Description

Technical Field

[0001] The utility model relates to the technical field of label roll installation, in particular to a label roll installation component. Background Art

[0002] A labeling machine is an automated device that applies labels to packaging. It works by using a motor to drive the labeling head, which, in conjunction with a negative pressure device, provides suction to the head at the appropriate time, removing the label from the backing paper and applying it to the packaging. The specific steps are as follows: When the label roll, which is tensioned on the labeling machine, changes direction while the backing paper is pressed against the peel plate, the front end of the label, due to its inherent rigidity, is forced to peel from the backing paper and move under the labeling head. At this point, the labeling head grasps the label and moves downward to coordinate with the movement of the label roll, completely peeling the label from the backing paper and pressing it against the packaging, completing the labeling process. The labeling head then removes suction and moves upward to reset, preparing for the next labeling operation.

[0003] The label roll mounting assembly includes an unwinding shaft and a friction brake assembly. The label roll is mounted on the unwinding shaft, and the friction brake assembly controls the unwinding speed and tension of the label roll to maintain smooth paper feeding. Existing friction brake assemblies utilize a combination of a baffle, a limit hoop, and a tightening bolt. The baffle fits over the unwinding shaft, contacting the label roll. The limit hoop presses against the baffle to limit its axial position. The limit hoop is secured to the unwinding shaft via a tightening bolt. This friction brake configuration results in unstable control and inconvenient label roll assembly and disassembly. Utility Model Content
