing temperature difference between the blow-molded products and the non-setting adhesive labels, the phenomena of warping and blistering of the labels during labeling can be avoided, and meanwhile, the procedure of needing a period of time of placement due to cooling is also avoided, so that bottle blowing, leak hunting and labeling of blow molding production can be of a complete and continuous production line.

Description

technical field [0001] The invention relates to the technical field of labeling production lines, in particular to an on-line labeling production line for self-adhesive labels. Background technique [0002] For blow-molded products, due to their large volume, cooling and crystallization usually takes 24 hours, and they are easily deformed by the influence of temperature differences. However, because the products that have just come off the blow-molding production line have a certain temperature, they will be labeled immediately and will be different from the label. The plastic bottle shrinks and deforms in the later stage, resulting in the phenomenon of label warping. At present, the production line of blow molding products is to stack the products produced by the blow molding machine in a centralized manner. After cooling for one day (24 hours), they are reloaded into the production line for subsequent processing such as labeling, palletizing / packing, etc. Real-time online...
