Choose from the aspect of realization function. Today's round bottle labeling machines have achieved automatic label measurement, label delivery, and automatic correction. The principle is to use the combination of PLC+motor technology, and the program is directly on the touch screen a free man-machine interface for “fools-like” operation. On this basis, new technical methods such as positioning, air cylinder, and top pressure make the current round bottle labeling Regardless of the difference in bottle diameter, as long as you take a certain position on the bottle body, the delivery and delivery speeds have been set in the program debugging, and you no longer need to pay attention to calculating the length of the label, and avoid mechanically moving the electric eye back and forth. , It can realize automatic smart labeling. This is the primary factor to consider when purchasing a round bottle labeling machine. In this function, according to the size and shape of the round bottle, we will further consider the labeling machine we need.
The working principle of round bottle labeling machine:
At the beginning of the working process, the boxes are fed to the round bottle labeling machine at a constant speed on the conveyor belt. The mechanical fixing device separates the boxes by a fixed distance and pushes the boxes along the conveyor belt. The mechanical system of the round bottle labeling machine includes a driving wheel.
A labeling wheel, and a reel. The driving wheel drags the label tape intermittently, the label tape is pulled out from the reel, and the labeling wheel will press the label tape on the box after passing through the labeling wheel. An open-loop displacement control is used on the reel to maintain the tension of the label tape. Because the labels are closely connected to each other on the label tape, the label tape must constantly start and stop.
Tips for choosing a labeling machine for round bottle labeling machine:
1. First, consider the speed of the labeling machine: manufacturers must determine the speed of purchasing the labeling machine according to their own requirements and combined with the front-end production line. Only by comprehensive consideration can it be matched, so as to be truly better, rationalized, and unified. .
2. Secondly, choose the labeling machine degree: the labeling process belongs to the packaging process of the product, and the quality of the labeling is directly related to the appearance and marketing of the product. The labeling accuracy is high, the printing effect is good, and the label is flat, not wrinkled, and does not bubble. It is the symbol of the product, otherwise the product grade will be reduced invisibly.
3. Consider the stability of the labeling machine: a good labeling machine only has a reasonable mechanical structure design, a regular layout of various lines, a stable component structure, and high mechanical and electrical quality to ensure that the machine operates normally under long-term high-load conditions. The long-term stable operation of the standard machine can reduce the user's maintenance cost, can meet the user's reasonable production requirements, and bring quality assurance to the manufacturer and a leap in output.
