Injection-blow molding intramode labeling technology

Abstract

The invention relates to an injection-blow molding intramode labeling technology which comprises the following steps: (1) at an injection molding station, a component is melted, stored and injected, and a parison is formed on a mandril; (2) the injection molding station and a blow molding station simultaneously open a die; (3) a rotating lifting component rises and rotates by 120 degrees; (4) a labeling manipulator extends into a blow molding cavity; (5) the labeling manipulator puts a label on a cavity formed by an upper die and a lower die; (6) the labeling manipulator goes out of the blow molding cavity; (7) the labeling manipulator grabs the label for waiting for the next cycle, and simultaneously executing step (8); (8) the rotating lifting component descends; (9) the injection molding station and the blow molding station simultaneously close the die; (10) air-blowing is performed at the blow molding station to form a container, and the label is glued with the outer wall of the container; (11) the injection molding station and the blow molding station simultaneously open the die; (12) the rotating lifting component rises and rotates by 120 degrees; (13) demoulding is performed at a demoulding station. The injection-blow molding intramode labeling technology is applicable to labeling of the packaging container.

Description

technical field [0001] The invention relates to the field of in-film labeling technology, in particular to an injection blow molding in-mold labeling technology. Background technique [0002] Injection blow molding is a blow molding method, which is generally realized on an injection blow molding machine. The equipment generally consists of three stations with a distance of 120°, which are injection molding station, blow molding station and demoulding station. It is also equipped with an automatic rotating frame. First, the plastic is made into a parison by injection molding, and then it is moved to the blow mold to be blown into a hollow product. This method can produce packaging containers for daily necessities, cosmetics, medicine, food, etc. This type of packaging container generally needs to be labeled externally. At present, the commonly used method is to use a labeling machine to label after the bottle body is produced. This method is easy to cause secondary pollutio...

Problems solved by technology

This type of packaging container generally needs to be labeled externally. At present, the commonly used method is to use a labeling machine to label after the bottle body is completed. This method is easy to cause secondary pollution during transportation and labeling, and the labeling position The accuracy is not high, the production cost is high, and the anti-counterfeiting performance is poor
