AI Technical Summary

Technical Problem

Existing rotary labeling machines for large drums cannot position drums of different sizes, resulting in poor labeling quality and low efficiency.

Method used

A labeling machine comprising a pressing assembly, a gear transmission system, and a label feeding assembly was designed. The pressing assembly positions the large barrel at three points, and the barrel rotates through the friction between the drive roller and the pressure roller. The gear transmission adjusts the spacing between the pressure rollers to accommodate different sizes. The label feeding assembly can apply labels at different heights, and the negative suction roller smooths the ends of the labels.

Benefits of technology

It achieves stable rotation and positioning of large barrels of different sizes, improves labeling quality and efficiency, expands the applicability of the equipment, and ensures that labels are applied flatly.

Abstract

The present application belongs to the technical field of labeling machine, and discloses a large bucket rotary labeling machine, which comprises a rack, a star wheel shaft rotatably connected to the rack, a limiting frame of arc structure fixedly installed on the rack, a driving roller rotatably arranged on the rack and extending into the limiting frame, and the outer wall of the driving roller is tangent to the inner wall of the limiting frame, two star wheel plates coaxially fixed on the outer side of the star wheel shaft from top to bottom, at least one pressing assembly for pushing the large bucket against the driving roller slidingly installed between the two star wheel plates, the pressing assembly comprising two pressing rollers symmetrically arranged and a sliding plate slidingly connected to one of the star wheel plates, and a second connecting rod rotatably connected between the two pressing rollers and the sliding plate. The present application is provided with a pressing assembly, through which the driving roller and the two pressing rollers can realize three-point positioning for large buckets of different sizes, and the rotation of the large bucket is realized by friction with the driving roller.
