Description

Technical Field

[0001] The utility model relates to the technical field of paper cup processing, in particular to a positioning device for paper cup processing. Background Art

[0002] Paper cups are paper containers made by mechanically processing and gluing base paper made of chemical wood pulp. They are cup-shaped in appearance. Paper cups for frozen foods are coated with wax and can hold ice cream, jam, butter, etc. Paper cups for hot drinks are coated with plastic and can even hold boiled water. Paper cups are safe, hygienic, light and convenient. They can be used in public places, hotels and restaurants. They are disposable items. During the processing of paper cups, labels or patterns can be attached to the cup body to increase the aesthetics or publicity effect. When labeling, it needs to be positioned;

[0003] During labeling process, some existing paper cups are automatically attached to the surface of the paper cups by a peeling machine directly on a conveyor belt without positioning the paper cups, which results in the labeling position being offset or tilted, resulting in poor aesthetics, and the label cannot fit well with the paper cups and is prone to falling off;

[0004] Therefore, a positioning device for processing paper cups is proposed. Utility Model Content
