Abstract

This utility model discloses a labeling device for packaging cartons, relating to the field of labeling technology. It includes a conveying mechanism comprising a first mounting frame with a conveyor belt on its top, the surface of which overlaps with the packaging cartons; and an adjusting mechanism including a cylinder. This utility model achieves bidirectional dynamic adjustment of the labeling mechanism's height and horizontal position by using the cylinder in the adjusting mechanism to drive the first mounting plate to rise and fall along a slide rail, while a motor drives a threaded rod to adjust the lateral position of the driving block. This allows for bidirectional dynamic adjustment of the labeling mechanism's height and horizontal position, adapting to different specifications of packaging cartons without manual intervention. Adjustment time is significantly reduced when changing product models, significantly improving the efficiency of multi-specification mixed-line production. The flexible pressing of the labeling mechanism's rubber pressing roller effectively addresses the labeling needs of curved or uneven cartons. Simultaneously, a winding motor drives a waste paper winding roller to collect the label backing paper in real time, preventing waste material entanglement from affecting production and improving equipment operational stability.
