Automatic retractable labeling head device, roll labeling machine and roll labeling method

Abstract

A rolling labeling machine and automatically adjusting labeling head device, the rolling labeling machine comprising a loading tray, a paper advance mechanism, an automatically adjusting labeling head device, a detection device, and a control module; the paper advance mechanism, the automatically adjusting labeling head device, and the detection device are all electrically connected to a control device; the automatically adjusting labeling head device comprises a base (1), an adjusting piece (2), and a drive mechanism (3), the adjusting piece (2) being slidably connected to the base (1), and being driven by the drive mechanism (3) to perform adjustment; the base (1) is provided with a paper feed registration cylinder (12) and a paper exit registration cylinder (11) parallel to each other thereon; the labeling paper (200) forms an open loop in the gap between the two registration cylinders and around a adjustment plate (21), and the distance from the adjusting piece to a surface to be labeled can be automatically regulated, thus realizing the functions of avoiding an obstacle and of automatic compatibility with production line changes of products. The movement of the adjusting piece (2) can also realize precise labeling. Also provided is a rolling labeling method employing the above automatically adjusting labeling head device to achieve precise labeling.

Description

【Technical field】 [0001] The invention relates to the field of roll labeling, in particular to an automatic retractable labeling head device, a roll labeling machine and a roll labeling method. 【Background technique】 [0002] At present, and in the future, the industrial design of products will tend to be personalized, especially for civilian products. That is to say, the labeling surface of the product is no longer so single, that is, it is no longer so flat and the most prominent position up. In the roll labeling machine of the prior art, since the position of the labeling head is fixed, it is difficult to meet the needs of this reality and trend. [0003] When the surface to be labeled of the object to be labeled is lower than the outer surface of the object to be labeled, or the surface to be labeled is arched and curved, or even has reinforcing ribs, the labeling head will be squeezed, and the labeling head will be even damaged. Damage to the entire labeling machine w...

Problems solved by technology

In this method, since the object to be labeled moves with the production line, its position is uncertain, and the accuracy of the position of the label is poor, so it is difficult to achieve accurate labeling
