Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, and more specifically, to a three-roller structure device for a round bottle labeling machine. Background Art

[0002] Labeling machines are indispensable equipment in modern packaging production. They can paste rolls of self-adhesive paper labels one by one on PCBs, products or specified packaging. At present, the types of labeling machines produced in my country are gradually increasing, and the technical level has also been greatly improved. It has changed from manual and semi-automatic labeling with low efficiency and backward design to fully automatic high-speed labeling. Fully automatic labeling machines are gradually occupying the vast market. At this stage, round bottle labeling machines mainly use three-roller structure devices.

[0003] The disadvantage is that the round bottle labeling machine is inconvenient to disassemble and replace the rubber roller accessories. When encountering many types of bottles or special-shaped round bottles, frequent changes in bottle shapes lead to the replacement of rubber rollers, which greatly affects production efficiency, so it needs to be improved.
